CONTINUED FROM THE MAY 31, 2011 FAST-TRACK HEARING. FROM: Brian Froelich, AICP, Associate Planner APPROVED: Debbie Pedro, AICP, Planning Director RECOMMENDATION: That the Planning Commission: Review, make comments, and forward a recommendation that, based on the Initial Study, the City Council adopt the Mitigated Negative Declaration and Mitigation Monitoring Program in Attachment 3; and Forward a recommendation that the City Council approve the requested Site Development Permit and Variance for the project, citing the findings in Attachment 2 and subject to the conditions of approval in Attachment 1. BACKGROUND The subject property is located off of Page Mill Road at the end of South Fork Lane. The lot has a rectangular shape and no roadway frontage but is accessed though a driveway easement traversing the lot immediately to the west. The property has a net size of 2.454 acres with an average slope of 29%. The site is currently developed with a primary residence, two detached buildings, and a swimming pool. The lot was created in 1973 via a two -lot subdivision. The site contains a 10 foot wide Pathway Easement along the north and eastern property boundaries. Other site characteristics include: over 50 heritage oak trees, primarily native vegetation, hillside location, and a secluded building site. The project was originally heard at the Fast-track hearing on May 31, 2011. At that hearing, representatives from the National Trust for Historic Preservation (NTHP) submitted a letter dated May 27, 2011 (Attachment 4) that questioned the project's eligibility for a Categorical Exemption under CEQA (California Environmental Quality Act). The site was formerly owned and occupied by Pulitzer Prize winning author, Wallace Stegner from 1949 to 1993. The NTHP letter requested that the Town, as the Lead Agency, conduct further environmental review prior to taking action on the project. Lands of Yong Planning Commission May 3, 2012 Page 2 As a result, the hearing was continued to a date uncertain. The Town subsequently commissioned and oversaw the preparation of two supplemental environmental reports prepared by historic preservation consultants (Attachments 5 & 6) and prepared an Initial Study and a Mitigated Negative Declaration in response to the concerns raised by NTHP. The concerns raised by NTHP and resulting Mitigation Measures have prompted a change to the scope of work for the project. The project applicant is now proposing to retain the existing detached, writing studio to the location of the existing former study/guest cottage. A Floor Area and Development Area Variance are requested to allow for the preservation and relocation of the writing studio. DISCUSSION Site Data: Gross Lot Area: 2.454 acres Net Lot Area: 2.454 acres Average Slope: 29% Lot Unit Factor: 1.455 Area Maximum Proposed Existing Increase Left Development 11,958* 12,309 10,189 2,120 +351** Floor 7,348 7,602 2,249 5,353 +254** *Increased MDA Per Section 10-1.502(b)(6) (Solar Ordinance) **Variance Request Site and Architecture The 2.454 acre site has a 29% slope that ascends from the northwest corner to the southeast corner. The building site location is a knoll top but the site is not located on a ridgeline. The proposed new construction would be in the location of the existing residence and writing studio of the late Wallace Stegner. Under the proposed Site Development Permit, the existing single family residence, carport, and a detached former study/guest cottage would be demolished. The author's writing studio, located adjacent to the north side of the residence, would be preserved and relocated on the property, at the current site of the former study/guest cottage a short distance west of the residence (approximately 90 feet southwest). The design of the proposed residence utilizes all of the allowable floor area and development area for the residence, driveway and accessory structures. The proposed site layout includes the primary building, relocation of the writing studio, new driveway plan, decking and swimming pool. The exterior building materials include plaster and stone siding with aluminum canopies, windows and detailing. i s Lands of Yong Planning Commission May 3, 2012 Page 3 The residence includes a full basement (3,647 so and swimming pool to the southwest of the residence. The building floor plan includes a secondary dwelling unit in the basement, an attached three -car garage and two surface parking spaces are accommodated within the driveway layout. The proposed residence complies with setbacks and height standards per Title 10 of the Municipal Code. Driveway & Parking The proposed driveway will utilize the existing access from South Fork Lane. The subject property has right of access over the adjacent lot to the west. The driveway terminus incorporates two (2) surface parking spaces and a firetruck turnaround. The proposal includes an overall reduction of driveway paving. The driveway has a curve as it turns toward the residence. The proposed design shortens the curve and approaches the building site from a lower elevation. The design complies with Town and Fire Department standards. Outdoor Li hg ting Outdoor lighting is shown on the elevation plan sheets. Standard lighting is proposed, with two (2) fixtures per double door exit, one (1) fixture per single door exit, and several building perimeter fixtures at stairways or at distance from exits. The standard lighting Condition 7 for outdoor lighting, requires that fixtures be down shielded or have frosted/etched globes. The applicant is required to submit outdoor landscape lighting details with the required landscape screening plan. Grading & Drainage The Engineering Department has reviewed the project Civil Engineering plans and has determined that the proposal complies with the Grading Policy and the Town's drainage standards. Grading quantities include: • 3,556cubic yards of cut • 76 cubic yards of fill • 3,480 cubic yards export The site grading and cut are primarily for the basement excavation, swimming pool excavation, and driveway realignment. The drainage design directs water into catch basins and area drains conveyed into 4" pipes that connect to two (2) energy dissipaters. The dissipaters are located 60 and 80 feet from adjacent property lines to allow ground absorption. The project Engineer's drainage calculations demonstrate that the post development runoff will not exceed the predevelopment totals. Lands of Yong Planning Commission May 3, 2012 Page 4 Geotechnical Review The applicant has provided a Geotechnical Investigation prepared by Murray Engineers Inc. The proposed building site is located 25 to 30 feet from the Monta Vista fault. Therefore, the project Geotechnical Consultant has recommended that the basement have a reinforced mat slab that a minimum of 10 inches thick. The Town's Geotechnical consultant has peer reviewed the proposal and recommended standard conditions that include follow up documentation and inspection by the project geologist (Conditions 24a & 24b). Trees & Landscaping The site is naturally landscaped and contains over 50 heritage oak trees (12" and larger in truck diameter). The applicant has provided an arborist report prepared by Kielty Arborist Services dated October 12, 2010 (Attachment 7). The report analyzes the health and condition of 24 oak trees in the closest proximity to the proposed construction project and staging operations. The applicant requests removal of two heritage oak trees, 18" and 20" specimens as part of the project. The project arborist comments that the trees are in poor and fair condition, respectively. The 18" tree has grown to within three (3) feet of the existing residence and could become a safety and maintenance concern. The 20" tree is in fair health but is located immediately next to an existing retaining wall proposed for removal. Per LAHMC Section 12-2.306, mitigation plantings at a 2:1 ratio with 24" box sized oak trees are recommended per Condition 21 of this report. Tree protection measures are also recommended per Condition 23. Green Building Ordinance The applicant has submitted a GreenPoint checklist in compliance with the Town's Green Building Ordinance. The building is designed to achieve 102 points in the GreenPoint Rated certification program. Fire Department Review The Santa Clara County Fire Department reviewed the plans and has required that the building be sprinklered, the driveway accommodate a standard Fire Truck Turnaround, and provide a public fire hydrant at a location to be determined. (Attachment 16) Sanitation The Santa Clara County Health Department has preliminarily approved the residence and septic system layout. C Lands of Yong Planning Commission May 3, 2012 Page 5 Public Comments The Town has received written support of the project from neighbors representing six (6) different properties. Several of the neighbors have lived in the neighborhood for some time and where neighbors of the former owner, Wallace Stegner. (Attachment 8) The Town has received a comment letter regarding the CEQA documents from resident Lester D. Earnest dated April 13, 2012. JRP Historical Consulting has prepared a response to the CEQA questions raised in Mr. Earnest's letter. (Attachments 9 & 10) The Town has also received letters from two San Francisco residents, Joan Reinhardt Reiss and Susan Alexander. The letters request that the Town consider moving the writing studio to a site near Town Hall for public access. (Attachment 11) Town Committee's Review The Pathways Committee has recommended that the applicant maintain the existing Pathways on the property. (Attachment 12) The Open Space Committee has recommended that an Open Space Easement be placed over the northwestern slope on the property to preserve the steep slopes and oak grove. The recommended easement area totals approximately 0.58 acres. (Attachment 13) The Environmental Design and Protection Committee commented that the MDA and MFA are at the maximum and that two heritage oak trees are to be removed. (Attachment 14) Variance Variances provide relief from development standards where a particular property has a limitation or deficiency that disallows the property from being developed in a manner consistent with similarly zoned properties. In order to approve a Variance, the Planning Commission must find that the site presents inherent difficulties. In order to accommodate the identified historic resource on the property, the applicant is requesting a Floor Area Variance to exceed the MFA by 254 square feet and a Development Area Variance to exceed the MDA by 351 square feet. As designed the project otherwise meets all of the Town's Development standards. The proposed overages relate only to the writing studio and associated decks and landings needed around the structure. The unusual circumstance of a historic resource on a private property is only applicable to a small number of properties within the Town. Granting of a Variance would not constitute a special privilege because so few other properties within the same zoning district contain historic resources. Further, both Variances are relatively insignificant with regard to overall site planning and layout, constituting approximately a 3% overage of the Lands of Yong Planning Commission May 3, 2012 Page 6 MDA and MFA. Findings for approval of the Variances are included in Attachment 2 of the staff report. ENVIRONMENTAL REVIEW (CEQA) In compliance with the California Environmental Quality Act (CEQA), an Initial Study, Mitigated Negative Declaration and Mitigation Monitoring Program have been prepared for the project. A Notice of Intent to adopt a Mitigated Negative Declaration was published in the Town Crier on April 11, 2012. The notice was also submitted to the Santa Clara County Clerk's Office for a 20 day public review period which began on April 10, 2012 through April 30, 2012. The Mitigated Negative Declaration must be adopted by the City Council before approving the project. In order to recommend adoption, the Commission must find that all potentially significant environmental effects are addressed through the proposed mitigation measures. As the Lead Agency, the Town of Los Altos Hills commissioned Circa Historic Property Development to prepare a Base -Line Historic Resources Assessment and JRP Historical Consulting to prepare a Mitigation Analysis and Identification Report. Circa analyzed the property for both the National Registry of Historic Places (NRHP) criteria and the California Registry of Historical Resources (CRHR) and concluded that the writing studio meets the National Register's criteria while the primary residence and guest cottage are contributing buildings. The historical resource on the property includes three contributing components: the main residence, former study/guest cottage, and writing studio. In addition, the rural location and setting contributes to the significance of the resource. While all of these elements contribute the significance of the resource, according to the Circa Assessment, only the writing studio meets the criteria for individual listing in the NRHP and CRHR, as it is most directly associated with the writing career of Stegner. The applicant is proposing to preserve the writing studio and relocate it to the site of the former study/guest cottage west of the main residence on the property. In compliance with the historical resource provisions of CEQA, preservation of the writing studio is required to be conducted in a manner consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings. Mitigation Measure Documentation and recordation of the main residence, former study/guest cottage, and writing studio shall precede any construction, demolition, or relocation activities. This mitigation measure must be undertaken by a qualified historian / architectural historian (under the Secretary of the Interior's Professional Qualification Standards). a Lands of Yong Planning Commission May 3, 2012 Page 7 Documentation shall follow NPS standards for HABS Historical Report Guidelines, as such standards will ensure the appropriate level of written and photographic recordation of the property's significant historic context and character -defining features. The documentation of the former Stegner property shall approximate HABS Level II documentation and include: a) select existing drawings that would be photographed; b) photographs following the NPS photo policy, of exterior and interior views, along with historic views; and c) written data providing history and description of the property. Additionally, the photographs, shall include a view that illustrates the view from the writing studio to help illustrate the setting in which Stegner worked. ATTACHMENTS 1.

S Lands of Yong Planning Commission May 3, 2012 Page 17 ATTACHMENT 2 FINDINGS OF APPROVAL FOR A FLOOR AREA AND DEVELOPMENT AREA VARIANCE LANDS OF YONG, 13456 SOUTH FORK LANE File # 249-10-ZP-SD-GD-VAR-IS-MND 1. Because of exceptional and extraordinary circumstances applicable to the subject property, including size, shape, topography, location or surroundings, the strict application of the provisions of this Title is found to deprive such property of privileges enjoyed by other properties in the vicinity and under identical zoning classification; The subject property is unique and extraordinary because it contains a historic resource. From an environmental (CEQA) perspective, a historic resource is the same as other environmentally sensitive features like a creek, fault trace, or a stand of heritage trees. Variances can be issued to allow reasonable development of properties with environmental features that are required to be projected. In this case, the preservation of the historic resource, a building requires a Floor Area and Development Area Variance to be preserved and not to deprive the property owner of their development right and potential. 2. Upon the granting of the variance, the intent and purpose of the applicable sections of the Zoning Ordinance will still be served and the recipient of the variance will not be granted special privileges not enjoyed by other surrounding property owners. The granting of the Variance would not be a grant of special privilege. The MFA/MDA overage is approximately 3% in each category. This small overage does not create any difficulties for the project in compliance with other Town requirements nor does it create a major change to the Town's land use pattern. Many properties of similar acreage are developed with greater intensity. The preservation of a relatively small building (260 sf) also makes this case unique. All projects involving a historic resource will be unique. 3. The granting of such variance will not be materially detrimental to the public welfare or injurious to the property, improvements or uses within the immediate vicinity and within the same zoning district. The granting of the MFA/MDA Variance will not adversely impact neighboring properties because the proposed project is otherwise compliant with all Town standards. Many properties in Town are developed with greater intensity than proposed with this project. Lands of Yong Planning Commission May 3, 2012 Page 18 4. The variance will not authorize a use or activity which is not otherwise expressly authorized by the Zoning District regulations governing the parcel of property. Primary and accessory buildings are permitted uses in the R -A zoning district. Attachment 3 TOWN OF LOS ALTOS HILLS MITIGATED NEGATIVE DECLARATION PROJECT TITLE: New Residence, Basement, Swimming Pool, and Relocation of a Detached Accessory Building. Lands of Yong, 13456 South Fork Lane PREPARED BY: Brian Froelich, AICP, Associate Planner NAME AND ADDRESS OF PROJECT SPONSOR: Yew -Nam and Wan -Lei Yong 13456 South Fork Lane Los Altos Hills, CA 94022 LOCATION OF PROJECT: 13456 South Fork Lane, Los Altos Hills, CA 94022 Assessor's Parcel Number: 182-10-039 PROJECT DESCRIPTION: A Site Development Permit for the construction of a 7,337 sq. ft. new single family residence with an attached secondary dwelling unit, a swimming pool, and associated site improvements. The application includes the demolition of an existing single story main residence and former study/guest cottage and the relocation of an existing 260 sq. ft. writing studio to the location of a former study/guest cottage located approximately 90 feet to the northwest of the proposed main residence. FINDING: The Town of Los Altos Hills has completed a review of the proposed project, and on the basis of the attached Initial Study, has determined that the project, as mitigated, will reduce impacts to a less than significant level. MITIGATION MEASURES INCLUDED IN THE PROJECT: MITIGATION MEASURE #1: Air Quality Measure: Dust control measures shall be implemented during construction as follows: • All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day. • During grading operations graded areas shall be watered on a continuous basis. • All haul trucks transporting soil, sand, or other loose material off-site shall be covered. •. All visible mud or dirt track -out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. MITIGATION MEASURE #2: Oak Tree Replanting: The applicant shall plant two (2), 24 inch box sized oak trees for each Heritage Oak Tree removed. The location of the replacement plantings shall be determined at the time of Landscape Screening Plan review. MITIGATION MEASURE #3: Oak Tree Protection: Tree protection measures shall be implemented and installed prior to start of demolition or grading as recommended by Kielty Arborist Services in their report dated October 12, 2010. An ISA Certified Arborist shall certify, in writing, that the Kielty Arborist Services measures were implemented and report any updates or changes to the tree protection plan, prior to final inspection of the new residence. MITIGATION MEASURE #4: Documentation and Recordation: Documentation and recordation of the main residence, former study/guest cottage, and writing studio shall precede any construction, demolition, or relocation activities. This mitigation measure must be undertaken by a qualified historian / architectural historian (under the Secretary of the Interior's Professional Qualification Standards). Documentation shall follow NPS standards for HABS Historical Report Guidelines, as such standards will ensure the appropriate level of written and photographic recordation of the property's significant historic context and character -defining features. The documentation of the former Stegner property shall approximate HABS Level II documentation and include: a) select existing drawings that would be photographed; b) photographs following the NPS photo policy, of exterior and interior views, along with historic views; and c) written data providing history and description of the property. Additionally, the photographs shall include a view that illustrates the view from the writing studio to help illustrate the setting in which Stegner worked. The Town will retain the documentation for public benefit and copies of the documentation will be offered to interested parties identified during project approval process, particularly all relevant historical organizations as well as organizations and collections dedicated to the work of Wallace Stegner. The Table below includes a list of recipients; however recipients need not be limited to those listed. In addition, the HABS documentation will serve as a baseline of information for the preservation of the writing studio, which will be undertaken as part of the proposed project. The proposed documentation is intended for public dissemination and not intended to be reviewed by NPS or for transmittal to the Library of Congress and therefore, will not be a full -definition, HABS dataset.

The documentation will serve to provide an archival record of these physical characteristics, as well as a record of the property's relationship to the significant writing career of Wallace Stegner. Geotechnical Plan Review: The project Geotechnical Consultants shall review and approve all geotechnical aspects of the project building and grading plans (i.e. site preparation and grading, site drainage improvements and design parameters for foundations and retaining walls) to ensure that their recommendations have been properly incorporated. • The Project Geotechnical Consultant shall review the proposed energy dissipater placement in the northeastern portion of the property and recommend any appropriate revisions from a geotechnical perspective. The results of the Geotechnical Plan Review shall be summarized by the Geotechnical Consultant in a letter and submitted to the Town Engineer along with other documents for building permit plan check. MITIGATION MEASURE #6: Geotechnical Construction Inspections: The Geotechnical Consultant shall inspect, test (as needed), and approve all geotechnical aspects of the project construction. These inspections shall include, but not necessarily be limited to: site preparation and grading, site surface and subsurface drainage improvements, and excavations for foundations, and retaining walls prior to placement of steel or concrete. At the end of project construction, the consultant shall inspect the completed site drainage improvements to confirm compliance with geotechnical standards. The results of these inspections and the as -built conditions of the project shall be described by the Geotechnical Consultant in a letter and submitted to the Town Engineer for review prior to final inspection. MITIGATION MEASURE #7: Construction Hours: Noise generating construction activities shall be limited to Monday through Saturday between the hours of 8:00 am and 5:30 pm. and shall not exceed allowable noise standards set forth in the Municipal Code. No heavy noise generating equipment is allowed to be used on Saturdays and no construction is allowed on Sundays or holidays as noted per Chapter 7, Sec.5-7-01 of the Los Altos Hills Municipal Code.

DISCUSSION: According to Bay Area Air Quality Management District (BAAQMD) CEQA thresholds, a project that generates more than 54 pounds per day of reactive organic gas (ROG), nitrogen oxide (NOx), or fine particulate matter (PM2.5); or 82 pounds per day of course particulate matter (PM10) would be considered to have a significant impact on regional air quality. Excavation, Grading, and Hauling equipment will be used to remove 3,480 cubic yards of earth material from the site. Dust causing activities would be temporary and will occur during grading and initial construction activities. With mitigation during the grading activities, this project will have a less than significant impact on regional air quality. MITIGATION MEASURE #1: Air Quality Measure: Dust control measures shall be implemented during construction as follows: • All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day. • During grading operations graded areas shall be watered on a continuous basis. • All haul trucks transporting soil, sand, or other loose material off-site shall be covered. • All visible mud or dirt track -out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day.

DISCUSSION: The project proponent proposes to remove two (2) Heritage Oak Trees to accommodate the project. Title 12 of the Los Altos Hills Municipal Code defines a Heritage Oak Tree as follows: Any tree of the genus quercus, including, but not limited to, Valley Oak (Quercus lobata), California Live Oak (Quercus agrifolia), Black Oak (Quercus kelloggii) and Blue Oak (Quercus douglasii) that has a trunk or multiple trunk thirty-six (36) inches in circumference (approximately twelve (12) inches in diameter) at a point four (4) feet above the root crown The applicant has provided an arborist report prepared by Kielty Arborist Services dated October 12, 2010. The report analyzes the health and condition of 24 oak trees in the closest proximity to the proposed construction project and staging operations. Per LAHMC Section 12-2.306, mitigation plantings and tree protection measures are recommended. MITIGATION MEASURE #2: Oak Tree Replanting: The applicant shall plant two (2), 24 inch box sized oak trees for each Heritage Oak Tree removed. The location of the replacement plantings shall be determined at the time of Landscape Screening Plan review. MITIGATION MEASURE #3: Oak Tree Protection: Tree protection measures shall be implemented and installed prior to start of demolition or grading as recommended by Kielty Arborist Services in their report dated October 12, 2010. An ISA Certified Arborist shall certify, in writing, that the Kielty Arborist Services measures were implemented and report any updates or changes to the tree protection plan, prior to final inspection of the new residence.

V. CULTURAL RESOURCES — Would the project: a) Cause a substantial adverse change in the significance of a historical resource as defined ❑ Q ❑ ❑ in ' 15064.5? b) Cause a substantial adverse change in the significance of an archaeological resource ❑ Q ❑ (3 pursuant to ' 15064.5? c) Directly or indirectly destroy a unique paleontological resource or site or unique ❑ ❑ ❑ Q geologic feature? d) Disturb any human remains, including ❑ ❑ ❑ Q those interred outside of formal cemeteries? DISCUSSION: The proposed new construction would replace the residence and writing studio of the late Wallace Stegner, a Pulitzer Prize winning author who owned and resided on the property from 1949 to the time of his death in 1993. Under the proposed Site Development Permit, the existing single family residence and a detached former study/guest cottage would be demolished. The author's writing studio, located adjacent to the north side of the residence, would be preserved and relocated on the property, at the current site of the former study/guest cottage a short distance west of the residence. The Town of Los Altos Hills commissioned two consultants in review of the application. Circa Historic Property Development prepared a Base -Line Historic Resources Assessment and JRP Historical Consulting prepared a Mitigation Analysis and Identification Report. Circa analyzed the property for both the National Registry of Historic Places (NRNP) criteria and the California Registry of Historical Resources (CRHR) and concluded that the writing studio meets the National Register's criteria while the primary residence and guest cottage are contributing buildings. The historical resource on the property includes three contributing components: the main residence, former study/guest cottage, and writing studio. In addition, the rural location and setting contributes to the significance of the resource. While all of these elements contribute the significance of the resource, according to the Circa Assessment, only the writing studio meets the criteria for individual listing in the NRHP and CRHR, as it is most directly associated with the writing career of Stegner. The applicant is proposing to preserve the writing studio and relocate it to the site of the former study/guest cottage west of the main residence on the property. In compliance with the historical resource provisions of CEQA, preservation of the writing studio will be conducted in a manner consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings MITIGATION MEASURE #4: Documentation and Recordation: Documentation and recordation of the main residence, former study/guest cottage, and writing studio shall precede any construction, demolition, or relocation activities. This mitigation measure must be undertaken by a qualified historian / architectural historian (under the Secretary of the Interior's Professional Qualification Standards). Documentation shall follow NPS standards for HABS Historical Report Guidelines, as such standards will ensure the appropriate level of written and photographic recordation of the property's significant historic context and character -defining features. The documentation of the former Stegner property shall approximate HABS Level II documentation and include: a) select existing drawings that would be photographed; b) photographs following the NPS photo policy, of exterior and interior views, along with historic views; and c) written data providing history and description of the property. Additionally, the photographs shall include a view that illustrates the view from the writing studio to help illustrate the setting in which Stegner worked. The Town will retain the documentation for public benefit and copies of the documentation will be offered to interested parties identified during project approval process, particularly all relevant historical organizations as well as organizations and collections dedicated to the work of Wallace Stegner. The Table below includes a list of recipients; however recipients need not be limited to those listed. In addition, the HABS documentation will serve as a baseline of information for the preservation of the writing studio, which will be undertaken as part of the proposed project.

GEOLOGY AND SOILS — Would the project: a) Expose people or structures to potential ❑ ❑ ❑ Q substantial adverse effects, including the risk of loss, injury, or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other ❑ ❑ ❑ Q substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. ii) Strong seismic ground shaking? ❑ Q ❑ ❑ iii) Seismic -related ground failure, including ❑ Q ❑ ❑ liquefaction? iv) Landslides? ❑ ❑ ❑ R1 b) Result in substantial soil erosion or the loss of topsoil? ❑ ❑ ❑ Q c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result mi ❑ ❑ ❑ Q on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or ❑ ❑ ❑ Q propel e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems ❑ ❑ ❑ Q where sewers are not available for the disposal of waste water? DISCUSSION: The applicant has provided a Geotechnical Investigation prepared by Murray Engineers Inc. The Investigation was peer reviewed by the Town of Los Altos Hills' Geotechnical consultant; Cotton, Shires, and Associates. The proposed building site is located 25 to 30 feet from the Monta Vista fault. The project Geotechnical Consultant has recommended the basement be founded on a reinforced mat slab that is a minimum of 10 inches thick Further, the Monta Vista trace is highly sinuous, has a low plane dip angle, and has an uncertain potential for transmitting possible future primary fault rupture. These factors reduce the level of geologic concern about the proximity of the identified fault to the proposed project. MITIGATION MEASURE #5: Geotechnical Plan Review: The project Geotechnical Consultants shall review and approve all geotechnical aspects of the project building and grading plans (i.e. site preparation and grading, site drainage improvements and design parameters for foundations and retaining walls) to ensure that their recommendations have been properly incorporated. • The Project Geotechnical Consultant shall review the proposed energy dissipater placement in the northeastern portion of the property and recommend any appropriate revisions from a geotechnical perspective. The results of the Geotechnical Plan Review shall be summarized by the Geotechnical Consultant in a letter and submitted to the Town Engineer along with other documents for building permit plan check. MITIGATION MEASURE #6: Geotechnical Construction Inspections: The Geotechnical Consultant shall inspect, test (as needed), and approve all geotechnical aspects of the project construction. These inspections shall include, but not necessarily be limited to: site preparation and grading, site surface and subsurface drainage improvements, and excavations for foundations, and retaining walls prior to placement of steel or concrete. At the end of project construction, the consultant shall inspect the completed site drainage improvements to confirm compliance with geotechnical standards. The results of these inspections and the as -built conditions of the project shall be described by the Geotechnical Consultant in a letter and submitted to the Town Engineer for review prior to final inspection.

Since the project seeks discretionary approval of a site development permit as well as zoning, grading, and building permits, protections of the California Environmental Quality Act apply. (Los Altos Hills Code of Ordinances, tit. 10, ch. 2.1303; 2.702(b); 2.402; 2.703(b), 2.1302). Demolitions of the home and study are part of the "whole of the action" being considered for approval, and must be studied along with the other project permits. Since there is ample evidence that this unique site is eligible for listing in the California Register of Historical Resources, we respectfully urge the Town to conduct environmental review that analyzes alternatives to demolition before considering project approval. No CEQA Exemption Applies to the Demolition of the Stegner Property We were alarmed to recently learn that the Town is treating this project as categorically exempt from CEQA under Guideline section 15303. The Town has ample evidence that the Stegner home and study qualify as historic resources under CEQA and are not exempt. Categorical exemptions are rebuttable and "shall not be used for a project which may cause a substantial adverse change in the significance of a historical resource" — or that may have any other potentially significant impact due to its particular circumstances. (CEQA Guideline § 15300.2 (c), (f); Pub. Resources Code § 21084 (e).) Western office 5 Third Street, Suite 707 San Francisco, CA 94103 P 415.947.0692 F 415.947.0699 E -o@nthp.org kMw AK AZ CA, nl, M.

(Pub. Resources Code § 21084. 1.) The "fair argument" standard should apply to the question of whether a resource may be eligible for listing in the California Register. (Architectural Heritage Association v. County of Monterey (2004) 122 Cal.App.4`h 1095.) The standard is met by a fact -based opinion of an historian or an advisory commission that a property qualifies as historic. The fair argument standard triggers an EIR if any substantial evidence in the record — that is, facts or reasonable assumptions/expert opinions based on facts — supports a fair argument that significant impacts may occur, even if a different conclusion may also be well - supported. (Friends of `B"Street v. City of Hayward (1980) 106 Cal.App.3d 988, 1000-1003.) Importantly, if there is a dispute among experts, the Town must defer to the evidence in favor of environmental review. (CEQA Guideline § 15064 (f).) The Historic Significance of the Stegner Home and Study There is significant evidence that the Stegner home and study are historic resources subject to CEQA. Wallace Stegner's importance as a novelist and environmentalist are legendary. We are submitting biographical information about his life and accomplishments. We are informed that last week, on May 15, 2011, the Town's History Committee adopted a resolution recommending that the Stegners' property be added to the Town's Inventory of Historic Sites and Structures. The resolution states in part that designation would recognize "Stegner's substantial work on the committee that initiated the founding of the Town and his contributions as an internationally acclaimed author." There is a very strong case that the Stegner site meets requirements for listing in the Inventory because of its "identification with a person, or persons, who significantly contributed to the culture, history, or development of the Town." (Code of Ordinances, tit. 11, ch. 1.05(b).) From our own research, we know that Wallace and Mary Stegner built their house in the early 1950s. The South Fork Lane property was the only house Stegner ever owned. In a May 2011 article in the San Francisco Chronicle, author Sam Whiting affirmed that " Ulust about every major book that he wrote was written in that study." (Whiting, "Wallace Stegner's Studio Destined for Demolition.") The Stegners collaborated with an architect in the residence design and constructed the landscaping and terrace themselves. Stegner had been one of the first to settle in the Los Altos Hills area, ten years before it became a town: "He bought the property after he was hired as a full professor of English at Stanford in 1945. There was an oak forest and nothing else — no electricity, no road and no water. Stegner did much of the carpentry work himself." The house and study figure in several of Wallace Stegner's books, including All the Little Live Things; A Field Guide to the Western Birds, A Shooting Star, and Spectator Bird. The character Joe Allston, a retired literary agent and protagonist in several of these books, works daily in a study modeled after Stegner's, and both the fictional Joe and the real Wallace looked out at the same Blue Oak and tended to the property as careful stewards of home, hearth, and land. Director Debbie Pedro & Chair James Abraham May 27, 2011 Page 3 of 3 The Stegner home and study amply meet the Town's own criteria for designating local landmarks, as well as the objective criteria for listing in the California Register and the National Register of Historic Places. CEQA requires that the Town fairly evaluate this special environmental setting as a basis for determining the required level of environmental review. It clearly has not yet done so, and its approval of demolition on such an inadequate record would be a disservice to the cultural heritage of the Town and to the State of California, and inconsistent with the mandates of state law. Conclusion Wallace Stegner contributed immensely to the history of the Town of Los Altos Hills. His legacy as an internationally -revered novelist and environmentalist, including as the Pulitzer Prize-winning author of Angle of Repose and the recipient of the National Book Award for The Spectator Bird, is further enhanced by his long and fruitful association with literary education at Stanford. The unique location and setting of the Stegner residence and study provided him with serene tranquility and a place of inspiration. Accordingly, we ask that the Planning Commission decline to consider the demolition of the home and study of this remarkable man pending completion of a full CEQA review to consider feasible mitigation measures and alternatives to demolition. Thank you for your consideration. We would be most willing to meet with you to discuss this matter further and to assist in any way we can. Please do not hesitate to contact us at 415-947-0692.

The property is the former property of noted writer Wallace Stegner, and his wife Mary Stuart Page Stegner. Construction of the residence was completed in 1949 making it 62 years old. Per the California Environmental Quality Act (CEQA), a property over fifty years of age that is proposed to be altered in any way (including demolition or relocation) it will require a Base -Line Historic Resources Assessment report to evaluate the subject property for historic significance. Development of the historical evaluation (which includes assessment of integrity as defined by the National Register Criteria for Evaluation) and a limited historic context statement is consistent with the requirements of CEQA. The Assessment report provides the minimum required to determine what buildings, structures and objects contribute to the historic significance of the. property only. As a result of a review of the Findings of the Assessment it may be determined that mitigation measures are needed in order to lessen the impact of the proposed project. DESCRIPTION OF PHYSICAL CHARACTER DEFINING ELEMENTS The Secretary of the Interior's Standards for the Treatment of Historic Properties recognizes that every building has "... its own identity and its own distinctive character. Character refers to all those visual aspects and physical features that comprise the appearance of every historic building. Character -defining elements include the overall shape of the building, its materials, craftsmanship, decorative details, interior spaces and features, as well as the various aspects of its site and environment. "'- The retention of these characteristics directly affects the property's ability to communicate its historic significance. The characteristics of 13456 South Fork Lane are identified below and are discussed in the Evaluation Section under Integrity. Main Residence (1949): The single -story residence is generally a L -plan with an attached carport and a continuous flat roof plain with deep, closed eaves. The central flat roof area (over the interior living room space) is "popped -up" I U.S. Department of the Interior, National Park Service.

The dining room was slightly enlarged (4'x12') in 1968. The recessed entry is located at the northeast elevation. A deep, wood and paved brick deck is cantilevered off the west elevation is visually connected to the residence by a "window -wall" and double glass doors. A covered breezeway connects the residence to the carport. A concrete "Gunnite" and rile pool (1979) is located off the eastern most elevation of the residence. Solar panels and heating system were also installed in 1979. Former Study/Guest Cottage (c. 1949): The single -story former study/guest cottage is a L -plan with board -and -batten wood siding and flat roof, over -sized wood frame windows on the south elevation and full-length wood frame windows on the north elevation. There is a grade level entry porch with wood post. The cottage (or cabin as it is sometimes referred to) is located down-slope (west) and described as a "...short distance below the main residence...that Wally had originally built [emphasis added] as his study. Studio (post 1952 -pre -1968): The single -story studio is similar to the residence in wall material and flat roof design. It has metal frame clearstory windows on three elevations with glass sliding doors on the west elevation, connecting to the wooden deck area. Planter boxes divide the space between the two deck areas. No plans were uncovered for the studio building itself, however, the studio is shown on plans of 1968. Location and Setting: The residential cluster (residence, studio and guest house) of 13456 South Fork Lane is sited on just under 2.5 acres of wooded land in the town of Los Altos Hills (the Town). The lot was originally 5 acres and was divided about 1974. The Town is located approximately thirty-five miles south of San Francisco, five miles south of Stanford University and seventeen miles north of downtown San Jose. The community has maintained a decidedly rural environment that continues and preserves the historic landscape of the foothills. The over characteristic of the subject property at 13456 South Fork Lane is rural in nature, with a gently undulating terrain enhanced with mature trees and low plantings. Rustic pathways lead to terraces that surround the residence and studio buildings. Expansive views of the surrounding foothills are seen from the buildings, terraces, walkways and decks. A winding road leads to the private drive atop the foothill. Neighboring residences are generally hidden from view due to the surrounding private, heavily wooded acreage. HISTORICAL BACKGROUND/CONTEXT Los Altos Hills The following brief historical overview is quoted from the City of Los Altos Hills' website, on the page titled "Town History." Ohlone Indians were the first known residents of Los Altos Hills. They were part of a group of Native Americans who once inhabited small villages throughout the Santa Clara Valley. Both Los 3 Phillip L. Fradkin, Wallace Stegner and the American West, (New York Alfred A. Knoff, 2008),119. 582 Market Street, Suite 1800, San Francisco, CA 94104, p. 415.362.7711 CIRCAHisroric Property Development Altos and Los Altos Hills have been substantiated as sites of early Ohlone villages. In 1955, Indian remains and artifacts such as mortars and pestles were found on the Peck property east of Moody Road. In 1964, developers on O'Keefe Lane unearthed more human remains and artifacts. Still later, in 1970, an Ohlone village and burial ground of major significance came to light on the Costello property on O'Keefe Lane, prompting archaeological study by Foothill College and others. Additional mounds and village sites have since been excavated along Permanente and Matadero Creeks. Following roughly the path of today's Fremont Road, Juan Bautista De Anza passed through what was to become Los Altos Hills while making his journey from Monterey to San Francisco in 1776 to establish the Presidio. A year later, the Santa Clara Mission was founded. Two large Spanish -Mexican land grants comprise Los Altos Hills: Rancho La Purissima Concepcion, 4,436 acres granted to Native Americans Jose Gorgonio and his son Jose Ramon in 1840 and sold to Juana Briones de Miranda in 1844 for the sum of $300; and Rancho San Antonio, 4,438 acres granted to Juan Prado Mesa. Adobe Creek was the boundary line of the two ranchos. The Briones and Mesa families were friendly and became related when two of the Mesa men married two of the Briones women. In 1855 Juana Briones sold 3,000 acres to Martin Murphy, founder of the City of Sunnyvale, who had previously leased her land for cattle grazing. Murphy gave 2,800 acres to his daughter, Elizabeth Yuba, when she married William Taaffe, a prosperous San Francisco merchant. They built a home on what is now the Foothill Community College campus and had four children: William, Martin, and twin daughters Mary and Mathilda. Some of the Taaffe descendants still reside in Los Altos Hills. The two large ranchos were eventually parceled and sold as smaller ranches for cattle grazing and vineyards, mostly of Zinfandel grapes. Many Italian and French vintners lived on Purssima Road until a blight destroyed the vineyards near the turn of the century. Soon after, orchards of apricots, plums and prunes flourished. With its millions of fruit trees producing a beautiful, aromatic sea of blossoms, Santa Clara Valley became the "Valley of Heart's Delight" and so it remained well into the 1960s. Trains and tour buses brought countless travelers from near and far to glimpse this unique panorama. Wealthy San Franciscans attracted to the area during this period built summer estates in Los Altos Hills. Among the many still standing are: The Shumate House on Viscaino, the Lohman and Griffin Houses on the Foothill College campus, the Morgan Manor (which for many years was operated as Ford Country Day School) on Stonebrook, and the Finn Mansion on Prospect. Both Morgan Manor and Griffin House are official Town Historical Landmarks. The Town of Los Altos Hills was incorporated on January 27, 1956. Before then, residential development was constrained by numerous factors, including lack of a dependable water supply. Water from wells and creek beds was safe, but not always adequate. Headwaters for Hale, Adobe, Barron, Matadero, Purissima, and Deer Creeks are generated in local foothills characterized by heavily wooded banks and often -impenetrable areas of poison oak and chaparral. Homes and farms were usually on large acreage. The overall personality of the region was distinctly rural. In 1956, the many advocates for incorporating the City, to be known as "The Town of Los Altos Hills", were singularly dedicated to "preservation of the rural atmosphere of the foothills." 582 Market Street, Suite 1800, San Francisco, CA 94104, p. 415.362.7711 i CIRCAHisroric Property Deveiopmenr While many changes have taken place in the intervening years, most of the pleasant country aspects of the Town remain as new housing is constructed to accommodate the needs and lifestyles of today's residents. Wallace Stegner Born on February 18, 1909 in Lake Mills, Iowa, Wallace Earle Stegner was the second of two sons born to George and Hilda Paulson Stegner. Following the restless patriarch, the family moved frequently during Wallace's youth, settling finally in Salt Lake City where he attended East High School. Shortly thereafter, Wallace completed his undergraduate studies at the University of Utah and went on to earn his master's degree (1932) and a Ph. D. in American Literature (1935) from the University of Iowa.' Wallace married Mary Stuart Page in 1934. He published his first novel, Remembering Laughter, in 1937, and with it won the Little, Brown -Publishing Company prize and $2,500. With this success he was able to gain a teaching position at Harvard where he taught from 1939 to 1945.5 Stegner produced several novels over the next few years including On a Darkling Plain (1940), Fire and Ice (1941), and Mormon Country (1942), but none were as successful as his first novel until the publication of The Big Rock Candy Mountain in 1943. Largely autobiographical, this book documents the family's travels throughout the American and Canadian West and the character Bo is based on Stegner's own father.b Following World War 11, Stegner accepted a position at Stanford University in the creative writing department. He would be in charge of the program and was told that the university wanted to expand the program and raise its stature, a task he was especially qualified for after his experiences at Iowa and Harvard.' Wallace and Mary arrived in June 1945 and began looking for property on which to build what would turn out to be their fust and last year-round home.' They eventually settled on a hilltop "with a magnificent view of the peninsula foothills between Stanford and the ocean in what later became Los Altos Hills."' The Stanford Creative Writing Program, founded by Stegner in 1946, became one of the most highly ranked writing programs in the county. As his son Page Stegner states in his introduction to Wallace Stegner's West, "As much as anything it is that writing program that identifies him with the state [of California] and its contribution to literary culture.i10 Under the 25 years of his leadership the program became "a virtual Who's Who of contemporary American writers," boasting such writers as Eugene Burdick, Tillie Olsen, Max Apple, Larry McMurtry, Robert Stone, Ken Kesey, Ed McClanahan, Nancy Packer, Ernest Gaines, Robert Haas, Wendell Berry, Edward Abbey and N. Scott Momaday." Peter Collier of Audubon magazine considered Stegner to be "the leading teacher of writing in his generation." 12 4 Wallace Stegner's West/ Edited with an Introduction by Page Stegner.

Wallace and Mary had always been socially and politically active, and advocated for a number of interests dedicated to environmental causes. In 1945 he published the nonfiction work entitled "One Nation," which spoke to the corrosive effects of racial prejudice in the United States. This work was a co -winner of the Anisfeld- Wolfe Award for the best book of the year on race relations." In 1955 he published This Is Dinosaur, which helped in the campaign to save the Dinosaur National Monument in Colorado and Utah from flooding behind proposed dams on the nearby Green River. Perhaps his most well-known environmental contribution was his famous Wilderness Letter, delivered to Davis Pesonen of the University of California's Wildlands Research Center, which argued for the preservation of wilderness as a spiritual resource for the American people. The sentiments expressed in this letter "became a mission statement harked by conservationists around the world, despite its distinctly American references .,,14 The letter was also used to introduce the bill that established the National Wilderness Preservation System in 1964.1-, Stegner retired from Stanford in 1971 to devote more time to writing. He won the Pulitzer Prize in 1972 for Angle of Repose, which is widely considered to be his masterpiece work. In addition to his achievements at Stanford and in the environmental world, Stegner was named a Guggenheim Fellow twice (1949 and 1959); received a Rockefeller fellowship to teach in the Far East in 1950-1951; was awarded a fellowship from the Center for Advanced studies in the Behavioral Sciences in 1956; received honorary doctorates from the University of Montana and Middlebury College, and the first Robert Kirsh Award for Life Achievement from the Los Angeles Times. 16 He received the John Muir award from the Sierra Club for his contributions to conservation, the Governor's Award for the Arts from the California Arts Council, and the Cyril Magnin Award for Outstanding Achievement in the Arts. 13456 South Fork Lane When the Stegners purchased the Los Altos Hills property in the late 1940s the area was still largely undeveloped. There was no nearby electricity, no road or water, and no sewer connection available. Though his position at Stanford allowed him to work half-time for a full-time salary, Stegner had to complete much of the finishing work and all of the landscaping work himself in order to afford the house. 17 The Stegners also received help from students who built the bookcases and gave them to the family as a gift. Construction was completed in 1949. Once completed, the house was featured in the August 1952 issue of House and Garden, which describes the house as having been built "for a writer, his musical wife, and their 15 -year-old son.s1.. The article describes the house: The living area is actually one big room, resourcefully divided by low partitions and skillfully - placed furniture into separate centers for dining, music, study, [and] conversation. The dividers keep the open feeling while they screen off each area. The son's bedroom and bath are arranged like a separate apartment with its own private entry. 13 William H.

Plantings are used at the window wall to help bring an out- of-doors spirit into [the] house all year long.19 In Wallace Stegner and the American West, the author writes that the house was "best described as Bay Area modern in the style of a Joseph Eichler or as a William W. Wurster -type home set in splendid isolation rather than among the many Palo Alto look-alikes on the flats below Los Altos Hills."20 Another description states that the house "blended quietly into its surroundings with a low -slung, Frank Lloyd Wright sensibility."21 Its broad exterior deck overlooked the undeveloped hills beyond and provided a spectacular setting for the many dinner parties and other events hosted at the house. Though Stegner took much of the physical labor upon himself, the house itself was designed by architects Bolton White and Jack Hermann; the landscape was designed by Eckbo, Royston & Williams.22 Jack Hermann studies architecture at the University of California, Berkeley, and established a partnership with architect Bolton White in 1948. Together they designed hospitals, clinics, churches, offices, housing, stores and recreation centers. Charles White was a designer in the architecture office of Gardner Dailey from 1936-1942, an influence that clearly shows in the property's modem design. Adjacent to the main house was Stegner's writing studio. Books lined the walls and "the manual typewriter was placed so that Wally wasn't districted by the view."" The studio is set next to a rare blue oak tree that Stegner is said to have treasured.'-' A short distance from the residence and writing studio was a small board -and -batten cottage that Stegner originally used as his study. Later, Stegner's son Page and his wife and baby occupied the cabin while Page was in graduate school at Stanford. Other residents followed including other family members, students, instructors, and the young couple fictionalized in Stegner's All the Little Live Things. Mary and Wallace established their estate on the hill ten years before Los Altos Hills became a town and battled against the development that would come to surround them in the last half of the 20'b century. This house was their only full-time residence and the couple resided here for over fifty years. Stegner last saw the house in March 1993 when he went to Santa Fe to deliver a lecture. While there he was involved in a severe car accident and sustained fatal injuries. Wallace Stegner died from injury -related complications on April 13, 1993. He was 84 years old EVALUATIVE FRAMEWORK The National Register Criteria for Evaluation The National Register is the nation's master inventory of known historic resources. It is administered by the National Park Service (NPS) in conjunction with SHPO. The National Register includes listings of buildings, structures, sites, objects, and districts that possess historic, architectural, engineering, 19 [bid. zo Phillip L.

The National Register criteria and associated definitions are outlined in National Register Bulletin Number 15: How to Apply the National Register Criteria for Evaluation. The following is a summary of Bulletin 15: Criteria Generally, resources (structures, sites, buildings, districts and objects) over 50 years of age can be listed in the National Register provided that they meet the evaluative criteria described below. Resources can be listed individually in the National Register or as contributors26 to an historic district. The National Register criteria are as follows: A. Resources that are associated with events that have made a significant contribution to the broad patterns of history; B. Resources that are associated with the lives of persons significant in our past; C. Resources that embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or D. Resources that have yielded or may likely yield information important in prehistory or history. Historic Districts: According to National Register Bulletin 15, a historic district "possesses a significant concentration, linkage, or continuity of sites, buildings, structures, or objects united historically or aesthetically by plan or physical development s26 Examples of districts include: • business districts • canal systems • college campuses • agricultural properties with large acreage/numerous properties • industrial complexes • residential area • transportation networks California Register of Historical Resources (CRHR) The California Register program encourages public recognition and protection of resources of architectural, historical, archeological and cultural significance, identifies historical resources for state and local planning purposes, determines eligibility for state historic preservation grant funding and affords certain protections under the California Environmental Quality Act n u A "contributor" is a building, site, structure, or object that adds to the historic associations or historic architectural qualities for which a property is significant. The contributor was present during the period of significance, relates to the documented significance of the property, and possesses historic integrity or provides important information about a period; or the contributor independently meets National Register criteria. A "non -contributor" does not add to the historic associations or historic architectural qualities as it was not present during the period of significance; it has experienced alterations, disturbances, additions, or other changes; or it does not independently meet the National Register criteria. VCA Office of Historic Preservation website: http://www.ohp.parks.ca.gov/?page id=21238. 582 Market Street, Suite 1800, San Francisco, CA 94104, p. 415.362.7711 CIRCAHbitaric Pre+perry Development Criteria To be potentially eligible for individual listing on the CRHR, a structure must usually be more than 50 years. old, must have historical significance, and must retain its physical integrity. In terms of historic significance, the California Register of Historical Resources evaluates a resource based on the following four criteria: • Criterion 1 (Event): Resources associated with events that have made a significant contribution to the broad patterns of local or regional history, or the cultural heritage of California or the United States. • Criterion 2 (Person): Resources associated with the lives of persons important to local, California or national history. • Criterion 3 (Desi--n/Construction): Resources that embody the distinctive characteristics of a type, period, region or method of construction, or that represent the work of a master or possess high artistic values. • Criterion 4 (Information Potential): Resources that have yielded or have the potential to yield information important to the prehistory or history of the local area, California or the nation. Integrity Integrity is the measure by which properties are evaluated. To retain integrity a property must have most of the seven aspects of integrity as defined by the National Register Criteria for Evaluation. The seven aspects of integrity are quoted as follows: • Location - Location is the place where the historic property was constructed or the place where the historic event occurred. • Desien - Design is the combination of elements that create the form, plan, space, structure, and style of a property. • Setting - Setting is the physical environment of the historic property. • Materials - Materials are the physical elements that were combined or deposited during a particular period of time and in a particular pattern or configuration form a historic property. • Workmanship - Workmanship is the physical evidence of the crafts of a particular culture or people during any given period in history or prehistory. • Feeling - Feeling is a property's expression of the aesthetic or historic sense of a particular period of time. • Association — Association is the direct link between an important historic event or person and a historic property. According to the Office of Historic Preservation's Technical Assistance Series Bulletin #6: 582 Market Street, Suite 1800, San Francisco, CA 94104, p. 415.362.7711 CIRCAHIsroric Properry Development Integrity is the authenticity of an historical resource's physical identity evidenced by the survival of characteristics that existed during the resource's period of significance. Historical resources eligible for listing in the California Register must meet one of the criteria of significance described above and retain enough of their historic character or appearance to be recognizable as historical resources and to convey the reasons for their significance. It is possible that historical resources may not retain sufficient integrity to meet the criteria for listing in the National Register, but they may still be eligible for listing in the California Register.' EVALUATION National Register of Historic Places (NRHP) Criterion A (Associative Value - Event): To be considered for listing under Criterion A, a property must be associated with one or more events important within a defined historic context. Criterion A recognizes properties associated with single events, such as the founding of a town, or with a pattern of events, repeated activities or historic trends, such as the gradual rise of a port city's prominence in trade and commerce. The event or trends, however, must clearly be important within the associated context: settlement, in the case of the town, or development of a maritime economy, in the case of the port city. Moreover, the property must have an important association with the event or historic trends, and it must retain historic integrity.' Historical research did not reveal that the property at 13456 South Fork Lane is notably associated with an important event or pattern of events related to national state or local history. The former Stegner property was developed in the late 1940s (before the incorporation of the Town) however, no documentation revealed that it was directly associated to the early development and/or planning of the Town of Los Altos Hills. Though the property was the site of the writings of Wallace Stegner the significance of those events are more closely related to the property's association with Stegner himself. As such, the property at 13456 South Fork Lane does not appear to be potentially eligible for the National Register of Historic Places under Criterion A. Criterion B (Associative Value - Person): Properties may be eligible for the National Register if they are associated with the lives of persons significant in our past. According to National Register Bulletin 15, persons "significant in our past" refers to individuals whose activities are demonstrably important within a local, State, or national historic context. Properties eligible under this criterion are usually those associated with a person's productive life, reflecting the time period when he or she achieved significance. The best representatives usually are properties associated with the person's adult or productive life.30 The property at 13456 South Fork Lane is significant for it's association with Wallace Stegner, whose significance as an American writer has influenced an international breadth of writers and environmentalists during the middle part of the 20`h century. Mr. Stegner was a notable power for his time and won many awards including the following: All in all Stegner won multiple, renowned awards and grants, including: • 1937 Little Brown Prize = Remembering Laughter ' Office of Historic Preservation, Department of Parks and Recreation.

Henry Awards (for magazine stories), was twice a Guggenheim Fellow (1949 and 1959), Senior Fellow of the National Institute of Humanities, and was a member of the National Institute and American Academy of Arts and Letters, member National Academy of Arts and Sciences. As an environmentalist he was special assistant to former Interior Secretary Stewart Udall (during the Kennedy Administration). He also served on and then chaired the Advisory Board for National Parks, Historical Sites, Buildings, and Monuments. According to National Register Bulletin 15, "Each property associated with an important individual should be compared to other associated properties to identify those that best represent the person's historic contributions." This house was their "...first and last..."" full-time residence and the couple resided here for over fifty years. Wallace Stegner occupied the subject property from 1949 - 1994 and the Stegner family remained on the property until its recent sale to the Yong family. The property appears to be potentially eligible for the National Register under Criterion B for its long-term association with Wallace Stegner. Criterion C (Desi--n/Construction): This criterion applies to properties significant for their physical design or construction, including such elements as architecture, landscape architecture, engineering, and artwork. To be eligible under Criterion C, a property must meet at least one of the following requirements: • Embody distinctive characteristics of a type, period, or method of construction. • Represent the work of a master. ® Possess high artistic value. • Represent a significant and distinguishable entity whose components may lack individual distinction. The first requirement, that properties "embody the distinctive characteristics of a type, period, or method of construction," refers to the way in which a property was conceived, designed, or fabricated by a people or culture in past periods of history. "The work of a master" refers to the technical or aesthetic " Phillip L. Fradkin, Wallace Stegner and the American West, 117. 582 Market Street, Suite 1800, San Francisco, CA 94104, p. 415.362.7711 CIRCAHisrodir Property Deye(op"tenr achievements of an architect or craftsman. "High artistic values" concerns the expression of aesthetic ideals or preferences and applies to aesthetic achievement." The residence at 13456 South Fork Lane was designed by architects Bolton White and Jack Hermann and the landscape was designed by Eckbo, Royston & Williams. As noted in the property history description above the style of the house appears to have been inspired by the styles of Eichler or Wurster, and nestled into the natural landscape. This design was important enough to secure a place in the iconic arbiter of taste: House and Garden magazine. However, the house design itself cannot be attributed to being a significant influence of architecture in the region or elsewhere. It is unknown who designed the writing studio but was not included in the White and Hermann design. Under this criterion, the subject property does not appear potentially eligible for the National Register under Criterion C. Criterion D (Information Value): Criterion D most commonly applies to properties that contain or are likely to contain information bearing on an important archeological research question. The research conducted for this review provided no indication that the property at 13456 South Fork Lane may provide important archaeological information. Therefore, the property does not appear to be potentially eligible as an individual resource under Criterion D. District discussion The National Park Service defines a historic district as "a geographically definable area... possessing a significant concentration... [of] buildings, structures, or objects united by past events or aesthetically by plan or physical development." Research indicates that the remaining swimming pool (1979) and gardening shed were not part of the original design plans for the property. As such, they are not united aesthetically by plan or physical development and cannot be considered contributors to a historic district. While they are components of the larger estate and do not detract from the integrity or significance of the residence, studio and guesthouse, these elements are not directly associated to the designed features for which the property is significant. Therefore, only the residence, studio and guesthouse are considered contributing historic resources within the existing setting; no larger historic district is present. California Register of Historical Resources (CRHR) Criterion 1 (Events) For the reasons stated above under Criterion A of the National Register, the property at 13456 South Fork Lane does not appear to be potentially eligible for the California Register as an individual resource under Criterion 1.

Criterion 4 (Information Potential) For the reasons stated above under Criterion D of the National Register, the property at 13456 South Fork Lane does not appear to be potentially eligible for the California Register as an individual resource under Criterion 4. Integrity To retain integrity a property must have most of the seven aspects of integrity as defined by the National Register. The property retains a high degree of integrity as discussed below. Location The property remains in the original location where it was constructed and therefore retains integrity of location. Design — Although the important interior character defining features of the studio (wood paneling and shelves) have been removed and walled in sheet rock the subject property (residence, studio and guest house) retains its original form, plan, spatial organization, structure, and style. Therefore the property retains integrity of design. Setting With exception of the construction of Interstate 280 in 1955, the immediate physical setting of the property remains much the same as it was when originally developed33. As such, the property retains integrity of setting. Materials Few exterior alterations appear to have been made to the property since originally constructed. It is assumed that minor repairs/adjustments and on-going maintenance were executed over the years. Permits were issued for the dining room addition (1968), pool and solar panels/heating (1979) and re -roofing (1999). Exterior materials do not appear to have been significantly altered and all appear to be in excellent condition. Some deterioration or change may have taken place in the landscape plantings over time but the hardscape elements (walkways) are still apparent. The property retains a high degree of material integrity. Workmanship Workmanship is important because it can furnish evidence of the technology of a craft, illustrate the aesthetic principles of a historic or prehistoric period, and reveal individual, local, regional, or national applications of both technological practices and aesthetic principles. Feeling The presence of physical features (house, landscape, topography, circulation patterns and materials), when taken together, convey the property's historic character and thus the property demonstrates integrity of feeling. 33 Period photograph from 1949.

His novels and short stories are beloved by generations. Over the course of his publishing career (about 53 years) Stegner published thirteen novels, three short -story collections, and sixteen nonfiction pieces, edited eighteen works, and received multiple awards and honors. In addition, Mr. Stegner was a prominent figure at Stanford University. Overall, the property appears to be in good condition and retains a high degree of historic integrity in all of its significant components. Local Register (Town of Los Altos Hills) The Town of Los Altos Hills has not officially reviewed or adopted the property at 13456 South Fork Lane as a historic resource34 SUN IARY Circa: Historic Property Development finds that the property at 13456 South Fork Lane meets the National Register criteria for a historic district comprised solely of the cluster of buildings - residence, studio and guesthouse - as contributing buildings to a district. Individually the only building that meets the NR criteria would be Stegner's writing studio. Therefore eligibility for the National Register makes the property automatically eligible for the California Register35. Respectfully submitted, Sheila McElroy Principal Circa: Historic Property Development 34 Some members of the Town of Los Altos Hills History Committee did meet in May 2011 to discuss the possibility of adding the Stegner property to the Town's Inventory of Historic Sites, however, no official action was taken at that time. 35 Per the Public Resources Code Section 5020.1q and State CEQA Guidelines Section 15064.5 (b)(1) and (2) all National Register -listed or eligible resources qualify for listing in the California Register. 582 Madket Street, Suite 1800, San Francisco, CA 94104, p. 415.362.7711 CIRCAHistoric Property Dereiapmenr BIBLIOGRAPHY Books Wallace Stegner's West/ Edited with an Introduction by Page Stegner.

Cover Photograph: 13456 South Fork Lane, Los Altos Hills, camera facing east 8 - - -- _-.. __ IVE SUIVIM[ARY The Town of Los Altos Hills (Town) is reviewing an application for a Site Development Permit for the property at 13456 South Fork Lane, Los Altos Hills, Santa Clara County, California. The proposed project includes construction of a 7,337 square foot new residence with a 3,647 square foot basement and attached secondary dwelling unit, as well as a re -graded driveway and new 240 square foot swimming pool. The proposed new construction would replace the residence and writing studio of the late Wallace Stegner, an esteemed American author who owned and resided in the property from 1949 to the time of his death in 1993. Under the proposed Site Development Permit, the former Stegner residence and an associated former study/guest cottage would be demolished. The author's writing studio, located adjacent to the north side of the residence, would be preserved and relocated on the property, at the current site of the former study/guest cottage a short distance west of the residence. The issuance of the Site Development Permit for the project qualifies as a discretionary action by the Town and thus provisions of the California Environmental Quality Act (CEQA) apply, specifically CEQA Guidelines, Title 14 California Code of Regulations Section 15064.5 and California Public Resources Code (PRC) Section 21084.1. As per CEQA Guidelines Section 15064.5(a), the Town has determined that the property is an historical resource for the purposes of CEQA because of its important and direct association with the productive life of the acclaimed American author Wallace Stegner. This determination is supported by a Base Line Historic Resources Assessment (Assessment) undertaken by CIRCA Historic Property Development (CIRCA) on behalf of the Town in November 2011. The CIRCA report concluded that the subject property is eligible for listing in the California Register of Historical Resources (CRHR) and National Register of Historic Places (NRNP) under Criterion 2 and Criterion B for its association with Wallace Stegner.I Following this determination, the Town hired JRP Historical Consulting, LLC (JRP) to prepare this Historical Resources Mitigation Analysis and Identification Report to provide analysis, and identify feasible mitigation measures to avoid or reduce impacts to the historical resource, pursuant to the requirements of CEQA. JRP concludes that under CEQA Guidelines Section 15064.5(b) the issuance of the Site Development Permit may cause a substantial adverse change to the subject historical resource because the proposed project would materially impair contributing elements of the resource through demolition. As per PRC Section 21084.1, a project that may cause a substantial adverse change to a historical resource is a project that may have a significant effect on the environment. As such, this report identifies feasible measures to mitigate the significant adverse changes associated with the project.2 The report includes an 1 CIRCA Historic Property Development, Base -Line Historic Resources Assessment. 13456 South Fork Lane, Los Altos Hills, CA, November 2011.

ON 2. ANALYSIS OF PREVIOUS DOCUMENTATION In November 2011, the Town commissioned CIRCA to prepare an Assessment of the historical status of the property at 13456 South Fork Lane. This Assessment was undertaken in compliance with CEQA, which requires that a lead agency determine whether a resource may be a historical resource. Although the property was not — and is not — listed in the CRHR, Los Altos Hills Inventory of Historic Sites and Structures, or NRHP, under CEQA this does not preclude a lead agency from determining whether the resource qualifies as a historical resource.4 The property is illustrated in the cover photograph and the photograph below. l:ormer Wallace Stegner, Residence, camera facing west. Posts and orange netting indicate the general size and form of the proposed replacement residence. The Assessment included a description of the property, historical background/context, evaluative framework, CRHR/NRHP evaluation of the property, and identification of the property's character -defining features. CIRCA concluded that the former Stegner property constitutes a historic district, significant under CRHR Criterion 2 and NRNP Criterion B for its association with Wallace Stegner. The main residence, writing studio, and former study/guest cottage are considered contributors to the district. Furthermore, the evaluation concluded that only the writing studio, illustrated below, is significant as an individually eligible property because, of the buildings on the property, it is most associated with the significant writing career of Stegner.5 4 CEQA Guidelines 15064.5(a) and PRC 21084.1. 5 While the CIRCA Assessment concluded that the property appeared eligible for listing in the CRHR /NRNP as a historic district, it is possible that the property could also be considered an individual historical resource that includes three contributing elements: the Stegner residence, former study/guest cottage, and writing studio. Evaluating the property as an individual resource with multiple components would not alter the conclusions of the Assessment, which concluded that the property is a historical resource for the purposes of CEQA. Also, CIRCA did Writing Studio of the late Wallace Stegner, camera facing southeast. (Photo courtesy of Town of Los Altos Hills.) Writing Studio of the late Wallace Stegner, camera facing north. not produce a DPR 523 form for the property. While use of DPR 523 forms for recordation of historic resources is standard practice, it is not a regulatory requirement under CEQA and is not specifically necessary in order to establish the historic status of a property. 0 3 • The findings of the Assessment support the Town's determination that the property qualifies as a historical resource for the purposes of CEQA. The Assessment included discussion of the property's historic context and character -defining features, and included an adequate evaluation under appropriate CRHR and NRNP criteria. The report did not provide analysis under CEQA Guidelines 15064.5(b) regarding the project's potential to cause a substantial adverse change to the historical resource, however. This analysis, along with the identification of feasible and appropriate mitigation measures under CEQA Guidelines 15064.5(b)(4) is provided herein. 3. IDENTIFICATION OF APPROPRIATE MITIGATION MEASURES 3.1. DISCUSSION OF IMPACTS As discussed in Section 2, the Stegner House historical resource includes three contributing components: the main residence, former study/guest cottage, and writing studio. In addition, the rural location and setting contributes to the significance of the resource. While all of these elements contribute the significance of the resource, according to the Assessment, only the writing studio appears to meet the criteria for individual listing in the NRHP and CRHR, as it is most directly associated with the writing career of Stegner. Under the proposed Site Development Permit, both the main residence and former study/guest cottage would be demolished. As such, the action would constitute a substantial adverse change to the historical resource as a whole because these elements of the historical resource would be materially impaired as defined in CEQA Guidelines Section 15064.5(b)(1)-(2), such that they would be unable to convey significance under the CRHR. While the proposed project would cause a substantial adverse change to the main residence and former study/guest cottage, this analysis concludes that it would not cause a substantial adverse change to the writing studio. Under the proposed project, the Stegner writing studio would be preserved and relocated to the current location of the former study/guest cottage, which is located a short distance west of (and at a lower elevation to) the main residence. It may be infeasible, however, to move the writing studio's bathroom and storage extension, which was added to the building, because — according to the project proponent — the extension may not have sufficient structural soundness to be successfully moved and there may be inadequate capacity in the property's septic system to allow for the additional bathroom at the new location. Preservation of the building is intended be conducted in a manner consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings. Under CEQA, such treatment is generally considered to mitigate a project's impacts below a level that is considered significant.6 If undertaken through fully enforceable permit conditions, the proposed action, in conjunction with the documentation mitigation measure, discussed below, could help the project be mitigated to a level that is less than significant under CEQA. While relocating a historical resource is generally discouraged under the CRHR, the regulations recognize that if a building is moved to prevent its demolition at its former location and if the new location is compatible with the original character and use of the historical resource, that the resource will still convey significance under the CRHR. Under this CRHR Special 6 CEQA Guidelines Section 15126.4(b)(1)-(2) C-1 e Consideration, a historical resource must retain its historic features and compatibility in orientation, setting, and general environment. Under the proposed project, these Special Considerations are met, as the project will preserve the character -defining features of the building and the general rural residential location and setting that is associated with Wallace Stegner's use of the building.7 The writing studio will be moved onto the concrete slab foundation of the former study/guest cottage, shown below, preserving the building's orientation to the adjacent landscape and providing the historical resource a nearly identical setting and general environment as it currently has. Although the writing studio's new location will not have the physical relationship with the original house, this aspect of its setting is of less importance to the building's significance as it relates to Stegner's writing career. The building's hillside, rural, and remote orientation and setting with views of the adjacent landscape will be preserved. Former study/guest cottage, camera facing west. Writing studio will be moved to this location under proposed project. In order to comply with the historical resource provisions of CEQA, however, preservation of the building would need to be conducted in a manner consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings. Preservation is the most appropriate treatment, and is detailed below: Preservation is defined as the act or process of applying measures necessary to sustain the existing form, integrity, and materials of an historic property. Work, including preliminary measures to protect and stabilize the property, generally focuses upon the ongoing maintenance and repair of historic materials and 7 California Code of Regulations Title 14 Section 4852; CIRCA Historic Property Development, Base -Line Historic Resources Assessment: 13456 South Fork Lane, Los Altos Hills, CA, November 2011. 7 features rather than extensive replacement and new construction. New exterior additions are not within the scope of this treatment; however, the limited and sensitive upgrading of mechanical, electrical, and plumbing systems and other code -required work to make properties functional is appropriate within a preservation project.$ Preservation would retain character -defining features from the period of Stegner's writing studio use and allow this portion of property to continue to convey significance through integrity of its physical features.9 The Assessment did not provide details regarding the writing studio's specific character -defining features, including the origins of the building's extension at the southeast corner. This extension is not shown on the building's original plans, and it is unclear whether it dates to the building's period of significance. The Town does not have any permit records for the bathroom and storage extension. Stegner may have used this portion of the building during his writing career, but it seems unlikely to have the same level of importance as the main writing studio. Furthermore, there is no indication that any of Stegner's original furniture or belonging that were in the writing studio are extant at the property and the Assessment states that interior wood paneling and shelves have been removed. Remaining interior finishes and features from the historical resource's period of significance should be retained and moved with the building. 10 Moving, and any interim storage, of the writing studio would need to follow appropriate guidance in order to best protect all the building's structural systems and design features. All work should be undertaken by a qualified structural mover with extensive experience in the relocation of historic buildings. The relocation should follow applicable National Park Service (NPS) guidance for historic structures, including Moving Historic Buildings, which details appropriate relocation practices. While this report does not undertake a full feasibility study of relocation, as a modestly -sized wood frame building of relatively modern construction, it appears that the writing studio could be moved to the new onsite location without causing damage to or destruction of the building.l i e Kay D. Weeks and Anne E. Grimmer, The Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidance for Preserving, Rehabilitation, Restoring, and Reconstructing Historic Buildings (Washington, D.C.: National -Parks Service, Heritage Preservation Services, 1995), 61. 9 CEQA Guidelines Section 15126.4. 10 CIRCA Historic Property Development Base -Line Historic Resources Assessment: 13456 South Fork Lane, Los Altos Hills, CA, November 2011; Dan Dana's 1962 plans for the writing studio available at the Town of Los Altos Hills Planning Department. 11 See builder Dan Dana's 1962 plans for the writing studio available at the Town of Los Altos Hills Planning Department.; John Obed Curtis, Moving Historic Buildings (US Department of the Interior and International Association of Structural Movers, 1975, reprinted 1991). If it is necessary to store the building for a.period, JRP recommends that appropriate procedures for mothballing historic buildings be followed, such as Sharon C. Park, "Mothballing Historic Buildings," Preservation Brief No. 31 (Washington DC: National Park Service, 1993). 8 As discussed above, the proposed project would cause a substantial adverse change to two contributing elements of the historical resource: the main residence and former study/guest cottage. The proposed project would not cause a substantial adverse change to the writing studio, however, as it will be preserved such that it will still be able to convey significance under the CRHR. As discussed in Section 2, the writing studio was identified in the Assessment as the only individually eligible component of the property, as it is most directly associated with the writing career of Stegner. As such, while the demolition of the main residence and former study/guest cottage does constitute a substantial adverse change to the resource as a whole, as an individual resource the writing studio will still be able to convey its significant associations with Wallace Stegner. 3.2. MITIGATION MEASURE: DOCUMENTATION As part of compliance under CEQA Guidelines Section 15064.5(b)(4), the Town is required to identify feasible measures to mitigate the substantial adverse changes associated with the project, specifically the demolition of the main residence and former study/guest cottage. The following section identifies a feasible mitigation measure that could lessen the project's impacts to the historical resource. This proposed mitigation measure is intended to complement the preservation of the writing studio, which is already proposed by the project. If undertaken through fully enforceable permit conditions, the proposed mitigation measure, in conjunction with the project's preservation of the writing studio, could mitigate the proposed project to a level that is less than significant under CEQA. Documentation and recordation of the main residence, former study/guest cottage, and writing studio must precede any construction, demolition, or relocation activities. This mitigation measure must be undertaken by a qualified historian / architectural historian (under the Secretary of the Interior's Professional Qualification Standards). 12 This report recommends that the documentation follow NPS standards for HABS Historical Report Guidelines, as such standards will ensure the appropriate level of written and photographic recordation of the property's significant historic context and character -defining features. Use of HABS documentation guidelines is a standard method for preparing photographic and historic narrative documentation of historical resources for the purposes of project mitigation. The documentation of the former Stegner property should approximate HABS Level II documentation and include: a) select existing drawings, if available, that would be photographed; b) photographs following the NPS photo policy, of exterior and interior views, along with historic views, if available; and c) written data providing history and description of the property. Additionally, it is recommended that the 12 Secretary of the Interior's Professional Qualification Standards are defined in 36 CFR Part 61, available online at: b=://www.ni2s.!--ov/histom/local-law/arch stnds 9 htm. photographs include a view that illustrates the view from the writing studio to help illustrate the setting in which Stegner worked. 13 The Town would retain the documentation for public benefit and copies of the documentation would be offered to interested parties identified during project approval process, particularly all relevant historical organizations as well as organizations and collections dedicated to the work of Wallace Stegner. Table 1 includes a list of proposed recipients; however recipients need not be limited to those listed. There is no requirement that recipients must accept the documentation. The HABS documentation also could be made available via the Town's website. In addition, the HABS documentation would serve as a baseline of information for the preservation of the writing studio, which will be undertaken as part of the proposed project. The proposed documentation is intended for public dissemination and not intended to be reviewed by NPS or for transmittal to the Library of Congress and therefore, will not be a full -definition, HABS dataset.

The documentation would serve to provide an archival record of these physical characteristics, as well as a record of the property's relationship to the significant writing career of Wallace Stegner. Documentation of the property would provide a valuable addition to available archival material relating to the life and career of Wallace Stegner. As a prolific scholar and author with a career " NPS Heritage Documentation Programs website has the most recent editions of the Secretary of the Interior's Standards and Guidelines for Architectural and Engineering Documentation. See: bitp://www.nps.eov/histonLtdp/standards/index.htm. Also, Secretary of the Interior's Standards and Guidelines for Architectural and Engineering Documentation: HABS/HAER Standards, originally published in the Federal Register, Vol. 48, No. 190, (Thursday, September 29, 1983), 44730-44734; and Historic American Buildings Survey/Historic American Engineering Record Cultural Resources Program National Park Service U.S. Department of the Interior Washington, D.C. 20013-7127 1990. 10 M i that s armed 60 Y ears and included N works of both fiction and non-fiction, p Stegner left a rich archival record that has been well studied and curated by scholars across the country. Furthermore, a number of organizations continue to study and promote the Stegner's writings and scholarship, including the Wallace Stegner Center in Salt Lake City, and Wallace Stegner Environmental Center in San Francisco. Both organizations utilize the broad contexts and analysis of Stegner's work to continue developing research and scholarship pertaining to the American West and various environmental, social, and cultural themes. The Wallace Stegner Center develops research and degree programs through the University of Utah, public lectures, awards and fellowships, and publications, all of which are grounded in Stegner's research and scholarship. The Wallace Stegner Environmental Center in the San Francisco Public Library houses research material related to San Francisco Bay Area environmental concerns, offers public environmental programs, and holds a permanent collection of Stegner's personal copies of his books. Through their ongoing interpretation of Stegner's work, both programs serve to maintain and develop his legacy as a preeminent author and scholar. Additionally, Stanford University in Palo Alto, where Stegner was a professor, houses an extensive Stegner collection of papers, manuscripts, correspondence, and research notes in a comprehensively-curated 26.75 linear -foot collection. Notable materials include: • Correspondence, research materials, and typescripts relating to published works including Women on the Wall (1950), Sabrina (1962), Beyond the Hundredth Meridian (1954), A Shooting Star (1961), The Gathering of Zion (1964), Angle of Repose (1971). • Miscellaneous professional and personal correspondence, 1949-1992 • Wallace Stegner Interviews and Letters, including those with John Milton and Ansel Adams HABS documentation would serve as a beneficial accompaniment to this wide breadth of material and scholarship, as it would present a focused portrayal of the space in which Stegner produced much of his work. This focused effort would not be duplicative of existing Stegner archival resources, as no such documentation has been previously undertaken. Research for the HABS report could be partially based on the Assessment undertaken by the Town, however additional research and context development would likely be necessary to provide an adequate historical narrative. The research program should include material from the collections and repositories discussed above, which would provide the necessary contextual breadth and background relating to Stegner's life and work while residing at the subject property. 11 } 3.3. OTHER MITIGATION CONSIDERED, BUT NOT RECOMMENDED Other mitigation measures are employed in projects that impact historical resources, but are not recommended in response to this project. Mitigation measures used in other projects affecting historical resources include collection of oral histories, commemorative celebrations, development of archival collections, and creation of traveling exhibits, interpretive brochures, videos, websites, displays, and public art. The preceding examples of mitigation are not recommended because such measures would be largely duplicative of existing materials and activities regarding Stegner and his scholarly and literary legacy. Because Stegner's life and work is already catalogued in both his own literary works and several important collections, such compensatory, mitigation would fail to present new and beneficial information that is not already in existence. The mitigation measures proposed in preceding sections would serve this important purpose as they would address facets of Stegner's personal and professional surroundings that have not been well studied or curated to this point. 12 4. CONCLUSION The Town is reviewing an application for a Site Development Permit at 13456 South Fork Lane, Los Altos Hills, Santa Clara County, California. The proposed project includes a new residence, secondary dwelling, and swimming pool and would require demolition of the main residence and former study/ guest cottage of the late Wallace Stegner, an esteemed American author who owned and resided in the property from 1949 to the time of his death in 1993. In compliance with CEQA, the Town has determined that the property at 13456 South Fork Lane is a historical resource for the purposes of CEQA, as it is important for its association with the Stegner's productive life. This determination is supported by an Assessment undertaken by CIRCA on behalf of the Town in November 2011, which concludes that the subject property is eligible for the CRHR under Criterion 2 for its association with Wallace Stegner. 14 In this current report, JRP" concludes the proposed project would cause a substantial adverse change to the historical resource, as it would materially impair the main residence and former study/guest cottage. This report concludes that the proposed project would not cause a substantial adverse change to the writing studio, however, as it will be relocated to a compatible site on the property and preserved such that it will continue to convey its significant associations with Wallace Stegner. Pursuant to the requirements of the CEQA Guidelines, this Mitigation Analysis and Identification Report analyzes and identifies feasible measures to mitigate or avoid substantial adverse change to the former Stegner property historical resource. The report concludes that in conjunction with the preservation of the writing studio, HABS documentation of the property's contributing elements would serve as appropriate mitigation measure that would mitigate the proposed project's impacts to a level that was less than significant. While CEQA guidelines Section 15126.4(b)(2) states that documentation of a historical resource by way of historic narrative, photographs, or architectural drawings, as mitigation for the effects of demolition, generally will not mitigate impacts to a point where no significant effect on the environment would occur, this analysis finds that such documentation done in conjunction with the preservation of the property's most significant element—the writing studio— could mitigate the proposed project to a level that is less than significant under CEQA. The November 2011 Assessment of the subject property concluded that of the contributing elements of the historical resource, the writing studio was most significant because it was most directly associated with Stegner's writing career. This intimate association with the author's productive life surpasses the associations found in other areas of the property, as Stegner's significance lies in his development as one of the West's most prolific, heralded, and influential authors. Because of this embodied significance, the analysis provided herein concludes that the 14 CEQA Guidelines Section 15064.5(a)(3)(B) 13 A onsite relocation and preservation of the writing studio, in addition to the NABS documentation proposed as a mitigation measure, would be sufficient to mitigate the project's impacts to a level that is less than significant as the proposed project would allow for preservation and of the property's most significant component and archival recordation of all of its contributing elements. 14 5.

A new home is planned for this lot and your concern as to the future health and safety of the trees has prompted this visit. As required by the City of Los Altos hills, a survey of the significant trees and a tree protection plan will be included. Method: The significant trees on this site were located on a not to scale map provided by you. Each tree was given an identification number. This number was inscribed onto a metal foil tag and nailed to the trees at eye level. The trees were then measured for diameter at 54 inches above ground level (DBH or diameter at breast height). A condition rating of 1-100 was assigned to each tree representing form and vitality using the following scale: 1 - 29 Very Poor 30 - 49 Poor 50 - 69 Fair 70 - 89 Good 90 - 100 Excellent The height of each tree was estimated and the spread was paced off. In this report you will find a comment for each tree followed by a summary of my findings and a recommended Tree Protection Plan that should be in place for construction. 1 13456 S.

Summary® The trees on site are for the most part native oaks consisting of blue, valley and coast live oaks. The oaks on this site are in poor to good condition. The new proposed plan for the house and septic system has been located where impacts to the. trees will be reduced. Tree #11 a coast live oak with a diameter of 19.5 inches and a blue oak tree #10 will be removed to facilitate the planned home. Oak #11 is in poor condition with a distinctive lean over the existing home. The blue oak #10 is in fair condition but will not survive the planned construction. The root crown of 3 13456 S. Fork/10/12/10 oak #11 has been buried for some time most likely contributing to its poor condition. Two other oaks are in poor condition but due to their location the trees can be retained. The corner of the garage will encroach on the root zone of oak #2 rot loss is expected to be minor to moderate. Oak tree #9, #17 and #18 will be impacted by retaining walls. A 10 foot long and 20 inch deep exploratory trench was dug at the location of a planned wall at its closest point to tree #8. The roots located in the trench are as follows: • One 2 inch diameter root • One 1.5 inch diameter root • Several small roots less than .5 inches Root loss from the excavation for the wall will be minor to moderate and well within acceptable limits. Root loss to tree #9 and #17 should be less. The grade will be raised in the area near the northern comer of the proposed house. Retaining walls will be required near the oaks near this comer. It is critical that the excess soil not be piled on the root crown of these trees. Buried root crowns often are the cause of crown rot which leads to decline in oaks. A septic system will be required in the area below the existing driveway. The trenching for the leech lines will be hand dug when near protected trees. The depth of the trenching will help to distribute the excess liquid below the root zone of the water sensitive oaks. With proper tree protection impacts to the oaks will be well within acceptable limits. Tree Protection Plan: Tree Protection Zones Tree protection zones should be installed and maintained throughout the entire length of the project. Fencing for tree protection zones should be 6' tall, metal chain link material supported by metal 2" diameter poles, pounded into the ground to a depth of no less than 2'. The location for the protective fencing should be as close to the dripline of desired trees as possible, still allowing room for construction to safely continue. No equipment or materials shall be stored or cleaned inside the protection zones. Areas outside protection zones, but still beneath the tree's driplines, where foot traffic is expected to be heavy, should be mulched with 4-6" of chipper chips and covered with 3/4 inch plywood. The spreading of chips will help to reduce compaction and improve soil structure. The tree protection zones for the neighbor's trees must be maintained throughout the entire project. Demolition and site access All tree protection must be in place prior to the start of the demolition process. Demolition equipment should access the property from existing driveways if at all possible. The existing driveway and garage slab shall remain until all construction is completed. If equipment is to stray off of existing driveways 4 to 6 inches of chipper chips should be spread under driplines of existing trees. This type of landscape buffer will help to reduce compaction of root zones. Truck loading should be carried out on the existing driveway. 2 13456 S. Fork/10/12/10 Root Cutting and Grading Any roots to be cut shall be monitored and documented. Large roots (over 2" diameter) or large masses of roots to be cut must be inspected by the site arborist. The site arborist, at this time, may recommend irrigation or fertilization of the root zone. All roots needing to be cut should be cut clean with a saw or lopper. Roots to be left exposed for a period of time should be covered with layers of burlap and kept moist. The over dig for the foundation should be reduced as much as possible when roots are encountered. Trenching and Excavation Trenching for irrigation, drainage, electrical or any other reason shall be done by hand when inside the dripline of a protected tree. Hand digging and the careful placement of pipes below or besides protected roots will significantly reduce root loss, thus reducing trauma to the tree. All trenches shall be backfilled with native materials and compacted to near its original level, as soon as possible. Trenches to be left open for a period of time, will require the covering of all exposed roots with burlap and be kept moist. The trenches will also need to be covered with plywood to help protect the exposed roots. The installing of the septic system will require a great deal of trenching. The site arborist .shall inspect any trenches within the driplines of protected trees. Irrigation Normal irrigation shall be maintained on this site at all times. The oaks under normal conditions should not require irrigation during the summer months unless their root zones are traumatized. For traumatized oaks on a construction site, I recommend irrigation during winter months, 1 time per month. Seasonal rainfall may reduce the need for additional irrigation. During the warm season, April - November, my recommendation is to use heavy irrigation, 2 times per month. This type of irrigation should be started prior to any excavation. The imported trees will require normal irrigation. The irrigation will improve the vigor and water content of the trees. The on- site arborist may make adjustments to the irrigation recommendations as needed. The foliage of the trees may need cleaning if dust levels are extreme. Removing dust from the foliage will help to reduce mite and insect infestation. The information included in this report is believed to be true and based on sound arboricultural principles and practices. Sincerely, Kevin R.

I have reviewed Mr. Yong's plans for redevelopment of his property and am pleased that his proposed residence recalls the style of the original Stegner home. I have also followed the ample recent press coverage of his project and have thoroughly reviewed the May 27 National Trust Letter opposing the demolition of the original Stegner residence and study, citing that CEQA Guidelines require a full environmental review due to the historic nature of the property. My understanding is that Mr Yong did extensive due diligence when purchasing the property and was assured by the Stegners that no historic designation existed for any structure or portion of the property. Therefore I am quite surprised by the National Trust's letter, delivered three days before his permit hearing, in the midst of a holiday weekend. Surely any concerns about preserving historic aspects of the property should have been discovered and addressed earlier in the planning process. Let us assume for a moment that an environmental review will be required and performed, and that it will be concluded that portions of the building(s) must be preserved. For what purpose? The property is accessible only by a long private road traversing four adjacent properties, and then by a long steep narrow driveway suitable for cautious one-way traffic. The buildings are invisible from off site and can only be viewed by determined trespassers. Who would benefit from the preservation of these unlisted structures? Wallace Stegner's legacy is amply preserved in his writing, the various University Centers dedicated to his teachings, the permanent History Room bearing his name at the San Francisco Public Library and by countless other programs related to his work. The Town's History Committee has proposed a possible mitigation by relocating the Study to a publicly accessible site and is currently investigating where that site might be. I understand that Mr. Yong agrees to cooperate in the relocation effort. I respectfully urge the town to diligently pursue the `Study Relocation' option as sufficient mitigation to satisfy the CEQA requirement and permit Mr. Yong to obtain his `fast track' permits without additional delay. I worry that by delaying the start of construction until another building season is lost, Mr. Yong's development expenses will increase significantly and the quality of the project could suffer. Because I am the adjacent neighbor and because we share a common driveway, I would be most immediately affected by changes to the project. But the town would suffer as well by compromising the quality of the finished job. Mr. Yong has worked hard to meet all planning and town committee requirements. In addition, he has requested no variances and has worked successfully with his architect to fit the new building to the site with minimal disruption of the existing terrain. Please help him to see the project to fruition as expediently as possible. Thank you for your kind consideration.

I support the views and arguments put forward in the letter by Michael Kuranoff. Relocation of the study is an excellent compromise, even though I think Wally Stegner, with whom we were good friends for the last few years of his life, would shake his head about such an effort; he would want to be remembered by his writings, and his students and his student's students for his teaching and his wisdom. Therefore, I urge the town to approve the development permit in its current form.

However, if the Yongs were not informed of the historical background of this property when it was sold to them by his daughter, they should be allowed to go forward with their development. The latest article in the Town Crier by Elliott Burr citing Brian Turner, atty. for the National Trust for Historic Preservation got my attention. He was quoted as saying "Although the homeowners purchased the house on the open market, anyone in California should buy a property knowing 'full well there are regulations in the state for the protection of historical resources'." WHATM You mean every perspective home buyer has to research to find out if there is a "possible historic significance"? If this isn't a case of property rights vs. unknown regulation I don't know what is. A solution would be to move it to another location in large sections to reassemble it elsewhere—in a timely manner. The Yongs should be compensated for any losses therein. Perhaps Brian Turner can convince the National Trust for Historic Preservation to fund this project. Sharen Schoendorf 2 of 2 6/15/11 10:32 PM Brian Froelich Subject: FW: Stegner study -----Original Message ----- From: Heinz Furthmayr Finailto:hfurtastanford.edu] Sent: Thursday, March 22, 2012 11:08 AM To: To; Gary Waldeck; John Radford; Jean Mordo; Ginger Summit Subject: Stegner study As one of the neighbors I have been following the fate of the Stegner Property before and after its sale. Living in our house on South Fork Lane for over 20 years, we considered ourselves fairly close friends of Mary and Wally and spent time together in each of our houses on numerous occasions, as well as visited Town Hall together during various meetings on behalf of issues concerning our neighborhood. I believe that I 'know' at least of some of Wally's feelings and opinions. Thus, I have been following an initiative of a small group of 'activists' in our town for some time with amazement, namely to 'rescue' and to 'immortalize' Wally Stegner's study before its demolition. There are various issues that I feel would be in need to be addressed, and I have abstained from responding until now. However, there is one that I would like to formulate with this message: Wally, and for that matter Mary, would never have approved of lending his name to a trail along Matadero Creek, nor would he have approved of turning his study into a memorial. Thus, I consider this effort as totally misguided. It would be far more in Wally's spirit to consider alternative means of keeping his ideas and memories alive. One example of this already exists in the form of the Wallace Stegner Environmental Center in San Francisco. Therefore, I strongly feel that our town should not support the effort to save a building and to place it on the Town Hall Property or any other public land. As private citizens, this group can obviously pursue this and has pursued it in peculiar ways. It has not considered, however, to remove it ASAP at their cost, as to protect the current owner, and to also identify and provide private lands for placement of this not so attractive building. In our neighborhood, I am not alone with this view and I will quote one of them in answer to the latest e-mail that also has been communicated to you: "...... Doesn't this mean that the History committee has "recommended" that the town put the study on town land but says nothing of the town's accepting the recommendation. Or, what monies would be spent to renovate and run it. It would be a lovely come back if all the immediate neighbors would protest the move on the grounds that the town has no right to accept the financial obligation of running the thing. I would also object to the tree trimming and gate moving needed to get it down private driveways, andout onto public roads. Who is to assume responsibility for driveway damage, is Les?" Best regards, Heinz Furthmayr TOO LITTLE, TOO LATE As much as Wallace Stegner's work was loved by many it seems that this request to save his studio should have been made years ago by Stanford since they knew the property would have to be redeveloped considering its condition when it was acquired 4 years ago. If Stanford thought nothing about its historic preservation why would anyone else instigate this delay? There are artifacts and perhaps burial grounds of previous settlers scattered through the hills and if this project is delayed who will be next on specious claims of historic importance. Those who attempt to impose restrictive property rights not included in our Town building codes should be forced to shoulder the full cost of any delay. The sun has set on Wallace's legacy and a mere studio is not fitting as a reminder of his important contributions. Wallace's presence was the inspiration for the many students that visited him and not the studio. I am sure Stanford would want to propose the best solution that does not unfairly cost Yew -Nam anything. Wallace's work better embodies his spirit and thoughts and the studio is only one place he enjoyed working. If anyone wants the studio they should move it immediately at their own expense. My suggestion is to video not only the studio but also the surroundings that so inspired Wallace to create his vast collection of works and have them available at Stanford or perhaps Town Hall. Stanford turned the property down as they would have preferred the money the property would have fetched. Has anyone given any thought if this property is given historic landmark status? Who will bear the expense of maintaining the place and greeting everyone who wants to visit? The studio is far removed from any road so preserving a structure for no one to see seems pointless. In the last four years has anyone visited this property to be inspired by Wallace's work? Los Altos Hills has many residences that were owned by historic figures from Silicon Valley and although their estates are many years from the wrecking ball, if this passes who is next on the do not rebuild list. What seems fair is for those that want to preserve a relic of the past is to justly compensate Yew -Nam for his loss in not being able to build either now or at all. It should not be Yew -Nam and his family. With all of the restrictions on his project there is no other place to build. I trust the town will give speedy consideration to moving his project along as there seems to be no legal reason not to. I am Yew-Nam's next door neighbor.

However it then proposes to "preserve" it by dropping it in a black hole and claims that conforms with state regulations covering such preservation. In my view that is an invalid conclusion, as discussed below. The cited document contains some historical and other errors but happily recognizes the historical significance of Stegner's Study and advocates preserving it. However it proposes that both the house and the dilapidated old cottage be demolished and that the Study be moved to the inaccessible location of the cottage, which is on a steep slope in the dark part of the forest, a rather different environment from its current location on a sunny hilltop. The owner apparently wants to continue using it as a cottage, which is the way it has been used in recent years. That certainly does not look to me like an attempt at preservation and seems to go against some of the historical preservation regulations that the report claims to uphold. I have been attempting to reach the owner to discuss alternatives such as our proposal to move the study to another site where it would be turned into a Stegner museum, which the owner agreed to earlier. However I have been unable to reach him so far. The accompanying Notice of Intent IQ says that comments on this proposal must be submitted to the Town by April 30 at 5:00pm in the manner described there. Public hearings on this matter are scheduled before the Planning Commission on May 3 at 7:00pm and before the Council on June 21 at 7:00pm. I suggest that interested people mark those dates and times on your calendar. Errors and inconsistencies There is an odd inconsistency in terminology used in the CEQA review j11. As we learned from members of the Stegner family long ago, Wallace Stegner called the place where he did his writing a "study." The report uses that term for the first place he used --actually they call it "study/guest cottage," given that it was later expanded into living quarters. However they call his newer study a "writing studio" for no apparent reason. The notes below will use the terms "cottage" and "study," in order to be consistent with Stegner's terminology. The remarks below are keyed to the page and paragraph numbers of j1l. P. 10.9 "The applicant is proposing to preserve the writing studio and relocate it to the site of the former study/guest cottage west of the main residence on the property." The site of the cottage is downhill from the residence. That is a dark place on a steep slope in the middle of a dense forest with very limited sight lines and is a radically different place from where the study is L.tfiv.•//csnxnx� etanfnrri arin/,,,laarnr et/etarrnar/ramia litm 11/1)S/17A11) Review of a CQUA review of Stenger's Study Page 2 of 5 currently located --a sunny spot at the top of a hill overlooking an oak forest --and is relatively inaccessible. However that arguably wouldn't matter much because it would not be open to the public. In order to move the study into the forest location it likely would have to be dismantled and reconstructed on the new site. Alternatively it might be possible to cut some of the overhanging tree limbs and lift the building intact using a high performance helicopter and drop it into the proposed site. In either case it likely would be necessary to abandon the existing bathroom at one end, so in order to use it as a cottage the owners would likely want to build a new bathroom on the new site. All of this would cost the owners much more than our offer to move the study away at no cost to them to become a museum but that would mean that if they want a separate cottage they would have to build one. p. 26.4 "This report has reviewed all potential impacts and the new residence project and the relocation of the writing studio do not have any foreseeable or unmitigated impacts as defined in this initial study." I believe that moving the study to a dark place on a steep slope in the middle of the forest with no view actually would have a very foreseeable impact. That arguably would be not much different from demolishing it. p. 35.6 "Ohlone Indians were the first known residents of Los Altos Hills." That statement, which is taken from the "Town History" web page, is incorrect in that they were the last native group here before the European invasion, not the first. The Town History web page is evidently based on Florence Fava's fake history [3], which is full of errors. I've been trying to get it fixed since 2008 and will keep trying. The ancestors of the Ohlone probably arrived here around 8,000 years ago, when there was no San Francisco Bay because of lower sea levels coming out of the last Ice Age. However, the earliest people arrived here at least 16,000 years ago and probably much earlier. Unfortunately they all died in an environmental disaster about 12,900 years ago that, likely was caused by a comet or meteor impact on the North American ice sheet in the vicinity of the Great Lakes. It killed all plant life in North America for a time with the result that large land animals all starved to death, including mammoths, giant bison, giant tree sloths, camels, several kinds of horses and many others. As a further result, the human hunters also starved to death as did other predators such as the large saber tooth cats that lived here. This region was eventually repopulated with both humans and smaller animals coming from Asia and Central America. p. 36.2 "Following roughly the path of today's Fremont Road, Juan Bautista De Anza passed through what was to become Los Altos Hills while making his journey from Monterey to San Francisco in 1776 to establish the Presidio." This is another false claim from the Town History web page that was fabricated by Florence Fava, the former Town Historian, in order to justify participating in the U.S. Bicentennial Celebrations of 1976. It was used at the time as a basis for getting the Town to put up two stone monuments on Fremont Road with bronze plaques making the same erroneous claim. There was also a fake reenactment of this non- event using costumed horsemen. In 2010 I convinced the Town History Committee and the Council that the fake monuments should be removed j41 and, with support from the National Park Service, that happened a short time later. p. 36.6 "Both Morgan Manor and Griffin House are official Town Historical Landmarks." L++«. //.....,.., ,.+..« «,] ,.,7../ 1,.,.—«,...+/..+,.,.«,...L--- ..,. L+_ a 1^1 /^n n Review of a CQUA review of Stenger's Study Page 3 of 5 That is incorrect. Title 11 of the Municipal Code f51 specifies procedures for designating historical landmarks, but despite elaborate preservation goals stated in the Conservation section of the Town's General Plan L61, those procedures have been consistently ignored, with the result thatno such landmarks have been designated. There is an Inventory of Historical Sites and Structures M in Appendix 4a to the General Plan that is substantially incomplete but it has no administrative function, so as pointed out in the "Wild Goose Chase" section of my earlier report fes, it should be removed from the General Plan. p. 42.3 "The former Stegner property was developed in the late 1940s (before the incorporation of the Town) however, no documentation revealed that it was directly associated to the early planning and/or development of the Town of Los Altos Hills." This overlooks the fact that Stegner was'a principal instigator of the controversial incorporation of the Town of Los Altos Hills and set many of its anti -development goals enunciated in the primary document used to sell the proposed incorporation, namely the "Green Sheets" F91. Wallace Stegner as a listed participant in that project and anyone familiar with his writings can see that the key arguments were written by him. p. 46.3 "The Town of Los Altos Hills has not officially reviewed or adopted the property at 13456 South Fork Lane as a historic resource." As noted above for p. 36.3, the Town has not adopted any property as a historic resource. However on May 17, 2011, which was before the Town's History Committee had figured out that the List of Historic Sites and Structures in the General Plan actually has no function, they voted unanimously to place both the Stegner residence and the one that formerly belonged to Hewlett-Packard founders and philanthropists David and Lucile Packard on that list. As usual, the Town Council ignored those recommendations without explanation. Note that Footnote 34 claims that "Some member of the Los Altos Hills History Committee did meet in May 2011 to discuss the possibility of adding the Stegner property to the Town's Inventory of Historic Sites, however no official action was taken at that time." That is a blatant lie inasmuch as the resolution cited just above was adopted unanimously by the History Committee and was reported in the official minutes of their May 17, 2011 meeting. I would be interested to know who provided this misinformation to the author, Sheila McElroy. p. 46.4 "Individually, the only structure that meets the NR [National Register] criteria would be Stegner's writing studio [i.e. his study]." Happily this means that, despite a bit of confusion about the history, the right conclusion has been reached about the historical significance of the study. p. 55.5 "Under this CRHR [California Register of Historical Resources] Special Consideration a historical resource must retain its historic features and compatibility in orientation, setting and general environment. Under the proposed project, these Special Conditions are met, as the project will preserve the character -defining features of the building and the general rural residential location and setting that is associated with Wallace Stegner's use of the building." That argument looks bogus to me. How does dropping the study into the middle of a dark forest "preserve the character -defining features of the building"? p. 57.2 "Furthermore, there is no indication that any of Stegner's original belonging [sic] that http://www.stanford.edu/—leamest/stegner/cequa.htm 4/25/2012 V Review of a CQUA review of Stenger's Study Page 4 of 5 were in the writing studio are extant at the property and the Assessment states that interior wood paneling and shelves have been removed." There would not be much point in placing Stegner's furnishings in that building if it is being converted into a cottage, where the primary furnishings would be beds and dressers. However if we are able to preserve it as a study it will be our plan to restore its interior as much as possible. In response to an earlier inquiry from me, Lynn Stegner (Wallace's daughter-in-law) wrote: "yes, we did preserve the artifacts, typewriters, desk, books (of course) shelves, etc. Some are at the University of Utah, but the desk is in Santa Fe and the rest Page and I have." With the Stegners' cooperation we would hope to get some of those furnishings for the museum and to match the rest as closely as possible. p. 57.3 "it appears that the writing studio could be moved to the new onsite location without causing damage to or destruction of the building." Note that this doesn't say how the move might be done. Moving a building into the middle of a forest without damaging it and without cutting down a lot of trees is a nontrivial task. p. 58.1 "The proposed project would not cause a substantial adverse change to the writing studio, however, as it will be preserved such that it will still be able to convey significance under CRHR." But how does converting the study into another cottage convey this significance? If it is supposed to serve some other function in its new location, what is it? Conclusions In summary, the report f 11 appears to be a bogus attempt to circumvent existing regulations on historical preservation. If you have the time, I invite you to look it over and identify additional holes in their logic, document them according to 21 and, if possible, show up at the public hearings specified in 21 and at the beginning of this note.

Partial response suggested by JRP Historical Consulting, LLC The California Code of Regulations, Title 14 Section 4852(d)(1) recognizes that if a historical resource (i.e. building or structure that is listed in or eligible for listing in the California Register of Historical Resources, or CRHR) is moved to prevent its demolition at its former location and if its new location is compatible with the original character and use of the historical resource, the resource will remain eligible for listing in the CRHR. Under this CRHR Special Consideration, a historical resource must retain its historic features and compatibility in orientation, setting, and general environment, recognizing that with adequate planning and protections a moved historical resource can retain sufficient integrity to convey its historic significance. Therefore, following the standards set forth in the CRHR, the act of moving a historical resource can be concluded as not causing a substantial adverse change under CEQA Guidelines Section 15064.5(b). The CRHR Special Consideration for moved buildings will be met by this project, as it will preserve the character -defining features of the writing studio and its rural residential location and setting that is associated with Wallace Stegner's use of the building. Moving the writing studio (also referred to as Stegner's study) to the concrete slab foundation of the former study/guest cottage will preserve the building's physical orientation and proximity to the adjacent landscape and provide the historical resource a sufficiently similar setting and general environment to what it currently has. The trees around the former study / guest cottage and the writing studio are mature and are likely larger than 1 they were when Stegner occupied the property. The writing studio's new location is at a modestly lower elevation, which will somewhat change views from the building, but this site preserves important aspects of the building's hillside, rural, and remote orientation and setting, and it will continue to provide some views of the adjacent landscape. Furthermore, CEQA does not have requirements that historical resources moved to prevent demolition must be publically accessible, CEQA Guidelines Section 15064.5(b)(3)-(4) do not prescribe specific methods by which a historical resource may be moved, and under CEQA Guidelines Section 15126.4 (a)(1) the cost of moving a historical resource is not a specific consideration relative to a project's compliance under CEQA. Rather, CEQA Guidelines 15064.5(b)(3)-(4) specify that projects impacting historical resources should be conducted in a manner that meets the Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings and that identified mitigation measures need to be feasible. The project is intended to be conducted following the Secretary of Interior's Standards using the Preservation Treatment. Furthermore, the project will follow applicable National Park Service guidance for moving historic buildings. As a modestly -sized wood frame building of relatively modern construction, it appears likely that it will be feasible to move the building. This may require some disassembly of the building, as identified by the project engineer and a qualified building mover. The project will likely not move the building's bathroom and does not intend to construct a new bathroom after the building is moved. p. 55.5 "Under this CRHR [California Register of Historical Resources] Special Consideration a historical resource must retain its historic features and compatibility in orientation, setting and general environment. Under the proposed project, these Special Conditions are met, as the project will preserve the character -defining features of the building and the general rural residential location and setting that is associated with Wallace Stegner's use of the building." That argument looks bogus to me. How does dropping the study into the middle of a dark forest "preserve the character - defining features of the building"? Partial response suggested by JRP Historical Consulting, LLC CEQA standards for a moved historical resources new site require compatibility in orientation, setting, and general environment.

But how does converting the study into another cottage convey this significance? If it is supposed to serve some other function in its new location, what is it? Partial response suggested byJRP Historical Consulting, LLC The Town has concluded that the former Stegner writing studio is a historical resource for the purposes of CEQA, i.e. that the building is eligible for listing in the CRHR. This is based on the evaluation conducted by CIRCA in November 2011, which concluded that the writing studio retained sufficient historic integrity to convey its significance. At the time of the evaluation, the writing studio was not being used as a study or a use similar to Stegner's. Its current use as a cottage or storage was considered to be sufficient compatible such that the building retained physical characteristics such that one could comprehend the writing studio's importance for its association with Stegner. The use of the writing studio following mitigation will continue to be similar to the use it had when the building was evaluated for its historic significance. This project does not change the use of the historical resource in a manner that diminishes its integrity. 3 Attachment 11 Joan Reinhardt Reiss, Ns - - — -- 773 Duncan Street — San Francisco, CA 94131 415 647-2687 — h einhardtreiss@tmaiCcom — jrreisswriter.com To: Los Altos Hills Town Council acliry D Los Altos Hills Planning Commission c/o: Brian Froelich, AICP, Associate Planner APR 2 5 2012 bfroelich@losaltoshills.ca.gov TON OF iosAUos HUs Fr: Joan Reinhardt Reiss, M.S. OqOVZR Regional Director, The Wilderness Society (1990-93) Re: Wallace Stegner Writing Studio now at 13456 South Fork Lane During my tenure as Wilderness Society (TWS) Director, Wallace Stegner served on the Governing Council. Having read most of his published works, I was so honored to make his acquaintance. His numerous awards included both a Pulitzer Prize and two National Book Awards. In 1964, he founded the Creative Writing Program at Stanford, and influenced a generation of writers including LarryMcMurty, Raymond Carver, and Scott Turow to name a few. Environmental activism was always part of his soul. In 1990, TWS was monitoring the Park Service Plan for Yosemite. Wallace Stegner came to the hearing and provided eloquent and moving testimony. Now is the time to honor Wallace Stegner and his enormous contributions to literature and environmental activism by placing his writing studio in an easily accessible public location adjacent to the Los Altos Hills Town Hall. As you probably know, this recommendation originated from a unanimous vote by the Los Alto Hills History Committee in March 2012. What a shock to read the April 2012 site development permit learn that the writing studio will be moved but remain on the private property of the new owners at the the South Fork Lane site.

Now is the time to honor Wallace Stegner and his enormous contributions to literature and environmental activism by placing his writing studio in an easily accessible public location adjacent to the Los Altos Hills Town Hall. This recommendation originated from a unanimous vote by the Los Alto Hills History Committee in March 2012. What a shock to learn the April 2012 site development permit would allow the writing studio to be moved but remain on the private property of the new owners at the South Fork Lane site. This is a clear denial of public access to an important literary memorial. Request to the Planning Commission and Town Council Follow the unanimous recommendation of your History Committee, vote to move the Wallace Stegner Writing Studio/Study to a site near Town Hall for easy public access. r-) PATHWAY COMMITTEE NIINUTES 2004 -2011 Los Altos Hills Pathway Committee FINAL; Minutes of Meeting November 22, 2010 1. ADMINISTRATIVE Eileen Gibbons called the meeting to order at 7:05 PM Members present: Ann Duwe, Courtenay Corrigan, Nick Dunckel, Bob Stutz, Sue Welch, and Denise Williams Members absent: Tim Warner LAH Council Members present: Ginger Summit Members of the public present: Dan Rasmussen, 27589 Samuel Way Thomas Rasmussen, 27589 Samuel Way Robert Rasmussen, 27589 Samuel Way Gerry Parco, representing 27641 Purissima Road Pam Allison, representing 27641 Purissima Road Bob Lehto, representing 27641 Purissima Road Heinz Furthmeyer,13500 South Fork Lane Wan -Lei Yong, 13456 South Fork Lane Quyue Qulia) Chu, 13408 South Fork Lane Tsungwei Chin, 25354 La Rena Lane The agenda was approved as published. 2. COMMUNICATIONS FROM THE FLOOR None 3. NEW BUSINESS A. Property Reviews. The following properties were reviewed for pathway recommendations: 13456 South Fork Lane (Lands of Yew -Nam and Wan Lei) The reason for pathway review is construction of a new residence. The homeowner, Wan -Lei Yong, was present. The property is the east end of South Fork Lane, a cul-de-sac that is private adjacent to this property. Information from the Town indicates that the part of South Fork between here and Middle Fork Lane is a public road, although a South Fork resident says this part is also private road. The Town holds an over -the -road easement on part of South Fork but this route was removed from the Master Path Plan in 2005. The Town holds a 10 -foot off-road pathway easement along the full length of the east side of 13456 South Fork The off-road Master Path Plan approved by the City Council in 2005 shows this path, which will connect to off-road paths (also approved on the Master Path Plan) through the Sterling property (28030 Natoma) to be established when that property is subdivided. The easement also connects to an existing off- road pathway that runs from the end of South Fork Lane to Middle Fork Lane and to Byrd Lane. These off-road paths form part of the connections between Natoma Road, Page Mill Road, and the Wallace Stegner scenic pathway. Ms Wan Lei expressed concerns about any path using South Fork Lane because it is steep and narrow. She also noted that walkers sometimes get lost in the area and wander up their driveway looking for the path It was suggested that the Town or the owners improve the pathway signage to avoid this. PWC discussed the value of this connection to the Sterling property. Courtenay Corrigan moved that the Town ask the owners of Pathway Committee Minutes 2004 - 2011e.doc Compiled 3/11/2012 Page 297 Attachment 12 0 PATHWAY COIV lv=E MINUTES 2004 -2011 13456 South Fork lane to maintain the existing 10400t off-road pathway easement on the east side of the property and that the Town not allow any fencing, landscaping, or other obstructions to be placed within this easement. The vote was unanimously in favor. 2. 25354 La Rena Lane (lands of Chin). The reason for pathway review is construction of a new residence. The homeowner, Tsungwei Chir, was present. The property is on the north side of La Rena, a public cul-de-sac that serves more than eight residences. A IIB path in good condition exists on La Rena on the side opposite this property and continues along La Rena on that side in both directions. La Rena is not on the official list of streets designated to have pathways on both sides. Sue Welch moved that the town collect a pathway in lieu fee from the owner of 25354 La Rena Lane. The vote was unanimously in favor. 3. 27641 Purissima Road (review of bridge requirements in Morrison subdivision). This 12 - acre property was reviewed by the PWC in Feb 2006 at the time of subdivision and again in Feb 2007 after a change in the subdivision layout and an increase in the number of lots to six. The PWC considers the connection from Purissma Road to La Cresta Drive important and the off-road Master Path Plan approved by the City Council in 2005 shows an arrow through this subdivision, indicating an off-road pathway connection The recommendation at that time was to request an easement in the road on the new cul-de-sac that is being built part way through the subdivision From the end of the cul-de-sac, the path will follow a driveway, then a 10 -foot wide off-road pathway easement across to the eastern edge of the property to eventually connect to La Cresta. In addition, a north -south easement connecting to the existing easement on the NE border of 12489 Canario Way was required. The developers are now requesting a change in the route of the path because the concrete bridge carrying the new road over Deer Creek apparently is not wide enough for a separate pathway. A PowerPoint presentation and handouts describing the proposed new route were shown. The proposed new route would meander through the conservation easement on the west side of Deer Creek, cross the creek on an existing smaller bridge that is on the neighboring property (27589 Samuel Way, lands of Rasmussen), and then meander back to the road. The pathway easement from Purissima Road directly to this small bridge has been removed from the MPP. The Rasmussen were present and expressed their concerns about loss of privacy because the small bridge is very close to their home and visible from points on their property. The committee and others present discussed the route option at length. The consensus of the PWC was that the proposed new route would be very intrusive to the Rasmussen property and as currently shown would run too close to the top -of -bank on the east side of the creek Apparently three other small bridges cross Deer Creek further north on the subdivision property that might be used. It was also recommended that the Town consider allowing pedestrian to walk in the right-of-way of the road bridge. Use of the existing road bridge is consistent with pathway rules for cul-de-sacs serving eight or fewer lots, where pathways are not required to be separate from the roadway. The consensus of the PWC is that the road bridge is neither too narrow nor too steep for pedestrians Nick Dunckel moved that the Pathway Committee finds that use of the existing pedestrian bridge on the Rasmussen property (27589 Samuel Way) for the pathway is far too intrusive to the Rasmussen property and that the developers of 27641 Purissima Road provides some other route across the creek for the pathway. The subdivision developers have 12 acres to provide an appropriate route across the creek It was also recommended that the Town review use of the existing road bridge and consider Pathway Committee Minutes 2004 - 2011e.doc Compiled 3/11/2012 Page 298 i' Attachment 13 Brian Froelich -------_--------_._., From: Roger Spreen [roger@krillion.com] Sent: Thursday, April 21, 2011 11:46 AM To: Brian Froelich Cc: Debbie Pedro Subject: OSC Meeting recommendation on 13456 S. Fork Lane Brian The Open Space Committee met this morning. I introduced the Yong project, and in.response, the committee voted 6-0 for the recommendation below, with 2 abstentions: Sharon Shoendorf because she's a direct neighbor of the property, and me, since I was introducing & explaining the property, and wanted to remove myself from influencing any committee action. Let me point out that Council Member Mordo was in attendance, and one of our committee members, Sue Welch, was also quite familiar with the property and the project because she also sits on the Pathway Committee. Thus, I feel there was objective, independent analysis & thought about this project.. 4/21/2011 Open Space Committee meeting Recommendation with regards to the proposed project at 13456 S. Fork Lane: The OSC does not find any specific conditions on this property that warrant allowing exceptions to the.Town's standard policies on open space easements. For this reason, the OSC does not support allowing lights, gates or other accoutrements in the open space easement on this parcel. Furthermore, the OSC supports adhering to the complete 30% sloped area to define the open space easement boundaries, as is standard practice. The OSC also recommends including a 10 -foot connecting corridor to the adjacent property (lands of Stirling) in the "less than 30% slope" area to assure future connectivity. A vote was taken. The Chair, Roger Spreen, abstained, as did the owner of a neighboring property, Sharon Schoendorf. Votes in favor of the recommendation: George Clifford, Nancy Couperus, Alice Sakamoto, lean Struthers, Wendie Ward, Sue Welch. One member absent: Karen Lemes.

Geologic, .and ..Geotechnical..,: Investigation- (report)-_-.-.. :prepared by. Murray Engineers, Inc.; dated --September 30,.2010; • Architectural Plans (11 sheets), prepared by Raymond L Neal, dated November 9, 2010; Topographic, Grading and Erosion Plans (5 sheets), prepared by Giuliani and Kull, Inc., dated November 5,2010; and Septic System Plans (2 sheets), prepared by S.R. Hartshell, dated October 11, 2010. In addition, we have reviewed pertinent maps from our office files and completed a recent site inspection.

Our packet of project plans did not include expected cut and fill volumes, but we anticipate a significant excavation for the proposed basement. The proposed residence is located immediately south of the Monta Vista fault as depicted on the Town Geologic Map. SITE CONDITIONS The project site is generally characterized by gentle to very steep (approximately 5 to 70 percent inclination) north to northwest facing slopes. Previous grading on the site has resulted in an existing cut and fill pad beneath the existing house. The southwest portion of the building pad is a moderately steep (approximately 25 percent inclination) fill slope. Other gentle to moderately steep ( approximately 5 to 25 percent inclination) fill prisms were noted on the outboard edge of the existing driveway, landscaping areas and trails surrounding the northern portion of the existing residence. In addition, previous grading for the existing guest house has resulted in a cut and fill pad. Natural drainage at the site is characterized by sheetflow to the northwest and north. Signs of expansive soil were noted along slopes adjacent to the residence. Cracked asphalt, tilting retaining walls and uneven walkways were noted at the property. The Town Geologic Map indicates that the site is underlain, at depth, by bedrock of the Santa Clara Formation (semi -consolidated to consolidated, comprised of yellow- brown to red -brown conglomerate interbedded with poorly sorted sandstone, siltstone and claystone), and greenstone, limestone and sandstone bedrock materials of Franciscan Complex. The existing residence is located immediately south of the mapped Monta Vista fault, and 2.76 miles northeast of the San Andreas fault. Based on the findings of the referenced report by Murray Engineers, the proposed residence is located from 25 to 30 feet south of the identified Monta Vista fault. The fault plane has been depicted as descending beneath the proposed basement floor at depths on the order of 20 to 40 feet. CONCLUSIONS AND RECOMMENDED ACTION The proposed residential development is constrained by expansive surficial soil material, potential creep and settlement of existing site fill materials, the close proximity of the Monta Vista fault, and anticipated strong to violent seismic ground shaking. The Project Geotechnical consultant has investigated the property in a manner consistent with prevailing geologic and geotechnical standards and has concluded that the site is suitable for proposed improvements. To mitigate the potential for ground deformations or secondary ground cracking associated with the nearby fault, the Geotechnical Consultant has recommended that the basement be founded on a reinforced mat slab COTTON, SHIRES AND ASSOCIATES, INC. r Brian Froelich Page 3 November 22, 2010 L5220 that is to be a minimum of 10 inches in thickness. We note that the local trace of the Monta Vista fault is highly sinuous, has a low fault plane dip angle, and has an uncertain potential for transmitting possible future primary fault rupture displacements. These factors reduce the level of geologic concern about the proximity of the identified fault to the proposed project. We do not have geotechnical objections to the layout of proposed site improvements or the presented project geotechnical design criteria. We recommend that the following conditions be attached to geotechnical approval of the subject application: 1. Geotechnical Plan Review - The applicant's geotechnical consultant should review and approve all geotechnical aspects of the project building and grading plans (i.e., site preparation and grading, site drainage improvements and design parameters for foundations and retaining walls) to ensure that their recommendations have been properly incorporated. • The Project Geotechnical Consultant should review the proposedenergy dissipater placement in the northeastern portion of the property and recommend any appropriate revisions from a geotechnical perspective. The results of the Geotechnical Plan Review should be summarized by the geotechnical consultant in a letter and submitted to the Town Engineer along with other documents for building permit plan -check. 2. Geotechnical Construction Inspections - The geotechnical consultant should inspect, test (as needed), and approve all geotechnical aspects of the project construction. These inspections should include, but not necessarily be limited to: site preparation and grading, site surface and subsurface drainage improvements, and excavations for foundations, and retaining walls prior to the placement of steel and concrete. At the end of projection construction, the consultant should inspect completed site drainage improvements to confirm compliance with geotechnical standards. COTTON, SHIRES AND ASSOCIATES, INC. a Brian Froelich November 22, 2010 Page 4 L5220 The results of these inspections and the as -built conditions of the project should be described by the geotechnical consultant in a letter and submitted to the Town Engineer for review prior to final (as -built) project approval. LIMITATIONS This geologic and geotechnical peer review has been performed to provide technical advice to assist the Town with its discretionary permit decisions. Our services have been limited to review of the documents previously identified, and a visual review of the property. ;Our opinions and conclusions are fade in .accordance with-geker-ally accepted.'principles and practices of the geotechnical profession.
