BACKGROUND The subject property is located on the west side of Julietta Lane near the end of the cul de sac. The surrounding uses include single-family homes on adjacent parcels to the west, north, and, south, and east. The applicant proposes to demolish an existing single story residence, construct a new single story residence with basement, and retain the existing swimming pool. CODE REQUIREMENTS As required by Section 10-2.301 (c) of the Municipal Code, this application for a new residence with a basement has been forwarded to the Planning Commission for review. The Zoning and Site Development sections of the Municipal Code are used to evaluate proposed projects including floor and development area limitations, grading, drainage, height, setbacks, visibility, and parking requirements. DISCUSSION Site Data: Gross Lot Area: 1.48 acres Net Lot Area: 1.42 acres Average Slope: 21.07% Lot Unit Factor: 1.084 Staff Report to the Planning Commission Lands of Ilnicki 27349 Juliette Lane February 4, 2010 Page 2 of 14 Floor Area and Development Area: Area (sgft.) Maximum Existing Proposed Increase Remaining Development 11,760 6,939 11,300 4,361 460 Floor 5,904 3,847 5,373 1,526 531 . (Basement 3,368) to and Architecture The applicant is requesting approval of a Site Development Permit to construct a 5,373 square foot single story residence with a 3,368 square foot basement. The applicant plans to retain the existing 720 square foot swimming pool. The new residence will be located in the same vicinity as the existing residence on the southeastern portion of the property. The area of the proposed residence is characterized by gentle to moderately steep north facing slopes. The average slope of the property is 21.07%. The new residence meets the setback, height, floor area, and development area requirements established in Title 10, Zoning and Site Development, of the Los Altos Hills Municipal Code. The new residence is located a minimum of 40' from the east (front) property line, 70' from the north (side) property line, 36' from the south (side) property line, and 184' from the west (rear) property line. The maximum building height on a vertical plane is 23' and the maximum overall height of the building (including chimneys and appurtenances) from the lowest point to the highest point is 34'6". Proposed exterior materials consist of stucco exterior with stone veneer and tile roof. The basement level of the new residence has 3,368 square feet of area which includes a guest room, sauna, laundry, walk in closet, recreation room, storage, wine closet, and a three (3) car garage. The basement is wholly underground (except for access into the garage and 230 square feet along the northern side of the residence which does not qualify as basement per. the Towns Basement Ordinance) and exempt from floor area calculations pursuant to Section 10-1.208 of the Municipal Code. The main level has 5,049 square feet of living space with a great room, kitchen, master bedroom with walk in closet, a secondary master bedroom with walk in closet, and two bedroom/study rooms, powder room, and a bathroom. Driveway & Parking The existing driveway will be removed and replaced with a new driveway which will run along the north side property line leading into a basement garage. Staff Report to the Planning Commission Lands of Ilnicki 27349 Julietta Lane February 4, 2010 Page 3 of 14 Pursuant to Section 10-1.601 of the Municipal Code, a total of four (4) parking spaces are required. A three (3) car basement garage is proposed along the northern property line and one (1) outdoor parking space located outside of the property line setbacks on the north side of the residence. Outdoor Lighting The applicant is proposing eighteen (18) can downlights in the eaves surrounding the house and four (4) column lantern downlights located on the exterior of the garage (Lighting plan sheet A0.7). Staff has included condition #11 for outdoor lighting, requiring that fixtures be down shielded or frosted glass, low wattage, and shall not encroach or reflect on adjacent properties. The applicant has submitted lighting specifications indicating that all proposed fixtures will be shielded, downlights, or have frosted glass. Trees & Landscaping Nine (9) pine trees are to be removed for the new construction. The applicant has provided an arborist report prepared by McClenahan Consulting, LLC dated December 8, 2009 for six (6) heritage oak trees within the vicinity of the proposed construction. The trees are expected to survive the construction with the protection measures suggested by the arborist (Attachment 8). To ensure that all remaining significant trees will be protected throughout the construction period, staff has included condition of approval #5 requiring that the trees within the vicinity of the construction be fenced for protection. A landscape screening and erosion control plan will be required after framing of the new residence (Condition of approval 43). Furthermore, any landscaping required for screening or erosion control will be required to be planted prior to final inspection, and a maintenance deposit to ensure viability of plantings will be collected prior to final inspection. Drainage Water runoff generated from the new development will be collected and carried to an on-site storm water retention system located at the west side of the property. The water is then metered out slowly into an energy dissipater. Pursuant to Section 10-2.503, Drainage Facilities Standards, of the Municipal Code, the Engineering Department has reviewed and determined that the proposed drainage design complies with Town requirements. The Engineering Department will review and approve the final drainage plan prior to acceptance of plans for building plan check. Final "as -built" grading and drainage will be inspected by the Engineering Department, and any deficiencies will be required to be corrected prior to final inspection. Staff Report to the Planning Commission Lands of Ilnicki 27349 Julietta Lane February 4, 2010 Page 4 of 14 Grading Policy Exception Total grading quantities for this project -include 1,435 cubic yards of cut for the basement and new residence. The Engineering Department has reviewed the proposed grading plan and concluded that it is not in conformance with the Town's Grading Policy. The applicant is requesting a Grading Policy exception for up to 10 feet of cut where 4 feet is allowed for yard areas, in order to create a 4 foot wide walkway around the south side of the new residence. The total area for the proposed cut over 4 feet is 1,625 square feet. The applicant is proposing three (3) retaining walls which will be terraced with a maximum height of 5' in order to avoid a single 10'-12' tall wall. The Grading Policy is intended to be used by staff in evaluating and making recommendations to the Planning Commission and/or City Council regarding site development applications, and for guiding applicants. Individual sites may dictate a need to deviate from the criteria, to the extent permitted by the Planning Commission and/or City Council. If the proposed grading were to occur on a hillside or ridgeline property, the excavation for the side yard would result in massive retaining walls with high visibility and substantial visual alteration of the natural terrain in violation of Section 10-2.702.c of the Site Development Code. However, in this case, the cut occurs along the side of the residence and will not be visible from off-site and will not result in the removal of vegetation. If the Commission decides to approve the Grading Policy Exception for the side yard area, Findings of Approval in Attachment 2 should be cited. Staff Report to the Planning Commission Lands of llnicki 27349 Julietta Lane February 4, 2010 Page 5 of 14 Neighbor Concerns To date, staff has received one (1) email from the neighbor at 27359 Julietta Lane regarding concerns for the length of time of the construction and construction parking (Attachment 3). The applicant has since spoken to the neighbor regarding their concerns. Fire Department Review The Santa Clara County Fire Department has reviewed the proposal and is requiring a sprinkler system throughout all portions of the new residence (Attachment 4). Geotechnical Review The Town's geotechnical consultant Cotton, Shires & Associates, Inc., has reviewed the soil and foundation report prepared by GeoForensics Inc., dated November 12, 2009 and recommends approval of the permit based on conditions 15 a & b (Attachment 5). Green Building Ordinance This project is required to comply with the Town's Green Building Ordinance. The new residence is designed to achieve 99 points in Build it Green's GreenPoint Rated program. Committee Review The Pathways Committee recommends dedication of an additional pathway easement to allow full pathway access in the alignment currently occupied by the emergency access road (Condition #24). The Environmental Design and Protection Committee have no concerns (Attachment 7). CEQA STATUS The project is categorically exempt under CEQA per Sections 15303 (a) ATTACHMENTS 1.

The primary concerns that we have are as follows: Julietta Lane is a single car's width in some places -- particularly in front of the Ilniki's house. We would like for there to be a plan in place so that the road will not be blocked. Specifically, where on the Ilniki's property will construction vehicles be parked when in use and when not in use? Where will the construction workers park their cars every day, as there is no on -street parking? We have a child with a medical issue -- so it is critical to us that the road never be blocked to entry or egress. Without some careful planning, given the narrowness of the road, any construction on this part of Julietta is likely to block our ability to get into and out of the house -- In an emergency, this becomes untenable. When the Ilniki's house is demolished, will there be any steps taken to mitigate asbestos dust and dust from any other toxic materials? We live right next door and we have children -- It looks like an older house, so I must assume there were asbestos materials utilized in its construction, as was usual for the time period in which it was built. Thank you for addressing this safety concern. How long does the builder anticipate a great deal of working noise on the site? Beginning April 15? 1 am a novelist and I work at home -- The largest reason we moved to the neighborhood was for the quiet environment in which I could work. Thanks very much for addressing these questions, Nicole. I look forward to hearing from you. Most sincerely, . Lane MacWilliams 1/27/2010 From: Andrew Young [mailto:ayoung@ybarchitects.com] Sent: Thursday, January 28, 2010 4:58 PM To: lanemacwilliams@aol.com; Nicole Horvitz Cc: ski_ilnicki@agilent.com Subject: RE: Julietta Lane project Hello Lane and Ken MacWilliams, I am the architect working with your neighbors Viola and Ski Ilnicki on their new home. Nicole Horwitz forwarded me your e-mail with your comments and concerns for their project. I spoke with Ski this morning and I understand that you met with him yesterday to discuss his project as well as your concerns. I trust that Ski shared with you the proposed "Construction Staging Plan" for his project, in which we have delineated the proposed locations for all of the construction activities on site (i.e. contractor parking, equipment and material storage, job trailer, toilet facilities, debri box and clean-up areas, etc.). Fortunately there is enough space on the property to accommodate the construction support without the need to encroach onto the public right of way. The project plans include construction fencing and all measures required by the Town to protect neighbors from unnecessary inconveniences and hardships. I believe that Ski also discussed the construction scheduling with you both and we would be happy to review this with you again once all of the permits are approved and the contractor selected. Once our clients have selected a contractor the specifics of start dates, demolition, excavation, framing, etc. will be better understood. At that time we will have a more exact idea of the schedule for the various phases of the construction, and would be happy to share that with you. We also wanted to assure you that all of the demolition and debri removal (i.e. asbestos) will conform to the requirements of the Town of Los Altos Hills and the State of California. As part of the building permit approval process the contractor is required to obtain a "J Number" from the Bay Area Quality Management District that oversees the proper removal and disposal of any toxic materials. We can assure you that all of these required and proper measures of public protections will be incorporated and adhered to within the construction process. Finally I would like to extend to you both my own and Ski's personal commitment to remaining accessible throughout the construction process. My cell and office numbers are below and as soon as we have selected a contractor we can also provide you with the superintendent's direct line. If at any time you have any concerns or questions, please feel free to contact any or all of us and we shall make every effort to address your concerns. I would be happy to meet with you personally if you have any further questions. Regards, Andrew E. Young YOUNG AND BORLIK ARCHITECTS, Inc.

CONSULTING ENGINEERS AND GEOLOGISTS RECEIVED November 12, 2009 L0219 e ` ' 2029 TOWN OF LOS RMS HILLS TO: Nicole Horvitz Planning Department TOWN OF LOS ALTOS HILLS 26379 Fremont Road Los Altos Hills, California 94022 SUBJECT: Geotechnical Peer Review RE: llnicki, New Residence 212-09-ZP-SD-GD 27349 Juliette Lane At your request, we have completed a geotechnical peer review of the subject application using: • Geotechnical Investigation (report) prepared by GeoForensics Inc., dated September 1, 2009; • Architectural Plans (16 sheets, various scales) prepared by Young and Borlik, dated September 29, 2009; and • Grading and Drainage Plan, Erosion Control, Sections, and Details (10 sheets, various scales) prepared by Lead & Braze Engineering, dated October 15, 2009. . In addition, we have reviewed pertinent maps and reports from our office files and inspected site conditions. Inspection was limited to vantage points near the front of the residence due to posted dog sign. DISCUSSION The applicant proposes to construct a new residence with basement in the southeastern portion of the property. We understand that the existing residence is to be demolished. Construction of a new driveway is proposed extending from Julietta Lane Northern California Office 330 Village Lane Los Gatos, CA 95030-7218 (408) 354-5542 o Fax (408) 354-1852 e-mail: losgatos@cottonshires.com www.cottonshires.com Central California Office 6417 Dogtown Road San Andreas, CA 95249-9640 (209) 736-4252 o Fax (209) 736-1212 e-mail: cottonshires@starband.net Nicole Horvitz November 12, 2009 Page 2 L0219 at the northeastern corner of the property. Proposed grading includes a reported 2,425 cubic yards of cut. Three terraced retaining walls are proposed for construction near the southern portion of the residence. Construction of other retaining walls is proposed along portions of the driveway entrance to the garage. The residence will be served by a sanitary sewer. Drainage detention and discharge structures are proposed in the western portion of the property. SITE CONDITIONS The vicinity of the proposed residence is generally characterized by gentle to moderately steep (15 to 20 percent) north -facing slopes. A fill prism was observed beneath the existing driveway to the north of the residence. Fill slopes are moderately steep with steeper slopes displaying signs of downslope creep. The existing driveway asphalt showed signs of distress, with cracking likely related to the underlying fill and potentially expansive earth materials. The site is underlain, at depth, by mapped greenstone bedrock of the Franciscan Complex confirmed by exploratory borings. The bedrock is mantled by silty clay (colluvial soil and fill) with a high potential for expansion (measured PI of 38). The potentially active Berrocal fault has been mapped approximately 1,100 feet northeast of the property. CONCLUSIONS AND RECOMMENDED ACTION The proposed new residence appears to be constrained by areas of existing fill materials, soils with a high expansion potential, and anticipated very strong seismic ground shaking. The Project Geotechnical Consultant has completed an investigation of site conditions consistent with prevailing standards and has recommended appropriate geotechnical design criteria to address identified site constraints. We do not have geotechnical objections to the proposed layout of site improvements. However, we recommend that the Project Geotechnical Consultant evaluate geotechnical aspects of proposed new drainage detention and discharge facilities to be located in the western portion of the property. Geotechnical design criteria for terraced retaining walls south of the residence should also be clarified. We recommend that the following conditions be attached to geotechnical approval of permit applications for the project. 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 COTTON, SHIRES AND ASSOCIATES, INC. Nicole Horvitz Page 3 November 12, 2009 L0219 foundations and retaining walls) to ensure that their recommendations have been properly incorporated. In addition, the consultant should specifically evaluate geotechnical aspects of the following: • Proposed storm drainage facilities including dissipaters and detention facilities. • The consultant should evaluate the configuration of proposed terraced retaining walls south of the residence, confirm appropriate foundation 11,Te and address whether walls should be designed considering surcharge loading due to the close wall alignments. The results of the plan review should be summarized by the geotechnical consultant in a letter and submitted to the Town Engineer prior to acceptance of documentation for building permit plan -check. 2. Geotechnical Field Inspection — The geotechnical consultant should inspect, test (as needed), and approve all geotechnical aspects of the project construction. The inspections should include, but not necessarily be limited to: site preparation and grading, site surface and subsurface drainage improvements, excavations for foundations and retaining walls prior to the placement of steel and concrete. The consultant should inspect the drilling of foundation piers to verify adequate embedment into supporting materials. 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 geotechnical peer review has been performed to provide technical advice to assist the Town with 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 made in accordance with generally accepted principles COTTON, SHIRES ANIS ASSOCIATES, INC.

ADMINISTRATIVE Co -Chairman Nick Dunckel called the meeting to order at 7:05 PM Members present: Anna Brunzell, Nick Dunckel, Ann Duwe, Eileen Gibbons, Bill Silver, Bob Stutz, Tim Warner, Sue Welch Members absent: Courtenay Corrigan, Chris Vargas Associate Members present: Nancy Ginzton Council Members present: Breene Kerr and Ginger Summit Members of the public present: Ciesinskis, owners of 26435 Ascension Drive The agenda was approved as amended below. 2. COMMUNICATIONS FROM THE FLOOR. None 3. PROPERTIES FOR REVIEW A. The following properties were reviewed for pathway recommendations: i. 26435 Ascension Drive (Lands of Ciesinskil. The reason for pathway review is construction of a new residence. The Ciesinskis, the homeowners, were present at the meeting. The lot is located on the north side of Ascension; the road makes a near -right angle turn here and follows two sides of the property. The property slopes up steeply from the roadside and construction of a pathway would be difficult. Ascension is a one- sided road and PWC maps show the opposite side is preferred for a roadside pathway. Bill Silver moved that a pathway in -lieu fee be collected from the owners of 26435 Ascension Drive. Anna Brunzell seconded. The vote was unanimously in favor. 27349 Julietta Lane (Lands of Ilnicki), The reason for pathway review is construction of a new residence. The property is on the west side of Julietta, near the end of this cul-de-sac serving approximately 13 properties. The Town already holds easements along the north and west sides of the property. Off-road pathways along these easements provide important connections to Chaparral Way to the south and to Byrne Preserve (via Deer Springs Way and Byrne Park Lane) to the north. The existing 10 -foot "path" easement on the north side of the property runs along the south side of a 20 -foot wide asphalt emergency access easement. On the west side of the property there are an existing 20 -foot fire road easement, a 10 -foot "equestrian" easement centered on the centerline of the fire road easement, and a separate 10 -foot "path" easement. Part of this equestrian easement appears to be outside the actual emergency access road. Most of the "path" easement appears to lie outside the actual fire road. Near the NW corner of the property, a pathway easement turns south and follows the full length of the western property boundary and joins a pathway easement on the adjacent property (27359 Julietta) that connects to Chaparral Way. The PWC discussed the importance of these connections for both pedestrians and equestrians between Chaparral Way, Deer Springs Way, and Juliette Way and the importance of clarifying all the easements on this property to assure continued public access. Ann Duwe moved that the Town clarify the language describing the easements on 27349 Julietta Way to confer full pathway access in the alignment currently occupied by the emergency access road. The PWC recommends removing the part of the easement on the north side that is outside the emergency road. The easement should include the dogleg heading towards Deer Springs Way. Anna Brunzell seconded. The vote was unanimously in favor.

A new home is to be built on this site. As requested, a survey of the possibly affected significant trees on site and a tree protection plan will be included in this report. Summary The trees on the site that may be affected by the proposed construction are a mix of native oaks and imported cork oaks. The oaks on the site are in fair to good condition with no excellent trees. Trees #12 and #14 will have a retaining wall at the edge of the oaks dripline. Impacts to these trees are expected to be minor to moderate. Root loss is expected to be less than 25 percent well within expectable limits. Trees# 44 and #45 are cork oaks; trees #46 and #56 are coast live oaks. Two water retention storage areas and the drain pipes that lead to the pit will be slightly within the driplines of the oaks. The location of the retention pit and its pipes will be at the edge of the driplines of the oaks. Root damage from the excavation is expected to be insignificant to minor with no major root cutting. With proper tree protection impacts to all of the oaks outlined in this report will be within acceptable levels. Methodology The lot was inspected from the ground. The trees were located on a map provided by you. Each tree was assigned an identification number. This number was inscribed on a metal foil tag and nailed to the tree near the ground. The trees were then measured for diameter at 48 inches above ground level (diameter standard height). A condition rating of 1 — 100 was assigned to each tree representing form and vitality using the following scale: Mr. Ski Ilnicki Page 2 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. The location of each tree was described. Lastly, a comments section is provided. Tree Description/Observation 12: Coast live oak (Quercus agrifolia) Diameter: 25.5"Low branching Height: 40' Spread: 45' Condition: 60- Fair Location: South east of existing house Observation: Foliar canopy is shaded and competes with adjacent pines and oak. The removal of the pines will enhance the growing environment of the trees foliar canopy. The proposed terraced retaining wall will impact less than 25 percent of the lateral root environment. Any excavation within TPZ of 15 -feet must be accomplished by hand digging. A qualified arborist must supervise any cutting of roots greater than one inch in diameter. 14: Coast live oak (Quercus agrifolia) Diameter: 25.6, 16.2 Multi trunk Height: 35' Spread: 35' Condition: 60- Fair Location: South east of existing house Observation: Foliar canopy is shaded and competes with adjacent pines. Decay is visible on low trunk. Multi trunk growth habit creates an inherent structural defect. The proposed terraced retaining wall will impact less than 25 percent of the lateral root environment. Any excavation within TPZ of 15 -feet must be accomplished by hand digging. A qualified arborist must supervise any cutting of roots greater than one inch in diameter. 44: Cork oak (Quercus suber) Diameter: 26.1" Multi @ 5 feet Height: 35' Spread: 45' Condition: 65 - Fair Location: West of house Observation: The oak has fair form with multi leaders at 5 feet and fair crotch formations. Vigor is fair with normal shoot growth for the species. Abundance of deadwood in the lower canopy of the tree. Root loss from excavation will be less than 20 percent. Any excavation within the TPZ of 15 feet must be accomplished by hand digging. A qualified arborist must supervise any cutting of roots greater than one inch in diameter. Mr. Ski I1nicki Page 3 45: Cork oak (Quercus suber) Diameter: 9.7", 9.4" Multi leader @ 3 feet Height: 30' Spread: 35' Condition: 50 - Fair Location: West of house Observation: The oak has fair form with multi leaders at 5 feet and fair crotch formations. Vigor is fair with normal shoot growth for the species. Abundance of lower deadwood. Root loss from excavation will be less than 20 percent. Any excavation within the TPZ of 15 feet must be accomplished by hand digging. A qualified arborist must supervise any cutting of roots greater than one inch in diameter. 46: Coast live oak (Quercus agrifolia) Diameter: 18.2" Single trunk, suppressed Height: 40' Spread: 35' Condition: 60 - Fair Location: West of house Observation: The oak is suppressed by oak #44 and leans west. The tree is codominant at 10 feet with a fair crotch formation. Vigor is fair with normal shoot growth for the species. Abundance of lower deadwood. Root loss from excavation will be less than 10 percent. Any excavation within the TPZ of 15 feet must be accomplished by hand digging. A qualified arborist must supervise any cutting of roots greater than one inch in diameter. 56: Coast live oak (Quercus agrifolia) Diameter: 41.6" @1' Low branching Height: 50' Spread: 70' Condition: 70 - Good Location: West of house Observation: The tree is codominant at 2 feet with fair crotch formations. The oak has a low branching form with heavy'lateral limbs. The vigor is good with normal shoot growth for the species. Root loss from excavation will be less than 20 percent. Any excavation within the TPZ of 20 feet must be accomplished by hand digging. A qualified arborist must supervise any cutting of roots greater than one inch in diameter. 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. The spreading of chips will help to reduce compaction and improve soil structure. The installation of the landscape buffer of chips will be critical for the root zone of the oaks. Mr. Ski Ilnicki Page 4 Root Cutting Any roots to be cut shall be monitored and documented. Large roots (over 1" 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. Extensive root cutting is not expected -on this site. Irrigation The oaks on this site should not need any warm season irrigation. If roots of the trees are cut, irrigation may be recommended by the site arborist. Irrigation would consist of flooding the root zone with enough water to wet the entire root area. Treatment with Agri -Fos to aid in prevention of Sudden Oak Death is recommended in fall annually for Live oaks. Trenching Trenching for irrigation, drainage, electrical or any other reason shall be done by hand when inside the dripline of a protected tree. Any excavation within 5 times the diameter of the tree should be done by hand and observed by the site arborist. 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 information included in this report is believed to be true and based on sound arboricultural principles and practices. We thank you for the opportunity to be of assistance in your tree preservation concerns.

Kielty' �1' Certified Arborist, WE -0476A Member, American Society of Consulting Arborists Mr. Ski Ilnicki Page 5 ARBORIST DISCLOSURE STATEMENT Arborists are tree specialists who use their education, knowledge, training and experience to examine trees, recommend measures to enhance the beauty and health of trees, and attempt to reduce the risk of living near trees. Clients may choose to accept or disregard the recommendations of the arborist, or seek additional advice. Arborists cannot detect every condition that could possibly lead to the structural failure of a tree. Trees are living organisms that fail in ways we do not fully understand. Conditions are often hidden within trees and below ground. Arborists cannot guarantee that a tree will be healthy or safe under all circumstances, or for a specified period of time. Likewise, remedial treatments, like a medicine, cannot be guaranteed. Treatment, pruning, and removal of trees may involve considerations beyond the scope of the arborist's services such as property boundaries, property ownership, site lines, disputes between neighbors, landlord -tenant matters, etc. Arborists cannot take such issues into account unless complete and accurate information is given to the arborist. The person hiring the arborist accepts full responsibility for authorizing the recommended treatment or remedial measures. Trees can be managed, but they cannot be controlled. To live near a tree is to accept some degree of risk. The only way to eliminate all risks is to eliminate all trees. Arborist: Kevin R.

Section 10-2.703(a) requires: "Type H foundations — step -on -contour, daylight, pole foundations, or a combination thereof — shall be used on building sites with natural slopes in excess of fourteen percent (14%)." Intent• The purpose of this policy is to outline desired criteria for grading which assure that construction retains the existing contours and basic landform of the site to the greatest extent feasible. It is also intended that the policy provide guidance for "stepping" structures down sloped hillsides, and emphasizes cut to lower the profile of structures over fill or foundation walls, which tend to raise the profile of the structure. While balanced cut and fill is desirable to minimize import or export of soil, to or from a site, it is recognized that the Town's policies and the guidelines below may encourage export as cut is generally preferred over fill. These policies are intended to be used by staff in evaluation and malting recommendations to the Planning Commission and/or City Council regarding site development applications, and as guidance for applicants. Individual sites may dictate a need to deviate from the criteria, to the extent permitted by the Planning Commission and/or City Council. Grading Policy Page 2 Polic . 1. Cuts and fills in excess of the following levels generally will be considered excessive and contrary to Town ordinances and policies to grade only to the minimum extent necessary to accommodate structures and to site structures consistent with slope contours, i.e., "step down" the hill*: Cut Fill House 8'** 3' Accessory Bldg. 4' 3' Tennis Court 6' 3' Pool 4'*** 3' Driveways 4' 3' Other (decks, yards) 43 3 * Combined depths of cut plus fill for development other than the main residence should be limited to 6 feet, except that for tennis courts out plus fill may be permitted up to a maximum of 8 feet. ** Excludes basements meeting Code definition. *** Excludes excavation for pool. 2. The height of the lowest finished floor(s) of a structure should generally not be set in excess of three (3) feet above the existing grade, to assure that structures step with the slope. 3. Driveway cut may be increased up to a maximum of eight feet (8D for the portion of the driveway or backup area which is adjacent to a garage that has been lowered with a similar amount of cut. . 4. Cut and/or fill for drainage shall be limited consistent with the guidelines set forth above for each type of structure, but shall be the minimum grading needed for drainage purposes, as determined by the City Engineer.

Daylighted basements shall comply with all height and setback requirements of this ordinance. Basements including cellars and bunkers, which are not located within the footprint of the building above, may be permitted by the Planning Commission when it finds that such structures do not encroach in setbacks, are a minimum of 18 inches below natural grade, are wholly underground except for required exiting, lighting and ventilation and are counted as development area except when placed under a surface already counted as development area. Note: Daylighted basements shall comply -with the Town's grading policy. Ae Grading Policy is used by staff in evaluating and making .recommendations to the Planning Commission and/or City Council regarding site development applications, . and as guidance for applicants. Individual sites may dictate a need to deviate from the criteria, to the extent permitted by the Planning Commission and/or City Council. Floor Area Deimition "Floor area" shall mean the gross horizontal area of the several floors of all buildings, including garage space and carport space, measured to the outside of exterior walls. Floor area is counted twice when the vertical distance between the upper surface of the floor, and the upper surface of the floor or the underside of the roof directly above it, is greater than seventeen (IT) feet. That portion of an attic is considered floor area when the distance between the upper surface of the attic floor and the underside of the roof above it is seven (T) feet in height. For the purposes of this definition, all attic spaces are considered to have floor surfaces. Area meeting the definition of a basement is exempted from floor area.
