HomeMy WebLinkAbout3.3 Town of Los Altos Hills April 8, 1998 Staff Report to the Planning Commission RE: SITE DEVELOPMENT PERMIT FOR A NEW RESIDENCE; LANDS OF HARARI; 12580 MIRALOMA WAY; File#6-98-ZP-SD. FROM: Susan Stevenson, Planner 55 APPROVED BY: Curtis S. Williams, Planning Dire for RECOMMENDATION That the Planning Commission EITHER: 1. Approve the requested Site Development Permit, subject to the attached conditions of approval; OR 2. Approve the requested permit, subject to the attached conditions, with modifications to condition #1 to either revise the patio exit from the lower level and/or to reduce the mass at the entry. BACKGROUND The subject property is located to the left at the end of Miraloma Way. There is no subdivision information on the creation of this lot, therefore, a certificate of compliance will be required with the approval of the new residence (see condition #?). The title report indicates that there are access easements along the northeast corner for private use by the neighbors. A new residence was approved on this site in January, 1997. The previous owners subsequently sold the property and a new residence is proposed. The previous points of concern were the extent of the second story and the plantings proposed (and installed) on the site. The current application does not include planting (to be reviewed at a Site Development Hearing) and has located the second story area and higher rooflines away from the neighbors that had concerns regarding views with the previous application. CODE REQUIREMENTS As required by Section 10-2.301 of the Site Development Ordinance, this application for a new residence has been forwarded to the Planning Commission for review and approval. Criteria for review from the Site Development Ordinance include grading, drainage, building siting, pathways, landscape screening and outdoor lighting. Zoning Code review encompasses compliance with floor and development area requirements, setbacks, height and parking. Planning Commission Lands of Harari April 8, 1998 Page 2 DISCUSSION Site Data: Net Lot Area: 1.031 acres Average Slope: 9.7% Lot Unit Factor: 1.031 Floor Area and Development Area: Area Max. Prop. Exist. Incrs. Remaining Devel. 15,465 14,200 0* 14,200 1,265 Floor 6,186 6,063 0* 6,063 123 *Existing floor and development area to be removed. Site and Architecture The applicant requests approval of a Site Development Permit for a new two story residence with 1,845 square feet on the second story, 2,528 square feet on the first floor and 822 square feet on the lower level. A 3 car garage with 868 square feet is proposed attached to the residence. The second story would cover 54% of the first story area (including the garage). The applicant has included a 1,710 square foot sport court to be approved with the plans. The neighboring properties along Miraloma Way are a combination of newer two story and older one story residences. The maximum height of the house on a vertical plane would be 26.5 feet, although the roof heights range from 16 to 18 feet at the south side of the residence to 24 feet at the garage. The height of the residence from the lowest to highest point would be 30 feet, as the basement area is counted toward the height and floor area of the residence. The height as indicated on the plans (25 feet) has been measured to the exterior grade rather than the building pad, which explains the discrepancy between the figures. It should be noted that the elevation drawings are not to scale and the heights are limited to those shown on the plans, not the scaled height. Story poles have been erected on the site outlining the new residence for the Commissioners' review. The exterior materials proposed for the residence are wood board siding and stone veneer with a composition shingle roofing and wood trim around the windows. The residence would be visible from Miraloma Way, although several of the existing plantings would help to screen the new residence. There are a number of architectural features, including the varying rooflines, bay windows, banding between the floors, the proposed mixture of materials and several indented areas of the proposed new residence, which would help to reduce the appearance of bulk of the house, especially from neighbors' views. The applicant has designed the residence with a steeply pitched roof which helps to conceal much of the second floor area. The area above the garage includes storage area within the roof that would not be included toward the floor area, although the height of the storage area to the roof is greater than 7 feet in some portions, in spite of the ceiling. Therefore, the area with an interior height greater than 7 feet to the roof would count as floor area. Staff has added a condition (#1) that the floor area of the storage space be reduced or added to the MFA. Planning Commission Lands of Harari April 8, 1998 Page 3 Entry Feature The entry feature at the front of the residence includes an arched element at the first floor level and an arched window with a gabled roof at the second story and overhang of the second story area. The combination of these elements gives the impression of a somewhat imposing two story feature at the entry. The front of the residence has limited visibility from the neighbors and the street, however, the Planning Commission could require that the applicant redesign the second floor master bedroom to be pulled back to match the walls of the remainder of the second floor on that elevation. Lower Level The lower level has been designed completely below natural grade. The exterior exit from the lower level is larger than the minimum required by the building code for a basement, therefore, the lower level area has been counted toward the maximum floor area. As the lower level does not meet the town's definition of a basement due to the exterior exit, the height of the residence has been measured from the lower level. The residence has been designed so that the 2 story portion of the house and the lower level does not overlap. Colors and Outdoor Lighting One skylight is proposed at the stairs to the second story, on a flat portion of the roof. Outdoor lighting has been shown on the floor plan, with one light shown at each exit and two at the front entry. Staff has included the standard condition (#10) for outdoor lighting, requiring that fixtures be approved by the Planning Department. Parking, Driveway, and Turnaround Three of the 4 required parking spaces would be located within the garage. The 4th space would be located at the driveway circle in front of the residence. All of the required spaces are proposed out of the setbacks and have adequate backup area for the spaces. The plans show that the majority of the driveway and turnaround circle have been designed out of the setback. No retaining walls are proposed for the new driveway although an 8 inch curb is proposed along the west side of the driveway. Grading and Drainage The plans indicate that the proposed project would include 1,360 cubic yards of cut and 435 cubic yards of fill. The majority of the cut appears to be proposed for the residence, as it is cut into the west side of the lot and the basement level is completely below natural grade. The finished floor of the center portion of the residence is a maximum of 2 feet above the natural grade at the front entry and cut 3 feet into the rear portion of the residence. The cut and fill heights, as well as the combined total heights, are generally consistent with the staff's guidelines for grading limitations for the proposed development on the property. The proposed basement level is cut a maximum of 11 feet into the natural grade to help lower the profile of the 2 story portions of the residence and to ensure conformance with the grading policy for fill for the rest of the residence and adjoining landings and patios. A retaining wall is shown at the exit of the lower level which would wrap around the dripline of the oak. The maximum height would be 9 feet and would gradually meet natural grade. A second retaining wall, shorter in length is shown on the other side of the patio,with similar heights. Planning Commission Lands of Harari April 8, 1998 Page 4 The patio at the exterior of the basement is proposed 10 feet below natural grade which does not comply with the Town's grading policy. The size of the patio is larger than the minimum exit size from a basement per UBC, therefore, the basement has been counted toward the floor area of the residence. The patio area is at the same elevation as the basement area and would not be visible from adjacent properties,however. The sport court is designed at natural grade at the northeast corner of the residence and is cut a maximum of 4 feet at the southwest corner of the court. No retaining walls are required for the court. The Engineering Department has reviewed the plans and has recommended conditions of approval as specified in Attachment 1. The majority of drainage from the house is designed to be directed to the northeast corner of the property and the drainage channel along Miraloma Way. Drainage from the basement is proposed to be outlet at the southeast corner of the property. Two area drains are proposed to outlet along the southerly setback line. The Engineering Department will review and approve the fmal 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. Trees There are 5 trees on the site plan which would be required to be removed with the construction of the driveway and patio areas. There is 1 heritage oak on the site which is proposed to be maintained, and an arborist's report has been submitted indicating that the oak tree is in fair condition. The report listed specific procedures to be utilized during construction of the residence. Staff has included a condition requiring that the arborist be on site at all times during construction and/or grading within the vicinity of the heritage oak tree and that a letter be submitted from the arborist stating the health of the tree and that any corrective treatment has been completed (condition#7) prior to fmal inspection. The 28 inch redwood and the 36 inch pine trees which are proposed to be removed with construction were labeled in poor condition and removal was suggested for these trees. There is one 10 inch oak tree which has not been shown on the plans which appears to be located in the center of the backup area for the garage parking spaces. Staff has included a condition of approval (condition #2) requiring that 3 oaks be planted with the required landscaping to replace the removed oak. The previous applicant had planted a number of redwoods on the site that had been required to be removed with the approval of the previous design. Staff has added a condition(#2) that the redwoods be removed prior to building plan submittal. Other Staff and Committee Recommendations The Pathways Committee has no recommendation for this project. A pathway fee should be required, however, per Section 10-2.608 of the Site Development Code, and condition #22 requires such payment prior to fmal building inspection. The Environmental Design Committee notes that any smaller oaks on the site should be saved. Staff has included a condition that all oaks be fenced if they are not proposed to be removed and that several replacement oaks be planted with the required landscape plan. Planning Commission Lands of Harari April 8, 1998 Page 5 The Santa Clara County Fire Department requires that the applicant install fire sprinklers to the residence to meet the required fire flow duration requirements. The turnaround shown on the plans does not meet the Fire Department's requirements for an emergency vehicle turnaround, therefore the applicant will be required to widen the leg of driveway from the turnaround to the garage spaces. Staff has conditioned the applicant to work with the Fire Department and staff to ensure compliance with the requirements. The address must be clearly shown on the residence and the width and vertical clearance of the driveway shall be maintained. Staff is available to answer any questions that the Commission or community may have. ATTACHMENTS: 1. Recommended conditions of approval; 2. Worksheet#2; 3.

OBSERVATIONS/DISCUSSION ,Species on Site: The following species of trees were observed: NO. GENUS SPECIES COMMON NAME PERCENTAGE OF TOTAL 1 Pinus sahiniana Digger Pine 33% 2 Sequoia sempervirens Coast Redwood 33% Arborist Report for Sealana &Associates Steve& Cathy Harari December 10,1997 12580 Miraloma Way, Los Altos Hills,CA Page-2 3 Quercus agrifolia Coast Live Oak 33% General Site Observations: The site is typical of a gently sloped hillside oak woodland being converted to a residential development. The woodland generally has an eastern exposure. Understory vegetation consisted primarily of grasses, and non-maintained domestic landscape plants. Trees within the site were generally found in stable condition with no significant pest or disease problems. Of the three trees inspected, only the Quercus agrifolia is thought to be a naturally occurring native. All trees within the site are now in need of professional pruning to (1) enhance safety, (2) sustain growth and development, and (3) to enhance aesthetics. Specific Tree Observations: TREE COMMON PHOTO OBSERVATIONS NO. NAME No. 1 Digger Pine 1-3 I'eight=50',Diameter(DBI-1)=9.61"(mean), Spread=32' Growing in an island situation on a gentle down-slope.Characteristic of this species is the multi-trunked habit. The tree is over-mature with a sparse crown. As a result of age and root constraints(surrounded by compacted roadway),the tree's vigor is characterized as"poor." Minor scale and aphid pests were noted. No root defects were observed. Co-dominance and Included bark(characteristic of this species)was noted in the trunk. Due to age, normal cracking and splits were noted in the scaffolds and branches. We observed a dead Pinus radiata(Monterey Pine)in close proximity which had succumb to Pine Pitch Canker disease. However we noted no significant indications of the disease on the Digger Pine. Summary: Age=Mature, Structure=Fair, Vigor=Poor Arborist Report for Sealana &Associates Steve & Cathy Harari December 10, 1997 12580 Miraloma Way, Los Altos Hills,CA Page-3 2 Coast 4-6 I'eight=40', Diameter(DBH)= 18.65"(mean), Spread=24' Redwood Growing in a bed area open to the cast,this mature species of redwood has a co-dominant trunk. The tree shows evidence of previous stress as indicated by chlorotic sparse foliage and poor annual shoot growth.Minor mite infestation was noted and evidence of a former Botryosphaeria dothidea infection was observed. The tree appears to have been suffering from drought-related stress as this species is classified as a high water using species. From this perspective,it is in conflict with the adjacent Quercus agrifolia which is classified as a very-low water using species. Additionally,the canopy of the adjacent Quercus is crowding the Sequoia. Summary: Age=Mature, Structure=Poor, Vigor=Poor 3 Coast Live 7-10 I-Leight=30',Diameter(DBI1)=25.7", Spread=32' Oak Growing in a bed area open to the east,this mature specimen is in good condition with good structure and no severe defects noted. As indicated above,the adjacent Redwood is in physical conflict as well as it has conflicting water requirements. Because of the crowded condition with the Redwood,the vegetation on the north side is sparse. The canopy of the tree overhangs the existing building approximately 6'. Minor co-dominance noted in the upper canopy with some included bark noted. Evidence of previous oak moth infestation noted. Minor girdling of root crown noted. Summary: Age=Mature, Structure=Fair, Vigor=Fair Impacts Related to Site Development, 1. Tree Removal - Based on the proposed site plan and construction plan provided by Robert Mowat & Associates, no tree removal is currently required. 2. Construction Activities - Direct impact to vegetation will occur in an even wider area due to movement of equipment and other construction activities. Physical injury to trees, especially damage to tree roots, could kill trees in a wider area. In addition, a significant amount of forest damage done during development results not from stress caused by Arborist Report for Sealana &Associates Steve & Cathy Harari December 10, 1997 12580 Miraloma Way, Los Altos Hills,CA Page-4 physical injury directly, but by creating conditions that favor destructive insects and diseases. The effects of construction on trees may be seen during development or shortly after the project is completed, or they may not become evident until years later. For example, bruising of bark may allow disease organisms to enter trees, and movement of soil during grading spread disease organisms. 3. Grading- Native oak trees are especially sensitive to damage from damage from construction. Movement of heavy equipment can compact soil, tear underground roots, and bruise bark. Grading can cause cutting of feeder foots that often extend beyond the outer ring of the tree canopy. Loading of earth or rock fill on top of roots may restrict water and oxygen to the roots and alter the flow of surface and subsurface water to the roots. Dust from grading may coat leaves and interfere with transpiration. Dumping and subsequent leaching of substances used in construction(oil, roofing compounds, paint, paint thinners, and herbicides) may harm trees. Based on topographic survey data, grading, and proposed landscaping plans, we see that trees most likely affected by cut/fill operations will be located closest to the proposed building site. Methods such as retaining walls, planter-liners, etc. should be utilized to avoid substantial grade change within the drip line of trees to be preserved. 4. Landscaping - The introduction of non-native, invasive plant species for residential landscaping may degrade remaining oak woodland habitat. In addition, mature oak trees may be killed by over watering from irrigated landscaping. RECOMMENDATIONS Based on this examination, the following recommendations are made: 1. Irrigation before and after root destruction: Trees which will have excavations within its dripline, or will have portions of its rootzone area filled, should be provided with supplemental irrigation to minimize the adverse impacts of stress. We recommend using low precipitation methods such as "ozze"-type soaker hoses. Slow flow soaker hoses must be placed at the dripline of affected trees. In those instances where root destruction has occurred, slow flow soaker hoses should be placed over the cut ends of the roots. Slow flow irrigation should be sufficient to percolate to a depth of 24". Depth of percolation should be checked with a soil probe or shovel. This procedure should start approximately four weeks before any grading will occur near the tree. Arborist Report for Sealana &Associates Steve& Cathy Harari December 10,1997 12580 Miraloma Way, Los Altos Hills,CA Page-5 Watering should be weekly to a depth of 24", using the method described above. Monthly irrigations during the dry season should occur until one year after construction is completed. 2. Fencing around trees during construction: A temporary fence shall be erected around each tree to be retained. This fence is ideally located outside of the dripline of each tree. Such a common fence should be erected at or beyond the drip lines of the trees and must be designed so as not easy for construction workers to remove or relocate. This fencing must be erected before any construction equipment enters the site, and must not be removed until final landscape grading is completed. It cannot be emphasized enough how important these fences are. Soil compaction and trenching through root zones are the major causes of tree stress in the post construction period. It should be explained to clearly to all contractors and workers on site that these fences are sacred. Trenching of any sort and for any reason must be planned to avoid traversing areas within the tree drip lines. This should include planning for utility or irrigation lines. Plans should show specific locations and sizes of trenches, if possible. 3. Protection from sluffing during grading operations: In preservation areas downhill from proposed grading, all efforts must be employed to prevent the sluffing of soil onto the trunks of preserved tree species. Additional installations of snow fencing should be installed if any sluffing should occur within the drip lines of trees identified for preservation. 4. Pruning and other tree care operations: For trees remaining on site pruning is required to (1) enhance safety, (2) sustain growth and development, and (3) to enhance aesthetics. 5. Special Care for Coast Live Oak Tree: Once established, native oaks require little or no supplemental irrigation. In fact, they do best in non-irrigated soils.' This is because oak roots, particularly those originating at the Caprile, Janet L. Guidelines for Development Around Old Oaks, University of California Cooperative Extension, Contra Costa County Arborist Report for Sealana &Associates Steve& Cathy Harari December 10, 1997 12580 Miraloma Way, Los Altos Hills,CA Page-6 base of the trunk (root crown), arc susceptible to root-disease fungi when exposed to prolonged moisture during the summer. These fungi arc normally inactive in dry soil, but proliferate under the warm, moist conditions created when frequent summer water is applied. (Other species of trees are less susceptible to these fungi because they have evolved where summer soil moisture is high.) Oaks weakened by the loss of roots or root function are particularly susceptible to root pathogens and other pests. Frequent summer irrigation, particularly near the root crown, is likely to cause root decay which, over time, may destroy the roots, killing the tree or causing a hazardous situation. Therefore, irrigation for lawns, ground covers or other ornamental vegetation should be avoided or, at the very least, kept well away from the trunk. 6. Future Tree Removal: As discussed herein, Tree#1 (Digger Pine) is very mature and beginning a natural decline. Due to its moderate hazard potential, thistree is recommended for removal within five years. Also as discussed herein, Tree#2 (Sequoia) is in conflict with the higher-valued Coast Live Oak Tree (Tree#3). This conflict is both physical (due to crowding) and horticultural (due to conflicting water requirements). As a result, it is recommended that the Sequoia he removed within the next 10 years are replaced with a lower-water-using species in a location which will not adversely affect the growth and development of the Quercus.
