FROM: Susan Manca,Planner Syn. APPROVED BY: Curtis S. Williams,Planning Direct RECOMMENDATION That the Planning Commission EITHER: 1. Recommend approval of the requested Site Development Permit and the modification to the subdivision conditions of approval, subject to the attached conditions of approval; OR 2. Direct the applicant to redesign the house to reduce the height of the cut proposed adjacent to the garage and follow more closely with the natural slope, returning to the Planning Commission for further review. BACKGROUND The subject property is located on the northwest side of the Matadero Creek Lane and Matadero Creek Court intersection. The parcel was created with a 20 lot subdivision (Tract 7187) that was recorded in 1981. The property is currently vacant. There is an open space easement along the east portion of the lot, a conservation easement located in the southwest corner, and a landscape easement to .the south of the conservation easement. The Matadero Creek Subdivision included many conditions of approval which limited development below that allowed by the Municipal Code. The MDA was calculated specifically for each lot based on the amount of area which was free of easements. In addition, a maximum building coverage and a maximum elevation of the building were set for each lot. Unlike other subdivisions in the Town, the Matadero Creek Subdivision required that the buildings be sited in the building site circle as shown on the Tentative Map. Amendments to the conditions in later years allowed for additional development area on specific lots. In 1996 the City Council approved the owner's application to modify the conditions of approval of the Matadero Creek subdivision to relocate the access of the property from the south side of the lot to the east side, as is shown on the plans. At that time, only the location of the access was reviewed. Planning Commission January 14, 1998 Lands of Rutner Page 2 CODE REQUIREMENTS According to Section 10-2.301 of the Site Development Code, all new residences are to be reviewed by the Planning Commission. Generally, the sections of the Zoning and Site Development Codes utilized to evaluate new homes include floor and development area limitations, grading, height, setbacks, visibility, and parking requirements. In addition to the Zoning and Site Development Codes, the conditions of approval of the subdivision require that Building Coverage be reviewed as well as compatibility of size and architectural design with the existing houses within the subdivision. The conditions of the subdivision created an architectural review board which has reviewed and approved the design of the proposed residence, including the proposed map amendment to modify allowable development area. Section 9-1.1210 of the Subdivision Code allows for Final Map Amendments if the City Council fords that there are changes in circumstances which no longer make any or all of the conditions of the map appropriate and that the modifications do not impose additional burdens on the property owner. Amendments to a final map must be reviewed through the same process set out for the approval of tentative maps.

Site and Architecture The applicant requests approval of a Site Development Permit for a new two story residence with a basement. The neighboring properties within the subdivision are a combination of larger two story and one story residences. The maximum height of the house on a vertical plane would be 25'A feet, although the roof heights range from 17 to 251/4 feet at different areas of the house. The height of the Planning Commission January 14, 1998 Lands of Rutner Page 3 residence from the lowest to highest point would be 28 feet, as the house is located in an area of approximately 20 percent slope and the roof line somewhat steps down with the slope. Story poles have been erected on the site outlining the new residence for the Commissioners' review. The exterior materials proposed for the residence are stucco with a concrete tile roof and led.gestone veneer accents. The residence would be visible from residences along Page Mill Road. The applicant has designed the residence lower on the hill and has designed the finished floor cut a maximum of 10 feet into the hill to lower the overall elevation of the new residence. In addition, there are a number of architectural features, including the varying rooflines, bay windows, second story balconies and the number of indented areas of the proposed new residence, which would help to reduce the appearance of bulk of the house. Second Unit The second unit is attached to the main house, at the southeast of the proposed garages, with its own entrance. The unit is proposed to be 418 square feet with an interior stairway to the basement. The unit would include a kitchen, living area and a complete bathroom. Pool House The pool house is proposed to be located at the same elevation as the pool. A retaining wall is designed into the rear of the building, as it is cut into the hill. The finished floor is proposed to be cut a maximum of 4 feet and the fill is limited to 2 feet, meeting the Town's grading policy. The maximum height of the building is 131/2 feet, and the roofline matches that of the main house. The unit includes a bar, living area and a complete bathroom. Condition #7 requires that the applicant file a deed restriction with the Town stating that the pool house will not be utilized as a second unit. Outdoor Lighting Two skylights are proposed along the rear roof of the new residence. Outdoor lighting has been shown on sheet 1 of the plans. Lighting appears to be minimal, with one light at each exit. Staff has included the standard condition (#10) for outdoor lighting, requiring that fixtures be downshielded and that all locations be approved by the Planning Department. Parking, Driveway, and Turnaround All of the four required parking spaces for the residence would be located within the garages with a fifth space for the second unit located to the east of the residence, along the driveway. The plans show that the garages are each 2 feet too narrow to meet the code requirement for a 2 car garage. Condition #1 requires that the garage spaces be reconfigured so that both garages have a minimum of 20 foot widths. Subsequently, the proposed development area would need to be increased by approximately 80 square feet. All of the required parking spaces are proposed out of the setbacks and have adequate backup area for the spaces.No retaining walls are proposed for the new driveway. Due to the long driveway proposed, the Fire Department has required a turnaround on site. The applicant has designed the turnaround to work with the required turnaround for Planning Commission January 14, 1998 Lands of Rutner Page 4 the garage space, with an additional area to be constructed of grasscells, which would be counted at 10 percent of the coverage toward the MDA (see worksheet#2). Grading The plans indicate that the proposed project would include 3,450 cubic yards of cut and 335 cubic yards of fill. The cut and fill heights, as well as the combined total heights, are generally consistent with the Town's guidelines for grading limitations for the proposed development on the property except in the nanny unit next to the garage. Specifically, the finished floor at the southeast corner of the residence is proposed to be 10 feet below natural grade, whereas the grading policy limits cut for the main residence to 8 feet maximum. The applicant has indicated that the reason that the development has been cut further into the hillside than the guidelines suggest is to obtain a low elevation to maintain views from across Page Mill Road. The majority of the house is at the same finished floor elevation of 520 feet. The Town advised the applicant to raise the northeast section of the house to better follow the natural contours of the lot. The applicant indicated that the front had been designed at the same level to allow adequate drainage around the north side of the residence and to lower the house to minimize view impact, which was a primary concern of the Architectural Committee. The southwest portion of the residence has been stepped down 2 feet to follow the contours and to meet the grading policy, with a maximum fill of 3 feet. Basement The applicant has included a 1,883 square foot basement with the residence which would not count towards the floor or development area. The basement is designed to be under natural grade except at the west side, where it is up to 21/2 feet above natural grade. The applicant proposes to backfill along this section to ensure that no portion of the basement wall would be exposed. The exterior stairwell from the basement appears to be larger than the minimum building code requirements, therefore staff has included a condition that the plans be revised to reduce the size of the landing at the exit of the basement(see condition#1). Trees The driveway is to be located in the vicinity of a 12 inch oak tree. The driveway at this area is on grade, therefore the tree would not be disturbed during construction. Condition #6 requires that the dripline of the oak tree be fenced prior to construction to insure that the tree will not be negatively impacted. Modification of the conditions of approval The applicant is requesting a modification to the conditions of the tentative map for the subdivision, specifically requesting an increase in the allowable development area for the lot. The conditions currently limit the development area to 9,340 square feet, although the development area per the Town's ordinances would be 47,345 square feet. The difference in the MDA numbers is due to the area of the lot (about 3.1 acres) which is in open space and conservation easements, which was deducted from the Matadero Creek calculation. The applicant requests 3,643 square feet more area than is allowed per the conditions. The architectural review board for Matadero Creek has reviewed the plans Planning Commission January 14, 1998 Lands of Rutner Page 5 and has indicated support of the whole project, inclusive of modifying the condition of the tentative map for the increased development area allowed for the lot. The maximum allowable building coverage is not included as a conditionof approval of the subdivision, although it is defined as 44% of the development area within the CC&Rs. The increase in the allowable development area would consequently increase the allowable building coverage from 4110 to 5,713 square feet. The proposed building coverage is 5,140 square feet, well within the allowable coverage if the development area is increased for the lot. In order to approve a map amendment, the Commission must make findings similar to those made for the subdivision (see Attachment 2 for findings). The Architectural Committee and staff concur that Lot 7 is considerably more constrained by easements than other properties in the subdivision, and that the design has not infringed on the areas of the easement or their intent to maintain open space on the site. Modifications to the allowable limitations on other lots in the subdivision have been approved by he City Council in the past. Matadero Creek Architectural Review Board The Matadero Creek Architectural Review Board has reviewed the plans and the proposed modifications to the conditions of approval of the tentative map. The Board has indicated their support with individual members signing plans and/or letters. The Board indicates that the modifications are supported only because the residence has been designed in such a way as to minimize impact on the neighbors. Other Staff and Committee Recommendations The proposed development has been reviewed by the Town Geotechnical Consultant and there are some minor concerns regarding the construction design of the residence. The construction drawings are required to be reviewed by the applicant's geotechnical consultant with a letter of compliance for review by the Town's Geotechnical Consultant prior to issuance of building permits to assure that the concerns are mitigated. The changes to the proposed construction would not alter the location and height of the proposed residence. Additional information has been forwarded to the Town's Consultant for review. The Pathways Committee has requested that the IIb pathway along Matadero Creek Lane be restored, and condition#22 requires such restoration prior to final building inspection. The Environmental Design Committee notes that the residence will be highly visible from across the valley and that the color should match the Town's colorboard, as required in Condition#4. Condition#2 emphasizes the need to plant screening along the west of the development to decrease visibility from across Page Mill Road and Matadero Creek Lane. In addition, the Committee emphasizes that mowing in the open space and conservation easements is preferable to discing, as discing encourages the growth of star thistle. The Santa Clara County Fire Department requires that the applicant install fire sprinklers to the residenceto meet the required fire flow duration requirements. In addition, the driveway must meet access and turnaround requirements for emergency vehicles, as indicated on the plans. The applicant must also provide one private fire hydrant on the site,with the location approved by the Fire Department. Planning Commission January 14, 1998 Lands of Rutner ' Page 6 Staff is available to answer any questions that the Commission or community may have. ATTACHMENTS: 1.

The residence specifically designed for Lot #7 is designed under the limitations given for elevation of the structures and all Town codes and has been designed with minimal impact to neighbors, therefore the development area can be increased. 2. The modification does not impose any additional burden on the present fee owners of the properties. There is not any effect on the sizes of the lots, the locations or extents of the streets and roads, or the Town's Maximum Floor Areas and Maximum Development Areas allowed for the properties. 3. The modification does not alter any right, title, or interest in the real property reflected on the recorded map. While the modification includes the increase of development area within the subdivision conditions, the proposed development area would meet Code requirements. 4. The modification is consistent with the Town's General Plan in that the General Plan does not have specific restrictions regarding the development area for lots. 5. The area affected by the change in the development area limitation is minimal and will not impact neighboring properties. 6. The proposed modification will not cause public health problems, or environmental damage, including injury to fish or wildlife and their habitats since the properties will still be required to meet the provisions of the Town's Code which address these issues. 7. The proposed modification will not adversely affect any existing easements acquired by the public at large, for access through or use of, the affected properties. • TOWN OF LOS ALTOS I-i.II.,I..S PLANNING DEPARTMEN'1 26379 Fremont Road • Los Altos Ilills, California 94022 • (415)941-7222 • FAX (415) 941.3160 WORKSHEET #2 EXISTING AND PROPOSED DEVELOPMENT AREA AND FLOOR AREA • TURN IN WITH YOUR APPLICATION • PROPERTYTSWN}.;R'S NAME - - - - -- - -- _ IskOf'k t'I'Y AL)L)RISS` -- - , -- ---- -- - �AL('i7I,A'rEIs13Y ..-_ �_Q�` ( cO 1.

In addition,we have reviewed pertinent technical documents from our office files (TMI-81 Matadero Creek Subdivision) and completed a recent site inspection. DISCUSSION The applicant proposes to construct a residence with basement, cabana, and swimming pool in the southern half of the subject property. In our previous review report (dated August 4, 1997), we evaluated a site development plan that included 1,580 cubic yards of proposed fill placement. Proposed site grading currently includes 3,560 cubic yards of cut and 335 cubic yards of fill. CONCLUSIONS AND RECOMMENDED ACTION Proposed site development is constrained by possibly thick, potentially expansive soils, strong to violent anticipated seismic ground shaking and possible seasonal shallow groundwater conditions. We have discussed the revised site development plan with the Project Geotechnical Consultant and are in general concurrence with the consultant that the proposed site layout and development plan is geotechnically feasible. However, the final design of drainage discharge systems should reflect consideration of the depth and engineering properties of site soils (to be determined during the upcoming site specific soil and foundation investigation). In general, we favor conveying concentrated site drainage directly to existing storm drain Northern California Office Southern California Office 330 Village Lane 5245 Avenida Encinas • Suite A Los Gatos,CA 95030-7218 Carlsbad,CA 92008-4374 (408)354-5542 • Fax(408)354-1852 (760)931-2700 • Fax(760)931-1020 e-mail:losg@csageo.com e-mail:carl@csageo.com Debbie Pollart September 9, 1997 Page 2 L3357A systems rather than dispersing water into shallow trenches as currently depicted. We note that some portions of the drainage outfall trenches are located relatively close to the existing cut slope above Matadero Creek Lane resulting in the potential for surfacing of seepage or slope instability. With the above understanding, we recommend geotechnical approval of the proposed site development plan. The Project Geotechnical Consultant should address issues of appropriate site drainage design and develop recommended project design parameters during the upcoming geotechnical investigation. The resulting report should be reviewed and approved by the Town Geotechnical Consultant prior to preparation of detailed project construction plans, or submittal for building permits. This review has been performed to provide technical advice to assist the Town in its discretionary permit decisions. Our services have been limited to review of the documents previously identified, and a visual review of the property.

Mr. Curtis Williams, Planning Director Re: Lot 7 Matadero Creek Subdivision,Development Area Dear Curtis; Peryour discussions with Mr.Larry Bridgman on 11-26-97,we are writing to request that you modify the condition of approval#7B for the Matadero Creek Subdivision to allow a development area of 12,973 square feet for Lot 7. As you know, we have met with the Matadero Creek Architectural Committee on this subject and they approve of this requested modification. We believe that we now have a complete site development application package and would like to request that we be placed on the Planning Commission hearing agenda on January 14, 1998. In the mean time, if you have any questions, or need additional information,please call Pong Ng at(408)985-6048 and we will respond immediately. Thanks for your help•in this matter.

For the last nine months,we have worked very hard to pursue this dream. I am happy to say that we are close,but we need your help to enhance our chances of an approval by the Town. From the beginning, we have worked closely with the Matadero Creek Architectural Committee. Following their advice,we spent nine months relocating our driveway approech from the south side of the lot to the west side to improve auto aafety. When we started our project,we worked closely with the Town's planning staffto make sure we meet all the design requirements and their instructions. Alter designing the project, we submitted the plans for the committee's review, Their ia- 16-97 letter to us ended with this parageph: "Finally,the Committee realizes and appreciates the amount of time and energy being expended by all parties related to Lot 7, and hopes all parties cart come to an objective, fair, and friendly agreement among neighbors.' We have since met with the committee representatives on 11-11-97,and together again with the Town's Planning Department on 11-12-97. The committee and the Town both agreed that we can proceed with our planning application with the current design, At the same time,we will seek the neighbors' full support for our project as .designed. • The issues at hand are complex and revolve around interpretations of floor areas according to the Metadero Creek CC&R and the Town's Ordinance 305. One fact that is not disputed is that we have a nice design that the architectural committee and the Town both appreciate. The house it well hidden,low profile, and fulfills all the criteria the architectural committee has prescribed. Attachment 1 describes all the considerations put into the design and the reasons why the architectural committee finds the design desirable. 11/18/1397 17:22 941-1635 MCMILLS SRIDLNP'N ri-rut �JG As*Ducted to before,the issues at hand have to do with how floor areas are counted and how the requirements of the Matadero Creek CC&R and the Town's Ordinance 335 are met. Attachment 2 details the accounting of the proposed floor and development areas. While we believe we have met all the requirements, different interpretations on how areas are counted can lead to different conclusions. During the 11-12-97 meeting between ourselves, the Town and the architectural committee, the solution agreed to by all parties is that we would seek a lot-specific resolution that will allow us to build the house as designed on lot 7,using the proposed floor areas regardless of how they are counted. This is not a novel approach for the Matadero Creek Subdivision. In fact,various lots have had their approved floor and development areas modified by similar resolutions. In addition,a lot.specific resolution does not change the CC&R and the interpretations oi'the rules for other lots in the subdivision. The architectural committee members present at the meeting approved of the resolution. If the rest of the neighbors approve our request,the Town's staff can officially support our project as currently designed.. While the following point is not discussed during our meeting, to farther demonstrate our sincerity that this is the only resolution we will ever seek,we wilt record a deed restriction on our lot stating that the approved floor and development areas are all that is specifically allowed for lot 7. Neither we, or any figure owners,can expand on these approved numbers, We sincerely hope that you can help us secure OUT planning approval by signing your endorsement on this letter, We will be pleased to meet with you in person to discuss our project and show you the home that you will be approving. Thanks again and we hope to be pert of the Matadero Creek neighborhood soon. Sincerely, Robert it Peggy Kutner Approved, Date • 11/19/1597 17:22 541-1035 MMCMILLS 13R1 'Gf N 1-,AGE �]3 ATTACHMENT 1 We have a large,young seemly,and have always wanted a large lot which will give our children a lot of land to play.We need a high bedroom count for our five children, and that c&le kr a larger house. Lot 7 is more than 4.4 acres,and is perfect for our situation. We feel that if there is a lot in Matadero Creek suited for a larger home, tot 7 would be that lot. Lot 7 is unique in that it is surround by streets on three sides. Lot 6 is contiguous to our north,but there is some 250 feet of easement open space between us. Where our house is proposed,we are at least 300 feet away from any of our neighbor's house. In addition, our house is located on the lower portion of the lot, and as evidenced by the story poles that are in place,the house is relatively hidden tom most surrounding homes. We realize that the original vision of the Matadero Creek subdivision was to maximize open space between neighbors and locate the homes where the natural fall of the land can mitigate their visibility. We believe we have designed towards those goals. The letter from the Matadero Creek Architectural Committee dated 10-16-97 contains the following comments on the good design elements of our proposed project: • The building circle to be located where we have proposed. • The sight lines to be based on the story poles currer_tly in place. • No grading beyond ten feet from house walls. • The proposed hone is not visible from the home on lot 6. • Use planthrg to mitigate the driveway,use turf block driveway of dark color, • Rouse color scheme not to have beige with red or pink tones, use dark color roof of Synthetic slate. • Driveway access to be away from home on lot 18. • All dirt removed from excavation to be relocated on the property no higher than the 556 toot contour. We are in Lull cormpiiance with the above comments form the committee. The design objective is to bury the eastern and southern sides of the garages and portions of the secondary stair into the hillside to create the appearance of a ore-story structure from Matadero Creek Lane. The remaining two-story facade Is oriented towards the east end Page Mill Road,however, as the cars come up the bill, the natural slope shields the BM story from view. This also allows us to sink the house into the hill and lower the avaxll height and bulk of the visible structure. In fact,the maximum roof elevation of our proposed home is elevation 544'4',whereas Matadero Creek CC&R allows us a invtlintum roof elevation of 555'. We are more than 10 feet below the maximum allowed. The neighbors across Page Mill Road to the east have reviewed our plans and viewed the story pole locations,and are pleased with our design and stricture placement as we preserved their views of the ridge and the bay beyond. 11/19/1997 17:22 941-1035 MCMILLS BRIDGMAN FACIE 04 ATTACHMENT 2 RUINER RESIDENCE Maximum Building Area Compliance Ordinance 305 Compliance Maximum roar Area(MPA) : Allowable 2121;206 square feet.

SUMMARY and RESOLUTION As you can see,the proposed project floor and development areas are far below the Ordinance 305 allowable areas which is the standard all other projects in the Town must meet. Where we are over the limit is in the development area when we abide by the interpretations of the Matadero Creek Architectural Committee. In order to facilitate the planning approval of our project, the Town's Planning Staff, the Matadero Creek Architectural Committee and ourselves agree that we would seek approval, from the Town and the Metadero Creek Subdivision residences by resolution, to allow us to build a home en lot 7 with the following areas . First floor living area-3,682 square feet. Second Floor Living Area=3,400 square feet. Second floor balcony=60 square feet Cabana erne.398 square feet. Geroge and shop area= 1,023 square feet. Pool,decks,walk,driveway, parking=4,048 square feet We feel that these numbers are reasonable given the size of the lot,the need of our family, and the design of the home. Since we meet ail the area requirements of Ordinance 305, we are not seeking a variance. The Matadero Creek Architectural Committee approves of our request. The Town's staff has indicated if the residences of the Matadera Creek Subdivision endorse this resolution, they would support our application for approval of a Site development permit. These building and development areas are specific to lot 7 only. Furthermore,we agree to record a deed restriction on our property such that in the future, neither ourselves,or any future owners, can expand on these approved numbers. We sincerely hope that you will support our project es proposed, L4-44C-d kid/4- 2-4-a AMA) . ,
