BACKGROUND The applicant is requesting approval of a Site Development Permit to install a 840 sq. ft. swimming pool and spa and landscape screening on the property. The subject property is located on the north side of La Lanne Court where a new residence is currently under construction. Surrounding uses include single-family residences on adjacent properties to the east, north and west, and across La Lanne Court to the south. On August 8, 2002, the Planning Commission approved a Site Development Permit for a 5,238 sq. ft. two-story residence with a 3,648 sq. ft. basement on the property (Lands of Benzacar, SDP# 19-01-ZP-SD-GD). During the Planning Commission hearing in 2002, several neighbors expressed concerns about potential drainage problems as well as visual and privacy impacts of the new home. (Attachment 4) As required by the Condition#2 of the new residence approval, the applicant submitted landscape and hardscape improvement plans for site development review on January 24, 2005. CODE REQUIREMENTS Per Section 10-2.301.b of the Site Development Ordinance, this application has been forwarded to the Planning Commission for review and approval. The Zoning and Site Development sections of the Municipal Code are used to evaluate the proposed pool and spa including development area limitations, grading, drainage, height, setbacks, and visibility. Section 10-2.802 of the Site Development ordinance is also used to evaluate landscape plans to address erosion, noise, visual effects, maintenance, tree preservation, views and amount required to adequately screen the new construction. r 1 Staff Report to the Planning Commission Lands of Kariat 25721 La Lanne Court April 6,2006 Page 2 of 7 DISCUSSION Site Data: Net Lot Area: 1.008 acre Average Slope: 14.7% Lot Unit Factor: 0.91 Development and Floor Area: Area (sq.ft.) Maximum Existing Proposed Increase Remaining Development Area 12,046 10,546 11,997 1,451 49 Floor Area 5,246 5,238 0 0 8 Trees &Landscaping The property is heavily vegetated around the perimeter by various trees and shrubs including mature pine trees along the north (rear) property line, an oleander hedge along the west (side) property line, and a fair number of oak and pine trees along the east (side) property line. To address neighbors concerns about view and privacy impacts, the applicant is proposing to install twenty-one (21) 15 gallon Sequoia sempervirons (redwood) trees on the east side of the house to provide screening for the adjacent neighbor at 25691 La Lanne Court: In addition, eleven (11) 24" box Oleaceae (olive) trees will be planted in several clusters along the west property line to help screen the roof line of the new home from the adjacent neighbor at 14320 Miranda Way. During the review of the project back in 2002, the Planning Commission had indicated that a 14" tree located near the driveway should be preserved or relocated if possible because it will help screen the house from the street. Unfortunately, the applicant was unable to preserve the subject tree and it was removed during construction in April 2005. To mitigate the loss of the 14" tree, staff is recommending the installation of two (2) 60" box oaks along the front of the property. (Condition#3) In total, the applicant is proposing to install thirty-three (33) new trees on the property to supplement the existing landscape screening on the property. The new trees are required to be installed prior to final inspection of the new residence.

AYES: Chairman Vitu, Commissioners Wong, Clow,Kerns &Cottrell NOES: None This approval is subject to a 22 day appeal period. 3.3 LANDS OF BENZACAR, 25721 La Lanne Court (19-01-ZP-SD-GD); A request for a Site Development Permit for a new residence (continued from the July 23, 2002 Fast Track hearing). Commissioner Wong stepped down from the hearing due to the proximity of the application site to his residence. Staff (Debbie Pedro) introduced this item noting it was scheduled for a Fast Track hearing but there was some opposition from neighbors and it was scheduled for a Planning Commission hearing. Since that time, two more letters from neighbors (a petition and letter from Mr. and Mrs.Fatemi) have been received. OPENED PUBLIC HEARING Roger Kohler, 721 Colorado Avenue, Palo Alto, project architect, stated he has been working with staff for two years on this'project. He provided a cross section through the site and through the neighboring site on Miranda Way. This two story house has been sunken down into the grade. He referred to Attachment 4 of the staff report stating there will be a little roof showing but the applicant plans on landscaping aping the site and in a short while this view of the roof will disappear. They tried to lower the house and reduce some of the windows in the rear to comply with the neighbor's request. Will Clark, Lee Sung Engineering, project engineer, discussed drainage concerns stated they have worked hard to minimize the impact on the neighbors with on-site retention to detain some of the water on site and located the energy dissipater towards the rear of the property where it would have the least amount of impact. They are willing to work with staff regarding drainage issues. Sohrab Kianian, 14320 Miranda Road, bought their house two months ago. The realtor told them plans had been submitted for 25721 La Lanne Court for a one story home and that it would never block their views. The realtor also told them that during rainy season she had noticed that the neighboring site was like a marsh and drainage was a problem on that site. His main concern was if drainage effects neighbors, it would effect their Planning Commission Minutes Approved 9/12/02 August 8, 2002 Page 5 of 11 property value. He further discussed view concerns which involved a huge red roofline. Currently, they have an unobstructed view. Homi Fatemi, 25691 La Lanne Court, discussed concerns regarding privacy and drainage. He felt the proposed plan had done a good job of capturing the surface water. He suggested a trench depth be a minimum of 7 feet. He was concerned with the runoff from the driveway which will be directed towards La Lanne Court and end up on his driveway. He suggested capturing the driveway water via a catch basin and then connecting this basin to the dissipater in the back of the property. He was also concerned the future landscaping will add to the drainage issues. He felt this added water will put pressure on the existing retaining wall on his property and may cause it to collapse as the excess surface and subsurface water can potentially accumulate under his crawl space and cause foundation damage. His final concern was the roof height of the new construction. The height and windows facing his property will interfere with their privacy. He asked that the height be lowered. Mildred Gallo, 25720 La Lanne Court, discussed a previous situation she encountered on her property regarding drainage. She did not want the Fatemi's to experience the same situation. Sam Benzacar, applicant, felt there were two concerns: drainage and views. He will be happy to accommodate the neighbors regarding drainage issues. Regarding views, he did not feel this was an issue as you are bound to see rooflines. He has done everything to conform to Town policy and codes. He felt the previously approved plan was not good for the neighbors. His project will have minimal impact on views and heavy landscaping would impact their view. Sandy Humphries, Environmental Design Committee, suggested plantings, at maturity, be no higher than the roof. Susan Ezzati, 14320 Miranda Road, was concerned with the massive roof. She felt it would be better to lower the height of the structure and change the color of the roof to blend into the neighborhood. She would prefer looking out onto greenery. Sohrab Kianian, 14320 Miranda Road, was concerned with the water runoff associated with a heavy landscape plan which will create even more drainage concerns. Fai Fatami, 25691 La Lanne Court, reviewed her addition/remodel application completed three years ago noting that they considered the effects on their neighbors. She thought it was unfair that they would be having a two story structure looking down onto their property. She asked that no more trees be removed and that the windows on her side of the property be reduced. Dot Schreiner, 14301 Saddle Mountain Road, discussed the conditions of approval, recommending adding the reflectivity value of 40% or less for this site as a condition. Planning Commission Minutes Approved 9/12/02 August 8, 2002 Page 6 of 11 Sandy Humphries, Environmental Design Committee, need to consider putting in partial drip irrigation system to help with water mitigation. Mr. Benzacar in answer to comments, he commented that the roof will not be red but a Mission style with a variety of colors. Regarding trees, he loves trees as they add to the value of the site. He did not feel it was a realistic request to lower the house. Will Clark, Lee Sung Engineering, project engineer, discussed controlling the drainage and their willingness to work with the neighbors. Commissioner Clow asked about the 14" tree (20d) next to the lower driveway marked to be removed, asking if it could be saved by moving the driveway. Mr. Benzacar thought this was possible. Commissioner Kerns asked if the house could be moved slightly back to save a 14" tree close to the light well. Mr. Benzacar did not feel this was possible (house would be higher) but suggested transplanting the tree. He noted any change will impact something. CLOSED PUBLIC HEARING Commissioner Cottrell noted the major drainage issues and reviewed all proposed drainage measures shown on the plans and the engineer agreeing to increase the depth of the trench, if necessary. He thought they should review the neighbor's retaining wall. He felt the site could be sufficiently landscaped to hide the roof and suggested a condition of approval regarding the roof reflectivity vale of 40% or less. Commissioner Clow agreed. He was not in favor of asking the application to lower the house. Having landscaping to mitigate the visual impact is a great idea. He reiterated his request to maintain the 14" tree in the front to hide the structure. He could make findings that this is a visible structure and should impose the reflectivity value for the roofing material. Commissioner Kerns liked the architecture of the house and had no problem with the height. He would like to see them work with the neighbors regarding landscaping to mitigate the house. He also felt adding some additional drainage grates across the entrance of the driveway would be helpful. He would also like to save the 14" tree in the front and the other 14" tree by the light well. He did not feel this was a highly visible house. Chairman Vitu agreed with previous comments. The applicant has done an excellent job with siting the house. The roof can be mitigated with landscaping and the applicant can work with the neighbors regarding drainage issues, in particular, the retaining wall and the runoff from the driveway. She agreed with adding a condition regarding roof reflectivity value. MOTION SECONDED, AMENDED AND PASSED: Motion by Commissioner Clow and seconded by Commissioner Cottrell to approve the request for a Site Development Permit for a new residence, Lands of Benzacar, 25721 La Lanne Court, with the following additions and changes to the conditions of approval: (1) add to #2, Trees shall also be planted along the western property line to screen the roof from the adjacent property at 14320 Miranda Way. The existing 14" tree located along the south property Planning Commission Minutes Approved 9/12/02 August 8, 2002 Page 7 of 11 line shall not be removed. The applicant shall make a reasonable attempt to preserve or relocate the 14" tree northeast of the main entrance. (2) The roof material shall have a light reflectivity value of 40 or less and made of a non-reflective material. and (3) The applicant shall revise the drainage plans to address runoff from the driveway and drainage impacts to the neighbor's retaining wall at 25691 La Lanne Court. The trench energy dissipaters located in the rear of the property shall have a depth of 7 feet. AYES: Chairman Vitu, Commissioners Kerns, Clow &Cottrell NOES: None ABSTAIN: Commissioner Wong (stepped down) This approval is subject to a 22 day appeal period. 3.4 ORDINANCE AMENDMENTS TO THE TOWN'S ZONING CODE WITH REGARD TO DRIVEWAYS (SECTION 10-2.1102). The Planning Director introduced this item by noting the ordinance is in line with what the Planning Commission had forwarded to the City Council. Staff is recommending one change on driveway widths: "(g) Driveways shall meet all standards for width, vertical clearance, grade, surface, weight, turning radius, turnouts, and turnabouts as established by the Santa Clara County Fire Department except that driveway width shall not exceed 12 feet when located in required setbacks." The ordinance amendment would set Town driveway design standards to be generally consistent with Fire Department standards with the exception of driveway width in setbacks. The Fire Department indicates that 14-foot wide driveways are preferred with no exceptions. Staff recommends that driveway width be maintained at 12-feet in width for at least that portion located in the setbacks. This is to minimize the appearance of asphalt paving in the setbacks and to provide more space for landscaping. Discussion ensued. OPENED PUBLIC HEARING Dot Schreiner, 14301 Saddle Mountain Drive, felt they should take the Fire Department recommendations. She liked the recommendation for the Town to have some leeway. She was concerned with the statement that in the setbacks they can only have a width of 12 feet. If she was an applicant, that is what she would go for which would give them more development area to use elsewhere. She was also concerned with the statement in # (h) asking what happened to the 10 foot grading restriction. Sandy Humphries, Environmental Design Committee, asked if the intent is to reduce the amount of paved surfaces, they should eliminate circular driveways. i- M91.,VIRONMENTAL DESIGN COM JCTEE PA , A 19NNT LANDSCAPE/HARDSCAPE ENa-E--1VA t,,O T FEB Z 3 2005 Applicant's Name: A-P,t Irt— AUG 18 ;tfln; TOWN OF LOS ALTOS Hi--LLS L-(� 1-44i'VaLF n.-- ea,oyq'i Address: Reviewed by: l Date- CQ Mitigation needed: Visibility from off site: from distance (directions) -by frorvf', A, -par neighbors -(dirtctions) (include need for screening T Noise: frompiimp/pool _, air conditioner sport court Lights: from fixtures automobile headlights Erosion control wen/solid, Fence materials: color APR Other: Manting Plan Evaluation: (Circle required trees and shrubs on plan) Are species appropriate: Deciduous?
