.03 U-2006-13 Larry Guy CITY OF CUPERTINO 10300 Torre Avenue, Cupertino, California 95014 DEPARTMENT OF COMMUNITY DEVELOPMENT REPORT FORM Application: U-2006-13, ASA-2006-22, TM-2007-02, Z-2006-05 Agenda Date: June 26, 2007 Applicant: Larry Guy Owner: Douglas Russum Location: 10855 N. Stelling Road APPLICATION SUMMARY: Use Permit to construct 20 single-family residential units (10 detached and 10 attached) on a 1.1-acre site (northwest corner of N. Stelling and 1-280). Architectural and Site approval to construct 10 small lot single-family residential homes and 10 attached town homes. Tentative Map to subdivide a 1.1-acre parcel into20 parcels and one common parcel. Re-zoning of a 1. I-acre parcel from BQ (Quasi-Public) to P-Res (Planned Residential) RECOMMENDATION: Staff recommends that the Planning Commission: 1. Recommend approval of U-2006-13, ASA-2006-22, TM-2007-02 and Z-2006-05 subject to the model resolutions. Project Data: General Plan Designation: Zoning Designation: Site Area: Density: High Density Residential (20-35 d.u./ acre) BQ (Quasi-Public) 48,044 square feet (1.1-acre) 16.1 dwelling unit per acre Environmental Assessment: Categorically Exempt BACKGROUND: The applicant, Larry Guy, is requesting approval to construct 20 residential homes (10 small lot single-family and 10 attached town homes) on an existing parcel located at 10855 N. Stelling Road at the northwest corner of N. Stelling Road and 1-280. The project site is'approximately 1.1 acres (net) and consists of one single family home, one large detached building and several accessory structures. The project proposes the following 'project details: j,../ Applications: U-2006-13, ASA-2Q06-22 TM-2007~02, Z-2006-05 Las Palmas June 26, 2007 Page 2 20 (10 detached and 10 attached) 16.1 35 to 38 Covered: 40 Open: 14 Street: 2 Total: 56 Since the proposed zoning is Planned Residential and the project site is not located in any specific plan areas, there are no specific maximum height and minimum setback requirements. ~ I -.... .~ ,... ... ,.

The new zoning proposed for the project site is P(Res)- Planned Development Residential to allow the new 20 unit residential project. General Plan Density The proposed rezoning is compatible with the General Plan (high density residential) land use designation. The specified density range for this parcel is between 20 - 35 d.u.jacre and the project proposes 16 d.u.jacre, which is under the minimum range. The General Plan residential density indicates the desired development intensity for different areas of the City. However, the actual gross density may vary if the proposed project reflects the general development character of the neighboring properties (GP Policy 2-28). The project can not reasonably match the development character of the neighboring properties as it is surrounded by a church to the north & west, 1-280 to the south, and Villa Serra apartment project to the east, separated by Stelling Road. In addition, due to physical constraints of the project site (Le., the size of the property and the locations of existing protected trees, proximity to 1-280, lack of area for parking spaces), the proposed lower density allows for a better site design and project. More units may compromise the livability and desirability of the project. Therefore, staff recommends that the Planning Commission allow the requested project density. Historic Preservation On May 5,1997, the City Council appointed five Cupertino residents to the Historic Research Committee charged with researching 32 potential historic sites. The report was completed but at the time the City Council did not direct any further actions and preservation ordinance was developed. Therefore, the 1997 historic report generated by the Historic Research Committee is considered informational only. The proposed project site (a.k.a. Tracy House - see exhibit A) is listed on the 1997 historic report and was ranked 16 out of 32 in terms of overall historic value. Even so, the site was recommended as historic mainly because of the desire to honor Enoch Perrish, an early designer and builder (late 1800s to earlier 1900s) who may have been connected in building and moving the existing residence to the project site. According to Sharon Hoyt, a historic researcher with the Cupertino Historic Society, the existing Tracy house was probably built in the 1890s. It was originally located on Lawrence Road and later moved to its current location on N. Stelling Road in 1937. Even though the existing residence was built by a reputable builder, the home does not take on any coherent or significant architectural styles. It has a blend of Victorian style, Ionian style, Tudor style and Craftsman style. In addition, a portion of the original house was moved to its current location. The home is in failing condition and both the applicant's architect and the City's consulting architect have confirmed that there is not any significant architectural value that warrants its preservation or relocation. 3 ~'3 Applications: U-2006-13, ASA-2006-22 TM-2007-02, Z-2006-0S Las Palmas J nne 26, 2007 Page 4 .-- I --------r I I _~.4 ~".,,'_'f. ______ M' , ' ". ," t . ------ . f - - - - -----:;:;.::' ., 3'4 Applications: V-2006-13, ASA-2006-22 TM-2007-02, Z-2006-05 Las Palmas, June 26,'2007 Page 5 The proposed project attempts to mimic s,ome of the architectural style of the existing residence by introducing different architectural treatments (Victoria~, Ionian, Tudor and craftsman) 9n each of the W'lits.

A memorial plaque shall be erected in the proposed common plaza area' where the history the existing residence would be available for public recognitiol'l. 2. The applicant shall use elements from the existing home to COl'lstruct a trellis or gazebo structure at the common plaza area. 3. The applicant is required to work with a professional building salvage company to salvage and reuse as much of the existing home as possible. Tentative Map The applicant proposes subdividing the existing parcel into 21 parcels (~itl'l one common parcel that facilitates the driveways and common open space. Technical Issues: Site and Architecture Currently the site is accessed by one driveway off of N. Stelling Road located close to the northeast corner of the site that serves the existing residential home. The entry driveway to the proposed project will still be from N. Stelling Road but will be located close to the middle of the project frontage in order to minimize any potential vehicular conflicts with the adjacent church driveway located further north. There is little landscaping opportunity throughout the site except along the perimeter of the project site. An approximately 2,500 sq. ft. public plaza and outdoor op~n space is proposed at 5 ;"5 Applications: U-2006-13, ASA-2006-22 TM-2007-02, Z-2006-05 Las Palmas June 26, 2007 Page 6 the end of the entry drive along the rear (westerly) property line creating a focal point for the project. Permeable decorative pavers are used throughout the entire interior driveway system to enhance onsite permeability and aesthetic qualities. The proposed preliminary architecture was reviewed by the City Consulting Architect and the applicant has incorporated all of changes and enhancements recommended by the City Architect. Staff recommends that the final color and building materials (including but not limited to pedestrian/building/parking lot lightings, patio railings, trellis materials, outdoor furniture, siding materials, common gateway features or any other similar exterior decorative features) be of high quality and shall be reviewed and approved by the Design Review Committee prior to issuance of building permits. In addition, staff recommends the following enhancements to the project: . Additional screen trees should be located along the southerly boundary of the project to the maximum extent possible to mitigate any potential visual and noise impacts from 1-280. . Pedestrian connection/ access should be provided along the northerly property line between the project site and the adjacent church property. . The applicant shall work with staff to lower the front entry porches and entry stair of unit type 1 so that the entry feature and the front porches are at a pedestrian level. . The common entry points to the court yard areas shall be decorated with trellises and lighting features or with similar architectural elements. In addition, the common plaza area shall be decorated with pedestrian scale lighting and benches. . Bio-swales should be introduced wherever possible along the southerly property boundary. . The curb alignment along the project frontage should be adjusted to allow for a new detached sidewalk with additional street trees planted in front of the project. . Plant vines on and through the sound wall to discourage graffiti. 6 3~(p Applications: U-2006-13, ASA-2006-22 TM-2007-02, 2-2006-05 Las Palmas June 26, 2007 Page 7 ;).

Page 8 Parking The City Municipal Code requires 2 enclosed spaces and .8 open spaces per each small lot single family unit or town homes proposed. Based on this ratio, the project is required to provide 56 spaces (40 enclosed and 16 open). Two of the open spaces are located on N. Stelling Road along the property's frontage. In several previous projects, the City has allowed off-site street parking to be used by the project to satisfy parking requirements. In those circumstances, either the specific plan of the area prescribes for such parking credit or when there is an identified public benefit associated with the application. Staff recommends the following public benefits to justify the on-street parking requested: .:. Realignment of the existing curb (straightening and extend northerly and terminating prior to the adjacent church driveway) along the project frontage in order to facilitate a new detached park strip thereby enhancing the pedestrian experience with new street trees and landscaping area. .:. Contribution of $50,000 for enhancements to the pedestrian walkway along the west side of the N. Stelling Road bridge that crosses over Interstate 280 located south of the project site. The city shall use the money to add pedestrian scaled lighting, paving materials, railings and/ or repainting of the pedestrian facilities of the west side of the bridge. A similar requirement was recommended on the Villa Serra development on the east side of Stelling Rd. Traffic and Circulation A traffic and circulation analysis was prepared by Fehr & Peers dated April 24, 2007. It should be noted that at the time of the traffic analysis, the project consisted of 22 units and has since then been reduced to 20 units. The number of trips generated by the proposed project was estimated by applying trip rates from Trip Generation (Institute of Transportation Engineers, 7th Edition) to the size of the project. The proposed project is estimated to generate 25 AM peak-hour trips (6 inbound/19 outbound) and 27 PM peak-hour trips (17 inbound/l0 outbound). Two intersections were also reviewed for potential impacts (Homestead/Stelling & Stevens Creek/Stelling), and based on the small number of trips generated by the proposed project, operations at these two nearby intersections are not expected to substantially degrade. Noise A noise analysis was prepared by Environmental Consulting Services on March 8, 2007. The noise report presents results from the on-site monitoring, projection of future noise levels and a description of architectural details relevant to noise protection performance (see exhibit D). Based on the site noise measurements, anticipated future traffic volumes, and noise modeling, the worst case design noise level for the project residential unit would be 78 dBA (with the installation of a noise barrier on the south property line). To meet the City of Cupertino residential noise criteria, the following design measures must be met: 8 '3"e Applications: U-2006-13, ASA-2006-22 TM-2007-02, Z-2006-05 Las Palmas June 26, 2007 Page 9 .:. Windows: windows in units adjacent to and with a view of 1-280 shall have STC (Sound Transmission Class) of at least 33 dB. Special acoustical windows, with larger air spaces between panes, or with a thin plastic laminate layer between glass layers, can be obtained with STC ratings of 33-38 STC. A STC rating of 29- 30 would be acceptable for units located away from 1-280. High quality double- glazed thermal window, with two 1/8/1 lights separated by a 3/8/1 to 3,4/1 air space, and good weather seals if openable, have ratings of 27-30 STC. .:. Party Wall Assemblies: for minimizing noise transmitted between attached residential units, the party wall assembly should have several inches of air space, fiberglass insulation and minimal structural connections, and generally resilient channel (RC) attached to one side of the party wall, in order to meet the 50 STC requirement. In addition, any fire stop between units should not provide a strong structural connection. That is, they should be of light weight materiat such as sheet metal or fiberglass that cannot conduct low frequency sound and vibration between units. - .:. Exterior Doors: Entrance doors and sliding glass doors should meet an STC rating of at least 25-27 dB. .:. Ventilation: All units must have a ventilation system that provides a habitable interior environment with the windows closed, regardless of outside temperature. .:. An eight-foot sound wall shall be erected along the entire southerly and westerly property line. Affordable Housin~ Per the City's Below Market Rate (BMR) requirements, 15% of the new units are required to be allocated as BMR units. Based upon a total of 20 new residential units, the BMR requirement for the project is 3 units. Tree Removal A total of 16 trees have been documented by the City Consulting Arborist on the project site, three of which are defined by the City Ordinance as specimen trees (Trees #1, 2, 6- Co~st Live Oak). The City Arborist has also identified approximately 57 additional less significant trees (fruit bearing, nut bearing and other various types) on the site that are not protected by the Ordinance. The project proposes to remove 11 trees (#3,5,7-14 and 16) and relocate two (#4 and 6). Trees number 1 and 2 are required to be preserved. With the exception of trees #9 and #11 (dead poplar and pine structurally unsafe), all removed frees shall be replaced at a one-to-one ratio with minimum 36-inch box size trees, which results in nine new trees. In the event if trees #1, 2,6 are lost as result of the construction, each trees shall be replaced with two minimum 48-inch box size replacement trees. The final landscaping 9 ?;,q Applications: U-2006-13, ASA-2006-22 TM-2007-02, Z-2006-05 Las Palmas June 2?, 2007 Page 10 plan shall be reviewed and approved by the City prior to issuance of building permits. 111. addition, the City Consulting Arborist shall inspect all relevant tree protection measures prior to construction al1.d inspect prior to final occupancy to verify that all the preserved trees are in good standing. " Student Generation The school attendance areas in which the proposed project would be located are: Garden Gate Elementary, Lawson Middle School and Homestead High School. Plans were sent to the Fremont Union High School District and the Cupertll1.0 Union School district "for review and input. Only the Cupertino Union School District has confirmed that the project will not cause any significant impacts to the school system grades K thru 8th. The Fremont Union High School District has not responded with any comments. Staff attempted to contact the high school district representatives without success and assumes that the high school district has no comments on the project. Due to the size of the proposed project, it did not warrant a fiscal and enrollment impact analysis. However, based on the SGR (Student General Rate) from a previously approved similar town home project (Morley Brother, Pruneridge Avenue Development) in the City, the proposed project is expected to generate the following students: Las Palmas Development Total of Students Small lot single family and town homes Elementary (K-5) 0.25 " 5 SGR Middle (6-8) SGR 0.15 3 High School SGR 0.15 3 Total: 11 Students Environmental Review Staff det~rmll1.ed that tl1.e project is categorically exempted from CEQA (California Environmental Quality Act). A categorical exemptiOl1. is an exemption from CEQA for a class of projects that the Secretary of Resources determines generally will not have a significant effect on the surrounding environment. Based on Article 19, Section 15332, Class 32 in-fill development projects meeting the following criteria described below 'are exempted from CEQA: 1. The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designatiol1 and regulations; 2. The proposed development occurs within City limits on a project site of no more than five acres substantially surrounded by urban uses; 3. The project site has no value, as habitat for endangered, rare or threatened species; . 4. Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality; 10 3"'/0 Applications: U-2006-13, ASA-2006-22 TM-2007-02,2-2006-05 Las Palmas June 26, 2007 Page 11 5. The site can be adequately served by all required utilities and public services. The proposed residential project satisfies all of the above in-fill development criteria therefore exempt from any further environmental review. The Environmental Review Committee reviewed the project at its May 23,2007 meeting and concurs with the above findings of exemption. Green Buildin~ Desi~n Due to the recent interest on the desire of adopting green building designs, the City is in the initial process of determining the scope and direction of the City's green building standards. In the interim, staff suggests the following simple measures be applied to the project: . The project shall use tankless water heaters through out the project. Tankless water heaters are 20 to 30% more efficient than traditional water heaters. . The project shall use gas furnaces that have minimum efficiency ratings of 70%. Higher efficient furnaces on the market now can reach efficiency rating between 70% to 90%. . The applicant shall design the roofs of all residential units to be able to structurally facilitate future solar panel systems to account for the weight and wind loading factors. Final roof plans shall be reviewed and approved by the Building Official. . Lighter shades of roofing colors shall be used throughout the project in order to help reflect sunlight and to achieve cooler roof temperatures. All of the above measures and facts have been verified in consultation with Davis Energy Company in Davis, CA, a company appointed by the US Green Building Council as the chief LEED (Leadership in Energy and Environmental Design) certifier in California on green building projects.

Ryan Walbert Subject: Las Palmas Residential Development Focused Traffic Analysis SJ07-943 This memorandum presents the results of the focused traffic analysis conducted for the proposed 21-unit Las Palmas residential development, located at 10855 N. Stelling Road in Cupertino, California. The City of Cupertino requested that a larger project description, twenty-two (22) units, be evaluated. The purpose of the analysis is to identify the potential impacts of the proposed development on the surrounding transportation system in the project vicinity. Figure 1 shows a detailed site plan of the proposed project. Studv Locations The following intersections were selected for analyses in consultation with City staff: 1. Homestead Road and Stelling Road/Hollenback Avenue (City of Sunnyvale intersection) 2. Stevens Creek Boulevard/Stelling Road (CMP Intersection) The operations of the two study intersections were evaluated during the weekday AM and PM peak hour. The peak hour represents the highest one-hour volumes during the weekday . commute periods (7:00 - 9:00 am and 4:00 - 6:00 pm). Intersection turning movement counts were conducted at both study locations on January 25, 2007. The traffic counts are contained in Attachment A. Trio Generation Estimates The number of trips generated by the proposed 22-unit residential development was estimated by applying trip rates from Trip Generation (Institute of Transportation Engineers, 7th Edition) to the size of the project. Table 1 contains trip rates and estimates. The proposed project is estimated to generate 25 AM peak-hour trips (6 inbound/19 outbound) and 27 PM peak-hour trips (17 inboundl10 outbound). 160 West Santa Clara Street, Suite 675 San Jose, CA 95113 (408) 278-1700 Fax (408) 278-1717 www.fehrandpeers.com P"~~ Mr. Gary Chao April 24, 2007 Page 2 of 7 tp FEHR & PEERS ruilS10UATlOM CO.llSULTUTS TABLE 1 PROJECT TRIP GENERATION ESTIMATES Size AM Peak Hour PM Peak Hour land Use (Units) Rate In Out Total Rate In Out Total Single-Family Detached 22 . 1.13 6 19 25 1.25 17 10 27 Source: Trip Generation (Institute of Transportation Engineers', 7fto Edition). Levels of Service Methodoloav The operations of the intersections were evaluated using Level of Service (LOS) calculations. Level of Service is a qualitative description of an intersection's operation, ranging from LOS A, or free-flow conditions, to LOS F, or over-saturated conditions. The level of service methodology approved by the City of Cupertino and the VTA analyzes a signalized intersection's operation based on average control vehicular delay calculated using the method described in Chapter 16 of the 2000 Highway Capacity Manual (HCM) (Special Report 209, Transportation Research Board) with adjusted saturation flow rates to reflect conditions in Santa Clara County. Control delay includes initial deceleration delay, queue move-up time, stopped delay, and final acceleration delay. The average control delay for signalized intersections is calculated using TRAFFIX analysis software and is correlated to a LOS designation as shown in Table 2. The LOS standard (Le., minimum acceptable operations) for signalized intersections in the City of Cupertino is LOS 0 except at Stevens Creek Boulevard/De Anza Boulevard and De Anza Boulevard/Bollinger Road. These intersections must maintain LOS E+ operations (with no more than 60 seconds weighted average control delay). .3,a3 Mr. Gary Chao April 24, 2007 Page 3 of 7 fP FHIR & PEERS rU.SPOUAIIOI COMSULlurs TABLE 2 SIGNALIZED INTERSECTION LEVEL OF SERVICE DEFINITIONS USING AVERAGE CONTROL VEHICULAR DELAY Level of Average Control Delay per Service Description Vehicle (Seconds) A Operations with very low delay occurring with favorable :5 10.0 progression and/or short cycle lengths.

Source: vrA's CMP Traffic Level of Service Analysis Guidelines, June 2003, and Transportation Research Board, Highway Capacity Manual, 2000. Intersection levels of service calculations were conducted to evaluate intersection operations under Existing" Background, and Project Conditions. Background Conditions are defined as conditions prior to completion of the proposed development and serve as the basis to identify project impacts. Traffic volumes for Background Conditions comprise of existing volumes plus traffic generated by approved but not yet constructed developments in the area. A list of approved projects was obtained from the cities of Cupertino and Sunnyvale. The project traffic was added to Background volumes to represent Project Conditions.

Imoacts The results of the level of service calculations for Background Conditions were compared to the results for Project Conditions to identify significant impacts. City of Cuoertino Intersections A significant project impact to a Cupertino signalized intersection occurs if the addition of project results in: 1. Operations at a signalized intersection to deteriorate from LOS D or better under Background Conditions to LOS E or F under Project Conditions; or 2. Exacerbation of unacceptable operations (LOS E or F) at a signalized intersection by increasing the average critical delay by four (4) seconds or more and increasing the volume-to-capacity (V/C) ratio by 0.01 or more. With the addition of project traffic, the Homestead Road/Stelling Road intersection would continue to operate at LOS D (43.7 seconds of delay) during the AM peak hour and LOS E+ (57.3 seconds of delay) during the PM peak hour. The intersection would operate unacceptably during the PM peak hour; however, the project would not increase the average critical delay by more than four seconds or increase the v/c ratio by more than 0.01. Therefore, the proposed project would not have a significant impact at this intersection. CMP Intersections A significant impact to a CMP intersection occurs if the addition of project traffic results in: 1. Op.erations at a signalized intersection to deteriorate from LOS E under Background Conditions to LOS F under Project Conditions; or 3,3" Mr. Gary Chao April 24, 2007 Page 6 of 7 fp FEHR & PEERS r."Ns'oaJA' ION CO~SUI.JA9TS 2: Exacerbation of unacceptable operations (LOS F) at a signalized intersection by increasing the average critical delay by four (4) seconds or more and increasing the volume-to-capacity (V/C) ratio by 0.01 or more. With the addition of project traffic, the Stevens Creek Boulevard/Stelling Road intersection would continue to operate at LOS D (45.9 seconds of delay) during the AM peak hour and LOS E (72.2 seconds of delay) during the PM peak hour. The intersection would operate unacceptably during the PM pea.k hour; however, the project would not increase the average critical delay by more than four seconds or increase the v/c ratio by more than 0.01. Therefore, the proposed project would not have a significant impact at this intersection. Site Access, On-Site Circulation, and Parkinq As shown on Figure 1, full access (left and right-turns in and out) to the site will be provided via one driveway on Stelling Road. One driveway is ,sufficient to accommodate the traffic volumes generated by the project. A queuing analysis was conducted at the project driveway and a maximum queue of one vehicle inbound or outbound at the project driveway was estimated during both AM ~nd PM peak hours. The worksheets are contained in Attachment C. According to City code, twenty-two (22) feet is the required minimum two-way aisle width for 90 degree parking stalls with a parking stall width of 8.5 feet. The site plan proposes aisle widths that range from 16 to 28 feet. The proposed 24 feet aisle widths between garage openings are too narrow for larger vehicles to access the garages without making multiple point turns for ingress and egress at these locations. A turning template was used at these stalls and a passenger car was not able to access the stall without running over the curbs. We recommend that a turning templates schematic is provided by the applicant to illustrate how vehicles would access the parking spaces. /?-\ The City's Municipal Zoning Code requires 2.8 parking spaces (2 garage plus 0.8 open) for every residential/6'nit constructed. This requires the project applicant to provide a total of 62 parking spaces (22 units*2.8 spaces/unit) for the entire site. Based on the project site plan'dated January 25, 2006, the parking supply is 64 spaces (44 covered, 18 on-site including 1 handicap, and 2 off- site parking stalls). The proposed supply meets the parking requirements. However, the seven (7) parking stalls on the north and south side of the project w'ould serve small cars or motorcycles. We recommend the site plan be modified to provide adequate access to these parking spaces throughout the site. Stellina Road Access and Potential Narrowina The City of Cupertino is considering narrowing Stelling Road from four lanes to two lanes to match the existing cross-sections north of Homestead Road and south of 1-280. No conceptual or construction plans have been produced for this narrowing project. Thus, an assessment of this proposal was conducted based on traffic volumes and projected operations. A 24-hour machine count was conducted on Stelling Road south of Homestead Road on Thursday, January 25, 2007. During the AM peak-hour, 736 vehicles were counted in the southbound direction and 968 vehicles were counted in the northbound direction. During the PM peak-hour, 1,183 southbound vehicles were recorded and 822 vehicles traveled northbound. The typical capacity for a one lane road similar to Stelling Road ranges from 800 to 1,000 vehicles per ?; ;31 Mr. Gary Chao April 24, 2007 Page 7 of 7 Pp FEHR & PEERS UANSPOR fAJlON (ON ~ULJU rs hour per lane per direction depending on traffic control and other factors affecting the flow of traffic (e.g., on-street parking, the number of driveways). In general, the operations of a roadway are controlled by the operation of intersections. A roadway can operate with higher volumes if access points are limited and traffic signals provide a majority of the "green time'" on the major street approaches. The addition of a landscaped median on Stelling Road between Homestead Road and the 1-280 overcrossing was analyzed to determine its feasibility. A median would enhance the streetscape but restrict access to adjacent driveways along Stelling Road creating right in/right out driveways or allowing inbound left-turns. Outbound drivers wanting to go south on Stelling Road would be required to turn right out of the shopping center or residential development (Villa Serra) and make U-turns at Homestead Road/Stelling Road. Currently this intersection has restricted U-turn movements on all approaches. For each peak hour, the intersection could accommodate approximately 50 additional northbound U-turns and still operate with the same LOS rating under Project Conditions. The number of vehicles needing to make U-turns includes not only vehicles from the existing shopping center, but those generated by the residential development (Villa Serra) located south of the shopping center on Stelling Road. Based on the projected unacceptable intersection LOS under Background and Project Conditions during the PM peak hour, we recommend that any narrowing of Stelling Road should not reduce the capacity of any of the approaches to the Homestead Road/Stelling Road intersection. Narrowing could potentially begin 300 feet south of the Homestead Road/Stelling Road northbound stop bar and extend south to match the existing two-lane roadway section near the project site. A bus stop exists approximately 250 feet south of Homestead Road that would also need to be accommodated. We recommend that a two-way left-turn lane be maintained on Stelling Road with any narrowing project to allow left-turns to and form the commercial areas on Stelling Road. Conclusions Based on the small number of trips generated by the proposed project, operations at two nearby intersections are not expected to substantially degrade. We recommend the site plan be modified to provide adequate access to several guest parking spaces. Any narrowing of Stelling Road shall not reduce the approach lanes at Homestead Road/Stelling Road. Northbound U-turns should be allowed at Homestead Road/Stelling Road with a median island or a two-way left-turn lane should be maintained with narrowing of Stelling Road. 3'~ fP FEHR & PEERS "A.s,OtrUtoN COIIISULfA.1S ATTACHMENTS ~ "'3q fP FE H R & PEE RS rlANSPOarATJOI (ONSulf._rs ATTACHMENT A TRAFFIC COUNTS 3,<10 Traffic Data Service Campbell, CA (408) 377-2988 tdsba}@cs.com File Name Site Code Start Date Page No : 1AMFINAL : 00000001 : 1/25/2007 : 1 Start Time Factor 07:00 AM 07:15 AM 07:30 AM 07:45 AM Total 08:00 AM 13 123 57 0 193 36 138 21 0 195 50 85 63 0 198 75 154 29 0 258 844 08:15 AM 12 90 42 0 144 43 139 52 0 234 45 101 42 0 188 55 73 38 0 166 732 08:30 AM 19 72 46 0 137 51 128 28 0 207 51 154 53 0 258 36 89 22 0 147 749 08:45 AM 10 94 53 0 157 39 147 37 0 223 59 112 58 0 229 51 55 16 0 122 731 Total 54 379 198 0 631 169 552 138 0 859 205 452 216 0 873 217 371 105 0 693 3056 Grand Total 1121 708 442 0 1271 1289 1069 242 0 1600 I 298 711 398 0 14071312 696 230 0 123815516 Apprch % 9.5 55.7 34.8 0 18.1 66.8 15.1 0 21.2 50.5 28.3 0 25.2 56.2 18.6 0 Total % 2.2 12.8 8 0 23 5.2 19.4 4.4 0 29 5.4 12.9 7.2 0 25.5 5.7 12.6 4.2 0 22.4 07:45 AM 13 123 76 0 212 26 130 32 0 188 31 94 66 0 191 50 110 40 0 200 791 08:00 AM 13 123 57 0 193 36 138 21 0 195 50 85 63 0 198 75 154 29 0 258 844 08:15 AM 12 90 42 0 144 43 139 52 0 234 45 101 42 0 188 55 73 38 0 166 732 08:30 AM 19 72 46 0 137 51 128 28 0 207 51 154 53 0 258 36 89 22 0 147 749 Total Volume 57 408 221 0 686 156 535 133 0 824 177 434 224 0 835 216 426 129 0 771 3116 % Ann.

Babby, Registered Consulting Arborist April 17, 2007 1.0 INTRODUCTION I have been retained by the City of Cupertino Community Development Department to perform the following in connection with the proposed 22 lot subdivision at 10855 N. Stelling Road, Cupertino: [1] identify the species, size and condition of trees in proximity to the proposed development; [2] review the proposed landscaping plan; [3] comment on a letter by Mr. Michael Kennon of Valley Crest; and [4] provide protection measures for trees being retained. I visited the site on 4/11/07 and 4/16/07, and this report presents my analysis and recommendations. Trees inventoried for this report are situated either on the subject site or have canopies overhanging the site from neighboring properties. Small fruit trees, nut-bearing trees, and other various small trees were tallied. Documents reviewed for this report include [1] Sheet 2 (Tentative Map) by JMH Weiss, Inc., dated 1/30/07; [2] Sheet Cl (Grading and Drainage Plan) also by JMH Weiss, dated 1/25/07; [3] Sheet A1.1 (Site Plan) by Dahlin Group, dated 1/25/06; [4] Sheet L1.1 (Conceptual Site and Tree Plan) by SSA Landscape Architects, dated 1/25/07; and [5] the letter by Mr. Michael Kennon of Valley Crest (not dated). The trees' locations, approximate canopy dimensions, 1 and assigned numbers are presented on a copy of the Tentative Map in Exhibit B. 2.0 TREE COUNT AND COMPOSITION Sixteen trees of eleven various speCIes were inventoried for this report. They are sequentially numbered as 1 thru 16, and the table presented on the next page identifies their name, number and percentage. Specific information obtained for each tree can be viewed in Exhibit A (Tree Inventory Table). 1 The canopy dimensions for trees shown on the project plans are much smaller than their actual size; refer to the sizes identified within the table in Exhibit A for their spread. 10855 N.

Each is a coast live oak with trunk diameters greater than 10 inches measured at 54 inches above grade. Five trees are not shown on the project plans. They include #5, 8-10 and 16, and their locations shown on the map in Exhibit B are roughly approximate and must not be construed as being surveyed or entirely accurate. 10855 N Stelling Road, Cupertino City of Cupertino Community Development Department Page 2 of 12 3"b5 David L. Babby, Registered Consulting Arborist April 17, 2007 Tree #15 overhangs the site by approximately 10 feet and its trunk is situated on the neighboring southern property. There are an additional seven eucalyptus trees also situated on the neighboring property, however, these trees are setback a sufficient distance from the project and are not expected to be impacted. Note that one of these trees is dead and should be removed for safety purposes; it is located at the west side of the row. The site is heavily vegetated with approximately 57 additional small trees which are fruit- bearing, nut-bearing, and other various types. Due to their amount, I tallied (rather than inventoried) each one and the following list identifies their species and amount: · Thirty-three flowering plums (Prnnus sp.) · One avocado (Persea americana) · Two orange trees (Citrns sinensis) · Three holly oaks (Quercus ilex) - one to two inches in diameter · Eight olive trees (Olea europaea) · Seven loquat (Eriobotryajaponica) · Two English walnuts (Juglans regia) · One tree-of-heaven (Ailanthus altissima) 3.0 SUITABILITY FOR TREE PRESERVATION Each tree has been assigned either a "high," "moderate" or "low" suitability for preservation rating as a means to cumulatively measure their physiological health, structural integrity, location, size and specie type. These ratings and applicable tree numbers are presented below; note that the "high" category is comprised of two trees, the "moderate" category six trees, and the "low" category eight trees. Hi2h: Applies to trees #4 and 6. They appear vigorous, in stable condition, and have a high potential of providing a long-term contribution to the site. 10855 N Stelling Road, Cupertino City of Cupertino Community Development Department Page 3 of 12 ?.{,~ David L. Babby, Registered Consulting Arborist April 17, 2007 Moderate: Applies to trees #1, 2,5, 10, 12 and 13. They appear worthy of retention, but their longevity and contribution is less than those of high suitability and more frequent care is needed during their remaining life span. Low: Applies to trees #3, 7-9, 11 and 14-16. These trees are either dead or predisposed to irreparable health problems and/or structural defects that are expected to worsen regardless of measures employed. 4.0 PROJECT REVIEW 4.1 Proposed Tree Removals The proposed plans indicate that all trees on-site, but #4, will be removed; this includes trees #3, 5, 7-14 and 16. Tree #4 is a large and healthy date palm proposed for relocation; it is approximately 40 feet tall and has a stout 3~-inch trunk diameter. Based on my evaluation, I fmd that the loss of all trees proposed for removal but #1, 2 and 6 would conform to Section 14.18.180 (Review Standards) of the City Ordinance. Trees #1, 2 and 6 are all coast live oaks and regulated by City Ordinance; their respective trunk diameters are 22.5, 21 and 16.5 inches. To achieve their adequate protection, the proposed design will need to be revised so no grading, trenching (e.g. drainage, utilities, etc.), or soil disturbance (including any overcut), occurs within a minimal distance from the trunks of five times their diameter when only one side is impacted, and seven times their diameter when two or more sides are impacted. Finish grading should also be avoided within these setbacks; if this is not possible, the work should be reviewed for impacts prior to project approval. In addition to the above setbacks, the homes should be established a minimum distance from the trunks of five times their diameters. Additionally, they should be designed so that sufficient clearance from the canopies, including scaffolding, is achieved to the 10855 N. Stelling Road, Cupertino City of Cupertino Community Development Department Page 4 of 12 3"b 1 David L. Babby, Registered Consulting Arborist April 17, 2007 extent that their form can remain intact (this should be determined and verified on-site by the architect). I recommend the roofs are also pitched away from the trees. I also recommend the sections of new homes constructed within a minimal distance from the trunks of ten times their diameters (e.g. a 24-inch diameter tree would have a 20-foot distance) should be established on a pier and above-grade beam foundation in which the beam is literally established on top of or above existing soil grade and no excavation occurs except for the piers (i.e. a no-dig design). Any fill placed around the foundation should not extend beyond 24 inches from its edge. Regarding the future driveway, it should be fully pervious (including base material) and established at least five to six feet from tree #2's trunk. Additionally, any section within 15 feet from the trunk should be established on top of existing soil grade (to include base materials, curb, gutter and edging) with no more than a four-inch vertical soil cut. To help achieve this design, Tensar@ BX Geogrid (www.tensarcorp.com) should be considered. 4.2 ReplacementlMitigation Strategy I recommend mitigation for all trees to be removed except for #9 (dead poplar) and #11 (pine falling over). A strategy for mitigating the loss of trees #3, 5, 7, 8, 10, 12-14 and 16 includes the installation of one tree of 36-inch box size for each one removed, which would account for nine new trees of 36-inch box size. In the event trees #1, 2 and/or 6 were approved for removal, a strategy to mitigate their loss involves the installation of two trees of 48-inch box size per each removed. Please note that due to the site constraints and relatively minimal planting space, the installation of large specimen (i.e. field-grown) oak trees does not appear feasible, except possibly in the common area at the end of the driveway; however, if a large coast live oak was planted there, the turf would need to be omitted from the design. Regarding the relocation of trees #1, 2 and/or 6, I do not fmd trees #1 and 2 are viable candidates due to their condition and unfavorable height reduction for overhead power 10855 N Stelling Road, Cupertino City of Cupertino Community Development Department Page 5 of 12 ~'''6 David L. Babby, Registered Consulting Arborist April 17, 2007 line clearance. However, tree #6 is a potential viable candidate to relocate at the common area at the end of the driveway; in doing so, the turf must be omitted from the design and the palm tree carefully placed to avoid deterring the future growth and natural form of the oak. 4.3 Applicant's Arborist Letter Regarding the letter by Mr. Kennon of Valley Crest, he provides statements regarding trees assigned #2 and 4. Tree #4 is the tall date palm and he recommends it be relocated elsewhere on-site; the plans indicate this will occur and I agree with this course of action. Tree #2 is a 21-inch diameter coast live oak that he recommends for removal due to its location beneath the power lines and its poor structure. I acknowledge that the tree is situated beneath the power lines and has been undesirably pruned over the years to achieve power line clearance, an action that will continue to occur throughout the tree's life span. I also acknowledge that the tree's structural integrity is poor partly due to past pruning activities and partly due to the weak attachment of the two western leaders. However, even with considering these items, I recommend it is retained and designed around for the following reasons: [1] the tree appears very healthy and capable of serving as a valuable and irreplaceable amenity to the site and neighborhood for the foreseeable future, and [2] criteria set forth within Section 12.18.180 (Review Standards) of the City's Ordinance does not seemingly support its removal. 4.4 Landscape Plan The proposed landscape design is identified on Sheet Ll.l (Conceptual Site and Tree Plan) and my comments are as follows: . Two date palms (Phoenix dactylifera) are proposed for installation at the front entrance on each side of the future driveway. Overhead at these locations are the high-voltage electrical lines routed north to south along the front of the property. As this type of tree can reach a height of about 65 feet, they would not be appropriate at their proposed location. 10855 N Stelling Road, Cupertino City of Cupertino Community Development Department Page 6 of 12 3/hq David L. Babby, Registered Consulting Arborist April 17, 2007 · The relocated palm (tree #4) is proposed for relocation about one-foot from a future walkway. Given the tree's size, it will need much more space than this upon being replanted, and in doing so, should be shifted further east and possibly the turf area reduced in size; a professional tree moving company should be consulted in identifying the space required for proper installation, watering and drainage to achieve the greatest success for long-term survival. · Regarding trees proposed for installation, it is my oprmon that they are appropriately selected for a condominium development site and will provide an outstanding, immediate and future tree landscape that can potentially thrive into the distant future. Additionally, I fmd that the quantity, type and size of trees favorably exceed mitigating those approved for removal. 5.0 RECOMMENDATIONS Recommendations presented within this section serve as guidelines for achieving adequate protection of trees that will be retained. They should be carefully followed and incorporated into construction plans. Please note that any or all recommendations are subject to revision upon reviewing any revised plans. 5.1 Design Guidelines 1. The location, accurate canopy dimension, and assigned number of each inventoried tree should be shown on Sheets C1.0, Sheet 2, and L1.1. I also recommend the location, number and canopy dimension of each retained tree is shown on Sheet A 1.1. 2. Recommendations presented in Section 4.0 of this report should be followed to achieve the retention and protection of trees #1,2 and 6. 3. On Sheets Cl.O, Sheet 2, and L1.1, I recommend an "X" is placed through each trunk proposed for removal. 10855 N Stelling Road, Cupertino City of Cupertino Community Development Department Page 7 of 12 3,10 David L. Babby, Registered Consulting Arborist April 17, 2007 4. Walkways proposed beneath canopies of the oaks should be established entirely on top of existing soil grade (including curb, gutter, edging and forms). Any necessary vertical cut (though not advised) should not exceed four inches below existing soil grade. Additionally, direct compaction of the existing soil surface (i.e. sub grade) must be avoided (the subbase materials can be compacted, just not the subgrade). 5. The block wall proposed around the perimeter of the site and within a distance from the oak trees' trunks of 10 times their diameters must be of a pier and above-grade beam design in which spans between the piers are literally established above existing grade so no soil disturbance or excavation occurs between the piers. 6. This report and any supplemental letters shall be incorporated into the [mal set of project plans, titled Sheets T -1, T -2, etc. (Tree Protection Instructions), and referenced on all site-related plans (i.e. Sheets 2, C1.0, A1.1 and L1.1). 7. The permanent and temporary drainage design for the project should not require water being discharged beneath the trees' canopies. 8. Any revised plans should be reviewed for tree-related impacts prior to approval. Additionally, upon availability, the underground utility and irrigation design should also be reviewed. 9. The proposed landscape design should conform to the following guidelines: a. Turf and plant material should be avoided beneath the oak canopies; as an alternative, I suggest a four-inch layer of coarse wood chips (decorative or from a tree company). b. Irrigation beneath the oak canopies can impose adverse impacts and should be avoided. If applied, it should be low-volume, applied irregularly (such as only once or twice per week), temporary (such as no more than three years), and not strike within five feet of its trunks. Irrigation should not strike the trunks of any other trees (new or existing). 10855 N. Stelling Road, Cupertino City of Cupertino Community Development Department Page 8 of 12 3~11 David L. Babby, Registered Consulting Arborist April 17, 2007 c. Trenching for irrigation or lighting should be avoided beneath the canopies. If necessary, they should be routed in a radial direction to the trunks. d. Stones, mulch and fencing should not be placed against the trunks of existing or new trees. Plastic ground cover should also be avoided beneath canopies. e. Tilling beneath canopies should be avoided, including for weed control. f. Bender board or other edging material proposed beneath the canopies should be established on top of existing soil grade (such as by using vertical stakes). 10. To achieve the greatest assurance of proper installation, all new trees shall be installed, including necessary irrigation, by an experienced and knowledgeable state-licensed landscape contractor (or a professional tree company). The work shall be performed to professional industry standards. 5.2 Protection Measures before and during Development 11. Due to the close proximity of activities among trees, a "project arborist,,2 should be retained by the applicant or owner to assist in implementing and achieving compliance with all tree protection measures. 12. Prior to any grading, trenching or site clearing work, a pre-construction meeting shall be held on-site with the project arborist and contractor to discuss work procedures, protection fencing locations, limits of grading, staging areas, routes of access, supplemental watering, mulching, locations for equipment washing, and other tree protection measures. 13. Tree protective fencing shall be installed prior to any grading, trenching or site clearing work, and its precise location must be determined and its placement approved by the project arborist prior to the issuance of any grading or construction permit. It shall be comprised of six-foot high chain link mounted on eight-foot tall, two-inch diameter steel posts that are driven 24 inches into the ground and spaced no more than 10 feet 2 The "project arborist" refers to an individual that is certified by the International Society of Arboriculture (ISA) and/or is a member of the American Society of Consulting Arborists (ASCA). 10855 N. Stelling Road, Cupertino City of Cupertino Community Development Department Page 9 of 12 3---12 David L. Babby, Registered Consulting Arborist April 17, 2007 apart. Once established, the fencing must remain undisturbed and be maintained throughout construction until [mal inspection. Please note that fencing will need to be established in two or more phases (e.g. once for demolition, once for construction, and possibly again for installing the driveway). 14. Unless otherwise approved, all development activities must be conducted outside the fenced areas (even after fencing is removed) and off unpaved areas beneath the canopies of Ordinance-size trees inventoried and not inventoried for this report. These activities include, but are not limited to, the following: demolition, grading, stripping of topsoil, trenching, equipment cleaning, stockpiling/dumping of materials, and equipment/vehicle operation and parking. 15. Any approved digging or trenching beneath a canopy shall be manually performed. In the event roots of two inches and greater are encountered during the process, the project arborist shall be consulted for appropriate action. 16. Prior to grading or excavating soil beyond a distance of 10 times the trunk diameters, a one-foot wide trench should be manually dug along the perimeter of a foundation or patio for the entire distance. The trench should be dug to the required depth, and shall occur where excavation will occur closest to the trunk. Any roots encountered during the process should be cleanly severed against the soil cut. Roots with diameters of two inches and greater should be treated according to the project arborist. 17. Overcut should not exceed a distance of 24 inches from a foundation or utility trench. 18. Prior to construction, I recommend a four-inch layer of coarse wood chips (~- to %- inch in size) is manually spread on unpaved soil beneath the trees' canopies. These . chips must not be placed against the trees' trunk, should remain throughout construction, and can be obtained from a tree service company and/or by contacting www.reuserinc.com. 10855 N Stelling Road, Cupertino City of Cupertino Community Development Department Page 10 of 12 3,'13 David L. Babby, Registered Consulting Arborist April 17, 2007 19. Any approved activity required beneath a tree's canopy (within and beyond the designated fenced areas) must be performed under direction of the project arborist. 20. All existing, unused lines or pipes .beneath the canopies of retained trees should be abandoned and cut off at existing soil grade. 21. Piers or post-holes (whether for the walls, fencing or structures) should be established as far from the trees' trunks as possible where within a distance of lO times the trunk diameters. For digging the first three feet below grade, I recommend a post-hole digger is used; in the event a root two inches and greater in diameter is encountered, the hole should be resituated. Digging below three feet from grade can be drilled. 22. Soil extracted from any pier hole or trench should not be placed against a tree's trunk, or remain on undisturbed ground beneath a canopy. 23. Each recommendation that is presented within Section 5.1 of this report and IS applicable to the actual development of the site shall be followed. 24. Throughout development, supplemental water should be supplied to the retained trees; the proj ect arborist shall determine the specific trees, intervals, amounts and application methods. 25. The relocation of tree #4 (and tree #6, if applicable) must be performed by a professional tree service company experienced with relocating trees, and under the supervision of an individual certified by the International Society of Arboriculture (ISA); all recommendations provided by the company to achieve successful transplant are followed. 26. The pruning and removal of trees shall be performed under the direction of the project arborist. The work must be performed under the supervision of an individual certified by the ISA (and not performed by construction personnel).

Not to Scale D N 7~1q Page 1 ot L Gary Chao From: Arbor Resources [arborresources@comcast.net] Sent: Saturday, May 19, 2007 10:13 AM To: Gary Chao Subject: 10855 N. Stelling Road Gary , I have reviewed the revised set of plans for this project and my comments are as follows: Tree #1: 22.5-inch diameter Coast Live Oak Plans identify retaining this tree; it appears this can likely be achieved provided the section of porch within eight feet of its trunk is eliminated from design. Also, great care will be necessary during pruning so the tree's form remains intact. To accurately identify how much of the canopy will require removal for construction, I recommend the tree is viewed again once story-poles can be erected, including for the porch. Tree #2: 21-inch diameter Coast Live Oak It appears likely that this tree can be retained, though the front of the home will be "tucked" tightly under its canopy. Great care during the tree's pruning is also essential, and the construction team will need to work close to the branches during construction, particularly for exterior finishing work. A clear depiction of how the home will interface with the tree's canopy can be provided upon story-poles are erected, including for the porch. Tree #6: 16.5-inch diameter Coast Live Oak This tree is proposed for relocation within the common area at the end of the driveway. However, several modifications to the landscape design are necessary to protect the tree and promote a suitable growing environment. One involves either eliminating the decomposed granite (d. g.) walkway within eight feet of the trunk, or shifting the tree closer towards the street. I favor shifting the tree closer towards the street to also allow for the date palms to grow without interfering with branches of the oak, and thus affecting the oak's ability to prosper in its growth and natural form (another option is to eliminate the date palms from the design in that area). Placement of the oak in relation to the walkway should also co nsider a pedestrian walking without interference of large, overhead limbs (such as those greater than four inches in diameter). Another modification involves the proposed turf. Because coast live oaks do not favor frequent watering of their root zone (except during times of significant root loss, which will occur from 6/21/2007 8/61 Page 2 of2 relocation), I recommend no turf is proposed within 15 feet from the tree's trunk (this is a minimum distance; possibly the entire turf area should be omitted to consider the long-term). Plants proposed within 15 feet from the trunk should also be drought-tolerant. The ground within eight feet of the trunk should contain no d.g. Rather, a four-inch layer of decorative wood chips should be spread on the ground and extend to 15 feet from the trunk (note that bark and gorilla hair should be avoided). Tree #4: Canary Island Date Palm The proposed location for the existing large palm will provide insufficient space for its successful relocation (e.g. root ball size, watering and drainage elements). Based on the site density, it does not appear possible to retain this tree. If this tree is to remain, an ISA certified arborist with a professional tree moving company, such as. Valley Crest, should be consulted in identifying the space required for proper installation, watering and drainage to achieve the greatest success for long-term survival. Proposed Trees The current landscape plan identifies one date palm would be installed in front of the property on the south side of the driveway. Overhead are high-voltage electrical lines, and as the tree can reach a height of about 65 feet, this tree is not appropriate and would ultimately be killed as cutting of its top would result in its demise. The African sumacs proposed along the front of the property are inherently prone to branch and limb failure, require frequent pruning, and have short-life spans. Additionally, they do grow wide canopies and would immediately conflict with the front porches and homes. For these reasons, I recommend they are not selected. I also do not suggest the installation of the date palms along the buildings. At only two feet away, it seems that the tree will become an increasing conflict to the homes, and provide a safety issue as the trees mature. Possibly a more narrow and columnar tree should be considered if the desire is to plant trees against the buildings. David L. Babby, RCA Consulting Arborist 650-654-3351 6/21/2007 ?"B.:?

This report presents the results of the noise study, which includes on-site noise monitoring, projection of future Ldn proj ect noise levels, a description of architectural details relevant to noise protection performance, and general recommendations for compliance with City of Cupertino planning criteria [1] and California Title 24 Noise Insulation Standards [2]. PROJECT DESCRIPTION [3] The proposed Las'Palmas residential development includes 9 three-bedroom attached units, 4 four-' bedroom attached units, and 8 four-bedroom detached units, with 2-car garages on the ground floor in'each unit, plus an additional 19 visitor parking spaces on site. The project site is on a 1.2-acre site bounded on the', north by a church property, on the south by freeway 1-280, on the east by North Stelling Road, and on the east by a utility facility. There will be a single access road from North Stelling Road. At present there are two residential buildings on the site, which will be demolished. This report evaluates, the complete build-out scenario. SUMMARY OF FINDINGS The primary source of noise at the east side of the project site is traffic on North Stelling Road adjacent to the site to the east and also the 1-280 freeway to the south. The freeway is depressed approximately 20 feet relative to the site elevation. Typical vehicle passby noise levels on site are 60-70 dBA at 50 feet near Stelling Road. Tnlcks, motorcycles, and poorly muffled vehicl~s produce peak levels 5 to 10 dBA higher on passby. There are no other significant noise sources in the project area, except routine sporadic noises, such as garbage collection. . Based upon site noise measurements, anticipated future traffic volumes, and noise modeling, the worst- case Design Noise Level for project residential units would be 78 dBA, with the installation of a noise barrier on the south property line. The Design Noise Level is the worst-case outdoor noise level the project structures with the highest noise exposures must mitigate to provide a satisfactory interior environment. To meet City of Cupertino residential noise criteria, described in the Noise Element of the Cupertino General Plan [1], the following general design measures must be met: . Title 24-specifies long-term interior noise levels not exceeding 45 Ldn due to exterior sources. Environmental Consulting Services * * * Saratoga .;~B5 Las Palmas Residential Noise Study - North Stelling Road, Cupertino Page 2 of6 . Party wall assemblies between attached residential units, must have a n1inin1un1 50 STC (SQund Transn1ission Class) rating. Standard STC ratings for different types of party wall constnlctions are docun1ented in References 6 and 7. . Floor/ceiling assemblies between attached residential units should have a 111ini111un1 50 IIC (I111pact Insulation Class) rating, as well as a 50 STC rating. (This regulation does not apply to this project, since the attached units are townhouses and have no floor/ceiling assemblies between residential units. ) . . According to Cupertino Noise Element standards, the outdoor residential environlnent should be protected to a level of 60, dBA Ldn [1], if possible with reasonable measures. NOISE MONITORING AND DESIGN NOISE LEVEL ANALYSIS' Fiel,d nC?ise measurements on site were made during the morning commute period of March 2,2007, with a CEL-440 precision noise meter and analyzer, calibrated with a B & K Model 4230 Sound Level Calibrator. The measurement locations were chosen to represent the worst-case exposure of the residential units closest to the two major traffic sources bOlmding the project. Location 1 ~,the location of the northeast comer of the site at Building 3, one of the nearest residences to North Stelling Road, about 50 feet from the'nearest lane Location..2 - the location of the southeast corner of the site. at Build~ng 4, one of the n~ares~ residences to North Stelling Road, about 35 feet ,from the' nearest lane, and also adjacent to 1-280 freeway, approximately 80 feet from the nearest lane Location 3 ~ the location of the southwest corner of site at Building 12, adjacent to 1-280 freeway, approximately 90 feet from the nearest lane Existing N oiseLevels N oise.levels w"ere measured and are reported using pergentile noise descriptors: L90 (the background. . noise level exceeded 90 % of-the time), L50 (the median noi~e level exceeded 500/0 of the time), L1 (the peak level exceeded 1 % of the time), and Leg (the average energy-equivalent'noise level). Measured noise levels, are presented in Exhibit 1 below. The Ldn noise levels were computed as.the long-term average:ofLeq using the typical daily traffic distribution in the area, with standard weighted penalties for the nighttime hours.

S~elling traffic noise and steady background 1-280 noise, although it is partially shielded by the Stelling Ro"ad bridge from some freeway noise. Location 3 represents the worst-case residential noise exposure on the project site for the units directly adjacent to and with a view of freeway 1-280 traffic. Environmental Consulting Services * * * Saratoga 3/eft, Las Palmas Residential Noise Study - North Stelling Road, Cupertino Page 3 of 6 Future Project Noise Levels ,The D~sign Noise Level is the outdoor noise level anticipated within the next ten years (2017) for the residential units experiencing the highest noise exposure-the maximum noise level that the building stnlctures must mitigate. In this project the units closest to North Stelling and 1-280 would be exposed to the highest traffic noise levels, the Design Noise Level (DNL). Units partially protected by other buildings will have noise levels at least 8-10 dBA less. The DNL is computed based on field measurements of present noise levels, projections of future traffic noise increases, and modeled by an enhanced version of the National Cooperative Highway Research Board traffic noise model [5]. Existing daily traffic volumes are approximately 140,000 on 1-280 near the project, based on CALTRANS online counts [4]. Daily volumes on North Stelling Road are approximately 15,300 based on City traffic counts from year 2002 [4] and informal ECS counts during field work. It is assumed that traffic will increase a modest 2% per year, which would produce a total increase of22% over the next ten years on N. Stelling and 1-280 freeway, including project-generated trips. WIth the expected increase in traffic on 1-280 and N. Stelling, noise modeling provided the anticipated 2017 project noise levels shown in Exhibit 2, an increase of less than 1 dB over present noise levels on 1-280 and about a 1 dB increase on N. Stelling Road, including project trips. Site noise levels would be highest at the residences in the southwest comer of th.e site that are subj ect to significant direct noise from freeway, as well as those near and facing N. Stelling,'particularly those rooms facing the roadways. In addition, exposures at the upper floor windows would be approximately 2 dB.higher than ground-floor noise levels b'ecause 'of increased direct reflections from the road surface. A masonry noise wall along the freeway property line is standard design procedure, but for comparison future noise levels without a noise wall are given in the 2nd and' 4th columns of Exhibit 2.

Units on interior of site 62-68 56-60 . 62- 70 60-66 Several elements contribute significantly to the noise levels at the plann~d units: the unit pla~ements and their relationship to the adjacent road and the freeway (with the location of a noise wall on the property line only 10-12 feet from the nearest structures), the living spaces on the 2nd and 3rd levels. With this site geometry, a noise wall will only provide noise protection at the ground level and very little at the 2nd and 3rd floor elevations. That is, even if a 1 a-foot wall is constructed, little noise protection would be pr'ovided to the . windows on the upper floors. Therefore an eight-foot noise barrier would be reconlffiended on the freeway property line, which will reduce ground level traffic noise levels by 8-10 dBA. The resulting noise levels are shown in columns 3 and 5 of Exhibit 2, which shows that the estimated worst-case noise levels for units closest to and facing the freeway, the architectural Design Noise Level, would be 78 dBA for upper floor units. Areas further back from the roads, such as the interior areas, would have significantly lower noise levels than those near the freeway and N. Stelling Road. Environmental Consulting Services * * * Saratoga 1;-,,81 Las Palmas Residential Noise Study - North Stelling Road, Cupertino Page 4 of6 It should be noted that to protect units near the west end ofth~. noise barrier, the barrier should be extended about 80 feet along the freeway property line on the west end. Otherwise the freeway noise has a direct short path to the units around the end of the noise barrier, raising noise levels significantly in the area. As' in any neighborhood, some non-traffic activities could cause sporadic disturbance to the project. However, the proximity to steady arterial traffic would provide a noise background covering most incidental noise on adj acent properties. STATE OF CALIFORNIA and CITY OF CUPERTINO RESIDENTIAL NOISE STANDARDS Existing noise criteria [1,2], require that new residential housing developments provide an interior Ldn noise level of 45 dBA or less due to exterior noise sources. As described in the previous section, the worst- case project noise environment for architectural design purposes is 78 dBA for units adjacent to 1-280. Therefore, to achieve an interior Ldn of 45 dBA, a minimum noise reduction of at least 33 dB must be provided by the combined elements of the building shell, particularly those units near the freeway. The transmission loss of architectural building elements is designated by Sound Transmission Class (STC) ratings for wall elements and by Impact Insulation Class (IIC) ratings for floC?r/ceiling assemblies, both o~ which are methods of estimating the inherent ability to attenuate 'noise transmission. Residences away from both traffic sources would have noise exposure levels much lower due to both distance and shielding effects. . . Standard wood and gypsum exterior wall constructions have STC ratings of approximately 40 dBA or more. Standard hollow-core doors and openable single pane windows are rated at. about 2~-28 8TC. Typical -. dual-layer thermal pane windows are rated at 27-30 .dB STC. Except f<;>r actual cracks and openings in.a structure, doors and windows are usually the weakest elements in the design and construction of a good soup.d-rated building, and usually reduce the overall protection provided by the m?re substantial wall structures. RECOMMENDATIONS ".... . Following are recommendations for meeting the primary criteria for good resiqept~al noise insulation design by .the North Stelling Road residences development: '1. WINDOWS. Windows in units adj'acent to and with a view of 1-280 should have'STC ratings ofiat 'least 33 dB. 'Speci:al acoustical windows, with larger air spaces between panes, or with a thin', ' plastic laminate layer between glass layers, can be obtained with STC ratings of 33-38 STC, which would meet the requirement. . A'window STC rating of 29-30 would be acceptable for units located away from 1-280, for general . noise protection and to reduce peak noise levels from motorcycles and trucks. High quality double-glazed thermal windows, with two 1/8" lights separated by a 3/8" to 3/4" air space, and good weather seals if openable, have ratings of 27 -30 STC. 2. P ARTY WALL ASSEMBLIES. For minimizing noise transmitted between attached residential units, the party wall assembly should have several inches of air space, fiberglass insulation and minimal structural connections, and generally resilient channel (RC) attached to one side of the party wall, in order to meet the 50 dBA STC requirement. Acceptable types of party wall assemblies are described in References 6 and 7. In addition, any fire stops between units should not provide a strong structural connection. That is, they should be of lightweight material, such as sheet metal or fiberglass that cannot conduct low- frequency sound and vibration between units. 3. EXTERIOR DOORS. Entrance doors and sliding glass doors, particularly those in Tesidences near and facing the freeway and North Stelling Road, should meet an STC rating of at least 25-27 dB to match the building shell noise reduction criteria. Environmental Consulting Services * * * Saratoga 3,eB Las Palmas Residential Noise Study - North Stelling Road, Cupertino Page 5 of6 4. OUTDOOR ACTIVITY AREAS. The residential buildings on the perimeter of the site near the two traffic noise sources will provide significant noise protection to interior yards, balconies and patios behind the buildings. Therefore noise levels in much of the interior of the site will be in the 55-60 dBA range, meeting general City planning targets for the residential environment. 5. VENTILATION. Mitigation of outside traffic noise is based upon windows that are closed in order to provide the required noise protection. .Therefore all units, particularly those units nearest the traffic noise sources producing the primary noise, must have a ventilation system that provides a habitable interior environment with the windows closed, regardless of outside temperature. In addition, if air conditioning units are installed, the noise levels produced by the AC units must not themselves cause a noise problem for any of the residential units associated with the project or adj acent residential properties. 6. GENERAL DESIGN AND CONSTRUCTION PRACTICES. Good noise design must be implemented by good field construction practices or the design performance will not be achieved. This includes minimizing all penetrations of al1d connections between party wall and floor/ceiling assemblies, and acoustical sealant around any necessary penetrations.
