As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Point sources are discrete conveyances such as pipes or man-made ditches. Individual homes that are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit; however, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters. In most cases, the NPDES permit program is administered by authorized states. Since its introduction in 1972, the NPDES permit program is responsible for significant improvements to our Nation's water quality. WHAT CAN I FIND ON THIS WEB SITE? The site contains technical and regulatory information about the NPDES permit program. The NPDES Permits Program consists of a number of programs and initiatives. Links to each of these programs and initiatives are located on the right navigational bar. For information on specific facilities with NPDES permits, there are several EPA public search tools that may be helpful: Enforcement and Compliance History Online ECM - The public access website to data stored in EPA's compliance and enforcement data systems, including [CIS-NPDES for facilities regulated under the CWA NPDES program. ECHO allows users to find and download information on permit data, inspections, violations, enforcement actions, and penalties. The ECHO website was recently modernized and redesigned to make it easier to use and maintain. The modernized search for Clean Water Act facility search, effluent charts, and water quality data. Envirofacts - A single point of access to select U.S. EPA environmental data. This website provides access to several EPA databases to provide you with information about environmental activities, including those that affect water. Under "System Data Searches", a user can retrieve facility data from ICIS- NPDES. Specify the facilities by using any combination of facility name, permit number, location, industrial classification, and chemicals. http://water.ei)a.gov/Dolwaste/nodes/ Page 2 of 4 1 7 /A /) n l c Municipal Separate Storm Sewer System (MS4) Main Page C Stormwater < US EPA LEW i OF.? 3 of *4 A �pd3rmti http:/hvater.epa.gov/palwaste/npdes/stormwater/Municipal-SeparateStorm-Sewer-System-MS4-Main-Page.cfm *' SY r'MIa1 hCtlyv Water: Stormwater You are here: Water»Pollution Prevention_& Control *Permitting (NIPDES) *Stormwater*Municipal Separate Storm Sewer System (MS4) Main Page httn-/AIImts-r ana Qtnr Qoiaror Qvctorn 1 1 /A /101 C Municipal Separate Storm Sewer System (MS4) Main Page I Stormwater I US EPA Page 2 of 6 Municipal Separate Storm Sewer System (MS4) Main Page OVERVIEW Polluted stormwater runoff is commonly transported through Municipal Separate Storm Sewer Systems (MS4s), from which it is often discharged untreated into local waterbodies. To prevent harmful pollutants from being washed or dumped into an MS4, operators must obtain a NPDES permit and develop a stormwater management program. • Phase 1, issued in 1990, requires medium and large cities or certain counties with populations of 100,000 or more to obtain NP DES permit coverage for their stormwater discharges.There are approximately 750 Phase I MS45. • Phase 11, issued in 1999, requires regulated small MS4s in urbanized areas, as well as small MS4s outside the urbanized areas that are designated by the permitting authority, to obtain NPDES permit coverage for their stormwater discharges. There are approximately 6,700 Phase II MS4s. Generally, Phase I MS4s are covered by individual permits and Phase II MS4s are covered by a general permit. Each regulated MS4 is required to develop and implement a stormwater management program (SWMP) to reduce the contamination of stormwater runoff and prohibit illicit discharges. WHAT IS AN MS4? An MS4 is a conveyance or system of conveyances that is: • Owned by a state, city, town, village, or other public entity that discharges to waters of the U.S.; • Designed or used to collect or convey stormwater (including storm drains, pipes, ditches, etc.); • Not a combined sewer; and • Not part of a Publicly Owned Treatment Works (sewage treatment plant).

The RMC includes the following participants: • Clean Water Program of Alameda County (ACCWP) • Contra Costa Clean Water Program (CCCWP) • San Mateo County Wide Water Pollution Prevention Program (SMCWPPP) • Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) • Fairfield -Suisun Urban Runoff Management Program (FSURMP) • City of Vallejo and Vallejo Sanitation and Flood Control District (Vallejo) This Urban Creeks Monitoring Report complies with the MRP Reporting Provision C.8.g.iii for reporting of all data collected pursuant to Provision C.8 in Water Year 2014 (October 1, 2013 through September 30, 2014). Data presented in this report were produced under the direction of the RMC and the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) using probabilistic and targeted monitoring designs as described herein. In accordance with the BASMAA RMC Multi -Year Work Plan (Work Plan; BASMAA 2011) and the Creek Status and Long -Term Trends Monitoring Plan (BASMAA 2012), monitoring data were collected in accordance with the BASMAA RMC Quality Assurance Program Plan (QAPP; BASMAA, 2014a) and BASMAA RMC Standard Operating Procedures (SOPS; BASMAA, 2014b). Where applicable, monitoring data were derived using methods comparable with methods specified by the California Surface Water Ambient Monitoring Program (SWAMP) QAPP2. Data presented in this report were also submitted in electronic SWAMP -comparable formats by SCVURPPP to the San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) on behalf of SCVURPPP Co -permittees and pursuant to Provision C.8.g.ii. I The San Francisco Bay Regional Water Quality Control Board (SFRWQCB) issued the MRP to 76 cities, counties and flood control districts (i.e., Permittees) in the Bay Area on October 14, 2008 (SFRWQCB 2009). The BASMAA programs supporting MRP Regional Projects include all MRP Permittees as well as the cities of Antioch, Brentwood, and Oakley, which are not named as Permittees under the MRP but have voluntarily elected to participate in MRP -related regional activities. 2 The current SWAMP QAPP Is available at: htto./twww.waterboards.o.govFwatgr issues1pMgramslswamo/docs/gaoolsMmo aaco master040108a.ndi CDS - Stormwater Treatment from Contech CDS° Stormwater Treatment The CDS hydrodynamic separator uses swirl concentration and patented continuous deflective separation to screen, separate and trap trash, debris, sediment, and hydrocarbons from stormwater runoff.

The indirect screening capability of the system allows for 100% removal of floatables and neutrally buoyant material debris 2.4mm or larger, without binding. CDS retains all captured pollutants, even at high flow rates, and provides easy access for maintenance. CDS is used to meet trash Total Maximum Daily Load (TMDL) requirements, for stormwater quality control, inlet and outlet pollution control, and as pretreatment for filtration, detentionrnfiltration, bioretention, rainwater harvesting systems, and Low Impact Development designs. How CDS Treats Stormwater ■ Stormwater enters the CDS through one or multiple inlets and/or a grate inlet. • The inlet flume guides the treatment flow into the separation chamber where water velocities within the chamber create a swirling vortex. ■ Water velocities in the swirl chamber continually shear debris off the treatment screen, making it the only non -blocking screening technology available in a hydrodynamic separation system. • The combination of swirl concentration and indirect screening force floatables and solids to the center of the separation chamber trapping 100% of floatables and neutrally buoyant debris larger than the screen aperture. • Sediment settles into an isolated sump while floatables and neutrally buoyant pollutants are captured in the separation cylinder. All pollutants remain in these sections of the unit until they are removed during maintenance. • Stormwater then moves under the hydrocarbon baffle, and the treated water exits the system. The baffle acts as a wall for hydrocarbon containment. It contains previously captured hydrocarbons and prevents the agitation of hydrocarbons when high -flows spill over the diversion weir. • During high-intensity events, the internal diversion weir directs a portion of flows greater than the design storm around the treatment chamber and over an internal bypass weir. ■ Treated stormwater exits the CDS via the outlet pipe.

The small footprint of the VortSentry HS makes it an effective Stormwater treatment option for projects where space is at a premium. http://www.conteches.com/Products/Stormwater-ManagementITreatmentfVortSentry-HS 11/7/2015 VortSentry HS - Stormwater Treatment from Contech The VortSentry HS accepts a wide range of pipe sizes to treat and convey a wide range of flows. The unique internal bypass weir allows flows exceeding the treatment capacity to be diverted within the unit eliminating the need for an external bypass structure. How the VortSentry HS Treats Stormwater ■ Untreated stormwater enters the VortSentry HS through an inlet pipe or grate inlet. ■ Low, frequently occurring storm flows are directed to the treatment chamber where a tangentially oriented downward pipe induces a swirling motion in the treatment chamber that promotes the separation of suspended solids. Trash and floating debris are also captured in the treatment chamber. ■ Moderate storm flows are directed into the treatment chamber through a secondary inlet, which allows for capture of floating trash and debris. The secondary inlet provides for treatment of higher flows without significantly increasing the velocity or turbulence in the treatment chamber. ■ Flow exits the treatment chamber through the outlet flow control, which manages the amount of flow that is treated and helps maintain the helical flow patterns developed within the treatment chamber. ■ Flows exceeding the system's rated treatment flow are diverted away from the treatment chamber by the flow partition. ■ Treated Stormwater exits the VortSentry HS via the outlet pipe.

The group, San Francisco Baykeeper, said San Jose has had 780 sewage spills over the past five years, and has allowed tons of trash to flow into the Guadalupe River and Coyote Creek through its storm drain system. The city has missed key deadlines for action, the group contends; has violated various permits; and has fecal coliform and other pollutants that far exceed health standards in its creeks. Trash in Coyote Creek in San Jose (San Francisco Baykeeper) "San Jose is a hot spot for trash pollution and bacterial pollution into the bay," said attorney Sejal Choksi, program director for Baykeeper. "Its leaders have not taken care of the problem or prioritized the issue. We've seen the trash, we've measured the bacterial pollution. What they are doing is not sufficient." City leaders said they were surprised. "We're cilsappointed that Baykeeper didn't reach out to us first for a conversation," said Kerrie Romanow, San Jose's director of environmental services. "We really think there could have been a less expensive way to start the conversation." Romanow noted that the city is geographically large. "San Jose is 180 square miles," she Bald. "You would expect that we would have more episodes than a 3 -square -mile city." CFrtfoe i OF 2 .27 of 44 Advertisement Romanow said sewage spills have been declining In recent years, from roughly 200 in 2009 to about 135 last year within city limits. This year San Jose is on pace for fewer than 100, she said. Baykeeper officials say that's still too many. They noted that San Jose's own records show it spilled 523,265 gallons of sewage from 2009 through July of this year, enough to fill roughly 20 backyard swimming pools. Much of that sewage runs into storm drains or creeks, where it pollutes the water and flows to San Francisco Bay. San Jose has more than 2,100 miles of sewage pipes connecting to its wastewater plant in Alviso. Roughly 90 percent of those pipes are made of clay, which can crack over time, causing spills or allowing water to rush in during rainstorms, causing sewage to overflow through manhole covers. The city also has more than 1,000 miles of storm drains, which empty into creeks and the bay. Baykeeper also said the city has not done enough under its federal stormwater permit to reduce trash that flows Into creeks and the bay. Romanow said San Jose has already installed nine catch basins -- large underground vaults that can cost up to $500,000 each with strainers to catch trash -- in its storm drain system, and it plans to put in 20 more over the next three years. She said the city has increased street sweeping and banned plastic bags to further reduce litter. "Our city has demonstrated commitment and intent. We are putting a lot of money and effort into this," she said. Choksi said the city has not adequately spelled out how it intends to reduce trash pollution into creeks 70 percent by 2017, as a 2009 regulation requires. Any agreement between the two parties, or a judgment In a lawsuit, could also affect homeless encampments, which are sources of trash and human waste. "This is a very good thing. it's about time that it was done," said Mondy Lariz, a longtime San Jose creek activist. Lariz said although the city has taken some steps, it hasn't been enough. "The health hazard from the homeless using the creeks as a restroom is a major problem," he said. "And the trash issue is large. Some of it is toxic materials — paint cans, hazardous waste." The Clean Water Act is one of the strongest environmental laws in the United States. It allows citizens, rather than just government agencies, to file lawsuits against polluters. Under the law, violators are subject to fines of up to $37,500 a day, meaning San Jose could technically face millions in penalties, although in many cases, settlements are worked out to reduce pollution instead. Baykeeper issued a 60 -day notice Monday that it intends to sue, which is required under the law Over the past decade or so, the group has taken legal action against about 20 cities in the Bay Area. in 2006, for example, after the city of Richmond spilled 17 million gallons of sewage over a three-year period, much of it into streams and the bay, Baykeeper filed suit and Richmond and its wastewater management agency, West County Wastewater District, agreed to spend $25 million upgrading its sewage system. In May, two environmental groups, the Natural Resources Defense Council and Los Angeles Waterkeeper, won a six-year lawsuit that went to the U.S. Supreme Court in which Los Angeles County was found liable for untreated stormwater pollution. The ruling, also based on the Clean Water Act, requires the county to clean up stormwater pollution, billions of gallons of which flows to beaches every year, sometimes causing people to become ill.

Dear Sirs, I would like to suggest that a stormwater trach and sediment removal device be installed on the storm sewer lines leading out from "The Hills at Vallco." The soil on the green roof is potentially erodible into Calabasas Creek, as well as litter going down the catch basins. It will also help the City of Cupertino fulfill the EPA's "Clean Water Act." This Act is part of a NPDES permit, and let me be clear that I believe that Cupertino is in compliance. An example of a stormwater treatment device is the "CDS hydrodynamic separator" by Centeches. Many of these have been installed by the City of San Jose. A hydrodynamic separator can be installed in place of a planned Manhole. The cost of installing on proactively would be less than installing one in reactively. In November, 2014, the City of San Jose had to build and act reactively when Baykeeper intended to sue under the Clean Water Act. In conclusion, being proactive on notjust "The Hills at Vallco," but all the developments affecting the stormwater system in the City of Cupertino will make it a great place to live for future generations. Ray Martin Attachments: EPA Sheets Contech Sheets Baykeeper lawsuit sheets Example of San Jose Plans Utility Plans 46TER 2 Of 2 ror7 THE NUMBERS: WHY THE COUNCIL MUST VOTE NO ON THE HILLS AT VALLCO Dear Councilmember, This letter is to present the Council with compelling traffic and greenhouse gas impact numbers, CEQA job -housing imbalance lawsuit exposure and significant revitalization failure risks that demand the Council disapprove rezoning VaIlco for the proposed Hills at VaIlco office build; and place a moratorium on all rezoning within the city that increases office space. The 2M sf of office build proposed for The Hills at VaIlco will increase the total number of employees who work in Cupertino and commute from other cities to over 47,000, nearly doubling the population of Cupertino every work day and making Cupertino's growth imbalance one of the primary causes of traffic congestion, transportation infrastructure cost and air pollution in the Bay Area. The exhaust from these commuter's vehicles alone will produce 700 tons of CO2 greenhouse gas daily. 20,000 new commute vehicles will converge on Wolfe Rd. from Apple Campus 2 and the Hills at ValIco office space, alone. The Hwy 280 interchange at Wolfe even when doubled in ramp lanes will only be capable of handling I400 to 3600 of these vehicles per hour during commute hours, meaning the vast majority of the new commute traffic will be directed into the neighborhoods of Cupertino and Sunnyvale. The severe nature of this is owing to the unnecessary office build at the Hills at Vallco. Adjusting the General Plan to accommodate the Hills office build and its 10,000 new office jobs without a counter -balancing increase in housing exposes Cupertino to the same court mandated job -housing balance imposed on the City of San Jose's General Plan Amendment this year, where the court mandated one home for each office space job created. Given the enormous office build at Apple Campus 2, any mixed use revitalization of Vallco should be retail - residential only not retail -office and be incented to housing Cupertino -based employees, particularly at Apple Campus 2, to reduce traffic congestion in the city. I am proposing a method to accomplish this. TRAFFIC NUMBERS — IMPACT OF 2M SF OF OFFICE SPACE The proposed Empire State Building equivalent OFFICE SPACE FOR THE HILLS AT VALLCO WILL LIKELY ADD 10,000 OR MORE COMMUTE VEHICLES TO WOLFE RD. This is based on the Silicon Valley standard 200 sf (square feet) and one commute vehicle per employee. The Empire State Building (2. I M sf) is the second largest office building in the U.S. following the Pentagon. It houses I000 businesses collectively employing 23,000 workers'. To visualize the traffic impact, note that 10,000 commute vehicles parked in two lanes of Hwy 280 with 5 feet gridlock spacing extends 20 miles on its own (one car each lane every 21 feet), the distance between Wolfe Rd. and Crystal Springs Reservoir. Add another 10,000 commute vehicles from the adjacent new Apple Campus 2 and the two-lane congestion doubles to 40 miles, the distance from Wolfe Rd. to San Francisco. THIS 40 MILES IN TWO LANES OF NEW COMMUTER VEHICLES WILL ENTER AND DEPART THE CITY OF CUPERTINO AT WOLFE RD. DURING COMMUTE HOURS EVERY WORK DAY, ABHORRENTLY ADDING TO THE TRAFFIC CONGESTION THAT ALREADY EXISTS. The Hwy 280 interchange at Wolfe Rd. is woefully incapable of handling the added commuters, even if onramps are doubled from one to two lanes. The State of California sets its metering lights to allow 350-900 vehicles per hour to enter a freeway per onramp lane 2. The rate depends on freeway traffic congestion. Assuming the state expands the onramps in each direction to two lanes, the Wolfe Rd. interchange will only be capable of releasing 1400 to 3600 vehicles per hour onto Hwy 280 when metering lights are on. Apple Campus 2 will need all of this to handle its 10,000 vehicles over the 4 — 7 pm commute period, excluding all other existing traffic and eventual new traffic from LE SER 2 OF 2 2 OF 7 Main Street and Vallco retail. ADDING 10,000 COMMUTE VEHICLES FROM THE PROPOSED HILLS AT VALLCO OFFICE SPACE WILL REQUIRE 5.5 — 14 HOURS TO VACATE THE PARKING LOTS OF JUST THE APPLE CAMPUS 2 AND HILLS AT VALLCO OFFICES ONTO THE FREEWAY ALONE DEPENDING ON METERING. Obviously, this isn't going to happen. THE BULK OF THE 40 MILES OF TWO-LANE NEW COMMUTE VEHICLES WILL BE DISTRIBUTED THROUGH THE STREETS OF CUPERTINO AND SUNNYVALE, CONSUMING AND GRIDLOCKING EVERY NEIGHBORHOOD THROUGHWAY AS COMMUTERS SEEK FASTEST COMMUTE ROUTES. The increased congestion on Stevens Creek Blvd., De Anza Blvd. and Homestead Rd. in concert with the doubling of traffic flow entering the 280 onramp lanes at Wolfe Rd. will certainly back southbound Hwy 280 traffic from the current backup point near the Hwy 85 interchange into Los Altos Hills on the southbound home commute. THIS WILL MAKE FOOTHILL EXPRESSWAY THE NEW LOGICAL FIRST FREEWAY RELIEF POINT OFF -RAMP FOR SARATOGA, LOS GATOS AND CAMPBELL COMMUTERS, as the currently free right-hand exit -only lane leading to De Anza Blvd on 280, will be fully immersed in the extended 280 congestion zone. THIS WILL CONGEST FOR THE FIRST TIME STEVENS CANYON RD. AND THROUGH STREETS SUCH AS MCCLELLAN RD, BUBB RD., LINDA VISTA DR., HYANNISPORT DR., SANTA TERESA AVE, WILKENSON AVE, COLUMBUS AVE, TERRACE DR., REGNART RD., MONROVIA AND BYRNE AVE IN THE WEST OF BUBB NEIGHBORHOOD. MASS TRANSIT — NOT A MITIGATING FACTOR The fully decentralized, fully suburban and vast area in which Silicon Valley homes and workplaces are located make mass transit a non -factor in fighting traffic congestion. THE SOUTH BAY'S LIGHT RAIL AND BUS MASS TRANSIT SYSTEMS OPERATE VIRTUALLY EMPTY BECAUSE THEY PROVIDE NO FIRST MILE / LAST MILE COMMUTE SOLUTION FOR THE VAST MAJORITY OF COMMUTERS. It is inconceivable that such a system could have stops within three blocks of both homes and workplaces for enough commuters to have a measureable impact on traffic. Such mass transit is only feasible for highly urbanized cities such as San Francisco. THERE IS NO FEASIBLE MASS TRANSIT ALTERNATIVE TO MITIGATE THE TRAFFIC CONGESTION PRODUCED BY THE PROPOSED OFFICE SPACE BUILD AT THE HILLS AT VALLCO. Sand Hill's mention of shuttles and VTA traffic mitigation is simply placatory for a problem that has not been addressed and is insolvable through mass transit. ENVIRONMENTAL IMPACT — CEQA AND ABAG EXPOSURE BY VIRTUALLY ANY STATE OR REGIONAL ENVIRONMENTAL METRIC, THE CITY OF CUPERTINO SHOULD NOT BE AUTHORIZING ANY REZONE TO OFFICE SPACE, NOW OR INTO THE FORESEEABLE FUTURE. THE COMPLETION OF APPLE'S CAMPUS 2 WILL PUT CUPERTINO'S JOBS - HOUSING RATIO COMPLETELY OUT OF BALANCE. Of the 31,800 people employed in Cupertino only 5100 live here', meaning 84% OF CUPERTINO'S WORKFORCE, 26,700 EMPLOYEES, COMMUTE HERE EVERY WORK DAY FROM OTHER CITIES. IN CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA) AND ABAG TERMS, CUPERTINO'S GROWTH IMBALANCE IN OFFICE DEVELOPMENT IS A MAJOR CAUSE OF THE COUNTY'S TRAFFIC CONGESTION, TRANSPORTATION INFRASTRUCTURE COSTS AND AIR POLLUTION. With the projected growth of 14,600 Apple employees AT THE COMPLETION OF CAMPUS 2, CUPERTINO JOBS GROWTH WILL SOAR TO NEARLY 46% OVER A 2-3 YEAR PERIOD DURING A PROTRACTED PERIOD WHEN CUPERTINO HOUSING IS GROWING ONLY 1.4% ANNUALLY'. Using the same statistics Cupertino -based employees commuting from other cities at that time will reach at least 39,000. THE PROPOSED OFFICE SPACE AT THE HILLS AT VALLCO IS EQUIVALENT TO NEARLY A QUARTER OF ALL OF THE OFFICE SPACE IN THE ENTIRETY OF DOWNTOWN SAN JOSE°. If the 2M sf Hills At VaIIco office space is approved and using the 84% statistic, THE NUMBER OF CUPERTINO-BASED EMPLOYEES FROM EXISTING, APPLE CAMPUS 2 AND HILLS AT VALLCO OFFICES COMMUTING FROM OTHER CITIES INTO CUPERTINO EACH WORK DAY WOULD BE EXPECTED TO EXCEED arfei: 2 eF 2 3 OF T 47,000, A FLAGRANT CEQA AND ABAG IMBALANCE. IF WE PARKED THAT NUMBER OF VEHICLES ON HWY 280 IN TWO LANES, AS IF THOSE COMMUTING FROM OTHER CITIES WERE WAITING AT A GATE TO ENTER CUPERTINO EACH MORNING, THE VEHICLE BACK-UP WOULD EXTEND 94 MILES, THE DISTANCE FROM WOLFE RD. TO ROUGHLY SANTA ROSA! Assuming an average roundtrip commute of 25 miles and a standard 1.22 lbs CO2 emissions per miles, THE TOTAL CO2 EMISSIONS FROM THOSE CUPERTINO-BASED EMPLOYEES COMMUTING FROM OTHER CITIES WILL BE OVER 700 TONS DAILY, 150 TONS DUE TO THE APPROVAL OF THE HILLS OFFICE SPACE ALONE. CCEC V. CITY OF SAN JOSE AND ITS GENERAL PLAN — JOBS -HOUSING IMBALANCE LAWSUIT The City of Cupertino cannot afford to ignore the environmental impact and job -housing imbalance issues incurred in the community and region by its General Plan and its development projects. In April of this year, a CEQA suit by the California Clean Energy Committee against the City of San Jose successfully over -turned its General Plan for failing to address the jobs -housing imbalance of its planned office space development. THE COURT FAULTED SAN JOSE FOR NOT PLANNING ENOUGH HOUSING TO ACCOMMODATE THE JOBS CREATED BY ITS GENERAL PLAN, PUSHING HOUSING AND TRAFFIC INTO OTHER COMMUNITIES TO ACCOMMODATE THOSE JOBS. THE COURT ORDERED SAN JOSE TO INCREASE ITS HOUSING UNIT ALLOCATION BY THE ENTIRE JOBS -HOUSING IMBALANCE SHORTFALL (I09,000 HOMES) AND TO PAY THE ENTIRETY OF THE $300,000 SUIT LEGAL COSTS6'7. The proposed Hills At Vallco project and accommodating Cupertino General Plan Amendment exposes Cupertino to the same jeopardy. The city of Cupertino, its schools, infrastructure and lack of available land cannot accommodate the housing needed for the jobs that will be created by the Hills at VaIIco, let alone Apple Campus 2. Environmental advocacy groups, such as the California Clean Energy Committee, make it their business to discover and force city jobs -housing balance to minimize regional traffic and pollution. It is inconceivable that the highly publicized and massive office build of the Apple Spaceship campus and The Hills At Vallco proposal I General Plan Amendment are not on the radar screen of these advocacy groups. ENVIRONMENTAL IMPACT— IS CUPERTINO WORKING ON THE WRONG ISSUES? THE MOST IMPORTANT TRAFFIC MITIGATING ENVIRONMENTAL IMPACT STATISTIC FOR CUPERTINO IS THE PERCENT OF ITS RESIDENTS WHO WORK IN CUPERTINO. If affordable housing and rents were the primary determinants then one would expect a reasonable number of highly paid engineering professionals at Apple to live here, at least rent. The fact is only 10% do, the same as live 40 miles away in San Francisco8. Obviously, other factors play an important role for where people hired in Cupertino opt to Iive. Cupertino has long been a one -trick pony community that's main attraction is its excellent schools. Outside of the schools, Cupertino has very few standout features and several significant deficits, most importantly no downtown and the total Iack of a social environment for the singles and millennials that compose the majority of the Apple and new Silicon Valley workforce. The significant disconnect between the demographics and lifestyle needs of the workforce of Cupertino, its residents and city offerings is certainly a major reason why Cupertino -based employees choose not to live here. VALLCO STANDS AS THE LAST HOPE FOR CUPERTINO TO CORRECT THIS PROBLEM. IDEALLY, THE REVITALIZATION OF VALLCO SHOULD BE CENTERED ON ATTRACTING THE YOUNGER GENERATION OF SINGLES AND MILLENNIALS WHO WORK HERE WITH THE BEST AND MOST ABUNDANT IN VALLEY OFFERING OF TRENDY AND FULLY ONLINE RESTAURANTS, COFFEE SHOPS, NIGHTCLUBS, SOCIAL MEETING POINTS, RETAIL SHOPS AND ENTERTAINMENT WITH COORDINATED URBAN HOUSING DESIGNED SPECIFICALLY FOR AND EQUALLY ATTRACTIVE TO THE TECHNOLOGY, ACTIVITIES AND LIFESTYLES OF THIS GENERATION... THE MOST COVETED PLACE TO LIVE (AND WALK TO WORK) FOR YOUNG APPLE EMPLOYEES. A vibrant retail center such as this would attract a healthy clientele weeklong and over longer hours, attracting also older generations and families who prefer "happening places" for entertainment and shopping as well. SAND HILL'S Lox 2 or -1 4 DF r CURRENT PLAN TO REPLACE THE BULK OF THE RETAIL SPACE AT VALLCO WITH HIGH DENSITY OFFICE SPACE TOTALLY DEFEATS THIS POSSIBILITY AND CEMENTS, PERHAPS FOREVER, CUPERTINO'S INABILITY TO REVITALIZE THE CENTER AND INCREASE THE NUMBER OF ITS RESIDENTS WHO WORK HERE. RISKS THAT OFFICE BUILD WILL PREVENT REVITALIZATION OF VALLCO The risk factors against a successful revitalization of Vallco through the proposed Hills at Vallco development are extensive, obvious and underscore Sand Hill's inexperience in building and managing such a project. First, there is HIGH RISK THAT BOTH SHOPPERS AND RETAILERS WILL FIND THE HILLS AT VALLCO UNATTRACTIVE DUE TO VASTLY REDUCED RETAIL EMPHASIS (NO LONGER "DESTINATION RETAIL CENTER"), INCUMBERED ACCESS DUE TO HEAVY TRAFFIC CONGESTION AND EXCESSIVE MIXED USE COMPETITION FOR PARKING. These risks are underscored in the letter sent October 9, 2014 to Paul Brophy, Cupertino PIanning Commission, by Sears' attorney Ivor Samson in which Sears analysis of the Hills at Vallco proposal forecast lower Sears revenue due to these factors9. Indeed, the proposed Hills retail space (discounting that allocated for concert area, public areas and innovation center) is far less than half of the current Vallco retail, and LESS THAN A QUARTER OF THE RETAIL SPACE OF ITS REGIONAL COMPETITOR AT WESTFIELD VALLEY FAIR10'" -''-. THE HILLS AT VALLCO IS NOT A `REVITALIZATION OF VALLCO' AS A RETAIL CENTER BUT A TRANSFORMATION TO AN ENORMOUS OFFICE COMPLEX MATCHING IN OFFICE SPACE THE ENTIRE RETAIL SPACE OF VALLEY FAIR, BOTH 2M SF. Shared parking is a significant and well documented risk for failure of mixed use developments and the risk at The HiIIs is particularly onerous. THE 10,000 HILLS OF VALLCO OFFICE WORKER VEHICLES REQUIRE MORE PARKING SPACES THAN THE ENTIRETY OF THE WESTFIELD VALLEY FAIR MALL, INCLUDING THE NEW FIVE STORY PARKING STRUCTURE CURRENTLY UNDER CONSTRUCTION. THERE IS MAJOR RISK THAT COMPETITION FOR CONVENIENT, QUICKLY FOUND PARKING SPACE WILL DETRIMENTALLY FRUSTRATE THE HILLS AT VALLCO SHOPPERS. Assuredly, many of the retail parking spaces will be more convenient to office workers than the least convenient multi -story office parking spaces, assuming they are separated and designated as such. IT IS INCONCEIVABLE THAT RETAIL SHOPPERS WILL BE GATE -CHECKED OR GIVEN A PASS TO ENTER ANY RETAIL SHOPPING PARKING AREA TO DISTINGUISH THEM FROM OFFICE WORKERS WHO WILL TAKE THE MAJORITY OF HILLS PARKING SPOTS ON WEEKDAYS PRIOR TO THE OPENING OF MOST RETAIL SHOPS. THERE IS SIGNIFICANT RISK, THEREFORE, THAT WEEKDAY SHOPPERS WILL SUFFER CHRISTMAS -LIKE PARKING FRUSTRATION THROUGHOUT THE YEAR AT THE HILLS BECAUSE OF THE CO -EXISTENCE WITH 2M SF OF OFFICE SPACE. THIS ASSUREDLY WILL DECREASE RETAIL TRAFFIC AND POTENTIALLY DOOM THE RETAIL REVITALIZATION OF THE SITE. Sand Hill Properties has no experience in building or maintaining the environmentally attractive 30 acre green toupee of The HiIIs at Vallco. Park maintenance will be a very expensive, budget -draining proposition. A small army of fuII-time gardeners, landscapers, arborists and other specialists must be employed year around to maintain the nearly 23 football fields of meadows, vineyards, orchards, organic gardens, children's play areas, walking and jogging trails promoted by Sand Hill. There is foreseeable risk that crew cutbacks during any challenging economic time would convert this centerpiece of the project to the area's greatest elevated eyesore. There is risk also that office businesses wiII find it unattractive or unbearable to have office windows that receive no natural sunlight due to the covering. Like the senior housing scenario at Main Street, THERE IS REASONABLE RISK THAT SAND HILL PROPERTIES WILL DISCOVER A NECESSITY TO DROP THE SIGNATURE PARK -LIKE COVERING OF THE HILLS EXPOSING THE UNATTRACTIVE 2M SF OF HIGH DENSITY OFFICE AND ITS PARKING STRUCTURES THAT LIE BENEATH. LEITE,p 2 DF 2 ,-1 OF r A final risk is funding. BANKS CONSIDER MIXED USE DEVELOPMENTS RISKY for aII of the reasons stated above. And THIS DEVELOPMENT IS MORE COMPLEX AND RISKY THAN MOST MIXED USE DEVELOPMENTS. When retail, office and residential units go vacant developers have trouble making loan payments. THERE 1S REASONABLE RISK THAT SAND HILL PROPERTIES WILL NOT BE ABLE TO SECURE THE ENORMOUS LOAN REQUIRED TO CONSTRUCT THE HILLS AT VALLCO AS PROPOSED, ESPECIALLY GIVEN THE MAJOR ISSUES INTRODUCED BY THE ENORMOUS OFFICE SPACE COMPONENT, TRAFFIC, SHARED PARKING AND CONSEQUENT RETAIL SURVIVAL RISKS. SAND HILL'S DECEPTIVE MARKETING AND POLLING Sand Hill Properties has undertaken a significant and highly deceptive marketing campaign aimed at getting the bulk of Cupertino residents to submit written postcard mail -in support for the project. Undoubtedly, a statistic will be presented to the Council by Sand HiII showing vast resident support when the critical vote for rezoning is taken. The problem is that Sand Hill has not disclosed in its very seductive mailers, Hills at Vallco website and town meetings the fact that the bulk of Vallco revitalization, 2M sf, will be office space filled with 10,000 employees who will commute to Cupertino every work day. Such disclosure, of course, would kill the project by triggering a whole set of resident concerns including marginalization of the new shopping center, abhorrent traffic, added housing requirement and their collective impact on schools. Within my network, residents who've discovered the omission are furious over the deception, especialIy after having given their written support of the project. Any resident approval statistic submitted by Sand Hill Properties should be dismissed by the Council. WHY DEVELOPER'S PUSH OFFICE SPACE IN CUPERTINO— CITY OF PALO ALTO MORATORIUM Why are we seeing so many developer proposals to rezone Cupertino retail to office space (Vallco, The Oaks)? CUPERTINO IS A MAJOR DEVELOPER TARGET IN SANTA CLARA VALLEY FOR CONVERSION DUE TO THE WINDFALL ANOMALY THAT OFFICE LEASE RATES HERE ARE NOW OVER 40% HIGHER THAN RETAIL LEASE RATES AND 40% HIGHER THAN OFFICE, RETAIL AND RESIDENTIAL LEASE RATES IN GENERAL IN SANTA CLARA VALLEY13. The current office Iease rate in Cupertino is $42.90 /sf/yr and skyrocketing at +24.3% annuaIIy, while the lease rate for retail is $30.20/sf/yr and growing at less than half the office rate. The county average Iease rate is about $30 /sf/yr for both retail and office space. The applicable square footage is multiplied through multi -story office construction, making it far more profitable than single street level retail. THIS BRINGS SAND HILL PROPERTIES' MULTI -STORY OFFICE CENTRIC `REVITALIZATION' DESIGN FOR VALLCO, ITS UNADDRESSED TRAFFIC AND ENVIRONMENTAL IMPACT PLANNING, ITS OFFER TO BUILD A FREE -TO -THE -CITY SCHOOL AND INNOVATION CENTER IN EXCHANGE FOR REZONING, IT'S EXPENSIVE AND DECEPTIVE MARKETING AND SURVEY CAMPAIGN INTO TOTAL FOCUS. SAND HILL'S REVENUE FROM JUST OFFICE SPACE LEASING AT THE HILLS ALONE SHOULD EXCEED $IOOM ANNUALLY, MUCH MORE THAN IF `REVITALIZED' TO THE INTENDED SHOPPING CENTER. The mission of a company is to be maximally profitable and THE HILLS AT VALLCO IS EXACTLY WHAT ONE MIGHT EXPECT FROM A DEVELOPMENT COMPANY DOING THE DESIGN. Faced with similar growth and traffic issues and loss of retail space, the City of Palo AIto passed an emergency ordinance in May prohibiting the rezoning of ground -floor retail space into office. The move was made to preserve the City's "slow -growth residential philosophy" and "protect its resident's health, safety and welfare" 14. A similar philosophy and action is desperately needed in Cupertino. LE77ER 2 OF2 & OF r A BETTER APPROACH TO VALLCO REVITALIZATION In my opinion, the revitalization of VaIIco should include two critical elements: First, an innovative, game change shopping destination sustainably competitive with Valley Fair, other regional successful shopping centers and downtowns; and second, integrated urban residential units designed, structured, regulated and incented to house within easy walking distance or inter -city shuttle the millennial and subsequent generations of Apple and other Cupertino -based employees who work at Campus 2, other Apple and Cupertino employee campuses. This design approach provides several most important city benefits. First, it CREATES THE `REVITALIZED' VALLCO THAT RESIDENTS DESIRE. Second, it REDUCES COMMUTER TRAFFIC AND CARBON FOOTPRINT within Cupertino and the Bay Area. Third, the residential units and total lack of included office space will REDUCE ABAG, CEQA AND OTHER ENVIRONMENTAL ADVOCY GROUP PRESSURE FOR MORE HOUSING AND ITS CONSEQENT EFFECT ON SCHOOLS AND TRAFFIC. Fifth, regulated to omit children, the residential element will have ZERO IMPACT ON SCHOOLS. Sixth, the high density residential units will provide an ATTRACTIVE PROFIT COMPONENT FOR THE DEVELOPER AND REZONE LEVERAGE FOR THE CITY TO MAKE SURE THE DESIGN IS DONE TO MEET THE NEEDS OF THE CITY AND ITS RESIDENTS. The retail component should first include favorable numbers, quality and types of shops, including anchor stores Iike Macy's, and attractive ambience to create a "shopping destination" sustainably competitive to its primary competitor at Valley Fair. For the single and millennial generation, the mix should also include trendy restaurants, best in area sports bars and night clubs with evening bands and entertainment, theatres, sports stores, coffee shops and mobile centric eateries that provide nutritional, good value meals that can be ordered and paid ahead via mobile device by the young "don't -want -to -cook" residents for pick up on the walk home from work. A game change addition would include complete mobile device connection with every shopper, providing such things a locations of available parking, directions from current location to specific shops, shop search for desired retail items, shop information, sales and mobile coupons, mobile food and item ordering, show times and ticket ordering... all available on a center -specific mobile ap that fully enriches the shopping experience. The center should contain Apple's flagship store, due to its next door location to the Apple Spaceship HQ. The mix of extensive retail and urban millennial housing provides a most attractive business environment with far fewer risk factors for attracting and retaining the best and most popular retailers. The design of the residential component needs to be prioritized on two basic elements: first, its unparaIIeled appeal to young single and millennial Cupertino -based employees and, second, its full access integration with the retail center. Features should include built-in and upgradable mobile device home functionality, built-in secure Wi-Fi, wall -mounted flat panel TV, gas insert fireplace, in -suite dining and entertainment areas and street level bicycle Iockers. Rents for Cupertino -based employees should be discounted and include perks like free or discount gym membership within the center. Some units should be furnished to attract new college hires. In this scenario, the Apple Spaceship HQ and adjacent revitalized VaIlco center will highlight the innovation of Cupertino, both in technology and green growth solutions. 1 encourage the City of Cupertino to vote against rezoning ValIco and thereby disapprove of the proposed mixed retail -office Hills at Vallco design. The enormous office component is unnecessary, will only benefit the developer, will force enormous detrimental traffic impact on the city and neighboring communities and expose the City of Cupertino to potential CEQA litigation over gross jobs -housing imbalance. THE COUNCIL SHOULD KEEP IN MIND THAT WHILE AN AVERAGE CUPERTINO RESIDENT MAY BENEFIT FROM THE HILLS AT VALLCO REVITALIZATION TWO OR THREE TIMES PER MONTH ITS OFFICE SPACE WILL SUBJECT EACH RESIDENT TO DEBILITATING TRAFFIC EVERY DAY. An alternative retail -residential mixed use approach as outlined above is far better for Vallco revitalization. It offers far less risky development that lowers LE17F.R 2 DF 2 70F7 traffic congestion and the City's jobs -housing exposure. In short, the City should send Sand Hill Properties back to the drawing board.
