Dear City Councils,

I would like to bring your attention of the letter from Cupertino Sanitary District dated on May 23, 2014. The letter is sent to the city regarding the impact on sewer system regarding the proposed GPA. 

 

Based on the number in this letter, just with the 2020 build out with the 2000-2020 General plan, we are almost at the capacity. The capacity is at 7.85mgpd while just with the build out, the city will reach 7.2mgpd. Which means that we do not have much buffer beyond the development allocation in 2000-2020 General Plan. The 2million sf office allocation at the Vallco alone will add 0.3mgpd based on 0.15gpd per square foot use in this letter for office. 

Moreover, the letter also pointed out that "it was identified that sewer mains along Stevens Creek, Blaney and Wolfe would be at near capacity or would not have sufficient capacity to accept new developments beyond the City Center Project." Basically, we do not have sewer mains to support the redevelopment of Vallco for excessive number of new offices or housing units.

At the end of the letter, the district cautioned the city to take necessary actions to ensure the sewer system can support the future development and not to be in a position that City of Milpitas was in back 2008, imposing a building moratorium.

 

I would like to urge the councils to make sure the basic infrastructure, such as sewer mains, can support the development allocations and recommend to keep the allocations in 2000-2020 General Plan unchanged.

Please put this correspondence to the public records of May 19, 2015 City Council meeting.

 

Sincerely,

Xiaowen Wang

Cupertino Resident
