capacity for the proposed increment of de�eiopment's peak wastewater flow rate. If an inadequacy is found and the proposed increment of developmertt represents th� entire cause of the ca�acity shortFall, the applicant shall bear full responsibility far ft�nding the required impravements to FOSMD's system; if the proposed increment of development does not repr�sent the er�tire cause of such an it�capacity, the applicar�t shall pay its fair share o# the cost of such impro�ements. Finding: Implementation of Mitigatian 10-2 in accardance with the policies and standards of the FOSMD Master Plan would reduce the identified wastewater collectian system capacity impact to a less-tha�-signifrcant level. Facts in Support of Finding: �mplem�ntatian af Mitigatior� 90-2 would reduce the project impact on wastewater collection system capacity to a less-than-sign�cant le�el thraugh a collaborative effort between tf�e applicant's engineer, Fair Oaks Sewer Maintenance District (FOSMD), and San Mateo County Engineering Department in accordance with the FOSMD Master Pfan. These facts are described and quantified in Draft EIR chapter 10 (Utilitiesj, section 10.2 {Wastewater}, on pages 10-16 through 10-22, and appendix 21.5 (Supplemental Public Utilities Informatian), which are hereby incarporated by reference. Impact: Impact 10-3: Increased REsk of Flooding Resulting fram Loss of Existing DeteRtion 5torage. The project de�elopment site would be substantially recanfigured, with replacement of all exis#ing buildings and elimination af a large part of the existing at-grade parking. If the associated regrading and construction of new buildings reduces the existing valume of on-site detention storage, fload le�els on the project development site and elsewhere within the basin couEd rise compared to current conditions. Mitigation: Mitigation 14-3. The praject shall not increase off-site flooding compared to existing conditions. Finished grades within the porkions of the project developmen# site located outside the proposed building envelopes shall be set at an average elevation that maintains, at a minimum, the existing volume of on-site stormwater detention storage, until such time as the City's downstream discharge canstraints (e.g., Bayfront Canal) are resolved and the storage is no lor�ger needed to protect the �raject impro�ements and improved properties in the adjoining neighborhoods. Project grading requirements would be based on a detailed, design-level study prepared by the project engineer and approved by the City Building, lnfrastructure, and Tra�sportation Department. 7he study Would document the volume of storage currently available on the praject development si#e and establish proposed grades to replicat� this existing storage condition following construction of the proposed ►�ew buildings. The stormwater detention potential of the project-proposed approximately 2.4-acre publicly accessible open space and of#he project-proposed greenway shall be incorporated into the design-level study. Ir� addition, all proposed impro�ements that are not elsr►ated aba�e the 100-year flood elevation would f�ave to be flood-proofed or otherwise protec#ed from the efFects of high wat�r. The appl€can# shall develop a pragram by which future building tenants can be notified that vehicles parked within patential flaod ATTY/RE5D,2898/PC RE50 RECOMMENpING STANFQRD EIR CERTIFICATlON REV:08-15-13 VR Page a4 af 56
