1 PROJECT OVERVIEW General Project Information Project Title: Pacific Grove ASBS Storm Water Diversions to MRWPCA Project Location: City of Pacific Grove Estimated Cost: $4,000,000 Brief Project Description ( to 2 sentences): This project would entail upgrading and expanding the existing dry weather diversion system to increase the capacity of the collection system to be able to divert up to the 85th percentile wet weather storm from a portion of the City of Pacific Grove to the MRWPCA Project Proponent Information Contact Name: Thomas Frutchey, City Manager Affiliation: City of Pacific Grove Address: 300 Forest Avenue, Pacific Grove, CA Phone Number: (83) tfrutchey@ci.pg.ca.us Other participating and/or partner agencies/organizations (if applicable): MRWPCA DETAILED PROJECT INFORMATION Description Please provide a description of your project (including the location) and its purpose, what will be constructed and/or implemented, how the project will function, the area(s) and/or entities that will be affected by or will benefit from the project, and any potential obstacles to implementation. This project would entail upgrading and expanding the existing dry weather diversion system to increase the capacity of the collection system to be able to divert up to the 85th percentile wet weather storm from a portion of the City of Pacific Grove to the MRWPCA. This project would be primarily within or adjacent to the Ocean View Boulevard right-of-way from Forest Avenue east to David Avenue. Improvements would include upgrades to the City of Pacific Grove s existing dry weather urban diversion system to increase the capacity to allow the conveyance of wet weather flows in addition to dry weather flows. New pumps would be installed at Greenwood Park, Berwick Park, and Eardley Avenue pump stations. Approximately,00 feet of 4-inch and 8-inch storm drain lines connecting the Berwick pump station to Greenwood pump station to the MRWPCA would be replaced with 0- inch lines. This project would capture runoff from approximately 222 acres (23% of the total 950 acre ASBS drainage area) and convey it to the MRWPCA RTP. Connections between the stormwater collection system and the MRWPCA are proposed at the existing MRWPCA Coral Street pump station and at the Point Pinos Stormwater Treatment Facility. Expected annual volume of stormwater flow is 76 acre-feet per year. The existing dry weather diversion system is sized to convey 200 gpm to the MRWPCA, and includes five pump stations, and over 6,800 feet of conveyance pipeline. The five pump stations are located at () Lovers Point, (2) Fountain Avenue, (3) Greenwood Park, (4) Berwick Park (9th St.), and the newest installation at (5) Eardley. Flow from Lovers Point is delivered to the Fountain pump station then into the sanitary sewer system. Flow from Eardley is pumped to Berwick Park which is delivered to the pump station at Greenwood Park and into the sanitary sewer system.
