BACKGROUND Sewers The City’s Master plan of Sewers, prepared in 2002, identified several deficiencies in the City’s sewer system and recommended upgrades. Improvement areas for years one and two were selected for enhancement at the following locations: 1. Enid Avenue, from Gladstone to Grandview, 780’ 2. Calera from Mauna Loa to Holleyvale, 640’ 3. Azusa Alley (the alley between Azusa and San Gabriel), from First to Foothill, 5100’ The existing lines are 8 inches in diameter and the Master plan recommended increased pipe sizes. The new pipes will be 15 inches (except for a section of the Azusa Alley, which will be 18 inches for about 3200 feet). As part of the sewer upgrades, the streets will be completely resurfaced with an asphalt concrete overlay and the alleyways re-constructed. Storm Drain Improvement on Soldano Avenue The surface run-off water on Soldano Avenue has, for years, sheet-flowed over the County facility adjacent to the Little Dalton Wash and into the channel. The constant flow of water has begun undermining the Wash walls and needed to be re-directed. To protect the structural integrity of the Little Dalton Wash, the surface water will be collected in two catch basins and conveyed, via a pipe, into the channel directly. Plans have been prepared to install the two catch basins and we have already received a construction permit from the County to begin the construction phase. The estimate for the storm drain improvement is $48,000. Both sewer and storm drain projects have been combined in order to potentially realize cost savings in contractor mobilization. FISCAL IMPACT While only phase one of the sewer project was funded in the current fiscal year, the design was completed for projects in years 1 and 2, both. There is a request in the upcoming year’s budget for year two sewer upgrades in the amount of $555,000. This project will be advertised in one package for years one and two. In case additional sewer funds are not secured for the year two projects, the unfounded portion of the project will be deferred. Engineer’s estimate for the total project cost is $1,200,000 from the following sources: 348-0000-665-7145-66503A $631,000 [FY2002-03, funded] Sewer fund request for FY03-04 $555,000 [FY2003-04, requested] 348-0000-665-7145-66501A $ 52,000 [FY2002-03, funded] Total $1,238,000 Attachments: Plans and specifications
