body
BACKGROUND INFORMATION:
As previously discussed with the City Council, there are a number of locations around town that were heavily impacted by the recent, historic rainfall events. Over the coming years staff plans to complete a variety of storm-related projects intended to reduce the impacts of future major storms. One of the neighborhoods that is most-impacted is the Vineyard Terrace subdivision, located at the northeast corner of Century Boulevard and Lower Sacramento Road. This neighborhood has encountered street flooding even during moderate storms despite the storm drain system meeting the City's standard design criteria.
This project constructed a storm drain relief line between the subdivision's on-site system and a separate drainage system nearby that serves the Lower Sacramento Road drainage (see Exhibit A). That line has excess capacity, and this connection will reduce the likelihood of street flooding within the subdivision.
Council approved the plans, specification, advertisement, and the award authority on June 7, 2023. Bids were received on June 22, 2023, with Soracco, Inc. being the only bidder (see breakdown below). The contractor started work on August 18, 2023, and completed the work on October 16, 2023. The contract was completed in substantial conformance with the specifications approved by City Council. The final contract price was $156,111.00, which is $1,520 less than the original contract price due to a slight reduction in pavement rehabilitation area.
