HomeMy WebLinkAbout041823-06.4ADMINISTRATIVE STAFF REPORT 6.4 TO: Mayor and Town Council April 18, 2023 SUBJECT: Resolution No. 25-2023, awarding a construction contract and transferring funds from CIP No. A-330 Town -Wide Storm Drain System Management to CIP No. A-614 Westridge Trash Rack Modification BACKGROUND The Town's Capital Improvement Program includes trash rack improvements at Starview Drive, Loch Lomond Way, and Westridge Drive, CIP Nos. A-608, A-613, and A- 614 respectively. The project will mitigate impacts from sediment and debris during flood events by upgrading existing storm drainage systems. This project is funded in part by the Hazard Mitigation Grant Program (HMGP), a federal grant program administered by FEMA. DISCUSSION Five bids were received and opened on March 28, 2023. The lowest responsive bid was submitted by Ella of Alamo, California, with a bid of $747,000. Bid results are summarized in Attachment C. The Engineer's estimate was $787,130. The work is scheduled to begin in spring 2023 and be completed later in summer 2023. This project is considered a minor alteration to existing facilities and is therefore categorically exempt from the requirements of the California Environmental Quality Act (CEQA) according to Guidelines Section 15301 (Class 1). PUBLIC CONTACT Posting of the meeting agenda serves as notice to the general public. Before construction begins, residents within close proximity to the project will be notified by the contractor in writing. FISCAL IMPACT The low bid amount of $747,000, plus a 15% contingency amount of $113,000 yields a total construction budget of $860,000. A transfer from CIP No. A-330 Town -Wide Storm Drain System Management in the amount of $165,000 is needed to fully fund the project. RECOMMENDATION Adopt Resolution No. 25-2023, awarding a construction contract and transferring funds from CIP No. A-330 Town -Wide Storm Drain System Management to CIP No. A-614 Westridge Trash Rack Modification.

To prevent clogging a larger and more extensive trash rack is needed to replace the existing trash rack. The proposed trash rack will be approximately 6' wide by 20' long by 6' tall and will consist of large galvanized iron bars with approximately 10" gaps. Large debris, logs, and rocks will be filtered from the stream flow. The increased trash rack area will minimize clogging and allow for easier cleaning, both during and after the storm event. A grant for this project has been secured for Hazard Mitigation Grant Program (HMGP) funding. Construction phase anticipated fall 2022 DESCRIPTION OF MODIFICATIONS: Updated description.

Every 8 to 10 years there is a major storm event that floods the residential area. The major cause of the flooding is the inability of the storm drain system to manage the tremendous amount of debris that accumulates within the trash rack system installed by the Town. This project provides a final safety measure to capture storm water that bypasses the trash rack system during major storm events. Installation of additional catch basins on Westridge Avenue, and an additional flood control wall and inlet system can prevent future flooding. A grant for this project has been secured for Hazard Mitigation Grant Program (HMGP) funding. Construction phase anticipated fall 2022. DESCRIPTION OF MODIFICATIONS: Updated description.
