STAFF REPORT

Agenda Item #3.Meeting Date: March 22, 2021

Discussion ItemTo: ENGINEERING AND OPERATIONS COMMITTEE From: Operations Manager

Subject: Lillian Sewer Main Project

RECOMMENDATION:

This report is provided to the Engineering and Operations Committee for its information only.

BACKGROUND / ANALYSIS:

During the development of the fiscal year 2020-21 budget, the wastewater camera crew identified two segmentsof sewer main in need of repair due to cracks in the pipe. The first was 650 linear feet on Lillian Lane south ofBaseline Street through 11th Street north of 10th Street and the second approximately 390 feet on 11th Street eastof Cole Ave and west of Palm Ave. The current budget describes these two streets as one project.

Knowing that the sewer mains have cracks it is normal practice to periodically go back and make sure the crackshave not increased in size. Unfortunately, crews have found more cracks on Lillian Lane and now recommend1270 feet of pipe to be replaced this fiscal year. Due to the increased footage of pipe in need of replacement staffrecommends making Lillian Lane and 11th Street two separate projects. Current fiscal year addressing LillianLane and next fiscal year make 11th Street a new project. 11th Street will be reevaluated with a new updatedfootage for replacement in fiscal year 2021-22.

The District has a proactive pipeline video monitoring program to inspect sewer mains to help prioritize this CIPproject. This program identified approximately 1,270 lineal feet of 6-inch VCP sewer pipe on Lillian Lane justsouth of Baseline Street to 10th Street with cracks in the pipe. The job will be to remove the existing sewer pipeand replace with new.

Staff issued a Request for Bids to three Contractors and two bids were received during December 2020.Unfortunately, one contractor was unable to provide a quote for the job due to staff sick with Covid-19. Thelowest responsive bid for the construction was received from TK Construction for $231,820.

The recommendation for repairs on Lillian Lane will be present to the Board of Directors in April 2021.
