BACKGROUND The Small Drainage Program constructs drainage projects throughout the City that are too large for City staff to complete but are smaller than a typical capital improvement project. The projects originate from citizen complaints and maintenance staff recommendations and are compiled on the Small Drainage Project List. Each year the projects are prioritized based on need, expense, permitting requirements, and length of time on the list. The highest priority projects are then designed and constructed. The 2025 Annual Small Drainage Program includes three locations as noted in the attached vicinity map and will improve roadside drainage conveyance and water quality improvements at the 40th Ave S/42nd Ave S location. DISCUSSION The 2025 Annual Small Drainage Program was advertised for bids on July 30 and August 6, 2025. Five bids were received and opened on August 14, 2025. The bids were checked, tabulated, and no errors were found. Flowline, LLP, is the apparent low bidder with an overall bid of $352,692.90 including sales tax and is 15.6% below the engineer's estimate of $418,188.06. This contractor has not worked for the City before. Psomas, construction management consultant, and City staff analyzed and reviewed their bid and Psomas spoke directly with Flowline and felt comfortable moving forward. BUDGET AND BID SUMMARY (All amounts include sales tax) The project construction budget of $750,000 is sufficient to cover the costs for the contract with contingency. The project is funded through the Surface Water Enterprise Fund. Bid Results Engineer's Estimate Contract $352,692.90 $418,188.06 Contingency (10%) $35,269.29 Total $387,961.49 2025 Budget $ 750,000.00 RECOMMENDATION Council is being asked to award a construction contract to Flowline, LLP, in the amount of $352,692.90 plus contingency to construct the 2025 Annual Small Drainage Program and consider this item on the Consent Agenda at the August 25, 2025 Special Council Meeting.
