Post Falls Police Department Parking Lot Expansion Bids Open April 7
Post Falls opened bids Monday on a police parking lot expansion that will capture all stormwater on-site, waiving a general permit typically required for sites over one acre.
The Post Falls Police Department's planned parking lot expansion will handle all stormwater on-site without triggering the state general permit that typically applies to construction projects of its size, under technical clarifications the city published March 31 ahead of Monday's 2:00 p.m. bid opening.
Despite the project site exceeding one acre, the city determined that neither a Construction General Permit nor a Stormwater Pollution Prevention Plan is required. The design captures and infiltrates all runoff on-site, with no discharge reaching Waters of the United States. Contractors are directed to follow Best Management Practices for erosion and runoff control under a special provision included in Addendum No. 1, rather than the more formal permitting process that larger disturbed-area projects often require.
On pavement, the clarifications specify that Hot Mix Asphalt sections must be compacted to 92% of the maximum theoretical density. Bidders were directed to the geotechnical report in Appendix B of the project manual for subgrade recommendations. HMH Engineering, the project's engineering firm, flagged a potential wrinkle on the south portion of the lot: once clearing and initial grading begin, the team may recommend a pavement design reevaluation if in-place soils prove firm and contain minimal fine-grained silt. Bid quantities were estimated using a consistent pavement section across the full site, subject to revision depending on what crews find in the ground.
Gate and keypad work carries its own defined scope. The contractor is responsible for the keypad foundation and entrance conduit following Solid Rock Automation specifications in Part 6 of the project manual. Two safety bollards must be installed around the north entrance keypad, positioned so they do not impede vehicle access, with owner approval required on product and placement before ordering or installation. A Gate and Keypad Exhibit was distributed with Addendum No. 1 alongside modified bid schedule items.
One procedural detail contractors had to account for: HMH Engineering is not providing on-site quality-control services for the project, meaning firms were expected to bring their own QC plans to the table.
With bids now submitted, the city will review proposals and move toward contractor selection pending procurement and funding approvals.
