|
|
| | | | | | | | | Present Situation | Runoff from the plateau area adjacent to the northern end of the Blandford Canyon drains untreated and undetained to the canyon storm system, which flows to a stormwater pond along Columbia House Boulevard and ultimately drains to the Columbia River. Localized flooding occurs downstream along Columbia House Boulevard upstream of the stormwater pond. This project will install 21 underground filter media cartridge units, two bioretention facilities and associated underground infiltration facilities. These new facilities will treat and infiltrate stormwater from approximately 22 acres of impervious surfaces reducing flows to the Blandford Canyon system.
On 11/28/2023, the City received 11 bids for the subject project. The bids ranged between $1,456,546 and $2,669,480. The low bidder was responsive. The bids are as follows:
