Ten Mile Creek Bridge Replacement Hydraulic Analysis

WSE, retained by Sargent Engineers, provided hydraulic design services for the replacement of an aging bridge over Ten Mile Creek in Whatcom County, WA.

Role / Services: WSE visited the site and documented existing bridge conditions. A hydraulic model was developed to assess hydraulic conditions at the existing crossing and to evaluate proposed replacement alternatives.

Outcome: Based on the hydraulic evaluation, WSE and Sargent determined a bridge span that would safely pass the 100-year design event with adequate freeboard. A bridge protection concept was also developed to protect exposed abutment slopes under the bridge. Construction is anticipated in the summer of 2017.
