TVGA was retained by the Village of Silver Creek to provide professional survey, engineering and construction support services for the stabilization of approximately 850 LF of streambank along Walnut and Silver Creeks.  This project was funded through the Hazard Mitigation Grant Funding program of the Federal Emergency Management Agency (FEMA).

The Village of Silver Creek’s wastewater treatment plant sits adjacent to both Silver and Walnut Creeks, just upstream of their confluence with Lake Erie.  The persistent erosion from heavy stream and ice flow has caused a continuous scouring of the west bank of these streams, slowly encroaching on the wastewater treatment plant facilities.  The Village applied, and subsequently received a grant, for a streambank stabilization project that would arrest the scour action along the west bank of the streams and adjacent to their facilities.

TVGA’s scope of services included the following phases: study; design; construction support; and grant administration. TVGA conducted a study in stream geomorphology to confirm the scope of services for which the Village received grant approval. During this phase, TVGA worked with the involved environmental agencies to receive their concurrence on the design approach, which included a combination of hardened protection and “green” solutions for bank stabilization. The Design Phase included preparation of plans and details, application of environmental permits, and solicitation of bids from area contractors.  Following the award of the contract, TVGA assisted the Village with construction support services, including, shop drawing review, site inspection, and construction management duties.  Throughout the duration of the project, TVGA cooperated with the State Emergency Management Office, who was administering the Federal Emergency Management Agency’s grant monies. This grant administration phase included regular communication on scope-related issues, and preparation of quarterly reports that summarized the project’s schedule and budget status.
