Consultant: Stormwater inventory underway; crews mapping inlets and seeking public works help
Summary
Rivers and Associates told Bethel commissioners they have compiled town mapping into GIS and are GPS-locating inlets and outlets (an estimated 30,000 linear feet of storm main). The firm requested public works assistance to clear sediment-clogged inlets and noted CCTV inspection will require additional funding.
Rivers and Associates updated the Bethel Board of Commissioners on the town's stormwater asset inventory and fieldwork.
Scott Godfrey, the Rivers representative, said the firm compiled available mapping into a GIS and began GPS locating inlets and outlets in early January. Based on the mapping, Godfrey estimated roughly 30,000 linear feet of storm line in town, with pipe diameters generally in the 12' to 24' range.
Godfrey described the fieldwork method: crews grid the town to map the system, mark inlet locations with paint and record elevations and invert depths when accessible. He said many inlets are currently filled with sediment or debris, which prevents measuring internal pipe geometry; in those cases Rivers needs the town's public works staff to clear sediment so technicians can obtain measurements.
Godfrey said some sections are difficult to access and that the contract does not include CCTV inspection of pipe interiors; he said CCTV would add cost but could be targeted to priority lines once the inventory identifies problem areas. He reported staff expect to finish initial measurable locations within about two weeks, subject to weather and access.
Commissioners asked about numbering, spray-paint marking and the assistance Rivers will need from public works; the manager and Rivers agreed staff would support clearing access points for measurements.
The update did not include policy decisions or funding approvals; Rivers asked the board to consider budgeting for CCTV or cleaning work after the inventory identifies priority segments.
