Monmouth public works reports heavy street-cleaning gains, new GIS asset inventory planned
Summary
Public works reported inspection of all 36 outfalls twice in 2025, about 69.5 tons of street debris swept and roughly 480 cubic yards of leaves removed this year; staff will deploy a GIS asset system (Diamond Maps) in 2026 to inventory catch basins, outfalls and other storm assets and to improve tracking and illicit‑discharge response.

Monmouth’s public works department told the City Council Dec. 2 that its 2025 stormwater work reduced pollution risks, expanded riparian restoration and will soon include a GIS‑based asset inventory.
Public Works Director Mark Landau said the city submitted its annual Total Maximum Daily Load (TMDL) accomplishment report to the Oregon Department of Environmental Quality on Nov. 19 and implemented expanded field work this year. Staff inspected all 36 storm outfalls twice and updated inspection forms to capture pipe size and material. Crews and contractors removed 69.5 tons of street debris via street sweeping and collected about 480 cubic yards of leaves, Landau reported.
Landau also summarized habitat and restoration work: the city and partners planted roughly 507 potted trees and 3,100 bare‑root trees (a combined total cited as 3,607 trees and shrubs), removed invasive species along Ash Creek and worked with the Lucky Mute Watershed Council and local volunteers on riparian restoration.
Councilors asked whether the city’s stormwater fee was providing tangible benefits. Landau said fee revenue funded a new stormwater technician position that expanded inspections, maintenance and illicit‑discharge response. He told the council the department expects to jet‑clean and TV‑inspect storm lines in 2026, clean 50% of catch basins and finish a GIS asset inventory of catch basins, manholes and outfalls using Diamond Maps.
Councilors urged the department to publicize accomplishments (tons removed, leaf haul, new staffing) and to use the new asset data to provide consistent inventory counts for future reporting.
What’s next: staff will continue implementing the 2023–28 stormwater matrix, begin GIS asset collection in 2026 and report more precise load and weight numbers at year end.
