Who maintains county ponds? Agencies explain split between structural and aesthetic responsibilities

County staff clarified a two-part maintenance framework for stormwater management facilities.

Joanna Smith of DPW&T said DPW&T is responsible for "functional and lifecycle maintenance" of county public stormwater facilities, naming tasks such as sediment removal, riser and pipe repairs, embankment safety and access-road maintenance. "DPW and T is responsible for all the functional and lifecycle maintenance of all county public stormwater management facilities," she said.

DOE representative Nairi Wyand explained DOE inspects privately owned BMPs on a triannual schedule and issues compliance letters and corrective-action timelines to private landowners. "Those letters are issued, letting the landowner know that the facility is either in compliance or not in compliance," Wyand said, noting owners have 30–45 days to address deficiencies or negotiate a schedule.

Ray DeGuzman (DPIE) described how maintenance agreements are recorded during permitting and run with the land, obligating future owners to maintain ESD (environmental site design) practices and, in many residential cases, static/aesthetic upkeep by HOAs while structural flood-control responsibilities remain with public works. "We require them to sign and execute and record a maintenance agreement...that runs with the land," DeGuzman said.

Task force members expressed concern that HOAs often don’t receive or understand these documents; staff agreed better communication and education are needed. The agencies committed to follow-up to identify gaps where deeds and inspection records may not be readily accessible to homeowners.
