Commission debates allowing landscape rock or gravel as parking surface, but declines immediate change
Summary
After public comment and staff analysis, commissioners expressed concern about erosion, drainage, maintenance and enforcement challenges and indicated no appetite to amend the hard-surface definition to allow landscape rock or loose gravel for parking.
City staff brought forward a resident request to allow landscape rock or gravel to qualify as a "hard surface" so it could be used for parking and storage. Under current code "hard surface" includes impervious or designed-pervious pavements such as asphalt, concrete or pavers; permitting rock or gravel would require an amendment to the municipal code.
Resident Matt Petty described installing landscape rock adjacent to his driveway to park a trailer; he said he did not want to incur the cost of a poured-concrete pad or full pavers. Petty said his installation used larger landscape rock and a plastic edging to contain it.
Staff and multiple commissioners raised concerns about differences between rock and gravel in practice, the potential for rock to erode into curbs and storm drains, weeds and maintenance, and difficulty in drafting a clear regulation that distinguishes acceptable rock from unacceptable gravel. Staff noted drainage and erosion-control rules treat packed gravel differently than permeable pavers and that allowing loose material without strict installation standards could increase enforcement burden.
Commissioners discussed technical work-arounds, including engineered grid systems that stabilize rock, edging to contain material and specifications for stone size and base installation, but expressed concern that the many permutations could produce inconsistent results across properties. After extended discussion, the commission concluded the potential downsides and enforcement complexities outweighed the benefits and indicated no support for an immediate code change. Staff said the item remains available for future code development if commissioners request language and standards to be drafted for formal consideration.
Outcome: No ordinance change was adopted at the meeting. Commissioners instructed staff to retain the current definition and to bring a draft ordinance forward only if the commission requests specific installation standards and regulatory language.
