Commission discusses whether landscaped rock or gravel can count as 'hard surface' for parking; no code change yet

At its meeting the Planning and Zoning Commission discussed whether to amend the definition of “hard surface” to permit certain landscaping rock or gravel as an approved surface for vehicle parking. Staff said current code defines hard surface as impervious materials such as asphalt, concrete, or pervious pavers and that allowing rock or gravel for parking would require an explicit code amendment. Resident Matt Petty said he moved landscaping rock and parks trailers on it and argued, “Rocks are hard,” adding that a properly contained rock surface could serve the homeowner’s needs without the cost of concrete or pavers. Staff and commissioners raised concerns about erosion, rocks mobilizing into curb lines and storm drains, different drainage/permeability behavior compared with approved pervious pavers, and the practical difficulty of drafting and enforcing a granular standard distinguishing 'rock' from 'gravel.' One staff member cited a nearby lot with widespread gravel and trailers as an example of problems that can arise when gravel is used as a parking surface. Commissioners cited installation technique, containment borders and engineered grid systems as possible mitigations but noted the need for precise language (rock size, compaction, edging, subbase and maintenance requirements) before allowing a broader exception. The item remained a discussion topic; commissioners asked staff to refine options and specific installation standards for future consideration rather than adopt an immediate change.
