Monroe County debates gravel classification as impervious surface in stormwater ordinance

The Monroe County Plan Commission meeting on May 20, 2025, focused on the classification of gravel as an impervious surface in local stormwater regulations. The discussion highlighted differing opinions among commission members and stormwater staff regarding the impact of gravel on water infiltration and drainage.

Erica Pena, the stormwater program manager, stated that gravel should be considered an impervious surface due to its tendency to compact over time, which inhibits water infiltration. This perspective aligns with the drainage board's stance, which also categorizes gravel under impervious surfaces. However, some commission members expressed concerns about this classification, arguing that grass can grow through gravel, suggesting that not all gravel installations should be treated the same.

Mr. Farris raised the need for a clear definition of gravel, including its density and depth, to avoid ambiguity in enforcement. He noted that in rural areas, gravel may not always function as an impervious surface due to the presence of vegetation. Other members, like Mr. Busch, acknowledged the challenges in creating a uniform standard for gravel but leaned towards including it as impervious, allowing homeowners to request variances for unique situations.

The conversation also touched on the historical context of impervious surfaces in Monroe County, with long driveways identified as significant contributors to impervious cover. The commission aims to balance existing property conditions with new developments to minimize environmental impact.

In conclusion, the commission's ongoing discussions reflect a complex interplay between environmental regulations and practical considerations for homeowners. The next steps will involve further examination of gravel's classification and potential adjustments to stormwater management policies.
