City unveils draft interactive map to show maximum impervious coverage for single-family lots

City planning staff demonstrated a draft interactive tool on Sept. 23 that will let single-family property owners determine the maximum allowable impervious coverage on their lots.

Brad Parish, planning staff, said the tool will be added to the city's online story maps and will show parcel-level information including maximum square feet allowed for impervious surfaces (buildings, driveways, sidewalks and similar surfaces). Parish said the review focused only on single-family lots and that only a limited number of properties in Titusville are controlled by the Area of Critical Concern ordinance.

Parish reminded council the core ordinance was adopted in 1986 and amended in 2005 to add well-field protections, meaning subdivisions approved before 1986 are often not affected, while newer subdivisions and some plan-unit developments may have developer-imposed limits and require special attention.

The demonstration showed that owners will be able to zoom to specific parcels or enter an address to see the maximum impervious square footage and how much of the lot is already covered. Parish said the map is draft and not yet published; staff will add it to the city's other maps after review.

Council members asked whether the map covered only areas inside the Area of Critical Concern and whether it would indicate whether features such as pools would be allowed. Parish replied the tool includes subdivisions where developers imposed impervious limits and will display the maximum square feet allowed so owners can determine if a pool is feasible.

Why it matters: impervious coverage limits affect homeowners' ability to add pools, driveways and other improvements and are tied to water-resource protections in the city's well-field areas.
