Full Breakdown
04. The table's specification requires that 'rain water is captured and recycled for landscape or golf course irrigation' and that the project's Master Plan 'indicate how this will be accomplished', meaning the developer must show, at the plan-review stage, the actual capture and irrigation-reuse system rather than simply asserting the feature. It sits alongside a parallel 'Gray Water Reuse' credit, also worth 2 points, for water from dish, shower, sink and laundry use that is similarly reused for landscape or golf course irrigation with the same master-plan documentation duty, and a 'Rain Gardens' credit worth 1 point per bioretention system (up to 4 points) that specifies a minimum 100-square-foot system sized between five and ten percent of the impervious area draining to it, built with native plants over a sand/soil matrix.
02, O-1, C-1, C-2, C-3, C-4, I-1, I-2, the Education Institutions District and the Waterfront Special Use District, and only as one option among many a developer can choose to reach the required point total; it is not a county-wide requirement that every project reuse rain water.
Violations & Fines
Rain-water reuse itself is not separately penalized; it is an optional credit toward the mandatory Green Development point total under UDC § 832.04. A covered project that fails to document its required point total, whether or not it uses this credit, is out of compliance with § 832 and can be denied site plan approval, or pursued by the Zoning Officer under the general misdemeanor enforcement of § 1409 if built without meeting the requirement.
