Summary
Rose Hill's subdivision ordinance puts stormwater drainage on the developer, not the town. Under Code of Ordinances § 153.15(D), surface water can never be run into a sanitary sewer, and a subdivider must tie into the public storm sewer whenever the Planning Board finds one reasonably accessible, at the subdivider's own expense, before the final plat is accepted.
(D) Surface water drainage. (1) No surface water drainage shall empty into a sanitary sewer. (2) Where, in the opinion of the Planning Board, a public storm water sewer is reasonably accessible, before a subdivision is approved and accepted by the town, the subdivider shall connect with the public storm sewer system by providing all grading and all structures necessary to carry the water to the storm drainage system. Drainage and construction of drainage structures shall conform to town specifications and standards. (3) Where a storm drainage system is not accessible, before a subdivision is approved and accepted by the town, the subdivider shall do all grading and provide all drainage structures necessary to properly carry the water to locations which are acceptable to the town. (4) Where drainage ditches are provided and grades exceed 4%, the ditches shall be paved in accordance with the town standards.
Full Breakdown
Chapter 153, the town's subdivision ordinance, treats stormwater as an improvement the developer must design and pay for before Rose Hill will accept a plat. 15(D) sets the specific drainage rules. First, surface water drainage can never empty into a sanitary sewer line; the two systems must stay separate. Second, if the Planning Board decides in its own judgment that a public storm water sewer is reasonably accessible to the site, the subdivider has to connect to it, doing all the grading and building all the structures needed to carry water to that system, built to the town's own specifications and standards.
Third, where no public storm system reaches the property, the subdivider still has to grade the land and install whatever drainage structures move the water to a location the town finds acceptable; the obligation to manage runoff does not disappear just because there is no public line nearby. Fourth, if a drainage ditch is part of the design and its grade exceeds 4%, the ditch must be paved to town standards rather than left as bare earth, controlling erosion on steeper runs. 27 before the Board accepts the final plat.
Because the rule is tied to plat approval, a developer who skips the drainage work risks having the subdivision rejected outright, not just fined after the fact.
Violations & Fines
Subdividing land without meeting the drainage and improvement standards of Chapter 153, or selling lots by reference to an unapproved plat, is a Class 1 misdemeanor under § 153.99. The town may sue for an injunction ordering compliance, deny building permits for the illegal subdivision, and take any other action to restrain or abate the violation. The Subdivision Administrator can also invoke the Zoning Code's separate enforcement remedies at § 154.999.
