All storm water conveyances within or parallel to and adjacent to the public right-of-way that are not designed as an approved storm water BMP or component of a low impact development plan shall be fully contained in storm sewers with an adequate and approved outlet. Residential subdivisions containing lots of less than 15,000 square feet and non-residential subdivisions shall be provided with storm sewers to convey all on-site drainage. However, on-site drainage swales with required conveyance capacity of less than five cubic feet per second under the ten-year post-development design storm may be allowed.
