Ross Municipal Code § 15.54 Referenced Standards

15.54.010 Low impact development for stormwater management and requirement for drainage

plans. (a) No down spouts shall be connected directly to the Town storm drain system or enter directly into any water course or creek without first going through a treatment area (such as flowing over a landscaped area, lawn or French drain, or other area that cleans, filters, slows the speed and amount of water leaving a property), or to an approved alternate location based on approved geotechnical and engineering designs.

(b) The Town may require a drainage plan for any construction and renovation projects subject to a building permit, which, as determined by the town building official, may result in an increase to site runoff. The plan shall be designed, at a minimum, to produce no net increase in the rate and volume of peak runoff from the site compared to pre-project conditions (no net increase standard). Applicants shall reduce peak runoff from the site compared to preproject or pre-development conditions.

(1) The Town may require a hydrologic/hydraulic analysis to be prepared and

submitted.

(2) The Town may establish standards for the drainage plan and analysis.

(3) The Town may require that construction of drainage facilities be supervised, inspected and accepted by a professional engineer, a letter of certification prior to project final, and preparation and submittal of certified as-built drawings of the constructed facilities.

(4) Property owners shall be responsible for inspecting and maintaining drainage facilities. The Town may require an applicant to enter into and/or record a maintenance agreement for drainage facilities.
