See section 514.5 of the Development Ordinance for storm water basic design criteria.
514.4 Storm Water Management
These regulations affect all subdivision and development of land within the City of Richmond.
Storm sewer systems are designed to collect and convey storm water runoff from street inlets, runoff control structures, and other locations where the accumulation of storm water is undesirable. The objective is to remove runoff from an area fast enough to avoid unacceptable amounts of ponding damage and inconvenience.
In general, the amount of storm water runoff should be equal in terms of pre-development and post-development given the design of the storm water system. Storm water runoff from a site or subdivision shall not adversely impact natural drainage from an uphill drainage basin or to a downhill drainage basin or adjacent properties. The property owner shall be responsible for storm water drainage facilities located on private property where runoff will be collected within that property and be minimally discharged over a larger area before the storm water naturally drains on adjacent properties unless a large drainage basin exists or is being planned. Storm water drainage easements shall be required if storm water is discharging directly from a pipe to an adjoining property and being dispersed on the property. No storm sewer construction shall occur until permission has been granted by the appropriate agency. All storm water infrastructure components shall be inspected and certified by the owner/developer's engineer.
In addition, the City of Richmond operates under the requirements of the Kentucky Pollutant Discharge Elimination System (KPDES), under which the city must develop, implement, and enforce a program to reduce pollutants from any storm water runoff resulting from construction activities that result in a land disturbance grater than or equal to one (1) acre. Accordingly, all construction site development of one (1) acre or more must provide the following information before commencement of construction activities:
- Provide the city's Code and Planning Office with a signed copy of the completed Notice of Intent (NOI) form, KPDES Form NOI-SW within forty eight (48) hours prior to the initiation of site work.
- Provide a completed copy of the site-specific Best Management Practices Plan at a scale not greater than 1"=50 feet to the city's Code and Planning Office at the time of request for a development plan review by the Planning Commission. This information shall be available for review by the Technical Advisory Committee at its regular meeting.
- Provide the city with any updates to the Best Management Practices Plan made during the actual construction process, within twenty-four (24)hours of final design.
- Provide the city with a signed copy of the Notice of Termination (NOT) within forty-eight (48) hours of submittal to the state.
As provided for in Ordinance 03-57, the city has the right to 1) enter and inspect construction sites with any land disturbances for the presence of properly installed and functioning sediment control Best Management Practices and to assure compliance with the BMP site specific plan, 2) to review the records of the permittee and/or his contractor at both on-site and off site locations that pertain to the development, installation, maintenance, and operation of the BMP Plan, and 3) to require modification to the BMP Plan along with the correlating physical placement of the modifications at the site, when in the opinion of the city the current BMPs are not functioning to the degree necessary to prevent or minimize erosion or to provide proper sediment control. All expense for modifications required by the city shall be borne by the permittee and/or his contractor. No expense for proper maintenance or operation shall be borne by the city.
Where the permittee and/or his contractor is found to be in non-compliance, each non-compliance item shall be corrected within five (5) working days of notification. The first occurrence of non-compliance shall result in an issue of Notice of Violation; the second occurrence or continued non-compliance shall result in a stop work order; the third occurrence or continued non-compliance shall result in a five hundred dollar ($500) fine per calendar day of non-compliance along with a filing of a complaint with the Kentucky Division of Water. The city has the right to take civil action against any permittee and/or contractor that consistently and persistently fails to comply with the requirements of Ordinance 03-57.
