The City of Jackson has enacted a Stormwater Ordinance in order to comply with the federal Clean Water Act. The City of Jackson is the permitting authority for all land disturbing activities and requires the land owner to maintain all on-site stormwater control facilities and all open space areas (e.g. parks or “green” areas) required by the approved stormwater control plan. The City of Jackson will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. The City of Jackson, under the NPDES program, also has the authority to inspect properties for noncompliance and can issue a notice of violation (NOV) for any deficiency or infraction onsite. Property owners are responsible for the maintenance of any stormwater facilities or practices located on the property. The City of Jackson has the authority to inspect stormwater facilities and practices in order to ascertain that they properly maintained and functioning.
Sec. 122-303. - Declaration of nuisance.
It is hereby declared to be a public nuisance for any person to directly or indirectly release significant materials, pollutants, or stormwater, without proper authorization from the director of the department of public works or his designee, in quantities, rates, or concentrations that may reasonably be expected to cause or contribute to any of the following: Damage to a public right-of-way or public storm drain system; a violation of any applicable water quality standard; or a violation of the stormwater NPDES permit for the city.
Sec. 122-304. - Prohibited practices.

Sec. 122-305. - Stormwater management plans for nonresidential users.
(a) Any nonresidential user applying pursuant to any chapter of the City of Jackson Code of Ordinances for authorization, permission, or a permit to construct improvements or conduct other activities on real property that may disturb the ground on their real property, as part of their application for authorization, permission or a permit, shall prepare a detailed, written stormwater management plan for the management of the volume, velocity, and quality of stormwater that has the reasonable potential to be released off-site. Stormwater management plans shall apply to all contiguous land under common ownership or control, and shall specifically state the address of each parcel of property subject to the plan. The plan shall include:
(1) A description of the types of all significant materials that will be on the property;
(2) The land use and materials management practices that could lead to the pollution of stormwater during all phases of existing and proposed land use;
(3) The manner in which significant materials will be used, stored, treated or disposed of;
(4) The methods to minimize, to the maximum extent practicable, the pollution of stormwater; and
(5) Any additional information concerning stormwater management and pollution prevention efforts that are required by state or federal regulatory agencies The stormwater management plan shall be provided to the director of the department of public works or his designee.
(b) A stormwater management plan may cover more than one parcel of property so long as the activities are sufficiently similar that the plan is appropriate. Stormwater management plans need not be resubmitted where any new permits to construct improvements or conduct other activities on real property relate to activities that will not materially change a previously approved stormwater management plan.
(c) Permits, approvals or other authorizations to construct improvements to real property or conduct other activities on real property shall not be issued to nonresidential users pursuant to the City of Jackson Code of Ordinances until the director of the department of public works or his designee has on file an applicable stormwater management plan approved by the director or his designee. Any permits, approvals or other authorizations shall be granted upon the condition that, and be revocable if the permittee fails, at all times, to manage materials in conformity with the stormwater management plan, or if the permittee is responsible for violations of this article. Nonresidential users shall update their stormwater management plan if activities at the affected property are modified in a manner that may cause an increase in the volume, rates, or quality of stormwater released off-site.
(d) Stormwater management plans shall include:
(1) Practicable measures for managing litter;
(2) Practicable measures for managing the use, storage, treatment, and disposal of significant materials;
(3) Practicable measures for managing the use and disposal of pesticides and herbicides;
(4) Practicable measures for reducing the rate of releases to a public storm drain system;
(5) The use of landscape features to reduce the quantity and rate of releases to a public storm drain system;
(6) The use of landscape features to reduce the quantity and rate of stormwater that may be released off-site;
(7) Maintenance of retention basins and other stormwater management devices;
(8) Maintenance and cleaning of parking lots and buildings; and
(9) Ensuring that significant materials are not exposed to direct contact with stormwater.
(e) Drainage calculations shall be submitted analyzing stormwater runoff before and after proposed development. The stormwater rates from the completed construction improvements shall not exceed the pre-construction runoff rates plus one cubic foot per second (cfs). However, if postconstruction runoff exceeds these rates, sufficient detention storage shall be provided to limit project area stormwater runoff to the pre-construction runoff rates.
(f) Stormwater management plan measures shall be designed to control runoff from a 100-year, 24-hour storm occurrence, including all on-site and off-site runoff contributions.
(g) As part of the stormwater management plan, an erosion and sediment control plan shall be required prior to any grading or other earthwork which affects a land area larger than 2,000 square feet, but less than five acres. In the case where the development exceeds five acres, a water pollution control stormwater construction general permit from the Mississippi Department of Environmental Quality shall be required. A copy of the approved permit shall be submitted to the department of public works prior to construction.
(1) The location and types of erosion and sediment control measures shall be graphically indicated on the plans. The plans shall provide sufficient details to assure proper installation and maintenance of these measures during project construction. The maintenance plan shall include the following or a similar note: Care shall be taken to minimize the encroachment of sediment into all storm drain appurtenances, public streets, and on to private property until impervious material (road/parking area surface) is applied or until proposed landscape has been established.
(2) All erosion and sediment control measures shall comply with or be equivalent to the methods outlined in "Planning and Design Manual for the Control of Erosion, Sediment and Stormwater," available through the Mississippi Department of Environmental Quality.
Sec. 122-306. - Stormwater management plans for residential users.

These measures shall be graphically identified on the plans and shall include sufficient details to assure proper installation and maintenance during project construction. The maintenance plan shall include the following or a similar note: Care shall be taken to minimize the encroachment of sediment into all storm drain appurtenances, public streets, and on to private property until impervious material (road/parking area surface) is applied or until proposed landscape has been established.
(2) Identify the postconstruction drainage patterns for the lot or parcel. Where swales are used, the map shall indicate the direction of flow of stormwater.
In addition to the stormwater management plan, the site plan shall identify and denote existing select spot elevations within the property lines of the lot or parcel and identify the finished floor elevation of the proposed structure.
Sec. 122-307. - Inspections.
