9-14-5: POSTCONSTRUCTION:
This section is included in your selections.

A. Standards To Minimize Impacts On Water Quality: New development and redevelopment projects must have requirements or standards to ensure that any storm water controls or management practices will prevent or minimize impacts to water quality.

B. Standards To Minimize Development In Susceptible Areas: New development and redevelopment projects includes nonstructural BMPs such as requirements and standards to minimize development in areas susceptible to erosion and sediment loss; to minimize the disturbance of native soils and vegetation; to preserve areas in the municipality that provide important water quality benefits; to implement measures for flood control; and to protect the integrity of natural resources and sensitive areas.

C. Projects Greater Than Or Equal To One Acre: Newly developed and redeveloped projects that disturb greater than or equal to one acre, including projects less than one acre that are of a larger common plan of development or sale, shall include a process to evaluate and encourage a low impact development (LID) approach which encourages the implementation of structural BMPs, where practicable, that infiltrate, evapotranspire or harvest and use storm water from the site to protect water quality. Structural controls may include green infrastructure practices such as rainwater harvesting, rain gardens, permeable pavement, and vegetative swales. The selection and design of postconstruction controls shall take into consideration clogging or obstruction issues, freeze-thaw problems, effect on slope stability and groundwater, and the ability to effectively maintain the control.

D. Specific Criteria: Newly developed and redeveloped projects must meet specific criteria which require that best management practices (BMPs) are designed to treat the water from a specific design storm (the 2-year, 24-hour event, etc.) must be incorporated into the permittee postconstruction minimum control measure and documented in the storm water pollution prevention plan. Permittee may allow other unique or complex methodologies.

E. Inspections: Owners/operators of newly developed and redeveloped projects shall conduct inspections and perform any necessary maintenance at least annually. This required inspection shall be conducted by a registered storm water inspector (RSI). On sites where the property owner/operator is conducting maintenance, the permittee shall allow municipal inspections to conduct inspections at least once every five (5) years, or more frequently as needed to show that adequate maintenance is being performed.

F. Stabilization Requirements: Any area that has been disturbed by grading activity shall be stabilized according to a schedule provided by the contractor or the owner/operator and approved by the city of St. George. A plan must be submitted with the final design describing the vegetative or other stabilization and management techniques to be used at a site. This plan will explain not only how the site will be stabilized, who will be responsible for the maintenance of vegetation or other stabilization at the site, and what practices will be employed to ensure that adequate cover is preserved.

G. Inspection Of Storm Water Facilities: Periodic inspections of facilities shall be performed by the city of St. George on public property. On private property, the landowner, its successors and assigns, including any homeowners’ association, shall conduct periodic inspections and maintain the storm water facilities. This includes all inlets, pipes, channels, and detention basins built to convey storm water, as well as all other structures, improvements, and vegetation provided to control the quantity and quality of the storm water. “Adequate maintenance” is defined as good working condition so that these storm water facilities are performing their designed functions. An annual inspection report must be filled out for storm water facilities located on private property and retained for three (3) years to ensure that the facilities are in good working condition and acceptable to the city of St. George. The owner must provide the records for the city of St. George upon request.

H. Records Of Installation And Maintenance Activities: Parties responsible for the operation and maintenance of a storm water facility shall make records of all maintenance and repairs to the facility, and shall retain the records for at least three (3) years. These records shall be made available to the city of St. George upon request.

I. Failure To Meet Or Maintain Design Or Maintenance Standards: If a responsible party fails or refuses to meet the design or maintenance standards required for storm water facilities, the city of St. George, after reasonable notice, may correct a violation of the design standards or maintenance needs by performing all necessary work to place the facility in proper working condition. In the event that the storm water facility becomes a danger to public safety or public health, the city of St. George shall notify in writing the party responsible for maintenance of the storm water facility. Upon receipt of that notice, the responsible person shall immediately repair the facility in an approved manner. In the event that corrective action is not undertaken within that time, the city of St. George may take necessary corrective action. The cost of any action by the city of St. George under this section shall be charged to the responsible party and a lien placed on property for payment. (Ord. 2015-11-006, 11-19-2015; amd. Ord. 2019-04-001, 4-4-2019) (Ord. 2019-04-001 § 2, 2019; Ord. 2015-11-006, 2015.)
