City of Murfreesboro


The City of Murfreesboro has enacted a Stormwater Management Ordinance in order to manage the manner in which stormwater is addressed in areas of new development and redevelopment through the course of construction, post‐construction stabilization and permanently to maintain or benefit water quality, to provide measures against stream bank erosion and flooding, and thereby to benefit the quality of life and character of the City. The City of Murfreesboro 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 Murfreesboro will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. Stormwater fees will be collected by the City of Murfreesboro and businesses can qualify for credits by implementing Best Management Practices on their property. The City of Murfreesboro, 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.

2. Ongoing Maintenance Inspections

Ongoing inspection and maintenance of a project site’s stormwater management system shall occur from time to time by the City of Murfreesboro.

Preparation of maintenance plans shall be a requirement of the Stormwater Management Site Plan preparation and review process. A maintenance plan shall outline the scope of activities, schedule, costs, funding source, and responsible parties. Vegetation, sediment management, access, and safety issues should also be addressed. In addition, the plan shall address the testing and disposal of sediments that will likely be necessary and the ultimate replacement of structures as needed.

The City’s goal is for annual inspections of stormwater management facilities to be conducted. Where chronic or severe problems exist, the City of Murfreesboro shall have the authority to remedy the situation and charge the responsible party for the cost of the work. This authority shall be a requirement in the City of Murfreesboro’s Post-construction Stormwater Ordinance.

Stormwater Maintenance Fee

The city of Murfreesboro (City) stormwater user fee is a mechanism for recovering the costs of operating and maintaining the City’s stormwater management system, and funding the necessary capital improvements, repairs, replacements, other improvements, and extensions of the City’s stormwater management system. The City intends to encourage sound technical design practices which reduce the impact of development on the City’s stormwater system through a simple and effective stormwater credit system for non-single family residential property owners. The credit system incorporates an efficient and equitable appeal and stormwater fee adjustment if the City has calculated an incorrect value of impervious area on a non-single family residential property and a credit process for owners of non-single family residential properties who are charged a stormwater user fee.

The basis and emphasis for the credit system is the implementation of stormwater management controls (stormwater management facilities, best management practices (BMP), BMP treatment train) that are designed, operated, and maintained to treat stormwater runoff and/or to mitigate the effects of increased stormwater runoff peak rate, volume, and velocity due to impacts of impervious area as a result of development and redevelopment. The stormwater management control and credit philosophy is based on the approach that the stormwater management controls:

• reduce pollutants in stormwater runoff;

• regulate stormwater peak flow and volume from a non-single family residential property development or redevelopment to minimize downstream stormwater conveyance system erosion; and,

• regulate stormwater peak flow and volume from a non-single family residential property development or redevelopment to minimize flood risk to upstream, adjacent, and downstream properties.

Credits to Stormwater User Fee

Credits to stormwater user fees are available to owners of non-single family residential properties who implement onsite stormwater management controls that provide peak runoff and/or volume control, stormwater quality best management practices, and proper operation and maintenance of the onsite stormwater management facilities. Establishing credits to the stormwater user fee in the context of a stormwater utility achieves greater flexibility in protecting water quality and aquatic habitat in urban watersheds at a lower overall cost to the City. Credits allow property owners to choose the most cost effective development option for their property; pay appropriate stormwater user fee to fund City stormwater management services; or implement onsite stormwater management facilities and pay a reduced stormwater fee.

Adjustments to Stormwater User Fee

The City will grant an adjustment when non-single family residential property owners identify incorrect total impervious areas contained in the City’s database.

CREDITS TO STORMWATER USER FEE

Credits applicable to the stormwater user fee are only available for non-single family residential property owners. Non-single family residential property owners can apply for a combination of credits. The credit for flood control volume reduction (stormwater quantity) will be based on a case by case basis; credit for stormwater quality is 15 percent; and, credit for streambank protection volume control is 25 percent. Flood control volume, streambank protection volume, and stormwater quality control requirements could be accomplished with one BMP or through a series of BMPs, i.e., BMP treatment train. In summary, five types of stormwater user fee credits are available:

• Flood Control Volume Credits (case by case basis), Qf

• Streambank Protection Volume Credits, SPv

• Stormwater Quality Credits, WQv

• Education Credits

• NPDES Stormwater Permitted Facilities Credits

STORMWATER MANGAGEMENT FACILITY OPERATION AND MAINTENANCE

Non-single family residential properties that receive credit applicable to the stormwater user fee for flood control volume and water quality control stormwater management facilities (BMP treatment train) must keep the facilities properly maintained. Non-single family residential property owners shall maintain the facilities to standards established by the City; shall document all operation and maintenance activities; and shall provide the MWSD, upon request, all records associated with operation and maintenance of stormwater BMP’s utilized for receiving a stormwater fee credit. Certifications may be required in instances where stormwater BMP’s must be operated and maintained with specialized equipment or trained operators.

Any credit allowed for non-single family residential properties has the condition that the stormwater management facilities must maintain continuous compliance with standards established in the Stormwater Controls Manual. The City may revoke a credit at any time for non-compliance.

The revocation will be in effect from the estimated time period that it is determined that the stormwater BMP or BMP treatment trains was not functioning, but shall not exceed six (6) months.
