title

An ordinance requiring the Metropolitan Department of Water and Sewerage Services to prepare a Stormwater Masterplan evaluating existing infrastructure throughout Davidson County in relation to current Stormwater Management Manual Standards and to provide a report to the Metropolitan Council by July 1, 2023.

 

 

body

WHEREAS, in order to effectively meet existing and anticipated stormwater infrastructure, water quality, and flooding preparedness, establishment of a stormwater fee was authorized by the Metropolitan Council in 2007 pursuant to Ordinance No. BL2007-1440. A subsequent comprehensive review of stormwater fees resulted in an adjustment in 2017 per Ordinance no. BL2017-588. The modernized fee structure allows Metro Water Services to address both current and future needs of the stormwater system, including an estimated $200 million backlog of stormwater capital projects; and

WHEREAS, the Metro Water Services Department has been using stormwater fee revenues to perform maintenance and repairs and to construct capital improvements since 2009; and

WHEREAS, to maintain and address stormwater infrastructure needs throughout Davidson County, it is necessary for the Metro Water Services Department to conduct a countywide assessment to prepare a Stormwater Masterplan which comprehensively evaluates and identifies capital projects necessary to correct existing deficits and prevent potential problems; and

WHEREAS, the Metropolitan Nashville - Davidson County Stormwater Management Manual, as currently applied, was adopted in February of 2016; and

WHEREAS, Chapter 6 of the Metropolitan Nashville - Davidson County Stormwater Management Manual, labeled “Technical Guidelines and Criteria”, provides current dimension specifications and other regulatory provisions for stormwater infrastructure, including culverts, inlets and storm drains; and

WHEREAS, stormwater infrastructure in many rural and suburban neighborhood portions of the General Services District -- including those areas within the T2- Rural Neighborhood Policy and T3- Suburban Neighborhood Policy -- is increasingly strained by the competing demands of development and stormwater management; and

WHEREAS, the Stormwater Masterplan will be a countywide initiative incorporating a watershed management approach that will provide guidance for development and the management of capital projects.  The Stormwater Masterplan shall have a reporting component that can provide updates for council districts or neighborhood transects such as T2 and T3; and

WHEREAS, while capital budget funding must be allocated across multiple competing priorities, the stormwater infrastructure needs must be maintained and/or rectified.

NOW, THEREFORE, BE IT ENACTED BY THE COUNCIL OF THE METROPOLITAN GOVERNMENT OF NASHVILLE AND DAVIDSON COUNTY:

Section 1. The Metropolitan Department of Water and Sewerage Services shall prepare a Stormwater Masterplan, evaluating and inspecting existing infrastructure throughout Davidson County in relation to the current Stormwater Management Manual Standards as adopted February 2016 and the NashvilleNext long-term growth plan adopted in 2015, investigate open service requests, conduct public meetings, identify potential projects to address stormwater problems or system deficiencies, and prepare preliminary cost estimates to establish a multi-year capital improvement plan. A report identifying upgrades needed to conform to Manual Standards, and the cost of such upgrades, shall be provided to the Metropolitan Council by July 1, 2023. If necessary, the completion date can be extended to December 31, 2023 by resolution, with Metro Water Services providing an interim update to the Council by July 1, 2023.

Section 2. Be it further enacted that this ordinance take effect immediately after its passage, the welfare of The Metropolitan Government of Nashville and Davidson County requiring it.

 

Agenda Analysis Analysis This ordinance, as substituted, would require Metro Water Services to prepare a stormwater master plan evaluating existing stormwater infrastructure throughout the county, and to submit a report to the Metro Council not later than July 1, 2023. The master plan process would include an investigation of open service requests, the identification of potential projects to address stormwater problems, and to prepare cost estimates. The report to be provided to the Council is to identify the upgrades needed to conform to the Stormwater Management Manual standards and the cost of such upgrades. The due date for the report could be extended up to six months by resolution.
