Agenda Analysis
Analysis
This ordinance authorizes a participation agreement between the Metropolitan Department of Water and Sewerage Services and Fisk University (“Fisk”) to provide improved green stormwater infrastructure through the construction of a green roof.
Per the agreement, Fisk would contract and oversee the construction of a 11,440 square foot green roof on its Allied Science Building, which will meet all specifications and requirements in Metro Water’s Stormwater Management Manual. Metro Water has determined that the project will benefit Metro Water’s overall systemic needs and agreed to contribute $150,000 to the project.
Metro Water remains under a consent decree that requires the reduction of stormwater into its combined sewer system. The provision of the green stormwater infrastructure would reduce the amount of stormwater directed to the combined sewer system and reduce the potential for localized storm flooding.
This legislation has been approved by the Planning Commission. Amendments to this legislation shall be approved by resolution.
Fiscal Impact: Metro will pay Fisk University a contribution, not to exceed, $150,000 towards the green infrastructure project.
