SFR Ponds Program


 

SFR 1

 

What is stormwater?

In a natural setting such as a forest or meadow, when it rains the water is absorbed into the ground & then taken up by plants & vegetation. Once we start building on these natural areas, they become taken up by hard impervious surfaces like roofs, roads, & parking lots. The natural cycle is then disturbed, creating excess water that can't soak in & runs off of these surfaces. That water is called stormwater runoff. It can carry pollution, as well as overwhelm our natural systems, causing flooding.

What is a stormwater pond?

Stormwater ponds are engineered depressions meant to be a solution to this problem. They temporarily hold stormwater runoff, & promote pollutant removal through sedimentation. They reduce erosion of nearby creeks and streams that would be inundated with water, and they also reduce flooding by releasing the captured water at a controlled rate. This makes them great devices to improve both the quantity and quality of our stormwater.

There are 3 main types:

  • Retention
  • Detention
  • Naturalized basin

 

Detention ponds

Detention ponds should be dry the majority of the time, unless it is soon after a rain event

Retention ponds

Retention ponds have water present year round

Naturalized basin

Naturalized basins have the added benefit of native vegetation which provides support for our ecosystem, as well as aiding in the uptake of water. *Be aware, an overgrown detention pond is NOT a naturalized basin. Naturalized basins are planted or seeded intentionally with beneficial native species*

About the SFR Ponds Program

The City recently revised the Ordinance (No. 13486) which addresses how Single Family Residential (SFR) Ponds are to be maintained. Referring to Section 31-314.E, the City is in the process of assessing all SFR Ponds to determine appropriate maintenance procedures.

The Single Family Residential Retention & Detention Pond Maintenance Program (SFR Ponds Program) is an initiative to improve the condition of detention & retention stormwater ponds that are privately owned, improve water quality & educate citizens about stormwater control measures (SCMs).

 

  • These ponds will be assessed and prioritized by the City for an initial rehabilitation if needed, and/or possible retrofitting for water quality improvements
  • After this initial improvement, the City will take over doing functional maintenance
  • General maintenance will still be the responsibility of the property owner(s) or homeowner's association
  • Applying does not automatically enroll you in the SFR Ponds Program. Acceptance into the program is up to the discresion of the Water Quality Program
  • A new single family residential pond must wait two years from date of acceptance by HOA, final stabilization, and closure of permit to apply to the program
  • If property owner(s) withdraw from the Rainwater Management Guide (RMG) required maintenance of their SCM before the property is put into the Program, i.e. before the City officially notifies the Owner(s) that the City’s maintenance will begin, or if they opt out of the program during it- the owner(s) will be subject to the City’s Enforcement Protocols
  • Farm ponds are not stormwater control measures and will not be considered for the program

 

How does the program work?

  1. The property owner must apply for the program APPLY HERE - approval pending by Water Quality (WQ) staff
  2. Home owner must agree to & sign a hold harmless agreement. Submit this to ChattanoogaWQ@chattanooga.gov
  3. Pond is inspected by WQ professional - easements identified, site assessed (If you do not have an easement currently established for City staff to enter the property for maintenance, an easement agreement must be signed)
  4. A task order will be created specific to your pond's needs
  5. A WQ professional will meet with the contractor on site to go over the repairs needed
  6. Maintenance is done to get pond in working order
  7. A maintenance schedule will be established for general maintenance going forward
