What is a SCM?

Stormwater Control Measures refer to what is defined by EPA as "a technique, measure, or structural control that is used for a given set of conditions to manage the quantity and improve the quality of stormwater runoff in the most cost-effective manner."


What is an Inspection & Maintenance Agreement (IMA)?

In accordance with Ordinance 11883:

Property owners of sites that were developed or retrofitted after September 26th, 2006 to include SCMs on the property, are required to have signed an agreement with the City called an Inspection & Maintenance Agreement or IMA. This document must be signed, notarized, and include the correct ancillary documents.

This agreement requires the property owner to keep up with maintenance on their SCMs by inspecting them quarterly, & sending in an annual report of maintenance done to the City's Water Quality Program.

Ancillary documents included in the IMA that help the property owner & the City to better keep up with maintenance needs:

  • Exhibit A: Legal Description of property
  • Exhibit B: Plan for maintenance procedures, called a Long Term Maintenance Plan (LTMP).
  • Exhibit C: Map of the site with SCMs labeled.



List of sites that currently have a recorded IMA *This list may not be exhaustive, & sites will be added as they are recorded.

If you are required to have an IMA but do not, please contact the Water Quality Program via email at: ChattanoogaWQ@chattanooga.gov


What is required?

All SCMs (e.g., detention ponds, oil skimmers, bioretention ponds, pervious pavement, etc.) shall be inspected at least quarterly.

The collection of these quarterly reports shall be submitted annually to the City Water Quality Program. Directions for annual submission and a copy of the latest Inspection and Maintenance Form are provided below.

*NEW* Beginning January 2021, all inspection and maintenance forms (I&M Form) shall be signed by a certified individual. The City shall consider an individual as certified if they have attended and are in good standing with both the City's SCM I&M Workshop and the State's Permanent Stormwater Management Training course.

The below link for City Recognized SCM I&M Vendors is a list of companies who perform SCM inspection and/or maintenance.

This list contains companies with varying abilities and degrees of expertise. It is recommended that a property owner obtain at least three bids prior to contracting with a company. The City does not recommend or endorse one company over another. If the company you're currently using or desire to use is not on the list, you may have that company contact the Water Quality Program (ChattanoogaWQ@chattanooga.gov) to obtain information about or RSVP for the next scheduled workshop.
