Subject

Resolution 2018-10 - Authorizing an Agreement w/Civil & Environmental Consultants for In-Stream Visual Assessments and Monitoring

Background

The Tennessee Department of Environment and Conservation (TDEC) publishes a list of streams in Tennessee that are considered impaired. The list is referred to as the 303d list. Streams can be considered impaired for many reasons, but in urbanized areas like Brentwood the impairment is primarily for siltation (sediment) and loss of aquatic habitat caused by development activities. Virtually all streams in urbanized areas are considered impaired.

Cities are required by TDEC to perform visual assessments of impaired streams in their communities to identify sources of impairment as well as to collect and test water samples from streams potentially impaired by activities within their jurisdictions. The primary purpose of these stream activities is to develop corrective actions to reduce or eliminate the impairment and to assess the effectiveness of the storm water program over time. Under Brentwood's storm water permit issued by TDEC, the City is required to assess all impaired streams over a five year permit cycle. A map with highlighted stream segments that will be assessed over the current permit cycle is included in the attached proposal. Also attached is an example stream observation that serves to illustrate the types of conditions noted during the assessment. The example is an actual condition noted during CEC's visual assessment of Beech Creek in 2011.

The attached storm water monitoring proposal was developed by Civil and Environmental Consultants (CEC) to insure we complete all visual assessments and sampling within the required timeframe. Our first round of assessments began in 2011, with additional stream segments assessed each year, and this year we are beginning our second round of stream assessments. As noted in Section 3.0 of the proposal, this fiscal year will include assessments and sampling of Beech, Holt and Spencer Creeks. The cost to perform the required assessment is $23,000 and adequate funds are included in the Engineering Department's operating budget.

CEC has assisted Brentwood since the inception of the City's stream assessment program and is best suited to provide the required continuing services. The attached proposal includes additional details of the tasks to be performed.

Please direct any questions to Service Center Director Mike Harris.

Staff Recommendation

Staff recommends approval of the proposed agreement with Civil & Environmental Consultant, Inc.

At the January 26, 2015 meeting the City Commission approved Resolution 2015-06 for monitoring performed in 2015. 2015 was the last year stream assessments were performed due to a delay in TDEC issuing a new storm water permit.
