S. Environmental Protection Agency (EPA) and Audubon Arkansas to fund the collection of Water Quality Data along College Branch in the City of Fayetteville to assist staff with storm water ordinance revisions in compliance with federal MS4 storm water regulations. APPROVED FOR AGENDA: -2i - os Don Marr, Alde m Date 42 27 OS David J. itaker Date Assistant City Attorney (as to form only) aye ev• l e City Council Meeting Date : ARKANSAS The City of Fayetteville, Arkansas City Council Agenda Memo To: Mayor and City Council From: Don Marr, Ward 2 City Councilor Assisted By: Melissa Terry, Audubon Society and Stephen Davis, City. of Fayetteville Date: September 27, 2005 Subject: Urban Water Quality Data Collection Funding Recommendation : Allocation of $25,000 as cost share towards $86 ,720 for water quality monitoring on College Branch , an urban tributary stream of Town Branch and the West Fork of the White River. Background : The Environmental Protection Agency has declared urban storm water run-off as one of the biggest contributors of non-point source (NPS ) pollution in streams and rives of the United States. This request comes forward from a grant awarded by the Environmental Protection Agency to Audubon Arkansas and Washington County for the purpose of stream restoration at the section of College Branch that runs through the U of A campus. This stream originates on the U of A campus and then flows into the City under 6(h street, through the Town Branch neighborhood and confluences with Town Branch just south of 15th Street. The purpose of the funds requested is to measure NPS pollution by collecting water quality data at 6`h street and 151h, testing for chemicals, bacteria and sediments within the sampled section . This data can provide the City with valuable urban stream data that can assist staff with storm water ordinance revisions and compliance with federal MS4 storm water regulations. Additionally, the data collected at these two sites will provide information regarding water quality as it leaves the U of A campus and as it flows through a residential neighborhood . All of data collected can provide elected leaders and staff with scientifically-verified information from which future NPS pollution prevention practices, policies and procedures can be measured . 113 WEST MOUNTAIN 72701 479-5758330 479-575-8257 (Fay) Additionally, flow and velocity data collected from these two sites ill help staff (particularly Parks staff) understand the rates of urban stream bank erosion and provide these staff members with information relevant to erosion prevention planning within City parks and other urban streams. Budget Impact: The City funds for this Cost-Share are budgeted in Project #02097 Drainage Study/Phase II Stormwater Management. 113 WIiST MOUNTAIN 72701 479-575-8330 479-575-8257 (riu) w w ORDINANCE NO. AN ORDINANCE WAIVING THE REQUIREMENTS OF FORMAL COMPETITIVE BIDDING AND APPROVING A COST SHARE IN THE AMOUNT OF $25,000.00 WITH THE U. S. ENVIRONMENTAL PROTECTECTION AGENCY (EPA) AND AUDUBON ARKANSAS TO FUND THE COLLECTION OF WATER QUALITY DATA ALONG COLLEGE BRANCH IN THE CITY OF FAYETTEVILLE TO ASSIST STAFF WITH STORM WATER ORDINANCE REVISIONS IN COMPLIANCE WITH FEDERAL M54 STORM WATER REGULATIONS. WHEREAS, cost-sharing with the U. S. Environmental Protection Agency (EPA) and Audubon Arkansas to fund the collection of Water Quality Data will avoid the added cost and unnecessary duplication of effort which would arise from the formal competitive bidding process, and; WHEREAS, access to such Water Quality Data will greatly assist staff with storm water ordinance revisions necessitated by federal MS4 storm water regulations. NOW, THEREFORE, BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF FAYETTEVILLE, ARKANSAS: Section 1 : That the City Council of the City of Fayetteville, Arkansas hereby determines an exceptional situation exists in which competitive bidding is deemed not feasible or practical and therefore waives the requirements of formal competitive bidding, and approves a cost share in the amount of $25,000.00 with the rU. S.

J PP,ROVE I: DAN COODY, Mayor ATTEST: By: ' S'O DRAB SMITH, City Clerk 0 0 WATER QUALITY SAMPLING OF THE COLLEGE BRANCH - A INTRODUCTION Water quality monitoring of the College Branch tributary to Town Branch creek will be conducted by the Arkansas Water Resource Center — Water Quality Lab. Monitoring will consist of grab water samples taken during base-flow conditions at four sites, stream bottom sediment samples taken near the lowest site and a data collection sonde at the lowest site. SCOPE A data sonde measuring turbidity, conductivity and temperature will be installed at the Sixth street intersection with College Branch. The sonde will be enclosed in a permanent enclosure. It will be set up to collect and store results every hour. The sonde will be installed, maintained, and calibrated by AWRC-WQL personnel . It will be calibrated once per month. Grab water samples will be collected at four sites on College Branch every two weeks during base-flow conditions. These samples will be collected by others and delivered to the WQL for analysis. The analyses performed will be alkalinity, fluoride, chloride, nitrate, phosphate, sulfate, ammonia, total suspended solids, suspended solids concentration, turbidity, total coliform and a coli. The sampling sites will be at the college branch junction with: Maple, Leroy Pond Road, the parking lot below Carlson Terrace, and Sixth Street. Once per quarter a blank and a duplicate sample will be collected at one of the sites and analyzed for all parameters. These results will be used to assure field quality control. The sampling point will be alternated so that each of the four points will have a duplicate and blank analysis associated with it. Benthic sediment samples will be collected 4 times per year near the Sixth Street sampling point. Sediment samples will be collected by others and delivered to the WQL for analysis. Analyses will consist of total aluminum, total cadmium, total sodium, total vanadium, total zinc, total nitrogen, and total phosphorus. DELIVERABLES Deliverables will consist of an annual report detailing measurement and analytical results. The report for the first year will detail the relationships between the continuous sonde data and grab sample data. These relationships will be used to estimate annual loadings for TSS and sediment (SSC). Base-flow concentrations of nutrients, sediment and bacteria will be evaluated both temporally (every 2 weeks) and spatially (four sites) for variation and sources. Sediment sample results will be evaluated for concentration of toxic materials with season variation (quarterly samples). This report will be provided at the end of the first year. A second and third annual report will be provided that details the measurement results from the sonde. Any relationships established during the first year will be continued and the results reported. All data collected will be provided with the report and quality assurance/ quality control results from the field and the lab will be provided with the data. 4 - � m e � f � R �ƒ 2 « ` ` 5M ! m # © e � m a _ : a , = , = R7 , ee ; « � _ , _ , : \ � _ _ : � & { ¥ C ` n a o Q c OF ° C �p A 00 o m 3 O A3 O w p 0 i y 05 m n m a 3, �^ n Z u n m 0 .40n W O F C n N N y m y (nn r o Mach o d .n.
