Opening Remarks Scott Smith called the meeting to order at 9:02 a.m., and commented on the strength of the agenda. Approval of 9/2/16 Minutes Mr. Smith asked if there were additions or corrections to the minutes of the September 2nd meeting. The minutes were approved as distributed. Wet Weather Storage Tanks – Charlie Martin Mr. Smith introduced Charlie Martin, Director of the LFUCG Division of Water Quality (DWQ). Mr. Martin shared his recent presentation to the Bluegrass Area Development District on the Wet Weather Storage (WWS) Tanks which are a part of the Remedial Measures Plans (RMPs) for Lexington’s sanitary sewer system. The RMPs are required to be complete by December 31, 2026, per our Consent Decree. The RMPs include 35 wastewater treatment plant (WWTP) projects, 74 pipeline or pump station projects, and eight wet weather storage tank locations, six of which will be completed or under construction in the next two years. These tanks are seven percent of the total number of projects, but represent 55% of the $590 M cost. Prior to developing the RMPs, DWQ assessed the entire sanitary sewer system to determine its issues and deficiencies, and then developed the RMP solutions. DWQ’s directive from the Mayor’s office was to complete the RMP projects on time, but at a cost of less than the projected price tag, which has required a robust project management effort to incorporate value engineering and to find ways to design and construct the designated projects as efficiently as possible. The first WWS tank designed and constructed was the 22 million gallon (MG) storage tank at Town Branch WWTP, estimated at $21.4 million. Mr. Martin explained how the associated 56 MGD pump station was constructed, and shared a simulation of how the WWS tanks are filled and drained based on incoming flowrates to the WWTP. Flows, which in the past would have bypassed the plant and gone directly into the receiving stream, can now be diverted into the tanks and held there until the WWTP has the capacity to treat the excess flows. The tanks are controlled by the Supervisory Control and Data Acquisition (SCADA) system. The tank was filmed by a drone during the construction phase and is available for viewing at http://www.youtube.com/watch?v=8iP3VKO1bww&sns=em. Mr. Martin also shared a time-lapse video of the Town Branch WWS tank’s construction. The Wolf Run WWS tank, with a capacity of 2 MG, complements the new 17 MGD pump station completed in 2014. Located in a residential area and visible from New Circle Road, the Wolf Run WWS tank includes a landscape berm with stone pillars and wrought iron fencing to make it more appealing to the neighborhood. The West Hickman sewershed has the most overflow locations. Numerous trunk lines have been or will be upsized to meet a 2-year, 24-hour design storm, and with construction of two new WWS tanks and the treatment plant reliability upgrades, more money will be invested in upgrading the sewer capacity, transmission, and treatment in this sewershed than in any of the others. The construction of the WWS tank at the West Hickman WWTP with its associated plant upgrades is the largest construction contract ever let by LFUCG. The Lower Cane Run WWS tank will be located next to the Legacy Trail, and will include Council-approved amenities for trail users, including a wood scrim façade, a plant berm, a restroom, a water fountain, a rest plaza, and bike racks.

The costs of the WWS tanks are on track to come in at $100 M less than originally estimated, which is a substantial savings, given the total projected RMP cost of $590 M. Mr. Smith asked if we are financing the storage tanks with bonds, and Mr. Martin replied that we have financed the tanks with Kentucky Infrastructure Authority (KIA) loans, at a 1.75% interest rate. Ken Johnson asked if our sewer user fee pays for all of this. Mr. Martin replied yes, it is all through the Sanitary Sewer Use fee, adding that there have been two 12% increases over the last two years. Scott Southall asked if we know the cost per gallon to store and treat. Mr. Martin said we have not been able to evaluate those costs yet, but that cash flow modeling is done every month. Ken Cooke asked the acreage footprint for the Wolf Run tank; Mr. Martin answered about two acres. Mr. Cooke asked if there is a plan to restore the soil, which was a floodplain, and if post-construction controls were incorporated for the runoff from the 2-acre site. Mr. Martin said he is working with a landscape architect, but he does not know the answer about post-construction controls, and will have to look into it. Michael Galavotti asked how the tanks will be cleaned and if odor control was incorporated. Mr. Martin explained that hatches provide access for cleaning, which should primarily be the removal of grit from the bottom of the tanks. He further explained that the tanks have been piped to accommodate odor control equipment, but Lexington opted not to install the equipment unless or until it is warranted as there is some debate over the actual amount of odor that could be emitted due to the diluted nature of the sewage that will fill the tanks. Mr. Johnson asked if the Capacity Assurance Program (CAP) can help predict when the tanks will be needed, and Mr. Martin replied that it can, because both the RMPs and the CAP rely on the same hydraulic model. The hydraulic model is updated as CAP projects and RMP projects are completed. Water Quality Management Fee: What Does It Fund? – Charlie Martin Mr. Martin provided a recap of the Water Quality Management Fee (WQMF) for Fiscal Years 2010 – 2016. Billing receipts have increased over time as we document and bill new impervious areas. The top five categories of expenses funded by the WQMF are Water Quality, Streets and Roads, Environmental Services, Finance, and Indirect Cost Allocation. In 2011, the first full year of the fee, 52% of the WQMF collected was expended by DWQ, and by 2016 that percentage increased to 61%. There was a large spike in 2012 in DWQ capital stormwater projects. Grant spending has also been the cause of spikes in cash flow, since some grant recipients are slower to execute grant contracts than originally anticipated. LFUCG has also seen expenses increase due to changes in how we bill the WQMF. Kentucky American originally billed city services such as sanitary sewer usage, the WQMF, and the landfill fee, but Kentucky American cancelled that agreement with LFUCG not long after the WQMF was implemented. Since then, Cincinnati Waterworks has been our billing agent, but LFUCG is working to bring billing capabilities in house via an expansion of LEXServ. Expense distribution of Indirect Cost Allocation is tied to personnel. Jennifer Carey added that while indirect costs have increased since 2015, the percentage assessed to calculate the indirect costs has actually decreased over time. Thus the increase in the Indirect Cost Allocation is due to increases in personnel. Of the $80,968,469 WQMF in revenue, we have expensed $67 M. We currently have an unrestricted WQMF Fund Balance of $9.3 M, and we have intentionally created this fund balance to spend on future capital projects. For example, five separate projects previously identified around the Southland Drive area will be combined into one single project which will be the largest stormwater project to be funded by LFUCG.

Mr. Johnson asked if Council has passed a WQMF rate increase since inception of the fee. Mr. Martin replied that other than the annual CPI increase authorized by the ordinance, that a rate increase has not been necessary. LFUCG has worked to use its resources as efficiently and effectively as possible. Southland Area Storm Drainage Project – Greg Lubeck Greg Lubeck pointed out Beacon Hill Drive on a map of the Southland Area Storm Drainage Project, and delineated five stormwater projects which were previously prioritized: Tucson Drive, Picadome, Barkley / Southgate, Longview Drive West, and Longview Drive East. Mr. Lubeck provided an estimated cost of just over $10 M for these projects. The projects will be evaluated by a consultant with the goals of reducing flooding for a target design storm, improving downstream water quality, quantifying tangential benefits, lessening sanitary sewer impacts including those caused as a result of sump pump redirections, and coordinating with other capital projects. Traffic concerns, the incorporation of green infrastructure practices, and new storm sewers to collect runoff are anticipated to be addressed by this project. Mr. Martin added that we are on the same track in other parts of town where we strive to have synergy with stormwater management and the sanitary sewer program, in other words, effectively using resources to solve two problems. Eight proposals were submitted by design consultants in response to the advertised Scope of Services and selection of a design engineer is anticipated in January 2017. Mr. Cooke asked about the modeling of the karst system in that area, and suggested a review of literature, e.g., studies by Jim Currens and Rob Blair completed in the area, and suggested inclusion of streetscaping that was a large component of the Wolf Run Watershed-Based Plan. Mr. Martin agreed that the karst system is an important part of the fact-finding component of this project. Chris Dent told the group that as part of the design effort that information from the karst studies will be incorporated in the hydraulic modeling for the project. Manufactured Treatment Devices in Lexington – Jennifer Carey Ms. Carey acknowledged that the September meeting provided a really good introduction to manufactured treatment devices (MTDs) and how those work and their effectiveness. She reminded the audience that at the conclusion of that meeting someone had asked about the prevalence of MTDs in Lexington, which leads us to today’s presentation. Our inventory of post-construction water quality best management practices (WQ BMPs) was originally compiled in 2010, and currently has 843 WQ BMPs. In 2015, Jason Martin, Pat McFadden, and Bill Warren took over responsibility for the inventory and inspections of basins, ponds, and WQ BMPs for LFUCG. Mr. Martin pointed out that we have four times as many WQ BMPs on our inventory now than we knew about when we started. Gabe Hensley asked if the increase in post-construction BMPs is tied to the Stormwater Manual. Ms. Carey explained that the engineering manuals have been in place longer than the inventory has been tracked, so we are adding to the inventory as we learn of existing WQ BMPs. Richard Walker added that the new Stormwater Manual, dated October 1, 2016, places more emphasis on green infrastructure. Mr. McFadden explained the approach for notating WQ BMP condition on the inspection forms. Inlet inserts are the most commonly used BMPs and multiple inserts are often found on a single parcel. Ms. Carey then showed photographs of a variety of MTDs in use in Lexington. Mr. Cooke asked about which units are in significant non-compliance or are failing, and Ms. Carey replied that we have the most compliance issues with inlet inserts, but that is primarily due to the fact that they comprise over two-thirds of our inventory.

2017 Meeting Dates March 3, 2017 June 2, 2017 September 1, 2017 – Friday before Labor Day December 1, 2017 The meeting dates for 2017 were approved. Nominations for Remaining Vacant Watershed At-Large Seats Boone Creek and North Elkhorn Watershed At-Large seats remain vacant. Topics for Next Meeting – 3/3/17 Ms. Carey indicated that we intend to discuss BMP Implementation to address approved TMDLs at the March meeting. Amy Sohner offered to present Bluegrass Greensource’s education efforts that are funded by LFUCG. Mr. Cooke indicated that applications for the Stormwater Quality Projects Incentive Grant Program should be available by the March meeting, so that could be a potential topic. Announcements

This project is a Supplemental Environmental Project (“SEP”) to be funded by LFUCG as part of the Consent Decree entered on January 3, 2011 styled United States & Commonwealth of Kentucky v. Lexington-Fayette Urban County Government, United States District Court for the Eastern District of Kentucky, Civil Action No. 5:06-cv-386-KSF (the “Consent Decree”).

Project Overview

Under the terms and conditions of the Consent Decree, LFUCG agreed to spend at least $30 M on specific SW flood mitigation projects by January 3, 2021.

During an April 2016 presentation to the EQ&PW Committee, Water Quality presented the spending status as:

$9.9 M spent to date for completed projects

$5.0 M budgeted for projects in process

$15.1 M remaining obligation for currently undeveloped SW flooding projects.

Water Quality recommended the development of a modified project development process, one that grouped projects in a geographic manner to increase project efficiencies.

The committee endorsed merging five (5) individual projects in the Southland Drive, Pasadena Drive, Clays Mill Road area into a single project, estimated at $10 M in total project costs.

If preliminary cost estimates hold true, completion of the project will 1) be a significant step towards meeting the total $30 M spend obligation, and 2) be the largest SW management project ever undertaken by LFUCG.

Project Overview

Milestones from 2016 Presented conceptual project approach to EQ and PW Committee and received an

endorsement to proceed.

Held an October 2016 neighborhood meeting in conjunction with CM Bledsoe’s office to kick off project.

Advertised Engineering Services Scope of Services – eight (8) proposals received. Currently in the selection phase.

Forecast for 2017 Selection of design engineer – January 2017

Customer survey methodology will be implemented for over 5,000 impacted properties. Goal is to gain customer input on chronic flooding issues so that solutions can be developed and vetted for implementation.

Data collection for hydraulic model likely to begin in spring so that wetter part of a typical year is captured. Field installed rain gauges and stream gauges will be the data collection method.

Field survey work will likely go on through summer and fall. System geometry needed to calibrate a hydraulic model for use during the analysis phase.
