In attendance were: Village Board Staff Robert Benton, Trustee Phil Kiraly, Assistant Village Manager Thomas Jester, Trustee Robert Fialkowski, Director of Finance Harriet Rosenthal, Trustee Jeff Ryckaert, Principal Planner William Seiden, Trustee Kathy Van Ohlen, CD Secretary Barbara Struthers, Trustee Jim Bernahl, Assistant Village Engineer Brad Fink, Assistant Director of Public Works Dan Busscher, Superintendent of Streets and Utilities Frank Cisek, WRF Superintendent Kendal Dean, Administrative Intern Kent Street, Village Manager Workforce Housing – Metropolitan Planning Council Mr. Ryckaert introduced Joanna Trotter representing the Metropolitan Planning Council (MPC) who presented an introductory video outlining the value of workforce housing. She reviewed the concept of an inter-agency coalition to locate workforce housing currently being explored by Highland Park, Lake Forest, Highwood, Northbrook and Deerfield. Mr. Ryckaert reviewed several tools available to encourage workforce housing. Trustee Struthers encouraged further consideration of inclusionary zoning and expanding the region beyond the 5 communities currently considering the approach, as well as recognized the limited vacant land available for development in Deerfield. Trustee Jester noted other issues impact this discussion, including transportation facilities and tax credit availability. It was agreed that staff should prepare a report on the various tools available and their possible impact on Deerfield prior to further consideration of formally endorsing the coalition. WRF Design Study – Progress Report Mr. Bernahl introduced Randy Wirtz and Vern Witthuhn of Strand Associates to present the first progress report concerning replacement of the Wastewater Reclamation Facility (WRF). Report elements included the following: Goal of the Report History Overview Project Need and Drivers Status of the Report Results to Date Next Step and Schedule Approved 6/30/08 Page 2 of 3 Mr. Wirtz noted that the basic goal was to develop a long-term plan for the Deerfield WRF to reliably meet environmental requirements for the lowest practical cost to the rate payers. He reviewed the current service area and the development history of the current facilities. He concluded by noting the replacement project was being driven by several factors: * plant age and deficiencies; * operations and maintenance costs; * automation; * regulatory changes, including dissolved oxygen and discharge measurement; * future regulations pertaining to phosphorous and nitrogen discharge limits. Mr. Witthuhn reviewed the conditions of the current plant. Mr. Wirtz outlined various project tasks, noting that the next major steps were to identify and evaluate alternatives and develop a recommended plan. A major outcome of this study includes the conclusion that based upon minimal projected demand growth, there is no need to increase discharge limits to the Chicago River. As a result, anti-degradation analysis is not required, thereby easing the permit approval process. Other findings resulted from the current condition assessment, revealing that the existing WRF has a complicated pumping and treatment scheme, equipment and structures are deteriorating, outdated control and monitoring systems are used and some processes have inadequate capacity. Five alternative treatment designs are being considered and their evaluation will include site and system integration requirements, as well as costs for capital, operating, maintenance and a present worth analysis. Any selected alternative should significantly reduce the risk of odors and energy consumption due to the current requirement that the wastewater be pumped 3 times. An upcoming public information session will be held, inviting surrounding neighbors, prior to the next progress report to the Village Board. The project schedule was reviewed, noting it is hoped to have a submittal to the IEPA before the end of 2008, complete the detailed design and bidding in 2009, and construct the project over two construction seasons in 2010 and 2011. It was agreed that construction traffic routing and the reduction of construction impacts were important considerations. The next progress report will likely be presented by Strand to the Board in August. Sanitary Sewer Inflow and Infiltration Monitoring Report Mr. Fink introduced Cathy Morley and Jim Liubicich of the RJN Group. They provided an executive summary of their firms study results from monitoring 21 points in the sanitary system for 60 days in April and May of 2007. Wet weather peaking factors for a good system are 3.0 to 5.0, and the Village-wide system peaking factor is found to be over 10. This means that double the amount from a good system must be treated by the treatment plant or excess flow facilities. System defects which allow excess rain water into the system and results in high peaking factors can include such things as cracked pipes and joints on Village and private property, as well as Approved 6/30/08 Page 3 of 3 improperly connected storm drainage systems and sump pumps on private property. RJN recommends source identification and cost-effective removal of excess flow sources. Ms. Morley and Mr. Liubicich reviewed various program phases and priorities to reduce public and then private inflow and infiltration. Typically a long-term effort (10 years or so), this type of program requires a concerted effort to repair Village lines and inlets, as well as conduct private property inspections and follow-up to assure that the disconnection of sump pumps, gutter systems and driveway drains takes place. It was agreed that a prioritized approach should be identified for further Board consideration. Staff will work with RJN to develop a recommendation for further consideration by the Village Board. Adjournment The meeting was adjourned at 9:45 p.m. following unanimous approval of the motion to adjourn made by Trustee Jester and a second by Trustee Rosenthal.
