COUNCIL CHAMBERS MEMBERS PRESENT: Chairman Bud Johnson Lauren Van Roekel Ken Olson Gay Easton Dan Meats Doug Poehls Mark Mace Daniel Dart John Oakes OTHERS PRESENT: Matt Erekson Cai Cumin Larry McCann Steve Klotz Scott Murphy, Morrison-Maierle Mayor Johnson asked Cal Cumin and Steve Klotz to make comments regarding the Entryway Zoning District and the Sign Code. Cal clarified that on-premise signs are exempt from the Entryway Zoning District and recommended deleting the requirement to turn lights off at midnight. Questions had been raised regarding landscaping of parking lots and whether or not a business has to come into compliance after being sold. Cal stated that the answer is no because that is part of the zoning ordinance. The zoning ordinance has whole sections that deal with non-conforming uses. The Entryway Zoning District ordinance would not stand alone but would be part of the zoning ordinance. There was discussion regarding the requirement for 1,000 feet between signs, the need to inventory signs, lighting types, billboa?ds, the process required to amend the ordinance, the state's jurisdiction on signs, state regulation of billboards within the right of way on the interstate, the Lady Bird Johnson Highway Beautification Act, and restrictions concerning portable signs and banners. Steve Klotz explained that the Sign Code has been in process for about two years. Although the sign code has been reviewed, it has basically remained unchanged since it was written. Input from the public heatings is welcome. The sign code includes a reference to a 40-foot limit on freestanding signs that address the interstate; however, the 40-foot limit is arbitrary and could be changed. The sign code, like any other zoning code, is meant to establish a standard and a desired look for the community. The Uniform Sign Code, a subsidiary of the Uniform Building Code, is currently used to address the structure of signs. Mayor Johnson explained that the discussion of the Entryway Zoning Ordinance and the Sign Code were added to the Committee of the Whole meeting in order to claril~y some issues. The meeting would continue past 7:00 in order to have the scheduled presentation by Morrison- Maiefle. Scott Murphy, Mordson-Maierle, distributed and presented information regarding the Wastewater Facilities Plan. A copy of the information is attached to these minutes. City Council Committee of the Whole minutes of August 20, 2002 Scott explained why a Facility Plan should be done, explained the scope of a Facility Plan, and reviewed the current situation of the wastewater plant. He explained the recommended near- term improvements and the recommended, long-term improvements for the wastewater collection system. He also explained the recommended near-term improvements and the recommended long-term and population based improvements for the wastewater treatment system. Scott indicated that the trunk main replacement, the plant drain pump station replacement, the headworks upgrade, and the utility water upgrade projects would be eligible for grants. Scott explained the remaining process for the Wastewater Facilities Plan: gather City input on priorities and budget constraints; prepare and publish draft facility plan; submit report to MDEQ and hold a public hearing (scheduled for September 17); gather public and MDEQ comments and finalize report; and final council adoption of the report. Mayor Johnson thanked Scott for his presentation. The meeting adjourned at 7:29 p.m. Respectfully submitted, Cindy Allen Council Secretary ?r L ?

Review of Current Situation • Collection System - Many portions more than 90 years old - Two pump stations need rehabilitation - Significant Infiltration and Inflow during summer - Excess capacity to allow expansion is marginal • Treatment Facility - 16+ years old ($ 8-12 mil replacement value) - Secondary treatment lacks redundancy - Peak summer flows stress plant to point of near non-compliance wl permit - Miscellaneous components require short term replacement or upgrade - Population growth and regulatory changes will necessitate significant treatment change: in the future. increased Summer Flow Presents Significant Challenge to the VVWTP s 5:1 flow increase X2000 -1999 _,?-1 BBB WWTP Design • 2 Ir1 LJ Planning Period Extends For 20 Years Population Projection 20001acq 2005 2010 2015 2020 2022 • Yellowstone County 129,352 136,111 143,244 150,724 158,272 161,245 City of Laurel 6,255 6,806 7,162 7,536 7,914 8,062 @ 5% of Yellowstone Co.
