Adjournment Item 1. Call to Order Councilmember Knight called the meeting to order at 10:01 a.m. Item 2. Tower #2/ Painting & Rehabilitation (Project 07-48) Mr. Berkowitz provided an update on the status of the Tower #2 Painting and Rehab project. All cell phone antenna's currently on top of the tower will be temporarily relocated north ofthe Water Treatment Plant during the project. The project is being bid with three different timeframes as options: 1. Start March 2008; 2. Fall 2008; and 3. Spring 2009. Once the bids . come in, staff will determine which schedule to follow based upon the prices and the potential impacts on the water system as the tower will need to be off-line for approximately nine weeks to complete the project. Painting and minor repair work will take place inside and outside of the tower. During the project, a drape around the sides will extend to a height of20' above the tower . to contain dust. Full containment is not needed for this tower as it was not painted with a lead based paint. Full containment would cost an additional $25,000. Typical tower rehabs are needed every 15 years. This tower is now 17 years old. Mr. Ortell asked about the revenue generated by the cell phone towers. Mr. Kraabel said the revenue generated is approximately $30,000 per year. Item 3. Discuss Clear Well at Public Works Mr. Berkowitz described the reasons why a new clear well is needed, to meet peak demands of the system. Tower #1 is to be removed, which will convert the City to a one-tier water supply system. A key component to underground storage is high capacity pumps to maintain the ------ Public Works Committee Meeting Minutes - February 14, 2008 Page 2 pressure. A 2 million gallon clear well is needed, with approximate dimensions of 150' -175' diameter, 25' deep. The size can vary depending upon the chosen depth. Round is the most economical shape, least likely to leak. It is possible that tennis courts, or another hard surface use could be accommodated on the top of the tank. Staff is looking at a site west of the water treatment plant (WTP). This will allow a close proximity to the treatment plant and the new clear well would be tied into the existing clear well. The key at this time is to identify a location so planning can continue at the Public Works site, and so the excavated material would only need to be moved once. An access road would also be proposed on the west side of the WTP to access the clear well. Mr. Berkowitz and Mr. Kraabel discussed expansion ofthe reclaim tank at the WTP. This, as well as the clear well project, could be done at one time to save costs. Mr. Kraabel discussed the potential to use plate settlers, which, if feasible, may make expansion of the reclaim tank unnecessary. More study is being conducted on this item. Mr. Berkowitz stated that once development continues, ultimately more wells and another WTP would be needed to meet demand. The 2 MG clear well would meet the ultimate storage expected. It is possible that one well and a WTP could be located in the Shadowbrook 3rd Addition development and an additional well in the Shadowbrook East Park. The hope is that these wells would be drift wells. The City currently has one other drift well, and it is our top producing well. Test wells will be drilled this summer. Once the new wells are on-line, it is possible that wells 2 and 3 (Mt. Simon wells with radium) will no longer be needed even for peak flows. Mr. Berkowitz stated that he will bring more detailed information to a second Public Works Committee meeting ~n the fall and provide an update to the City Council once this project is further along. I ! Item 4. 3-Way Stop $igns Mr. Haas described how the sign department is working on Zones 1 and 2 in the City to update signs to meet federal requirements in the MMUTCD. Next year staff will work on Zone 4 updates. Staff is analyzing all signs within the City to determine if they were placed correctly and meet the current guidelines. Sign reflectivity is a major issue. The life span for a sign is approximately 15 years. There are several locations in the City with 3-way stops that may not meet warrants. Traffic counts will be completed to determine if the volumes justify the 3 and 4 way stops. Mr. Berkowitz stated that he wants to have neighborhood meetings to let the residents know what is happening and why the signs will be pulled (assuming they do not meet warrants). Staff will be working on GPS locations for each sign, and will prepare a City wide base map of our sign inventory. Public Works Committee Meeting Minutes - February 14, 2008 Page 3 Item 5. Discuss Future State Aid Designations Mr. Law discussed the Cities state aid system and how new mileage can be added to the system each year. Anoka County is considering turning back several County Roads to the City. Mr. Law explained how a County Road turned back to the City can be designated as an MSA route without reducing the 20% allowable mileage limitation. However, if a County Road is turned back to the City that has an MSA designation already, that route is not eligible for turnback status and that mileage would count against the City's 20% allowable mileage limitation. Mr. Law explained how the City is able to maximize our State Aid funding if County Roads are turned back to the City by removing all MSA designations from County Roads and designating local streets. Mr. Berkowitz provided a draft map from the Anoka County Transportation Plan identifying the following routes for turnback to the City by 2030: . Crosstown Boulevard (CR 18) - From 133rd Avenue to University Avenue (Designated MSAS from Andover Blvd to Hanson Blvd) . Verdin Street (CR 59) - From 161 st Avenue to 181 st Avenue (Designated MSAS from 168th Lane to 177th Avenue) . Andover 130ulevard (CR 16)- From Crosstown Blvd to University Avenue (Designatbd MSAS from Hanson Blvd to Prairie Road) . Valley Drive (CR 58) - From 7th Avenue to 181 st Avenue . 165th AV{'jnue (CR 158)- From 7th Avenue to Valley Drive . 177th A vdnue / Palm Street (CR 58) - From 181 st A venue to University Avenue I I The Committee's redommendation was to remove all MSA designations from County Roads except for a segment of Crosstown Boulevard from Nightingale Street to Hanson Boulevard as MSA funds have b1 expended npon this segment recently, and the City would have to refund a depreciated amount f these funds to MnDOT if the MSA designation was removed. Mr. Law presented a map with several potential MSA designations. A total of 3.44 miles is available for designation after the County Road revocations and including new mileage. The group consensus was to designate the following routes as MSA: MSAS No. MSAS Route tu Desi!!:nate Lemrth 1 174th Lane (Round Lake Blvd to Verdin Street) 1.00 miles 2 38th Avenue (Bunker Lake Blvd to Anoka city limits) 0.06 miles 3 Jivaro Street / 170th Avenue (165th Avenue to 7th Avenue) 1.25 miles 4 167th Avenue / 168th Avenue (University Avenue to Ward Lake Drive) ** 0.60 miles 5 Dakota Street (l57th Avenue to Valley Drive) 0.50 miles Total 3.41 mile~ Public Works Committee Meeting Minutes - February 14, 2008 Page 4 ** Requires realignment of existing MSA route east of Ward Lake Drive These routes will be presented to the City Council at the next meeting for approval. Staff needs to present our potential MSA designations toMnDOT by March 1, 2008 for their review and approval. Pending MnDOT approval, formal City Council resolutions would need to be submitted to MnDOT by May 1, 2008 for these designations to be official. Item 6. Other Business Mr. Haas provided an update regarding the proposed Skate Park at Sunshine Park. This project has $100,000 identifIed in the CIP. Current estimates for the park with concrete ramps are approximately $150,000 - $160,000. If steel ramps were used, the cost would be about $125,000 - $130,000. Mr. Haas stated that the Skateboard Task Force is recommending the concrete ramps be purchased. Pro's for the concrete are they are permanent and require a minimum amount of maintenance. Con's for concrete are they are permanent if a separate use is ever desired for the Skate Park, and cost. Pro's for the steel ramps are lower cost and they can be removed if there are problems. Con's for the steel ramps are they are noisier, hot, and their expected life is 15-20 years. Staff is meeting with! the neighbors to discuss the project. The Park Commission is meeting next Thursday, and will fqrward a recommendation to the City Council in March regarding this project. l Mr. Haas mentioned. he skate park will be fenced, and the kids tend to police themselves. If there are problems, the fence can be locked. Item 7. Adjournment Meeting adjourned at 11:47 a.m. I Respectfully Submitted, Jason Law Assistant City Engineer
