Berkowitz, City Engineer TO: FRO:\1: SUBJECT: Review of Water System Capital Improvement Plan - FinancelEngineering DATE: November 9, 2004 INTFODUCTION On May 25, 2004, the City Council authorized Short Elliott Hendrickson (SEH) to update the Wellhead Protection Plan, update the City's hydraulic distribution water model and also evaluate , '\ the water system for improvements required to provide adequate water supply to the City for the '-/ next jve years. DISCUSSION A Wellhead Protection Plan is required by all municipalities that supply potable water. The Minnesota Department of Health originally required the City of Andover to complete the plan by the end of 2004. The need for another well within two years and the plan to update all wells has extended the completion for the plan to 2006. This Wellhead Protection Plan will include all the existing wells and proposed Well #9. Upda ting the hydraulic distribution model has assisted staff in determining existing fire flow prote';tion and needed improvements relative to new development. This model should be updated annwJly. The main point of discussion is for the proposed water system improvements needed to provide adeql:ate water supply to the residents of Andover. There are three main projects that SEH reconnnends in the 2004 Water System Improvements Plan. ~-) The lirst improvement, which would be constructed in 2005, would be the drilling of a new municipal well (Well #9) at the comer of Andover Boulevard NW and Xeon Street NW. The property is owned by the City and has been included in previous water studies as the next well site. A pitless unit submersible well and the transmission line which would be extended from this locati:m to Well #8 would be constructed in 2006. By constructing the distribution line, the well would be tied directly into the Water Treatment Plant providing additional treated water for consumption, The cost to complete the two year project is estimated at $1,256,000 (see Table 1 on pgs. c, & 5 in the draft plan). This is a much more feasible option than constructing a treatment plant lt the wellhead, which is estimated at over $3,000,000, , " . , Mayur and Council Members Nove'Ylber 9,2004 Page 20f2 The ;econd improvement would be to construct a two million gallon water tower on the City Public Works site near the Water Treatment Plant. This would provide adequate water supply stora:~e volumes for the maximum day water demands and fire flow projected through the year 2020, There are economies of scale to construct a larger water tower than to construct several towers that would equate to the same storage volume. By constructing this tower the 500,000 gallol tower on the west side of Andover could be removed, creating a one system pressure zone. The Jenefits of a one pressure zone are explained in the attached draft 2004 Water System Improvement Plan and will be discussed in detail. The estimated cost to construct a two million gallo:l water tower and demo the existing 500,000 gallon tower is $3,123,000 (see Table I on pgs, 4 & 5 in the draft report). -, '---.' The third improvement (2009) would include constructing a 12 inch water main down South Coon Creel: Drive NW from Crosstown Boulevard NW to Round Lake Boulevard NW. This extension would provide another connection point (at this point there is only one connection between the two systems) and provide increase fire flows to the southwest section of the City. In the future this line will also be needed to supply adequate water to the Rural Reserve Area. The estimated cost to extend the water main down South Coon Creek Drive NW is $468,000 (see Table I on pgs. 4 & 5 in the draft plan). Attached is a draft copy of the 2004 Water System Improvement Plan for your review. SEH along with :;taff will present information in the report to be discussed at the meeting. BUD3ET IMPACT The proposed improvements would be funded by a combination of the Trunk Water Fund and Wate: Revenue Bonds. ACTJON REOUIRED The City Council is requested to discuss presented information and direct staff on how to proceed with the proposed water system improvements. Once the direction is clear the 2004 Water System Improvement Plan will be brought back to the Council for approval. Respc:ctfully submitted, . Davie! D.

WWW,CI.ANDOVER,MN,US TO: Mayor and Councilmembers Jim Dickinson, City Administrat~ Will Neumeister, Community Development Director!~ David Berkowitz, City Engineer CC: FROM: SUBJECT: Road Improvement/Funding Policies--Planning DATE: November 9, 2004 IN1 RODUCTION For background, attached is a report that was presented in April of this year along with the minutes from the Council workshop where this was previously discussed, The Council made it cI ear at that time improvements to the transportation system need to be planned and paid for by utilizing three potential funding sources: . Assessments . Tax Levy . Developer Proportionately Making Payments As new demands on the City and County road network require upgrades to intersections and wid :ning of roads, the City and County need to make plans to allocate adequate resources to allo N transportation issues to be taken care of before they build up to a level of service that is con,;idered unacceptable, This report will attempt to explain the issues that arise and explain how City staff would recommend establishing new policies to achieve the desired effects. DISCUSSION The matrix on the following page will be put up on the white board when we are discussing this issue, Council will be asked to address how they feel these needed roadway imp:ovements will be paid fOL For example, if improvements are needed on the road syst :m, will the City require the developer to pay for these improvements or will the City incr:ase the general tax levy to pay for it, or will it be assessed. To better plan for the needed imp 'ovements, staff needs to know the appropriate levels of contribution from each funding source, If the Council would like to offer a qualified yes on a given improvement, that is aCCf ptable, Staffs desire is to get Council's opinion and clear direction on this complicated issu:, () Road Type Responsi!Jle Commercial Residential For Cost! A- B- A- B- Local Collector Minor Minor Local Collector Minor Minor Arterial Arterial Arterial Arterial Develooer General Tax Levv Assessmelts The table above will be discussed at the workshop, Before the workshop, please think about where the financial responsibility should faiL Again, the staff will be looking for yes, no, or a qualified answer for each box in the table. Development Pays a Proportionate Amount As new development is approved, the City and/or the County typically require the County road improvement be made at the time of construction or a permit will not be issued, In the past few o years, the County was making recommendations that a given plat be approved subject to required intersectior, turn lanes or shoulder improvements on the County roadway. As a part of the plat approvals, the City calculated the proportionate amount that was attributable to the development and the developer was required to pay as a part of the plat approval, or in some cases make the entire improvement on their own. This will likely continue to be recommended for future developments where there are specific needed improvements and can be sustained (with a nexus test). To take this one step further, there are sections of new roadway in the City that are collector or arterial roa,ls that are not contained within a given plat that may also need to be expanded/improved and should the funding be looked at in the same way? For example, a road that is outside the plat that is greatly affected by the new development may need to be upgraded or improved, One situation th it comes to mind is the intersection of Crosstown and Nightingale that is affected by all the latest increases in traffic caused by the Woodland Estates developments. Capital Improvement Plans The City plans for their portion of major future roadway improvements in the Capital Improvement Plan (CIP). The County also uses their CIP to plan for where their transportation dollars will be spent on the County roadway system. There are a nwnber of improvements that show up in the County pla:l as "unfunded" and makes it rather difficult to determine if or when there will be any improveme It to a road that needs upgrading. The demands are greater than the available money and they continually work at prioritizing where their money will be spent (j FederalGl~ntApplications U Staff had recommended participation in joint grant applications with the County for Federal Grant funds (Le, HES or ISTEA grants), At the last Council workshop on this topic, Council authorized staff to begin working with the County on this, and at the last Council meeting, staff brought the issue to Cc,uncil to formally approve working with the County on the grant application for Hanson Boulevard and Crosstown Boulevard. This makes a great deal of sense as there will need to be significant upgrades of this roadway over the coming decade and both the City and County could benefit if g rants could be obtained to aid in the funding for the needed improvements. If the grant application is successful, the soonest funding would be available is 2009. The next application round is August of2005, and we will be working diligently to make sure Hanson Boulevard ranks as high as possible. These federal funds will be available for construction projects in the years of2009- 2010. Ag~ncies have the option to advance fund these projects after the federal funding for a selected project has been granted. Andover needs to continue positioning this city in the public arena to gain favor to be a Federal grant recipient. '[bere are recent examples of how cooperation between the City and County can produce great results. For example, look at Andover and Hanson Boulevard, At that intersection, there was an identified proven need with economical identified solutions and with all levels of govemment involved, a solution was identified and is now being put into action. Another recent example can be found at Prairie Road and Bunker Lake Boulevard. Once again, the cooperation of City and County produced an outcome that was very positive and was completed far sooner than originally believed possible. o Intersectio.1 Improvements The City st llf have identified and prioritized a list of intersections in the City that will need funding assistance, much like Andover Boulevard and Hanson did a few weeks ago, We have identified the following ] ist of intersections that will need to be put on a priority list and should be routinely examined tJ ascertain whether the improvements are needed in the short term (1-5 years) or longer term (6-1 0 years), Staff have ranked them in order of importance and needs: I, Andover/Hanson Boulevard (temporary signal now funded by the County) 2. 139th Avenue/ Hanson Boulevard (planned to befunded by the construction in Andover Station North by 2006) 3, CrosstownlNightingale (1-5 years) 4, 133'd Avenue/Hanson Boulevard (1-5 years) 5. I 54th Avenue/Hanson Boulevard (1-5 years) 6, South Coon Creek Drive/Round Lake Boulevard (1-5 years) 7. l6lst Avenue/Hanson Boulevard (5-10 years) 8, l6lst Avenue/Crosstown Boulevard (5-10 years) 9, Prairie Road and Crosstown Boulevard (5-10 years) Each inters ~ction needs various upgrades to be fully signalized. Intersection upgrades can range in cost from around $200,000 to $750,000 or more per intersection, As a percent of new growth, the amount that can safely be eannarked for allocation into a fund to handle these improvements is U around 1% of the new growth (equating to rougWy about $200,000 per year). Under the current policies there will be intersections that will need upgrading and there won't be any funding r "- o available. It will be a repeat of the Andover Boulevard intersection situation multiplied many times over. If OIl!" grant application for Hanson Boulevard is successful, then many of these will be taken care ofwif1 the federal funding and 20 percent paid for by Andover and the County. The chances of achieving a successful grant on the first try are not great, but it is something which we must pursue each year lntil we are successful. If we were to become successful, that would reduce our needs list to only th-ee that are unfunded (Crosstown/Nightingale, South Coon Creek Drive/Round Lake Boulevard, 161 51 Avenue/Crosstown Boulevard), Hanson will continue to be the main corridor for most of Andover's new growth. As time goes on, the safety and drive time at the various intersections on the list will continue to get worse. It may sound like a broken record, but we need to continue to lobby the County to allocate more towards intersection upgrades, Railroad Bridges and Road Crossing Improvements Another area of fiscal concern for the future will be the projected railroad bridge crossings and intersections that will likely need to be upgraded over time. The amount of train horn blowing will likely conti nue to increase with the new federal rules. The growing train traffic, population and the potential 0 f a commuter rail line could add to additional delays at railroad crossings in the City. Without pI mning for the construction of these improvements over the next decade, we will once again be fi ~ting a losing battle to find the dollars to construct the needed improvements, Staff is asking the Council to acknowledge whether or not these types of projects are to be integrated into our future planning. AssessingIor Mill and Overlay Projects o An option:or the Council to consider is assessing at least a portion of the mill and overlay projects that are done each year. For example, if the City would have assessed 20 percent of the street reconstrucfon this year, the road and bridge fund would have saved approximately $126,000 in 2004 and approximately $100,000 annually. These dollars could be used for projects that impact the City as a whok Summary The staff has described various options that are available, The Council may want to consider requiring d ~velopers to make proportionate payment for certain roadway improvements, raising the tax levy, a:Id assessing a portion of the annual mill and overlay work Together these measures could genellte significant money for city-wide projects important to the overall quality of life of Andover re ,idents. ACTION REQUESTED Council is [csked to once again review the information and discuss what methods and policies will be employed to fund the future roadway and intersection needs in Andover.

As part of my research an intema1 and external equity comparisons was done of all salaries, union and non-union. For the extema1 comparisons cities of comparable size and location were used, using Stanton Group 5 (over 25,000 population) and Stanton Group 6 (under 25,000 over 10,00 J) data, and speaking with the cities of Anoka, Ramsey, Ham Lake, Blaine and Coon Rapids. DISCUSSION r ') \..J In 20')4 the City of Andover only gave a 1% increase in January and another I % increase in July. The avera~e COLA for Stanton 5 & 6 cities was 3%; therefore many positions for 2004 were below the comp !fable market rate, With the COLA proposed at 4% for 2005, which is above the 3% predicted by Stanton 5 & 6 cities, many positions that may have been below for the 2004 market survey will now be comp uable to other cities, however there are some positions that still need adjustments, When comparing salaries internally, I looked at similar duties within departments and across the city. One r osition that stood out as being paid less than any other position in the City is the Natural Resources Tecluician position, This position is currently paid less than the receptionist and general clerk positions, and nquires a high degree of technical knowledge and skill. I spoke with City Engineer David Berkowitz and a ler reviewing the duties required of the Natural Resources Technician, we agreed that this position should be compared to that of an Entry Level Engineering Technician position, Many of the duties requited for the Natural Resources Technician are technical in nature and require considerable technical know:edge and skill consistent with that of an Entry Level Engineering Technician. Therefore, one marh t rate adjustment to be recommended is changing the Step structure of the Natural Resources Techr ician position to that similar to an Engineering Technician I. Over 50% of the current job duties are engin',ering related, therefore this would be a ood com arison. The new ro osed st system would be: Current Proposed Jul-04 Jan-05 Maximums 33 290 42135 1 26,299 35,411 Pro osed 0 2 27,298 36,756 3 '0 28,297 38,100 4 29,295 39,445 5 30,294 40,790 6 31,293 42,135 / " '-..J r-' "-) This; s based on a comparison of salaries in other Stanton Group 5 & 6 cities, In the 2004 Stanton Salary Surv<y the average Range minimum is $36,940.80 for Group 5 and $37,585,60 for Group 6, for an Engireering Technician L The changing of the Steps for this position would result in a 20% increase in the st uting wage for the Natural Resources Technician position, which would then make it comparable to other cities and be more internally equitable. Due to the uniqueness of this position 1 was unable to get a solid ~omparison from other cities other than the Engineering Technician L Another position that needs a market rate adjustment due to internal and external equity is that of the City Clerk position. The City Clerk is a department head position with responsibilities for elections, licenses, asses:;ments, data practices and official records, In addition this position will now be responsible for all of the City's imaging. The current maximum salary for this position is $56,075 annually. The average salary of individuals currently in this position Group 5 cities is $63,668 annually. The average salary of indiv;duals currently in this position for Group 6 cities is $59,675 annually. The range maximums for both Group 5 and Group 6 cities are higher. 1 propose adding a step, thereby increasing the current maximum range for this position by 3% to $60,067 annually (this includes the proposed 4% COLA adjust for 2('05), Current Proposed Jul-04 Jan-05 Maximums $ 56 075 $ 60 067 SteD 1 47,664 49,570 Stel'l2 49,346 51,320 Stel'l3 51,028 53,069 Stel'l4 52,710 54,819 Stel'l5 54,393 56,568 SteD 6 ""56,075 58,318 SteD 7 60,067 ProDosed The Planner position is another position that should be adjusted due to internal equity and market compmson. Currently the Planning Department has three levels: Associate Planner (entry level), City Planner, and Community Development Director- Due to the nature of work the City Planner currently perfonns, 1 recommend that the structure be changed to include a Senior Planner. The Senior Planner is a non-s lpervisor planning position responsible for developing, coordinating and communicating broad aspec:s of community planning for a government unit. This is a similar structure to other departments that I:ave different levels of positions such as Engineering or Accounting. In the 2004 Stanton Salary Survey the average Range minimum is $52,395 for Group 5 and $49,524 for Group 6 for a Senior Planner, The average Range rnaximum is $65,790 for Group 5 and $62,171 for Group 6, 1 propose addin ~ a Senior Planner classification and adding 3% to the current maximum salary and have that as the Step l salary of $58,158 annually (this includes the proposed 4% COLA adjust for 2005).

This report will attempt to explain the issues that arise and explain how the City staJfwould recommend establishing new policy to allow the City to charge developers for their pre-rated share, DIscm:SION Three dl:partments have collaborated in preparing this report to the Council. Therefore it will attempt to explain the collective view of these departments, City staff have done a survey of surrounlling communities in Anoka County and that information is attached, The survey found that no cities in Anoka County currently have a "Trunk Road Fee". Some cities indicated that when a plat is being reviewed, they determine what improvements are required and either make the devdoper construct the improvement, or establish what the cost would be, and let the develop ~r make a payment in lieu of making the improvement, The City Attorney's Office was consulted on the legal aspects of establishing a "Trunk Road Fee" as was talked about at a previous workshop. The City Attorney will be present at the workshop to provide comment and advice, They have completed research on the establishment of "imract fees" since some communities have tried that approach (see attached Supreme Court d:eision, case of Country Joe v. City of Eagan. The Court concluded that the connection charge was an unlawful talC Some of the discussion from the Court case gives us some directiol on how to properly establish a "Trunk Road Fee". The funding of needed roadway improvements was seen by the Court as something that cities can assess. The assessment process is one of three ways (absent State and Federal funding) that the City can try to pay for the needed improvements. The three ways would be to levy enough taxes, assess the benefiting property, or possibly create a "Trunk Road Fee". If there is no SUpP)rt for the latter option then the City is left with the first two to choose from. We will try to briefly explain what a "Trunk Road Fee" is and how it would be used. First, staff fe, Is that a detailed study of what improvements are needed (both in the short term and the ultimate design) should be conducted, similar to the City's park dedication study. Then, when developments came in for approval that require upgrades to the trunk roads, then the City could charge a "Trunk Road" fee. That money would be used to fund both the short term needed roadway improvements as well as a portion of the long term improvements. To be able to do this, both the detailed study and then appropriate accounting of the collected money would ~)e needed. That being said, the "nexus test" would be able to be met, which is ultimatdy what the Courts look for to sustain whether this is a fee that a City can charge, It is important to note that the collected money would not be co-mingled with other money of the City, Then as these improvements came forward, the "Trunk Road Fee" money would be used to payOor the specific improvements that were identified as being needed as outlined in the aforementioned detailed study. Having new developments pay for all or even a portion of the needed roadway improvements has been hampered by a lack of a City policy and/or an ordinance that establishes this as a develorment requirement. Such an ordinance would need to indicate that roadway improv~ments that are directly attributable to the new traffic from the development must be paid for by the new development (on a proportionate basis). ' Each Development Pays for Needed Roadway Improvements If the Council is not comfortable with the concepts outlined above and raising taxes, the remairing option is to make the new development pay for all needed roadway improvements at the tim ~ of plat recording. A report and resolution would need to indicate that a requirement of approv,u would be that either the developer must make the necessary improvements or an amount equal to the cost of the improvements be paid prior to the release of the plat for recordi Jg, This method is utilized in neighboring cities and seems to work. In this option, the city ag ain needs to account for money in a fund that will be used only for the specific improvement project when ultimately built. The improvement may not be done right away as other few developments will need to come forward before there is enough money collected and the project is formally authorized by either the City or County. In some cases, the County may rquire the improvement be made at the time of construction or a County permit may not be issu ~d. Capita r Improvement Plans / Grant Applications The City plans for their portion of major future roadway improvements in the Capital ImprO\ement Plan (CIP). The County also uses their CIP to plan for where the dollars will be spent c n the County roadway system. There are a number of improvements that show up in the County plan as "unfunded" and that makes it rather difficult to determine if or when there will be any improvement to a road that needs upgrading, The demands are greater than the availat Ie money and they continually work at prioritizing where their money will be spent, Staff would recommend participation in joint grant applications with the County for Federal Grant ;imds (Le. HES or ISTEA grants). This would be mutually beneficial and help get new roadway improvements sooner than they would otherwise occur. An example of this would be the section of Hanson Boulevard between Bunker and Andover Boulevards, There will need to -2. - be significant upgrades of this roadway over the next few years and both the City and County could b<nefit if grants could be obtained to aid in the funding for the needed improvements. It is imj:ortant to identify projects in the County's CIP or any publicly adopted plans to assist in the federal funding approval. County funds are used to offset portions of projects that are not covered by federal funds. The next application round is August of 2005.

ACTIO"\) REOUESTED Council is asked to review the information and discuss whether there is a need to establish either al ordinance or a policy that would create a "Trunk Road Fee". Also, discuss whether the City staff should be working with the County on joint grant applications for roadways like Hanson Boulevard or Crosstown Boulevard. David D.

Mr, Dickinson stated the need to discuss a road improvement policy for the City is becoming ever more important as new demands on the city and county road network require upgrades to int"rsections and widening of roads. He summarized the issues that would arise and explained how Cit y staff would recommend establishing new policy to allow the City to charge developers for their pre-rated share, He noted the City plans for their portion of ml!ior future roadway improvements in the Capital Improvement Plan (CIP). The County also uses their ClP to plan where the dollars would be spent on the County roadway system, There are a number of improvements that show up in the County pial as "unfunded" and that makes it rather difficult to determine if or when there will be any improvement to a road that needs upgrading, The demands are greater than the available money and they continually work at prioritizing where their money would be spent- He indicated staff would rec )mmend participating in joint grant applications with the County for Federal Grant Funds. Co'mcilmember Orttel agreed with applying for the grant- COllncilmember Trude stated she also supported the grant request. COllncil reached the consensus to participate in the grant process. Sp. cial Andover City Council Workshop Meeting Millutes - April 27, 2004 Page 5 CO'IncH made various suggestions and alternatives regarding assessments, tax: levy and developer costs, including making the improvements and deferring the cost until the land is developed, infill cor centration with a trigger mechanism, and setting up zones within the City, Co Incilmember Jacobson noted they also need to have the County put funds toward the County ROlds, Mr. Dickinson stated staffwould focus the policies on assessments, tax: levy, and developer costs, as we 'I as County contributions, CO'Incilmember Jacobson requested staff to have the City attorney review any drafted policies befJre they come back to the Council. DI;;CUSS NEW STANDARD STREET SECTION, CONT.

Study the technical feasibility of increasing the City's water supply and treatment capacity by constmcting a new well, controls, and transmission main from the well to the water treatment plant. 2, Study water supply options for serving the entire City with drinking water that complies with the Environmental Protection Agency (EPA) drinking water standards with respect to radium and gross alpha contaminants detected at Wells 2 and 3, 3, Update the City's hydraulic water distribution model with recent additions to the water system, 4. Study the technical feasibility of creating a single pressure zone where all customers receive treated water from the water treatment plant during peak water demands, 1.2 Water Supply and Treatment Capacity I. The capacity of the City's water treatment plant exceeds the capacity of the wells that are pumped to the plant by approximately 1,400 gallons per minute (gpm), The construction of a new well (Well 9), electricai controls and transmission main is needed to utilize the full capacity of the water treatment plant and meet the City's water demands for the next five years, Pumping this well to the water treatment plant would cost approximately $2 million less compared to constmcting a new water treatment plant at the well site, 2, A test well (Test Well 6) was drilled at the northeast intersection of Andover Boulevard and Xeon Street in Febmary 1997, Test resuits A-ANDOV0405,OO Page 1 ..., w ..., u ..., LJ '"' I LJ ...,. i LJ ., LJ ..., .J ..., u ~ , l.J n , u ""\ l.J ,.., u M LJ n , t,..J ,.,. l.) .., L..I "'r , LJ ~1 J n LJ 1.5 1.3 indicate that a new municipal well (Well 9) constructed at this site should be capable of pumping approximately 1,200 gpm, 3, Before bidding documents are prepared for Well 9, a well siting study should be conducted to address well siting criteria established by various government agencies, identify potential contaminant sources, and identify existing wells that may affect or be affected by the new well. Water Quality Issues (Wells 2 and 3) I, Wells 2 and 3 pump non-treated water directly into the water distribution system during peak water demands, Radium and gross alpha have been detected in concentrations that exceed the maximum contaminant levels (MCLs) that are enforced by the Minnesota Department of Health (MDH), 2, SEH and City Staff met with the MDH to discuss the future treatment requirements for Wells 2 and 3 in order to comply with the radium and gross alpha drinking water standards, The MDH, in conjunction with the EPA, will allow public water systems such as Andover to utilize a new method for measuring radium and gross alpha concentrations in the distribution system versus at the wellhead where higher concentrations of radium and gross alpha are detected, This method will allow the non- treated water from Wells 2 and 3 to be blended with treated water from the water treatment plant prior to sampling to determine the radium and gross alpha concentrations, Individual treatment plants will not be required at Wells 2 and 3 with this method, 3, A written proposal would need to be submitted to the MDH to use the new method for measuring radium and gross alpha concentrations in the distribution system, The MDH would then prepare an agreement that would allow the City of Andover to use this method, 1.4 Water Distribution System Model Update I. The City's existing water distribution system is illustrated on Figure I. The City's water distribution system model was updated with recent improvements to the water distribution system, WaterCAD (version 5,0) by Haestad Methods was the computer software used for this analysis, This update assists in planning for new development areas and identifies inefficiencies that may exist in the system. 2. Average day water pressures are depicted by pressure contours in Figure 2, The existing system pressures range from 55 to 77 pounds per square inch (psi) for an average day demand scenario. 3, The computed fire nows for the current distribution system are represented in Figure 3, The existing system pressures and fire nows were determined to be adequate, Combined Single Pressure Zone Analysis I. The Andover water system includes a low pressure zone and a high pressure zone as identified on Figure 1. The one million gallon water tower provides water storage and pressure for the high pressure zone. The high pressure zone receives mostly treated water from the water treatment pian!. Well 3 pumps non-treated water directiy into the high 2004 WeIer Systems Improvements City of A ldover, Minnesota A-ANDOV0405,OO Page 2 ., Li n L.J n , u ,.., I L.J ~ , L.J n I L.J n J r', L.J n u r-1 L.J !', v ..., I L.J .., , u ,..., L..J n d M L.J rt U "'" I.J n L.J pressure zone during peak water demands, The 500,000 gallon water tower provides water storage and pressure for the low pressure zone, The low pressure zone receives treated water from the high pressure zone during non-peak water demands, Well 2 provides the majority of water for the low pressure zone during peak water demands so customers located on the iow pressure zone receive mostly non-treated water during peak water demands, 2, The City's two pressure zone system requires additional operation and maintenance compared to a single pressure zone system. The pressure reducing station and controls must be carefully monitored by City Staff and requires periodic adjustments and repairs, 3, A single pressure zone was modeled without the 500,000 gallon water tower and pressure reducing station to determine the expected average day water pressures and maximum day fire flows, The average day pressures are depicted in Figure 4, The maximum day fire flows with a single pressure zone are depicted in Figure 5, The low pressure zone would receive adequate fire flows for the residential development. A single pressure zone would: a improve the water quality for customers that are currently located in the low pressure zone during peak water demands; b eiiminate pressure spikes caused by the altitude valve station which has resulted in damaged plumbing systems; c increase the water pressure for customers located in the low pressure zone and; d eliminate the operation and maintenance that is currently required for the two pressure zone system. 4, The existing 500,000 gallon water tower that serves the low pressure zone would need to be replaced with a new water tower located near the water treatment plant (see Figure 8), This tower location would provide hydraulic balance in the distribution system to allow both water towers to be filled to their full capacities, 5, The projected calculatcd storage need in Year 2020 for a projected popUlation of 33,000 peopie on City water is approximately 3 million gallons which also assumes the water treatment plant will be expanded in the future, A two million gallon capacity water tower in addition to the existing one million gallon water tower would provide the City with adequate storage capacity for the maximum day water demands and fire tlows through Year 2020. Constructing a larger two million gallon water tower would be more cost effective compared to constmcting multiple water towers with less capacity in the near future, 6, Figures 6 and 7 depict the average day water pressures and fire flows with the constmction of 12-inch water main along Coon Creek Drive, This water main is recommended to provide water main looping and increased fire flows to the southwestern area of the City, The water main will also providc a tmnk water main to serve the Rural Reserve Area deveiopment located along South Coon Creck Drive, 2004 We. ter Systems Improvements City of A ldover, Minnesota A-ANDOV040S,OO Page 3 n u n u n ~ ,...., u n I U t1 <..J n J '1 t..J ,..,.

Construct a 2 million gallon water tower near the water treatment plant where shown on Figure 8 to supply adequate storage voiumes for the maximum day water demands and fire nows projected through Year 2020 (see Appendix for water storage calculations), 8. Combine the low and high pressure zones into a single pressure zone to improve water quality for all clIstomers, eliminate pressure spikes, increase water pressure in the area that is currently the low pressure zone, and eliminate the maintenance required for the two pressure zone system, Opinion of Probable Construction Costs Table 1 Opinion of Probable Costs for Improvements Opinion of Item Probable Cost 1 We!! 9 Siting Study $5.000 Construct We!! 9 $170,000 2 Engineering, Legal.

Water Supply and Treatment Capacity The capacity of the City's water treatment plant exceeds the capacity of the wells that are pumped directly to the water treatment plant by approximately 1,400 gpm, The construction of a new well (Well 9), electrical controls and transmission main is needed to utilize the full capacity of the water treatment plant and meet the City's water demands for the next five years, A test (Test Well 6) was drilled at the northeast intersection of Andover Boulevard and Xeon Street in Febmary 1997, The test well was driiled to a depth of 268 feet into sand and gravel glaciai drift material. Correspondence from the well driller, E,H, Renner & Sons, recommends constmcting Well 9 with a 24-inch outer casing, 18-inch inner casing, and a 12-inch stainless steel screen installed in the sand and gravel formation. A permanent pump with a capacity of 1,200 gpm was recommended by E,H, Renner & Sons, Based upon the limited pumping data available for the test well, Well No, 9 does not appear capabie of pumping beyond a rate of 1,200 gpm. A second pumping test conducted during the construction of \Vell 9 will provide representative pumping data to determine the capacity of the well. A weil siting study should be conducted prior to constmction of the well to address the following requirements for a new well: I. Government Involvement The location and design of the proposed well must be approved by various local and state government agencies and regulators. To reduce project surprises, it is imperative to contact and involve these agencies early in the 2004 Wa er Systems Improvements City of AI Idover, Minnesota A-ANDOV0405,OO Page 5 ,.., .J ,.., u ,.., J n I L.J 1 u ,.., L.J ,.., u '1 J '1 J "i L.J "', L.J '1 u ., LJ "'1 L.J ,.., L.) ,.., U ,.., , u ~, U ,.., J process, Typically, regulators will require their own site inspection and will request to review the infonnation obtained from the tasks discussed below, Plans and specifications for test wells and high-capacity, production wells are required to be submitted to and approved by regulatory agencies, Government regulators will base their approval of a new well on whether the location and construction design meet the various local and state laws, ordinances, statutes, rules, and requirements, It is important to have detailed knowledge and understanding of these laws and regulations, 2. Potential Contaminant Source Inventory The inventory shouid include available data from state agencies (e,g, WDNR and MPCA websites) and an inexpensive, formal file search and review through subcontracting finns such as EDR, Inc, or FirstSearch Inc, The inventory should provide information regarding all properties, facilities, and sites that have documented environmentai contamination (especially groundwater contamination), or the potential for environmental contamination, Review of the subcontractor's report by local officials should be performed to ensure the accuracy of the identified sites and their ownership, 3. Site Reconnaissance Site reconnaissance should be completed to assess and evaluate the proposed well location for separation/isolation distance violations regarding applicable state laws pertaining to pollutant sources near the well, In addition, drill rig accessibility should be evaluated and potential well interference assessed, 4. Well Inventory A well inventory should be completed to identify wells that may hydrogeologicalIy affect or be affected by the new well. The purpose of this task is to evaluate the likelihood and magnitude of potential well interference, State databases are typically available to compile and catalog existing wells, Interviews with locai well drilling finns may also provide additional information, 5. Groundwater Flow l\Iodelin~ Using an existing computer grounJwater flow model. or developing a new model, can provide estimates regarding the extent and magnitude of the proposed wells capture zone and cone of depression over time, Groundwater- surface water interaction and intluence can also be simuiated and assessed using computer models, Well interference can aiso be evaluated through this task, and the model can be used in the future for wellhead protection purposes, Groundwater tlow modeling software and expertise currently available through SEH include: ModFlow, Aqtesolv@, QuickFlow@, FLOWPATH@,andMLAEM@, Figure No, 8 shows the proposed routing of a 12-inch transmission main from proposed Well 9 to an existing transmission main that terminates at Well 8, The segment of transmission main located along Andover Boulevard couid be constmcted with open trench method and ductile iron pipe, The segment of transmission main located along Hanson Boulevard may require horizontal directional boring method with high density polyethylene pipe to 2004 Wa er Systems Improvements City of Ar,dover, Minnesota A,ANDOV0405,OO Page 6 ,.., .J ,.., u n u n , u n I U n u '1 u n i ..; J ,., u ~ U '1 LJ n LJ r'I, l,.J n J n U n , o...i ,., l,.J ,.., u avoid construction conflicts and disruptions to the existing electrical power lines located along Hanson Boulevard, The final segment of transmission main located under Hanson Boulevard will require jack boring method with steel casing pipe and ductile iron pipe to avoid disruptions to the Hanson Boulevard traffic, 3.0 Water Quality Issues (Wells 2 and 3) The City maintains eight water production wells (see Figure I), Wells I and 2 supply water for the low pressure zone during high water demands, Well I is no longer used due to sand pumping problems, When City-wide water demands are high enough during the summer months, Well 2 is needed to provide the majority of the water demand for the low pressure zone, As a result, customers located in the low pressure zone receive less treated water compared to customers iocated in the high pressure zone, Wells 3, 4, 5, 6, 7, and 8 supply water for the high pressure zone during normal operating conditions, All of these wells. except Well 3, are pumped directly to the water treatment plant. Wells 2 and 3 produce water with concentrations of radium and gross alpha that exceed the maximum contaminant levels (MCLs) enforced by the Minnesota Department of Heaith as summarized on Table (2) below: Table 2 Radium and Gross Alpha Concentrations Well 2 Well 3 Maximum Concentration Concentration Contaminant (pC ilL) (pCilL) Level (MCL) (oCi/L) Combined Radium 12,~ 7,~ 5.4 226 and 228 Gross Aloha 27,9 17,0 15.4 SEH and City Staff met with the Minnesota Department of Health to discuss the future treatment requirements for Wells 2 and 3 in order to comply with the radium and gross alpha drinking water standards, The MDH, in conjunction with the EP A, will allow public water systems such as Andover to utilize a new method for measuring radium and gross aipha concentrations in the distribution system versus at the wellhead, The first step includes calculating the annual average concentrations of radium and gross alpha at the first entry point in the distribution system located near Wells 2 and 3, The average radium and gross alpha concentrations from four consecutive quarterly samples would be used, As the next step, the MDH would calcuiate the maximum amount of water that could be pumped from Wells 2 and 3 before the weighted average concentrations of radium and gross alpha would exceed the MCLs, Treatment for radium and gross alpha would not be required as iong as the weighted uv.eragc concentration does not exceed the maximum contaminant level established for the contaminant. This method is intended only for water 2004 Wa-er Systems Improvements City of Ar dover, Minnesota A-ANOQV040S,OO Page 7 ,.., J ,.., u .., I U ,., .J ,..., , u n I L.J .., I u ,., I J ,..., I U ,.., , LJ ...., u '1 u .., I U ,., u n u '1 u .., , u .., u n , u 4.0 sources that are used seasonally or for emergency purposes, The annual average radium and gross alpha concentrations that are sampled and measured in the distribution system would be reduced by blending Wells 2 and 3 with treated water supplied from the water treatment plant. Water Distribution System Model Update The City's water distribution system model was updated with recent improvements to the water distribution system, WaterCAD (version 5,0) by Haestad Methods was the computer software used for this analysis, Hydrant flow testing was conducted throughout the City to obtain data for calibrating the model. Average day water pressures and maximum day fire flows were modeled with the existing water distribution system, This update assists in planning for new development areas and identifies inefficiencies that may exist in the system, 4.1 Average Day Water Pressures A verage day water pressures are depicted by pressure contours in Figure 2. The existing system pressures range from 55 to 77 psi for an average day demand scenario, Recommended Ten States Standards state that the minimum pressure in the distribution system should be 35 psi and the normal pressure should be approximately 60 to 80 psi, The available water pressures meet these recommended standards, 4.2 Available Fire Flows The available fire flow is defined as the rate of avaiiable flow at a residuai pressure of 20 psi for a specified duration. Maintaining a minimum residual pressure of 20 psi during a fire now is recommended to insure that all customers receive adequate pressure when such a fire flow is exerted on the system, Larger water mains and looping of the mains add significantly to the rate of availahle fire flow, The duration for an availahle fire now is impacted by supply output and water storage capacity, The time of day and season also affect how much of the output and storage is available to fight a fire, The Insurance Services Office (ISO) rates commercial, industrial, and public facilities based on the type and use of constmction. \Vhen a building has a fire suppression sprinkling system, the required tlow rate is dramatically reduced. but the residual pressure requirement is increased, Each fire suppression sprinkling system is individually designed for the building and type of use, The available fire !lows for the Andover water system were calculated using a worst-case scenario in the model with the following conditions: . System demands were set at maximum day; . All reservoirs were set at half full; and . Flows were run at 20 psi residual pressure. . The treatment plant and remote wells were set at the maximum output capacity. These conditions simulate a fire occurring on a high demand summer day, 2004 Wdter Systems Improvements City of ~ndover, Minnesota A-ANDOV0405,OO Page 8 ..., .J ., L.J ,.., i L.J ..., ,j n , L.J ., L.J n I u n J ,., I U ..., , U n LJ '1 L.J ,.., I lj r, o "l <.J ,., u ,., L.J ..., u n u The modeled fire flows were run up to a maximum of 3,500 gpm, The computer model can calculate higher flows but at some point they become unrealistic because there are not enough hydrants or fire equipment to deliver such high rates, The minimum residential fire flow avaiiable at any given point in a system should not be less than 750 gpm at a residual pressure of 20 psi, This represents the amount of water required to provide for two standard hose streams on a fire in a typical residential area for dwellings that are spaced 3 I to 100 feet apart, The needed fire flow for one and two family residential dwellings is based upon the separation distance between dwellings as summarized in the table below, Commercial buildings, industrial buildings, and larger residential units such as a four-plex or apartment building may likely require greater fire flows than residential dwellings, The needed fire flows for these types of building are variable and can be calculated with the ISO Method, This method is a function of the building square footage, combustibility class, occupancy factor, and exposure to adjacent buildings, Table 3 Residential Fire Flows Distance Between Buildings Needed Fire Flow (feet) (gpm) More than 100 500 31 - 100 750 II - 30 1,000 Less than 11 1,500 The computed fire flows for the current distribution system are represented in Figure 3, They are represented by fire flow contours in gallons per minute, 5.0 Combined Single Pressure Zone Analysis The Andover water system includes a low pressure zone and a high pressure zone as identified on Figure 1. The one million gallon water tower provides water storage and pressure for the high pressure zone. The high pressure zone receives mostly treated water from the water treatment plant. Well 3 pumps non-treated water directly into the high pressure zone during peak water demands. The 500,000 gallon \\'atcr tower provides water storage and pressure for the low pressure zone. The low pressure zone receives treated water from the high pressure zone during non-peak water demands, Well 2 provides the majority of water for the low pressure zone during peak water demands so customers located on the low pressure zone receive mostiy non- treated water during peak water demands. The City's two pressure zone system reqoires additional operation and maintenance compared to a single pressure zone system. The pressure redocing station and controls must be carefully monitored by City Staff and requires periodic adjustments and repairs, 2004 Wolter Systems Improvements City of P ndover, Minnesota A,ANDOV0405,OO Page 9 M J M u ,., I t..J ,.., "j M I t..J M .J ..., LJ " u " J ., I L.J ,.., J '1 L.J ,.., I LJ '1 L.J ""'T U " L.J '1 L.J '1 L.J " u 5.1 5,2 Creating a single pressure zone would require demolition of the 500,000 gallon water tower and pressure reducing station, The 500,000 gallon water tower could no longer be used because the high water elevation in the tower is approximately 45 feet less than the high water elevation in the one million gallon water tower that serves the high pressure zone, The high water elevations should match for all water towers located in a single pressure zone system, Average Day Water Pressures - Maximum Day Fire Flows A single pressure zone was modeled without the 500,000 gallon water tower and pressure reducing station to determine the expected average day water pressures and maximum day fire flows. The average day pressures are depicted in Figure 4, The existing system pressures range from 60 to 77 psi for an average day demand scenario, A combined single pressure zone would increase water pressures in the low pressure zone by approximately 19 psi with the increased hydraulic grade line, The maximum day fire nows with a single pressure zone are depicted in Figure 5, The low pressure zone would receive adequate fire nows for residential development. Figures 6 and 7 depict the average day water pressures and fire flows with the construction of 12-inch water main along Coon Creek Drive, This water main is recommended to provide water main looping and increased fire nows to the southwestern area of the City, The water main will also provide a trunk water main to serve the Rural Reserve Area development located along South Coon Creek Drive, Elevated Water Storage Needs Eliminating the 500,000 gallon water tower that serves the low pressure zone would require construction of a new water tower to replace this storage capacity, An extended period simulation (EPS) was setup in the model to check the cumulative system imbalance between the one million gallon water tower and a new, taller water tower constructed at the existing 500,000 gallon \-vater to\ver site with a matching high water elevation. Imbalances are caused when one or more elevated storage tanks within the same pressure zone do not fill and drain at the same rate, Imbalances contribute to reduced storage replenishment during high service pumping as one or more tanks will not fill to its full capacity, The location of water towers, water main sizes, and the layout of the water distribution system are important factors that affect the balance or imbalance of the system, The EPS simulation calculated a significant imbalance of approximately 18 feet between the City's two water towers while filling the towers from the water treatment plant. This means that a new water tower constructed at the existing 500,000 gallon water tower site would fill be filled 18 feet less in water elevation as the one million gallon water tower is filled to its high water elevation, This amount of imbaiance is not acceptable so a new water tower shouid not be constructed at thc existing site of the 500,000 gallon water tower. Constructing an altitude vai vc pit at the one million gallon water tower is not recommended because the tower would be filled first, isolated from the distribution system, and provide low turnover of water. 2004 WEier Systems Improvements City of A ldover, Minnesota A,ANDOV0405,OO Page 10 '1 .J n , u ., I U 'l L1 n , LJ n , L1 .., u n ..) n , L.J 1 u n J 1 u .., I .J '1 U .., L.J ,.., 1J n L.J n , o n I U The City's total elevated water storage volume is adequate for the existing water demands (see storage calculations in Appendix), However, the projected calculated storage need in Year 2020 for a projected population of 33,000 people on City water is approximately 3 million gallons which also assumes the water treatment plant will be expanded in the future, A two million gallon capacity water tower in addition to the existing one million gallon water tower should provide the City with adequate storage capacity for the maximum day water demands and fire flows through Year 2020, Constructing a larger two million gallon water tower would be more cost effective compared to constructing multiple water towers with less capacity in the near future. Constructing a new water tower near the water treatment plant would provide excellent hydraulic balance between the two water towers, Figure 8 shows the proposed site for a proposed two million gallon water tower. 2004 We ter Systems Improvements City of A ldover, Minnesota A-ANDOV040S,OO Page 11 "1 U ,., u ...., ! \,.J ,., u .-., , u ,., u ..., w ,., , J n I W ..., , u ..., J '1 u ..., LJ '1 d ..., u ,., i U ,., U ,., , , ..; ,., i L.J List of Figures Figure 1 - Existing Water System Figure 2 - Water Distribution System Analysis Existing Average Day Pressure Figure 3 - Water Distribution System Analysis Existing Maximum Day Fire Flows Figure 4 - Water Distribution System Analysis One Zone Average Day Pressure Figure 5 - Water Distribution System Analysis One Zone Maximum Day Fire Flows Figure 6 - Water Distribution System Analysis One Zone with Additional 12" Loop Average Day Pressure Figure 7 - Water Distribution System Analysis One Zone with Additional 12" Loop Maximum Day Fire Fiows Figure 8 - Proposed Improvements - - 0 0'0 0 .....
