PAUL WASECA Attached is a copy of the Feasibility Study the City Council ordered for the improve- ments to Macon Street and Riverview Drive. As you are aware, this Feasibility Study analyzes extending City sanitary sewer, watermain, permanent streets, and storm drainage to Macon Street and Riverview Drive. One side of this area consists of existing lots, while the other side consists of Outlot A and B of Country Crossing Third Addition which are anticipated to be replatted into new urban-sized lots. As indicated when the Feasibility Study was ordered, the Feasibility Study recommends that the existing lot be assessed for street and storm sewer at this time, but sanitary sewer and water assessments be held until such time as the individual properties choose to hook up to these utilities or these utilities are extended throughout the entire development. On the Country Crossing side, the Feasibility proposes that the Developer pay his fair share at this time for all improvements. Attached is a Resolution which formalizes the previous Council action by accepting the Feasibility Study and ordering a public hearing for May 5, 1997. At that time, I will be prepared to make a presentation of the material contained in the Feasibility Study and answer any questions the affected property owners or City Council may have. Please remember to bring your Feasibility Study to that public hearing. If you have any questions regarding this, please call. Sincerely, MSA, CONSULTING ENGINEERS Terry J. Maurer, P.E.

The City is requesting MnDOT t%ancing for the improvements which include fencing and/or lighting along the TH 169 corridor. He stated that MnDOT is requesting public participation as part of the project development process. Terry Maurer reviewed the following issues that have taken place to date regara~ug safety concerns along Highway 169. · MnDOT has extended the t~ruing of the yellow lights by one second. · MuDOT studied the t~m~-g of pedestrian crossing and detemined that no change was necessary. · The installation of waru~ug flashers is being studied by MnDOT. · It has been suggested that the 45 mph speed l~mit be extended further north.

Tom Warner - stated that he is in favor of lighting the 169 corridor, however, he is not totally in favor of fencing. He indicated that the main issue is to get people safely across Highway 169 and feels that the best way to accomplish this is with an overpass. He indicated that a fence would not always deter people from crossing the highway because there is always the potential of people going around or over the fence. Tom Warner indicated that the $200,000 needed for corridor fencing would be better spent by adding it to the cost of a pedestrian bridge and walkways. Mr. Warner also indicated that it is vital that the City consider acquiring land for a bridge overpass and walkways. Mike Kedrowski indicated that he is in favor of movin§ ahead with the lighting project but not sure that a fence will keep people from crossing the HighwaY. He indicated that a bridge overpass would better accomplish this.

ETING Thursday, February 20, 1997 City Hall Staff Present: Terry Maurer, City Engineer Andy Brotzler, MSA Meeting gl (5:30- 6:30 p.m.) for Business Owners along TH169 south of School Street. No business owners were present for this meeting. Meeting//2 (6:30-7:30 p.m.) for Residents living south of School Street, east of TH169. See attached sign-up sheet for attendance. Terry Maurer, City Engineer, stated that the City has been working with MnDOT to facilitate safety improvements along TH169 between Main Street and 193rd Avenue. The City is requesting MnDOT financing for the improvements which include fencing and/or lighting on the TH169 corridor. He stated that MnDOT is requesting a Public Participation Program as part of the project development process. Terry Maurer reviewed the following issues that have taken place to-date regarding safety concerns along Highway 169: MnDOT has extended the timing of the yellow lights by one second and moved some loop detectors further away from the signal I. ight intersection. MnDOT studied the timing of pedestrian crossing and determined that no change was necessary. Installation of warning flashers is being studied by MnDOT. It has been suggested that the 45 mph speed limit be extended further north. MnDOT is studying this request. City staff is studying the possibility of constructing a pedestrian bridge. An ISTEA Grant Application has been submitted requesting funding for this consumction. Fencing along the TH169 right-of-way is being considered between Main Street and 193rd Avenue. Lighting along the TH169 corridor between Main Street and 193rd Avenue is being considered. Terry went on to explain that the lights would be standard 40-foot high cobra headlights placed every 150-feet on opposite sides of the highway so, essentially,, there would be a light every 300-feet on each side of the highway. He also explained that the type of fencing being considered is a 5-foot high chain link fence that would be installed along the right-of-way. He indicated that MnDOT would request that the City provide the electricity for the lights and take on a normal maintenance, such as relamping or repainting, if necessary. MnDOT would maintain responsibility for major repairs such 230/347-241 l.feb An Equal Opportunity Employer TH169 CORRIDOR PUBLIC PARTICIPATION MEETING MINUTES (Continued) as a light being knocked down due to accident. He indicated that with the fencing being considered, there was a concern that the right-of-way would be opened up on the north end by the entrance to Elk Park Center and on the south end by the intersection of Fifth Street on the east side of the highway. He also indicated that there may be concerns about the aesthetics of the fencing since MnDOT will not be responsible, nor will the City have manpower or time available to pick up litter or trim weeds. This would likely fall to the responsibility of the adjacent property owners or a civic organization. Terry indicated that no design had been ordered yet. The purpose of the meeting was not to discuss specifics regarding the improvements, but to take public input, comments, and try to answer any general questions the public may have. With that, the meeting was opened up to the public. CO1ViMENTS Joel Rademacher, 11224 190th Avenue NW - he stated that he is more in favor of the fence. Fencing he thought was a good idea. He doesn't believe there is a safe place to cross the highway and crossings are not marked properly. Signal lights do not provide a long enough time for pedestrian crossing. He would prefer.that the City focus their attention on a safe way to cross the highway, preferably with a pedestrian bridge. Linda Twaddle, 18994 Zane Street NW - she said she was confused with MnDOT's position of not wanting to increase pedestrian crossing time by one to two seconds. She did not feel there was adequate time for pedestrian crossing at the intersections. She wondered what Mn.DOT was losing if they lengthen the pedestrian light times. StAve SChoemaker, 11106 190th Avenue NW - he asked what the cost of the pedestrian bridge would be and what was holding up funding for its construction. He thought the solution to the safety problem was to put the bridge up rather than to spend money on lights and fencing. He related these to spending money on Band-Aid solutions. He suggested that the money that would be spent on light and fencing be put into a pot with addition contributions from MnDOT, the City, and the County to get enough to fund a pedestrian bridge. Pat Korte, 19031 Main Street NW - he stated that a pedestrian bridge would not force use. He thought the fencing was a good first step. He sees both adults and children crossing TH169 between the intersections. He suggested that the fence and lights be installed as soon as possible, and a pedestrian bridge be in the immediate future. Tom Cruz, 11146 190th Avenue NW - he questioned why the intersection of School Street and Elk Hills Drive at TH169 was not square. He thought that squaring up the intersection would reduce pedestrian's exposure to vehicle traffic when crossing. It seems 230/347-241 l.feb 2 TH169 CORRIDOR PUBLIC PARTICIPATION MEETING MINUTES (Continued) to take longer to cross because it is not square. Terry answered that it is not square because of the much higher traffic volume on the west side on School Street due to Elk Park Center. Two left tums onto School Street from TH169 causes the geometrics to be different on all four lengths of the intersection. He indicated that this could not be changed. Mr. Cruz went on to indicate that the amount of traffic now, and future traffic, is a major concern. The best thing to do would be to put an overpass over TH169. He felt that the amount of traffic makes it tough for pedestrian crossing at the intersection. He also indicated that his daughter is a school crossing guard and he is concerned with her crossing the highway. If he is not available to pick her up after school, he does not allow her to perform her duties as a school guard. Suggests a pedestrian bridge be built ?~.soon as possible. Jeanie Williams, 19041 Zane Street NW - she agreed with Tom Cruz's comments. She is not happy with MnDOT's comments regarding the crossing. She wants a safe place to cross without getting stuck on the island at the intersections. Sue Schoemaker, 11106 190th Avenue NW - she commented that MnDOT's test of the time to cross the signal last fall was not realistic. Having people out there with orange vests on and MnDOT trucks around did not model the real event. Regardless of what the MnDOT experiment showed, she does not feel that the crossing is safe. She stated that MnDOT is concerned about moving traffic and not necessarily concerned about the lives of the residents of Elk River. Joel Rademacher, 11224 190th Avenue NW - he stated that being a second driver in the line at School Street, the light is green and then is yellow by the time he gets to the intersection. The timing is off and it should be checked. Tom Cruz, 11146 190th Avenue NW - he is concerned about the article that appeared in [ the paper that stated that one in four cars are running red lights. Terry commented that , MnDOT has indicated that at any given time, 20 percent, of the timing on their traffic "." signals CoUld be in error. When the public sees a s'ituation, as indicated' by Joel Rademacher, they should call either City Hall or MnDOT and MnDOT will check it out. Mike Twaddle, 18994 Zane Street NW - he stated that the number of existing residential units on the east side of the highway and the potential for a significant increase number in them in the near future, along with all the business interests, schools and pedestrian pathways on the west side makes safety for pedestrians crossing .the highway a top priority. He stated that he did not know how to correctly cross at the at grade crossing until MnDOT explained it. He wondered how we could expect the children to know how to cross it. He realizes that we will need to educate through parents, school, and police force. He stated that we have to fence the right-of-way even though he would like to see a pedestrian bridge. He felt that without the fence, there would be no way to funnel the 230/347-2411 .feb 3 TH 169 CORRIDOR PUBLIC PARTICIPATION MEETING MINUTES (Continued) people to the pedestrian crossing and that the public would have a tendency to take the easiest way. He is in favor of lights along the corridor. He says that the corridor is very dark, especially in the winter. With the headlights of cars often dirty, it is very difficult to see. He stated that MnDOT constantly gives cookbook answers to each of these unique situations and they need to be looked at with unique solutions to the problems in Elk River. The City needs to help do something soon. They have waited too long already and the money needs to be found. Linda Twaddle, 18994 Zane Street NW - she indicated she would not allow her 'kids to walk across the highway. She said that we all have a tendency to jaywalk but need to be encouraged to use the crosswalk. She stated that she has stopped often times along the highway near the water tower and has never seen a police car come by ~vhile she has been stopped there. We need more enforcement along the corridor of pedestrian rules, along with vehicle laws. Need to do something to address the issues related to the two deaths in the last year and all of the "almost" accidents. She felt tha.t it had to be a collaborative effort between State, City,. County, and citizens. Jerry Hagen, Saxs Foods - He explained the involvement of the Chamber of Commerce. He felt that there was actually a bUsinesS issue for the safety of the bUsiness customers. We need: to have MnDOT know .that businesses are'getting into the lobbying and contacting state-level representatiVes. He asked those in attendance to talk to other businesses in the community and make them aware of the Chamber's efforts and have them contact Jerry if they were unaware of what the Chamber was trying to do. Steve Schoemaker, 11106 190th AVenUe NW - he asked abOut the Park dedication fees. He stated that all the properties on the east side of the highway had paid park dedication fees and he wondered if those monies could be used to help fund some of the · improvements since it appears that they have not funded a park improvement on that side. He asked how much money was in the fund and what it was used for. Ted Schoetzko, 19054 Zane Street NW - he indicated that if you don't hit the pedestrian cross button, there is not enough time to get across. Why doesn't MnDOT change the phasing of the lights. He went on to state that the left turn from southbound TH169 at 193rd tums ween without any cars at the intersection. Steve Rusher, 11189 190th Avenue NW - he asked whether retiming of the lights is a MnDOT issue. It was stated that MnDOT does control the timing of. the lights. He also stated that after the accident last fall, he saw kids crossing in the middle of the highway corridor and not at the intersections. A police officer was traveling on the highway at that time and did nothing. He indicated that he felt there needs to be more law enforcement of the pedestrian laws along the corridor. 230/347-2411.feb 4 TH169 CORRIDOR PUBLIC PARTICIPATION MEETING MINUTES (Continued) Tom Cruz, 11146 190th Avenue NW - he asked a question of whether we need more overhead crossings if more homes are to be built. He indicated that he thought a second elevated pedestrian crossing should be built by 193rd Avenue. Lester Morris, 19337 Denver Street NW - he indicated that he worked for the Mille Lacs Indian Nation and that he has been working with MnDOT for a project improvement on TH169 near the Mille Lacs Band facilities. He indicated that they have been having trouble but have found a way through them and he was going to provide to Jerry Hagen's committee a summary of how they were able to get their project accomplished. He stated that he now lives in Elk River and was concerned when he saw that the City Council ,meeting. that MnDOT appeared at on cable t.v. because the answers given by MnDOT at that meeting were identical to the answers he received when discussing the improvements that were requested near the Mille Lacs Casino. He indicated that he wanted to help the community any way he could from his experience in daaling with MnDOT. Daryl Thompson, City Council Member - he indicated his position on the lighting and fencing. He was in favor of most of the comments he had heard tonight. He went on to comment about meetings with the State representatives. It was his understanding that one of these representatives was considering authorizing a bill in the State Legislation to try and get funding for the pedestrian bridge. He also indicated that in an earlier meeting with MnDOT, they: indicated that they would extend the red-r~d timing at the intersections. He had wondered if that had been taken care of.. Connie Levang, 19047 Nowthen Boulevard - she indicated that she drives northbound on TH 169 quite often and that she is very comfortable with the timing of the lights. She does not perceive that there is undue delay for the traffic on the highway due to timing for cross streets and/or pedestrian. She would not have a problem as a motoring person to have the time extended slightly and wondered what MnDOT's objection to doing that was. She also commented that the corridor is very dark and she thought lighting would be a good idea. There being no further comments, the Public Participation Meeting ended at 7:55 p.m. SDG:kh 230/347-2411 .feb 5 CONSULTING B'GINEE~ 1326 Energy Park Drive St. Paul, MN 55108 612-64~'4389 1-800-888-2923 Fax' 612-6~4-9~6 February 5, 1997 File: 230-347-90 Dear TH 169 Business Owner: As you may be aware, the City Council of Elk River has been working closely with MnDOT to facilitate safety improvements along the TH 169 corridor between Main Street and 193rd Avenue.

INTRODUCTION On April 7, 1997, the Elk River City Council adopted Resolution 97-25 authorizing the preparation of this feasibility for Macon Street and Riverview Drive. The resolution was based on a petition received from Country Ridge Development. The petition is valid since the petitioner owns over 35 percent of the affected property. The area being studied is shown in Exhibit 1. This report will analyze the extension of City sanitary sewer and water to serve the existing lots and proposed lots along Macon Street and Riverview Drive. Also, it will consider construction of new permanent streets, including concrete curb and gutter and appropriate storm sewer. II. PROJECT HISTORY In June 1996, the preliminary plat of Country Crossing 3rd Addition was approved. That preliminary plat showed the potential for lots along Macon Street and Riverview Drive. When the final plat was approved in August of 1996, the lots along Macon Street and Riverview Drive were replaced with Outlot A and Outlot B. In approximately the same time frame, the City of Elk River initiated a Feasibility Study to look at extending City utilities and reconstructing permanent streets throughout the Riverview Heights and Grandview additions. That Feasibility Study was brought forward and a public hearing was held. At the public hearing, the decision was made not to proceed with the improvement. Immediately, the City Council initiated an overlay project for the same area, excluding Macon Street and Riverview Drive. These two streets were excluded because of the potential for the platting of the additional lots approved with Country Crossing 3rd Addition. The Developer of Country Crossing 3rd Addition has now petitioned for the improvements necessary to serve these additional lots. III. PROJECT SCOPE The purpose of this study is to analyze the feasibility of providing sanitary sewer and watermain to the existing and proposed lots along Macon Street and Riverview Drive, while reconstructing the streets to the City standard of 32 feet wide with barrier style concrete curb and gutter. Storm sewer will be added where needed. This study will discuss the existing conditions, proposed improvements, and estimated construction costs FEAS-230.365 - 1- 230-365- !0 LAKE ORONO LAKE c~OS~ PROd~T LOCATION ER365-LO MILE LOCATION MAP MACON ST. AND RIVERVlEW DR. glk iver plus associated overhead costs. Overhead costs include City administration, engineering, fiscal and legal expenses. The City's Assessment Manual and previous projects will be used as a guide to discuss financing methods for this project. IV. NEED, COST-EFFECTIVENESS, AND FEASIBILITY The oldest of the subdivisions discussed in this report are in the 20-year range. The streets in the Riverview Heights and Grandview area are in disrepair and need some attention. The wells and septic systems of the oldest homes are nearing the end of their useful life. The entire area considered in this report is contained within the City's urban service District. There is clearly a need for street construction, as well as a need for City sewer and water. The most cost-effective way to approach this would be to look at extending City utilities prior to constructing a permanent street. Based on the information contained within this report, the proposed improvements are feasible from an engineering standpoint. V. EXISTING CONDITIONS Grandview 1st and 2nd Additions contain three rural, residential streets: Macon Street and a continued segment of Riverview Drive from approximately 350 feet east of Naples to Joplin Avenue and 178th Avenue. Of these three, two residential streets Macon Street and Riverview Drive, are proposed for improvements. All streets in the area are bituminous and approximately 24 to 25 feet wide. Currently, there is no curb and gutter or storm sewer system. Presently, storm water runoff runs overland and eventually drains toward the Mississippi River or Orono Lake. There are approximately 17 existing lots and 24 proposed lots, with the subdivision of Outlots A and B, Country Crossing 3rdAddition, located within the proposed project area. The entire area is zoned R1C - Single Family Residential. The rights-of-way are 66 feet wide. Currently, all existing houses in the area have on-site sanitary sewer systems and private wells. The existing developments, excluding Country Crossing 3rd Addition, included in this project are approximately 20 years old. The streets are generally in need of upgrading. The on-site sewer systems and wells are generally of the same age. FEAS-230.365 -3- 230-365-10 VI. PROPOSED IMPROVEMENTS Each of the proposed improvements is detailed as follows: A. Sanitary Sewer The proposed sanitary sewer improvements, as shown on Exhibit 2, consist of extending an 8-inch sanitary sewer to Grandview 2nd Addition, Outlots A and B of Country Crossing 3rd Addition, and Grandview Addition, Block 1. This proposed alignment will allow for future extensions of sanitary sewer links to Grandview Addition, Blocks 1 and 3, and a section of Palmers Addition. The proposed sanitary sewer will extend from the existing main at County Road No. 30 and Country Crossing 3rd Addition to Macon Street. The sanitary sewer will extend south to Riverview Drive and then east to the intersection of Joplin Street and Riverview Drive. Each existing and proposed lot will have a 4-inch sewer service constructed to the property line. In the future, gravity sewer extensions would extend west from the intersection of Macon Street and Riverview Drive to access the next four lots. Also, an extension south on Joplin Street to Riverview Drive and east to serve the first few lots in Palmers Addition. In future extensions, it is not feasible to serve the properties abutting 178th Avenue by gravity sanitary sewer. Therefore, a small lift station and associated forcemain would be constructed near the bottom of the hill on 178th Avenue. The effluent would be pumped to the manhole at the intersection of 178th Avenue and Riverview Drive, where the forcemain would enter the gravity system. B. Watermain The proposed water improvements, shown on Exhibit 3, consist of a 6-inch watermain starting at the west lot line of Lot 1 in Grandview 2nd Addition and County Road No. 30. The proposed 6-inch watermain will extend east to the intersection of Macon Street and County Road No. 30 then south on Macon Street to Riverview Drive and east to Joplin Street. From Joplin Street it will connect to FEAS-230.365 -4- 230-365-10 )AD NO. 30 - i o ~ 79~TH ~ENJ~, LANDIN ' / / .

Each existing and proposed lot will have a 1-inch water service constructed to property line. Looping of the trunk waterman system is necessary to maintain adequate pressure in the system to meet anticipated flow demands. "Looping" will also provide for circulation of water in the system and eliminate dead-end lines that result in stagnant water. Providing a "looped" system will allow for the extension of lateral systems to the surrounding area, as well as helping to minimize the number of users without service during times of maintenance and repair to the system. C. Street Construction The proposed street section, shown in Exhibit 4, consists of a 32-foot wide street with barrier concrete curb and gutter. The proposed street section provides 6-inches of Class 5 aggregate base, 2-inches of bituminous base course, and 1-inch of bituminous wear course. This street section is typical for residential areas in Elk River based on the native soil types present. Each existing driveway will be provided with a concrete apron and all disturbed existing yards will be sodded and Outlots A and B of Country Crossing 3rd Addition will be seeded. Proposed street construction will consist of Macon Street and Riverview Drive, as shown in Exhibit 5. D. Storm Sewer The proposed storm sewer improvements, shown on Exhibit 5, consist of extending catchbasins and small diameter storm sewer from County Road No. 30 south on Macon Street. This will collect the majority of the Macon Street water runoff. This water will be routed to the County Road No. 30 southern ditch. The water will then flow in the ditch to the Country Crossing 3rd Addition storm sewer system south of County Road No. 30.

IMPLEMENTATION CONSIDERATIONS Ao Easements and Right of Way The existing rights-of-way within the project area are 66 feet wide. These existing rights-of-way should be adequate for the work proposed. Grading of existing driveways and/or boulevard areas may require permission from the property owners. B. Permits Several permits will be required prior to construction of the proposed improvements. The permits that will be required are listed below: Minnesota Pollution Control Agency permit for the construction of the proposed sanitary sewer improvements. Minnesota Department of Health permit for the construction of the proposed watermain improvements. Minnesota Pollution Control Agency permit for grading may be required for construction. Sherburne County permit for the construction of the proposed watermain within County Road No. 30 right-of-way. C. Estimated Costs The estimated construction costs and associated overhead costs for the proposed improvements are shown in Table 1. In accordance with the City's Assessment Manual, the overhead costs have been estimated as 28 % of the total project cost. FEAS-230.365 - 1 0- 230-365-10 Dw The overhead cost includes City administration, engineering design, construction staking and inspection, assessment, and fiscal and legal costs. Table 1 Estimated Project Costs 1. Sanitary Sewer $136,000 2. Water $87,000 3. Storm Sewer $15,000 4. Street $145,000 Estimated Total Construction Cost $383,000 Overhead (28%) $107,300 Estimated Total Project Cost $490,300 Financing It is proposed to assess the cost of the improvements to the abutting properties. The sanitary sewer and water improvements are proposed to be assessed on a per lot basis, while the street and storm sewer costs are proposed to be equally split between the existing lots and the future lots of Country Crossing 3rd Addition. On the west side of Macon Street and the south side of Riverview Drive, there are 17 existing lots that could reasonably be served by these improvements. When the preliminary plat for Country Crossing 3rd Addition was approved, it showed the further subdivision of Outlots A and B to create 24 lots on the east side of Macon Street and the north side of Riverview Drive. Therefore, for purposes of assessment on the sanitary sewer and water costs, there are a grand total of 41 lots. These lots are shown on Exhibit 6. Based on the estimated total project cost for the sanitary sewer and 41 assessable lots, the cost per lot would be $4,250. Likewise, based on the total estimated project cost for the water improvements and 41 assessable lots, the assessment per lot would be $2,725. The storm sewer and street costs divided in half between the existing lots and Country Crossing 3rd Addition would result in a cost of $102,700 per side. Dividing that by the existing or proposed lots would indicate that the existing lots on the west side of Macon Street and south side of Riverview Drive FEAS-230.365 - 1 1 - 230-365- I 0 ~OUNT¥ /ROAD 1 ER365-E1 o 5oo T PROPERTIES TO BE ASSESSED PROPERTIES ASSESSED PREVIOUSLY FOR OVERLAY ASSESSMENTS ~ MACON ST.

The following table gives a surranary of the total assessment proposed for the existing lots and the proposed lots of Country Crossing 3rd Addition. Proposed Country Existing Lots Crossing Lots Sanitary Sewer $4,250 $4,250 Water $2,725 $2,725 !Street/Storm Sewer $6,000 $4,300 TOTAL $12,975 $11,275 As discussed earlier, the City Council has indicated they would hold the sanitary sewer and water assessments against the existing lots until such time that those property owners choose to hook up to the sanitary sewer and/or water, or until the utilities are extended through the entire subdivision. Therefore, the assessment that would be levied with these improvements against those properties would be the $6,000 street and storm drainage cost. Them are two lots near the intersection of Macon Street and Riverview Drive, Lot 7 Block 2 and Lot 1 Block 3, Grandview Addition, which have been previously assessed for the overlay project. These two lots could be reasonably served by the sanitary sewer and water, and do at least partially abut the street improvements. Therefore, if the City Council desires, these two lots could be included in this improvement, in which case it would be appropriate to give a credit for the previously assessed overlay improvement. As an alternative, these two lots could be excluded from this improvement because of the previous overlay assessment. In either case, the sanitary sewer and water would be available to these two lots should they choose to hook up at some time in the future. FEAS-230.365 - 13- 230-365-10 VIII. F.
