BACKGROUND On September 27, 2004, Council authorized the preparation of the 2005 Street Improvement Feasibility Report. On November 17,2004, staff held an open house meeting with residents on Lake Lucy Road regarding sewer and water improvements. On December 1, 2004, staff held an open house for all property owners in the 2005 Street Improvement project area to discuss the improvements and receive comments. On December 13,2004, Council called a public hearing for the 2005 Street Improvement Project for January 10, 2005. DISCUSSION While the attached feasibility study describes the proposed project in detail, staff wanted to give a blief summary of each of the proposed improvement areas. Lake Lucy Road Area · Project area includes Lake Lucy Road from Galpin Boulevard to Powers Boulevard, Steller Court, and Chming Bend. · Proposed improvements include: nanowing Lake Lucy Road from 36- feet wide down to 32-feet; edge milling and overlaying all of the streets; installing concrete curb and gutter on Lake Lucy Road and Steller Court; adding an off- street trail along Lake Lucy Road; adding a southbound turn lane at the The City of Chanhassen · A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play. Paul Oehme January 5,2005 Page 2 intersection of Lake Lucy Road/Powers Boulevard; and extending sanitary sewer and water to serve parcels along Lake Lucy Road and Steller Court. · Street assessments are proposed for those properties that access onto the roads within the project area. The assessments are for 40% of the improvements for a residential roadway and new curb and gutter. The assessments do not include the road nanowing, trail improvements, or oversizing of the roadway from a residential to a collector. The assessments were calculated on a per lot basis. The preliminary assessment amount for Lake Lucy Road and Steller Court is $2,892/10t. The assessment amount for Charing Bend of $1,627 is slightly less since the street already has curb and gutter. The street assessments are proposed to be assessed over an 8-year peliod at 6% interest. · To get a better understanding of whether the residents along Lake Lucy Road were interested in utility extensions or subdividing their property, the City surveyed the neighborhood on these issues. Ballots were sent to the existing residents and the results are shown below, No. of residents balloted 20 No. of residents who responded 19 No. of residents who wanUdon't want sewer 919 No. of residents who wanUdon't want water 4/10 No. of residents who wanUdon't want to subdivide 8/12 Based on the fact that now is the best time to extend the utilities since the roads will be under construction, it is recommended that the sanitary sewer be extended at this time. With the extension of the sanitm'y sewer, the City will be better prepared for the inevitable time when the existing septic system fails. Also, based on the ballot response, staff is not recommending these properties be rezoned for subdividing at this time. · Utility improvements are proposed to be assessed to the benefiting properties at 100% of the cost of the improvements in accordance with the City's assessment practice. The assessments were calculated on a per lot basis. The proposed sanitary sewer assessment is $28,112/10t for Lake Lucy Road and Steller Court. The proposed water assessment for Lake Lucy Road is $3,780/1ot and for Steller Court is $8,694/10t. The utility assessments are proposed to be assessed over a IS-year peliod at approximately 6% interest. For the properties that do not want the sanitary sewer extended at this time, their assessments are proposed to be defened for a peliod of up to 10 years at an interest rate of 6% or until they connect to the sewer. A consultation report is cunently being drafted to evaluate the cosUbenefit for these improvements. Once the consultation report is finalized the assessment methodology may be Paul Oehme January 5,2005 Page 3 adjusted to reflect the true benefit. Pioneer Trail Area · Project area includes Foxford Road, Eastwood Court, Meadowlark Lane, Deebrook Dlive, Homestead Lane, Flintlock Trail, and Pineview Court. · Proposed improvements generally include an edge mill, crack repair, and a 1.5" overlay of the full street width. It should be noted that the feasibility study recommends bidding out both an edge mill and overlay along with an alternate for a full-depth mill and overlay to determine which cost is more competitive. · Street assessments for the area are proposed in accordance with past practice and the City's assessment practice at a rate of 40% of the project cost to the benefiting lots that abut the streets within the project area. The assessments were calculated on a per lot basis, The proposed assessments for the lots in this area range from approximately $1,838 to $2,433. The street assessments are proposed to be assessed over an 8-year peliod at 6% interest. Chan View Area · Project area includes: Market Boulevard north of W, 78th Street and Chan View between Market Boulevard and Laredo Drive. · Proposed improvements include an edge mill, crack repair and overlay of the full street width and storm sewer improvements. · Assessments are proposed for all properties that access the roadways. This includes three City properties: Library site, City Hall, and the Fire Station. Only two private properties are proposed to be assessed: the Post Office site and the Chanhassen Bank property. Assessments for this area were calculated on a front-foot basis, The proposed assessment for the Post Office is $8,719 and $4,228 for the Chanhassen Bank. The street assessments are proposed to be assessed over an 8-year period at 6% interest. City Hall & Fire Station · Proposed improvements include milling and overlaying the two eastern parking lots of City Hall and the Fire Station #1 parking lot. The fire station is also proposed to receive an 8" thick concrete driveway for the heavy trucks that use the station's garage. Paul Oehme January 5,2005 Page 4 · No assessments are proposed for this portion of the project since they are City-owned. Miscellaneous Work Included in this year's project is miscellaneous curb and gutter repair at various locations throughout the city and tlial repairs, By including these items in a large street improvement project, it is anticipated the City will receive better bids verses obtaining quotes from contractors for this work. The estimated cost for this work is $65,000. Funding Summary Funding for this project is proposed as follows: ITEM EST. 2005 CIP COST BUDGET 2005 CIP Proj. # AMOUNT Bonding Amount Sanitary Sewer Assessments $506,011 Water Main Assessments $46,115 Street Assessments $402,788 Ad Velorem Debt $395,930 Subtotal $1,350,844 $1,500,000 ST-012 MSA $644,535 $800,000 ST -012 Storm Sewer Utility Fund $50,365 $100,000 SWMP-019 Capital Replacement Fund $130,725 $182,000 MB-008 Pavement Management Fund $65.000 $65.000 ST -018 TOTAL $2,241,469 $2,647,000 Schedule The tentative schedule for this project is as follows: Approve Plans & Specifications, Authorize Bids Open Bids Assessment Healing & Award Contract Begin Construction Substantial Completion March 2005 Aplil 2005 May 2005 May 2005 September 2005 Paul Oehme January 5,2005 Page 5 RECOMMENDATION Staff is recommending that the City Council approve the attached resolution and authorize the preparation of plans and specifications for the 2005 Street Improvement Project.

This roadway was last reviewed for improvement in 2001. Since then the pavement condition for this collector road has severely deteriorated with transverse cracks and rutting appearing on the pavementsurface. The existing road also has cross slope irregularities in the crown section. A sanitary sewer trunk line runs through the eastern half of the corridor. A water maintrunk runs the entire length of the corridor, but services have not been extended to all properties along Lake Lucy Road. Proposed street improvements include narrowing of the roadway to 32 feet including the addition of concrete curb and gutter. The narrowing of the road is anticipated to cause a traffic calming effect. The narrowing of the road will not reduce the capacity of the road to safely carry traffic now or in the future. The current traffic volume is 3,250 ADT (Average Daily Traffic) and the projected 2020 traffic volume is 5,200 ADT.Based on this data the road can be narrowed and safely carry the expected traffic. Safety improvements will also include the addition of a right turn lane at Powers Boulevard and Lake Lucy Road. A 10-foot wide off-street bituminous trail will also be added to the corridor. This will alleviate safety concerns with traffic and bicycle conflicts. The bituminous trail is proposed to be constructed on the north side of the roadway.The trail is recommended to be located on the north side of Lake Lucy Road because of wetland, steep driveways, lack of right of way and steep grades on the south side of Lake Lucy Road. Pavement rehabilitation will include a 1-1/2-inchdeep edge mill of the existing pavement and a full depth mill and patch in areas where severe transverse cracking exists. The overlay of the roadway will be performed to reestablish a crown section on the road. These improvements will increase the overall pavement strength of the road. The roadway will be narrowed on the north side only, thus requiring that new catch basins be added at all low points and at all crossings on one side only. New casting assemblies will be installed at all existing and proposed catch basin locations. Refer to Figure 2, Sheet 1 for the proposed street improvements on Lake Lucy Road. A sanitary sewer trunk line will be extended fromjust west of Yosemite to Galpin Boulevard. The trunk line will run along the south side of the road in the boulevard area and connect to a lift station at the intersection of Lucy Ridge Lane.Service lines will be provided to properties on the north side of Lake Lucy Road that are to be served with sanitary sewer. The service lines will be directionally drilled to the properties to be served which are located on the north side of the road. By directionally drilling the pavement, restoration costs will be minimized. There is one City of Chanhassen,MNHTPO, Inc. 6 Ð®»´·³·²¿®§ Ú»¿·¾·´·¬§ Î»°±®¬Ø¿²»² Ì¸±®° Ð»´´·²»² Ñ´±²ô ×²½ îððë Í¬®»»¬ ×³°®±ª»³»²¬ Ð®±¶»½¬Ò±ò ðëóðï property (Parcel No. 10 on Figure 4, Sheet 2) within the sewer extension area on the north side of Lake Lucy Road that is not proposed to get sewer service with this project. This parcel recently installed a new septic system. Initially, a credit for the septic system was considered to be applied toward a proposed sanitary sewer assessment but this credit would be approximately the same amount as it would cost to directionally drill the sanitary service to the parcel from the south side of Lake Lucy Road. When the septic system for Parcel 10 fails in the future, the parcel will be required to connect to the sanitary sewer at their own expense. In addition to the improvements on Lake Lucy Road, the trunk sanitary sewer system will be extended up Steller Court to serve the 5 lots located in the cul-de-sac. The service leads will be 6-inches in diameter to all properties that are less than 30,000 square feet, which are too small to subdivide. The service lead will be 8-inches in diameter to all properties 30,000 square feet and greater. These properties are potentially large enough to subdivide in the future. Refer to Figure 2, Sheet 2 for the proposed sanitary sewer improvements on Lake Lucy Road. Option #1 for the proposed sanitary sewer improvements will involveopen cut installation of the trunk sewer line. Option #2 for the sanitary sewer improvements involves directional drilling of the trunk sewer line through the wetland area. Advantages of Option #1 is that the cost is cheaper and the open cut installation allows for soils correction and proper bedding of the pipe, thus reducing settlement concerns. The advantage of Option #2 is that the main will be directionally drilled through the wetland area, reducing impacts from open cutting. Option #1 is the preferred option and we recommend the approval of choosing Option #1. Proposed improvements to the water main system include stubbing service lines to properties adjacent to Lake Lucy Road that have requestedthe services and extending service to properties along Steller Court. The trunk water main runs along the north side of the road in the boulevard area. The service lines will be directionally drilled to the properties to be served which are located on the south side of the road. The service leads will be 1-inch in diameter to all properties that are less than 30,000 square feet, which are too small to subdivide. The service lead will be 6-inches in diameter to all properties 30,000 square feet or greater. These properties are large enough to potentially subdivide in the future. Refer to Figure 2, Sheet 2 for the proposed water main improvements on Lake Lucy Road. To get a better understanding of whether the residents along Lake Lucy Road were interested in utility extensions or subdividing their property the City surveyed the neighborhood on these issues. Ballots were sent to the existing residents and the results are shown below. No. of residents balloted 20 No. of residents who responded 19 No. of residents who want/don't want sewer 9/9 No. of residents who want/don't want water 4/10 No. of residents who want/don't want to subdivide 8/12 City of Chanhassen,MNHTPO, Inc. 7 Ð®»´·³·²¿®§ Ú»¿·¾·´·¬§ Î»°±®¬Ø¿²»² Ì¸±®° Ð»´´·²»² Ñ´±²ô ×²½ îððë Í¬®»»¬ ×³°®±ª»³»²¬ Ð®±¶»½¬Ò±ò ðëóðï Based on the fact that now is the best time to extend the utilities since the roads will be under construction, it is recommended that the sanitary sewer be extended at this time. With the extension of the sanitary sewer, the City will be better prepared for the inevitable time when the existing septic system fails. The ballot summaryincludes Steller Court properties. Steller Court is proposed to be served with both water and sewer. Based on the ballot response, staff is not recommending these properties be rezoned for subdividing at this time. The costs associated with the street improvements will be assessed per the City’s Standard Assessment Practice as found in Appendix C. However, the cost for the street narrowing, street pavement section oversizing for a collector road, storm sewer improvements and the bituminous trail will be funded by City resources as detailed in the Introduction/Summary section of this document. For Lake Lucy Road and Steller Court, assessments will be made to only the properties that have direct access to either Steller Court or Lake Lucy Road. For Charing Bend, curb and gutter all ready exists so assessments have been adjusted appropriately. All other street improvement assessment costs for Charing Bend will be the same as for Lake Lucy Road and Steller Court. These street assessments are proposed to be assessed over an 8-year period at approximately 6% interest. The costs associated with the utility improvements are proposed to be assessed 100 percent to the properties benefiting from the improvements. The utility assessments are proposed to be assessed over a 15-year period at approximately 6% interest. For the properties that do not want the sanitary sewer extended at this time, their assessments are proposed to be deferred for a period of up to 10 years at an approximate interest rate of 6% or until they connect to the sewer. The assessmentmethod used is per lot and is consistent with past practices for other residential street assessments. A consultation report is currently being drafted to evaluate the cost/benefit for these improvements. Once the consultation report is finalized the assessment methodology may be adjusted to reflect the true benefit. Even though Lake Lucy Road is an MSA/Collector route, the assessment rates are based on costs consistent with other City of Chanhassen residential streets. The City will be paying for the oversizing of the collector road pavement section. These costs are presented in the Preliminary Cost Estimate found in Appendix A. Refer to Figure 2, Sheets 1 and 2 for the proposed improvements to Lake Lucy Road and Steller Court. Steller Court Stellar Court currently has deteriorated bituminouscurb and the surface is in need of an overlay to protect and preserve the pavement structure. There are some transverse cracks, however, the current surface will require very little repair work prior to overlay.

The casting assemblies for the storm sewer system located at the intersection with Lake Lucy Road will be adjusted to finished grade. The Lake Lucy Road trunk sanitary sewer system will be extended up Steller Court to serve the 5 lots located in the cul-de-sac. The service leads will be 6-inches in diameter to all properties that are less than 30,000 square feet, which are too small to subdivide. The service lead will be 8-inches in diameter to all properties greater than 30,000 square feet. These properties are large enough to potentially subdivide in the future. Proposed improvements to the water main system include extending the trunk line located at the intersection of Lake Lucy Road and Steller Court into the cul-de-sac. Service lines will be stubbed to the lots located on Steller Court that are not currently served by the existing trunk system. The service leads will be 1-inch in diameter to all properties that are less than 30,000 square feet, which are too small to subdivide. Theservice lead will be 6-inches in diameter to all properties greater than 30,000 square feet. These properties are large enough to potentially subdivide in the future. Refer to Figure 2, Sheet 2 for the proposed water main improvements on Steller Court. The costs for Steller Court are presented in the Preliminary Cost Estimate found in Appendix A. The costs associated with the utility improvements will be assessed 100 percent to the properties benefiting from the improvements. Refer to Figure 2, Sheets 1 and 2 for the proposed improvements to Steller Court. Note that the street costs for Lake Lucy Road and Steller Court have been combined for assessment purposes due to the close proximityof their location. The costs are separated for reference as shown Appendix A. The costs associated with the street improvements will be assessed per the City’s Standard Assessment Practice as found in Appendix C. Homestead Lane Area The Homestead Lane area is defined as the properties located on Homestead Lane and Flintlock Trail. These roads have been identified as requiring pavement rehabilitation through the Pavement Management System. The pavement has severely deteriorated primarily due to the fact that there is no apparent crown on the roadway. The water sits on the road and penetrates the surface creating the transverse cracking and rutting in the pavement. Option #1: Pavement rehabilitation will include a 1–1/2-inch deep edge mill of the existing pavement and a full depth mill and patch in areaswhere severe transverse cracking exists. A City of Chanhassen,MNHTPO, Inc. 9 Ð®»´·³·²¿®§ Ú»¿·¾·´·¬§ Î»°±®¬Ø¿²»² Ì¸±®° Ð»´´·²»² Ñ´±²ô ×²½ îððë Í¬®»»¬ ×³°®±ª»³»²¬ Ð®±¶»½¬Ò±ò ðëóðï 2-inch deep overlay of the entire roadway will be performed to re-establish a crown section on the road. This will allow the water to flow off the road and into the existing ditch system. Option #2: Pavement rehabilitation will includea full depth mill of the existing pavement. The milled bituminous will be reclaimed to shape thesubgrade to allow the overlay to be performed to reestablish a crown section on the road. This will allow the water to flow off the road and into the existing ditch system. The desired pavement life of these roads is approximately 15-20 years. The advantage of Option #1 over Option #2 is that the initial cost for this option is $3,913 cheaperthan the second option which translates to a $78.30 savings in assessments per lot while also meeting the desired 15-20 year life cycle. Full reconstruction with curb and gutter is not proposed at this time because utility extensions are currently planned for the year 2020. This work will not be performed until utilities are extended. Option #1 is the preferred option and is thus presented in the Preliminary Cost Estimate found in Appendix A. Since the cost for Option #2 is very close to the cost for Option #1, it is recommended to bid Option #2 as an alternate to Option #1. Refer to Figure 2, Sheet 3 for the proposed street improvements to the Homestead Lane Area. The costs associated with the street improvements will be assessed per the City’s Standard Assessment Practice as found in Appendix C. Foxford Road Area The Foxford Road area is defined as the properties located on Foxford Road, Eastwood Court and Pine View Court. These roads have been identified as requiring maintenance through the Pavement Management System. The pavement has severely deteriorated primarily due to the fact that there is no crown evident on the roadway. The water sits on the road and penetrates the surface creating the transverse cracking and rutting in the pavement. Option #1: Pavement rehabilitation will include a 1–1/2-inch deep edge mill of the existing pavement and a full depth mill and patch in areaswhere severe transverse cracking exists. A 2-inch deep overlay of the entire roadway will be performed to re-establish a crown section on the road. This will allow the water to flow off the road and into the existing ditch system. Option #2: Pavement rehabilitation will include a full depth mill of the existing pavement. The milled bituminous will be reclaimed to shape the subgrade to allow the overlay to be performed to reestablish a crown section on the road. This will allow the water to flow off the road and into the existing ditch system. City of Chanhassen,MNHTPO, Inc. 10 Ð®»´·³·²¿®§ Ú»¿·¾·´·¬§ Î»°±®¬Ø¿²»² Ì¸±®° Ð»´´·²»² Ñ´±²ô ×²½ îððë Í¬®»»¬ ×³°®±ª»³»²¬ Ð®±¶»½¬Ò±ò ðëóðï The desired pavement life of these roads is approximately 15-20 years. The alternative that satisfies the needs of the City in the most economical manner is a combination of Option #1 and Option #2. The level of transverse cracking on Foxford Road and Pine View Court is minor enough that the areas of full depth mill and patching required will be minimal. Full reconstruction with curb and gutter is not proposed at this time because utility extensions are currently planned for the year 2020. This work will not be performed until utilities are extended. Option #1 is the desired alternative for Foxford Road and Pine View Court. However, the condition of the pavement on Eastwood Court is in such a level of distress that areas requiring full depth mill and spot patching will cost more than if a full depth mill and overlay were performed on the contiguous length of roadway. Option #2 is the best alternative for Eastwood Court. The preferred combination of Options #1 and #2 are presented in the Preliminary Cost. Estimate found in Appendix A. However, since the cost for Option #2 is very close to the cost for Option #1, it is recommended to bid Option #2 as an alternate to Option #1. Refer to Figure 2, Sheet 3 for the proposed street improvements to the Foxford Road Area. The costs associated with the street improvements will be assessed per the City’s Standard Assessment Practice as found in Appendix C. Deerbrook Drive Deerbrook Drive has been identified as requiring pavement rehabilitation through the Pavement Management System. The pavement has severely deteriorated primarily due to the fact that there is no crown evident on the roadway. The water sits on the road and penetrates the surface creating the transverse cracking and rutting in the pavement. Option #1: Pavement rehabilitation will include a 1–1/2-inch deep edge mill of the existing pavement and a full depth mill and patch in areaswhere severe transverse cracking exists. A 2-inch deep overlay of the roadway will be performed to provide a more defined crown section on the road. This will allow the water to flowoff the road and into the existing ditch system. Option #2: Pavement rehabilitation will include a full depth mill of the existing pavement. The milled bituminous will be reclaimed to shape thesubgrade to allow a full depth overlay to be performed to provide a more defined crown section on the road. This will allow the water to flow off the road and into the existing ditch system. The desired pavement life of these roads is approximately 15-20 years. The advantage of Option #2 over Option #1 is that the level of distress of the existing pavement on Deerbrook drive is such that the area requiring full depth mill and spot patching will cost more than if a full depth mill and overlay were performed on the contiguous length of roadway. This translates to a savings in assessments while also meeting the desired 15-20 year life cycle. Full reconstruction with curb and gutter is not proposed at this time because utility extensions are currently planned for the year 2020.

Option #2 is the preferred option for Deerbrook Drive and is thus presented in the Preliminary Cost Estimate found in Appendix A. Refer to Figure 2, Sheet 3 for the proposed street improvements to Deerbrook Drive. The costs associated with the street improvements will be assessed per the City’s Standard Assessment Practice as found in Appendix C. Meadowlark Lane Meadowlark Lane has been identified as requiring pavement rehabilitation. The pavement has severely deteriorated primarily due to the fact that there is no crown evident on the roadway. The water sits on the road and penetrates the surface creating the transverse cracking and rutting in the pavement. Option #1: Pavement rehabilitation will include a 1–1/2 inch deep edge mill of the existing pavement and a full depth mill and patch in areaswhere severe transverse cracking exists. A 2-inch deep overlay of the entire road will be performed to reestablish a crown section on the road. This will allow the water to flow offthe road and into the existing ditch system. Option #2: Pavement rehabilitation will include a full depth mill of the existing pavement. The milled bituminous will be reclaimed to shape thesubgrade to allow a full depth overlay to be performed to reestablish a crown section on the road. This will allow the water to flow off the road and into the existing ditch system. The desired pavement life of these roads is approximately 15-20 years. The level of distress in the pavement is less than adjacent roads and this translates to a total cost difference of $9,375 or approximately $400 per lot in assessments while also meeting the desired 15-20 year life cycle. Full reconstruction with curb and gutter is not proposed at this time because utility extensions are currently planned for the year 2020. This work will not be performed until utilities are extended. Option #1 is the preferred option and is thus presented in the Preliminary Cost Estimate found in Appendix A. Since the cost for Option #2 is very close to the cost for Option #1, it is recommended to bid Option #2 as an alternate to Option #1. Refer to Figure 2, Sheet 3 for the proposed street improvements to the Meadowlark Lane. The costs associated with the street improvements will be assessed per the City’s Standard Assessment Practice as found in Appendix C.

This area has been identified as requiring pavement rehabilitation. The pavement has experienced cracking and rutting of the existing surfacing. The existing storm sewer system contains 3 catch basins, but serves a relatively large area, including the City Hall play fields and the City Hall parking lots which do not have any catch basins. Option #1: Pavement rehabilitation will includea 1-1/2-inch deep edge mill of the existing pavement and a full depth mill and patch in areaswhere severe transverse cracking exists. A 2-inch deep overlay of the entire road will be performed to provide a more defined crown section on the road. This will allow the water to flowoff the road and into the existing storm system more efficiently. In addition, storm sewer will be extended north to serve the City Hall play fields and City Hall parking lots. This will require that catch basins be added to Chan View with curb and gutter replacement. Concrete sidewalk will be added to the corridor where none exists. Option #2: Pavement rehabilitation will include a full depth mill of the existing pavement. The milled bituminous will be reclaimed to shape thesubgrade. A full depth overlay of the entire road will be performed to provide a more defined crown section on the road. This will allow the water to flow off the road and into the existing storm sewer system more efficiently. The desired pavement life of these roads is approximately 15-20 years. The advantage of Option #1 over Option #2 is that the level of distress in the pavement is not significant. The proposed improvements also meet the desired 15-20 year life cycle. Option #1 is the preferred option and is thus presented in the Preliminary Cost Estimate found in Appendix A. Refer to Figure 2, Sheet 4 for the proposed street improvements to Chan View. The costs associated with the street improvements will be assessed per the City’s Standard Assessment Practice as found in Appendix C. Assessments will be based on a front foot cost along the street that is being improved. This has been determined to be the fairest option. City Hall Parking Lots The east City Hall parking lots are recommended for rehabilitation at this time. The condition of the existing pavement located in the northeast lotis experiencing block cracking of the pavement surface. The pavement distress in the north lot isdue primarily to the fact that there is no storm sewer system in the lot. The water drains across the lot through a swale located in the center of the lot. The watershed from the Elementary school field drains onto the north lot through the existing swale. This drainage pattern has caused significant amount of ice to form in the lot and City of Chanhassen,MNHTPO, Inc. 13 Ð®»´·³·²¿®§ Ú»¿·¾·´·¬§ Î»°±®¬Ø¿²»² Ì¸±®° Ð»´´·²»² Ñ´±²ô ×²½ îððë Í¬®»»¬ ×³°®±ª»³»²¬ Ð®±¶»½¬Ò±ò ðëóðï has became a hazard for city employees and thepublic. There are also areas of cracked and settled concrete curb and gutter in the north lot. The south City Hall parking lot has seen a significant amount of construction traffic from the recent park improvement and library projects. This has caused pavement distress. The proposed rehabilitation will include a 1-1/2-inch deep mill and overlay of the pavement in the south and north lots. Storm sewer will be extended into the play fields to minimize runoff into the parking lot. Catch basins will be added to capture the water that would otherwise flow over the pavement and onto Market Boulevard. Minor grading and reshaping of the pavement to ensure a grade of at least 0.5% will be provided to direct the water into the proposed catch basins. Cracked curb and gutter sections will be removed and replaced. The cost of the rehabilitation to the City Hall parking lots will be paid for with City funds and are thus not included in the assessment roll. The costs for the proposed improvements are detailed in the Preliminary Cost Estimate found in Appendix A. Refer to Figure 2, Sheet 4 for the proposed street improvements to the City Hall parking lots. Fire Station Parking Lot The condition of the existing pavement located in the Fire Station parking lot is experiencing block cracking, alligatored pavementand rutting at the driveway to the east garages. Most of the pavement failures are due to the extreme load that the fire trucks place on the pavement. The concrete driveway apron is also cracked and has settled. Areas of the parking lot currently do not have curb and gutter. The proposed improvements include placement of approximately 1,000 square feet of concrete pavement in the areas where the fire trucks drive, replacement of the cracked concrete driveway apron, and replacement of the cracked curb and gutter. Concrete curb and gutter will be added at locations where none exists. A 1-1/2-inch deep mill and overlay of the remainder of the existing bituminous pavement will be performed. The cost of the rehabilitation to the Fire Station parking lots will be paid for with City funds and are thus not included in the assessment roll. The costs for the proposed improvements are detailed in the Preliminary Cost Estimate found in Appendix A. Refer to Figure 2, Sheet 4 for the proposed improvements to the Fire Station parking lot.

MAINTENANCE: (Pothole filling, Patching,cracksealing, seal coat) Maintenance costs are not assessed to abutting property owners. Maintenance costs are financed through the City’s Annual Budget process. REHABILITATION: (Repair of problem areas to full depth,Milling of edge or full width of existingpavement, Repairtoexisting catch basins and/or curb and gutter, Pavement Overlay) Rehabilitation costs are assessed using the following formula: Total Project Cost = 60% Paid by City +40% Assessed to (City share may be MSA, General abutting Property Fund, TIF, Federal or State Grants, Owners etc.) Residential properties that abut collector or commercial streets shall be assessed using the same formula, however, the assessments shall be reducedto be equivalent to a typical 31’ residential street section. RECONSTRUCTION: (Removal of existing street and construction of new street,. May include sanitary seweror watermain work, May recycle the existing asphalt as gravel base) Reconstruction costs are assessed using the same formula as Rehabilitation. NEW CONSTRUCTION: (Construction of new street or utilities or a significant upgrade from the previous facilities. i.e. a 4-lane street replacesan existing 2-lane.) New Construction will be assessed 100% to the benefiting properties. NOTE: If a feature (sanitary sewer, water,curb and gutter, etc.) that did not previously exist is added during a rehabilitation or reconstruction, the cost of that item is treated as new construction with the remaining project costs being treated as rehabilitation or reconstruction. WORK DONE BY CITY CREWS: Work done by City Crews may be maintenance, rehabilitation, or new construction. This work is not typically assessed. Exceptions would include work associated with an assessment agreement signed by the property owner and approved by the City Council and work specifically authorized by the City Council to be done by City Crews and assessed to the abutting properties. g:\eng\forms\assessments\assessment practices.doc
