DISCUSSION Attached is a final draft of the feasibility study for this project. The following changes have been made from the draft previously received: Discussion of the South Shore neighborhood has been removed from this feasibility study for budget reasons. This area will be reconsidered at a future time. Indirect costs were left out of the cost estimates in the previous study. Indirect costs include financial, legal, administration, and engineering costs. Both the cost estimate and the assessment rolls have been adjusted to include these costs. 3. Tables have been added to better show the funding for this project. 4. Minor typographical errors have been corrected. Staff recommends that to reduce confusion, Council call property owners by street for the public hearing with a brief introduction of the existing condition and proposed improvements by staff as each street is called. Market Boulevard (between Highway 5 and W, 78th Street) The existing surface shows moderate deterioration evidenced by cracking both transverse (across the width) and longitudinally (lengthwise) on the street. The consultant is recommending the full width of the street be milled an average of 1Va" and a bituminous overlay be placed to rehabilitate the existing surfacing and extend the life of the street.

A cost to replace this mat has been included in the cost estimates for the project. West 78th Street (between Market Boulevard and Great Plains Boulevard) The pavement in this area shows signs of deterioration, but still appears structurally sound. The consultant is recommending the full width of the street be milled an average of 1V2" and a bituminous overlay be placed to rehabilitate the existing surfacing and extend the life of the street. Cracks that extend through the milled section will be sealed prior to the overlay. In addition, slope and curb adjustments should be done at the same time to improve storm drainage in the area. Traffic signal loop detectors at Market Boulevard, Laredo Drive, Great Plains Boulevard and Highway 101 will need to be removed and replaced as part of the project. At the same time this project is done, the unused driveway openings into the cemetery will be removed and replaced with curb and gutter similar to that currently in place. West 79th Street (between Market Boulevard and Great Plains Boulevard and Great Plains Boulevard to the cul-de-sac) These roads are not currently on the City's Municipal Street Aid System (MSAS). The section between Market Boulevard and Great Plains Boulevard qualifies to be placed on the MSAS system in which case, staff recommends that the project be pursued at this time. The section between Great Plains Boulevard and the cul-de-sac do not meet the criteria for MSAS inclusion. Todd Gerhardt September 16, 2003 Page 3 The pavement between Market Boulevard and Great Plains Boulevard shows evidence of moderate deterioration similar to that on the other streets. The section approximately 450' east of Market Boulevard shows significant failure that appears to have been caused by the storm sewer pipe heaving, possibly due to poor bedding of the pipe during installation. The pavement in this area will need to be removed and the storm sewer pipe reinstalled properly to minimize potential damage from future frost heave. The section east of Great Plains Boulevard was widened and resurfaced in 1991 and could be delayed until future construction. The consultant is recommending the full width of the street be milled an average of lY2" and a bituminous overlay be placed to rehabilitate the existing surfacing and extend the life of the street. Cracks that extend through the milled section will be sealed prior to the overlay. In addition, it has been recommended that a sidewalk be considered along the north side of W. 79th Street. Staff will work with the property owners to determine if this is feasible and desirable to all of the impacted property owners and if so, prepare an addendum to the feasibility study with revised assessments for the impacted property owners as per the City's Assessment Practice. FUNDING This project is proposed to be funded with a combination of MSAS State-Aid, State Turn-Back Funds, and assessments. c: Jason Sprague, SEH g:\eng\public\04-02Xstaff report 9-16-03.doc Report on Feasibility 2004 MSA Street Improvements Chanhassen, Minnesota City Project No. 04-02 SEH No. A-CHANH0308.00 September 15, 2003 2004 MSA Street Improvements Report on Feasibility Chanhassen, Minnesota City Project No. 04-02 SEH No. A-CHANH0308.00 September 15, 2003 I hereby certify that this report was prepared by me or under my direct supervision, and that I am a duly Licensed Professional Engineer under the laws of the State of Minnesota.

However, they do require a significant amount of maintenance to extend the serviceable life of the respective roadways. The present age of the roadway, proposed traffic volumes, and natural weathering factors indicate that a mill and overlay should be performed on Market Boulevard, Great Plains Boulevard, and West 78th and 79th Streets. Surface drainage problems exist at several locations in the project area, and are addressed within the context of this report. Sporadic concrete curb and gutter replacement and catch basin reconstruction is necessary throughout the entire project area. o There is adequate pedestrian access throughout a majority of the project area. However, 5-foot sidewalk connections are proposed on the east-side of Market Boulevard between Highway 5 and West 79th Street and on the west-side of Great Plains Boulevard between West 79th Street and the existing sidewalk to the north. Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 1 1.2 4. Valley gutters are proposed to facilitate improved drainage at driveways and/or intersections with relatively flat grades. o SEH has identified locations where the existing concrete curb and gutter has deteriorated to a condition that warrants removal and replacement due to frost heave, settlement, snow plow impacts, etc. 6. The improvements are necessary, cost-effective, and feasible. Recommendations It is recommended that: 1. The report be reviewed by the City Council, staff, and financial advisors. 2. Reconstruction of the streets in 2004 MSA Street Improvements project area should proceed at an estimated cost of $961,501.63. 3. The project be financed with MSA funds, special assessments, and State Turnback funds. The City Council pledge MSAS funding of SIM and State Turnback funding of $250,000 to fund the City's share of the project. o Meet with adjacent residents and property owners to discuss the existing conditions, such as drainage issues, parking/no parking locations and/or pedestrian access, and identify the proposed improvements. 6. The City should continue budgeting funds to finance future street maintenance costs. 7. Construct the improvements as proposed in this report. Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 2 2.0 Introduction Background Information A report on feasibility for the 2004 MSA Street Improvements was ordered by the Chanhassen City Council in May 2003. The study area is shown on the following map. The streets included in this study are Market Boulevard (MSA), Great Plains Boulevard (MSA), West 78th Street (MSA and State Turnback), and West 79th Street (local street). This project is considered part of the City of Chanhassen's ongoing annual street improvement program. Before initiating this feasibility study, SEH work plan to outline the scope of the study. analyzed in this feasibility study are: coordinated a detailed The work components 1. Examine the existing condition of the bituminous pavements in the project area. 2. Analyze the existing concrete curb and gutter for cracking and/or settlement and quantify locations where replacement is necessary. 3. Identify 'fiat spots' or other locations in the roadway with inadequate drainage which lead to street ponding. 4. Identify catch basin structures that have heaved or settled. Propose reconstruction strategy for these locations. 5. Identify existing sidewalk locations, pedestrian accessibility, and system continuity, and suggest improvements where necessary. o Determine locations where safety improvements may be made, such as the addition of surmountable medians, removal of unused access points, etc. 7. Examine the feasibility of installing a drain tile system to serve areas where deemed necessary. 8. Analyze the existing railroad crossings at Great Plains and Market Boulevard and determine if any improvements are necessary. The report figures are located at the end of this report. Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 3 Project Location Map Feasibility Report for Project No. 04-02 SEH No, A-CHANH0308.00 Chanhassen, Minnesota Page 4 3.0 3.2 Existing Conditions Pavement The streets in the project area were either originally constructed or reconstructed in a span of time beginning in the mid 1970s to the early 1990s. For this reason, the pavement conditions vary from street to street. However, there were no locations in the project area that necessitated complete reconstruction of the roadway. The present pavement surfaces show signs of only moderate deterioration. A site visit to the project area confirmed that a majority of the street pavements are in relatively good condition. SEH analyzed the streets in the project area and used the following conditions and criteria for evaluation: Bituminous pavement is designed to last 25 to 30 years, based upon the latest construction and maintenance procedures used in the City of Chanhassen. Extensive cracking was not noted in any location within the study area. Such cracking, also identified as 'alligator cracking' is a sign of imminent structural failure and the last step prior to a pothole developing. The streets in the study area only showed signs of minor transverse and longitudinal cracking, a problem easily solved with a proactive maintenance policy. In specific locations, improperly bedded pipes beneath the roadway will result in unintentional 'speed bumps' in the road surface. In these locations, the pipes will need to be excavated and the road reconstructed to provide a suitable driving surface. In some locations, the streets have settled, resulting in 'bird baths' after rainfall or snow-melt events. In addition, the crown of the street has subsided in some locations, allowing surface water runoff to flow randomly down the street and not into the gutter. Both of these conditions contribute to more water soaking into the underlying soils through cracks in the surface. The water will subsequently weaken the soils, which will eventually lead to structural failure if not corrected by restoring positive drainage. Progressively increasing traffic volumes and weathering were other factors that contribute to the ongoing deterioration of the pavement surface. Sidewalks A rather extensive sidewalk system presently exists in the project area. Pedestrian access is provided on at least one side, and in several cases, both sides of the streets. Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 5 3.3 3.4 At present, there are some locations in the project area that are conducive to sidewalk connections and pedestrian flow, however, no sidewalk exists. These areas have been identified on the east side of Market Boulevard between Highway 5 and 79th Street, and on the west side of Great Plains Boulevard from 79th Street north to the existing sidewalk. Most sidewalk connections with the streets in the project area utilize ADA-compliant pedestrian ramps for handicapped access. However, the sidewalk on the north side of 79th Street, approximately 600 feet east of Market Boulevard does not presently have pedestrian ramps at the driveway intersections. Right-of-Ways and Easements The streets within the study area are built approximately in the center of the right-of-ways (ROW). The majority of the ROW in the project area is between 70 and 100 feet wide. As a majority of the work proposed in this feasibility study will occur on the existing roadway surface, the ROW corridor will be sUfficiently wide for all of the work proposed in this study. Drainage Two types of drainage have an impact in the study area. The first type - surface water runoff- results from rainfall or snow melt. The project area relies heavily upon the concrete curb and gutter section to transport water catch basins and on to the adjacent drainage ponds. Unexpected settlements in the curb and flattening of the road profile leads to the creation of 'bird baths' on the road surface where surface water runoff does not reach the intended catch basins. Consultation with City staff and a subsequent field investigation identified the following potential surface water runoff problems: Potential drainage problems due to heaved storm sewerthPipe and catch basins near the existing low point on 79 Street, approximately 400 feet east of the intersection with Market Boulevard. 2. Indications of standing water at the intersection of Market Boulevard and Pauly Drive. 3. Several individual low spots in the outside and median gutters on 78th Street between Market Boulevard and Great Plains Boulevard. 4. Standing water at the east-side of the 78th Street and Highway 101 intersection. Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 6 o Large tributary area draining to the Lotus Lake Park parking lot, in addition to erosion problems at the storm sewer inlet on the northeast comer of the parking lot. The second type of drainage affecting the study area is subsurface or groundwater flow. At present, we have no soil borings in the project area to confirm the elevation of the water table, or the type of soils encountered in the area. 3.5 Utilities The sanitary sewer and water main systems have been in place since the mid 1970s to the late 1980s. Several utility improvement projects have been completed in the project area since the time of their original construction. The existing sanitary sewer throughout the project area is periodically televised, and initial discussions with City staff have indicated no significant issues at this time. There are no known problems with the water main system that needs to be corrected with the street reconstruction. The condition of sanitary sewer services from the main to the houses is not known at this time. Although there have been no issues identified by City staff or property owners at this time. Electric, telephone, and cable TV lines in the study area are mostly buried outside of the street pavement area. There are some overhead utilities in the project area, however, they should not create any problems with any of the proposed improvements identified in this study. Gas mains and services are buried under the street pavement and no significant problems have been identified with these lines. 3.6 Concrete Curb and Gutter A large majority of the concrete curb and gutter on Market Boulevard, 78th Street (west of Great Plains Boulevard), and Great Plains Boulevard is a modified version of B612 (median) and B618 (outer curb). The modified version is different from the typical variety because it has a thicker section of concrete at the top of the curb. A normal B-type curb is six inches thick at the top and eight inches thick at the gutter line. The curb section on the aforementioned streets is approximately 10 inches thick at the top and 12 inches thick at the gutter. This thicker section has provided for additional structural strength as much of this curb section is in very good condition and shows very few mid-panel cracks. However, as found at several locations within the project area, the modified B612/B618 curb and gutter sections have settled/faulted Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 7 adjacent to a few of the existing catch basin structures on Market Boulevard. The concrete curb and gutter on 78th Street, east of Great Plains Boulevard, and 79th Street, east of Great Plains Boulevard is a standard B612/B618. Although this curb is in relatively good condition, some sections have settled/heaved near the existing catch basins. In addition, a minimal amount of curb has shown signs of mid-panel cracking. The curb on 79th Street, between Market Boulevard and Great Plains Boulevard is a surmountable D-type curb. The curb in this location has shown some signs of minor deterioration and settlement near the existing catch basins. In addition, there is an incomplete valley gutter crossing 79th Street at Great Plains Boulevard. It should also be noted that on both Market Boulevard and Great Plains Boulevard approaching Highway 5, and on 78th Street approaching Highway 101, the concrete curb and gutter section transitions into a B624 type, as is typical on Mn/DOT projects. Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 8 4.0 4.2 Criteria for Investigation Criteria The criteria for improvements proposed in this report include: 1. City of Chanhassen standards for street and utility construction. 2. Minnesota Department of Transportation (Mn/DOT) State Aid street standards. 3. City of Chanhassen standard assessment policies. Permits The improvements proposed in this report will require review and permit approval from the following agencies: 1-.Minnesota Pollution Control Agency (NPDES) and Watershed District for grading and drainage. 2. Mn/DOT State Aid streets. 3. Twin City and Western Railroad Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 9 5.0 Proposed Improvements Pavement The proposed improvements to the pavement sections vary by location for this project. A common preventative maintenance approach for roads with minor to moderate deterioration is a mill and overlay procedure. In this process, a specified depth of the existing pavement is removed, or milled off. Upon removal of the existing pavement surface, all of the remaining cracks are sealed to prevent moisture penetration into the roadway subgrade. A new bituminous asphalt overlay is then placed to seal the roadway and match existing grades. This maintenance process is used to provide a new driving surface for the roadway while improving driver 'rideability' and rebuilding the centerline crown to facilitate better drainage. A 1½-inch depth mill and bituminous overlay is proposed for the following segments: 1. Market Boulevard- between Highway 5 and 78th Street 2. Great Plains Boulevard- between Highway 5 and 78th Street 3. West 78th Street - between Market Boulevard and Great Plains Boulevard 4. West 79th Street - betWeen Market Boulevard and Great Plains Boulevard. This work could be delayed for a couple of years as this section cannot be added to the City's MSA system. However, there is a potential cost savings by combining this project with the larger Market Boulevard, Great Plains Boulevard, and West 78th Street project. 5. West 79th Street- from Great Plains Boulevard to the cul-de- sac terminus. This section does not qualify for inclusion in the City's MSA system, which means the City share of the project would need to withdrawn from the General Fund. This section of roadway could be delayed for a couple of years, and combined with a future project funded with General Fund dollars. However, there is a potential cost savings by combining this project with the larger project, especially if West 79th Street is completed in 2004. In locations where the pavement has deteriorated to a more significant extent, the existing pavement and roadbed will be ground into a recycled base material that will be used under the proposed pavement Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 10 structure. This type of improvement is proposed only for spot repairs on the above streets. 5.1.1 Market Boulevard In general, the pavement surface in this segment shows evidence of moderate deterioration. This is characterized by minor transverse and longitudinal cracking. Based upon our field observations and our study of the existing and proposed traffic volumes, we recommend a full-width, 1½-inch mill and bituminous overlay as the appropriate rehabilitation strategy. In addition, any cracks remaining upon completion of the milling operation will be sealed to minimize any moisture penetration to the subgrade material. The traffic signal loop detectors at the intersections of Market Boulevard with Highway 5 and 78th Street are typically removed and/or significantly damaged during the milling operation. The loop detectors will be replaced in conjunction with the paving of the bituminous wear course. The existing pavement markings and traffic control have been documented during our field investigation. These markings will be further analyzed during the design phase of the project to determine if any revisions to the existing pavement markings are necessary. The existing pavement markings will be replicated and replaced with new epoxy pavement markings upon completion of the final wear course. An analysis of the Twin City and Western Railroad crossing with Market Boulevard has determined that the existing lighting and crossing signals are adequate for the intersection. However, the rubber-matted material between the railroad tracks is nearing the end of its functional life and should be replaced in conjunction with this project. An estimated cost for the removal and replacement of the rubber mat and related materials at the crossing, has been included in the overall cost estimate as found in the Appendix. 5.1.2 Great Plains Boulevard The pavement surface in this segment also shows evidence of moderate deterioration. The transverse and longitudinal cracking is similar to that found on Market Boulevard. Based upon our field observations and our study of the existing and proposed traffic volumes, we recommend a full-width, 1½-inch mill and bituminous overlay as the appropriate rehabilitation strategy. The remaining cracks will be sealed to minimize any moisture penetration to the subgrade material. The traffic' signal loop detectors at the intersections of Great Plains Boulevard with Highway 5 and 78th Street will be removed and/or significantly damaged during the milling operation. The loop Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 11 5.1.3 detectors will be replaced in conjunction with the paving of the bitmninous wear course. The existing pavement markings and traffic control have been documented during our field investigation. These markings will be further analyzed during the design phase of the project to determine if any revisions to the existing pavement markings are necessary. The existing pavement markings will be replicated and replaced with new epoxy pavement markings upon completion of the final wear course. An analysis of the Twin City and Western Railroad crossing with Great Plains Boulevard has determined that the existing lighting and crossing signals are adequate for the intersection. However, the rubber-matted material between the railroad tracks is nearing the end of its functional life and should be replaced in conjunction with this project. An estimated cost for the removal and replacement of the rubber mat and related materials at the crossing, has been included in the overall cost estimate as found in the Appendix. West 78th Street The bituminous surface in this location shows signs of deterioration, but the pavement appears to be structurally sound. We recommend a full-width, 1 ½-inch mill and bituminous overlay, with related Crack repair, as an appropriate rehabilitation strategy in this location, in conjunction with slope and curb adjustments to improve storm drainage. This will be discussed in greater detail in Section 5.4 Drainage, of this report. Traffic signal loop detectors at the intersections of 78th Street with Market Boulevard, Laredo Drive, Great Plains Boulevard and Highway 101 will be removed and/or significantly damaged during the milling operation. The loop detectors will be replaced in conjunction with the paving of the bituminous wear course. On the segment of 78th Street, approximately 700 feet east of the intersection with Great Plains Boulevard, there are several unused driveway aprons on the south side of the roadway that were originally used to access the cemetery adjacent to 78th Street. These aprons will be removed in conjunction with this project, and replaced with B618 curb and gutter. The existing pavement markings and traffic control have been documented during our field investigation. These markings will be further analyzed during the design phase of the project to determine if any revisions to the existing pavement markings are necessary. The existing pavement markings will be replicated and replaced with new epoxy pavement markings upon completion of the final wear course. Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 12 5.1.4 West 79th Street There are two segments of 79th Street studied within the context of this report. The first is bound by Market Boulevard on the west and Great Plains Boulevard on the east. The other segment begins at Great Plains Boulevard and extends east and terminates in a cul-de-sac approximately 700 feet to the east. On the segment between Market Boulevard and Great Plains Boulevard, the most significant problem with the pavement exists approximately 450 feet east of Market Boulevard. A poorly bedded storm sewer pipe has heaved into the roadbed and created a 'hump' in the pavement surface. The pavement in this section will need to be removed and the storm sewer pipe and structures will need to be salvaged and replaced on appropriate bedding material to minimize any potential damage from frost heave. This entire procedure will necessitate the complete reconstruction of about 200 feet of roadway on 78th Street. The remainder of this segment has shown moderate signs of fatigue in the form of transverse and longitudinal cracking of the driving surface. We recommend a full-width, 11A-inch mill and bituminous overlay, with related crack repair, that matches into the reconstruction segment. The segment east of Great Plains Boulevard is in relatively good condition. According to the as-built plans on file with the City, this segment was widened and resurfaced in 1991. The low traffic volumes and recent improvements have contributed to the limited deterioration on this segment and have minimized the need for rehabilitation at this time. However, due to the adjacent construction proposed in this study and the timeline for future maintenance activities in this location, the City may elect to rehabilitate this segment of 79th Street at this time. If so, a 1½-inch mill and overlay would preserve the existing pavement structure for up to ten years. 5.2 Sidewalk Upon inspection of the existing sidewalks adjacent to the roadways in the study area, they have been found to be in relatively good condition. Therefore, a majority of the proposed improvements related to the sidewalks consist of the construction of new sidewalks and/or modifying access to an existing sidewalk. Sidewalks are not required by MSA standards, but are eligible for MSA funding if included. Thus, a 5-foot concrete sidewalk will be constructed on the east-side of Market Boulevard from Highway 5 to 79th Street. A sidewalk will also be constructed from the existing pedestrian ramp in the northwest quadrant of the intersection of Great Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 13 5.3 5.4 5.4.1 Plains Boulevard and 79th Street, extending north to connect with the existing sidewalk. The proposed sidewalk sections will consist of 4 inches of aggregate base material and 4 inches of concrete pavement. On the north side of 79th Street, approximately 800 feet east of Market Boulevard, there is a relatively new sidewalk on the north side of the street. This sidewalk has been constructed to the back of the existing barrier curb, not allowing for handicapped access. The existing barrier curb will be removed, and a ADA-compliant pedestrian ramp will be constructed on the east and west end of the sidewalk. Rights-of-Ways and Easements All proposed improvements identified in this feasibility study should be within the existing right-of-way (ROW) limits. No temporary or permanent easements are anticipated at this time. Drainage The reuse of the existing storm water collection system is a principle component of the proposed improvements identified in this study. However, some of the existing catch basins have heaved into the surrounding concrete curb and gutter, creating drainage problems and allowing storm water to penetrate the subgrade soils, creating additional problems. Proposed correction of this problem will include adjusting the catch basin casting heights and/or curb and gutter replacement, where necessary. Other drainage improvements will be focused on alleviating areas with poor drainage, where existing ponding of runoff is evident. These improvements will include re-grading the roadway where necessary and the installation of concrete valley gutter at selected intersections to convey runoff to the existing catch basins. Market Boulevard Preliminary analysis has identified the intersection of Market Boulevard with Pauly Drive as a location that is relatively flat. Our field investigation and subsequent topographic survey has indicated that this location would benefit by the construction of an additional catch basin structure on the east and west side of the intersection to provide adequate drainage. These catch basins would be tied into the existing system, which ultimately drains into the storm water pond in the northwest quadrant of Market Boulevard and Highway 5. In addition, the existing valley gutter on both sides of the intersection should be removed, the subgrade adjusted to drain to the new catch basin structures, and replaced in order to facilitate the flow of the storm water. Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 14 5.4.2 Great Plains Boulevard There were no significant drainage problems identified on Great Plains Boulevard. 5.4.3 West 78th Street The two commercial driveways on the north side of 78th Street between Laredo Drive and the west intersection of 78th Street with Great Plains Boulevard would benefit by the addition of a valley gutter across the driveway. At present, there is evidence of ponding in the gutter line on both of these driveways. In addition, there are several low spots in the outer and median gutter on 78th Street between Market Boulevard and Great Plains Boulevard. Most of these low spots appear to be caused by curb that has heaved and/or settled. These curbs can be repaired either by 'mud-jacking' the existing curb, or removing and re-pouring the unsuitable curb sections. Moving east from the intersection with Great Plains Boulevard, there are three driveway entrances to the cemetery on the south side of 78th Street that are presently unused. These driveway aprons will be removed and replaced with standard B618 curb and gutter. The most troubling drainage issue on 78th Street occurs immediately west of the intersection with Highway 101. Existing drainage in the north curb-line of 75th Street is conveyed to the existing catch basin approximately 150 west of the intersection. However, any storm water to the east of this catch basin drains to the northwest corner of the intersection. As it pools in this gutter, it eventually overflows across 78th Street to the south and pools in the north gutter of the intersection 'pork-chop' island. Drainage pools in this location until continuing on to the south, across the 'free-right' turn lane, and into an existing catch basin. Additional discussion with the City is necessary to determine the extent of the existing problem in this area. A field investigation has determined that ponding does occur in each of the areas identified above, however, the typical depth and duration are not known at this time. Additional as-built plans have presently been requested from Mn/DOT for this location in order to ascertain invert elevations on the existing catch basins. One proposed solution would add a catch basin structure in the northwest comer of the intersection and connect it to the catch basin 150 feet to the west. However, the as-built information will be necessary to determine if this is feasible. Upon further discussion with City staff, SEH will evaluate if any improvements are necessary in this location and additional alternatives will be evaluated during the design phase of this project. Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 15 5.4.4 5.4.5 5.5 5.6 West 79th Street The only significant drainage problem identified on 79th Street occurs at the low point approximately 400 feet east of the intersection with Market Boulevard. The existing storm sewer pipe crossing 79th Street and extending to the storm water pond to the south, has heaved into the existing pavement creating an 'unintentional' speed bump in the road. This pipe, subgrade, and related catch basins will need to be excavated and replaced with granular bedding material, compacted, and replaced. If possible, the profile will be adjusted to lower the Iow point in this location, which will necessitate the reconstruction of approximately 200 feet of roadway to accommodate the profile revision. Lotus Lake Park Drainage A major drainage issue has been identified in the Lotus Lake Park parking lot. A large amount of runoff from the project area ends up in the parking lot, as it is the low point for a majority of the development. Additional discussions with City staff are necessary to determine whether Lotus Lake drainage improvements will be constructed in conjunction with this project. Utilities Due to the present condition of the sanitary sewer and water main in the project area, no improvements to the public utilities are proposed at this time. Private utilities such as electric, telephone, gas, and cable TV, will be notified of the impending potential improvement project and any proposed improvements to those facilities will be coordinated with the appropriate agency and constructed prior to the placement of the bituminous wear course and/or restoration of the sod. Concrete Curb and Gutter A detailed field review of the existing concrete curb and gutter conditions was performed to identify replacement areas with the objective of preserving as much existing concrete curb and gutter as possible. The criteria used to determine unacceptable curb was based on the following: 1. The curb needed to be removed if one major defect was found on a section, e.g., a faulted crack. 2. The curb needed to be removed if three minor defects were found on a section, e.g., several tight cracks and a scalloped curb face. Approximately five percent of the existing B-type curb was found to be in need of repair or replacement. The deteriorated curb was largely Feasibility Report for Project No. 04-02 SEH No. A-CHANH0308.00 Chanhassen, Minnesota Page 16 in the vicinity of the existing catch basins where the curb and gutter section has heaved/settled. A larger percentage of the D-type surmountable curb was found to be in poor condition. From our estimates, as much as 15% of the D-type curb on 79th Street between Market Boulevard and Great Plains Boulevard should be removed and replaced. The replacement curb and gutter will significantly improve drainage flow, maintain structural support to reduce edge deterioration, and continue to protect boulevards from traffic and snow plowing.

MAINTENANCE: (Pothole filling, Patching, crack sealing, 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 existing pavement, Repair to existing catch basins and/or curb and gutter, Pavement Overlay) Rehabilitation costs are assessed using the following formula: Total Project Cost: 60% Paid by City (City share may be MSA, General Fund, TIF, Federal or State Grants, etc.) 40% Assessed to abutting Property Owners Residential properties that abut collector or commercial streets shall be assessed using the same formula, however, the assessments shall be reduced to be equivalent to a typical 3 I' residential street section. RECONSTRUCTION: (Removal of existing street and construction of new street,. May include sanitary sewer or 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 replaces an 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\forlns\assessments\assessment practices.doc
