The proposed construction includes new concrete curb and gutter, street resurfacing, street reconstruction, and storm sewer improvements. Details are shown on Figures 2 through 4 at the back of this report. This J ro'ect is the result of the 1993 Comprehensive Street Report which examined the P P 1 surface condition and subsurface strength of each street in the project. The surface evaluation determined the Pavement Condition Index (PCI) which ranks each street Ibased on its condition. The subsurface strength evaluation determines a recommended structural improvements for a given axle loading based on a load applied to the existing 1 street. The 1993 Comprehensive Street Report addressed the needs for rehabilitating the older streets in the City. This project is the first of five recommended street resurfacing projects for Oak Park Heights. I All streets included under this project are streets which presently do not have concrete I P J P Y curb and gutter. New concrete curb and gutter will be installed as part of this project. The new concrete curb and gutter will improve drainage characteristics and prolong the life of the newly reconstructed streets. `'oi" Also included in this project are storm sewer improvements to collect drainage and reduce the amount of drainage carried in the gutter. These improvements consist of extending existing storm sewers to intersections where no drainage collection presently Iexists. Preparation of this report was authorized by the City Council on November 22, 1993 with Resolution #93-11-43. I 1 Oak Park Heights- 1994 Street Resurfacing Program 3 I \ 61st i 61st ST. N \ C ST.

The project can best be Icarried out as one contract. The contract will include 3.2 miles of residential streets and related utility improvements. I IStreet Evaluation Streets recommended for resurfacing and reconstruction are shown on Figure No. 2 I located at the back of this report. Appendix A and Figure No. 5, also located at the back of this report, summarize the results of the earlier Pavement Strength and Surface Evaluation Studies completed for the Comprehensive Street Plan. I Three items are considered in determining the condition of an existing street: I • Street age 2v y S �ac Q -i-ii -4_k"Li2;15 / - 2 51- 4-) I • Structural strength (recommended structural overlay thickness) nN?A� 1M IunS 1 • Surface Evaluation (PCI Ranking) In accordance with engineering standards, the recommended life of a street is 20 years, based on the anticipated life of the materials (aggregate base, bituminous, and concrete) used to build that street. However, many factors contribute to whether a street will function adequately beyond or less than a 20 year period. In the case of this project, the age of each street exceeds 16 years while many of the streets exceed 25 years. IThe desired minimum structural strength of a local street is 7 ton while a commercial collector street is 9 ton. As presented in Appendix A, a majority of the streets evaluated I require area repair or a bituminous overlay to meet the required axle loading. The recommended improvements are based on the subgrade condition and existing street section Effective Granular Equivalence (EGE). The desired granular equivalence for Oak Park Heights- 1994 Street Resurfacing Program 5 i Ia residential street is approximate 14 to 17. A¢ noted in Appendix A, many of the fr I EGE are below 17. In areas where t e 6 is below 14, some subgrade correction work will be necessary to improve the subgrade strength. IThe final and most important consideration in evaluating an existing street is the condition of its existing surface. The Pavement Condition Index (PCI) ranks the Icondition of each street surface. Figure No. 5 at the back of this report presents the PCI ratings for the streets in this project. Table 1 presents general categories to define PCI Rankings. I Table 1 - General Categories to Define PCI Rankings IPCI Condition of Street Maintenance 1 55-100 Good to Very Good Routine Crack Seal and Seal Coat C3-5-5_5_,Yyr Fair Major Repair Patch & Overlay I0-35 Very Poor Overall Repair (Reconstruction) IIn general, PCLraio,kings below 35 require removal of the existing bituminous pavement before constructing a new bituminous surface. The existing aggregate base may also ihave to be reconstructed (subgrade correction). PcI rankings between 35 and 55 , require bituminous surface removal or major patching before constructing a bituminous Ioverlay. P raking ar 55 h> ically do not require bituminous overlays and generally routine maintenance such as patching, crack sealing, and seal coats are cost effective. i As noted in Appendix A, and on Figure 5, many of the PCI rankings are below 55, while some of the PCI rankings are below 35. IBased on the PCI rankings for each street included in the project area, and the fact that new concrete curb and gutter is proposed, total removal of the existing bituminous is Irecommended. Some streets will require removal of the existing aggregate base and subgrade improvements as well. I H Oak Park Heights - 1994 Street Resurfacing Program 6 I I Discussion I IStreets All street resurfacing and reconstruction proposed under this project will be where no concrete curb and gutter presently exists. New concrete curb and gutter will be placed as part of the project. To effectively resurface these streets, a number of surface illpreparation steps must be taken prior to placement of the new concrete curb and gutter. Surface preparation includes the removal or milling of the existing bituminous surface. Subgrade correction (removal and reconstruction of the existing aggregate base and 1 II some subgrade) is required where the existing street section has failed. It is estimated that 35 to 40 percent of the existing streets will require some subgrade correction work. 1 Upon completing the concrete curb and gutter placement for each street, a new 3" thick II 11 bituminous surface will be constructed. Included in the paving process is the adjustment 1 111 of manholes and gate valves to the finished surface elevation. Finally, all necessary sodding and restoration is completed to restore the area to its original condition. I Proposed street improvements are shown on Figures 2 and 3 at the back of this report. i 1 Storm Sewer Included as part of the 1994 Street Resurfacing Program are storm sewer improvements Ias shown on the attached Figure No. 4. The storm sewer improvements include extensions to the existing storm sewer system to improve street drainage and provide greater inlet capacity. It is recommended the storm sewer be constructed at this time to to eliminate the need to disturb the street surface in the future to and to prolong the I life of the street. It is also recommended that the upstream drainage area from the end of the storm sewer system be no larger than 5 acres. 1 As part of the public notice process, the City may want to ask residents to state if they have sump pumps and where they presently discharge. It is hoped that the storm sewer extensions can reduce the number of sump pumps discharging to the sanitary sewers. HI Oak Park Heights- 1994 Street Resurfacing Program 7 I 1 Sanitary Sewer and Water Main IMiscellaneous sanitary sewer and water main repairs and replacements are included as part of this project. During the design phase, the City should consider televising the I sanitary sewer in the project area to determine if any major repairs are necessary. For the purposes of this report, we have estimated the amount of water and sewer repairs typically required for this type of project. Further review of these items will be completed during the final design for the project. I i Driveway Reconstruction IDue to the new concrete curb and gutter construction, driveway and boulevard restoration is required. Driveway restoration will include reconstructing the lower Iportion of the existing driveway to match the new concrete curb and gutter. Any disturbed portion of existing driveways will be reconstructed of the same material to an equal or better condition. I Easements and Permits The proposed construction will be completed within existing right-of-way and easements. In areas where narrow or questionable right-of-ways exist, construction will be limited to replacing the roadway to its existing width. Therefore, we assume that no additional 1 right-of-way or easements will be necessary. A permit from Mn/DOT will be required for the storm sewer between Oldfield Avenue and Olene Avenue along the T.H. 36 service road. 1 1 1 I I I I Oak Park Heights - 1994 Street Resurfacing Program 8 I I Area to be Included The area to be included for assessment purposes is listed in Appendix B and shown on Figure 6, located at the back of this report. Figure 7 presents a detail of the assessment area near Olinda and Olene Avenues. Properties in this area must be notified for the project hearings. I I I I I I I I I I I I Oak Park Heights - 1994 Street Resurfacing Program 9 I I Cost Estimate I IA detailed cost estimate is presented in Appendix C.

Overhead costs are estimated at 25% and include legal, engineering, administration, and bond interest. The estimated costs for sanitary sewer and water Imain are based on previous experience with similar projects. I I 1 I I I Oak Park Heights - 1994 Street Resurfacing Program 10 I Hi Assessments I IAssessments are proposed to be levied against the abutting benefited property. Assessment rates for street resurfacing/reconstructing are proposed to be levied based Ion the rate classifications shown below: 1 Assessment Rate Classifications Residential Curb (75% of total curb cost) ICommercial/Industrial Curb (75% of total curb cost) Residential Street (50% of total street costs) ICommercial/Industrial Street (50% of total street costs) Assessment rates will be determined based on the actual final P J ro'ect costs. Estimated I assessment rates in this report are based on the cost estiamtes in Appendix C. Residential property will be assessed on a unit (per lot) basis. Multiple residential will be assessed 0.6 of a residential unit for each multiple unit. Commercial/Industrial Iproperty will be assessed on a front foot basis. IThe assessable footage is determined in accordance with the Oak Park Heights Comprehensive Street. Plan. After reviewing this project, it was determined to assess I each lot an equal share of the project costs (on a per lot basis). Assessments are separated as "concrete curb and gutter" and "street resurfacing" to reflect different City participation for these two items. It is assumed, for purposes of this report, that storm Isewer extensions and sanitary sewer/water main repairs will not be assessed. IThe front foot rates are based on a total assessable footage of 24,870 feet. Assessable footages for commercial and City property are shown on Figures 6 and 7. IThe estimated assessment rates for the 1994 Street Resurfacing Program are presented in Table 3 below. Assessment rates presented herein will be revised based on final Iproject costs.

The final rates will be determined based on actual final costs. The calculations below can be followed when determining the final costs. I. Front Foot Rates for Commercial Property The front foot rates are determined by dividing the total project costs by the assessable front footage. Street: $894,600 _ 24,870 feet = $35.97/ft (Total) Assessment Rate is 50% of total: 0.50 * $35.97 = $17.99/ft. Concrete Curb: $459,800 _ 24,870 feet = 18.49 ft (Total) Assessment Rate is 75% of total: 0.75 * $18.49 = $13.87/ft. i There are a total of 1,630.41 assessable feet of commercial property. The total proposed assessments from commercial property (including the City Hall site) is: Street: 1,630.41 * $17.99 = $29,331.07 Curb: 1,630.41 * =$13.87 $22,613.79 I I 1 Oak Park Heights- 1994 Street Resurfacing Program D-1 1 II. Per Unit Rates for Residential Property P riY The per unit assessment rates are determined by dividing the total project costs, less the portion attributed to commercial property, by the total number of net residential units. The estimated net total project costs are: Street: $894,600 - 58,646 (commercial amount) _ $835,954 ' Curb: $459,800 - 33,146 (commercial amount) _ $426,654 ' There are a total of 279 net assessable units in the project. Therefore, the proposed unit rates are: Street: $835,954 _ 279 units = $2,996.25 (Total) Assessment Rate is 50% of total: 0.50 * $2,996.25 = $1,498.13 per unit Curb: $420,654 279 units = $1,529.23 (Total) ' Assessment rate is 75% of total: 0.75 * $1,529.23 = $1,146.92 per unit 1 1 1 1 I i Oak Park Heights- 1994 Street Resurfacing Program D-2 II _—.......---z.----- 0 el 40 o I 0 150 300 Seahr In NO ''', -s c (eV 03 ' ' 0 0 C 07 NOTE ' ..
