Based on these and the expense of 5 6 FEASIBILITY The 1997 Reconstruction Project is feasible. The following table summarizes the estimated costs of the proposed projects. SUMMARY OF ESTIMATED COSTS Construction Construction Total Cost Total Cost Cost Total Cost per foot per foot Street Reconstruction $939,500.00 $72.00 $1,268,480.00 $97.00 Storm Sewer $81,740.00 $6.00 $110,350.00 $8.00 TOTAL $1,021,240.00 $78.00 $1,378,830.00 $105.00 Note: The total construction cost per linear foot of the 1995 Reconstruction project in District A will be approximately$75.00 per linear foot compared to the cost shown above for$72.00. The costs for the 1997 Reconstruction Project are slightly higher than the costs stated previously in the 1993 Comprehensive Plan: 1993 Comprehensive 1997 Reconstruction Street Plan Feasibility Report Difference Total Project Cost $1,080,000 $1,378,830 $298,830 The increase in the project cost from the 1993 Comprehensive Street Plan is due to the addition of the following: • Storm sewer- the 1993 Comprehensive Street Plan did not include storm sewer costs and stated that these numbers would be evaluated with each individual project. • ParisAvenue/Beach Road - this is a county roadway. At the time the 1993 Comprehensive Street Plan was prepared the fate of this roadway was not certain. However, it is now the intention of the county to negotiate the turnback of this roadway to the city. As a part of this negotiation, an agreement will have to be reached regarding the amount of money the county will reimburse the city for the reconstruction of this street. It is important that Paris Avenue/Beach Road is reconstructed at the same time as the rest of the residential streets in Area D. Most residential streets in this area intersect this roadway, and the reconstruction of these intersections in conjunction with the rest of the streets will allow the new design to correct drainage problems. Also the residential streets can be designed to correctly tie into Paris Avenue/Beach Road which does not have curb and gutter but will have concrete curb and gutter when it is reconstructed. An additional benefit to reconstructing these roadways at the same time is the excess ground up bituminous from Paris Avenue/Beach Road can be used as aggregate base on other residential streets. 7 DESIGN RECOMMENDATIONS The following are the design standards recommended for this project. Street Section: The existing bituminous surface would be reclaimed (ground up) and recycled by using it as an aggregate base. Three inches of new bituminous would then be placed over an average aggregate base depth of 8 inches. This street section is illustrated in Figure No. 3. Street Width: The existing streets in Area D are 24' wide. The city's standard street width is 34', and the streets in Area A were reconstructed to this width. However, several of the streets in Area D have mature trees in close proximity to the street. Widening the street to 34' would require the removal of some of the trees and landscaping. Therefore, it is our recommendation that the majority of the streets be widened only to a width of 28'. This would provide for a minimum of an 8 foot parking lane on both sides of the road and a 12 foot driving lane. Please refer to page 6 of this report for the streets recommended to have widths of 24' or 32' instead of 28'. Curb: All curb will be concrete barrier curb (MNDOT B618). Storm Sewer: It is recommended that new storm sewer be installed where it will eliminate existing drainage problems and prolong pavement life by reducing ponding on the pavement surface. Figure 4 shows the proposed storm sewer for Area D. Driveways: All existing driveways will have concrete aprons installed. EXISTING UTILITIES Sanitary Sewer: The sanitary lines will be televised during the plan and specification phase of this project. The condition of the existing lines will not be known until that report is received. Water main,: Leak tests will be performed on the existing system to determine the condition of the existing lines. Storm Sewer: Visual inspections will be done on the existing system to determine if any repairs need to be made. None are anticipated at this time. 8 ASSESSMENTS / REVENUE The assessment policy as established by the city council for the 1995 Reconstruction Project was based on the following: • Each residential property will be assessed the same amount • This amount is based on the amount to be paid by the average size lot on this project • Commercial properties will be assessed on a front footage basis • The city of Stillwater should pay for half of the cost of the streets that lie half in Stillwater's city limits and half in Oak Park Heights city limits The assessment amounts are as follows: Residential Property in Oak Park Heights $2800/each Commercial Property in Oak Park Heights $33.80/front foot Stillwater Properties $56.50/ front foot There are 140 residential properties in Oak Park Heights to be assessed as part of this project. The total assessments for the project are as follows: Oak Park Heights Commercial Properties Property Assessable Assessment Footage St Croix Villas Condos 1087 $36,740 Church 330 $11,150 Orchard Park Condos 165 $5,580 TOTAL $53,470 9 Stillwater Properties Property Assessable Amount Footage HSI Washington County 330 $18,650 School 630 $35,600 House - 6282 Panama 165 $9,320 Church 135 $7,630 School 330 $18,650 Washington County 555 $31,360 TOTAL $121,210 The total project funding is shown below: Total Project Cost $1,378,830 Residential Assessment Revenue $392,000 OPH Commercial Assessment Revenue $53,470 Stillwater Revenue $121,210 County Turnback Reimbursement General Fund $812,150 The general fund participation as stated in the Comprehensive Street Plan was$576,000 without the cost of storm sewer. Based on this information, the expected cost to the city's general fund taking into account storm sewer and inflation is $721,400. There is a $90,750 difference between the expected burden on the city's general fund and what this report proposes. This difference is due to the addition of Paris Avenue/Beach Road reconstruction. A portion of this difference will be paid by the county through the turnback agreement. 10 PROJECT SCHEDULE Accept Feasibility Report/Schedule February 25, 1997 Neighborhood Meetings Neighborhood Meeting Early March 1997 Public Hearing/Order Plans March 25, 1997 and Specifications Approve Plans and Specifications May 13, 1997 Open Bids June 6, 1997 Award project June 10, 1997 Construction Begins June 17, 1997 Substantial Construction Completed September 5, 1997 Final Project Completion October 10, 1997 Assessment Hearing October 1997 11 • NEW CONCRETE CL CURB & GUTTER Voriob►e Variable Remove Existing Bituminous Curb 49-, • 0.02/ft. 0.02'/ n aTbwr �� 1�2"Type 41 Bituminous Wear Course ,.
