CR 96-44 Feasibility Report 96-05• • February 28, 1996 Proposed Action. Staff recommends adoption of the following motion: Move that Council adopt Resolution 96 -21 Resolution Ordering Public Hearing, Alley Reconstruction. Proiect 96 -05. This action continues an assessable project for alley upgrading. Overview. The City Council at its February 20 meeting authorized staff to undertake a feasibility study concerning the reconstruction of the "T" alley between Mainstreet /2nd Street South and 6th /7th Avenues South. The report is completed and now submitted for Council review and action. Primary Issues to Consider. o Unique neighborhood issues An issue to address is that of right -of -way. City trucks in carrying out plowing activities or trash collection are encroaching on private property at the northwest corner of the "T" configuration. Easements will need to be acquired. o Public information Staff anticipates organizing public information meetings with property owners the latter part of March. Improvement issues, estimated costs and assessment policies will be discussed. o Staff recommendation Staff recommends accepting the feasibility study and ordering a public hearing for April 2, 1996 SuDnortina Information. o Feasibility report o Resolution 96 -21 es Gessele Engineering Superintendent ACCEPT FEASIBILITY REPORT ORDER PUBLIC BEARING ALLEY RECONSTRUCTION PROJECT 96 -05 Council Report 96 -44 • Introduction The 1996 -2000 Capital Improvement Plan (C.I.P.) includes an alley - paving project for each year of the five -year plan. The 1996 plan identified two alleys that staff determined were necessary to upgrade with concrete paving due to the high maintenance and drainage problems associated with them. The City Council reviewed these proposed alley - paving projects during their review of the C.I.P., and subsequently authorized staff to begin the initial analysis of these projects upon their adoption of the C.I.P. Background FEASIBILITY REPORT CONCRETE ALLEY PAVING CITY PROJECT NO.96 -05 March 6, 1996 The "t" alley bounded by Mainstreet/2nd Street South and 6th/7th Avenues South is presently considered an unimproved alley. Its surface consists of a 1 to 1.5 inch asphalt layer that has poor drainage characteristics. The combination of the thin asphalt layer and the poor drainage patterns have resulted in this alley developing may potholes over the years, thereby substantially increasing maintenance and other associated problems. Proposed Design The proposed alley improvement project provides for the construction of a concrete pavement surface 12 feet wide and 6 inches thick in accordance with the City of Hopkins' improvement policy. The existing concrete alley aprons located on 7th Avenue South and 6th Avenue South are in good condition and will not need to be replaced. Driveway aprons will be paved between the new alley surface and the paved driveways with similar material at the top surface of the driveway. Gravel will be placed in driveway openings in all situations other than matching concrete or asphalt driveways. There will be no sod restoration on this project. Black dirt and seed will be placed in all disturbed turf areas along the alley. The pavement will include a "V" design, slightly depressed in the middle, to channel water toward the middle of the alley instead of toward adjacent properties. It is also proposed that the pavement grades be established to direct the drainage to the existing storm sewer systems located in the current alley and in 7th Avenue South. Currently, the City of Hopkins is encroaching on private property in this alley with its garbage collection and snow - plowing operations (Addr: 53 7th Avenue South). It is intended to acquire an easement over a portion of this lot to allow for city vehicles to maneuver the alley corner safely. This same lot has drainage problems that can be resolved by making alley grade changes. Nevertheless, items for an extra catch basin and 8" PVC storm sewer are included in the preliminary cost estimate as an alternative. The concrete paving will stop short of the parking lot and its driveway lane adjacent to the • Hopkins Village Apartments. The fall in grade from the parking lot to the alley is more than adequate to accommodate proper drainage. Transition from concrete to bituminous will be provided. Proposed Funding • It is proposed that the concrete pavement portion of the project be assessed in accordance with city policy, 80% against abutting benefited properties and 20% against the City of Hopkins. It is further proposed that the City's share of the project be paid entirely from the storm sewer utility fund in accordance with city policy. It has been determined that the fairest method to assess this project is on a lineal footage basis. It has been further determined that the maximum lineal footage assessment for two residential corner lots and one over -sized 150 foot residential lot will be based on 75 lineal feet. A summary of the estimated costs and assessments are provided below. Project Costs Alley Contract Costs $41,311.00 Engineering 500.00 Total $41,811.00 80% share of Total Project Cost per assessment policy $33,448.80 Assessable lineal footage 1265 ft. Lineal Footage Assessment $26.44 Assessment Period 10 years Interest Rate 8.0% Recommendation This concrete alley paving project is technically feasible from an engineering standpoint and it is recommended that the City Council accept the project engineer's feasibility report as outlined herein, and order the improvement made, subsequent to holding a public hearing.
