CR 96-76 Feasibility Report - Alley Reconstruction• • April 11, 1996 Proposed Action. Staff recommends adoption of the following motion: Move that Council adopt Resolution 96-40, Resolution Ordering Public Hearing, Alley Reconstruction, Project 96 -06. This action continues an assessable project for alley improvements. Overview. The City Council at its March 19 meeting authorized MSA Consulting Engineers to prepare a feasibility study concerning the reconstruction of the alley between 1 Street South/2nd Street South and 12 Avenue South/13 Avenue South. The report is complete and now submitted for Council review and action.

The pavement in many of these parking areas is very deteriorated. It would be beneficial to repair these areas in conjunction with the City alley project. Staff is attempting to work with adjacent property owners to determine if there is interest in repairing the adjacent parking lots. In addition to the alley pavement, 1 Street South and r Street South pavements in this area are in very bad condition. The City pavement condition survey shows 1 Street South between 11 Avenue /13 Avenue rated 13 (scale of 1 - 100, 100 being best possible pavement condition), 2nd Street South is rated a 10 and 29. 2 Street South is being reconstructed as part of the CSAH 3 Reconstruction project in 1997. It won't be much longer and we'll need to reconstruct 1s` Street South. It would be wise to reconstruct this alley prior to replacing 1 Street South. • Public Information A public information meeting is scheduled for 7:00 p.m. on April 24` • Staff will discuss the adjacent parking areas, estimated costs, preliminary assessments, assessment policies, and the alley improvement program • Staff Recommendation Staff recommends accepting the feasibility study and ordering a public hearing for May 21, 1996. • introduction FEASIBILITY REPORT CONCRETE ALLEY PAVING CITY PROJECT NO. 96-06 April 11, 1996 The City of Hopkins' 1996 -2000 Capital Improvement Plan (CIP) includes an alley paving project for each year within the plan. In the 1996 five -year Plan, staff determined that the alley between 12th and 13th Avenues from CSAH 3 to 1st Street required an upgrade with concrete paving due to the poor drainage and deteriorated condition of that alley. The City Council reviewed these proposed alley paving improvements during their review of the CIP, and subsequently authorized staff to begin the initial analysis of the improvement upon their approval of the 1996 -2000 CIP. Background The alley bounded to the south by CSAH 3 and the north by 1st Street (between 12th and 13th Avenues) is presently considered an unimproved alley. Its surface consists of one to one and one half inches of bituminous surface with less than adequate drainage characteristics. The combination of a poor pavement section and inherent drainage problems has led to the increased rate of deterioration of this alley. The result is that the alley has developed severe cracking and potholes in recent years, increasing maintenance and other associated problems. Proposed Improvements The proposed alley improvement project is presented on Exhibit 1, attached. The project provides for the construction of a concrete pavement surface 12 feet wide and 6 inches thick, in accordance with the City of Hopkins' concrete alley construction standard The improvements proposed under the CSAH 3 project, south of 2nd Street South, will be designed to accommodate the storm drainage requirements of the proposed alley and its entire drainage area. The existing bituminous parking areas will be sawcut and restored with bituminous driveway pavement upon completion of the concrete alley paving. The will be no sod restoration within the Limits of this project. Any turf restoration required by the project will be accomplished with black dirt and seed. The concrete alley paving will consist of an inverted crown section, which is slightly depressed in the center to allow storm runoff within the alley section versus ponding in the adjacent properties. The pavement grade will be established to direct the runoff to the proposed CSAH 3 storm sewer which will be located at the south end of the proposed alley. It is anticipated that all new alley construction will be limited to the existing 14 foot right of way; however, driveway and parking lot restoration will extend up to two feet beyond the limits of the existing public right of way. The construction will also require the replacement of the concrete apron at the north end of the alley. with its intersection with 1st Street.

NO.3 PROPOSED ALLEY IMPROVEMENTS ASSESSMENT BOUNDARY 0 1 00 Page Three April 11, 1996 Feasibility Report Proposed Funding It is proposed that the concrete pavement project be assessed in accordance with the City of Hopkins' current assessment policy, wherein 80% of the cost is assessed to abutting properties and 20% is funded as a City cost. It is further proposed that the City's portion of the costs 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 linear footage basis. A summary of the estimated costs and a preliminary assessment calculation are provided below: Proieet Costs Alley Construction Costs $30,167 Engineering and Administration $ 5,300 Total Project Costs $35,467 Proposed Funding 80% of Total project cost per $28,373 City policy Assessable linear footage 914.81f Proposed Assessment Rate $31.02/foot Assessment Period 10 years Interest Rate 8.0% Assesjable Properties The following table presents properties within the limits of this project are proposed to be assessed according to the preliminary calculations presented above: • C ? 01 01 t V d CD O C - � � a01* ▪ eta r c1 t Ya CO C 0) 0) QI 0000 O 00 b 00 V1h 40 , 1 1` I` r V1 -.

This would allow construction to occur concurrently and reduce the possibility of damage to the new alley by construction traffic in the near future. The 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. Addended to the end of this report is a summary of the estimated construction costs and a preliminary project schedule for the City Council's consideration.
