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.

Analysis of Issues
• Unique Neighborhood Issues
This alley is bounded almost entirely by asphalt paved parking areas serving
adjacent apartment buildings. 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.

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:

Feasibility Report
Recommendations
It is recommended that the City consider completing this alley paving project in conjunction with
anticipated parlcing lot paving in any areas adjacent to the proposed alley. 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.
