Alley Improvement Project 97 -16
Proposed Action.
Staff recommends adoption of the following motion: Move that Council Adopt Resolution 98 -15.
Resolution Ordering Public Hearing A lle y Reconstr Project 97 -16.
This action continues an assessable project for alley upgrading.
Overview.
City Council at its December 2, 1997 meeting authorized staff to undertake a feasibility study
concerning reconstruction of the alley between the Hopkins Arts Center and the US West Central
Office building. Staff had hopes of negotiating for an easement from US West in return for
forgiveness on a potential alley assessment. The easement would allow the City to create a potential of
eight parallel parking stalls adjacent to the US West building. Negotiations have stalled and staff now
presents the feasibility report in order to follow prescribed procedures for an assessable project.
Primary Issues to Consider.
• Report findings and recommendations
Staff will discuss the details of the report in summary form.
Council orders public hearing
Public hearing
Approve plans
Bid opening
Award bid
Begin construction
• Parking issue
Should US West refuse to negotiate an easement or consent to a reasonable sale price of portions
of its property, staff is recommending the City forego any thoughts of reserve parking on the north
side of the alley.
• Recommendation
Staff recommends ordering a public hearing for April 7, 1998.

Feasibility Report
Concrete Alley Paving
Hopkins, Minnesota
Project 97 -16
March 17, 1998
Introduction.
The 1998 -2002 Capital Improvement Plan (C.I.P.) includes alley paving projects for the first four
years of the five -year plan. The 1998 plan identifies an alley north of Mainstreet between the
Arts Center and the US West building in need of upgrading with concrete pavement. More
specifically, the alley connects 1 lth and 12th Avenues North immediately to the rear of the Arts
Center. Improvements are needed due to high maintenance costs and drainage problems
associated with them. Placement of this project in the current C.I.P. is taken as a directive in
preparing an engineer's report. This report is undertaken without benefit of property owner
petition, therefore a 4/5 Council vote is required to order the project.
Background.
The alley between 1 lth and 12th Avenues North, bounded by the Hopkins Arts Center on the
south and the US West Central Office building on the north, is considered a substandard
improved alley. The pavement consists of 1 to 1 '/2 inch asphalt layers. Grades are minimal and
the pavement is poorly drained. The combination of asphalt layers and poor drainage patterns
have resulted in many potholes. This in turn points to increasing maintenance costs.
Proposed Design.
The proposed alley improvements provide for the construction of a concrete pavement surface 12
feet wide and 6 inches thick in accordance with the City's improvement policy. Restoration of
pavements between the concrete alley edges and the Arts Center on the south and US West's
concrete curb on the north will be with bituminous material. Turf restoration is anticipated to be
minimal. No sod is planned for this project.
The pavement section will include a "V" design, slightly depressed in the middle to channel
water away from adjacent properties. Pavement grades will be established to direct drainage to
catch basins that are part of a 130 -foot storm sewer system proposed for this project. Some grade
changes between the concrete pavement and the construction limits will be required from time to
time to facilitate drainage or to comply with driveway design safety standards.
The engineer recommends that measures be taken to connect two US West facilities to the
proposed alley storm sewer: a sump pump discharge that currently pours out over the alley
surface and a roof scupper and downspout that drain out over the current alley pavement. In both
instances, the drainage is prone to freezing and ice buildup.
The engineer recommends reversing flow of traffic through the alley to that of east to west and
that the parking lot adjacent to the Arts Center be reconfigured and expanded to accommodate
this change. The engineer also perceives the added advantage of creating potential parking
facilities along the north edge of the alley by reversing the traffic flow.
ronosed Funding
It is proposed that improvement costs be assessed in accordance with City policy, 80% of alley
paving costs assessed against abutting benefited properties and 20% paid by the City. The City's
share of alley improvement costs is paid entirely from storm sewer utility funds in accordance
with the current policy. It has been determined that the most equitable method to assess this
project is on a lineal footage basis. A summary of estimated costs and assessments are provided
on the attached sheet.
Recommendation.
The project is necessary to correct maintenance problems caused by inadequate alley paving.
Maintenance problems include high maintenance costs for patching and other problems
associated with poor drainage. The project is cost effective and it is part of the City's annual
alley paving program. The City plans for necessary capital improvements annually to coordinate
other work and ensure that necessary improvements are provided in a timely and cost - effective
manner. This concrete alley paving project is technically feasible from an engineering standpoint
and it is recommended that the City Council accept the engineer's report as outlined herein, and
order the improvement made, subsequent to holding a public hearing.
