Resolution 98 -094, Resolution Ordering Public Hearing, Alley
Reconstruction, Project 98 -14.
This action continues an assessable project for alley upgrading.
Overview
City Council at its December 1 meeting authorized staff to
undertake a feasibility study concerning the reconstruction of

Avenues and the 400 block between 14th /15th Avenues. The report
is completed and now submitted for Council review and action.
Staff will be conducting neighborhood information meetings in

Analysis
•
•
• Report findings and recommendations
The alley in the 300 block between 12th /13th Avenues North
and one in the 400 block between 14th /15th Avenues North are
both deemed to be substandard improved alleys. They are
bituminous surfaced roadways heading more and more into
disrepair and requiring greater levels of maintenance.
Storm runoff from rear residential lots is impaired because
of substandard design. Both alleys are identified in the
1999 CIP for reconstruction with concrete pavement.
The report recommends reconstruction with concrete to a
12 -foot width and with installation of oversized turning
radii at the street intersection to accommodate City
vehicles.
The report recommends costs to be assessed in accordance
with City policy (80 % -20% split), that the City assume its
share of costs to be funded by the storm sewer utility and
that the balance of costs be specially assessed.
• Public information
Staff has scheduled public information meetings to inform
property owners of project details. The meeting date is
January 20.
• Staff recommendations
Staff recommends accepting the feasibility study and
ordering a public hearing for February 2, 1999.

Introduction
FEASIBILITY REPORT
CONCRETE ALLEY PAVING
CITY PROJECT NO. 98 -14
The City of Hopkins' 1999 -2003 Capital Improvement Plan (CIP) includes an alley paving
project for each year within the plan. For 1999, staff determined that the alley between 12th and
13th Avenues from 2nd to 3rd Street North and between 14th and 15th Avenues North of 4th
Street North required upgrades with concrete paving due to the poor drainage and deteriorated
condition of those alleys. 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 1999 -2003 CIP.
Background
The alleys in the 400 block between 14th/15th Avenues North and 300 block between 12th/13th
Avenues North are presently considered improved but substandard. Their surface consists of one
to one and one half inches of bituminous paving with less than adequate drainage characteristics
from the properties to the alleys. The combination of a poor pavement section and inherent
drainage problems has led to the increased rate of deterioration of the alleys. The result is that
levels of maintenance have grown larger.
Proposed Improvements
The proposed alley improvement projects are presented on Exhibit 1 and 2, attached. The
projects provide 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 existing bituminous driveways will be sawcut and restored with bituminous driveway
pavement upon completion of the concrete alley paving. There 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 respective 3rd and
4th Streets North.
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 intersections with City streets.

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,
and that the maximum lineal assessment for an oversized residential property shall be based on
75 feet.

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.

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.
