This action continues an assessable project for alley upgrading,
Overview,
city Council at its February 4 meeting authorized staff to
undertake a feasibility study concerning the reconstruction of
portions of "T" alleys between Mainstreet/1st Street North and
17th/21st Avenues North, Staff conducted four neighborhood
information meetings to discuss alley reconstruction policy,
costs, and special assessments, The report is completed and now
submitted for Council review and action,

o Report findings and recommendations
The east/west component legs of "T" alleys north of
Mainstreet between 17th/21st Avenues North are deemed
substandard improved alleys, They are bituminous surfaced
roadways in considerable disrepair with numerous patches and
potholes and are plagued with poor drainage patterns. city
vehicles (garbage trucks and snowplows) appear to be
encroaching on private property especially at the "T"
intersections, City vehicles are also tracking across
sidewalk and turf areas near the alley entrances at the
streets and causing various amounts of damage,
The north/south component legs of the "T" alley have been
improved with concrete pavement and are in good condition,
These north/south legs were completed at some time in the
early 1970's and costs were assessed against only those
properties adjacent to the improvement,
The report recommends reconstruction with concrete to a
10-ft, width and with installation of oversized turning radii
to accommodate City vehicles,
The report recommends costs to be assessed in accordance with
city policy (80%-20% split), that the City assume the costs
of the oversized turning radii, and that property owners
north of the project alleys be granted some credit in their
assessments for the past alley special assessments,
o PUblic information
staff conducted four neighborhood meetings to inform owners
of project details. These meetings were poorly attended and
staff will attempt to convene at least one additional meeting
before a public hearing is held,

RE: FEASIBILITY REPORT, CONCRETE ALLEY PAVING
HOPKINS CITY PROJECT 97-02
MSA PROJECT 158-001-10
Dear Mr, Gessele:
As requested, we have reviewed and assisted in the preparation of the engineering feasibility
report for the City of Hopkins 1997 alley paving project. We have reviewed the proposed
improvements and find that they are feasible from an engineering standpoint, 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.
In summary, we believe the improvement is technically feasible and is necessary and
cost-effective, and should proceed in accordance with the attached report.
Sincerely,
MSA, CONSULTING ENGINEERS

FEASIBILITY REPORT
CONCRETE ALLEY PAVING
HOPKINS, MN
PROJECT 97-02
MARCH 4, 1997
Introduction
The 1997-2001 Capital Improvement Plan (C,I.P.) includes alley paving
projects for the first four years of the five-year plan, The 1997 plan
identifies four east/west oriented alleys north of Mainstreet in need
of upgrading with concrete pavement, Improvements are needed due to
the high maintenance costs and drainage problems associated with them,
More.specifically, the alleys are located between 17th and 21st Avenues
North, The City Council reviewed the proposed alley paving projects as
part of the City's annual C.I,P. review process and at its February 4
meeting authorized staff to undertake an analysis of issues and costs
as part of this feasibility report, This report is undertaken without
benefit of property owner petition, so a 4/5 vote of the Council is
required to order the project,
Backoround
The east/west components of "T" alleys bounded by Mainstreet/1st Street
North and 17th/21st Avenues North are presently considered substandard
improved alleys, Pavements consist of 1 to 1 1/2 inch asphalt layers
that are poorly drained, The combination of existing asphalt layers
and poor drainage patterns have resulted in many potholes developing
over the years, thereby sUbstantially increasing maintenance costs.
The north/south components of the "T" alleys were reconstructed with
concrete pavement in the early 1970's and are not in need of an
upgrade,
prooosed DesiCJIl
The proposed alley improvements provide for the construction of a
concrete pavement surface 10 feet wide and 6 inches thick in accordance
with the city's improvement policy. The existing concrete alley aprons
located on 17th-21st Avenues are found to have substandard turning
radii, This factor, as well as their deteriorated condition, warrants
replacement, Driveway aprons adjacent to the alley will be paved
between the new alley edge and paved driveways with materials in kind
found over the existing surface of the private driveway, Aggregate
(granular) materials will be placed in driveway openings where no
existing bituminous or concrete surface pavement exists, No sod
restoration is planned for this improvement project, Topsoil and seed
will be placed on all disturbed turf areas along the alley,
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 in the field to direct drainage to the
streets where existing storm sewer is located, No major grade changes
are planned for areas adjacent to the edges of the reconstructed alley,
Some grade changes will be required from time to time to facilitate
drainage or to comply with driveway design safety standards,
Driveways, whether paved or unpaved, will be regraded to a minimum and
within reason to meet the above mentioned grading standards,
Feasibility Report
Project 97-02
Page Two
CUrrently, the City encroaches on private property at the "T"
confluence with its truck garbage collection and snow-plowing
operations, It is intended where possible to acquire easements over
adjacent properties at these alley intersections for the purpose of
constructing larger turning radii, This will allow for city vehicles
to maneuver alley corners safely,
prooosed Fundina
It is proposed that improvement costs be assessed in accordance with
City policy, 80% 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, Staff has investigated Tax Increment Financing as another
possible funding source, especially for those costs levied against
properties abutting Mainstreet. It appears this cannot be an option
because a TIF district does not exist in the proposed assessment area.
Another source of funding recommended by staff is the City'S refuse
utility. This source should be considered as a means of funding the
additional construction costs associated with the oversized turning
radii required to accommodate City vehicles,
It has been determined that the most equitable method to assess this
project is on a lineal footage basis and that the maximum lineal
assessment for an oversized single family residential property shall be
based on 75 feet, Single family residential lots shall be deemed as
those found in the blocks north of the project alley, commercial
property (all rental property found on the block and all other property
south of the project alley) shall be assessed at its full footage, In
order to provide equitable treatment to these properties north of the
project alley who were previously assessed for alley improvements, it
is proposed that these properties receive a credit, This will lower
their front footage assessment rate and more fairly distribute the
benefit of alley reconstruction. Disregarding inflation over the past
years and concentrating on issues of equity, it is recommended that the
credit be equal to the footage rate paid in the assessments levied in
the early 1970's, A summary of estimated costs and assessments are
provided on the attached sheet.
Reconunendation
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.
