. Feasibility report findings and recommendations:
The recommended project provides for the construction of a concrete pavement surface 10 to 18
feet wide and 6 inches thick, in accordance with the City of Hopkins' concrete alley construction
standard. The additional width, up to 18 feet, is needed for the east-west alley segment for City
maintenance and refuse pickup purposes. Existing grade and erosion issues are proposed to be
improved by using a new alley profile and 8 inch integral curb in some areas.
The project is necessary to correct maintenance problems caused by inadequate alley surfacing.
Maintenance problems include high maintenance costs for adding gravel, maintaining a gravel
surface, controlling erosion, and other problems associated with overall poor drainage. The
project is feasible, cost effective, necessary, 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 and order the
improvement made, subsequent to holding a public hearing.
. Project 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. Additional drainage
improvements at Hilltop Park at the north end of the alley dead end would also be paid from the
storm sewer utility fund.
Because there are such unique circumstances surrounding this project site, including the unusual
"L" shaped functional nature of this alley, staff feels that the fairest method to assess this project
is on a per unit basis rather than on an abutting linear footage basis as is usually done with alley
assessments, and that each abutting property be assessed the same as they all have equal
eligibility to use the alleyway. This assessment method is consistent with past assessments for
Hopkins alley projects by assessing each abutting property in the same manner even though
every property doesn't currently use the alleyway for their primary driveway access. As
mentioned above, each property has the same eligibility to use the alley and the potential for
future redevelopment or changes to each of the properties means each property should be
assessed in the same manner. The City staff is also of the opinion that the computation for the
costs eligible for assessment should be based off a 10 foot wide alley section for the entire length
of the functional alleyway because the additional 8 foot width for the east west portion is needed
to benefit the City for maintenance and refuse pickup purposes. Preliminary estimated amounts
for assessments computed in accordance with the per unit 10 foot alley method outlined above
have indicated assessments in the range of approximately $1,993 per unit. This amount is
. consistent with assessment amounts for other recent alley projects in the City of Hopkins. The
costs associated with this additional width would come out of the PIR Fund.

Introduction
For a number of years the City of Hopkins has identified concrete alley paving projects to
improve the function. drainage, and maintenance of many problematic City alleyways. The
2000-2004 Capital Improvement Plan (erp) first identified an alley paving project for the alley
west of 191h Avenue North, north of 3rd Street North for the year 2002. Subsequent Capital
Improvement Plans (2001-2005 and 2002-2006) have continued the identification of this alley
for reconstruction in 2002 due to its designation as poor on the alley condition survey. On
November 8, 2000, the Hopkins City Council adopted a resolution ordering the preparation of a
feasibility report for this project. At the time, consideration was being made to possibly
construct the project in 2001 rather than 2002. It was determined that thc alley required
upgrades with concrete paving due to lhe poor drainage and deteriorated condition of the alley.
When one of the properties on the alley decided to rcmove and replace their garage in 2001. it
was determined by staff that reconstruction of the alley sllould not take place until 2002 as
. originally planned in the elr.
f
i
I
Background
. The alley under consideration is the only roachvay acc~ss to two properties located between
Hilltop Park and 19th A venue North in the #300 block. The alley connects with a short improved
section of 3rd Street North and thence to 19 Avenue N0l1h. The existing alley is constructed with
a gravel/ bituminous millings surface that is considerably deteriorated. Maintenance is an on-
going issue because of an increasing need for filling in and patching various areas due to erosion.
sluffing. and rutting. Issues of drainage arise in attempting to channel storm runoff into Jrd Street
or to an established low area adjacent to Hilltop Parl..;:. There are also issues of vehicle maneuvers
for trash collection and snow removal. The combination of a poor surface section and inherent
drainage problems has led to the increased rate 0 r deterioration of the alley. The result is that
levels of maintenance have grown larger.
Proposed Improvements
The proposed alley improvement projects are presented on the attached plan sheet. The project
provides for the construction of a concrete pavement surface 10 to ] R feet \vide and 6 inches
thick, in accordance with the City of Hopkins' concrete alley construction standard. The
additional width. up to 18 feet. is needed lor the cast-west alley segment for City maintenance
and refuse pickup purposes. Existing grade and erosion issues are proposed to be improved by
using a new alley profile and 8 inch integral curb in some areas.
. The existing bituminous driveways will be sawcut and restored with bituminous driveway
pavement upon completion or the concrete alley paving. Existing gravel driveways will be
replaced with similar gravel materials of equal or greater depth than existed previous to the alley
reconstruction. 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. An erosion
control blanket will be used to help establish vegetation on existing steep slopes while preventing
eroSIOn.
The concrete alley paving will consist of an inverted crown section. which is slightly depressed
in the center to allow storm runoffv,iithin the alley section versus ponding in the adjacent
properties. The pavement gradc will be established to direct the runoff to the respective Hilltop
Park and 19th Avenue North.
A utility pole, located within the north-south right of way is proposed to be relocated in
conjunction with the project to allow for better access to driveways off the alley and remove a
potential obstruction.
It is anticipated that all new alley construction will be limited Lo the existing 12 foot north-south
and 60 foot east-west respective right-of-ways: however, driveway restoration will extend up to
five feet beyond the limits of the existing public right or way where it is only 12 feet wide
(north-south). Temporary construction easements may be needed to help better facilitate
construction activities. The 60 foot cast-west right-of-way segment is an extension of the 3rJ
. Street North right-of-way but functions as and will remain an alley segment due to grade and
right-of-way issues. As mentioned above. an 18 foot alley segment will be installed in this
section for City maintenance and refuse collection purposes. The construction will also require a
concrete apron at the intersecti on "vi th I 91h A venue North.

Proposed Fundin!?;
It is proposed that the concrete pavement project be assessed in accordance with the City of
Hopkins' current assessment policy, wherein RO% ofthe 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 eosts be
paid entirely from the storm sewer utility fund. in accordance with City policy. Additional
drainage improvements at IIiJJtop Park at the north end ofthc alley dead end would also be paid
from the storm sewer utility fund.
Because there are such unique circumstances surrounding this project site, including the unusual
"L" shaped functional nature ofthis alley, stall feels that the fairest method to assess this project
is on a per unit basis rather than on an abutting linear rootage basis as is usually clone with alley
assessments, and that each abutting propelty be assessed the same as they all have equal
eligibility to use the alleyway. This assessment method is cnnsistent with past assessments for
Hopkins alley projects by assessing each abutting property in the same manner even though
every propclty doesn't currently use the alleyway 1'01' their primary driveway access. As
mentioned above, each property has the same eligibility to use the alley and the potential for
. future redevelopment or changes to eaell or the properties means each propelty should be
assessed in the same manner. The City stan is also of the opinion that the computation for the
costs eligible for assessment should be based off a 10 foot wide alley section for the entire length
of the functional alleyway because the additional 8 foot width for the east west portion is needed
to benefit the City for maintenance and refuse pickup purposes. Preliminary estimated amounts
. for assessments computed in accordance with the per unit 10 root alley method outlined above
have indicated assessments in the range of approximately $1.993 per unit. This amount is
consistent with assessment amounts for other recent alley proj ects in the City of Hopkins. The
costs associated with this additional width would come out of the PIR Fund.
