O~~i~. "
The city Council at its regular March 2, ,1993 meeting received,
from staff a request to undertake a feasibility report concerning
the reconstruction of two alleys: 1) 12th/13th Ave. North
between 2nd and 3rd streets No., 2) 11th/12th Ave. North between
Mainstreet and 1st Street No. These alleys have been identified
in the past as maintenance problems and have been listed in the
1993 CIP as in need of upgrading. Council authorized staff to do
the study.
In the interim, public information meetings have been held with
the two neighborhoods in question to discuss all improvement
. issues, estimated costs; and assessment policies. An open
discussion was held in both meetings and owners had mostly
positive comments about the proposals. Several residents made
staff aware of, problems or features unique to their frontages
that could have an impact on construction.
Primary Issues to Consider.
. Should the Council accept the feasibility report?
Staff feels it has prepared a complete report and recommends
its acceptance. Two individual reports are attached.
. Should the Council order a public hearing?
Subsequent to the informational meetings, staff feels the
public is aware of the scope and cost of the proposed .
projects and now is the time for formal public discussion.
Staff recommends that Council order ,a public hearing for
May 18, 1993.

FEASIBILITY REPORT
~ CONCRETE ALLEY PAVING
11TH AVE Nj12TH AVE Nj1ST ST Nj400' SOUTH
CITY PROJECT NO. 92-11A
MARCH 30, 1993
Introduction
The 1993-97 Capital Improvement Plan (C.I.P.) includes an alley paving
project for each year of the five year plan. The 1993 plan identified
two alleys that staff determined were necessary to upgrade with
concrete paving due to the high maintenance and drainage problems
associated with them. The city Council reviewed these proposed alley
paving proj ects during their review of the C. I . P., and subsequently
authorized staff to begin the initial analysis of these projects upon
their adoption of the C.I.P.
Backqround
The alley bounded by 11th Ave Nj12th Ave Nj1st st Nj400' south is
presently considered an unimproved alley. Its surface consists of a
1" - 1.5" asphalt layer that has poor drainage character istics . The
combination of the thin asphalt layer and the poor drainage patterns
have resulted in this alley developing many potholes over the years
.. thereby substantially increasing maintenance and other associated
problems.
(
Proposed Desiqn
The proposed alley improvement project provides for the construction
of a concrete pavement surface 12 feet wide and six inches thick in
accordance with the City of Hopkins' improvement policy . New alley
aprons will also be constructed on 1st st N and on 12th Ave N to
better match existing grades on these streets. Driveway aprons will
be paved between the new alley surface and the paved driveways with
similar material as the top surface of the driveway. Gravel will be
placed in driveway openings in all situations other than matching
concrete or asphalt driveways. There will be no sod restoration on
this proj ect. Black dirt and seed will be placed in all disturbed
turf areas along the alley.
The pavement will include a "V" design, slightly depressed in the
middle, to channel water towards the middle of the alley instead of
towards adjacent properties. It is also proposed that the pavement
grades be established to direct the drainage to an existing storm
sewer catch basin located on the south end of the alley.
.

~ Proposed Funding , '
It is proposed that the concrete pavement portion of the proj ect be
assessed in accordance with city policy, 80% against abutting
benef i tted properties and 20% against the Ci ty of Hopkins. It is
further proposed that the storm sewer portion of the project be paid
entirely from the storm sewer utility fund, and also the 20%
assessment against the City of Hopkins.
It has been determined that the fairest method to assess this project
is on a per lot basis. The Hennepin County Library will be assessed
for 6 lots as a direct benefit. u.s. West will be assessed for 6 lots
as an indirect benefit. A summary of the estimated costs and
assessments are provided below. Assessments per lot are shown on the
attached site plan.

Contract Costs $22,035.00
Engineering $ 5,000.00
Total $27,035.00
80% share of Total Project Cost .
per assessment policy $21,628.00
. 18 assessable lots in project
, resulting in a per lot assessment of: $ 1,200.00
Assessment Period 10 years

Recommendation
It is recommended that the city Council accept the City Engineer'S
feasibility report as outlined herein, and order the improvement made
subsequent to holding a public hearing.

It has been determined that the fairest method to assess this project
is on a lineal footage basis. It has been further determined that the
maximum lineal footage assessment will be based on 75 lineal feet due
to the odd shape of a few parcels. A maximum assessment was chosen in
this situation as a means to determine actual benefit of the project.
A summary of the estimated costs and assessments are provided below.
