Oak Park Heights - 1994 Street Resurfacing Program 2
Scope
This project provides for the resurfacing/reconstruction of 3.2 miles of residential streets
in the southwest portion of the City (see Figure No. 1). The proposed construction
includes new concrete curb and gutter, street resurfacing, street reconstruction, and
storm sewer improvements. Details are shown on Figures 2 through 4 at the back of this
report.
This project is the result of the 1993 Comprehensive Street Report which examined the
surface condition and subsurface strength of each street in the project. The surface
evaluation determined the Pavement Condition Index (PCI) which ranks each street
based on its condition. The subsurface strength evaluation determines a recommended
structural improvements for a given axle loading based on a load applied to the existing
street.
The 1993 Comprehensive Street Report addressed the needs for rehabilitating the older
streets in the City. This project is the first of five recommended street resurfacing
projects for Oak Park Heights.
All streets included under this project are streets which presently do not have concrete
curb and gutter. New concrete curb and gutter will be installed as part of this project.
The new concrete curb and gutter will improve drainage characteristics and prolong the
life of the newly reconstructed streets. Y f'0w -Y'
Also included in this project are storm sewer improvements to collect drainage and
reduce the amount of drainage carried in the gutter. These improvements consist of
extending existing storm sewers to intersections where no drainage collection presently
exists.
Preparation of this report was authorized by the City Council on November 22, 1993
with Resolution #93- 11 -43.

Feasibility and Recommendation
This project is feasible from an engineering standpoint and is in accordance with the
Comprehensive Street Plan for the City of Oak Park Heights. The project can best be
carried out as one contract. The contract will include 3.2 miles of residential streets and
related utility improvements.
Street Evaluation
Streets recommended for resurfacing and reconstruction are shown on Figure No. 2
located at the back of this report. Appendix A and Figure No. 5, also located at the
back of this report, summarize the results of the earlier Pavement Strength and Surface
Evaluation Studies completed for the Comprehensive Street Plan.
Three items are considered in determining the condition of an existing street:
Street age —2O 1 Y 30cLk >nzox J6 ` 25fV
Structural strength (recommended structural overlay thickness) 1 V4 - n
• Surface Evaluation (PCI Ranking)
In accordance with engineering standards, the recommended life of a street is 20 years,
based on the anticipated life of the materials (aggregate base, bituminous, and concrete)
used to build that street. However, many factors contribute to whether a street will
function adequately beyond or less than a 20 year period. In the case of this project, the
age of each street exceeds 16 years while many of the streets exceed 25 years.
The desired minimum structural strength of a local street is 7 ton while a commercial
collector street is 9 ton. As presented in Appendix A, a majority of the streets evaluated
require area repair or a bituminous overlay to meet the required axle loading. The
recommended improvements are based on the subgrade condition and existing street
section Effective Granular Equivalence (EGE). The desired granular equivalence for
Oak Park Heights - 1994 Street Resurfacing Program 5 1
a residential street is approximate 14 to 17. A noted in Appendix A, many of the
EGE are below 17. In areas where t s below 14, some subgrade correction
work will be necessary to improve the subgrade strength.
The final and most important consideration in evaluating an existing street is the
condition of its existing surface. The Pavement Condition Index (P CI) ranks the
condition of each street surface. Figure No. 5 at the back of this report presents the
PCI ratings for the streets in this project. Table 1 presents general categories to define
PCI Rankings.
Table 1 - General Categories to Define PCI Rankings
PCI

Maintenance
55 -100
Good to Very Good
Routine Crack Seal and Seal Coat
35-55
Fair
Major Repair Patch & Overlay
0 -35
Very Poor
Overall Repair (Reconstruction)
In general, )`CI13 below 35 require removal of the existing bituminous pavement
before constructing a new bituminous surface. The existing aggregate base may also
have to be reconstructed (subgrade correction). P (rI rankings between 35 and 55
require bituminous surface removal or major patching before constructing a bituminous
overlay. PCi raakWgs wPr�S t<• lly do not require bituminous overlays and generally
routine maintenance such as patching, crack sealing, and seal coats are cost effective.
As noted in Appendix A, and on Figure 5, many of the PCI rankings are below 55, while
some of the PCI rankings are below 35.
Based on the PCI rankings for each street included in the project area, and the fact that
new concrete curb and gutter is proposed, total removal of the existing bituminous is
recommended. Some streets will require removal of the existing aggregate base and
subgrade improvements as well.
Oak Park Heights - 1994 Street Resurfacing Program 6
Discussion
Streets
All street resurfacing and reconstruction proposed under this project will be where no
concrete curb and gutter presently exists. New concrete curb and gutter will be placed
as part of the project. To effectively resurface these streets, a number of surface
preparation steps must be taken prior to placement of the new concrete curb and gutter.
Surface preparation includes the removal or milling of the existing bituminous surface.
Subgrade correction (removal and reconstruction of the existing aggregate base and
some subgrade) is required where the existing street section has failed. It is estimated
that 35 to 40 percent of the existing streets will require some subgrade correction work.
Upon completing the concrete curb and gutter placement for each street, a new 3" thick
bituminous surface will be constructed. Included in the paving process is the adjustment
of manholes and gate valves to the finished surface elevation. Finally, all necessary
sodding and restoration is completed to restore the area to its original condition.
Proposed street improvements are shown on Figures 2 and 3 at the back of this report.
Storm Sewer
Included as part of the 1994 Street Resurfacing Program are storm sewer improvements
as shown on the attached Figure No. 4. The storm sewer improvements include
extensions to the existing storm sewer system to improve street drainage and provide
greater inlet capacity. It is recommended the storm sewer be constructed at this time
to to eliminate the need to disturb the street surface in the future and to prolong the
life of the street. It is also recommended that the upstream drainage area from the end
of the storm sewer system be no larger than 5 acres.
As part of the public notice process, the City may want to ask residents to state if they
have sump pumps and where they presently discharge. It is hoped that the storm sewer
extensions can reduce the number of sump pumps discharging to the sanitary sewers.
Oak Park Heights - 1994 Street Resurfacing Program 7
Sanitary Sewer and Water Main
Miscellaneous sanitary sewer and water main repairs and replacements are included as
part of this project. During the design phase, the City should consider televising the
sanitary sewer in the project area to determine if any major repairs are necessary. For
the purposes of this report, we have estimated the amount of water and sewer repairs
typically required for this type of project. Further review of these items will be
completed during the final design for the project.
Driveway Reconstruction
Due to the new concrete curb and gutter construction, driveway and boulevard
restoration is required. Driveway restoration will include reconstructing the lower
portion of the existing driveway to match the new concrete curb and gutter. Any
disturbed portion of existing driveways will be reconstructed of the same material to an
equal or better condition.
Easements and Permits
The proposed construction will be completed within existing right -of -way and easements.
In areas where narrow or questionable right -of -ways exist, construction will be limited
to replacing the roadway to its existing width. Therefore, we assume that no additional
right -of -way or easements will be necessary. A permit from, Mn/DOT will be required
for the storm sewer between Oldfield Avenue and Olene Avenue along the T.H. 36
service road.
Oak Park Heights - 1994 Street Resurfacing Program 8
Area to be Included
The area to be included for assessment purposes is listed in Appendix B and shown on
Figure 6, located at the back of this report. Figure 7 presents a detail of the assessment
area near Olinda and Olene Avenues.
Properties in this area must be notified for the project hearings.

Assessments
Assessments are proposed to be levied against the abutting benefited property.
Assessment rates for street resurfacing/reconstructing are proposed to be levied based
on the rate classifications shown below:
Assessment Rate Classifications
Residential Curb (75% of total curb cost)
Commercial/Industrial Curb (75% of total curb cost)
Residential Street (50% of total street costs)
Commercial/Industrial Street (50 % of total street costs)
Assessment rates will be determined based on the actual final project costs. Estimated
assessment rates in this report are based on the cost estiamtes in Appendix C.
Residential property will be assessed on a unit (per lot) basis. Multiple residential will
be assessed 0.6 of a residential unit for each multiple unit. Comm ercial/Industrial
property will be assessed on a front foot basis.
The assessable footage is determined in accordance with the Oak Park Heights
Comprebensive Street Plan. After reviewing this project, it was determined to assess
each lot an equal share of the project costs (on a per lot basis). Assessments are
separated as 'concrete curb and gutter" and "street resurfacing" to reflect different City
participation for these two items. It is assumed, for purposes of this report, that storm
sewer extensions and sanitary sewer/water main repairs will not be assessed.
The front foot rates are based on a total assessable footage of 24,870 feet. Assessable
footages for commercial and City property are shown on Figures 6 and 7.
The estimated assessment rates for the 1994 Street Resurfacing Program are presented
in Table 3 below. Assessment rates presented herein will be revised based on final
project costs.

SAMPLE ASSESSMENT CALCULATIONS
The assessment rates for this report are based on the estimated costs contained herein.
The final rates will be determined based on actual final costs. The calculations below
can be followed when determining the final costs.
I. Front Foot Rates for Commercial Property
The front foot rates are determined by dividing the total project costs by the assessable
front footage.
Street: $894,600 - 24,870 feet = $35.97/ft (Total)
Assessment Rate is 50% of total: 0.50 * $35.97 = $17.99/ft.
Concrete Curb:. $459,800 _ 24,870 feet = $18.49 /ft (Total)
Assessment Rate is 75% of total: 0.75 * $18.49 = $13.87/ft.
There are a total of 1,630.41 assessable feet of commercial property. The total proposed
assessments from commercial property (including the City Hall site) is:
Street: 1,630.41 * $17.99 =
Curb: 1,630.41 * $13.87 =
$29,331.07
$22,613.79
Oak Park Heights - 1994 Street Resurfacing Program D -1
H. Per Unit Rates for Residential Property
The per unit assessment rates are determined by dividing the total project costs, less the
portion attributed to commercial property, by the total number of net residential units.
The estimated net total project costs are:
Street: $894,600 - 58,646 (commercial amount) _ $835,954
Curb: $459,800 - 33,146 (commercial amount) _ $426,654
There are a total of 279 net assessable units in the project. Therefore, the proposed
unit rates are:
Street: $835,954 - 279 units = $2,996.25 (Total)
Assessment Rate is 50% of total: 0.50 * $2,996.25 = $1,498.13 per unit
Curb: $420,654 - 279 units = $1,52923 (Total)
Assessment rate is 75% of total: 0.75 * $1,529.23 = $1,146.92 per unit
