Agenda Item
1. Proposed Pavement Management Capital Improvement Plan Modifications
Prepared By
Jeannine Clancy, Director of Public Works
Jeff Oliver, City Engineer
Summary
As requested, Public Works staff has prepared an alternative Capital Improvement Plan (CIP)
for the Pavement Management Program (PMP). The current CIP includes completion of the
reconstruction phase of the PMP in 2014, with the reconstruction of non-standard streets in
the lakeview Heights area. The proposed modified PMP extends the reconstruction schedule
to 2019, with the lakeview Heights area the last to be completed.
This memorandum will outline the construction costs used for the development of the existing
and proposed CIPs and describe the proposed modifications to the plan.
Construction Cost Calculations
The street reconstruction costs utilized for the existing and proposed CIPs have been
updated to more accurately reflect the actual costs incurred by the City in recent years.
These costs were calculated for the street reconstruction portion of the proiect on/v, using the
PMP projects since 2005 to obtain a cost per mile of street reconstruction. Therefore, the
costs reflect projects with difficult subgrade conditions that require significant correction
costs, and areas where minimum subgrade corrections were required.
In addition to the construction costs, the calculated project costs include all indirect costs,
including an estimated 24 percent for preliminary and final design, construction observation,
surveying and project management. An additional 6 percent of the construction costs were
included for administrative costs. Therefore, the total indirect costs are an estimated 30
percent of the construction costs.
Based upon the above discussion, the baseline project cost to be used for the 2010 PMP is
$1.4 million per mile. These costs were adjusted annually for inflation at a rate of 4 percent.
The cost calculations are for local streets only and therefore do not include Municipal State
Aid (MSA) roadways. Because MSA streets require a higher axle loading design as required
by State Aid Rules, resulting in additional subgrade correction and pavement thicknesses,
and MSA streets include minimum street widths that may exceed City practice, a separate
project cost calculation is used for these streets. The CIP for Golden Valley's remaining
substandard MSA routes is currently in development and is not included at this time.
Funding for sanitary sewer, watermain and storm sewer construction associated with these
projects is from sources separate from street reconstruction. Therefore, these costs are not
included in the estimated project costs used in the CIP development.
Existinq Pavement Manaqement Proqram CIP
The existing PMP program formally began in the mid-1990s, and was modified by the City
Council shortly thereafter. The program included two construction seasons where
approximately 15 miles of roadway were reconstructed in 2000 and 2001, followed by
reconstruction of approximately 8 miles of streets in the Brookview area in 2003 and 2004.
Subsequent projects included approximately 3 to 4 miles of street reconstruction annually
through the completion ofthe program in 2014. This CIP has resulted in approximately 80
percent of the City's local streets being rehabilitated to City standards. The current CIP is
illustrated on the attached Pavement Management Capital Improvement Plan.
While illustrated on the attached exhibit, the cost calculations do not include significant MSA
reconstruction projects such as Zane Avenue and Lindsay Street, Harold Avenue or Duluth
Street.
Based upon the adjusted project costs discussed above and the existing CIP, the estimated
street reconstruction costs are as follows:
Project Cost
Year Miles Cost/Mile (street only)
2010 2.6 $1,400,000 $3,640,000
2011 4.4 $1,456,000 $6,406,000
2012 3.2 $1,514,200 $4,846,000
2013 3.1 $1,574,800 $4,882,000
2014 3.1 $1,637,800 $5,077,000
Proposed Capital Improvement Plan
The modified CIP, as shown on the attached Pavement Management Capital Improvement
Plan: PROPOSED, extends the reconstruction phase of the PMP to a 2019 completion. This
alternate plan was developed with a target budget between $2 million and $3.5 million per
year. This target budget has been achieved in all project years except 2010 and 2019.
Highlights of this plan include:
. Maintains the entire proposed 2010 PMP, which is currently in the preliminary design
phase, with resident open houses scheduled for May, and the public hearing
scheduled for August 2009.
. Divides the current plan for 2011 into two separate projects in 2011 and 2012.
. Divides the proposed 2012/2013 PMP, located north and south of 23rd Avenue North
and west of Winnetka Avenue, into five separate years.
. Maintains the Lakeview Heights area as a single project at the completion of the
reconstruction portion of the CIP in 2019.
The Lakeview Heights neighborhood is maintained as a single project due to the storm water
drainage patterns combined with a layout that makes the neighborhood difficult to split
without construction impacts for the entire neighborhood during a two-year construction
project.
While illustrated on the attached exhibit, the cost calculations do not include significant MSA
reconstruction projects such as Zane Avenue and Lindsay Street, Harold Avenue or Duluth
Street.
The estimated street reconstruction costs of the modified CIP are as follows.
Project Cost
Year Miles Cost/Mile (street only)
2010 2.6 $1,400,000 $3,640,000
2011 1.6 $1,456,000 $2,330,000
2012 1.2 $1,514,200 $1,817,000
2013 1.5 $1,574,800 $2,362,000
2014 1.8 $1,637,800 $2,948,000
2015 1.2 $1,703,300 $2,044,000
2016 1.3 $1,771,400 $2,303,000
2017 1.1 $1,842,300 $2,027,000
2018 1.0 $1,916,000 $1,916,000
2019 3.1 $1,992,600 $6,177,000
The PMP CIP should be reviewed annually to determine if future economic and debt
conditions warrant modifying the program to complete the reconstruction phase as early as
possible.
Pavement Overlavs
The Pavement Management Policy includes maintenance and rehabilitation of the streets in
order to maximize their functional lifespan, including sealcoating and pavement overlays. The
sealcoating program has a long history in Golden Valley, with this maintenance and
preservation activity limited to streets that are constructed to City standards.
In accordance with the Pavement Management Policy, staff has begun implementing
pavement overlays in recent years. The emphasis of the recent overlay activities has been on
high volume roadways such as MSA streets and trunk highway frontage roads, with some
overlays performed on local streets that were reconstructed approximately 25 years ago and
that exhibited a need for this treatment method.
Current funding sources for pavement overlays in Golden Valley include MSA funds and local
street improvement funds. In addition, Minnesota Statutes, Chapter 429, allows cities to levy
special assessments for public improvements, including pavement overlays. In the past,
special assessments have been utilized for street reconstruction, but not for pavement
overlays.
Public Works staff recently completed a survey of 13 cities to determine the prevalence of
special assessments as a funding source for pavement overlays. As expected, the use of
assessments, and the methods of assessment varied widely among these communities. One
of the cities has a very limited program, with overlays on a block-by-block basis that are
performed adjacent to street reconstruction projects and funded by the city.
Of the remaining 12 cities, 6 utilize special assessments and 6 fully fund the overlays. The
assessment rates ranged from 33 percent of the project costs to 100 percent of the costs. In
addition, there was variability in the method of assessments (front foot or per unit charges)
and rates assessed to high traffic generating uses such as commercial and industrial land
uses.
The Golden Valley street system was re-evaluated in the fall of 2008 for pavement condition.
Staff is in the process of evaluating options for a long-term pavement overlay plan based
upon these pavement ratings, traffic conditions and financing. The results of this analysis will
be forwarded to the City Council when completed.
Impact on Operatinq Funds
The extension of the PMP CIP will have an impact on the City's streets maintenance budget
funded by the General Fund. Because many of the streets are beyond their useful life,
significant patching will need to be done to maintain a safe driving surface. Staff is in the
process of developing cost estimates for additional patching and repair of streets, which may
be included in the City's Street Department's 2010 budget request if this CIP revision is
adopted.
