The proposed improvements generally consist of milling and overlaying the pavement surface.
Severe pavement distresses will be removed and replaced. Minor drainage improvements are also
included within the project areas. Watermain gate valve and hydrant bolt replacements are proposed
for these areas.
The project also includes miscellaneous sidewalk and concrete curb and gutter replacement at various
locations throughout the city. Approximately 2,000 feet of trails is proposed to be resurfaced along
the Highway 5 corridor and in the Stone Creek neighborhood.
Also included in this project is expansion of parking in the southeast City Hall parking lot.
A feasibility report will be prepared by the Engineering Dept. staff. The anticipated project savings
will be between $85,000 and $100,000 if feasibility report preparation, design and construction
observation are not outsourced.
Project Area #1: Urban Commercial
This project area consists of 0.71 miles of streets within the western portion of the downtown core:
• West 78 Street between Powers Boulevard and Market Boulevard ranges between 60 and 90
feet wide, with medians. These sections were built in the early 1990's and were sealcoated in
1995.
• Kerber Boulevard south of West 78 Street was constructed in 1972, overlaid in 1996 and
sealcoated in 1997.
• Picha Drive was constructed in 1972 and sealcoated in 1997.
• Target Lane was constructed in 1993.

The Pavement Condition Indices are shown on the map below; a score of 100 represents a new street.
The PCIs range from 19 to 72 within this project area, however staff recommends a mill and overlay
is warranted on the roads with higher PCI's since these segments are collector roads. The streets
segments with the lower PCI's are not collector roads and would benefit from a mill and overlay.
The average PCI for the area is 46 which is within the general guidelines for overlays. Pavements
between 45 and 65 are generally considered needing an overlay. A 3" mill and overlay is anticipated
on W. 78 Street and 2" overlay on the side streets. Included in the project would be new loop
detectors at all the signalized intersections.
Project Area #2: Urban Residential
At the September27, 2010 worksession the portion of Santa Vera drive between Powers Boulevard
and Kerber Boulevard was not included m the proposed project. Following the discussion at the work
session staff evaluated the condition of this street segment and determined that it is also a candidate
for resurfacing. Based on preliminary cost estimates, there is sufficient funds budgeted to include this
area in the project.

There are approximately 1.07 miles of streets within this project area. The street widths range from
23 to 33 feet wide. Santa Vera Drive (Kerber to Saratoga), Chippewa Trail and Chippewa Circle
were constructed in 1987 and sealcoated in 1990 and 1997. Santa Vera Drive (Kerber to Powers) was
constructed in 1995. Saratoga Drive and Circle were constructed in 1978 and sealcoated in 1992 and

1997. The project generally consists of replacing damaged and settled curb, repairing severely
distressed pavement areas, edge milling the streets and placing a paving a 2" overlay. Santa Vera
Drive west of Kerber Boulevard would have a separate assessment since the area is all multi - family
units. Drainage improvements to the intersection of Kerber Boulevard and Santa Vera Drive are also
proposed.

Staff proposes to discuss with the property owners making a ;

with the project.
Project Area #4: Trail Improvements
Along with overlay projects, the City has included trail segments that are in need of repair or
replacement. The Parks Maintenance Department used updated trail pavement condition data and site
investigation to determine the proposed trail segments in the 2011 resurfacing project. Below are
areas that trails are proposed to be replaced. These trail segments show signs of significant
deterioration and should be replaced. The estimate for this work is $75,000.

Project Area #5 South East City Hall Parking Lot Expansion
This project is proposed to maximize the existing
parking lots at City Hall. Currently, the parking lots at
City Hall are full when seniors, the library and the k4 -
City have events planned during the day. Ptillatt 1
City staff has tried to schedule events so parking At° �ik
M
demand is spread out during the day; however these ., • •' �_ „
initiatives have only been somewhat successful. 1 t
l
The proposed parking lot expansion would remove : t t* e
most of the center median from the parking lot, move
the north curb line 3' to the north and reconstruct the ' art
parking lot entrances. The work would allow for 11
additional parking stalls. The cost for the project is
estimated at $70,000 and be funded by the Capital Replacement Fund.
PROJECT FUNDING
Funding for the project is anticipated to come from several sources. Forty percent (40 %) of the street
improvement cost would be assessed back to the benefiting property owners, per the City's
assessment practice. The remaining 60% of the street cost would be a City cost. Each project area
would have its own proposed assessment. The storm sewer and watermain improvements
replacement costs would be funded by the respective utility funds in the annual utility budgets.
The following is the anticipated recommended project budget and funding sources:
Funding Source Amount Budgeted
Assessments/Revolving Assessment Fund $1,200,000
Street Pavement Maintenance Fund $ 300,000
Capital Replacement Fund $70,000
$1,570,000
