PROJECT UPDATE
ACCEPT THE STAFF REPORT ON THE REHABILITATION OF STREETS
IN THE ALMOND GROVE AREA
RECOMMENDATION:
Accept the staff report on the rehabilitation of streets in the Almond Grove Area.
BACKGROUND:
During consideration of the 2010 -16 Capital Improvement Program, the Town Council made an
inquiry with regard to the funding being proposed for an analysis of the condition of streets in
the Almond Grove area. The Council requested that staff include streets outside the Almond
Grove Historic District and also include the Broadway District as well as streets west of the
Almond Grove neighborhood.
In March 2011, staff submitted a report to Council regarding the condition of streets in this
expanded Almond Grove area. The report not only included condition information for each
individual street, but also a range of recommended treatments and associated costs.
The streets in the Almond Grove area are constructed of both concrete and asphalt. There are 10
streets adjacent to the core downtown area with a concrete surface (e.g. Bachman, Tait, Massol,
Broadway) and 21 streets with an asphalt surface in the upper part of the Almond Grove area
(e.g. Alexander, Belmont, and Hernandez.) The conditions of these streets have deteriorated
over the past decades to the point that normal street resurfacing is not an option in order to make
improvements to these concrete streets. These streets are all shown on the Almond Grove
District Street List (see Attachment 1).

SUBJECT: PPW JOB NO. 10 -17 —ALMOND GROVE STREET REHABILITATION
PROJECT UPDATE
ACCEPT THE STAFF REPORT ON THE REHABILITATION OF STREETS
IN THE ALMOND GROVE AREA
BACKGROUND (cont'd.):
In March 2011, staff presented the Town Council with an update on the condition of the Almond
Grove area street infrastructure and a comprehensive program to reconstruct and rehabilitate
these neighborhood streets. The estimated cost to rehabilitate the Almond Grove area street
infrastructure was approximately $19 million. At that time, the majority of streets in the Almond
Grove area were within the Town's Redevelopment Area (RDA) and staff identified funding in
both the Town RDA Budget and regular CIP Budget as a starting point to begin the
reconstruction of these streets.
Minimal street reconstruction work has been performed on the concrete streets in Almond Grove
area over the last several decades for two primary reasons. The first is that concrete streets do
not lend themselves to preventive maintenance treatments compared to asphalt streets. Concrete
streets are typically repaired by removing and replacing entire sections of roadway. Over the
years, this can create a patchwork effect, which can be seen on many of the streets in the area,
particularly those streets that have experienced extensive utility replacement work. The second
reason has been funding constraints. Concrete streets are not good candidates for preventive
maintenance, so the only method by which the streets can be rehabilitated is through complete
reconstruction. This is a relatively expensive proposition when compared to the preventive
maintenance activities associated with asphalt construction. Due to the age and condition of
these concrete streets, nearly all of these streets in the Almond Grove area are now in need of full
reconstruction. Most of the streets in this area are approximately 80 years old and the condition
of these streets has deteriorated over the years, resulting in base failures, uneven surfaces, cracks,
and separation.
In addition to the poor condition of the concrete streets, the curbs, gutters, and sidewalks have
also deteriorated. The curbs, gutters, and sidewalks in the Almond Grove Area were not built to
current concrete construction standards. They are constructed of a thin concrete face, directly on
a gravel and dirt base. The curbs and sidewalks have a high amount of cracking and uplift by tree
root growth. In recent years, the Town has had to allocate a higher than average amount of
resources for patching cracks, grinding surfaces, and replacing entire sections of sidewalk in this
area due to the deteriorating condition.
DISCUSSION:
In early 2012, the State took legislative action to end redevelopment agencies, which was the
primary intended funding source for Almond Grove concrete street reconstruction. Staff has
been working over the past year to address the loss of RDA funding and its impacts on
associated Town projects. In summer 2012, a Successor Agency to the Town's former
Redevelopment Agency was formed as required by state law and various funding options have
been evaluated to address former redevelopment related projects.

PROJECT UPDATE
ACCEPT THE STAFF REPORT ON THE REHABILITATION OF STREETS
IN THE ALMOND GROVE AREA
DISCUSSION (cont'd.):
While the issues regarding the Town's former Redevelopment Agency were being resolved, staff
acted proactively to include asphalt streets in the upper part of Almond Grove area (e.g.
Pennsylvania, Hernandez, Chestnut, Laurel, Madrone, Overlook) that were outside of the Town's
RDA boundaries in the annual street resurfacing project, and half of these streets were resurfaced
in summer 2012. The remaining asphalt streets will be included in the summer 2013 street
resurfacing project. This resurfacing work (cape sea]) is funded by the Town's regular CIP
Budget. The above mentioned streets did not require full reconstruction like the concrete streets
closer to the core downtown area. By the end of summer 2013, a total of 21 asphalt streets in the
Almond Grove area will have been resurfaced at a cost of approximately $900,000. This cape
seal resurfacing approach on the asphalt streets resulted in substantial cost savings in place of
conventional asphalt overlay for the Town.
The reconstruction of the remaining 10 concrete streets in the neighborhood is more complex
because there are many factors that need to be evaluated and considered for this project. The
Almond Grove and Broadway districts are classified as historic areas. According to the Town
Code, the street surfaces in this area should remain of concrete construction to retain the historic
character of the area. The Town Council may make changes to the codes and policies, as
necessary, and it may require Council to reassess the construction materials used on the streets in
these areas.
The cost of construction associated with concrete streets has historically been higher than that of
asphalt streets. The December 2012 cost estimate to reconstruct these streets with concrete is
$13.8 million as opposed to $11.8 million with asphalt, making concrete approximately 17%
more expensive than asphalt.
The multiple phases of construction and neighborhood impacts are other key points that should
be considered. Most houses in the neighborhood have very limited garage facilities and on- street
parking, so convenient access to streets is important to these residents. The construction of a
concrete street will take almost twice as long as an asphalt street. Additionally, during
construction on- street parking and access will be severely limited. In past years the Town has
worked closely with residents and merchants to minimize inconveniences due to construction
projects in and around downtown and will do so in the reconstruction of concrete streets in the
Almond Grove area. There are many details yet to be resolved to ensure the project is
constructed expeditiously and with the least amount of inconvenience to the public.
The long -term maintenance cost for a concrete street will be less than an asphalt street. However,
over time, as new utility service connections for the house remodels /construction are completed,
it will require cutting into the new street section and patching the street afterwards. The patches
will be more visible on concrete streets, as seen today with an assortment of utility trench cuts
and patches in the neighborhood. On asphalt streets such utility trench cuts can be resurfaced and
look similar to the existing asphalt surface.

MAYOR AND TOWN COUNCIL
SUBJECT: PPW JOB NO. 10 -17 —ALMOND GROVE STREET REHABILITATION
PROJECT UPDATE
ACCEPT THE STAFF REPORT ON THE REHABILITATION OF STREETS
IN THE ALMOND GROVE AREA
DISCUSSION (cont'd.):
If funding for the Almond Grove Street Reconstruction project is allocated and the Town
Council approves this as a Capital Improvement Project, staff will hold neighborhood meetings
to discuss various project options and solicit input as to the preference of the neighborhood on
concrete versus an asphalt street and report back to the Town Council.
CONCLUSION:
Staff recommends that the Town Council accept this report and provide input to staff regarding
this project.
ENVIRONMENTAL ASSESSMENT:
This is a project as defined under CEQA, but is Categorically Exempt (Section 15301c). A
Notice of Exemption will not be filed.
FISCAL IMPACT:
The estimated cost to reconstruct concrete streets in the Almond Grove area is approximately
$11M to $14M in today's dollars. As staff prepares the 2013/14- 2017/18 CIP Budget, funding
from a variety of sources may be available to fund some portion of the identified improvements,
even with the State and County taking the previously budgeted Redevelopment funds. The
reconstruction of streets in the Almond Grove area will likely need to be a multi -phase project
according to the funding that may be allocated. Council discussion of and direction on potential
phasing will aid in preparation of Capital Budget alternatives for Council consideration at the
January 22, 2013 Capital Project Priorities and Funding Study Session.
