SUBJECT: DOWNTOWN WATER, SEWER AND MICROSURFACING SUMMER
2010, SPECIFICATION NO. 90976
RECOMMENDATIONS
1. Approve plans and specifications for the Downtown Water, Sewer and Microsurfacing
Summer 2010 Project Specification No. 90976.
2. Authorize staff to advertise for bids and authorize the City Manager to award the contract if
the lowest responsible bid is less than or equal to the Engineer's Estimate of$559,000.
DISCUSSION
The City's Pavement Maintenance Plan (PMP) was adopted by the City Council on April 14,
1998. One element of the PMP is the improvement of the condition of street pavement located in
the downtown area. This particular project includes the microsurfacing of Higuera from Nipomo
to Marsh and Marsh from Higuera to Santa Rosa. In the past, microsurfacing has been used by the
City in maintaining streets, and has been found to be an effective approach in pavement
preservation.
In anticipation of this microsurfacing project, the City's Street Maintenance staff has performed
isolated pavement repairs and crack sealing on the streets included within the scope of this
project. This preparatory work is now complete and will increase the long-term effectiveness of
the microsurfacing application and reduce the construction costs. At the intersections of Marsh
and Broad a sink hole has developed. Several complaints have been received by City staff. This
project will repair the sink hole and replace the existing asphalt surface of other intersections that
are experiencing rutting and asphalt shoving.
This project also includes the installation of nine fire service laterals for downtown buildings.
For several years the Utilities and Public Works Department have worked toward completion of
fire service laterals for the buildings downtown. This has been completed with both waterline
and street paving projects.
Sewer and water improvements that will be included on this project are the replacement of two
sewer mains, one on Garden between Higuera and Marsh and another one on Osos between
Marsh and Pacific. Facilities at both of these locations have been identified by City staff as being
hydraulically overloaded, structurally deficient or containing alignment and grade problems.
Replacing these lines will result in lower operating costs and reduced customer impacts that
would otherwise be associated with emergency repairs. A watermain tie-in and a watermaaiin

replacement will also occur as part of this project. The watermain tie-in is at the intersection of
Marsh and Archer, and will connect a section of main that currently dead ends, and the
replacement is at Garden between Marsh and Higuera. These improvements will provide
increased flow for future developments. Sewer and water improvements are included in this
project because of a need to trench into areas of Marsh receiving microsurfacing and to minimize
future construction related disturbances in the downtown business area.
Construction Impact Mitigation
To minimize the impact of construction to this high pedestrian volume shopping area,staff has
worked with the Downtown Association to determine the least disruptive approach to completing
this project.
The project has been prepared to limit the contractor's work hours to before 11:30 AM or to
require work at night from 11 PM to 7 AM. The contractor will be allowed to work a minimum
of seven and a half hours so that the total duration of this intense type of work activity can be as
short as possible. This approach was recommended by the Downtown Association's Economic
Activity Committee and these provisions have been written into the project specifications.
Community Development has reviewed and approved the City's night work request.
Also discussed with the Downtown Association was the timing of the project. After considering
all factors involved and to minimize the impacts to the downtown merchants and to avoid the
time of year with the greatest likelihood for rain, the project has been scheduled to begin in June
of this year.
Relationship to Short-Term Actions in Fiscal Heath Contingency Plan
The City's Fiscal Heath Contingency Plan was recently activated and as a result all CII' projects are
currently under review for possible deferral or deletion. A report is planned for Council review in
June 2010 that will identify and recommend project deferrals and deletions.
While this review is underway and not yet completed, we recommend going forward with bidding
for this project at this time for the following reasons:
1. This is maintenance-related Enterprise Fund project; and as such,it is unlikely that is would
be a candidate for deletion or deferral. A majority of the project funding comes from
enterprise accounts, which are less likely to be subject to CIP deferrals.
2. This project will complete necessary downtown maintenance work which will prepare the
downtown for future downtown beautification work. This project does not obtain its
funding from identified sources that would fund a future downtown beautification project.
3. Plans and specifications have already been prepared, and the City should capitalize on this
investment.
4. Even if the project became recommended for deletion or deferral,this is only approving the
bid package and authorizing inviting bids: the City could subsequently decide not to award
the bid.

CONCURRENCES
1. The Downtown Association's Economic Activity Committee has recommended that start
of construction be scheduled for June of 2010 and that hours of work be limited as
discussed in this report.
2. The Community Development Department has completed an Initial Study and issued a
Mitigated Negative Declaration
FISCAL IMPACT
Street Reconstruction &Resurfacing Account
There is currently sufficient funding in the Street Reconstruction & Resurfacing Account to
support this request for $251,800. Using this account will allow the Council to reallocate
funding in the Downtown Beautification Project that was intended for microsurfacing of Marsh
Street.
Water Fund
The 2009-11 Financial Plan, Appendix B, pages 3-72 to 3-77 estimates $65,000 in the 2010-11
Project List to support the waterline improvements on Garden Street from Higuera to Marsh and
an additional $30,000 for the Archer Street tie-in at Marsh. Installation of the nine fire laterals for
downtown buildings are not specifically outlined in the Financial Plan. Downtown fire lateral
installations are included in this project, at this time, to ensure that the underground construction
is completed prior to the street microsurfacing.
The water portion of the Engineer's Estimate is $191,750, which includes about 60% ($119,750)
for the waterline improvements on Garden Street and the Archer Street tie-in, and about 40%
($72,000) is estimated for the fire lateral installations. The total fiscal impact for water services
including contingency and construction related services is estimated at $269,850. Sufficient
funding is available in the Water Distribution System Improvements Master Account to support
this request for$269,850.
Sewer Fund
The 2009-11 Financial Plan, Appendix B, pages 3-110 to 3-115 estimates $86,000 in the 2010-11
Project List to support the sewer main replacement on Osos Street from Pacific to Marsh.
Replacement of the sewer main on Garden Street from Higuera to Marsh is identified in the
2012-13 Project List, estimated at $77,000. Staff recommends the replacement of the sewer main
on Garden Street be accelerated to the summer of 2010 to ensure that the underground
construction is completed prior to street microsurfacing and to minimize future construction
related disturbances in the downtown business area.
The sewer portion of the Engineer's Estimate is $171,250, which includes the replacement of
both sewer mains. The total fiscal impact for wastewater services including contingency and
construction related services is estimated at $234,350. Sufficent funding is available in the
Wastewater Collection System Master Account to support this request of$234,350.

Construction Inspection Services
The Downtown Water, Sewer and Microsurfacing project budget does not include funding for
construction management services. Based on the expected workload for current City inspection
staff during the summer months and the suitability of this project for contracted construction
management, staff is recommending adding funds from various accounts totaling $110,000 to
fund construction management and inspection services for this project. The work underway this
summer is the product of the 2007709 and 2009-11 Financial Plans, which funded a very
aggressive Capital Improvement Plan. As the work from these Capital Improvement Plans are
completed, the need for contract construction management should be reduced and as workloads
return to prior year levels, which can be largely manageable by regular staffing resources.

SUBJECT: Downtown Paving Priorities L,.ry mcc-
A question related to the Downtown Microsurfacing project (Item C5) came from Mayor
Romero asking why Chorro Street, between Higuera and Palm, and Carmel Street between
Higuera and Marsh, were not included in this year's Downtown street program. As part of the
2009-11 Financial Plan process, staff identified two projects for inclusion in the downtown
Gateway Paving CIP,microsurfacing of Marsh Street, and reconstruction of Monterey Street.
Two other projects were identified for future years, repaving Pacific Street, from Nipomo to
Broad, and repaving Chorro Street, from Monterey to Higuera. Council gave direction to staff to
make Monterey Street the highest priority project, followed by Marsh Street. Monterey Street is
scheduled to start construction in January of 2011 to coincide with the slow time for the area
businesses. Marsh Street is both an arterial and a downtown street. In the recent update to the
Pavement Management Plan, the Council gave these types of streets the highest priority. The
review that was done by the consultant also confirmed that maintenance of streets in good
condition is money well spent. Chorro Street, for example will need complete replacement
whether we do it this year or next. Staff believes if we do not make spot repairs and get Marsh
Street sealed very soon, it will need complete reconstruction. The microsurfacing proposed is
substantially less disruptive to the downtown than is reconstruction. For this reason, staff put
forward Marsh Street as the highest priority.
The streets identified by the Mayor, which he characterizes as in much worse shape than either
of the streets proposed for seal coat, are anticipated to move forward for reconstruction in
summer of 2011 or 2012 depending upon the needs of the other streets in the arterial system.. For
further questions, please contact Public Works Director Jay Walter.
