HomeMy WebLinkAbout2018-05-22; City Council; ; Approve plans and specifications and authorize the city clerk to advertise for bids for the 2018 Pavement Overlay Project No. 6001-18OLcalming measures such as narrowing travel lanes and adding pavement legends that provide
guidance to the drivers and bicyclists. As part of this Project, staff is proposing striping changes
along La Costa Avenue that will expand the implementation of a "road diet" between El Camino
Real and Rancho Santa Fe Road. The new striping will expand the road diet to all the segments
along La Costa Avenue that have residential driveway access directly onto La Costa Avenue by
reducing the number of lanes in each direction from two lanes to one lane. This will facilitate
the installation of new and buffered bike lanes, improved safety and reduced vehicular speed
along all segments of La Costa Avenue with residential driveways.
The Mobility Element Implementing Policy 3-P.15, states that" ... The City Council shall have the
sole discretion to approve any such road diet or vehicle traffic calming improvements that
would reduce the vehicle capacity to or below a LOS D,". In support of the proposed changes,
an operational analysis of the striping changes was conducted to evaluate the vehicular levels
of service (LOS) along La Costa Avenue. The LOS is a qualitative assessment of factors such as
traffic volume, roadway geometrics, speed, delay and maneuverability, ranging from LOS A to
LOS F. An LOS A represents free flow traffic, characterized by enhanced mobility and the
absence of traffic congestion. An LOS F indicates overcapacity operation, marked by a loss in
mobility, increased traffic congestion and delays for roadway users. Four intersections and four
representative roadway segments were analyzed and are shown on the following tables.
Intersection Level of Service Analysis
In accordance with the Carlsbad Growth Management Plan and SANTEC/ITE guidelines, the
intersections were analyzed using the Highway Capacity Manual (HCM) methodology. Synchro
10.0 computer software was used with new traffic counts to calculate delay (in seconds). The
intersection LOS is summarized below in Table 1 and shows that the intersection LOS will
remain at LOS C or better after the proposed striping changes.

Mid-block Level of Service Analysis
Traffic counts were collected for the mid-block analysis and utilized to calculate LOS as
summarized in Table 2 below. The analysis shows that the mid-block LOS will remain at A after
the proposed striping changes.

The proposed striping plan for La Costa Avenue was presented to the Traffic Safety Commission
on May 7, 2018 and was unanimously supported by the commissioners.
Implementation of these maintenance activities and the added benefits mentioned above are
examples of the city's organizational values of innovation and stewardship, and community
values of walking, biking, public transportation and connectivity.
Fiscal Analysis
There are sufficient funds available to complete the Project. Funding for the Program consists
of non-jurisdictional fees (generated from trash haulers), Gas Tax Funds, and TransNet-Local
Funds available for drawdown from SAN DAG. Remaining Program funds will be used on future
pavement rehabilitation and resurfacing projects. The available funds and estimated
construction costs for the Project are shown in the following table:

Next Steps
A Request for Bids to construct the Project will be advertised. Responses will be evaluated and
the lowest responsive and responsible bidder will be identified by city staff. Staff will then
return to City Council with a recommendation to award the contract to the identified bidder.
The typical time from authorization to bid to the execution of the construction contract is four
to six months and the construction contract for this Project provides for three months to
construct the Project improvements.
