Recommended Action Adopt a Resolution approving the modification of the striping plans for t he Vista/Carlsbad Interceptor Relief Sewer on Avenida Encinas, Project No. 3949. Executive Summary The Vista/Carlsbad (V /C) Interceptor Relief Sewer on Avenida Encinas, Project No. 3949 (Project}, between Cannon Road and approximately 2,000 feet south of Palomar Airport Road, is currently under construction. When the underground construction of the· Project is complete, the entire roadway will be resurfaced. Th is results in an opportunity to stripe this portion of Avenida Encinas with buffered bicycle lanes in each direction. Discussion Avenida Encinas is class ified as a Neighborhood Connector Street in the City of Carlsbad Mobility Element. The portion of Avenida Encinas between Palomar Ai rport Road and Cannon Road has a roadway width between 50 and 64 feet and is currently striped with two vehicle lanes in each direction w ith no bicycle lanes. It carries between 6,000 and 9,500 vehicles per day. Surrounding land uses include light industrial, professional offices and restaurants. The posted speed limit on this portion of the roadway is 40 miles per hour. The Project will provide much needed bicycle connectivity between the restaurants and businesses along Avenida Encinas and nearby beaches. Approving the modifications of the striping plans for the Project directly advances the following values identified in the Carlsbad Community Vision: • Small town feel, beach community character and connect edness • Access to recreation and active, healthy lifestyles • Walking, biking, public transportation and connectivity • Neighborhood revitalization, community design and livability • Sustainability December 12, 2017 Item #4 Page 1 of 5 Per the Mobility Element, Avenida Encinas, as a Neighborhood Connector Street, is intended to "connect people to different neighborhoods and land uses of the city" and to be "designed to safely move all modes of travel while enhancing mobility for pedestrians and bicyclists." Staff is proposing to utilize the construction of the Project as an opportunity to enhance bicycle mobility by striping Avenida Encinas with a buffered bicycle lane in each direction. This proposed striping would reduce the number of vehicular travel lanes from two to one in each direction to accommodate the proposed buffered bicycle lanes. In support of this proposal, an operational analysis of the striping changes was conducted to evaluate the vehicular levels of service (LOS) on Avenida Encinas. Level of service is a qualitative assessment of factors such as traffic volume, roadway geometrics, speed, delay and maneuverability, ranging from LOS A to LOS F. LOS A represents free flow traffic, characterized by enhanced mobility and the absence of traffic congestion. LOS F indicates overcapacity operation, marked by a loss in mobility, increased traffic congestion and delays for roadway users. Three locations were analyzed: (1) intersection LOS at Cannon Road/Avenida Encinas; (2) mid-block LOS south of Cannon Road; and (3) mid-block LOS north of Palomar Airport Road. Intersection Level of Service Analysis Since the proposed striping changes would reduce the number of vehicular travel lanes on Avenida Encinas in each direction from two to one, the westbound left turn on Cannon Road at Avenida Encinas would need to be modified from the two existing left turn lanes to one proposed lane. In accordance with the Carlsbad Growth Management Plan and SANTEC/ITE guidelines, the intersection was analyzed using the Highway Capacity Manual (HCM) methodology. Synchro 9.0 computer software was used with recent traffic counts to calculate delay (in seconds). The intersection LOS is summarized below in Table 1 and shows that the intersection LOS at Cannon Road and Avenida Encinas will remain at LOS C or better after the proposed striping changes. Intersection: Cannon Road & Avenida Encinas Existing AM Peak Hour PM Peak Hour Delay LOS Delay LOS (sec) (sec) 15.2 B 22.2 C Mid-block Level of Service Analysis Proposed AM Peak Hour PM Peak Hour Delay LOS Delay LOS (sec) (sec) 17.7 B 22.5 C Traffic counts were collected for the mid-block analysis and utilized to calculate LOS for two locations. The mid-block LOS is summarized below in Table 2 and shows that the mid-block LOS on Avenida Encinas will remain at LOS B after the proposed striping changes. December 12, 2017 Item #4 Page 2 of 5 TABLE 2: Mid-Block Level of Service Summary Existing Proposed Segment: Capacity Volume LOS Capacity Volume LOS (veh/day) (veh/day) (veh/day) (veh/day) South of Cannon Road 30,000 5,307 A 15,000 5.307 B North of Palomar Airport Road 30,000 6,664 A 15,000 6,664 B As noted above, the implementation of the striping modifications will not reduce the vehicle capacity to or below LOS D and therefore staff would be able to proceed with the implementation of the striping modifications in conjunction with the previously approved and ongoing construction of the Project. The proposed striping plan for Avenida Encinas was presented to the Traffic Safety Commission on Nov. 6, 2017 and was unanimously supported by the commissioners. Staff is requesting that Council approve these plans pursuant to California Government Code Section 830.6. Fiscal Analysis There are sufficient funds available to complete the Project. The Project has been previously approved by City Council and is currently under construction. The striping modifications as presented will incur no additional costs to the city since restriping of Avenida Encinas has already been included in the Project budget. The modification to the plans have been made and are on file with Public Works staff. Next Steps After City Council approval of the striping changes, the restriping of Avenida Encinas will commence as part of the Project. Environmental Evaluation (CEQA) A Mitigated Negative Declaration (MND) and Mitigation Monitoring and Reporting Program (MMRP) were prepared for the Agua Hedionda Sewer Lift Station, Force Main and Gravity Sewer Replacement Project PDP 00-02/SP 144/RP 10-26/CDP 10-17 /HDP 10-05/SUP 10- 02/HMP 10-03. The MND was adopted by the City Council on Dec. 6, 2011, in compliance with the California Environmental Quality Act (CEQA) Guidelines Section 15074. The striping changes are within the scope of the MND and no further environmental review is necessary under CEQA Guidelines 15162.
