City Council Agenda Item 9e Page 1 of 5 February 4, 2025 City Council Agenda Item 9e
STAFF REPORT
TO: Honorable Mayor and Councilmembers
FROM: Larry Theis, City Engineer
DATE: February 4, 2025
SUBJECT: Review and Potentially Select a Restriping Alternative for Mountaire Parkway between Marsh Creek Road and Mountaire Circle (south – swimming pool) from Four Lanes to Two Lanes
RECOMMENDATION
Assuming the City Council would like to proceed with a lane reduction on Mountaire Parkway, City Staff recommends the installation of Alternative Alignment #2 – which includes a two way left turn lane (center median), bike lanes, and on-street parking. This alternative provides a balanced apportionment of the roadway – allowing for turning vehicles to exit and queue in a center turn median without backing up through vehicular traffic, adds exclusive bicycle lanes, and maintains existing curbside frontage parking.
BACKGROUND
In May 2022, the City Engineer received a request from a Dana Hills property owner to consider reducing the four-lane section of Mountaire Parkway to two lanes for traffic calming (Back to Agenda)
City Council Agenda Item 9e Page 2 of 5 February 4, 2025 purposes. Staff informed the property owner that the City could consider this request since this segment of roadway was scheduled for resurfacing in 2023, but we requested the Dana Hills homeowner’s association submit an official request on behalf of the neighborhood to ensure there was some consensus among the affected homeowners.
Later in 2022, Staff informed the Dana Hills property owner that the resurfacing project was rescheduled to the summer of 2024 since it required additional time to obtain federal and CCTA funding authorizations. In March 2023, the Dana Hills HOA reinitiated the matter and emailed a survey request to its 503 households. The survey results included 129 responses with 86 generally in favor of the lane reduction and 43 generally opposed. Most of the written feedback was from those opposed but there appeared to be a strong majority of those that responded to be in favor. The HOA Board were supportive at that time.
At its January 11, 2024 HOA Board meeting, the majority of the Board decided they were not in favor of a lane reduction due to comments from members attending the meeting and the lack of feedback from the entire neighborhood with only 20% of the HOA members responding to the survey back in April 2023.
In April 2024, City Staff received a request from other Dana Hills property owners to implement the lane reduction and they were informed of the HOA’s prior decision to not pursue the matter. They were directed to contact the HOA to advocate for the HOA’s official request to the City for the lane reduction on Mountaire Parkway.
This matter was initiated by Councilmember Wan at its last meeting on April 16, 2024, for an update, discussion, and decision to potentially amend the resurfacing project to modify the striping on Mountaire Parkway from four lanes to two lanes.
At its May 7, 2024 meeting, the City Council unanimously agreed to direct City Staff to complete its 2024 Paving Project using traffic paint (instead of typical thermoplastic striping) on the segment of Mountaire Parkway between Marsh Creek Road and Mountaire Circle (south-swimming pool) after pavement resurfacing back to its existing configuration of four lanes. This direction was given to avoid delays and/or potentially jeopardizing the already allocated federal grant funds. The use of traffic paint would also better accommodate the possibility of following up with a restriping project in 2025 to change the four-lane configuration to two lanes with bicycle lanes.
Since the May 7th meeting, City Staff updated the plans to change the type of striping from thermoplastic to traffic paint and then advertised for bids. The project was awarded in July 2024, construction began in September 2024 and was completed in November 2024 – with the aforementioned segment of Mountaire Parkway striped to its pre-project four lane configuration using traffic paint (which is expected to last 3-5 years).
The City Engineer, using the services of its subconsultant traffic engineering firm AMG, had three alternatives prepared for various configurations utilizing the existing curb to curb width of approximately 64 feet. The baseline criteria for all of the alternatives was having one lane City Council Agenda Item 9e Page 3 of 5 February 4, 2025 of vehicular traffic in each direction and the addition of bicycle lanes. The different alternatives considered buffered bike lanes, on-street parking, and a center turn lane median.
DISCUSSION
The City Council should first decide if a lane reduction project should be implemented versus the no project alternative which would leave the existing resurfacing work and paint striping from last October as is. If the Council selects the “No Project Alternative” then the Staff will cease further work, cancel the TDA grant application, and remove this project in the upcoming Capital Improvement Plan for FY 2026. The approximate cost spent to date is approximately $12,000 on consultant services. City maintenance staff will need to monitor the fading of striping on Mountaire Parkway and consider restriping earlier than typically done for a roadway with thermoplastic striping.
If the City Council would like to implement a lane reduction project, the following alternatives were developed for the Council’s consideration. The alternatives are summarized below and specific layout plans are attached for further details.
Alternatives 1 includes on-street parking, bike lanes, buffer zones, and vehicular travel lane.
A painted center two way left turn lane painted median is not included in this alternative.
City Staff believes this alternative would potentially have the most impact in reducing the travel speed of vehicles since the road is visually narrowed and would lead to some speed reductions due to delays/queues forming for turning vehicles; but it would not physically stop vehicles from swerving around into the buffer zone to pass vehicles.
ALTERNATIVE 1
City Staff recommends Alternative 2 if the City Council elects to implement a lane reduction.
This alternative includes a painted center two way left turn lane median, standard bike lanes and on-street parking. This alternative balances the use between automotive vehicles, including turning cars into driveways, bicycles, and residential parking. This alternative is the least bike friendly alternative since buffer zones are not initially included. If the Council would like to increase bicycle safety, one potential adjustment to this alternative would be to change the 7’ wide bike lane into a 5’ wide bike lane, narrow the parking width from 8.5’ to 8’, and narrow the center median from 11’ to 10’ which would gain 3’ in each direction to install a narrow 3’ wide buffer zone between the vehicle travel lane and the bicycle lane.
City Council Agenda Item 9e Page 4 of 5 February 4, 2025 ALTERNATIVE 2
Alternative 3 is the same as Alternative 2 but trades on-street parking for a wide buffer zone between the vehicle travel lane and bicycle lane. It consists of a vehicle lane, bicycle lane, buffer zone, and painted center two way left turn lane median. The main impact is the loss of on-street parking for fronting property owners.
ALTERNATIVE 3
FISCAL IMPACT
The recommended alternative alignment is estimated to be $244,000 which includes resurfacing the roadway pavement again from last year to cover up the existing temporary paint striping. Staff is applying for a TDA grant for $50,000 which will help partially fund this bicycle lane project. The City’s local contribution is estimated at $194,000 if the full requested amount from the grant is allocated. The City will use Measure J Return to Source and/or Gas Tax funds.
If the City Council decides to select a different alternative alignment (#1 or #3 or some combination) the likely overall cost is expected to slightly increase due to the additional striping for buffered bike lanes (additional longitudinal stripe and cross hatching). The overall magnitude would be an additional 15% to 20%.
CEQA IMPACT
City staff have filed a Notice of Exemption to CEQA since the proposed project is deemed Categorically Exempt in accordance with California Code of Regulations, Section 15301 Class 1 (c) – minor alteration of existing public facilities involving negligible or no expansion of existing use. In this case, it is a reduction of vehicular travel lane use, and conversion to bicycle lanes. This is consistent with changes to CEQA guidelines since the passage of SB 743 which substituted vehicle miles traveled for the old level of service metrics and promoted the benefits of reductions in greenhouse gas emissions when considering multi-modal transportation.
City Council Agenda Item 9e Page 5 of 5 February 4, 2025 Citizens can no longer challenge CEQA findings/exemptions based on slower automobile traffic or loss of parking as significant impacts.
