Planning Committee STAFF REPORT May 6, 2015 Page 2 of 4 Background In November 2011, the City of Walnut Creek applied for Measure J Program 12 TLC funding for the Northwest Walnut Creek Pedestrian and Bicycle Access project. In its application, the City proposed adding approximately 2 miles of bicycle-pedestrian improvements in Northwest Walnut Creek on the west side of I-680. These improvements include bicycle sharrows, signage, sidewalk improvements, installation of curb ramps, traffic calming through means of correcting non-conforming perpendicular spaces in the frontage of a school, pedestrian signal and sidewalk installations. The project originally had two components: 1. A 1.5-mile long set of bicycle and pedestrian improvements along Buena Vista Avenue, Parkside Drive and Hillside Avenue that would provide safer and more comfortable connections to the Walnut Creek BART Station; and 2. Pedestrian improvements to Buena Vista Elementary along Alvarado and San Juan Avenues. In May 2012, following the earlier recommendations of TRANSPAC, the Authority allocated $1 million in Measure J TLC funds in the Program 12 and 13 Programming Plan. About two years later on April 22, 2014 the Authority approved Resolution 14-33-G which appropriated $85,000 for the design of the project. Through the design process, the City divided the project into three components: 1. The San Juan Avenue Street Improvement project will close pedestrian sidewalk gaps on San Juan Avenue and improve access to Buena Vista Elementary School; 2. The Hillside Avenue Street Improvement project will close pedestrian sidewalk gaps and install bicycle facilities to connect neighborhoods in Northwest Walnut Creek to transit and the downtown areas; and 3. The Buena Vista Avenue Rehabilitation project will repave Buena Vista Avenue and also replace the roadway striping and signage to incorporate bicycle facilities. All three were part of the original application, but would be implemented through separate contracts. The San Juan Avenue and Buena Vista Avenue projects would be done during the S:\05-PC Packets\2015\05\08 Brdltr NW Walnut Creek Proj 120018.docx 8-2

Planning Committee STAFF REPORT May 6, 2015 Page 3 of 4 summer of 2015, while the Hillside Avenue project, which requires a Caltrans encroachment permit, would be completed summer of 2016. On November 3, 2014, the Authority convened a Committee to review the 65% Plans, Specifications and Estimate (PS&E) for the project. The Committee consisted of Angela Villar (Contra Costa County), Miki (Carlson, Barbee & Gibson, Inc.), and Rick ( Engineering). At that time, the City forwarded materials for Hillside Avenue and San Juan Avenue projects only, and informed Authority staff that the rehabilitation project on Buena Vista Avenue would be funded entirely with local funds. The comments on the 65% PS&E and the responses to those comments are included in Attachment B. At the end of January 2015, the City and its consulting engineers forwarded the 90% PS&E design package to the Authority and the Committee. Comments on the 90% PS&E and the responses from the City are included in Attachment C. A letter from Angela Villar, Contra Costa County, who served as Chair of the Committee, recommending approval of the peer review is included in Attachment D. In reviewing the project, Authority staff noted that portions of the San Juan Avenue project included rehabilitation elements that are not eligible for Measure J TLC funding. Specifically, the rehabilitation of San Juan Avenue did not meet the TLC program objectives, which are to encourage bicycling and walking and to foster transit-supportive, walkable infill development. In response, the City has suggested using some of the TLC funding on the bicycle and pedestrian components of the Buena Vista project. Originally, the City saw the Buena Vista project as primarily a rehabilitation project with a relatively minor portion of project funding to be used to improve bicycle facilities along the roadway. As they went through design, the City revised the Buena Vista project substantially, adding sidewalk repair, crosswalk bulbouts, and more substantial bicycle improvements. Staff agrees that these components are eligible for Measure J TLC funding, and because they were included in the original project application, allocating funding for the Buena Vista project would be consistent with the Authority s original approval. The City, however, has already completed the 90% PS&E design of the Buena Vista project and asks that the Authority exempt this project from the peer review requirements. Staff has previously exempted projects from peer review when design had already been completed and recommends that an exemption be granted for the Buena Vista project.

Planning Committee STAFF REPORT May 6, 2015 Page 4 of 4 The letter from Alex Wong, City of Walnut Creek staff, in Attachment E identifies the parts of the San Juan Avenue project that are ineligible for TLC funding. The City estimates that about $110,400 of the project s cost is not eligible. The letter also identified about $251,300 of the Buena Vista project bicycle improvements, bulbouts and filling gaps in sidewalks that are eligible for TLC funding. The following table shows the total cost of the three project components, based on the engineer s estimate and the estimated amount eligible for TLC funding. Total Cost Ineligible Eligible San Juan Avenue $664,540.15 $110,357.00 $554,183.15 Hillside Drive $358,816.68 $0.00 $358,816.68 Buena Vista Avenue $1,200,523.00 $949,295.35 $251,227.65 $2,223,879.83 $1,059,652.35 $1,164,227.48 The Program 12 and 13 Programming Plan allocated $1 million for the project, $85,000 of which has already been expended for design. The remaining $915,000 will be used to fund the eligible portions of the construction phase for all three components of the project.

Resolution 15-20-G May 20, 2015 Page 5 Attachment A (cont d.) Scope of Work The work for the Northwest Walnut Creek Pedestrian and Bicycle Access Program will be completed in three separate projects: San Juan Avenue Street Improvements, Buena Vista Avenue Road Rehabilitation and Hillside Avenue Sidewalk Gap Closure. The projects will install approximately 2-miles of bicycle and pedestrian improvements on Hillside Drive, San Juan Avenue and Buena Vista Avenue. These improvements will connect multiple locations including: Walnut Creek BART, Pleasant Hill BART, churches, parks, a museum, downtown shopping, schools, neighborhoods, central Walnut Creek, etc. SAN JUAN AVENUE STREET IMPROVEMENTS Pedestrian improvements including sidewalk gap closures, pedestrian bulbouts, crosswalk realignment, and roadway restriping will be included with improvements on San Juan Avenue along the frontage of Buena Vista Elementary School. These improvements will upgrade pedestrian facilities on the west side of San Juan Avenue, standardize lane width for the vehicular travel way, and revise striping and signage for parking and school drop-off /pick-up areas. Certain maintenance components of the San Juan Avenue Improvements and Buena Vista Avenue Road Rehabilitation projects will be paid for by local funds. BUENA VISTA AVENUE ROAD REHABILITATION PROJECT The Buena Vista Avenue Road Rehabilitation project will perform pavement repair, repave the roadway, replace damaged sidewalk and perform ADA upgrades at curb ramp locations. Additional improvements to install bicycle facilities, close pedestrian sidewalk gaps and install pedestrian bulb outs at Sandy Lane, Alvarado Avenue intersection and 3rd Avenue intersection will be performed to improve pedestrian and bicycle access. Improvements to install bicycle facilities, closing pedestrian sidewalk gaps and installing pedestrian bulb-outs have been quantified and will be paid for by the TLC funding. HILLSIDE AVENUE SIDEWALK GAP CLOSURE PROJECT The Hillside Avenue Sidewalk Gap Closure project will be funded entirely by the TLC grant. Pedestrian and bicycle improvements will be installed on the south side of Hillside Drive to close gaps to create a bicycle/pedestrian connection to existing pedestrian route through residential neighborhoods leading towards the south side of the 1-680 freeway underpass. These improvements will provide the means to connect paths for 8-9

Attachment G Quarterly Project Status Report ATTACHMENT E Jan Mar, 2015 Project Northwest Walnut Creek Pedestrian and Bicycle Access (TLC 120018) Sponsor Walnut Creek Subregion Central County Project Scope The Hillside Avenue project will improve crosswalks, filling gaps in sidewalks, and install a protected pedestrian signal at the I-680 underpass to connect to the Walnut Creek BART station. The San Juan Avenue project (near the Buena Vista Elementary School) will close a gap in the pedestrian network, modify on-street perpendicular parking stalls to 45 degree stalls, and provide curb ramps and sidewalks. The Buena Vista Avenue project replace damaged sidewalks, add ADA upgrades, and install bicycle facilities, close pedestrian sidewalk gaps and install pedestrian bulb-outs between Geary and Parkside. Project Status and Continuing Activities Construction contract for the San Juan Avenue Street Improvement project is scheduled to be awarded April 2015 with construction scheduled to between June and December 2015. The Hillside Avenue improvement project is at the 90% design level. Caltrans Encroachment Permit comments under I-680 for sidewalk installation and traffic signal upgrades are being addressed with the completed PS&E package scheduled for late 2015. Construction is scheduled for 2016. Project Issues/Areas of Concern The Caltrans Encroachment Permit work under the I-680 overpass on Hillside Drive requires the TLC project to be performed with separate construction contracts, since the work on San Juan Avenue is adjacent to an elementary school and needs to be completed prior to the start of school in 2015. Changes Since Last Quarterly Update Construction for the San Juan Avenue Street Improvement is scheduled to occur between June and October 2015. PS&E is expected to be completed in late 2015 with construction scheduled for 2016. Project Location Schedule Summary Milestone Dates Project Approval/ Complete Environmental Document Final Design 2014-2015 Right of Way & Utilities N/A Construction 2015-2016 Funding by Source ($ 000s) Funding Source Amount Measure TLC $1,000,000 Local agency funds $425,000 Total $1,425,000 Construction of the Buena Vista Avenue Rehabilitation will occur in the summer of 2015. The bicycle and pedestrian enhancement components of the project are within the project scope of the City s TLC grant and will be subsidized through TLC funding. Updated April 6, 2015 8-44
