The proposed improvements include widening of travel lanes, installation of bicycle lanes and sidewalks/pedestrian path, and enhancement of existing street landscaping. Engineering work has begun and three project alternatives were developed for the segment of Dublin Boulevard fronting the Dublin Sports Grounds between Civic Plaza and Dublin Court. Staff will present the three project alternatives and is requesting City Council direction. Staff will proceed with the preferred alternative for further engineering and environmental work. • FINANCIAL IMPACT: The Dublin Boulevard Improvement Project — Civic Plaza/Sierra Court to Dublin Court (CIP #960026) includes a budget for engineering work in the 2012-2017 Capital Improvement Program. Right of way acquisition and construction phases of the project are currently unfunded. . RECOMMENDATION: Staff recommends that the City Council direct staff to proceed with further engineering and environmental work for Alternative #2. cam.4 Submitted By Reviewed By Director of Public Works Assistant City Manager • • • • Page 1 of 3 ITEM NO. 8.1 DESCRIPTION: The City's 2012 -2017 Capital Improvement Program (CIP) includes a budget for preliminary engineering work to improve Dublin Boulevard between Civic Plaza /Sierra Court and Dublin Court, under CIP No. 960026. The proposed improvements include widening of travel lanes, installation of bicycle lanes and sidewalks /pedestrian path, and enhancement of existing street landscaping. In February 2012, the firm of Bellecci and Associates was hired to perform preliminary engineering work. Part of their scope is to develop three alternatives for the section of Dublin Boulevard fronting Dublin Sports Grounds. The three project alternatives are as follows: • Alternative #1: This alternative consists of three lanes for each direction of travel, 5 -foot bicycle lanes and standard 8 -foot sidewalks. A 4.5 -foot landscape buffer is proposed along the Sports Grounds parking lot to enhance the parking lot area. The street widening on the north side will accommodate three westbound travel lanes, 5 -foot bicycle lane and standard 8 -foot sidewalk next to the street curb. To accommodate the widening on the north side, an additional 5 feet of right of way will be required and typical for all three alternatives. On the south side, the proposed sidewalk along the Sports Grounds also adjoins the street curb and a portion (5 feet) will encroach onto the park property. Further to the east, the new sidewalk will require expansion of an existing drainage culvert adjacent to Dublin Court. The estimated cost of Alternative #1 is approximately $2,700,000. • Alternative #2: This alternative consists of three lanes for each direction of travel, 5 -foot bicycle lanes, a 5.5 -foot rain garden /landscape area fronting the Sports Grounds and a 7- foot pedestrian pathway along the northerly edge of the park fronting Dublin Boulevard. The proposed pathway will be designed to meander along the northerly edge of the park east of the parking lot and landscaped to blend in with the park. The path will then be connected to a pedestrian bridge over the Zone 7 drainage canal next to Dublin Court to minimize impacts to the flood control channel. The estimated cost of Alternative #2 is approximately $2,670,000. • Alternative #3: This alternative consists of three lanes for each direction of travel, 5 -foot bicycle lane in the westbound direction, a 6 -foot rain garden /landscape area along the Dublin Sports Grounds area and a 12 -foot Class I bicycle path along the park connected to a 12 -foot wide pedestrian bridge over the Zone 7 flood control canal. The Class I bicycle path is to be shared by bicyclists and pedestrians within this stretch of the roadway. The estimated cost of Alternative #3 is $2,640,000. Impacts to Sports Grounds Parking Lot: The three alternatives were studied for possible impacts to the Sports Grounds parking lot, which was a specific concern highlighted by the City Council in February 2012. The existing parking lot configuration has a total of 166 parking stalls. The Consultant studied the parking lot layout and was able to provide a total of 169 parking stalls for Alternatives #1 and #2, and 166 parking stalls for Alternative #3 by redesigning the parking lot circulation and increasing the number of compact parking stalls as allowed by the City Zoning Ordinance for off - street parking. Any of the three project alternatives will maintain, if not increase, the number of parking stalls available for public use. Page 2 of 3 Possible Undergrounding of Existing Overhead Utilities: Overhead utilities currently exist along Dublin Boulevard between Civic Plaza /Sierra Court and Dublin Court; and some in the community believe their presence to be an eyesore to the motoring public, bicyclists and pedestrians as they pass by the Sports Grounds area. The consultant has recommended that staff consider undergrounding this segment of Dublin Boulevard since the overhead utilities adjoins the Sports Grounds area. Furthermore, this is the last segment of Dublin Boulevard between San Ramon Road and Fallon Road that is not undergrounded and removal of the overhead utilities will create a consistent appearance to the Dublin Boulevard corridor, the City's primary east -west arterial. This segment of Dublin Boulevard is currently #2 on the Rule 20A Priority List and under a separate report to the City Council on this agenda, Staff is recommending that the City Council consider re- prioritizing this segment of Dublin Boulevard in the usage of City Rule 20A funds. Discussions with the National Park Service: As Dublin Sports Grounds was deeded to the City by the Federal government with the condition to permanently use it as a park, the City is required to report to the National Park Service (NPS) any proposed alteration or improvements to the park. Staff presented the three alternatives to NPS for its review and conveyed that the City intends to keep the road within the existing road right of way and would not involve any incursion into the park or conveyance of property rights. Furthermore, the pedestrian pathway /sidewalk that would be constructed in the park would not displace any existing recreational use, would remain under ownership of the City and would serve to provide a pedestrian access path in the park. Based on these conditions, the National Park Service has commented that the City would remain in compliance with the terms of the deed and the associated program of utilizing the property park purposes. Although the National Park Service did not state a preferred alternative, the pedestrian path alternative (Alternative #2) would be more favorable to park users as it would supplement pedestrian access to the park, which was highlighted as an amenity by the NPS. Based on staff's discussions with the National Park Service, the Parks and Community Services Department and evaluation of each alternative, Staff recommends that the City Council direct staff to proceed with Alternative #2 for further engineering and environmental work. NOTICING REQUIREMENTS /PUBLIC OUTREACH: Staff plans to have a separate public outreach /workshop to present the project to the public. Stakeholders including property owners and businesses within the limits of the study will be invited to attend. ATTACHMENTS: 1. Location Map 2.
