RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute, on behalf of the County, a joint exercise of powers agreement with East Bay Regional Park District (EBRPD), effective April 20, 2021, to require EBRPD to pay the County approximately $25,000, and to allocate project-related responsibilities between the County and EBRPD, in connection with the extension of the Iron Horse Trail and the Marsh Drive Bridge (#28C442) Replacement Project (Project), Concord area. County Project No. 0662-6R4119 / Federal Project No. BRLS 5928(128) [District IV & V]

FISCAL IMPACT:

The estimated cost for the work associated with this agreement is $25,000. All costs associated with this work will be paid for by EBRPD.

BACKGROUND:

The Project proposes to replace the bridge on Marsh Drive (Bridge No. 28C442) over the Walnut Creek Channel in both the unincorporated area of Contra Costa County and the City of Concord.

BACKGROUND: (CONT'D)

EBRPD operates the Iron Horse Trail that starts at the southeast edge of the Project. EBRPD is in the planning stage of its project to extend the Trail over Walnut Creek, north across Marsh Drive, and then further north along the levee access road. At EBRPD’s request, County will accommodate EBRPD’s Trail extension by including in its Project a 10-foot clear dimension Class I multi-use path on the southern side of the bridge. This agreement provides for apportionment of the duties and costs between the County and EBRPD with respect to the Project. EBRPD will be 100% liable for the local share of the costs to include the multi-use path on the southern side of the bridge.

The agreement also discusses EBRPD’s responsibility to provide a connecting trail within five (5) years including a mid-block crossing of Marsh Drive at their cost. EBRPD will be responsible for keeping and maintaining the portion of the trail in road right of way in a clean and safe condition, including the removal of graffiti, vandalism, trash, and other foreign debris as provided in future license agreement with the County.

CONSEQUENCE OF NEGATIVE ACTION:

If the agreement is not approved, construction of the Project will be halted, as the bridge cannot be replaced as proposed without provisions for the trail facilities and the federal funds will be lost.
