This is a drainage that the Bay Trail will need to cross. Each year the Montalvin Manor neighborhood near Montalvin Park floods due to poor drainage outside of the neighborhood boundary. Stormwater from the neighborhood drains through a County maintained storm drain system from the neighborhood under the BNSF Railroad and then into a natural creek where it drains into a stormdrain pipe under the Union Pacific Railroad and then out to the Bay. The creek portion of the drainage between the two railroad tracks is on the old steel plant property owned by Point Pinole Properties and is to be deeded to the East Bay Regional Park District as part of their developmental requirements. One resolution to the drainage problem would be to restore the tidal flows into the section of the creek between the railroad tracks. This would involve improving the drainage pipe under the Union Pacific Railroad and excavating out a portion of the creek area between the railroad tracks to create a wetland and habitat area. When the Park District designs and constructs the Bay Trail in this area, they will need to mitigate the impact on the environment their construction activities will create and they will need to find mitigation sites to mitigate for their construction. This drainage area between the railroad tracks would make a great mitigation site for the Bay Trail project and at the same time solve the drainage problem for the Montalvin Manor neighborhood. The East Bay Regional Park District will be requested to incorporate resolution of the drainage in the area as part of their Bay Trail project. The Union Pacific Railroad will also need to cooperate by providing an access easement to replace/redesign the existing culvert under their tracks. Various permitting agencies will also need to review and approve plans to correct the drainage problem. An environmental evaluation of the restoration will be needed which may uncover other design constraints. The County's position has always been that part of the drainage problem was the responsibility of the property owner between the railroad tracks. When the Park District takes over ownership of the property, then the Park District will also assume this drainage problem. By designating this site as mitigation for the Bay Trail, we will be able to enhance the local environment and solve a drainage problem at the-same time. The County/East Bay Regional Park District Liaison Committee discussed this issue at its September 18, 2000, meeting. The Park District indicated their intent to evaluate the Montalvin Manor drainage as part of the Bay Trail project mitigation. The committee supports the concept of including the Montalvin drainage into the Bay Trail project as project mitigation and requests the Park District incorporate the Montalvin Manor drainage as a component of the Bay Trail project. Consequences of Negative Action: The County would not request that the East Bay Regional Park District take formal action to include the Montalvin Manor drainage into their Bay Trail project.
