Contra Costa County Public Works Department (County) proposes to improve the recreational sports facilities located in Montalvin Park. These improvements will benefit the residents in the Montalvin neighborhood, who rely on Montalvin Park for outdoor recreational activities. The improvements will also encourage youth to utilize the facilities in a positive way, and will enhance the overall aesthetic appearance of the park. Improvements will be conducted in four phases which include: additional parking stalls and path improvements with Americans with Disabilities Act (ADA) features; new shade structure, picnic tables, benches, fitness stations; converting the existing tennis court to basketball courts, renovation of the turf fields, and relocation of a portable toilet area. Ground disturbance and excavation will occur to an anticipated depth of approximately 1-2 feet. Vegetation removal is anticipated, including removal of 6 non-native trees. If any work is needed within the nesting bird season, then nesting bird surveys will be conducted. No utility relocations, traffic control, or real property transactions are anticipated. The improvement work is anticipated to begin August 2022 and may take multiple years for different phases. This project is partially funded by the California Proposition 68 Per Capita Program Grant.
