CHATSWORTH PARK SOUTH REMEDIAL ACTION PLAN - MITIGATED NEGATIVE DECLARATION (MND)
Council District: 12 Valley Region
Project Address: The Project site is in the northwestern corner of the San Fernando Valley, in the Chatsworth community of the City of Los Angeles. Locally, the site is the 72-acre Chatsworth Park South located at 22360 W. Devonshire Street, and is bounded to the north, west, and south by the Santa Susana Mountains and Santa Susana Pass State Historic Park. The Project site is bounded to the east by a residential neighborhood.
Project Description: The proposed Project consists of the implementation of a Remedial Action Plan (RAP) that will be approved by the California Environmental Protection Agency Department of Toxic Substances Control (DTSC) under a Voluntary Cleanup Agreement with LADRP. The RAP proposes to cap in-place the soil impacted principally by lead and polycyclic aromatic hydrocarbons (PAHs) discovered in the park from a former Small Arms Firing Range. The surface cap would provide a permanent solution that reduces the accessibility and mobility of the impacted soils, and therefore, the threat to human health and the environment. The surface cap would be installed over remediation areas and would include utility clearance, security measures, rough grading and excavation, installation of a drainage system, construction of a surface cap, and installation of fencing. The proposed Project would also grub and remove non-protected, non-Heritage trees, protect remaining trees, and mitigate demolition of trees with construction of native groves on-site. The existing parking lot would be expanded and included as part of the surface cap. A rocky outcrop on-site would be grubbed of shrubs and vegetation, then scoured and vacuumed. Drainage on-site would be improved to control runoff from upslope areas and protect the surface cap. Contaminated soils and wastes would be hauled off-site and would be disposed of at appropriate solid waste facilities.
