The primary goal of the Berkshire Creek Area Improvements Project (Project) is to improve the ecological. hydrological, and recreational conditions throughout an approximate 4.7-acre area comprising the lower third of the Oak Grove area of Hahamongna Watershed Park. The Project would address the degraded conditions downstream of the Berkshire Place Storm Drain No. 12 storm drain outlet; replace asphalt with a permeable surface and native garden at the equestrian picnic area; install interpretive signage; and conduct oak woodland, riparian, and California sage scrub habitat restoration.
