Master Plan of Drainage

The Town of Yucca Valley Master Plan of Drainage is a comprehensive drainage and flood control plan providing a guide for orderly development of flood control facilities to improve the physical environment of the Town and assuring public safety and adequate flood protection of property. Contained within the report is watershed review and evaluation, including natural drainage courses, floodplains and existing drainage facilities; detailed hydrologic and sediment yield studies, sizing of regional, secondary and local facilities; improvement recommendations, preparation of plan and profile drawings, and cost estimates.
