Lake County Zoning Code § 21-37 Regulations

37.1 Purpose: To preserve, protect and restore significant riparian systems, streams and their riparian, aquatic and woodland habitats; protect water quality; control erosion, sedimentation and runoff; and protect the public health and safety by minimizing dangers due to floods and earth slides. These purposes are to be accomplished by setting forth regulations to limit development activities in significant riparian corridors and through the establishment of an administrative procedure for the granting of exceptions from such regulations.

Within the “WW” Waterway combining district, all uses of land shall comply with the regulations of the base zoning district and with the additional regulations of the “WW” combining district.

37.2 Applicability: This district may be applied on properties containing the following characteristics as defined in this Section:
- (a) Streams identified as “Natural Areas”, Figure V-5, Lake County General Plan.
- (b) Streams identified as “Critical Resource and Conservation Areas”, Figure V-6, Lake County General Plan.
- (c) Perennial streams: Any watercourse designated by a solid line symbol on the largest scale United States Geological Survey map most recently published. Perennial streams normally flow throughout the year.
- (d) Intermittent streams: Any watercourse designated by a dash and three dots symbol on the largest scale United States Geological Survey map most recently published. Intermittent streams normally flow only in direct response to rainfall and are dry for large parts of the year.
- (e) Areas adjacent to those locations identified in Subsections (a) through (d) above that include:
  1. Wetlands: Those areas that are inundated or saturated by ground or surface water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs and similar areas.
  2. Riparian vegetation: Those plant species that typically occur in wet areas along streams or marshes. Characteristic species are: Fremont Cottonwood (Populus fremontii), White Alder (Alnus rhombifolia), Box Elder (Acer negundo), Dogwood (Cornus nuttallii), Willow (Salix), Big leaf maple (Acer macrophyllum).
