The Sensitive Habitats Protection Ordinance:
This ordinance was designed to minimize disturbance in sensitive habitats and to protect these
areas for their genetic, scientific, and educational value. The ordinance states that:
No toxic substance that will have adverse effects on the biotic community can be used in a
sensitive habitat. In some instances, such substances can be used for agricultural purposes but
only if mitigation measures can ensure protection.
No development activities or land disturbance can occur in a sensitive habitat until a biotic
review has been completed. This review determines what kinds of development activities can
be conducted and what mitigation measures may be necessary to ensure protection of the habitat.
Development activity includes any action that results in disturbance to rare, endangered, or
locally unique plants and animals or to their habitats. Development includes, but is not limited
to:
- building, reconstruction, or alteration of structures on land, in or near natural bodies of water
- grading, land clearing
- change in density (including land divisions) or intensity of land use
These activities may be restricted depending on the specific sensitive habitat under consideration.
Development may be permitted as long as the habitat remains undisturbed; permitted as long as
mitigation measures can correct any resulting adverse effects; or prohibited.
Biotic Review
The applicant submits project plans and pays a fee to the Planning Department. A plot plan must
show the location and type of existing and proposed development, property lines, features such
as roads, gullies, significant vegetation, and other pertinent information.
Plans will be reviewed against County-maintained maps to see whether the site lies within a
mapped sensitive habitat.
The Review may consist of one or more of the following:
- A biotic presite: a preliminary site visit by County staff to determine if the site lies within a
sensitive habitat
- A biotic assessment: a brief review of on-site biotic resources conducted by a County-contracted biologist
- A biotic report: (an in-depth study) will be required if the biotic assessment indicates that
more information is needed. This report will be prepared at the applicant's expense by a
professional biologist (the County has a list of biologists and revegetation specialists familiar with County report and plan preparation requirements.)
The biotic report must be written according to County guidelines.
The biotic report will be reviewed by a biologist contracted by the County for this purpose. If
the project will impact a State or Federally listed species, review and approval by the State
Department of Fish and Game and/or the U.S. Fish and Wildlife Service will be required.
Result of Review:
If the biotic review or report indicates that development may be permitted in a sensitive habitat, the project may be conditioned to avoid certain areas, to mitigate for impacts, or both
Mitigating Conditions
The developer will be required to compensate for any significant effects on the environment, as
determined by the County's Environmental Coordinator. In addition, the developer may be
required to:
- Deed an easement to the County to protect the undisturbed portion of a sensitive habitat:
and/or,
- Restore any portion of a sensitive habitat which has been degraded; and/or,
- Limit the portion of the site that will be disturbed; and/or,
- Restrict land use. For example, livestock grazing may be prohibited.
Other conditions specific to the site and project may be required by the Environmental
Coordinator based on information contained in the biotic assessment or biotic report.
Exemptions:
Exemption from the requirements of the Sensitive Habitat Protection Ordinance include:
- Existing commercial agricultural operations.
- Projects which are determined by the Planning Director to have received sufficient biotic
review during the granting of a Riparian Exception for the project site.
- Projects for which an Environmental Impact Report is required which includes biotic review
through the California Environmental Quality Act.
Violations:
Violation of the Sensitive Habitat Ordinance or the conditions on a biotic permit may result in
the issuance of a Notice of Violation, which describes the actions necessary to correct the
problem and may include restoration of the area to its original condition. If the required
corrective actions are not taken promptly, the Notice of Violation is recorded on the title to the
property and becomes part of the public record. In addition, the current property owner is subject
to a levy of all enforcement costs incurred by the Code Compliance staff in obtaining compliance
as well as the possible imposition, through legal action, of penalties of up to $2,500 a day while
the violation exists.
Appeals
The usual County Planning appeal process is available to any applicant who is dissatisfied with a
biotic permit decision (see the "Planning Appeals" brochure).
