    • i. Where standard foundations and conventional construction techniques are satisfactory.

    • ii. On or off-site areas where geological hazards may exist; and areas where hazards can be mitigated through foundation design.

    • iii. Areas where geologic suitability is uncertain without additional geotechnical and/or subsurface investigations.

    • iv. Identify stable on-site access roads and/or driveway routes to the buildable areas.

    • v. If the proposed building sites will be served by septic systems, the report should address on and off-site land stability in relation to leachfield sites and the possibility of instability being induced by leachfield construction.

  2. When off-site roadways are proposed, the geological report shall discuss the suitability of and the soils design criteria for constructing roads in the proposed locations. The design criteria shall at a minimum discuss and make recommendations on:

    • i. Maximum permissible cut and fill slopes.

    • ii. Relative densities to be achieved in constructing fills.

    • iii. Drainage channel protection to preclude erosion.

    • iv. Any earth retaining structures which are needed to assure a minimum of road instability.

    • (d) Unpaved streets: Gravel road surfaces may be permitted by the review authority provided that in each case the applicant improves, or bonds for improvement, per Subsection (c) above, a street section equal in length to those street frontages serving the applicant’s lot frontages, in a location within the “SOS” district and to a standard determined by the Review Authority. In no case shall the required improvements be less than an all-weather chip seal street twenty (20) feet in width. The provisions of this Subsection shall not be applicable when more than ten (10) dwellings utilizing the same access route have been constructed in the “SOS” district.

    • (e) No street constructed, altered or reconstructed according to the provisions of this Article shall be accepted for maintenance by the County of Lake unless built to full county specifications for subdivision roads.

    • (f) Indemnification agreement: The permittee shall enter into an indemnification agreement, holding Lake County harmless from any liability for any improvements authorized by this permit satisfactory in form and content to County Counsel.

    • (g) Road maintenance agreement: All applicants proposing to construct or utilize for access a non-county maintained road shall enter into a property owners’ road maintenance agreement, approved as to form by the Planning Department, ensuring long-term repair and maintenance of the street, including dust control by property owners.

  • 25.24 Criteria : The purpose of this district is to insure that development of older subdivisions will provide basic health and safety services. To this end all use permit applications seeking reduction in the performance standards should be reviewed taking into account the following criteria:

    • (a) The adequacy and compatibility of proposed and existing improvements.

    • (b) The provision of basic health and safety requirements.

    • (c) Adherence to the performance standards will not result in unacceptable aesthetic or environmental degradation.
