1. The driveway can be constructed in the location shown on the recorded map in compliance with the requirements of Public Resources Code Section 4290 and county development standards. If it is determined that a driveway cannot be constructed for a parcel, the applicant will be required to file an amended tentative map which will provide a driveway within the parcel’s offered or deeded lot frontage as shown on the re-recorded map.
2. The driveway meets the AASHTO or Caltrans requirements for adequate sight distance to permit safe road access.
C. The road commissioner or his designee, in his discretion, may permit design exceptions to allow driveway access at other points within the parcel frontage so long as the driveway meets the requirements of Public Resources Code Section 4290, county development standards and AASHTO or Caltrans requirements for adequate sight distance, unless the access rights have been waived. If access has been waived, the driveway must be constructed in the exact location shown on the recorded parcel map or subdivision map. (Ord. 610 § 4, 2005).

14.50.070 Standards.

A. The standards for erosion control of the Erosion and Sediment Control Handbook, May, 1978, Department of Conservation, Resources Agency, state of California may be considered acceptable for the purposes of this chapter.
B. The standards for excavating and grading shall be as set forth in Chapter 70 of the Uniform Building Code.
C. Watercourses and drainage facilities that are relocated shall conform to good civil engineering practices and standards.
D. Roads shall conform to the requirements of the county road department or other approved standards. (Ord. 445 § 1(part), 1979).

14.50.075 Special circumstances.

The county engineer and road commissioner may modify the standards set forth in subsections A and B of Section 14.50.070 because of special circumstances including, but not limited to, size, shape, topography, drainage, soil type, and gradient. (Ord. 445A § 3, 1981).

14.50.080 Drainage and erosion control requirements.

A. Sediment Control. Sediment shall be retained on the site. Sediment basins, sediment traps, or similar sediment control measures shall be installed at the time of clearing and grading operations.
B. Native vegetation shall be retained, protected and supplemented wherever possible. When vegetation must be removed, the method shall be one that will minimize the erosive effects from the removal. Exposure of soil to erosion by removing vegetation shall be limited to the area required for immediate construction operations.
C. Grading operations shall be conducted so as to prevent damaging effects of sediment production on the site and on adjoining properties. Operations should be conducted during the period of May 1st through November 30th as much as possible. During the period of December 1st through April 30th, more stringent controls may be required.
D. Control of Runoff. Provisions shall be made to control the increased runoff caused by changed soil and surface conditions during and after development. To prevent excess runoff, the rate of surfacewater runoff shall be structurally retarded through use of sediment basins, silt traps or similar measures.
E. Slope Construction. Cuts shall be no steeper than 1:1 and fills shall be no steeper than 1-1/2:1 unless soil conditions indicate a different slope is necessary for stability. Erosion control measures shall be specified to provide stabilization. Slopes shall not be constructed so as to endanger or disturb adjoining property.
F. Slope Stabilization. Earth or paved interceptors and diversions shall be installed at the top of cut or fill slopes where there is a potential for surface runoff. Temporary mulching, seeding, or other suitable stabilization measures shall be used to protect exposed critical areas during construction or other land disturbance.
G. Structural Protection. Retaining walls shall be designed to retain steep embankments. Slope stabilization using flexible or rigid paving materials and channel lining are all acceptable methods of providing erosion and drainage control when designed according to good civil engineering practice and standards.
H. Grading. All land within a development shall be graded to drain and dispose of surfacewater. Where drainage swales are used to divert water they shall be vegetated or protected with rock, paving or other approved methods to prevent erosion.
I. Protection of Watercourses. Fills placed against watercourses shall have suitable protection against erosion during flooding. Excavated materials shall not be deposited or stored in or alongside any river or watercourse where the materials so deposited are likely to be washed away by high water or storm runoff.
J. Disposal of Cleared Vegetation. Vegetation removed during clearing operations shall be disposed of as follows:
1. Chipping all or some of the cleared vegetation for use as mulch or compost on the site;
2. Burning under fire permit;
3. Removing the material to an approved disposal site;
4. Burying the material on site except below building sites or parking areas;
K. Disposal of Excavated Materials. Excavated materials removed shall be disposed of as follows:
1. Topsoil may be stockpiled on the site for use on areas to be revegetated. Stockpiles shall be located far enough from streams or drainageways so as to insure that surface runoff cannot carry sediment downstream;
2. Backfill and compact soil promptly into trenches and pits to reduce the risk of erosion;
3. Apply mulch or protective coverings on stockpiled material which will be exposed to rains;
4. Remove material from the site to an approved location. (Ord. 445 § l(part), 1979).

14.50.090 Report and appeal to the board of supervisors.

A. A hearing may be set by the board of supervisors for purposes of reviewing the permit application if:
1. The applicant has been denied a permit or disagrees with the conditions imposed by the approving agency and requests an appeal to the board;
2. Any other person directly or adversely affected by the decision to grant a permit who requests a hearing within fifteen days after the mailing of notice of issuance of the permit. The filing of any appeal shall stay the issuance of the permit until such time as the appeal has been decided by the board. Notice of permit issuance shall be provided by mail to adjacent landowners within three hundred feet of the subject property in those cases where the county engineer determines that a change in the area drainage pattern may result from the work contemplated.
B. Cost of filing an appeal shall be thirty-five dollars. (Ord. 445 § l(part), 1979).

14.50.100 Inspection.

A. The county engineer and his authorized representatives shall conduct such inspections as deemed necessary to insure compliance with the approved plans and conditions of the permit. The county engineer or his representative shall have the right of entry upon the premises, the right of stoppage of any construction operation in violation of the permit and the right of clearing out or opening the stoppage of any drainage facility that is deemed to be contrary to the provisions of the permit or this chapter.
B. 1. Inspections shall be conducted upon notification to the county engineer as follows:
a. After sediment control measures have been taken and at the time that clearing and grading operations begin;
b. Before pouring concrete or placing pavement or channel lining;
c. Prior to October 15th on erosion control work;
d. After vegetation removal and grading operations are complete or are temporarily stopped;
e. When slope stabilization and watercourse protection work are complete.
2. Other inspections shall be made as required by the time schedule of operations and as determined by the inspector. (Ord. 445 § l(part), 1979).
