16.20.130 Securities.
Approvals for grading shall not be valid and work shall not be started until the required securities have been provided. Securities shall remain in effect one winter after final inspection and approval. All expenditures by the County for corrective work necessary because of the permittee’s failure to comply with the provisions of the approval and this chapter shall be charged against the security.
(A) If a grading is in excess of 2,000 cubic yards the permittee shall provide a cash deposit, time certificate of deposit, or equivalent security, acceptable to the County, payable to the County to insure compliance with the provisions of the approval and this chapter.
(B) If deemed necessary by the Planning Director, a similar security, acceptable to the County, may be required for grading operations of less than 2,000 cubic yards.
(C) The amount of security for grading shall be based on the number of cubic yards of material of either excavation or fill, whichever is larger, plus the cost of drainage or other protective devices. The minimum amount required shall be computed as indicated in the following schedule:
(1) Two thousand to 10,000 cubic yards: $0.50 per cubic yard, plus the cost of drainage or other protective devices.
(2) Ten thousand and one cubic yards or more: $5,000 plus $0.25 per cubic yard for each additional cubic yard in excess of 10,000, plus the cost of drainage or other protective devices.
(D) No separate grading security except for security required for winter grading operations shall be required for work on which a final subdivision map has been recorded (or a tentative subdivision map has been approved subject to a specific condition that grading will be permitted prior to recording of the final map); provided, that all of the contemplated grading is shown on approved improvement plans pursuant to Chapter 14.01 SCCC and the amount of the subdivision improvement, performance, labor and material securities is sufficient to cover all grading.
(E) A separate security for any grading operations authorized during the winter, between October 15th and April 15th, may be required if deemed necessary by the Planning Director. [Ord. 3599 § 7, 1984; Ord. 3438 § 1, 1983; Ord. 3321 § 1, 1982; Ord. 2500, 1977].
16.20.140 Design standards for excavations.
(A) Slope. Cut slopes shall be no steeper than one and one-half horizontal to one vertical. Steeper slopes may be allowed if the Planning Director determines they will be stable or if a civil engineer or engineering geologist provides a written statement that the site has been investigated and that in his opinion the proposed deviation will be and remain structurally stable. The tops of cut slopes shall be rounded off so as to blend in with the natural terrain. (See Figure 3.)
(B) Drainage and Terraces. Drainage and terraces shall be provided as required by SCCC 16.20.170.
(C) Vegetation Removal. No vegetation removal or grading pursuant to a permit will be allowed which will result in erosion. Vegetation removal shall conform to SCCC 16.22.080. [Ord. 3321 § 1, 1982; Ord. 2500, 1977].

(A) General. Unless otherwise recommended in the soil engineering report approved by the Planning Director, fills shall conform to the provisions of this section.
(B) Fill Location. Fills shall not be constructed on natural slopes steeper than two to one unless a civil engineer devises a method of placement which will assure the fill will remain in place. The toe of a fill shall be no closer than 12 feet horizontally to the top of existing or planned cut slopes (See Figure 3).
Figure 3
(C) Preparation of Ground for Fill. The ground surface shall be prepared to receive fill by the removal of topsoil and other unsuitable materials and by keying into sound bedrock or other suitable material.
(D) Material Permitted. Earth material free from tree stumps, organic matter, trash, sod, peat and similar material shall be used in fills. Rock, cobbles, and similar material shall be distributed and not nested or piled together, and pieces larger than 12 inches in greatest dimension shall not be used unless a method of placement is approved by the Planning Director. Organic material may be used in the top 12-inch layer of fills to aid plant growth.
(E) Fill Slopes. No fill shall be made which creates an exposed surface steeper in slope than two horizontal to one vertical. The Planning Director may allow a steeper slope or require a flatter slope if he finds this consistent with stability and safety.
(F) Compaction of Fills. All fills shall be compacted to a minimum of 90 percent of relative maximum density as determined by ASTM D-1557-70, or CALTRANS test method number California 216. Compaction tests may be required.
(G) Drainage and Terraces. Drainage facilities and terraces shall be provided as required by SCCC 16.20.170. [Ord. 3321 § 1, 1982; Ord. 2500, 1977].

These requirements may be modified for emergency access, temporary roads, or roads leading to an agricultural building or well site if approved in writing by the Planning Director.
(B) Width of roadbed for a roadway shall be 16 feet minimum; width of a driveway shall be 12 feet minimum. Where it is environmentally infeasible to meet these criteria (due to excessive grading or tree removal), a 12-foot-wide all-weather road with 12-foot-wide by 30-foot-long turnouts located approximately every 500 feet may be approved with the approval of the fire department. The distance between turnouts may be adjusted at the discretion of the Planning Director if deemed appropriate for reasons of topography, environment or emergency access.
(C) Minimum centerline radius shall be 35 feet. (Exception: Driveways which serve as access to any habitable structure and which are 150 feet or less from the main road.)
(D) The maximum grade of the road or driveway shall not exceed 15 percent; however, grades of up to 20 percent are permitted for up to 200 feet at a time.
(E) The structural section shall consist of a minimum five inches of baserock, Class II or Class IV. Class IV aggregate base should have a minimum R value of 50, and not more than 10 percent of the aggregate shall pass the number 200 sieve.
(F) Where the subgrade is designated as an expansive clayey soil, the structural section should be determined using the California Design Procedure.
(G) The aggregate base required by these design standards can be omitted if the Planning Director determines that the native material provides sufficient bearing capacity for all weather use.
(H) Road surfacing shall meet the following standards, based on road gradient: zero to 10 percent gradient—two inches of drain rock compacted into a four-inch sub-base of Class II baserock; 10 to 15 percent gradient—oil and screenings; greater than 15 percent gradient—one and one-half inches asphaltic concrete. (Exception: aggregate base and asphaltic concrete may be omitted if a structural section of four-inch concrete is used.)
(I) Asphalt or concrete berms or their equivalent may be required to control drainage. Discharge shall be at points of natural drainage courses with energy dissipaters installed where necessary to prevent erosion.
(J) Entrances from private roads or driveways into private roads shall be limited in gradient as shown by Figure 4.
Figure 4. Private Road or Drive
(K) Any roadway or driveway which is more than 300 feet long and a dead end shall have a turn-around area with a minimum of 32 feet radius, or equivalent.
(L) A horizontal clearance of 16 feet and a vertical clearance of 14 feet shall be maintained on all roadways, driveways, and turnouts.
(M) Where a private driveway will connect to a County-maintained road, an encroachment permit shall first be obtained from the Public Works Department. [Ord. 4678 § 1, 2002; Ord. 4578 § 5, 1999; Ord. 3599 § 8, 1984; Ord. 3438 § 1, 1983; Ord. 3321 § 1, 1982; Ord. 2500, 1977].
