A. 
Requirements of this section for submitting engineered plans and specifications and/or drainage reports may be waived or modified for projects to install storm water management practices for residential BMP retrofit projects or, at the sole discretion of the director, for other small grading projects.
B. 
Each application for a grading permit shall include the following:
1. 
A completed application form;
2. 
Three complete sets of grading plans and specifications (as applicable);
3. 
Profiles, cross-sections, and specifications as required;
4. 
A drainage report as required by the department;
5. 
The application fee as determined by the city council;
6. 
Where applicable, evidence of coverage, or application for coverage, under an NPDES general construction permit.
C. 
The plans and other documents will be reviewed by the department. The applicant and/or project engineer will be notified of any necessary changes to the plans. When the plans and other documents have been approved by the department, a grading permit will be issued for the project. All work must be done in strict conformance with the approved plans and documents. The approved plans shall not be changed or altered except in accordance with the provisions of this chapter.
D. 
Drainage reports are required for all commercial projects, subdivisions, parcel maps, environmental improvement projects, drainage improvement projects, projects involving disturbance to stream environment zones, and for other projects at the sole discretion of the director. The report shall be prepared by a civil engineer registered in California. The level of detail required in the report depends on the size, type, and location of the proposed grading, and shall be determined by the director and authorized designees.
(Ord. 1000 § 1; Code 1997 § 36-27)
A. 
All plans and specifications shall be prepared, signed and stamped by a civil engineer for any project where the proposed grading:
1. 
Requires cuts and fills involving a combined total of 350 cubic yards of dirt or more, or requires fill exceeding five feet in depth; or
2. 
Includes the creation or aggravation of an unstable slope condition; or
3. 
Requires a cut or fill that is situated so as to cause unduly increased soil pressure or reduce earth support upon adjacent structures or property; or
4. 
Requires construction of any retaining wall or other slope stabilization measure which, together or individually, is over four feet in height.
5. 
Includes the construction of any:
a. 
Infiltration basin or system capturing runoff from more than 2,500 square feet of impervious surfaces; or
b. 
Underground water quality treatment vault or system; or
c. 
Culverts, drain inlets, or other structural BMPs for conveying off-site drainage or for sediment control; or
d. 
Substantial alteration to any existing drainage course; or
e. 
Access road serving more than one existing or potential residence(s); or
f. 
Vehicular bridge.
B. 
At the sole discretion of the director, plans and specifications prepared and signed by a civil engineer, will be required for any other project which could endanger the public health, safety and welfare.
(Ord. 1000 § 1; Code 1997 § 36-28)
Grading plans and specifications shall be prepared and signed by a civil engineer, as provided herein.
A. 
The plans shall include the following:
1. 
All plans shall be on 24-inch by 36-inch sheets unless otherwise approved, and shall be drawn at a scale no less than one inch equals 20 feet, unless a different scale is approved by the director;
2. 
A title block. Plans shall be entitled "grading plan" and state the purpose of the proposed grading and the name of the engineer or firm by whom this plan is prepared, owner's name and address, the site address, and assessor's parcel number (APN);
3. 
A vicinity sketch (not at map scale) indicating the location of the site relative to the principal roads, lakes and watercourses in the area;
4. 
North arrow and scale;
5. 
A site plan indicating the extent of the work and any proposed divisions of land;
6. 
The complete site boundaries (i.e., property lines) and locations of any easements and rights-of-way traversing or adjacent to the property;
7. 
The location of all existing or proposed roads, buildings, wells, pipelines, watercourses, and any other structures, facilities, and features of the site, as well as the location of all improvements on lots within 50 feet of the proposed work;
8. 
Location and nature of known or suspected soil or geologic hazard areas, including but not limited to groundwater cleanup sites, landslides, etc.;
9. 
The source of survey information, and sheets showing accurate contour lines of the existing terrain and proposed finished grade at intervals not greater than two feet, or spot elevations 25 feet on center showing all topographic features and drainage patterns throughout the area where the proposed grading is to occur relative to a bench mark established on site. The contour lines/spot elevations shall be extended to a minimum of 50 feet beyond the affected area, and further, if needed, to define intercepted drainage, and shall be extended a minimum of 100 feet outside of any future road right-of-way. The department may require more detail to allow review;
10. 
Approximate location of cut and fill lines extent and finished slopes of all proposed grading and the limits of grading for all proposed grading work, including borrow and stockpile areas;
11. 
Location, width, direction of flow and approximate location of any watercourses or drainage ways including tops and toes of banks, and location of SEZ and SEZ setbacks;
12. 
Approximate boundaries of any areas with history of flooding;
13. 
Cross-sections, profiles, elevations, dimensions, and construction details based on accurate field data as may be required after initial review of plans;
14. 
Construction details for roads, watercourses, culverts, bridges and drainage devices, retaining walls, cribbing, dams, and other improvements existing or to be constructed, together with supporting calculations and maps as may be required after initial review of plans;
15. 
Proposed provisions for storm drainage control and any existing or proposed flood control facilities or storm water management practices near the grading;
16. 
A detailed erosion and sediment control plan including specific locations, construction details, and supporting calculations for temporary and permanent structural BMPs and facilities;
17. 
A revegetation plan, including temporary erosion control plantings, permanent slope plantings, replacement of temporary groundcover, and irrigation facilities.
B. 
Additional supporting information which may be required includes, but is not necessarily limited to:
1. 
An estimate of the quantities of disturbed area, excavation and fill;
2. 
The location of any borrow site or location for disposal of surplus material;
3. 
A projected schedule of operations, including, as a minimum, the dates of:
a. 
Commencement of work;
b. 
Start and finish of rough grading;
c. 
Completion of drainage facilities;
d. 
Completion of work in any watercourse;
e. 
Completion of erosion and sediment control facilities;
f. 
Completion of hydro mulching and other landscaping. If rough grading is proposed between October 15th and May 1st, a more detailed schedule of grading activities and use of erosion and sediment control facilities may be required;
4. 
Itemized cost estimate of the proposed grading and related work;
5. 
A drainage study;
6. 
Geotechnical investigation report and recommendations addressing the proposed work.
(Ord. 1000 § 1; Code 1997 § 36-29)

Proposed modifications of an approved final plan shall be submitted to the department for written approval.
B. 
All necessary soils and geological information and design details shall accompany any proposed modification.
C. 
The modification shall be compatible with any subdivision map or land use requirements.
(Ord. 1000 § 1; Code 1997 § 36-31)
Implementation of erosion and sediment control plans shall be based on the season of the year and the stage of construction at forecasted periods of rainfall and heavy storms. Erosion and sediment control plans shall allow for possible changes in construction scheduling, unanticipated field conditions, and relatively minor changes in grading. Modifications to plans may be required after initial plan approval. (See SLTCC § 7.20.600 on erosion and sediment control plans.)
