A. 
Civil Engineer. It shall be the responsibility of the civil engineer who prepared the grading plans to incorporate the applicable recommendations from the soil engineering and geology reports and to incorporate any city engineer approved alternative concept grading plan into the grading plan.
B. 
The civil engineer shall be responsible for establishing line and grade for the grading and drainage improvements and shall act as the coordinating agent in the event the need arises for liaison between the other professionals, the contractor and the city engineer. The civil engineer shall also be responsible for the preparation of plan revisions, and upon completion of the work, the submission of as graded drawings incorporating all changes and/or additions made during construction. Prior to the release of building permits for any given lot or lots, the civil engineer shall submit a written statement as evidence that rough grading for land development has been completed within standard tolerances in accordance with the approved plans and that all embankments and cut slopes and pad sizes are as shown on the approved plans.
C. 
Landscape Architect. The designing landscape architect shall incorporate applicable recommendations from the soils engineering reports along with appropriate measures related to soil engineering into the landscape and irrigation plans and conditional approval recommendations. The landscape architect shall also prepare plan revisions, to include securing approval from the city engineer prior to installation, and shall submit asgraded drawings incorporating all changes and/or additions made during construction. The landscape architect shall, if requested by the city engineer, prepare alternative concept contour grading plans for review and approval by the city engineer.
D. 
All groundcover shall provide one hundred percent coverage within nine months of planting, or additional landscaping shall be required in order to meet this standard.
E. 
Soil Engineer. The soil engineer is responsible for performing the preliminary soils engineering investigation and preparing the preliminary soils during grading, providing compaction inspection and testing, and preparing the final soils engineering report. The soil engineer is also responsible for reviewing and signing the grading plan insuring and assuring that they comply with the soils and geotechnical recommendations of the preliminary soils engineering report.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
A. 
Setbacks and other restrictions specified by this section are minimums and may be increased by the city engineer or by the recommendation of the civil engineer, soil engineer or engineering geologist, if necessary for safety and stability, or to prevent damage to adjacent properties from deposition or erosion, or to provide access for slope maintenance and drainage. Where zoning requirements exceed the minimums in this section, the zoning setbacks shall govern.
B. 
Retaining wall may be used to reduce the required setbacks when approved by the city engineer.
C. 
The tops and toes of slopes shall be set back from the outer boundaries of the permit area, including slope rights areas and easements, as follows:
1. 
Top of Cut Slope. Top of cut slopes shall not be made nearer to a site boundary line than one fifth of the vertical height of cut with a minimum of two feet and a maximum of ten feet, as measured horizontally.
2. 
Toe of Fill Slope. The toe of fill slopes shall be made not nearer to the site boundary line than one half the height of the slope with a minimum of two feet and a maximum of twenty feet, as measured horizontally.
D. 
Setbacks between graded slopes (cut or fill) and structures shall be provided to the satisfaction of the city engineer.
E. 
A usable side yard of at least five feet from any building wall shall be provided to the toe and top of a slope, unless waived by the city engineer.
F. 
No provision in this section shall be construed to allow less than the required setback for berms and drainage unless an approved drainage device is used to reduce these requirements.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
A. 
Cut slopes shall be no steeper than two horizontal to one vertical (2:1) unless the applicant can demonstrate to the satisfaction of the city engineer and development services director that the project would be substantially improved with steeper cut slopes.
B. 
Requests for approval of cut slopes steeper than 2:1 must be accompanied by a geotechnical report that establishes such slopes will be stable, and accompanied by a landscape architect report that establishes such slopes can be adequately landscaped. In no case shall cut slopes steeper than 1-1/2:1 be allowed under any waiver of the 2:1 standard.
C. 
The city engineer may require slopes flatter than 2:1 in order to achieve the stated design and landscaping purposes of the city.
D. 
Unless specifically approved by the city council or planning commission, no cut shall exceed a vertical height of forty feet. In approving cut slopes higher than forty feet, the following shall be considered:
1. 
The lack of feasible alternative grading designs which result in slopes of forty feet or less; and the furtherance of general plan goals and objectives by the proposed development; or
2. 
Overriding benefits to the city from the development proposal.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
A. 
Fill slopes shall be no steeper than two horizontal to one vertical (2:1), exclusive of benches and terraces. The city engineer may require slopes flatter than 2:1 in order to achieve the stated design and landscaping purposes of the city. Where a fill slope is to be located near the site boundary and the adjacent off-site property is developed, special precautions shall be incorporated in the work as the city engineer deems necessary to protect the adjoining property from damage as a result of such grading.
B. 
Unless specifically approved by the city council or planning commission, no fill shall exceed a vertical height of forty feet. In approving fill slopes higher than forty feet, the following shall be considered:
1. 
The lack of feasible alternative grading designs which result in slopes of forty feet or less; and the furtherance of general plan goals and objectives by the proposed development; or
2. 
Overriding benefits to the city from the development proposal.
C. 
Slope stability analyses shall accompany soil engineering reports for all fill slopes exceeding forty feet in height, where authorized by the city council or planning commission, regardless of the slope ratio. The soil engineer shall provide a written statement approving the slope stability. In addition, the soil engineer shall recommend alternative methods of construction or compaction requirements necessary for stability.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
All slopes thirty feet or more in vertical height shall have drainage terraces at least six feet in width established at not more than thirty foot vertical intervals on all cut or fill slopes to control surface drainage and debris. Where only one terrace is required, it shall be at mid-height. Suitable access shall be provided to permit proper cleaning and maintenance. Such drainage terraces shall be improved with a paved swale or ditch at least one foot deep, with a minimum grade of two percent and wide enough to carry the one-hundred year storm runoff arriving at the terrace.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
Unless waived by the city engineer, a compacted earthen berm shall be constructed at the top, or along the line of vertical curvature, of all slopes steeper than 5:1. The berm shall conform to the slope and shall be a minimum of one-half foot high and two feet wide. The city engineer may require larger berms if necessary to achieve the stated design purposes of the city.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
Stormwater runoff from lots or adjacent properties shall not be carried over cut or fill slopes steeper than 5:1. Such runoff shall be provided to the satisfaction of the city engineer. Surface runoff shall not be permitted to flow from one residential lot to another.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
A. 
Cut and fill slopes shall be provided with subsurface drainage as necessary for stability, and as recommended by the soil engineer and/or the engineering geologist.
B. 
All canyon fills and buttress fills shall be provided with subdrains, unless waived by the city engineer, based upon the information provided by the engineering geologist and/or the soil engineer indicating that they are not necessary and recommending against them.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
The city engineer may require public interest slopes to be rounded into existing terrain to produce a contoured and smooth transition from cut or fill faces to natural ground and abutting cut or fill surfaces. Such slopes shall be contour graded and landscaped pursuant to a landscape plan prepared by a landscape architect and approved by the city engineer. The contours of the finished slope shall approximate the natural contours to the satisfaction of the city engineer. The brows or tops of slopes may be straight to match the lot lines and facilitate placement of lot fences.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
A. 
The grading will be considered in substantial compliance if the pad elevations and slope heights shown on the approved grading plan are within plus or minus one foot of the elevations shown on the tentative map or approved conceptual grading plans.
B. 
The city engineer and the development services director have discretion to permit up to a two-foot elevation variation if they determine that the change will not adversely affect views, drainage and unusable yard areas, and the change is needed to create a better design.
