The applicant for a grading permit required by this chapter
must comply with or cause the following requirements to be met:
A. Civil
Engineer. The civil engineer who prepared the grading and paving plans
must:
1. Incorporate
the applicable recommendations from the soil engineering and geology
reports and any City Engineer approved alternative concept grading
plan into the grading plan.
2. Establish
line and grade for the grading and drainage improvements.
3. Act
as the coordinating agent in the event the need arises for liaison
between the other professionals, the contractor and the City Engineer.
4. Prepare
plan revisions, and, when work is complete, submit as-graded drawings
incorporating all changes and/or additions made during construction.
5. Prior
to the release of building permits for any given lot or lots, 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.
B. Landscape
Architect. The landscape architect who designed the landscape and
irrigation plans must:
1. Incorporate
applicable recommendations from the soils engineering reports along
with appropriate measures related to soil engineering into the landscape
and irrigation plans.
2. Prepare
plan revisions, including securing approval from the City Engineer
prior to installation.
3. Submit
as-graded drawings incorporating all changes and/or additions made
during construction.
4. If
requested by the City Engineer, prepare alternative concept contour
grading plans for review and approval by the City Engineer.
5. Design
all ground cover to provide 100% coverage within nine months after
planting, or provide additional landscaping to meet this standard.
C. Soil
Engineer. The soil engineer who prepares the soil engineering report(s)
required by this chapter must
1. Perform
the preliminary soils engineering investigation;
2. Prepare
the preliminary soils engineering report;
3. Determine
the suitability of soils during grading;
4. Provide
preliminary pavement recommendations;
5. Provide
compaction inspection and testing;
6. Prepare
the final soils engineering report;
7. Sign
the grading plan to certify that the grading plan complies with the
soils and geotechnical recommendations of the preliminary soils engineering
report.
(Ord. 564 § 3, 2019)
All slopes exceeding 40 feet in vertical height must establish
drainage terraces at least six feet wide at not more than 30-foot
vertical intervals on all cut or fill slopes to control surface drainage
and debris. Where only one terrace is required, it must be at mid-height.
Access must be provided to permit proper cleaning and maintenance.
Drainage terraces must 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 100-year storm runoff arriving at the terrace.
(Ord. 564 § 3, 2019)
Unless waived by the City Engineer, a compacted earthen berm
must be constructed at the top, or along the line of vertical curvature,
of all slopes steeper than 5:1. The berm must conform to the slope
and 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. 564 § 3, 2019)
Stormwater runoff from lots or adjacent properties must not
be carried over cut or fill slopes steeper than 5:1. Such runoff must
be addressed as required by the City's design and development
standards. Surface runoff must not be permitted to flow from one residential
lot to another without approval from the Director.
