1. General vicinity of the proposed site.
2. Property limits and accurate contours of existing ground and details
of terrain and area drainage for the site and surrounding area.
3. Limiting dimensions, elevations, or finish contours to be
achieved by the grading and the proposed drainage channels and related
4. Detailed schedule of when each portion of the site is to be graded;
how long the soil is to be exposed; and when the area is to be covered with
buildings, paving, new vegetation or temporary erosion control measures.
5. Detailed plans of all surface and subsurface drainage devices,
walls, cribbing, dams, and other protective devices to be constructed with, or
as a part of, the proposed work together with a map showing the drainage area
and the estimated runoff of the area served by any drains.
6. Location of any buildings or structures on the property where the
work is to be performed and the location of any buildings or structures on
land of adjacent owners which are within 15 feet of the property or which may
be affected by the proposed grading operations.
7. Specifications shall contain information covering construction
and material requirements.
8. Civil engineering report. The civil engineering report, when
required by the Director, shall include hydrological calculations of runoff
and the existing or required safe storm drainage capacity outlet of channels
both on site and off site, and 1 in 100 year flood elevations for any adjacent
watercourse. The report shall include recommendations for stormwater control
9. Soil (Geotechnical) engineering report. The soil engineering
report, when required by the Director, shall include data regarding the
nature, distribution, and strength of existing soils, design criteria, and
conclusions and recommendations applicable to the proposed development. The
report shall include recommendation for subdrainage, and for groundwater
control and disposal. Recommendations included in the report and approved by
the Director shall be incorporated in the plans and specifications. For single
family residences, a surface reconnaissance and stability questionnaire may be
substituted for a formal soils report at the discretion of the Director.
10. Engineering geology report. The engineering geology report, when
required by the Director, shall include an adequate description of the geology
of the site, and conclusions and recommendations regarding the effect of
geologic conditions on the proposed development and site(s) to be
Recommendations included in the report and approved by the Director shall
be incorporated in the grading plans and specifications.
B. Issuance. Section 24.10.070 is applicable to grading permits. The
Director may require that:
Subsequent to the issuance of the grading permit, the Director may require
that grading operations and project designs be modified if delays occur which
can result in weather generated problems not considered at the time the permit
