City Code Section
- Plans and specifications must be submitted in accordance with Section 24.10.070 and in addition must comply with the following:
- A. Plans must be drawn to scale upon substantial paper or cloth and must be of sufficient clarity to indicate the nature and extent of the work proposed and show in detail that they will conform to the provisions of this Title and all relevant laws, ordinances, rules, and regulations. The first sheet of each set of plans must give the location of the work and the name and address of the owner and the person by whom they were prepared.
- The plans must include the following information.
- 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 construction.
- 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, retaining 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 or trees in the adjacent rights-of-way that are within 15 feet of the property or that may be affected by the proposed grading operations.
- 7. Specifications must contain information covering construction and material requirements.
- 8. Civil engineering report. The civil engineering report, when required by the City Administrator, must 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 must include recommendations for stormwater control and disposal.
- 9. Soil (Geotechnical) engineering report. The soil engineering report, when required by the City Administrator, must include data regarding the nature, distribution, and strength of existing soils, design criteria, and conclusions and recommendations applicable to the proposed development. The report must include recommendation for subdrainage, and for groundwater control and disposal. Recommendations included in the report and approved by the City Administrator must 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 City Administrator.
- 10. Engineering geology report. The engineering geology report, when required by the City Administrator, must 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 developed.
- Recommendations included in the report and approved by the City Administrator must be incorporated in the grading plans and specifications.
- B. Issuance. Section 24.10.070 is applicable to grading permits. The City Administrator may require that:
- 1. The amount of the site exposed during any one period of time be limited; and
- 2. Grading work be scheduled to avoid weather periods or avoid critical habitat use periods for areas existing on, or adjacent to, the development site.
- Subsequent to the issuance of the grading permit, the City Administrator may require that grading operations and project designs be modified if delays occur that can result in weather generated problems not considered at the time the permit was issued.
