Preliminary grading plans provide for review and determination of grading permit requirements prior to approval of final plans and issuance of a grading permit. Precise design at this stage is not required. The plans shall be clearly and legibly drawn and entitled "Preliminary Grading Plan", shall contain a statement of the purpose of the proposed grading, and shall include the following:
(A) On a map of appropriate scale, but not smaller than one inch equals fifty feet (1"=50'), or as approved by the city engineer, and include all specifications:
1. A plan entitled "Preliminary Grading Plan" and the name and signature of preparer and date of preparation.
2. A vicinity sketch (not at map scale) indicating the location of the site relative to the principal roads, lakes and watercourses in the area.
3. A site plan indicating the site of the work and any proposed divisions of land.
4. The complete site boundaries and locations of any easements and rights of way traversing and adjacent to the property, appropriately labeled and dimensioned.
5. The location of all existing and proposed roads, buildings, wells, pipelines, watercourses, septic systems or areas reserved for on site sewage disposal, and other structures, facilities, and features of the site, and the location of all improvements on adjacent land within fifty feet (50') of the proposed work.
6. Location and nature of known or suspected soil or geologic hazard areas addressed in the soils or geologic report.
7. Contour lines of the existing terrain on a topographic map and proposed approximate finished grade at intervals not greater than two feet (2') vertically, or as approved by the city engineer, showing all topographic features and drainage patterns throughout the area where proposed grading is to occur. The contour lines shall be extended to a minimum of fifty feet (50') horizontally beyond the affected area, and further if needed to define intercepted drainage, and shall be extended a minimum of one hundred feet (100') horizontally outside of any future road rights of way.
8. Approximate location of cut and fill lines and the limits of grading for all the proposed grading work, including borrow and stockpile areas.
9. Location, width, direction of flow and approximate location of tops and toes of banks of any watercourse.
10. Approximate boundaries of any areas with a history of flooding or wetlands and floodplains as shown on the national insurance rate map.
11. Proposed provisions for storm drainage control and any existing or proposed flood control facilities or septic tank disposal fields or areas reserved for on site sewage disposal in the vicinity of the grading.
12. A conceptual plan for erosion and sediment control including both temporary facilities and long term site stabilization features such as drought resistant planting or seeding for the area affected by the proposed grading. This requirement may be waived by the city engineer for sites having no slopes greater than five percent (5%) unless the large size of the site, its proximity to sensitive areas or other conditions make an erosion or sediment discharge hazard possible.
13. North arrow and scale.
14. General location and character of vegetation covering the site. The approximate location of all trees which are healthy and have a circumference of twenty four inches (24") or greater measured twenty four inches (24") above the ground, or trees twenty feet (20') in height or greater. Indicate by marking with "X" those trees that are proposed to be removed.
(B) Typical cross sections (not less than 2) of all existing and proposed graded areas taken at intervals not exceeding two hundred feet (200') and at locations of maximum cuts and fills.
(C) An estimate of the quantities of excavation and fill, including quantities to be moved both on and off site.
(D) The estimated starting and completion dates of grading. (Ord. 1523, 4-11-1995)
