The Site Map and Grading Plan (also referred to, collectively, as "grading plan") shall be prepared and signed by an individual licensed or registered by the state of California to perform such grading design and shall contain all the following information.
(a) Existing and proposed topography of the site taken at a contour interval sufficiently detailed to define the topography over the entire site. Ninety percent of the contours shall be plotted within one contour interval of the true location.
(b) Two contour intervals that extend a minimum of 100 feet off-site, or sufficient to show on- and off-site drainage.
(c) The property lines of the site shown in true location with respect to the plan's topographic information.
(d) Location and graphic representation of all existing and proposed natural and manmade drainage facilities.
(e) 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 drain.
(f) Location and graphic representation of proposed excavations and fills, of on-site storage of soil and other earth material, and of on-site disposal.
(g) Location of existing vegetation types and the location and type of vegetation to be left undisturbed, including the location, species, size, and dripline area of all trees (including public trees within 30 feet of the site and trees on neighboring properties that overhang the site).
(h) Location of proposed final surface runoff, erosion, and sediment control measures.
(i) Quantity of soil or earth material in tons and cubic yards to be excavated, filled, stored, or otherwise utilized on-site.
(j) Outline of the methods to be used in clearing vegetation, and in storing and disposing of the cleared vegetative matter.
(k) Proposed sequence and schedule of excavation, filling, and other land-disturbing and filling activities, and soil or earth material storage and disposal.
(l) 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 fifteen feet of the property or which may be affected by the proposed grading operations.
(m) Information covering construction and material requirements and specifications.
(n) Such further applicable plans or drawings as the building official or city engineer may require in order to carry out the purposes of this chapter.
The building official or city engineer may waive any of the requirements of this section if he/she finds that the information on the application is sufficient to show that the work will conform to the requirements of this chapter.
