(A) An applicant for a grading permit shall first file an application there for in writing with the Engineering Department. Every such application shall:
(1) Give the name and address of the record owner(s) of the site;
(2) Give the name and address of the grading contractor;
(3) Give the legal description and street address of the site;
(4) State the purpose of the work;
(5) Identify and describe the work to be covered by the permit for which application is made;
(6) Be accompanied by a construction schedule which will show the estimated start and finish dates for every major element of work, including any required public improvements. The builder shall submit a revised schedule monthly, or as often as deemed necessary by the Engineer. Note: If the schedule indicates that any portion of the work is to be performed between October 15 and April 15 a separate erosion and sedimentation control permit may be required;
(7) Be signed by the permittee, who shall be responsible for the correctness of the work and for requesting the inspections required in this chapter;
(8) Be accompanied by plans and specifications, including: A map showing the present elevation of the land and the proposed elevations of the land after completion of the proposed grading; a plot plan showing the location of the grading boundaries, lot lines, neighboring public ways and sufficient dimensions and other data to show the location of all work; description of the type and classification of soil in Chapter 29 of the Uniform Building Code; details and location of proposed drainage structures, piping, walls and cribbing; and such other information that the engineer may require to carry out the purpose of this chapter. All plans shall bear the name of the person responsible therefor and shall be submitted to the Engineer in duplicate. Unless otherwise approved by the Engineer, all such plans and specifications shall be prepared by a registered civil engineer. Exception: The Engineer may waive the requirement for any or all plans and specifications if the information on the application is sufficient to show that the work will conform to the provisions of this chapter. This exception shall not relieve an applicant of any duty to comply with subdivision and zoning laws and ordinances, or any other ordinances or state laws which may be applicable;
(9) Be accompanied by a preliminary soil report prepared by a registered soils engineer, which shall be based on adequate test borings or excavations. The report may be waived if the available information as to the qualities of the soil satisfies the Engineer that no preliminary analysis is necessary.
(a) If the preliminary soil report indicates the presence of critically expansive soils or other soil problems which, if not corrected, would lead to structural defects, than a soil investigation and report shall be required for each site. The soil investigation and report shall be prepared by a registered soils engineer. The report shall recommend corrective action which is likely to prevent structural damage to any structure to be constructed on the expansive soil.
(b) The soil investigation and report shall be approved if the Engineer determines that the recommended action will likely prevent structural damage to any improvement to be constructed. As a condition to the issuance of a building permit, the approved recommended action shall be incorporated in the construction of any improvement on the site.
(B) When an erosion and sedimentation control permit is required by
§ 15.28.050, the provisions of said permit shall supersede conflicting provisions of any other permit. The application shall be accompanied by plans and specifications prepared by a registered civil engineer. The plans and specifications shall describe in detail specific erosion and sedimentation prevention practices to ensure the effective control of soil losses within the tolerable limits prescribed in
§ 15.28.075. The developer shall be guided by the principles of erosion prevention described in the following subdivisions or by any other acceptable principles or practices.
(1) The erosion and sedimentation control plan should be fitted to the topography and soil class so as to create the least potential for soil loss. Maximum use shall be made of vegetation to minimize inevitable soil loss through land disturbing activity, such as:
(a) Natural vegetation should be retained wherever possible;
(b) Where inadequate natural vegetation exists, or where it becomes necessary to remove existing natural vegetation, temporary vegetation or mulching should be installed promptly to minimize inevitable soil loss and to ensure that soil losses are kept below the tolerable limits;
(c) Erosion control elements shall be implemented as soon as practical in the development process, except that the time elapsed shall not exceed 60 days after the cessation, termination or completion of grading, whichever comes first.
(2) Exposure of the soil through land disturbing activity should be held to the smallest practicable area and to the shortest practicable period of time consistent with maximum tolerable soil loss levels.
(3) Appropriate provision should be made to accommodate increased storm water runoff and consequent soil loss occasioned by changed soil and surface conditions during and after development. In addition to the use of vegetation and limitations on soil exposure as prescribed herein, such provisions may include but are not limited to:
(a) Scheduling permanent improvements such as streets, storm sewers, curb and gutters, and other features for control of storm runoff, before removing vegetative cover from the area;
(b) Installing and maintaining sediment basins, debris basins, desilting basins or silt traps to substantially reduce sediment from runoff water.
(C) Whenever an erosion and sedimentation control permit is required, a security deposit of $1,000 per acre for land within the limits of grading shall be required to guarantee that provisions of the permit are met. Any measures which are temporary and portable, such as sand bags and Visquine, may be deposited so as to not interfere with normal construction activity during dry weather. However, any necessary measures shown on the approved plan shall be in place during any storm event.
(1) If those erosion control measures shown on the plan are not in place within 24 hours of the prediction of a storm event by the U.S. Weather Service, the City Engineer may have such measures installed and charge any costs thereof against the security deposit.
(2) If any sedimentation does collect in the public right-of-way, it shall be cleaned up within 24 hours of the end of each storm event. Failure to do so may permit the City Engineer to have the street cleaned and charge any costs thereof against the security deposit.
