(A) Permit application. To obtain a permit, the applicant shall first file an application on a form furnished by the city for that purpose. Every such application shall:
(1) Identify and describe the work to be covered by the permit for which application is made;
(2) Describe the land on which the proposed work is to be done by legal description, street address or similar description that will readily identify and definitely locate the proposed building or work;
(3) Indicate the purpose of the proposed work;
(4) Be accompanied by plans, diagrams, computations and specifications and other data as required in division (C) below;
(5) State the valuation of the work;
(6) Create a land disturbance plan as required by division (C) below;
(7) Be signed by the permittee or authorized agent;
(8) Give such other data and information as may be required by the city; and
(9) Approximate start date and anticipated date of completion.
(B) Financial security.
(1) Security required. The applicant shall provide the city with financial security to ensure the performance of the applicant’s obligation pursuant to this chapter. The financial security may be in the form of a bond, letter of credit, escrow deposit or cash. The financial security must be provided to the city upon the submittal of the permit application. The city may use the financial security to assure that the work is completed in accordance with the submitted plans and specifications and the provisions of this chapter. The financial security may also be used by the city to eliminate any hazardous conditions associated with the work and to repair any damage to public property or infrastructure that is caused by the work. Applicants who are applying for land disturbance permit for projects that consist of one lot with one single-family home are exempt from the financial security requirement of this chapter, so long as the city determines that there is no potential for environmental degradation.
(2) Amount of security. The amount of security shall be 125% of the estimated cost to accomplish compliance with the approved land disturbance permit or $2,000, whichever is greater, in addition to any other security performance required by any other regulations in this code. The estimated cost shall be subject to approval by the city’s Public Works Department.
(3) Reduction of financial security. If requested by the applicant, the amount of the financial security may be reduced by the city, subsequent to city inspection. The reduction will be based upon the extent to which the grading and restoration have been completed and shall consider the continued need for erosion control. At no time prior to final stabilization, shall the security be reduced to less than 10% of the total original security amount.
(4) Release of security. Any remaining amount of the financial security deposited with the city for faithful performance of the plans and specifications and any related remedial work will be released after the completion and inspection of all such measures and the establishment of final stabilization, for the permitted site or common plan of development or sale.
(5) City remedy. If compliance with the approved land disturbance permit is not accomplished within the allowable time period, the city may bring the project into compliance by use of the security.
(6) Exemptions. The city shall be exempt from the requirements of this section.
(C) Land disturbance plan. Each application for a land disturbance permit shall be accompanied by copies of a land disturbance plan consisting of the following dependent upon the type and size of land disturbance activity conducted as described below:
(1) For any individual residential lots or commercial and industrial land disturbing less than one acre; and fill or excavate less than 100 cubic yards:
(a) Identification of proposed contour grading on the site at vertical intervals of not more than two feet;
(b) Drainage patterns clearly shown using arrows depicting direction of flow;
(c) A map showing the stages or limits of grading together with the existing or proposed finished elevations based on sea level readings;
(d) Identification of proposed building bench elevations;
(e) Submission of preliminary plans or program for water supply, sewage disposal, drainage and flood control;
(f) Soil borings, if required by the City Engineer;
(g) Appropriate best management practices set forth in this chapter and the city’s Land Disturbance Plan and implementation requirements developed by the city; and
(h) Other information as required by the city based on specific project characteristics.
(2) For all subdivisions and commercial or industrial sites in which land disturbance activities will impact one or more acre; or fill or excavate over 100 cubic yards, whichever is more restrictive; or any other site if determined appropriate by the City Engineer due to potential impacts to wetlands or sensitive receiving waters.
(a) Grading plan. A grading plan shall be provided that clearly indicates the proposed land disturbance activities. Both existing and proposed topography shall be shown and have a maximum contour interval of two feet. Drainage patterns shall be clearly shown using arrows depicting direction of flow. Other information shall be shown as required by the city based on specific project characteristics.
(b) Phasing plan. A phasing plan shall be provided that clearly indicates the areas in the order they are to be disturbed and restored. The phasing plan shall consider minimization of area and duration of exposed soil and unstable conditions, minimization of the disturbance of natural soil cover and vegetation, erosion and sediment control measure installation, weather conditions and the schedule for temporary and permanent restoration. The area and duration of each phase shall be indicated on the plan.
(c) Pond detail sheet. A pond detail sheet shall be provided for each proposed storm water pond that shows detailed pond design including normal water level, high water level, aquatic bench, maintenance bench, outlet structures, emergency overflow locations and other project specific data required by the city.
(d) Standard detail sheet. A standard detail sheet shall be provided that consists of applicable construction details for approved erosion and sediment control measures as developed by the city. Other techniques may be used upon prior approval by the city with details provided by the designer.
(e) Specifications. Written specifi- cations for land disturbance activities such as product descriptions, installation and maintenance procedures required by the applicant to carry out the project in accordance with this chapter.
(f) Storm Water Pollution Prevention Plan (SWPPP) as required under the National Pollution Discharge Elimination System (NPDES) storm water permit issued by the MPCA.
1. General. The SWPPP shall consist of three components:
a. A temporary erosion and sediment control plan;
b. A permanent erosion and sediment control plan; and
c. A narrative.
2. Temporary erosion and sediment control plan. Shall be provided that indicates the location of perimeter controls, construction fence, temporary sedimentation basins, inlet protection, areas to be seeded, areas to be mulched or blanketed, location of construction waste control (dumpsters, chemical storage, concrete washout, portable restroom facilities and the like) and all other required temporary erosion and sediment control measures as described in the city’s land disturbance and implementation requirements. This plan shall also indicate staging of temporary erosion control measures.
3. Permanent erosion and sediment control plan. Shall be provided that indicates areas to be seeded and sodded, sediment ponds, storm sewer systems and all other required permanent erosion and sediment control measures. Permanent storm water pollution controls including, but not limited to, ponds, vegetated buffers and structural measures shall be designed and constructed in accordance with other chapters of the city code and requirements of other agencies having jurisdiction.
4. Narrative. Shall be provided that describes, at a minimum, the nature of construction activity, person(s) responsible for inspection and maintenance of site erosion and sediment control including contact information, project phasing, schedules, along with the timing, installation and maintenance of erosion and sediment control measures and specifications necessary to carry out the project.
(D) NPDES permit documentation. The property owner’s agent shall apply for and be issued a National Pollution Discharge Elimination System (NPDES) general storm water permit from the Minnesota Pollution Control Agency (MPCA); and shall submit to the city a copy of the MPCA certificate of permit coverage.
