(A) By accepting the permit, the permittee automatically acknowledges and accepts that the city has the right to perform inspections of the project site.
(B) The permittee shall complete a permit application that includes a Storm Water Pollution Prevention Plan (SWPPP), Perimeter Control Plan (PCP) and Post-Construction Storm Water Pollution Prevention Plan (P-SWPPP) to be completed, sealed and signed by a licensed professional engineer and/or land surveyor as appropriate and submitted to the city representative.
(C) The plan shall include and/or address the following elements:
(1) Area vicinity map showing current zoning, adjoining property owners and street lines within 100 feet of the project boundaries all drawn at a scale not greater than one inch equals 2,000 feet;
(2) North arrow and its basis;
(3) Legend explaining symbols and abbreviations used on the plan;
(4) “Do not disturb limits” for construction activity indicated by a heavy dashed line and labeled as such;
(5) Boundary of site defined by bearings and distances and indicated by a heavy solid line;
(6) Drawing(s) at a scale not greater than one inch equals 100 feet. In the case of an unusually large development, a scale of one inch equals 200 feet may be acceptable;
(7) Acreage of the total site and acreage of the project site (if different);
(8) Directly connected impervious area (DCIA);
(9) Impervious areas as measured in square feet;
(10) Benchmark location(s), description(s) and elevation(s) at sea level;
(11) Basis of elevation datum;
(12) Name, address and telephone number of the owner, developer, permittee and project engineer;
(13) Existing and proposed topography at two-foot contour intervals;
(14) Mapping accuracy shall conform to national standards of mapping;
(15) Location of sinkholes, streams, steep slopes, known springs and watercourses;
(16) Location of any existing buildings or structures;
(17) Location of any pertinent utilities, sanitary sewers, water and storm water facilities on the property or within 50 feet of the site;
(18) Elevations, dimensions, locations and the extent of all planned grading indicated with proposed contours;
(19) A grading plan for borrow pits, quarries and material-processing facilities based on the findings of soil site investigations;
(20) Design details of temporary and permanent structural controls;
(21) Approximate location of the 100-year floodplain or a statement by a professional engineer or professional land surveyor that the site is not located in an area subject to flooding. The basis for this determination shall be shown;
(22) A detailed quantity estimate for storm water management controls and measures;
(23) Identification of perimeter controls at outfalls and areas where construction site drainage leaves the property boundary or disturbed area(s);
(24) Arrows indicating drainage flow patterns;
(25) Location, dimensions, detailed specifications and construction details of all temporary and permanent storm water quality measures;
(26) Temporary stabilization plans and sequence of implementation;
(27) Permanent stabilization plans and sequence of implementation;
(28) Anticipated construction sequence describing the relationship between implementation of storm water quality measures and stages of construction activities;
(29) Anticipated inspection and maintenance requirements for permanent and temporary measures. This shall include the expected frequency of routine inspections and maintenance activities such as removal of sediment and waste concrete;
(30) Management practices or other controls to address the following:
(a) Waste concrete management;
(b) Material delivery, handling and storage;
(c) Sanitary/septic waste management;
(d) Solid waste/trash and debris management;
(e) Vehicle and equipment cleaning, fueling and maintenance;
(f) Sensitive and vegetated area preservation;
(g) Pit and channel dewatering operations;
(h) Contaminated soil management as defined and approved by the state’s Divisions of Water and Waste Management;
(i) Hazardous materials and waste management as defined and approved by the state’s Divisions of Water and Waste Management;
(j) Pesticides, herbicides and fertilizer use; and
(k) Long-term storm water quality treatment.
(31) Per KDOW’s KYR100000, Storm Water Discharges Associated with Construction Activities, additional measures may be necessary in the plan if discharges to any of the following occur: water classifications including cold water aquatic habitats, exceptional waters, outstanding natural resource waters, and outstanding state resource waters; waters with an approved total maximum daily load; waters on the § 303(d) list of impaired waters; and
(32) Per the discretion of the city, additional measures may be required in order to adequately protect water quality and provide consistency with state and federal requirements.
(D) The permittee shall notify the city in writing of any substantial field changes made to the approved Storm Water Quality Management Plan. Changes made to the Plan must be approved by the city representative.
(E) The city shall review the SWPPP within a reasonable time frame, typically 30 calendar days, from date of submission and issue or deny the requested permit. Failure to do so will allow the person to proceed with land-disturbing activities in accordance with BMPs and the submitted SWPPP. However, the city still reserves the right to review and require changes it determines appropriate.
(F) (1) Although a separate storm water permit is not required for individual lots disturbing less than one acre within a larger permitted project, a building permit is required.
(2) All storm water management measures necessary to comply with this chapter must be implemented in accordance with the permitted plan for the larger project and adhere to the general standard or those of a common area plan.
(3) The individual permittee is responsible for the installation and maintenance of all erosion prevention and sediment control measures until the site is stabilized.
(4) The permittee, whether owning the property or acting as the representative of the property owner, shall submit to the city the following information for review and approval prior to the issuance of a building permit:
(a) Dimensions, elevations, drainage patterns and swales, and location of existing buildings and natural features that are pertinent to this chapter;
(b) Proposed drainage patterns;
(c) Location of the construction access to the site; and
(d) Location of perimeter erosion and sediment control measures prior to land disturbance.
(5) Temporary erosion prevention and sediment control measures may be removed for completion of the finish grade. Permanent stabilization to include either sod or mulched-seeding as appropriate for seasonal conditions shall be completed within 14 days prior to removal of temporary erosion prevention and sediment control measures.
