A. Signature, Certification Required: An erosion control plan (ECP) or stormwater pollution prevention plan (SWPPP) submitted with an application for a permit must bear the signature and certification number of an individual who has successfully completed a City approved training course and who has demonstrated competence, through education, training and knowledge of the applicable laws and regulations, in erosion and sediment.
B. Permit Issuance: The PDS shall review all submitted ECPs and issue a permit for each approved ECP.
C. Partial Approval: An ECP may be approved in whole or in part. If only part of the erosion control plan has met approval, only that section of the project for which the plan has been approved, shall be allowed to commence.
D. Nonissuance Of Permit; Notice; Appeal: If an ECP is not approved, a permit will not be issued, and the applicable construction activity will not be allowed to commence. Notice of this decision shall be sent to the applicant and a new erosion control plan will be required prior to the issuance of a permit. An applicant may appeal a decision not to approve an ECP pursuant to the provisions of section 9-14-3-2 of this chapter.
E. Information Required: ECPs shall include the following:
1. An ECP which discusses, with supporting technical documentation, the strategy of the proposed erosion control plan, and including significant details of the BMPs which will be utilized. This report shall be typed, except for computational sheets, in good technical form, on eight and one-half inch by eleven inch (81/2" x 11") paper and bound in a covered binder. Maps, diagrams and figures, shall be clearly labeled and folded to fit within the report. The report shall contain the title on the outside of the binder and include a title sheet, table of contents, list of figures and tables, and the narrative or body, in that order. The narrative shall contain an introduction, analysis and conclusion.
2. A site drawing of existing and proposed conditions, including:
a. Property boundaries and lot lines.
b. North arrow, scale and date.
c. Excavations, grades, paved areas, pond elevations, structures and utilities.
d. Drainage easements.
f. Surface water and wetlands, drainage patterns and watershed boundaries, if present.
g. Location of vegetative cover.
h. Location of BMPs.
i. Dewatering channels, basin(s), advanced treatment system (ATS) and other BMPs for dewatering.
j. Authorized nonstormwater discharge(s).
3. A topographic survey showing drainage and irrigation water conveyance systems and finished grade contours at two foot (2') intervals. Sites less than one acre, with less than two percent (2%) cross grades, may submit grade spot elevations of the property line and other required points in lieu of the topographic study.
4. Provide notification to the construction site operator(s) if the project is required to obtain coverage under the NPDES construction general permit.
5. Provide contact information for other agencies requiring notification of any activity related to the permit as applicable.
6. A description of the receiving waters.
7. A plan of new or modified drainage systems, including system dimensions.
8. All located in areas which are regulated by the Boise foothills development ordinance (title 11, chapter 11-07 of this Code) shall have all erodible soils designated and classified using the Unified Soil Classification System (USCS). An engineering geology or geotechnical report, prepared by a registered geologist or geotechnical engineer, and providing recommendations for erosion control, may be required if a determination is made that additional information is necessary to assess the ECP.
9. Location and schedule of soil disturbance.
10. A description of all applicable sediment, erosion, runoff, administrative and good housekeeping controls to be implemented.
11. A BMP inspection and maintenance schedule.
12. The final vegetation, landscape and permanent stabilization measures.
13. The name, title, address and telephone number of the landowner or owner's representative.
14. Any other information used to prepare the ECP, such as geologic reports prepared by a registered geologist, maps and geotechnical engineering reports prepared by a registered engineer, and soil surveys. Photographs should be included or cited by reference.
F. Stormwater Management Plan: If the applicant submitting an erosion control plan has an approved stormwater management plan which contains the requirements listed above, the applicant may file proof of the approved stormwater management plan in lieu of submitting a new ECP.
G. Modifications; Fee: ECPs may be modified at the permit holder's request upon an approved application for modification and payment of the applicable fee. Any modification deemed by PDS to be minor may be approved on site by an authorized enforcement agent without the need for a formal application and fee payment. The authorized enforcement agent shall document the modification on a field report or correction notice, and the approved plans, with a dated signature.
H. Order Of Revised Plan; Appeal: If an authorized enforcement agent determines the facilities or techniques of an ECP are not effective or sufficient after prior approval, and is having an impact on public property or private property not controlled by the permit holder, or is placing the City in violation of its NPDES permit, the agent may order a revised plan be submitted within a reasonable time period. If the revised plan is not acceptable or is not immediately implemented upon approval, the permit may be suspended or revoked. Any decision of the authorized enforcement agent or PDS may be appealed pursuant to section 9-14-3-2 of this chapter.
I. Emergency Control Measures: Emergency control measures may be ordered when erosion products are actually leaving the site or sediment deposition is occurring. These measures will not relieve the duty to file a revised plan if ordered. (Ord. 48-14, 12-16-2014, eff. 1-1-2015)
