(Ord. 1751-2024)
It will be the responsibility of the project site owner, or owner designee, to complete a general permit application and ensure that a sufficient construction plan is completed and submitted to City of Angola. It will be the responsibility of the project site owner to ensure compliance with this chapter during the construction activity and implementation of the construction plan, and to notify the City of Angola with a sufficient notice of termination letter upon completion of the project and stabilization of the site. However, all persons engaging in construction and land-disturbing activities on a permitted project site meeting the applicability requirements must comply with the requirements of this chapter.
(A) 
No construction activity within city limits and no land disturbance started for any construction in a development, as defined in AMC § 13.15.030, until the plans required by this chapter for such construction have been accepted in writing by the City of Angola.
(B) 
All permit applications shall follow the requirements and procedures in this section and in the City of Angola Stormwater Technical Standards Manual to obtain a site improvement permit by the City of Angola.
(C) 
Submittal for Stormwater Management Approval. The project site owner shall apply for a site improvement permit to the City of Angola prior to the initiation of any land-disturbing activities. The application will include the following:
(1) 
Completed general permit application.
(2) 
Construction plans, drainage information, and all other materials for the appropriate class of site improvement permit as outlined in AMC § 13.15.330.
(3) 
All other submittal requirements as outlined in AMC § 13.15.330.
(D) 
In the event that a project site is determined to impact or discharge to a sensitive area, be located in an impact drainage area, or determined to be a priority site for construction site inspections, the City of Angola may require more stringent stormwater quantity and quality measures than detailed in this chapter, the Stormwater Technical Standards Manual, or the Indiana Stormwater Quality Manual.
(1) 
Sensitive areas include highly erodible soils, wetlands, threatened or endangered species habitat, outstanding waters, impaired waters, recreational waters, and surface drinking water sources. A listing of highly erodible soils, outstanding water, impaired water, recreation water and surface drinking water sources can be found in the Stormwater Technical Standards Manual. If wetlands are suspected on a site, a wetland delineation should be completed in accordance with the methodology established by the U.S. Army Corps of Engineers (COE). Special terms and conditions for development determined to impact or discharge to any sensitive area shall be included in the site improvement permit.
(2) 
Priority sites may be based on the nature and extent of the construction activity, topography, threat to the degradation of water quality, characteristics of soils, complaints, and other factors as determined by MS4 priorities.
(E) 
Plan Review. After the City of Angola receives the application, the appropriate site improvement permit class will be determined. If the project is determined to be a Class V, a preliminary determination will be made whether the application is substantially complete within 10 days (for projects at least one acre but less than five acres) or within 14 days (for projects greater than or equal to five acres). If the application is deemed insufficient, additional information will be requested by the City of Angola. Once the application is deemed sufficient, and for all other permit classes, the following actions will take place for review of the permit application:
(1) 
Review will be conducted by the City of Angola and/or its plan review consultant(s). Comments and deficiencies will be provided to the applicant. Once all comments have been addressed and review completed, the City of Angola will either accept the project or request modifications. Once all modifications have been made, if required, the City of Angola will issue a site improvement permit.
(2) 
For Class V projects, the applicant may not submit the NOI to IDEM or commence land-disturbing activities until the site improvement permit is issued. The initiation of construction activity prior to issuance of the site improvement permit is a violation and subject to enforcement action. Upon submittal of the NOI, the applicant shall submit the IDEM Notice of Sufficiency (NOS) to the City of Angola and notify the City of Angola of the start date for construction at least 48 hours in advance of construction.
