The administrator, or the director in nonwaiver communities, shall have the option of issuing a "letter of permission" in lieu of a stormwater management certification. A letter of permission may be issued for developments that can be determined, based on review of the applicant's proposed plans, available documents, site inspection and judgment, to be limited in scope and complexity and fit the definition, for "minor development". The applicant may propose that certain submittal requirements be waived for those developments approved for processing as a letter of permission, provided that the request is in writing in advance of the submittal, and the request is approved in writing by the administrator or the director in a nonwaiver community. The applicant, or if applicable their design professionals, must affirm that all calculations are in accordance with standard engineering practice and have been checked for accuracy of calculation and are in compliance with the requirements of this title. The applicant shall remain responsible for any errors in calculation or application of engineering methodology.
A. The following are the potential modifications to submittal requirements in the form of "waiving submittal" that may be considered:
1. Supporting calculations for simple soil erosion and sediment control plans, if the development is not subject to NPDES permitting;
2. Routine backup calculations such as time of concentration, runoff curve number, and storm sewer design calculations;
3. Copies of maps such as soils maps;
4. Other supporting calculations when the results used in the design appear to the administrator to be within the norms of engineering practice.
B. The following are not eligible to be "waived for submittal":
1. Construction plans complete with all details, including soil erosion and sediment control plan must be submitted by the applicant.
2. Development securities in the amounts and forms defined in this title, record exhibits and maintenance easements may be reduced or waived if adequate other securities are required under other building permit requirements such that the administrator is reasonably assured that the intent of those provisions in this title is carried out.
C. Decisions made on behalf of the village by the administrator or director with regard to letters of permission applicability and submittal requirements are by permission to the applicant.
D. The letter of permission will serve in all respects as the stormwater management certification, with the same duration, and may be combined with a general certification for the parts of the development to which a general certification might be applicable.
E. A letter of permission cannot be used to substantively change the technical standards of this title. (Ord. G-976, 7-24-2012; Ord. G-1003, 6-11-2013)
