CHAPTER 61 - LOT AND SITE DEVELOPMENT APPROVAL PROCEDURES

Printable Version

61.550 DRAINAGE PLAN:

A drainage plan shall be prepared to address the impact a development will have on existing drainage facilities and to provide a basis for designing the storm drainage system within the development.  The plan shall be consistent with the Rochester Stormwater Management Plan or adopted drainage or stormwater policies.

61.551

Drainage Plan Required:  A drainage plan shall accompany an application for:

1. A General Development Plan or Site Planning Permit involving an increase in impervious surface area.  The drainage plan for a General Development Plan is conceptual in nature.
2. A Preliminary Plat of land for which no Drainage Plan has been prepared.
3. The master plan of any multi‑phase development requiring only zoning certificate or conditional use approval.
4. Any lands not covered by a detailed drainage plan, including but not limited to lands subdivided through a Type I, II, or III process.
5. Other development requiring a grading plan, unless waived by the City Engineer.

61.552

Modifications:  Modifications to an approved drainage plan may be submitted along with a Land Subdivision Permit or the application for approval of any phase of a multi‑phase development.

61.553

Waiver: The requirement for a Drainage Plan may be waived by the City Engineer where the system of drainage for an area has been defined by development of surrounding property or where a plan for the entire watershed has been prepared.  In the case of the review of General Development Plans, the Zoning Administrator upon agreement by the City Engineer may allow a period of grace on the submittal of the required drainage plan.  If it will create problems, review of the General Development Plan maybe allowed to proceed prior to the drainage plan submittal, but the drainage plan shall be provided before the Planning Commission hears the application for a General Development Plan.

61.554

Contents:  Refer to the document Engineering Standards for Public Works in Conjunction with the Development of Subdivision, Commercial and Industrial Property to determine Drainage Plan requirements.

61.555

Approval: The City Engineer shall approve any drainage plan that complies with the requirements of Section 61.554 and the Site Design Standards in Chapter 64 of this ordinance.  The drainage plan shall be valid so long as development on which the plan is based is completed within three years or within the timeframe of a valid General Development Plan.  If development has not been completed within 3 years of initial approval of the drainage plan (or within the timeframe of a valid General Development Plan) or the applicant modifies the development, the City Engineer may require the plan to be modified to address changing site conditions, standards or drainage plans.
