The plan submission and review process shall be coordinated with and integrated into the Town's planning and permitting process. Following the effective date of this section, no building permit shall be issued without an approved stormwater management plan if required under this article.
(a) The owner/applicant/design engineer for any project that disturbs an acre or greater (including projects of less than one acre that are part of a common plan of development or sale that will disturb, in total one acre or more) must develop and submit a Pre-Application Stormwater Concept Plan. This should be done early in site planning process before infrastructure & lot configurations are locked down.
The Concept Plan should include:
(1) Graphic elements showing the general type, location and size of proposed stormwater BMPs that will be used to meet the requirements to manage the first one-inch of rainfall.
(2) Narrative & Computations Elements that describe:
a) Site design incentives
b) Conceptual or preliminary computations that show the Target Treatment Volume and the Stormwater BMP types and sizing necessary to control it.
c) A project specific version of the Design Compliance Spreadsheet shall be included in the submittal.
(3) Pre-Application Meeting shall be held for a preliminary review of the concept Plan to discuss site compliance issues, allow for constructive interaction and head off any issues that would cause delays in the approval process.
(4) Review and approval of the Concept plan: Coordinate with other departments & Agency reviews. This review is to ensure there is enough information to ensure complete and compliant Final Storm Water Management Plan. Engineering details and final computations are not expected at this stage. This review will also allow the Town to review the project for compliance with Zoning, Building and other codes, access to utilities, check potential traffic issues and coordination with other agencies.
(5) Revise Concept Plan in Response to Comments
(6) Develop the Final Stormwater Management Plan
(7) Review & Approval of Final Stormwater Management Plan. Coordinate with other Departments & Agency reviews
(8) Revise Final plan in response to comments. Issue permit when all comments have been addressed and approved.
(9) Inspection and Verification of post-Construction Stormwater BMPs. Post- construction BMPs shall be inspected at critical stages during construction and a final inspection shall be done to verify that the BMP is installed in accordance with the approved plan and/or any approved field changes.
(10) Submit As-Builts. As-Built survey should confirm Placement of BMP within easements, proper sizing, dimensions and materials. Elevations of inlets, outlets, risers, embankments, etc. Vegetation cover must be established and conform with the planting plan.
