§ 9 STORMWATER MANAGEMENT PLAN CHECKLIST
   STORMWATER MANAGEMENT PLAN CHECKLIST
(1) The applicant shall submit (x) copies of the Narrative Description and five (5) copies of all plans. Plans shall be a minimum of 8.5" x 11" and a maximum of 18" x 24" at a scale of 1" = 40' with a sufficient number of sheets to clearly show all of the information required. Sheets shall be numbered sequentially (e.g. sheet 1 of 3, etc.) For projects involving a Subdivision, Land Development Project, or Development Plan Review, an additional seven (7) reduced copies of the plan shall be submitted (minimum size of 8.5" X 11"; maximum size of 11" X 17").
(2) Plans shall conform to the Procedural & Technical Standards For the Practice of Land Surveying in the State of Rhode Island and Providence Plantations, as prepared by the RI Society of Professional Land Surveyors, Inc, as amended.

NARRATIVE DESCRIPTION
   Initial &date
   (staff)
   Project Description
   Brief description of the nature and purpose of the land disturbing activity and the amount of grading involved (acreage or square footage of disturbance
   Existing Site Conditions
   A description of the existing soils, topography, vegetation, and drainage
   Adjacent Areas
   Description of the watershed the site is within, and adjacent areas which might be affected by the land disturbance
   Critical Area
   Description of areas on or adjacent to the site, which may be seriously impacted by the development
   Erosion and Sediment Control Measures/Construction Site Runoff Control
   A description of the methods which will be used to control erosion and sedimentation on the site before, during, and after construction. Reference 1990 RI SEICSC Handbook (available through RI RC&D 885-1321; can refer to proposed SWMPP)
   Stormwater Management Guidelines
   Compute pre-and post-development runoff discharges using "TR 55" method    
   Adherence to Stormwater Management Regulations
   Design necessary permanent and temporary stormwater management specifications, including control structures to minimize sediment transport and flooding. Evaluate the final off-site destination of the runoff.   
 
   Computations
   Include all supporting computations, in an orderly manner, for hydrology and design structures, including all "TR 55" and other accepted methodology worksheets and computer printouts (CN number, time of concentration, storage volumes, hydrographs, etc.)   
   Maintenance 
   Include schedules of regular inspection, operation and maintenance, and authority delegations.
   Review Process
   Include a listing of all agencies currently reviewing the project and the status of these reviews.
   Water Quality Impacts
   Discuss possible pollutant sources; evaluate the impact on any water body, including groundwater aquifers, intermittent and perennial streams, ponds and wetlands; and discuss any possible measures to be used in reducing, mitigating this impact.
   Soils
   If stormwater management control measures depend on the hydrologic properties of soils, a soils report based on onsite boring logs or testhole data   
SITE PLAN
Initial &date
   (staff)
   Topography

   Soils
   Boundaries of different soil types within the watershed, including delineation of the site. (Copies of soil survey sheets with boundaries and roadways drawn on the map are sufficient).
   Watershed Patterns
   Delineate the watershed sub areas and indicate all water course flow directions including pre-and post-development conditions. Delineate all flow "TR 55", ID segments on the plan.
   Wetlands
   The delineation, if applicable, of the 100-year floodplain and any on site wetlands.
   Limits of Clearing and Grading
   Outline areas to be cleared and graded   
   Phasing
   If a project is to be phased, delineate limits of each phase (including temporary grading)
   Location of Practices
   The location of the erosion and sediment control and stormwater management practices used on the site, included within a legend, where appropriate.
   Improvements
   Any existing or proposed improvements, including location of buildings or other structures, impervious surfaces, storm drainage facilities, and all grading.
