Collect all runoff from all BUA (proposed and/or existing and/or offsite) as the case may be, by any means including piping or swales, and direct it to the pond. B. Check the proposed pond design to make sure it meets or exceeds the minimum design criteria for surface area, volume and drawdown. IL What makes up a complete wet detention pond application package? A. . Two sets of sealed, signed & dated layout & grading plans with appropriate details. (Additional sets of plans may be requested for projects in certain counties) B. Completed application with supplement(s), SWU-101, SW401-Wet Pond, and inspection and maintenance agreements. C. Deed restriction document, if applicable (for subdivisions & projects with out parcels) D. Sealed, signed & dated calculations. E. Estimated seasonal high water table elevation at all pond locations. F. Chlorides test results must be provided if the project is within '/z mile of SR waters (Phase II). (This is only required to test out of SR water treatment requirements) III. BIMS entry (for DWQ use only) Enter & track application acknowledged date, review date, add info requested/received dates, permit issue dates, and drainage area info. Best done after the add info letter is written and before sending permit up for signature. IV. Shell documents (for DWQ use only) Permit shells: s:\wqs\stormwater\shells\highcompond s:\wqs\stormwater\shells\highsubpond s:\wqs\stormwater\shells\HDhybrid Spreadsheet: s:\wqs\stormwater\excel spreadsheets\pond VI. Review Procedure A. APPLICATION Z. 1. An original signature is required. Photocopied signatures cannot be accepted. V/2. A -completed wet detention pond supplement and a signed, dated and notarized wet 2 detention pond Inspection and Maintenance Agreement with an original signature. 3. The numbers on the supplement match up to the numbers used in the calculations and shown on the plan details. Built -upon areas are reported in square feet in Section 111.6. 5. Receiving stream name and classification. This is important because in the non -Phase It counties, a wet pond cannot be used on a project that is within'/ mile of and draining 1✓j. to SA waters. For Phase II, a wet pond is allowed within ''/z mile of SA waters. 6. Section 111.6 is filled in -cannot be left blank. One column must be filled in for each proposed wet pond. 7. If the applicant is a corporation, partnership or LLC, look it up on the Secretary of State Corporations Database. Make sure corporation is spelled correctly (capitalization and punctuation matter) and that the person signing the application is at least a vice- president in the corporation, a General Partner -in the partnership, a�member ,`;;_ :. ,..member -managed !LLC,- or the•, manager 'of a ' manages=managed' LLC' Need documentation to support if the Articles of Incorporation do not list the members or managers of the LLC. If an agent signs, then a letter of authorization is needed from the president, vice president, general partner, member ormanager. ' . ' • ` 8�/ For subdivided projects; a signed and notarized deed. restriction statement must be provided. i5 Wet Detention Pond, cont. B. CALCULATIONS 1. The orifice is sized based on drawing down the calculated minimum volume in 2-5 days. The average head to use in the orifice equation is approximately one-third of the distance between the permanent pool elevation (PPE) and the elevation of the next available outlet above the permanent pool. The elevation of the next available outlet must be either the elevation where the minimum volume is provided, or it can be higher. The temporary pool elevation (TPE) to report on the supplement will be the elevation of the next available outlet above the PPE. The temporary pool volume (TPV) to report on the supplement is the volume between the specified PPE and the TPE. 2. For Phase II projects that are within'/ mile of and draining to SR waters, the difference in runoff from the predevelopment and post -development conditions for the 1 year 24 hour storm must be controlled and treated. 3. For Phase II projects, the discharge rate leaving the pond can be no more than the pre -development discharge rate for the 1 year 24 hour storm. 4. For Phase II projects draining to SA water, no discharge to surface waters may occur from wet ponds. The discharge leaving the orifice must be effectively infiltrated prior to reaching surface waters. 5. The average pond depth is the permanent pool volume divided by the permanent pool surface area. The result must be between 3 ft. and 7.5 ft. Parts of the pond can be deeper than 7.5 ft., but in no case can any part of the pond be less than 3 ft deep. 6. If the 85% TSS chart is used a 30' vegetated filter must be provided at the outlet of the pond. If the 90% TSS chart is used, no filter is required. 7. Use the correct SA/DA TSS chart from the BMP Manual noting that there are different charts for different areas of the State. 8. Required surface area at permanent pool. 9. Provided surface area at permanent pool (Based on pond dimensions) 10. Required volume calculation based on 1.5" storm for Phase II projects* and 1" storm for all others projects. *unless the project is Phase 11 and within '/ mile of and draining to SR waters then the volume calculation must be based on difference between the pre and post development conditions for the 1-yr 24-hr storm. 11. Table of elevations, areas, incremental volumes and accumulated volumes for overall pond and for forebay, to verify volumes provided. 12. Forebay designed to hold 20% of the permanent pool volume. (Range of 18%-22% OK.) 13. Non -erosive flow for 10 yr. storm in the vegetated filter, if using 85% TSS. 14. The seasonal high water table must be at or below the proposed permanent pool elevation to assure that the necessary volume will be available above the permanent pool. 15. Rounding numbers off during the calculation process can result in deficiAncies. Do not round the numbers until you get to the final result. 16. An additional one foot must be excavated below the bottom elevation of the pond. The 1 foot sediment accumulation depth is not included in the average'depth calculation. 4 le- S� A�� °'�f �G lGs �or Cc�lcs Wet Detention Pond, cont. C. PLANS- Due to storage space constraints, plan sheets should be kept to a minimum. For small commercial single wet pond projects, the plan set could consist of only 2 or 3 sheets, layout, grading and details. For larger projects, show as much information as possible on as //'few sheets as possible, without cluttering them up. Development/Project Name V �1. ✓/2. Engineer name and firm. ✓✓Z3.

The pond must have a minimum 1.5:1 length to width ratio and a minimum 3:1 flow path length. Artificial "baffles" of timber, vinyl, or earth can be used to create a longer flow path. The top elevation of the baffle should be set at the temporary pool elevation or niynci . 26. A Vegetation plan is specified for the pond, including slopes. Wetlands species are sted for planting on the 10:1 shelf. Weeping Love Grass is not suitable as a permanent 2 egetated cover for pond slopes. 27. All roof drainage must be directed to the pond. Show the roof drain collection lines on the plan. This is necessary for projects where the buildings back up the property lines where roof drainage may leave the site prior to going through the pond. — UvH c, vciuce d � W '"AMC, am--J E'-6°ho'1S —• �l�vr�,'Uns �,a( stid,� �f�s an }��� d�a�cl � wb'.r el. ��� �y °°"�a=--a('.
