Stormwater Management Plan - requested 1. Fee /Application for SWM- Please contact reviewer to discuss WPO (stormwater management review) prior to submitting fee, plans, or supporting documentation. Pre - application discussion may limit need or extent of possible revisions. Certain changes will be required under SWM review, and revision prior to initial SWM application submission could save time. There is also a pending date, July 1St, when the regulations will change, and this could affect this project. B. Erosion Control Plan (WP0201400040) 1. Erosion and Sediment Control Plan Narrative, a 12 -p supporting document with Appendix should be numbered. Transfer Erosion and Sediment Control VESCH details, instructions, or measures to the plans. Unless ESC information is included on plan sheets, there is little chance it will be noticed or enacted during construction. 2. Remove or re -title sheet C -4, titled Enlarged Site Plan. Site Plans cannot be approved as part of WPO Application (Also, sect. C., item 1, below). E &S Legend, Sheet C -4A, includes culvert inlet protection (IP) and outlet protection (OP). Please show IP and OP for new 15" entrance pipe located at intersection of access drive and Lindsay Road (sheet C -413, or C -41)). 4. Sheet C -4G, Note 8: "Perform site clearing to the limits shown on the plans." Limits of disturbance are not shown; please show LOD on plans. 5. Identify off -site disposal areas. Identify construction staging area. Identify stockpile locations. 6. Show tree protection (TP) for 14" OAK, sheet C -4C, if tree is to be saved (tree shown near Alan B. Howard deed book information). Engineering Review Comments Page 2 of 3 7. Page 11 of the ESC Plan Narrative states that "Topsoil will be used to help provide a suitable growth medium for vegetation." Please identify topsoil locations, with specific details (spec 3.30, TO). Page 11 also states "Sediment shall be removed and the impoundment restored to its original dimensions when sediment has accumulated to one -half the design depth." This statement appears to relate to a sediment trap or basin not shown on plans. Please clarify. 8. Page 8 of the ESC Plan Narrative states that "During construction, the contractor will divert runoff around disturbed areas to reduce the amount of stormwater which could come into contact with exposed soils. One method of creating a diversion is by installing temporary dike /swales within the area of work." Please identify diversion dikes in plan view that correspond with stated plan to divert runoff during construction. Diverted runoff must release to a sediment trap or basin. 9. Plan views show an 11' -12' wide driveway. Narrative describes a 20 -ft driveway. Please clarify (show access drive 20 -ft wide, or revise narrative). 10. Remove sheets C -5, A -1, but include typical access road cross section elsewhere. C. Site Plan (SDP201400021) 1. Separate from WPO. Site plan may not be approved as part of a WPO. 2. ESC and a SWM Plan must be approved prior to final site plan approval (ESC Plan Review: requested changes, above). 3.
