Full scale prints are now included with the drainage calculations for the Pre & Post-Development drainage areas. Ground cover and soil type has been indicated on the Existing Conditions Plan. All disturbed area on the site will be loamed and hydroseeded, as noted on the landscape plan. 16. No longer applicable. 17. All slopes are 3H:1V adjacent to the swale. 18. Test pits have been performed and are included in the drainage report appendix. No on-site storm water storage is proposed at this time. As mentioned previously, the MA DEP Stormwater policy is no longer applicable to this project. 19. If the DI structure,located in the grass swale along the southerly portion of the site becomes plugged, an emergency outlet exists through the proposed weir opening. Both openings have been covered by proposed trash racks. 20. Revised accordingly. 21. Added accordingly. 22 thru 26. No longer applicable.

Additionally,the proposed point of stormwater discharge is located on site and outside of the 100' buffer. Therefore, it is our opinion that the NIA DEP Stormwater Policy is no longer applicable to this project. As discussed with you on September 12, 1997, the stormwater runoff from the development of this lot was master planned to discharge into e cisting detention basins s no located off-site.detention These basin required on-site. were designed to include runoff from this lot. Therefore, there is no ad As discussed in the Stormwater Policy (Volume One on page 2-4, r�Protect noAct.s It is our opinion outside of the 100' buffer zone, then there is no jurisdiction unr the lW Wetlands which is outside of the 100 buffer zone. that the "new point source" is located on-site, in a proposed grass Please review the revised plans and let us know if you concur with our opinion.
