This letter is directly responsive to comments previously submitted by Demian Sorrentino AICP, CSS of Boundaries LLC and follows the same numerical sequence as is used in that letter. Plan Comments: 1. The revised plan calls out the areas (in square feet) of wetland fill, location of sedimentation, and areas of disturbance to the Upland Review Area (U RA). 2. Features such as approximate stockpile locations and areas sedimentation have been added to the plans. 3. New topography has been added as well as proposed grading to handle storm water flows. 4. The wetlands have been re-nagged as of 10/21/2018. 5. The depicted wetland work was performed in 2003. 6. The new plans will be presented to the commission with signatures. 7. A construction sequence has been provided as well as a planting and seeding plan calling for trees, shrubs, and plugs of wetland vegetation at each wetland impact location. 8. Construction details have been provided. 317 Main Street· Norwich. CT 06360 860.892.1380 ebartlett@greensitedesignllc.com Review Comments and Recommendations: Wetland Impact Area #1 1. Green Site Design concurs. 2. The approximate limit is now shown. 3. It appears that removal of these sediments would cause undue damage to the existing, dense native vegetation. Green Site Design proposes over seeding this area with wetland seed mix. 4. A sediment trap, fed by a swale, is provided on the revised plans Wetland Impact Area #2 1. Green Site Design concurs and has flagged the wetland boundary. 2. Green Site Design concurs and notes that Lombardi will no longer import chicken manure to the site, thus removing the source of nutrients. 3. A swale leading to a sediment trap is shown on the revised plans. Wetland Impact Area #3 1. Green Site Design concurs and has re-delineated the wetland. 2. Green Site Design has shown restoration and storm water management that moves the usable area further from the wetland at this part of the site. 3. See #2 above. Wetland Impact Area #4 I. Green Site Design concurs. 2. Green Site Design concurs and notes that Lombardi will no longer import chicken manure to the site, thus removing the source of nutrients. 3. The extent of sediments goes to the limits of clearing and these sediments will be removed. 4. This area will be over seeded and planted with trees and shrubs. 5. Green Site Design concurs and has shown a sediment trap. Please note that additional areas of concern were noted during the joint field walk (Nancy Woodlock, Demian Sorrentino and Robert Russo) of October 22, 2018. They are addressed as follows: Wetland Impact Area #5: 1. Green Site shows minor regrading and seeding to re-establish vegetation within URA; narrowing width of the access drive are shown on the plans. Wetland Impact Area #6 1. Minor re-grading and seeding to establish vegetation are shown. Wetland Impact Area #7 1. Removal of equipment and materials; minor regrading and seeding to re­ establish vegetation within URA are shown. Wetland Impact Area #8 ]. The construction of a larger sediment basin with spread apron outlet is shown. Wetland Impact Area #9 I. The basin outlet will be improved to stop sediment release.
