Home My WebLink About20061471 Ver 2_Sill Impact Acreage_20151019 Strickland, Bev From:Bullard, Teresa R SAW <Teresa.R.Bullard@usace.army.mil> Sent:Monday, October 19, 2015 7:36 AM To:Steenhuis, Joanne Subject:NPS Harkers Island Sill Impact Acreage (UNCLASSIFIED) Attachments:HINSILLSPC-01Rev4R_9-14-2015.pdf CLASSIFICATION: UNCLASSIFIED Joanne, The current impact acreage for the revised sill is ~0.70 ac. This reduction from the original impact area of 1.07 ac. was due to the removal of the sill tie-in on the northern section of the project. By removing this tie-in area impacts to SAV's within the area are avoided and the area protected by the sill will have increase tidal flushing allowing it to become more favoriable habit for SAV. I am in the office today, Thursday and Friday this week. I will be TDY on Tue/Wed but checking my email. Please let me know how best to proceed with submitting this for the 401 WQC. Thank you for all of your help with this.
