Impact Justification and Mitigation 1. Avoidance and Minimization la Specifically describe measures taken to avoid or minimize the proposed impacts in designing project The proposed roadway alignment was carefully selected to minimize impacts to jurisdictional waters and riparian buffers A large S curve was added to the alignment to faaliate perpendicular crossings of three jurisdictional features, and the road alignment was shifted as far south as feasible to avoid impacting S1 and S2 and their buffers S1, S2, and their buffers are only minimally impacted by the proposed alignment at the extreme upslope end of the stream systems The proposed road will tie into existing roadway stubs on both ends to minimize new road construction overall lb Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques Impacts to streams within the corridor will be minimized to the extent practical throughout the construction process by avoiding stream features wherever possible Where feasible, staging and construction access will be located in upland areas throughout the corridor, and silt fencing will be installed around the permitted limits of distrubance to ensure all equipment is located within the project corridor at all times near stream areas Best Management Practices (BMP) and measures will be used to reduce stormwater impacts to receiving waters and minimze runoff from the construction sites 2.

As the Bank Sponsor for all sites, EBX attests to the fact that mitigation is available for transfer upon permit issuance at this time. Banker will notify applicant if the 40,180 Square Feet of Riparian Buffer Mitigation become considered "At Risk" of not being available prior to permit issuance. Credits are not considered secured until payment in full is received from the applicant resulting in the issuance of a and Affidavit of Sale by the bank acknowledging that the applicant has fully secured credits from the bank and the Banker has accepted full responsibility for the mitigation obligation requiring the credits /units. The Banker will issue the Affidavit of Sale within three (3) days of receipt of the Purchase Price Banker shall provide to Applicant with a copy of the Affidavit of Sale and a documented copy of the debit of credits from the Bank Official Credit Ledger(s) showing the permit number and the resource type secured by the applicant. A copy of the Affidavit of Sale, with an updated Official Credit Ledger will also be sent to regulatory agencies showing the proper documentation.
