Dear Mr. Anen,
On behalf of the Pine Gate Renewables, LLC, we are pleased to submit the requested additional
information for your review and approval. The comments identified in the email from your
office dated September 7, 2019 and the associated responses (in blue) are listed below.
1. Please provide documentation that the individual who signed the permit application has
authority to sign on the company's behalf. This can come in the form of a signed letter from
a company executive or other official documentation from the organization.
Please see the attached documentation.
2. The stormwater report states that grading on the site will occur. However no final grading
plan was submitted. Please submit a final grading plan for the site.
C301's sheet name ahs been revised to reflect this. Grading will occur at the driveway
entrance to ensure proper installation of the driveway culvert. No other grading will occur.
3. For solar farms to be considered pervious they must meet all of the recommendations in
Chapter E-6 of the stormwater design manual. Please provide details of the solar panels and
notes on the plans to show that the design meets all of these requirements.
Acknowledged. A solar racking detail has been added to C921. The project meets the
recommendations.
