In addition, the applicant seeks to legalize existing flush-mounted solar panels on a separate flat roof portion of the structure. Findings: The project meets all the requirements for issuance of an Administrative Permit set forth in Chapter 170 of the Southold Town Code. The issuance of an Administrative Permit allows for the operations as described in the application received on April 12, 2012. Commissioners decided that an administrative permit was appropriate in this instance because the solar panels (UniRac flush mount Solar Mounts as described in Manual#214, Pub. 040316-Iii) are flush mounted on an existing flush roof with no visual impact from the public right of way, Special Conditions: No additional work permitted beyond the scope of that outlined in the above referenced application. If the proposed activities do not meet the requirements for issuance of an Administrative Permit set forth in the Southold Town Code, a Certificate of Appropriateness will be required. This is not a determination from any other agency.

The systems that we install are always flush mounted in order to decrease their uplift capacity, in order to install a system that is not flush mounted extra engineering steps are required and the install becomes a lot more difficult. If a new homeowner were to purchase this residence and decide they did not want solar then the system is easily removed with no additional roofing required. The only step needed to be taken after the few materials are collected would be to use a sealer(like Blackjack) in order to seal the small number of penetration made to the ratter. The complete disassembly and sealing of the system would take a few hours and does not damage the existing roof.
