Conn. Gen. Stat. § 8-13t

(b) The regulations of an incentive housing zone may require the applicant for approval of an incentive housing development to pay the cost of reasonable consulting fees for peer review of the technical aspects of the application for the benefit of the zoning commission. Such fees shall be accounted for separately by the municipality from other moneys and used only for expenses associated with the technical review of the application by consultants who are not otherwise salaried employees of the municipality or the zoning commission. Any amount in the account remaining after payment of all expenses for technical review, including any interest accrued, shall be returned to the applicant not later than forty-five days after the completion of the technical review.

(c) The regulations of the incentive housing zone may provide for the referral of a site plan or subdivision application to other agencies, boards or commissions of the municipality for comment. If a site plan or subdivision application is referred to another agency, board or commission, such agency, board or commission shall provide any comments within the time period contained in section 8-7d that is applicable to such application. The provisions of this section shall not be construed to affect any other referral required by the general statutes.

(d) An incentive housing development shall be approved by the zoning commission subject only to conditions that are necessary to (1) ensure substantial compliance of the proposed development with the requirements of the incentive housing zone regulations, design standards and, if applicable, subdivision regulations; or (2) mitigate any extraordinary adverse impacts of the development on nearby properties. An application may be denied only on the grounds: (A) The development does not meet the requirements set forth in the incentive housing zone regulations; (B) the applicant failed to submit information and fees required by the regulations and necessary for an adequate and timely review of the design of the development or potential development impacts; or (C) it is not possible to adequately mitigate significant adverse project impacts on nearby properties by means of conditions acceptable to the applicant.

(e) The duration and renewal of an approval of an incentive housing development shall be governed by subsection (i) of section 8-3 , subsection (j) of section 8-3 , section 8-26c or section 8-26g , as applicable. The time to complete the work approved shall be extended (1) by the time required to adjudicate to final judgment any appeal from a decision of the commission on an incentive housing development site plan or subdivision plan or any required coordinate permit; (2) by the zoning commission if the applicant is actively pursuing other permits needed for the development; (3) if there is other good cause for the failure to complete such work; or (4) as provided in an approval for a multiphase development.

(f) An applicant for approval of an incentive housing development within an approved incentive housing zone may not make such an application utilizing the provisions of section 8-30g .

(g) Approval of or amendment to regulations or design standards for an incentive housing zone or subzone, or site plan or subdivision approval of an incentive housing development, may be appealed to the Superior Court pursuant to the provisions of section 8-8 or 8-28 .
