The weight of the green roof shall be considered a superimposed dead load. The design shall consider the green roof in saturated condition. (D) The construction documents required by clauses (A), (B) and (C) of this subparagraph shall not be necessary for an application for a green roof installation of a depth of four inches or less where a structural analysis of the existing building has been performed establishing that such building can, without modification, sustain the load of the green roof in a fully saturated condition in a manner that complies with the codes enumerated in subdivision (d) of this section, provided the applicant of record certifies that the construction work reflected in the application for installation complies with such codes and other requirements set forth in this section and Title 4-B and that the analyses reflected in the requirements of clauses (A), (B) and (C) of this subparagraph have been performed.

Upon completion of work, the applicant of record must submit to the Department completed Technical Reports, including final inspection, and a request for job sign-off pursuant to Administrative Code § 28-116.4.

Such maintenance plan shall be sufficient to enable the applicant for property tax abatement to maintain the green roof during the compliance period and for a minimum of three (3) years thereafter in such a way that it continuously constitutes a green roof in accordance with Title 4-B and this section. (i) The maintenance plan must require at least semi-annual maintenance inspections of the condition of the roof and plants, contingency plans for irrigation during dry or drought conditions when necessary to ensure the survival of plants, contingency plans for replanting areas where plants have died, and any other corrective measures necessary to ensure that the green roof is maintained in accordance with Title 4-B and this section. (ii) The maintenance plan must include monthly maintenance inspections to ensure that roof drains remain free of debris and in working condition. (iii) The maintenance plan must identify any problems that may be encountered, describe corrective measures for each such problem and identify when and how often such corrective measures are required in order to maintain the green roof in continuous compliance. (iv) The individual who prepared the maintenance plan must certify, either on the property tax abatement application, if such individual is a registered design professional, or in a report provided to the registered design professional filing the property tax abatement application, if such individual is a New York State licensed and registered landscape architect or a horticulturist with a degree or certificate from an accredited training institute, that the maintenance plan complies with this section and that he or she has provided the maintenance plan to the applicant for property tax abatement. Such maintenance plan must be provided to the Department upon request. (3) Application process. A registered design professional must complete the property tax abatement application. Such property tax abatement application must be accompanied by a Title 4-B certification by the property tax abatement applicant or such applicant’s representative that no construction of any required element of the green roof set forth in Title 4-B § 499-aaa(10), except § 499-aaa(10)(a), was commenced prior to August 5, 2008. (4) The completed property tax abatement application, together with the Technical Reports and request for job sign-off, must be filed with the Department by March 15 in order for the property tax abatement to take effect on July 1 of the same calendar year. If a property tax abatement application is filed after March 15, the property tax abatement to which such application relates shall not take effect until July 1 of the following calendar year. (5) Upon receipt and acceptance of the completed property tax abatement application and all applicable fees, the Department shall forward any required documents to the Department of Finance for review and the issuance of the tax abatement. (6) Filing date. The date of filing of the property tax abatement application shall be the date of submission of job sign-off documents and the application for property tax abatement. (g) Compliance period. (1) The applicant for property tax abatement must allow all registered design professionals, landscape architects and horticulturists involved in the installation and maintenance of the green roof and the Department to have access to the green roof and any related structures and equipment for inspection thereof at any time during the compliance period upon reasonable notice. (2) Pursuant to Title 4-B § 499-ddd(1), within the fifteen (15) calendar days prior to the last day of the compliance period, the applicant of record, landscape architect or other registered design professional must inspect the green roof, including without limitation its vegetation layer, to certify its continuing compliance with Title 4-B, this section and applicable provisions of law and rules, including but not limited to the codes enumerated in subdivision (d) of this section. Such inspecting professional must prepare an inspection report and retain such report for six years. Such report must be made available to the Department upon request. If the inspecting professional finds that the green roof is not in compliance with Title 4-B, such inspecting professional must notify the Department in a form and manner prescribed by the Department. (h) Revocation. (1) Should the Department have reason to believe at any time during the compliance period that a condition described in Title 4-B § 499-eee(1) exists, the Department shall inspect or otherwise investigate the condition. If the findings of such inspection or investigation indicate that a condition described in Title 4-B § 499-eee(1) exists, the applicant for property tax abatement must pay the inspection and investigation expenses of the Department. The Department shall notify the applicant for property tax abatement of any findings that indicate that a condition described in Title 4-B § 499-eee(1) exists and provide such applicant with an opportunity to dispute the findings. (2) No later than the ninetieth day after the last day of the compliance period, the Department shall notify the Department of Finance of any findings of noncompliance and shall identify the period of noncompliance. (3) The Department may declare an applicant for property tax abatement ineligible for future tax abatements in accordance with Title 4-B § 499-eee(4). (i) Notification of the New York State Department of Education. In accordance with Title 4-B § 499-fff(3), should the Department determine that any registered design professional or landscape architect involved in the installation and maintenance of the green roof engaged in professional misconduct in making certifications required by Title 4-B or this rule, the Department shall so notify the New York State Department of Education.
