Before a subdivider may be released from any obligation required by his guaranty of performance, the Planning Board will require certification from the Code Enforcement Officer and whatever other agencies and departments may be involved to the effect that all improvements have been satisfactorily completed in accordance with all applicable standards and state and local codes and ordinances.
A. 
Where the Planning Board finds that extraordinary and unnecessary hardships may result from strict compliance with this Part 2 or where there are special circumstances of a particular plan, it may vary these standards so that substantial justice may be done and the public interest secured, provided that such variations will not have the effect of nullifying the intent and purpose of the Official Map, the Comprehensive Plan, or the Zoning Ordinance. This Subsection A shall not apply to the street design standards described in § 10-2.31B, the roadway construction material standards described in § 10-2.34, and the responsibility of the developer regarding streets described in § 10-2.35.
B. 
Where the Planning Board finds that, due to special circumstances of a particular plan, the provision of certain required improvements is not requisite in the interest of public health, safety, and general welfare or is inappropriate because of inadequacy or lack of connecting facilities adjacent or in proximity to the proposed subdivision, it may waive such requirements subject to appropriate conditions. This Subsection B shall not apply to the street design standards described in § 10-2.31B, the roadway construction material standards described in § 10-2.34, and the responsibility of the developer regarding streets described in § 10-2.35.
C. 
In granting variances and modifications, the Planning Board shall require such conditions as will, in its judgment, secure substantially the objectives of the requirements so varied or modified.
