A. 
The Township Committee may adopt, pursuant to the provisions of Section 23 of P.L. 1975, c. 291 (N.J.S.A. 40:55D-32), a document known as the "Official Map of the Township of Riverside."
B. 
The Official Map shall be deemed conclusive with respect to the location and width of streets and public drainageways and the location and extent of flood-control basins and public areas, whether or not such streets, ways, basins or areas are improved or unimproved or are in actual physical existence. Upon receiving an application for development, the Township may reserve for future use the aforesaid streets, ways, basins and areas in the manner provided by applicable laws of the State of New Jersey and the Code of the Township of Riverside.
C. 
Issuance of permits for buildings or structures. For purposes of preserving the integrity of the Official Map, no permit shall be issued for any building or structure in the bed of any street or public drainageway, flood-control basin or public area as shown on the Official Map or shown on a plat filed pursuant to this chapter before adoption of the Official Map, except as provided herein. Whenever one or more parcels of land upon which is located the bed of such mapped street or public drainageway, flood-control basin or public area reserved pursuant to this section cannot yield a reasonable return to the owner unless a building permit is granted, the Joint Land Use Planning Board, acting as the Board of Adjustment may, in a specific case, by an affirmative vote of a majority of the full authorized membership of the Board, direct the issuance of a permit for a building or structure in the bed of such mapped street, public drainageway, flood-control basin public area reserved pursuant to this section, which will, as little as practicable, increase the cost of opening such street or tend to cause a minimum change to the Official Map, and the Board shall impose reasonable requirements as a condition of granting the permit so as to promote the health, morals, safety and general welfare of the public.
D. 
Building lot to abut street. No lot shall be created by approval of a subdivision application and no permit for the erection of a building or structure shall be issued unless the lot abuts a street giving access to such proposed building or structure. Such street shall have been duly placed on the Official Map or shall be an existing state, county or municipal street or highway or a street shown upon a plat approved by the Joint Land Use Planning Board or a street on a plat duly filed in the office of the County Clerk of Burlington County prior to the passage of this chapter or its predecessor or any prior law which required prior approval of plats by the governing body or other authorized body. Before any such permit shall be issued, such street shall have been certified to be suitably improved to the satisfaction of the governing body, or such suitable improvement shall have been assured by means of a performance guaranty in accordance with standards and specifications for road improvements approved by the governing body as adequate with respect to the public health, safety and general welfare of the special circumstances of the particular street.
E. 
Variances. Where the enforcement of Subsection D hereof would entail practical difficulty or unnecessary hardship or where the circumstances of the case do not require the building or structure to be related to a street, the Joint Land Use Planning Board, sitting as the Board of Adjustment, may, upon application or appeal, vary the application of Subsection D hereof and direct the issuance of a permit, subject to conditions that will provide adequate access for firefighting, ambulance and other emergency vehicles necessary for the protection of health and safety and that will protect any future street layout shown on the Official Map or a general circulation plan element of the Municipal Master Plan. The Joint Land Use Planning Board sitting as the Zoning Board of Adjustment may not grant relief from street improvement requirements for lots yet to be created as a result of subdivision approval.
