In the event that a development adjoins or includes existing streets that do not conform to widths as shown on the adopted Master Plan and/or Official Map or the street width requirements of this Ordinance, additional land along either or both sides of said street, sufficient to conform to the right-of-way requirements, shall be dedicated for the location, installation, repair and maintenance of streets, drainage facilities, utilities and other facilities customarily located on street rights-of-way. The necessary deeds of ownership shall be furnished, and the dedication shall be expressed as follows: "Street right-of-way granted permitting the entrance upon these lands for the purposes provided for and expressed in the Land Development Ordinance of the Township." This statement shall in no way reduce the developer's responsibility to provide, install, repair or maintain the facilities in the area dedicated by ordinance and/or as shown on the plan and/or as provided for by any maintenance or performance guarantees. If the development is along one (1) side only, one-half (1/2) of the required extra width shall be dedicated. Additionally, that portion of the existing street or road adjoining or included within a site plan or major subdivision shall be improved, including excavation, grading, base courses and surfacing in accordance with the road improvement standards of this Ordinance.
