Rear lots, as defined in § 219-3 of these regulations, may be permitted in R-40, RU-40, R-80 and RU-80 Zoning Districts subject to the following conditions:
A. 
The applicant shall prove to the satisfaction of the Commission that the land characteristics and physical site conditions make such rear lot development necessary, practical, reasonable, and desirable and that such rear lot development will be in harmony with the purposes and intent of the Town Plan and will comply with all applicable laws, ordinances, regulations and codes;
B. 
Such rear lots shall be used only for single-family dwellings;
C. 
The accessway to each rear lot shall be at least 25 feet in width over its entire length;
D. 
The area of such accessway shall not be included in the minimum required area of the lot and shall be deeded in fee with the lot to be served; easements or rights-of-way are not permitted;
E. 
The accessway shall extend to an improved street or to a private road in an approved subdivision;
F. 
The grade of the accessway shall not exceed 5% within 50 feet of its intersection with an improved street or road.
G. 
The length of such accessway shall not be unreasonable or unsafe as determined by the Commission.
H. 
No more than two access strips shall be located within 300 feet on the same side of the street when measured along the street line;
I. 
The required lot and yard requirements for rear lots shall be 25% greater than those specified for the zone; and
J. 
The Commission shall determine which lot line shall be construed to be the front lot line, which designation shall be clearly specified on the subdivision map.
As authorized by the Old Lyme Zoning Regulations, the Planning Commission may, in considering an application for special exception under the provisions of planned residential cluster development (PRCD), approve an application which would ordinarily be in conflict with certain provisions of these subdivision regulations. Such approval of a PRCD application shall be based on the Planning Commission's determination that the PRCD development more fully meets the objectives set forth in the Zoning Regulations for planned residential cluster development than if all provisions of the subdivision regulations were to be complied with in full. In particular, and as an example, the Commission may approve minimum lot sizes and other design requirements consistent with the Zoning Regulations despite conflicting provisions concerning rear lots as set forth in these regulations.
A nonresidential subdivision shall be subject to all other requirements of these regulations. In addition, the applicant shall demonstrate to the satisfaction of the Commission that the following requirements are met:
A. 
Streets. Street rights-of-way and pavement shall be adequate to accommodate the type and volume of traffic anticipated to be generated thereupon, and special requirements may be imposed by the Town with respect to street, curb, gutter, and sidewalk design and construction.
B. 
Utilities and drainage. Special requirements may be imposed by the Town with respect to the installation of public utilities, including water, sewer and stormwater drainage.
C. 
Extension of streets. Streets carrying nonresidential traffic, especially truck traffic, shall not normally be extended to the boundaries of adjacent existing or potential residential areas.
