H. 
To provide every effort to protect natural and cultural resources from disturbance, including steep slopes, wetlands and wetlands margins, floodplains and floodways, riparian buffers, woodlands, hedgerows, specimen vegetation, groundwater recharge areas, and historic resources as defined in this chapter.
I. 
To allow innovative, quality subdivision design.
J. 
To allow for flexibility in subdivision design.
A. 
Subdivision control. No subdivision of a lot, tract, or parcel of land shall be affected, and no street, sanitary sewer, storm drain, water main, or other facility in connection therewith shall be laid out, constructed, opened or dedicated for public use or travel, or for the common usage of the occupants of buildings abutting thereon, except in strict accordance with the provisions of this chapter.
B. 
Land development control. For all activities defined as land development under Article II, there shall be no excavating, filling or grading of the soil, and no construction, demolition, or installation which directly or indirectly disturbs the soil, except in the process of gardening or farming operations. Activities defined as land development under Article II shall not be affected, nor shall any structure or building, whether prefabricated, precut, preassembled, or otherwise be erected or placed on any lot, tract, or parcel of land, except in strict accordance with the provisions of this chapter.
C. 
Sale of lots, issuance of construction or building permits, or erection of buildings or on-site improvements. In a subdivision, no lot may be used or sold, no construction or building permit may be issued, and no building or other structure may be erected, unless and until:
(1) 
A plan for such subdivision shall have been approved and fully recorded;
(2) 
A grading plan, including a complete conservation plan for erosion and sediment control, has been duly approved;
(3) 
Until either the required public improvements in connection therewith from the lot or building to an existing improved street, or otherwise, shall have been constructed; or
(4) 
The Township has been assured, by means of a proper completion guaranty in the form of an acceptable bond or deposit of funds or securities in escrow sufficient to cover the cost of all required public and on-site improvements, as estimated may be established by the Township Engineer, or authorized representative, that such public and on-site improvements will subsequently be installed by the subdivider or owner of the property.
A. 
A subdivision or land development shall be in conformity with this chapter and all standards and specifications adopted as part of this chapter.
B. 
In the interpretation and application of the provisions of this chapter, the said provisions shall be held to be minimum requirements for the promotion and protection of the public health, safety, and welfare. Where the provisions of this chapter impose greater restrictions than those of any statute, or other ordinance or regulation, the provisions of this chapter shall prevail.
Should any section or provision of this chapter be declared by a court of competent jurisdiction to be unconstitutional, illegal, or invalid, such decision shall not affect the validity of this chapter as a whole or any other part thereof.
The Board of Supervisors shall have jurisdiction and control of subdivision and land development within the Township. To ensure that the actions of the Board of Supervisors in administering this chapter may be correlated with all relevant data and procedures, the Board hereby designates the Township Planning Commission as the agency of the Board for the following purposes:
A. 
To which all applications, upon submission, relating to either preliminary or final approval of subdivision and land development plans shall be referred.
B. 
Which shall make recommendations to the Board of Supervisors concerning approval, disapproval, modification, granting of waivers, and conditions of approval of such plans. In making such recommendation, the Planning Commission shall refer specifically to that section of this chapter or any statute or other ordinance or regulation applicable to the recommendation.
A. 
In any case in which an applicant demonstrates to the satisfaction of the Board of Supervisors that literal compliance with any provisions of this chapter would be unreasonable, would cause undue hardship as applied to the proposed subdivision or land development, or when alternative standard(s) can be demonstrated to provide equal or better results, in accordance with Section 512.1 of the Pennsylvania Municipalities Planning Code,[1] the Board of Supervisors may grant a modification or waiver to such provision(s), provided that the spirit and intent of this chapter is observed and that the public health, safety, and welfare is assured.

Editor's Note: See 53 P.S. § 10512.1
B. 
All requests for a waiver shall be in writing and shall accompany and be a part of the application for subdivision or land development. The request shall state in full the grounds and facts upon which the request is based, the provision or provisions of the ordinance involved, and the minimum modification necessary.
C. 
In granting waivers, the Board of Supervisors may impose such conditions as will, in its judgment, secure substantially the objectives of the standards and requirements so modified.
D. 
In no case shall the amount of escrow and bonding be reduced from that specified elsewhere herein.
