A. 
Residential uses.
(1) 
On tracts eight acres or larger, the following three conservation subdivision options are permitted by right:
(a) 
Option 1, neighborhood lots: single-family detached dwellings with open space.
(b) 
Option 2, estate lots: single-family detached dwellings at reduced density, on larger lots and with no open space.
(c) 
Option 3, country properties: single-family detached dwellings at further reduced density, on larger lots with no open space. Up to two accessory dwelling units shall also be permitted in Option 3.
(2) 
Proposals for conservation subdivisions on tracts (existing as of March 1, 2006) eight acres or larger involving three lots or less shall be exempt from the requirements of Subsection A(1) above.
(a) 
Lots under this Subsection A(2) shall meet the requirements of §§ 150-12 through 150-17.
(b) 
Where development of less than the entire tract is intended, or where the tract is intended to be developed at less than maximum density, the Board of Supervisors may require the applicant to file a sketch development plan for the entire parcel.
(3) 
All accessory uses and structures shall comply with accordance with Article XXIV.
[Added 5-19-2021 by Ord. No. 284]
Determination of the maximum number of dwelling units for a conservation subdivision in Option 1 shall be based upon a yield plan, described in Subsection A below. The maximum number of dwelling units in Options 2 and 3 shall be based on the gross tract area and calculated as set forth in Subsections B and C below.
A. 
Density in Option 1. The maximum number of dwelling units in Option 1 shall be based on a yield plan, which shall meet the following requirements:
(1) 
Yield plans shall be prepared as conceptual layout plans in accordance with the standards of Chapter 130, Subdivision and Land Development, containing proposed lots, streets, rights-of-way, and other pertinent features. Yield plans shall be drawn to scale, but need not be based on a field survey. The layout shall be demonstrably compliant with all applicable zoning regulations and entirely feasible from an engineering standpoint, reflecting a development pattern that could reasonably be expected to be implemented, taking into account the presence of wetlands, floodplains, steep slopes, existing easements or encumbrances and, if not served by central sewage disposal facilities, the ability of the site to utilize on-lot, soils-based sewage disposal methods.
(2) 
The yield plan shall identify the site's primary and secondary conservation areas, as identified in the existing resources/site analysis plan.
(3) 
Sewage disposal systems. On sites not served by central sewage disposal facilities, density shall be further determined by evaluating the number of homes that could be supported by individual soils-based sewage disposal methods. For the purposes of determining density under this section, this standard shall exclude holding tanks, individual stream discharge systems and evapotranspiration systems. Based on the existing resources/site analysis plan and observations made during an on-site visit of the property, the Planning Commission or Board of Supervisors shall select a ten-percent sample of the lots considered to be marginal for on-lot sewage disposal. The applicant shall provide evidence that these lots meet the standards for an individual soils-based septic system. Should any of the lots in a sample fail to meet the standard for an individual soils-based septic system, those lots shall be deducted from the yield plan and a second ten-percent sample shall be selected by the municipal planning commission and tested for compliance. This process shall be repeated until all lots in a given sample meet the standard for an individual soils-based septic system. The applicant shall be granted the full density determined by the yield plan.
(4) 
Yield plan dimensional standards.
(a) 
The following dimensional standards shall be used in the development of a yield plan. Lots shall comply with all requirements of Chapter 130, Subdivision and Land Development. Lot areas shall be calculated as provided in the definition of "lot area calculation" in Article III.
[1] 
Minimum lot area: 80,000 square feet
[2] 
Minimum lot width: 250 feet.
(b) 
Lots which front on secondary collector or primary streets shall have a minimum lot width measured at both the building and street lines of at least 250 feet. Flag lots shall not be permitted along collector or primary streets.
(c) 
Front yard:
[1] 
On rural, residential, cul-de-sac and secondary feeder streets: 75 feet.
[2] 
On secondary collector and primary streets, and scenic roads: 100 feet.
[3] 
Rear yard: 100 feet.

Side yard: 50 feet.
B. 
Density in Option 2. The maximum number of dwelling units in Option 2 shall equal one dwelling unit per 160,000 square feet of gross tract area.
C. 
Density in Option 3. The maximum base density in Option 3 shall equal one principal dwelling unit per 10 acres of gross tract area. In addition, up to two accessory dwelling units are permitted on a lot, incidental to the primary permitted use and not conducted as an independent principal use, provided the following regulations are met:
(1) 
The accessory dwelling unit shall be located within the principal dwelling unit or in existing or new outbuildings (such as barns, stables, carriage houses, garages, and spring houses) and shall be designed to harmonize with the appearance of the principal dwelling.
(2) 
On lots less than 10 acres but at least five acres in area, a maximum of one accessory dwelling unit is permitted. On lots 10 acres or larger, up to two accessory dwelling units are permitted.
(3) 
The gross floor area of one accessory dwelling unit shall not exceed 1,200 square feet. The gross floor area of the other accessory dwelling unit, where permitted, shall not exceed 950 square feet. Under this section, existing historic accessory buildings more than 75 years old exceeding these floor area limits may be permitted to be used as an accessory dwelling unit, and shall not be required to meet the setback requirements set forth in § 150-110.6.
(4) 
No part of an accessory dwelling unit shall be located more than 500 linear feet from any point on the principal dwelling, except for an existing historic accessory building.
(5) 
Accessory dwellings shall not be permitted to have an additional accessory building, such as a garage.
(6) 
Building permits for new accessory dwelling units (and use and occupancy permits for existing structures proposed for use as accessory dwelling units) shall not be issued until the applicant demonstrates that a restrictive covenant has been placed on the subject property prohibiting future enlargement of the accessory dwelling unit beyond that permitted herein. This restriction shall also be incorporated into the building permit. Issuance of permits for accessory dwelling units shall be contingent upon approval of the Montgomery County Health Department for appropriate sewage disposal systems.
D. 
In Options 2 and 3, dwelling unit calculations resulting in a fraction of 0.5 or greater shall be rounded up to the next higher whole number and a fraction of less than 0.5 shall be rounded down to next lower whole number.
E. 
In Options 2 and 3, lots shall be permanently restricted from future subdivision and land development by a deed restriction enforced by the Township or by a conservation easement held by the Township or a qualified conservation organization. The organization and the terms and form of the easement shall be approved by the Township.
F. 
Transfer of development rights. All or some of the units permitted under Subsections A, B and C above on one or more tracts may be transferred to one or more other tracts, by conditional use, provided the following conditions are met:

All tracts (whether "sending" or "receiving") shall be owned by the same legal or equitable owner.
(2) 
All tracts shall be located in the AGR Agricultural District or the LPD Land Preservation District.
(3) 
The applicant shall demonstrate that providing fewer or no units on one or more tracts and more units on one or more other tracts advances the purposes of conservation subdivision set forth in § 150-110.1 better than locating the maximum permitted number of units on each tract.
(4) 
The Board of Supervisors shall determine that one or more of the tracts is less suitable or not suitable for development (the sending tracts) and the other tracts are suitable for higher density development (the receiving tract), in accordance with the goals of the Worcester Township Comprehensive Plan and Open Space Plan.
(5) 
Permission to transfer units from one or more tracts to other tracts shall be otherwise subject to the requirements of Chapter 150, Zoning, and Chapter 130, Subdivision and Land Development, and any other Worcester Township regulations which apply to the development of the tract(s).
(6) 
The applicant shall enter into an agreement with the Township specifying:
(a) 
The maximum number of units permitted on each of the tracts;
(b) 
The minimum required open space on each tract, which shall meet the requirements of § 150-110.11C; and
(c) 
Other conditions as applicable.
(7) 
Prior to final approval of the plans for the sending or receiving tract, a deed of dedication to Worcester Township or a conservation easement running with the land and in favor of the Township or a conservation organization approved by the Township shall be established prohibiting any development of the sending tract, except as agreed in Subsection F(6) above and specifically permitted by Worcester Township, and shall be recorded in the Montgomery County Office of Recorder of Deeds. The terms and form of the deed of dedication or conservation easement shall be acceptable to Worcester Township.

At the time of preliminary plan submission, the applicant shall provide a draft open space management plan with sufficient detail to demonstrate feasible compliance with the provisions required under this section.
(c) 
The management plan shall be recorded with the final subdivision and land development plans in the Office of the Recorder of Deeds of Montgomery County, Pennsylvania.
(d) 
The Board of Supervisors may require as a condition of subdivision and/or land development approval that appropriate management contracts be established as evidence of the ability to adhere to the provisions of the approved management plan.
(e) 
In order to allow for the changing needs inherent in the perpetual management of land, the management plan shall contain a provision to the effect that it may be changed by written application to the Board of Supervisors. Approval of such application by the Board of Supervisors shall not be unreasonably withheld or delayed, so long as:
[1] 
The proposed change is feasible and is consistent with the purposes of preservation of open space set forth in this section and with the approved subdivision and land development plans; and
[2] 
The plan for such change avoids a likelihood of the obligation for management and maintenance of the land falling upon the Township without the consent of the Board of Supervisors.
(2) 
Failure to maintain facilities and corrective action.
(a) 
Upon default by any owner, homeowners' association, conservation organization, or other entity responsible for maintenance of open space and/or associated common facilities, where such maintenance is required under the terms of the open space management plan, homeowners' association or condominium documents, any subdivision and/or land development plan for the property, the zoning approval for the property, or under any applicable requirements of any Township ordinances, permits or approvals, or where such maintenance is otherwise necessary to abate a nuisance, emergency, hazard or other condition threatening persons or property or the public health, safety or welfare, the Township may, but shall not be obligated, to take the following actions:
[1] 
Upon 30 days advance written notice to the person, association or entity responsible for such maintenance (or any such lesser period as may be specified in the notice in instances of emergency) and the failure of the responsible individual, entity or association within such thirty-day period (or such lesser period in the event of an emergency) to perform the necessary maintenance and otherwise remedy the condition set forth in the Township's notice, to enter upon the open space, accessing the same through any other lands of such entity, association or individual as may be necessary, to perform such maintenance and take any other action necessary to correct the default in the Township's notice.
[2] 
Any and all costs incurred by the Township in connection with such notice and maintenance shall be paid by the responsible individual, entity or association within 10 days after written demand by the Township. Upon failure of the responsible entity, association or individual to pay such costs by the time required, there shall be added thereto interest at the rate of 15% per annum as well as all costs incurred by the Township in collection thereof.
[a] 
All such costs of maintenance, remediation, notices, and collection, including court costs and attorney's fees, shall constitute a municipal lien and be enforceable as such against the responsible entity, individual or association.
[b] 
Such lien shall be filed by the Township in the office of the Prothonotary of Montgomery County, Pennsylvania.
D. 
Open space performance bond. Where intended as common or public amenities, all landscape improvements, plantings, accessways, and recreational facilities within designated open space areas shall be provided by the developer. Financial security acceptable to the Township shall be required to cover costs of installation of such improvements in the open space area. The financial security shall be in the same form and adhere to the same conditions as otherwise required for proposed improvements by Chapter 130, Subdivision and Land Development.
