A.
This section allows an applicant the option to reduce the minimum lot areas on tracts of land if the applicant proves to the satisfaction of the Zoning Hearing Board that all of the requirements of this article will be complied with.
(1)
Cluster purposes. To allow flexible development of areas with sensitive natural features in such a way as to: avoid severe soil erosion and sedimentation; avoid severely increased stormwater flows and speeds; steer development to those areas that are more physically suited for it; avoid construction of steep roads that are difficult, time-consuming and expensive to maintain and snow plow; avoid increased use of steep roads and driveways that are dangerous to drive upon in snow and ice; conserve forested areas that are an important part of the ecological cycle, providing for groundwater recharge, air pollution reduction and wildlife habitats; reduce construction costs; allow all property owners a reasonable use of their land, related directly to the natural features and location and accessibility of the land; and encourage the preservation of significant areas of common open space.
(2)
The term "cluster development" shall mean a residential cluster development meeting the requirements of this § 135-351 and which is approved as a special exception use. A cluster development shall only include single-family detached dwellings, uses meeting the requirements for preserved open space, and their customary accessory uses. In addition, single-family semidetached dwellings may be permitted where specifically authorized.
B.
A tract may be eligible for approval for a cluster development if it includes a minimum of five contiguous acres. The minimum tract size may be reduced to two acres if the development will result in new publicly owned preserved open space immediately abutting existing publicly owned recreation land.
(1)
Lots of less than 1/2 acre that were previously granted final subdivision approval as part of a residential development shall not be recombined and resubmitted under this article.
(2)
For the purposes of this article, the term "total area of the tract" shall mean the total lot area, not including areas within the existing and future rights-of-way of existing streets. The total area of the tract may include: the right-of-way of any new future streets proposed within the tract; and any proposed open space.
(3)
Areas used for a principal nonresidential use and related parking (other than permitted open space) shall not be included within the land areas used to calculate compliance with this section.
C.
The cluster development shall be designed as a unified, coordinated residential development, and shall be approved within a development plan controlled by a single development entity. After final subdivision approval and within an approved development agreement(s), an applicant may sell lots or phases to other parties, provided that the development agreements clearly provide for a proper division of responsibilities to ensure compliance with the approved development plan.
D.
The application shall be submitted and acted upon by the Zoning Hearing Board as a special exception use, after review and recommendation by the Planning Commission.
E.
Reduction of lot width and lot area.
(1)
If approved as a cluster development ("CD"), then the minimum lot area and minimum lot width of the following districts may be reduced as follows, provided that the minimum preserved open space on the entire tract meets the requirement stated below, and provided that all other Township requirements are met.
(a)
If a particular situation is not described in the first column, then a cluster development shall not be permitted in that situation.
Zoning District | Noncluster Minimum Lot Area2 (square feet) | Noncluster Minimum Lot Width (feet) | Permitted Minimum Lot Area in a CD2 (square feet) | Permitted Minimum Lot Width in a CD (feet) | Minimum Preserved Open Space on the Tract1 (percent) |
|---|---|---|---|---|---|
OS with both approved central water and central sewerage services [Amended 3-16-2015 by Ord. No. 293-2015] | 87,130 | 150 | 12,0003 | 100 | 70 |
R with both approved central water and central sewerage services | 43,560 | 100 | 12,0003 | 70 | 60 |
R-1 with both approved central water and central sewerage services | 20,000 | 75 | 10,0003 | 70 | 40 |
Notes: |
|---|
1Shall be calculated based upon the "Total Area of the Tract" [see definition in Subsection B(2)]. |
2Except where steep slope regulations of this chapter require a larger lot size. |
3The minimum front, side and rear yards may each be reduced by five feet less than the depth that would otherwise be required by the zoning district the CD is to be located in. |
Non-cluster requirements are summarized in the above table for information purposes only. |
(2)
Semidetached dwellings. Up to 50% of the dwelling units within a cluster development may be semidetached dwelling units. Each dwelling unit shall be on its own lot. In such case, the minimum lot area stated above may be reduced to 8,000 square feet for each semidetached dwelling unit, provided that the average of all lot areas of all dwelling units is greater than 12,000 square feet.
F.
Other requirements. Only requirements that are specifically stated in this article as being adjusted shall differ from what would otherwise apply to a conventional noncluster development. All other requirements of this chapter and Chapter 119, Subdivision and Land Development, shall still apply to a cluster development.
G.
Conditions for cluster approval. In addition to the specific requirements of this section, a cluster development shall only be approved as a special exception use if the applicant proves to the satisfaction of the Zoning Hearing Board, based upon review by the Planning Commission, that the following conditions will be met:
(1)
That the cluster development would clearly serve a valid public purpose that would result in a development that would be superior to what would result if the land would be developed as a noncluster development. Such valid public purposes include but are not limited to the following:
(a)
The permanent preservation of forests, steep slopes, wetlands, creek valleys, highly scenic areas or other sensitive natural features.
(b)
The permanent preservation of a substantial area of land in crop farming or plant nursery uses, in a tract of proper size and configuration that allows for efficient agricultural use and that properly considers the issue of compatibility between the agricultural uses and homes.
(c)
The dedication of public parkland at a site deemed appropriate, in writing, by the Board of Supervisors, and that involves land that is clearly suitable for active and/or passive recreation.
(d)
The permanent preservation of land for recreation, primarily outdoor, that will serve large numbers of the public, and thereby reduce demand for publicly funded recreation facilities.
(e)
The clustering of homes in a location that will be substantially buffered from highly noxious, nuisance-generating uses, such as an expressway or major arterial street.
(2)
The applicant shall prove that the proposed cluster development has been designed in full consideration of important natural features, including mature woodlands, creek valleys, steep slopes and wetlands. The natural features of the site shall be a major factor in determining the siting of streets, lots, dwelling units and preserved open space. At a minimum, the applicant shall prove that areas along perennial creeks shall be preserved in their natural state, except for landscaping, erosion control improvements, public recreation improvements, and needed utility, street and driveway crossings.
H.
Preserved open space.
(1)
Minimum amount of preserved open space. Subsection E above states the minimum percentage of the tract area within a cluster development that shall be permanently preserved as preserved open space. Such preserved open space shall be preserved by one of the methods specified in this section. The method(s) to be used to own, preserve and maintain the open space shall be acceptable to the Zoning Hearing Board.
(2)
Open space standards. Required preserved open space shall meet all of the following requirements:
(a)
Such open space shall be permanently deed-restricted or protected by an appropriate conservation easement to prevent the use of the land for: the construction of buildings or any commercial purpose (other than uses and buildings permitted by this section); or commercial forestry (other than routine thinning of woods). Land approved as required preserved open space shall only be used for approved recreation uses, a nature preserve, a golf course, and approved agricultural uses.
(b)
Open space required in a cluster development shall be in addition to any recreation land dedication or recreation fee requirements that may be required under another section of this chapter or the Subdivision and Land Development Ordinance (SALDO). However, if more than 40% of a cluster development tract is preserved as open space under this article, then additional recreation land dedication or fees shall not be required under the SALDO.
(c)
The applicant shall prove that the disturbance of natural slopes over 15%, wetlands, mature forests and other important natural features within preserved open space areas will be minimized.
(d)
Improvements to open spaces. The application shall include a detailed and legally binding (if approved) description of what improvements the applicant will make to any land intended to be publicly dedicated to make it suitable for its intended purpose.
[1]
Examples of such improvements for areas intended for passive recreation include preservation and planting of trees, development of nature, bicycle or jogging trails, the stabilization of creek banks and the removal of undesirable vegetation.
[2]
Examples of such improvements for areas intended for active recreation include rough grading of land to create land suitable for free-play fields for youth.
(e)
All proposed open spaces shall be cleared of construction debris, materials from illegal dumping and any rocks that were not naturally on the land, unless those rocks are incorporated into landscaping improvements.
(f)
The applicant shall prove that all required open space would be suitable for its intended and approved purposes.
(g)
Lots and open spaces shall be located to promote pedestrian and visual access to preserved open spaces whenever possible.
(h)
Required common or public open space shall be safely and conveniently accessible to residents of the cluster development. Any designated pedestrian crossings shall be placed at locations that provide acceptable sight distance.
I.
Steep slopes.
(1)
A lot required to have a larger minimum lot area under another Township regulation because of steep slopes shall not be permitted to be reduced in lot area under this article. However, through the use of the smaller minimum lot areas in this article, the lot layout may be able to be revised to move proposed building sites away from steeply sloped portions of a tract so that requirements for larger lots might no longer apply.
(2)
No construction of principal buildings shall occur on natural slopes of over 20%. Streets shall be located to minimize alteration of such slopes.
J.
Phasing. Any phasing of a cluster development shall be approved by the Township under Chapter 119, Subdivision and Land Development. Such phases shall ensure that the requirements of this article would be met after the completion of any one phase, and that the development could properly function without the construction of additional phases.
K.
Maintenance of open space. A legally binding system shall be established to oversee and maintain land that will not be publicly owned. Any homeowner association shall generally follow the provisions of Section 705f, Parts (1) and (2), of the Pennsylvania Municipalities Planning Code,[1] as amended. Legal documents providing for ownership and/or maintenance of required open space shall be reviewed by the Township Solicitor or Zoning Hearing Board Solicitor and approved by the Zoning Hearing Board prior to recording of the deeds.
L.
Methods of preserving open space.
(1)
The method of ownership and use of any required preserved open space shall be determined prior to preliminary subdivision or land development approval. Except within the OS District, the Township shall be given right of first refusal at the time of such review to accept proposed open space as public open space. Required open space shall be permanently preserved by one or a combination of the following methods:
[Amended 3-16-2015 by Ord. No. 293-2015]
(a)
Dedication to the Township as public open space, if the Board of Supervisors agree, in writing, to such dedication.
(b)
Dedication to Lancaster County as public open space, if the county's governing body agrees, in writing, to such dedication.
(c)
Dedication to the Elizabethtown Area School District or Donegal Area School District, if such Board of Education agrees, in writing, to accept such dedication and to use and maintain the land for public school buildings and/or related open space.
(d)
Dedication to a homeowners' association as preserved open space, with the homeowners legally bound to pay fees for the maintenance and other expenses of owning such land, and with such homeowners' association being incorporated with covenants and bylaws providing for the filing of assessments and/or municipal liens for the nonpayment of maintenance costs for preserved open space that is not publicly owned.
[1]
Such responsibilities shall be specified as part of each deed prior to sale of each lot or dwelling unit. The Township may delay a dedication of maintenance responsibilities by a developer to a homeowners' association until such association is incorporated and able to maintain such land.
(e)
Dedication of the land to an established nature conservation organization acceptable to the Zoning Hearing Board.
(f)
Dedication of a permanent agricultural preservation easement to the County Agricultural Preserve Board.
(g)
Operation as a bonafide golf course, with a minimum lot area of 30 acres that do not include buildings or on-road vehicle parking.
(h)
Operation by a private entity of a recreation use permitted and approved within the applicable district regulations.
(2)
The Zoning Hearing Board shall only approve a cluster development if the applicant proves there will be an acceptable method to ensure permanent ownership, preservation and maintenance of the required open space.
(a)
Proper notations shall be required on the recorded plan. For example, if the preserved open space is intended to be owned by a homeowners' association as recreation land, a statement should be included that the designated open space "shall not be further subdivided and shall not be used for the construction of any nonrecreation buildings."
(3)
Township maintenance. Mount Joy Township shall be under no obligation to maintain any open space unless the Board of Supervisors specifically accepts such responsibility in writing.
(4)
Type of maintenance. Where the open space would not be dedicated to a government entity, the subdivision plan shall state the intended type of maintenance of the open space. The following classes of use and maintenance may be used, or other classes that are clearly described within and approved as part of the plan submittal:
(a)
Lawn: A grass area with or without trees which may be used by the residents for a variety of purposes and which is intended to be mowed regularly.
(b)
Natural area: An area of attractive desirable natural vegetation that is primarily intended for passive recreation, with minimal maintenance. Noxious and poisonous weeds should be controlled. Additional trees, as appropriate, and wildflowers are recommended to be planted.
(c)
Recreation area: An area designated for a specific recreation use, including but not limited to tennis, swimming, shuffleboard, playfields and/or children's play equipment. Such areas shall be maintained so as to be safe and appropriate for the intended use.
(d)
Agricultural area: An area designated for family vegetable plots, a plant nursery, hayfields, Christmas Tree Farm, crop farming or other Township-approved agricultural uses.
(5)
If required open space will not be dedicated to a government entity, then legally binding documents providing for the ownership and maintenance of open space shall, at a minimum, state that the land may only be used for Township-approved purposes, unless a change in use is subsequently approved, in writing, by the Zoning Hearing Board as a special exception use.
(6)
Preserved open space. Areas used to meet minimum preserved open space requirements shall not include any of the following:
(a)
Legal rights-of-way of existing and proposed streets;
(b)
Vehicle streets or driveways providing access to lots other than the open space;
(c)
Land beneath building(s) or land within 20 feet of a building (other than recreation buildings permitted within the open space, and other than agricultural buildings and a farmstead which are permitted within land approved by the Township for agricultural preservation);
(d)
Off-street parking (other than that clearly intended to serve recreation uses permitted within the open space);
(e)
Area(s) needed to meet a requirement for an individual building lot other than the approved open space;
(f)
Area(s) deeded over to an individual property owner for his or her own exclusive use, except for land approved by the Township for agricultural preservation or commercial recreation uses;
(g)
Land beneath or within 30 feet of each side of each of the following: overhead electrical transmission lines of 35 kilovolts or greater capacity; the towers/poles supporting such lines;
(h)
Land that does not have suitable pedestrian access points;
(i)
Areas including a stormwater detention basin, except for a basin or portions of a basin that the applicant proves to the satisfaction of the Zoning Hearing Board would be reasonably safe and useful for active or passive recreation during the vast majority of weather conditions;
(j)
Portions of land that have a width of less than 20 feet;
(k)
Land that includes commercial recreation uses, except that the following areas may be included as preserved open space if they are permitted in the applicable zoning district and also meet the other conditions for preserved open space of this chapter:
(l)
Land that includes a central sewage treatment plant or pumping station.
M.
Transfer of development rights. Clustering under this section shall not be combined with the transfer of development rights.
N.
Landscaping plan. An application for a cluster development shall include a landscape planting and preservation plan prepared by a registered landscape architect.
(1)
Such plan shall show the locations, general species and initial sizes of landscaping to be planted within the preserved open space and throughout the tract.
(2)
Such plan shall also show that existing substantial healthy trees will be preserved to the maximum extent reasonable. The methods to ensure preservation during construction shall be described.
(3)
Landscaping shall also be used as appropriate to filter views of denser housing from any adjacent housing that is less dense.
