[Ord. 187, 4/18/2008]
1.
Existing Nonconforming Lots.
A.
Nonconforming Lots in All Districts. A nonconforming lot, separated in ownership from any adjoining tracts of land on the effective date of this Chapter may be used for a one family residence in any district in which such use is permitted provided such lot shall be developed in conformity with all applicable district regulations other than minimum lot area, lot width, side yard and rear yard. Existing small lots meeting the above stipulations shall comply with the following; provided, that no one family residence shall be erected upon a lot having a width of 58 feet or less, except pursuant to variance application procedures as hereinafter set forth:
One-Family Residences | ||||
|---|---|---|---|---|
For Lots Having a Width (In Feet) Greater than but less than | Minimum Side Yard (In Feet) | Total Both Side Yards (In Feet) | Minimum Rear Yard (In Feet) | |
99 | 150 | 20 | 45 | 20 |
79 | 100 | 15 | 35 | 15 |
59 | 80 | 12 | 30 | 10 |
B.
Nonconforming Lots in Nonresidential Districts. If a nonconforming lot is located in a nonresidential district then a building may be constructed on it for any use permitted in the district in which the lot is located provided that the off-street parking and loading requirements and all yard requirements for the applicable district are complied with.
2.
Exceptions to Yard and Height Requirements.
A.
Entries and Porticos. A roofed-over or unenclosed projection in the nature of an entry or portico, not more than eight feet wide and extending not more than six feet out from the wall of the building shall be exempt from front yard requirements when the building otherwise complies with all other yard requirements of this Chapter.
B.
Porches. A roofed-over porch, not in excess of 12 feet wide, may project into the required rear yard provided such projection is not located closer than 15 feet from any rear or side lot line.
C.
Setback Exception. When an unimproved lot is situated between two improved lots, each having a principal building within 20 feet of the side lot line of the unimproved lot, the front yard may be reduced to a depth equal to that of the greater front yard of the two adjoining lots but not less than 20 feet in residential districts and 10 feet in nonresidential districts.
D.
Front Yards on Narrow Roads. On roads with less than a forty-foot right-of-way, the front yard setback shall be measured from the center line of the existing road, and 20 feet shall be added to the front yard setback.
E.
Exceptions to Height Regulations. District height limitations shall not apply to church spires, cupolas, domes, monuments, water towers, chimneys, smoke stacks, farm structures, silos, flag poles, utility poles. Radio and television masts, antennas or aerials shall be permitted to be attached to and extend above existing structures a maximum of 20 feet.
F.
Projection Architectural Features. Bay windows, cornices, eaves, fireplaces, chimneys, window sills, or other architectural features not required for structural support may project into the required side, front or rear yard not more than a total of three feet.
G.
Limited Township Exemption. The minimum lot area and minimum lot width and height requirements of this Part shall not apply to uses or structures located on Smithfield Township property, for uses and structures that are intended for a legitimate governmental, recycling, public utility, public health and safety purposes or other public benefit.
3.
Conservation Subdivisions. A conservation subdivision is one where lots or dwelling units are clustered closer together on a tract with the specific objective of creating large usable sections of open space on the remainder of the property and without substantially increasing density for the tract as a whole. Conservation subdivisions shall be allowed in any district where residential uses are permitted. The purposes of conservation subdivision include:
• | Guiding the development of Smithfield Township consistent with its adopted Comprehensive Plan. |
• | Guiding detailed analysis of parcels to identity the best areas for development and conservation. |
• | Maintaining the existing landscape character by preserving open spaces and natural resources. |
• | Preserving scenic views by minimizing views of new development from existing roads. |
• | Preserving prime agricultural and forest land by concentrating housing elsewhere. |
• | Providing common open space for recreation by home buyers and, if necessary, the community. |
• | Providing lot sizes, housing choices and building densities for all age and income groups. |
• | Providing buffering between residential development and nonresidential uses. |
• | Minimizing disturbance to the existing environment while accommodating growth. |
Provided below is an illustration, followed by the regulations that shall apply to such development in Smithfield Township: |
![]() |
A.
The Township Board of Supervisors shall be authorized, simultaneously with the approval of plans under the Smithfield Township Subdivision Ordinance [Chapter 22], to modify applicable provisions of this Chapter so as to accommodate conservation subdivision projects. Conservation subdivisions offer flexibility in design, facilitate the economical provision of streets and utilities and preserve open space. They shall be allowed within any Smithfield Township residential district and be processed pursuant to subdivision plat approval procedures.
B.
The Planning commission or Township Board of Supervisors may also suggest conservation subdivision, as a form of development, in those instances where conventional subdivisions or residential developments would cause significant loss of open space or otherwise result in significant negative environmental impacts. An alternative sketch plan employing this concept may be required.
C.
Conservation subdivisions provide for single and multi-family dwelling units wherein dwelling units are grouped in sections in order to maximize the amount of common open space and to preserve the natural features. Proposed developments shall be processed in the same manner as a major subdivision and in accordance with the standards below.
D.
Conservation subdivisions shall include at least five lots and 10 acres of contiguous land. The Planning Commission shall have the authority to request the submission of an alternative sketch plan, for any subdivision of 10 lots or more, depicting how the property might be developed using this technique. If this alternative sketch plan is determined to provide a superior design in accord with the purposes of this Chapter, the Board of Supervisors may offer a density bonus in return for use of the conservation subdivision technique. Such bonus shall be determined using the following criteria:
0% to 25% open space | No density bonus |
26% to 30% open space | 10% density bonus |
31% to 35% open space | 15% density bonus |
36% to 40% open space | 20% density bonus |
41% to 45% open space | 25% density bonus |
46% to 50% open space | 30% density bonus |
50% + open space | 35% density bonus |
Nothing herein, however, shall require the Township Board of Supervisors to offer a density bonus or full bonus in those circumstances where the site limitations are such that increased density would materially impact the quality of the natural environment, threaten public health and safety or excessively burden public services. These bonuses have been created concurrently with the lowering of densities in certain zoning districts (e.g., R-1 District minimum lot area with on-site sewage and on-site water has been increased from 40,000 square feet to 50,000 square feet). Where application of the density bonus results in a total potential build-out greater than that which was possible prior to the availability of density bonuses hereunder, the Board may limit the bonus to maintain a comparable overall density to that possible prior to the availability of bonuses.
E.
The maximum permitted number of dwelling units before density bonuses shall be determined from the sketch plan submitted for a conventional single-family subdivision with one unit per lot. Such yield plan shall illustrate all proposed lots, streets, right-of-way and other pertinent features. Although it must be drawn to scale, it need not be based on a field survey. Nevertheless, it must be a realistic layout 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, the type of sewage system proposed, and, if unsewered, the suitability of soils for subsurface sewage disposal. The yield plan shall also be based on minimum lot sizes and other development standards for the zoning district involved, excepting that the provisions of § 27-401, Subsection 2, shall not apply.
F.
Only single-family detached and two family dwellings shall be employed in this concept. All other dwelling types shall be considered multi-family dwellings.
G.
Development standards for streets, lot size, lot width, lot coverage and lot depth may be reduced, provided no dwelling structure (single-family or two family) is located on less than:
(1)
Forty thousand square feet of land where both on-site sewer and water facilities are to be provided.
(2)
Thirty thousand square feet of land where central water facilities and on-site sewer facilities are to be provided.
(3)
Fifteen thousand square feet of land where on-site water facilities and central sewer facilities are to be provided.
(4)
Seven thousand five hundred square feet of land where both central sewer and central water facilities are to be provided.
This shall not, however, preclude smaller lots for purposes of conveying title to individual property interests under condominium ownership where these development standards are otherwise met. A mix of lot sizes will be encouraged and up to 20% may consist of lots of 10 acres or more that shall be counted as open space for density calculation purposes, if deed restricted from further subdivision. Such lots shall not represent more than 50% of the open space, however, and shall be contiguous to such open space. Yard requirements may also be reduced, but in no instance to less than 20 feet for the front yard and 10 feet for the side and rear yards, except in instances where zero lot line development is proposed with compensating yards on the opposite side. Notwithstanding these yard requirements, however, all principal structures shall be separated by a distance of at least 40 feet. Also, no more than 35% of any given acre shall be covered with impervious surface in the form of access drives, parking areas or structures. |
H.
No individual parcel of common open space shall be less than one acre except as to roadway median strips, traffic islands, walkways, trails, courtyards, play areas, recreation facilities, drainage ways leading directly to streams, historic sites or unique natural features requiring common ownership protection. No more than 50% of the permanent open space may consist of wetlands, floodplains, slopes of 25% or more, water bodies and other undevelopable areas unless the same have been incorporated into the open space in such a manner as to make substantial practical use of these areas for trails, other active recreational uses (e.g., ballfields, golf courses and ski slopes) or similar development features, including use for stormwater detention and sewage treatment (see Subsection 3K). Such determination shall, however, be solely in the discretion of the Township Board of Supervisors. The Township may also require open space linkages with adjoining properties, set-asides of active recreation area for residents and fronting of up to 50% of lots on open spaces. All open space dedicated to such recreational use shall be accessible by all residents of the conservation subdivision.
I.
The open space resulting from conservation subdivision design shall be permanently protected through a conservation easement that limits future development and requires conservation of open spaces consistent with the detailed requirements of this Chapter. The easement shall be titled to a property owners association (POA), land trust, municipality or other public entity (e.g., the County or School District) and/or placed under the management of such an organization to ensure the perpetual maintenance of the open space in its generally existing condition, which land may be used for any Township approved open space purpose including farming, active or passive recreational use and similar activities that will effectively preserve open spaces and the existing landscape character, prior to the sale of any lots or dwelling units with the subdivision.
J.
Membership in any POA to which open space is to be dedicated shall be mandatory for each property owner within the subdivision and successive owners with voting of one vote per lot or unit and the subdivider’s control, therefore, passing to the individual lot/unit owners on sale of the majority of the lots or units. All restrictions on the ownership, use and maintenance of common open space shall be permanent and the POA shall be responsible for liability insurance, local taxes, and maintenance of all open space, recreational facilities and other commonly held amenities. Each property owner must be required to pay their proportionate share of the POA’s cost and the POA must be able to file liens on the lot/unit owner’s property if levied assessments are not paid. The POA must also have the ability to adjust the assessment to meet changing needs.
K.
Wells and sewage treatment systems of either an individual or community nature may be located within or extend into open space areas provided that land occupied by for infrastructure associated with such systems shall not count toward open space requirements and further provided that subsurface sewage disposal methods are employed, all required isolation distances are observed and the ownership and maintenance responsibilities associated therewith are clearly defined in agreements submitted for approval as part of the subdivision application. No application shall be approved that does not provide buyers of lots served by individual or community subsurface systems with both the legal authority and the responsibility, individually or collectively, to maintain all sewer and water facilities on a continuing basis. Likewise, portions of street right-of-ways may be included within the required open space where such portions are not cleared in conjunction with the initial street construction.
