In addition to the standards in this Article VI, all subdivisions and land developments shall be designed in accord with the applicable requirements of the Borough's Zoning Ordinance.[1]
A.
Application. The standards and requirements contained in this Article VI shall apply to all subdivisions and land developments and are intended as the minimum for the preservation of the environment and promotion of the public health, safety, and general welfare, and they shall be applied as such by the Planning Commission and Council in reviewing and evaluating plans for all proposed subdivisions and/or land developments. Compliance with all standards shall be documented by the applicant at the time of initial application.
(1)
Planning. The development shall conform to the proposals and conditions shown in the Borough Comprehensive Plan and any local or regional plans adopted by the Borough. The streets, drainage, rights-of-way, school sites, public parks and playgrounds shown on the officially adopted plan or the Borough's Official Map shall be considered in the approval of all plans. In the case of major subdivisions and land developments, the applicant shall submit a narrative detailing how the development conforms to any applicable plan.
(2)
Contiguous lands. Where the owner of the site under consideration owns contiguous land suitable for development, the subdivision plan shall cover all such contiguous lands. This provision, however, may be waived in full or in part by the Council if it is not considered essential to the evaluation of the plans for the current development tract.
(3)
Improvements, specifications. Additional improvements or improvements of more stringent specifications may be required in specific cases where, in the opinion of the Council, such specifications are necessary to create conditions essential to the health, safety, and general welfare of the citizens of the Borough and/or to protect the environment of the Borough.
(4)
Hazard areas. Those areas which may present such hazards to life, health, or property as may arise from fire, flood or noise, or are considered to be uninhabitable for other reasons, shall not be subdivided for building purposes unless the hazards have been eliminated or the plans show adequate safeguards against the hazards. Sources for determining and evaluating potential hazards may include historical records, soil evaluations, engineering studies, expert opinions, standards used by licensed insurance companies, and adopted regional, county or local municipal policies.
(5)
Development design; remnants; neighboring development. All portions of a tract being subdivided shall be taken up in lots, streets, open lands, or other proposed uses, so that remnants and landlocked areas shall not be created. The layout of a subdivision shall also be planned with consideration for existing nearby developments or neighborhoods so that they are coordinated in terms of interconnection of open space, traffic movement, drainage, and other reasonable considerations.
(6)
Natural features. Care shall be taken to preserve natural features such as agricultural land, woodland and specimen trees, wetlands, watercourses, views, and historical features, such as buildings and stone walls, which will maintain the attractiveness and value of the land. Damming, filling, relocating or otherwise interfering with the natural flow of surface water along any surface water drainage channel or natural watercourse shall not be permitted except with the approval of the Borough and, where appropriate, the PA DEP and the United States Army Corps of Engineers.
(a)
Groundwater resources. This section is intended to ensure that the Borough's limited groundwater resources are protected for purposes of providing water supplies for its residents and businesses and to protect the base flow of surface waters. These regulations shall be applied in conjunction with those provided for in other sections of this chapter dealing with groundwater conservation and replenishment. The proposed subdivision and land development of any tract shall be designed to cause the least practicable disturbance to natural infiltration and percolation of precipitation to the groundwater table through careful planning of vegetation and land disturbance activities, the use of bioretention areas and infiltration trenches, and the placement of streets, buildings and other impervious surfaces in locations other than those identified on the existing resources and site analysis plan as having the greatest permeability where precipitation is most likely to infiltrate and recharge the groundwater.
(b)
Stream valleys, swales, springs, and other lowland areas. Stream valleys (which include stream channels and floodplains), swales, springs and other lowland areas are resources that warrant restrictive land use controls because of flooding hazards to human life and property, groundwater recharge functions, importance to water quality, and the health of aquatic communities and wildlife habitats. Such areas are generally poorly suited for on-site subsurface sewage disposal systems. The following activities shall be minimized:
[1]
Disturbance to streams and drainage swales.
[2]
Disturbance to year-round wetlands, areas with seasonally high water tables, and areas of surface water concentration.
[3]
Stream valleys, swales and other lowland areas warrant designation as conservation open space because of extreme limitations. They may also require adjoining buffer lands to be included in the conservation open space, to be determined by an analysis of the protection requirements of such areas on a case-by-case basis. In certain instances, hydric soils may be excluded from the conservation open space where it can be demonstrated that they are suitable for low-density residential uses and on-site sewage systems.
(c)
Woodlands. Woodlands occur extensively throughout the Borough, often in association with stream valleys and wet areas, poor and erodible agricultural soils, and moderate to steep slopes.
[1]
Woodland conditions within the Borough vary with respect to species composition, age, stocking, and health. They range from relatively recent post-agricultural young stands to mature mixed-age forests. Most woodlands in the Borough represent one or more of the following resource values:
[a]
As soil stabilizers, particularly on moderate to steep slopes, thereby controlling erosion into nearby streams, ponds, impoundments and roads. A closely related function is their enhancement of groundwater recharge.
[b]
As a means of ameliorating harsh microclimatic conditions, in both summer and winter.
[c]
As a source of wood products (i.e., poles, saw timber, veneer and firewood).
[d]
As habitats for woodland birds, mammals and other wildlife.
[e]
As recreation resources for walkers, equestrians, picnickers, and other related outdoor activities.
[f]
As visual buffers between areas of development and adjacent roads and properties.
[2]
Because of their resource values, all woodlands on any tract proposed for subdivision or land development shall be evaluated by the applicant to determine the extent to which such woodlands should be designated partly or entirely as conservation open space or development lands. Evaluation criteria shall include:
[a]
Configuration and size.
[b]
Present conditions (i.e., stocking, health and species composition).
[c]
Site potential (i.e., the site's capabilities to support woodlands, based upon its topographic, soil and hydrologic characteristics).
[d]
Ecological functions (i.e., in protecting steep slopes and erodible soils, maintaining stream quality, and providing for wildlife habitats).
[e]
Relationship to woodlands on adjoining and nearby properties and the potential for maintaining continuous woodland areas.
[3]
The evaluation of the tract's woodlands shall be undertaken by a forester, landscape architect, horticulturist or another qualified professional acceptable to the Borough. This evaluation shall be submitted as a report and made a part of the application for a preliminary plan. At a minimum, that report shall include one or more maps indicating boundaries and conditions of woodland areas accompanied by a report addressing the criteria in § 187-43A(6)(c).
[4]
In designing a subdivision and land development plan for any tract, the applicant shall be guided by the following standards:
[a]
Healthy woodlands exceeding one acre shall be preserved and designated as conservation open space areas to the maximum extent possible. Proposed site improvements shall be located, designed, and constructed to minimize the loss or degradation of woodland areas.
[b]
Developments shall be designed to preserve woodlands along roadways, property lines and lines occurring within a site, such as streams, swales, stone fences and hedgerows. Such lines and the native vegetation associated with them shall be preserved as buffers between adjacent properties and between areas being subdivided within a property. Preservation shall include ground, shrub, understory, and canopy vegetation.
[c]
Disturbance or removal of woodlands occupying environmentally sensitive areas shall be undertaken only when approved by the Planning Commission and on a limited, selective basis to minimize the adverse impacts of such actions. This shall include, but not necessarily be limited to, vegetation performing important soil-stabilizing functions on wet soils, stream banks, and sloping lands.
[d]
No clearing or earth disturbance (except for soil analysis for proposed sewage disposal systems) shall be permitted on a site before the completion of subdivision and land development agreements. The determination of sight distance clearances along roadways shall be made graphically and not by clearing on site prior to final plan approval.
(d)
Upland areas. These areas comprise fields, pastures, meadows, and former agricultural areas in early stages of woodlands succession, with fences, stone walls, tree copses and hedgerows, typically bordered by stream valleys and upland woodlands. These comprise the Borough's historic working landscape, dotted with historic houses, barns and other structures. They give the Borough much of its rural character. They also contain the greatest concentration of prime agricultural soils. Because of their openness and high visibility, development in these areas is likely to be most readily seen and disruptive to the historic landscape. Such areas sometimes provide habitat for wildlife, in conjunction with nearby woodlands and stream valleys. However, it is recognized that these areas also frequently offer the fewest constraints for development. Several elements of these working landscapes lend themselves to incorporation into the Borough's conservation open space network. These include prime agricultural soils and natural features which visually punctuate the landscape, such as hedgerows, tree copses, stone walls, and visually prominent places such as knolls and hilltops. These areas can also accommodate development, with preferred locations being the non-prime agricultural soils and lower topographic settings where development will be visually less obtrusive. Compact clustered residential designs, with coordinated architectural and landscape architectural themes, are encouraged in highly visible locations where future development cannot be avoided (such as at the far edge of open fields).
(e)
Slopes. Moderately sloping lands (15% to 25%) and steeply sloping lands (over 25%) are prone to severe erosion if disturbed. Erosion and the resulting overland flow of soil sediments into streams, ponds, and public roads are detrimental to water quality and aquatic life, and a potential hazard to public safety.
[2]
All grading and earthmoving on slopes exceeding 15% shall be minimized.
[3]
No site disturbance shall be allowed on slopes exceeding 25%, except grading for a portion of a driveway accessing a single-family dwelling when it can be demonstrated that no other routing which avoids slopes exceeding 25% is feasible.
[4]
On slopes of 15% to 25%, the only permitted grading beyond the terms described above shall be in conjunction with the siting of a single-family dwelling, its access driveway and the septic system.
[5]
Grading or earthmoving on all sloping lands of 15% or greater shall not result in earth cuts or fills whose highest vertical dimension exceeds six feet, except where, in the judgment of the Planning Commission, no reasonable alternatives exist for construction of roads, drainage structures and other required improvements, in which case such vertical dimensions shall not exceed 12 feet.
[6]
Roads and driveways shall, to the greatest extent possible, follow the line of existing topography to minimize the required cut and fill. Finished slopes of all cuts and fills shall be as required to minimize disturbance of natural grades.
(f)
Significant natural areas and features. Natural areas containing rare or endangered plants and animals, as well as other features of natural significance, exist throughout the Borough. Some of these have been carefully documented (e.g., by the Statewide Natural Diversity Inventory); whereas, for others, only the general locations are known. Subdivision applicants shall take all reasonable measures to protect significant natural areas and features either identified by the Borough's Map of Potential Conservation Lands or by the applicant's existing resources and site analysis plan by incorporating them into proposed conservation open space areas or avoiding their disturbance in areas proposed for development.
(7)
Historic structures and sites. The Borough's documented historical resources begin with the Native Americans in the early 18th century and extend through its colonial agricultural, residential and industrial development in the late 18th and 19th centuries. Plans requiring subdivision and land development approval shall be designed to protect existing historic resources. The protection of an existing historic resource shall include the conservation of the landscape immediately associated with and significant to that resource, to preserve its historic context. Where, in the opinion of the Commission, a plan will have an impact upon a historic resource, the developer shall mitigate that impact to the satisfaction of the Commission by modifying the design, relocating proposed lot lines, providing landscape buffers, or other approved means. Borough participation, review and approval of the applicant's interaction with the State Historical and Museum Commission with regard to the preservation of historic resources, as required for PA DEP approval of proposed sewage disposal systems, shall be required prior to preliminary plan approval.
(8)
Scenic viewsheds. The Borough has identified a number of scenic viewsheds in the Regional Recreation and Open Space Plan. All applications for subdivision and land development shall attempt to preserve the viewsheds by incorporating them into conservation open space or otherwise providing for building setbacks and architectural designs to minimize their intrusion. In instances where such designs fail to satisfactorily protect viewsheds, applicants will be required to provide landscape buffers to minimize their adverse visual impacts. The buffers shall be provided in accord with the Borough Zoning Ordinance[3] and Borough landscaping requirements.
(9)
Trails. When a subdivision or land development proposal is traversed by or abuts an existing trail customarily used by pedestrians and/or equestrians, the Council may require the applicant to make provisions for continued recreational use of the trail.
(a)
The applicant may alter the course of the trail within the tract for which development is proposed under the following conditions:
[1]
The points at which the trail enters and exits the tract remain unchanged.
[2]
The proposed alteration exhibits quality trail design according to generally accepted principles of landscape architecture.
[3]
The proposed alteration does not coincide with a paved road intended for use by motorized vehicles.
(b)
When trails are intended for public or private use, they shall be protected by a permanent conservation easement on the properties on which they are located. The width of the protected area in which the trail is located should be a minimum of 10 feet. The language of the conservation easement shall be to the satisfaction of the Planning Commission upon recommendation of the Borough Solicitor.
(d)
An applicant may propose and develop a new trail. If said trail is available for use by the general public and connects with an existing trail, the land area protected for said trail may be credited toward the conservation open space requirement of the Zoning Ordinance.[5]
(e)
Trails shall have a vertical clearance of no less than 10 feet.
(f)
Width of the trail surface may vary depending upon type of use to be accommodated but in no case shall be less than three feet or greater than six feet.
(g)
No trail shall be designed with the intent to accommodate motorized vehicles.
(10)
Boundary lines and reserve strips. Lot lines should follow municipal and county boundary lines rather than cross them. Reserve strips controlling access to lots, public rights-of-way, public lands or adjacent private lands are prohibited.
(11)
Water frontage and surface drainage. The damming, filling, relocating, or otherwise interfering with the natural flow of surface water along any surface water drainage channel or natural watercourse shall not be permitted except with approval of the Borough and, where required by state statute, the PA DEP or other applicable state agencies.
(12)
Community facilities and adopted plan requirements. Where a proposed park, playground, school, or other public use is shown in an adopted plan of the Borough and is located in whole or in part in a proposed development, the Council may require the reservation of such area, provided that such reservation is acceptable to the developer.
(13)
Walkways. Pedestrian interior walks may be required, where necessary, to assist circulation or provide access to community facilities (e.g., a park or school).
(14)
Storm drainage. Lots and/or parcels shall be laid out and graded to provide positive drainage away from buildings and to prevent damage to neighboring lots, tracts, or parcels.
B.
Planned improvements. Physical improvements to the property being subdivided and/or developed shall be provided, constructed and installed as shown on the approved preliminary plan.
C.
Improvements specifications. All improvements installed by the developer shall be constructed in accordance with the design specifications and construction standards of the Borough and advice of the Borough's Engineer.
(1)
Where there are no applicable Borough specifications, improvements shall, if approved by the Council, be constructed in accordance with specifications furnished by the Borough's Engineer, Monroe County Conservation District, Pennsylvania Department of Transportation, Pennsylvania Department of Environmental Protection, Bureau of Forestry or such other county, state or federal agency as may be applicable.
(2)
If there are no applicable Borough or state specifications, the Council may authorize that such specifications be prepared by the Borough's Engineer or an engineering consultant.
D.
Other ordinances. Whenever other Borough ordinances and/or regulations impose more restrictive standards and requirements than those contained herein, such other ordinances and/or regulations shall be observed; otherwise, the standards and requirements of this chapter shall apply.
