1. Introduction

1.1. Vision

1.1.1. Lancaster County is a unique mosaic of tradition and modernity, development and preservation. As the County anticipates adding 95,000 people by 2030, it will become imperative that zoning standards encourage compact, transit-friendly development proposals. This Code Outline provides progressive zoning opportunities supportive of form-based and performance elements in additiontotheinstallationofafirst-phasebusrapidtransitsystem.Combining intelligent land use and transportation decisions will help Lancaster County achieve diverse urban economic centers inclusive of cultural heritage while planning for the protection of its invaluable agricultural and environmental features.

1.2. Purpose

1.2.1. Lancaster County has adopted 13 Urban Growth Areas involving 43 municipalities within the County. These Urban Growth Areas are intended to focus new development where services currently exist or are anticipated in the future. Within the Urban Growth Areas the County has adopted Five Key Objectives:

1.2.1.a. Increase the proportion, density and intensity of development with the UGAs.

1.2.1.b. Place a new emphasis on compatible reinvestment, infillandredevelopment.

1.2.1.c. Improve the character and form of new development in UGAs.

1.2.1.d. Increase housing choice and affordability.

1.2.1.e. Increase employment opportunities.

1.2.2. Outside the Urban Growth Areas the County has adopted a Rural Strategy with three key objectives:

1.2.2.a. Establish Designated Rural Areas

1.2.2.b. Reduce nonrural development outside of UGAs and direct it to Rural Centers to maintain the form and character of rural areas.

1.2.2.c. Maintain the viability of the rural economy, including agriculture and other economic activities that depend on rural resources or a rural location.

1.2.3. Within the Designated Rural Areas the adopted policies include Designated Natural Areas, and two categories of

Page 7: Lancaster Model Code Outline

UNIVERSITY OF PENNSYLVANIA | CPLN 702 | URBAN DESIGN STUDIO | SPRING 2012 7

Agriculutural Uses. There are also policies for four types of Rural Centers:

1.2.3.a. Village Growth Areas

1.2.3.b. Crossroads Communities

1.2.3.c. Rural Business Areas

1.2.3.d. Rural Neighborhoods.

1.2.4. The purpose of this code outline is to help translate Lancaster County’s adopted growth management policies into development regulations that can be incorporated into local codes by the municipalities within the County.

2. Organization and Objectives

2.1. Overview

2.1.1. This code outline seeks to maintain the general organizational structure of the Lancaster County Growth Management Plan. In doing so, the code outlines 12 distinct zones which relate to the County’s rural and urban strategies. Each zone is designed to help the County meet its key objectives in terms of population growth and land consumption by facilitating compact, walkable development. A vision for each zone is used to guide the spatial and aesthetic components found within to ensure

Page 8: Lancaster Model Code Outline

SPRING 2012 | URBAN DESIGN STUDIO | CPLN 702 | UNIVERSITY OF PENNSYLVANIA8

development achieves a desired character. Each zone incorporates multiple designations found within the County’s Zoning Lexicon in ordertosimplifythezoningcodeandprovidegreaterflexibilityindevelopment opportunities.

3. Districts

3.1. Overview

3.1.1. Purpose

3.1.1.a. Zoning codes regulate the size, bulk, use, and location of buildings to protect public health, safety and welfare. Subdivision codes regulate the division of properties into lots, the location,configuration,dimensions,andgradingofstreets,andthe management of environmental conditions such as stormwater and erosion, for the same purpose.

3.1.1.b. Thisdocumentoutlinesaunifiedcodethatisintendedto include both zoning and subdivision regulations. In addition the maps on which it is based incorporate detailed information

about the natural environment and existing buildings and infrastructure.. The code outlines regulations for land uses, buildings, lots, lot coverage, streets – including street design standards, public space, blocks, and densities. Additionally, this Code regulates Environmental Performance and includes requirements for Renewable Energy

3.1.2. The Outline Code describes regulations that can be applied by local governments throughout Lancaster County and is intended to incorporate both existing and future development.

3.1.3. Forrequirementsandconditionsforspecificlocations,referto the Code Map to determine the applicable District.

3.2. SC: Scenic and Recreational Zone

3.2.1. Description and Purpose

3.2.1.a. The SC Zone comprises land with high scenic, recreational, and natural resource value, and land unsuitable for development because of environmental constraints such as steep slopes,wetlands,andfloodplains.Theintentofthiszoneisthatsuch areas should be permanently protected from inappropriate development and incorporated as much as possible into an open space / greenway network that extends both inside and outside the Urban Growth Areas.

3.2.1.b. All development in SC zones requires a special permit andpreliminaryandfinalapprovalofadevelopmentplan.

3.2.1.c. Development may include active and passive recreationareassuchasbaseballfields,golfcourses,hikingtrails, scenic overlooks, and buildings, roads and parking places that are accessory to these uses. Agricultural and Silvicultural

3.5. CC: Crossroads Communities

3.5.1. Description and Purpose

3.5.1.a. A Crossroads Community is an existing compact gathering of 20 to 50 dwellings with a distinct identity located in a rural area, typically at a crossing of two important local streets. A Crossroads Community often has a central gathering place and may have a few supporting commercial or public uses. The CC zone permits these communities to become the focus of a limited amount of residential and necessary local businesses as an alternative to locating such activities amid agricultural land. Only development that is compatible with the traditional character and scale of these small communities, and which is feasible to support with rural infrastructure, is permitted in a CC zone.

3.5.2. Size of CC Zones

3.5.2.a. RA CC zone should not comprise more than 40 acres and should not extend more than 600 feet from the center of the crossroads.

3.5.3. Density

3.5.3.a. The target residential density is 2.5 dwelling units per acre.

3.5.4. Permitted Uses

3.12. CD: Corridor District

3.12.1. Description and Purpose

3.12.1.a. Corridor Districts are intended to recognize and regulate existing commercial development along thoroughfares and highways where the prevailing development consists of separate commercial buildings and large areas of surface parking.. Regulations for this district are intended to mitigate environmental issues caused by stormwater runoff/impervious surfaces and to improve the pedestrian environment along the corridors. Given the close proximity to highways and thoroughfares Corridor Districts are viewed as promising areas for future development and incorporation of transit systems. If a new permanent transit station is established within a CD district, the zoning district should be changed to CN. The Transit Overlay District will also apply. Existing Residential development within CD districts should be remapped in order to be included in one of the mixed-use districts that permit residences.

3.12.1.b. New corridor districts are not permitted to be mapped in undeveloped or partially developed areas.

5.1. Environmental Protection Overlay

5.1.1. Purpose

5.1.1.a. The environmental protection overlay builds upon the Model Conservation Zoning District and Natural Resource Protection Standards designed by the Lancaster County Planning Commission. The intent of the overlay is to protect environmental systems such as sensitive habitats, forests, and watersheds and to protect the rights of the residents of the Lancaster County to clean air, pure water, and the natural, scenic, historic, and aesthetic values of the environment as set forth in Article I, Section 27 of the Pennsylvania Constitution. The performance criteria established in the environmental protection overlay were designed so as to permit municipalities of Lancaster County to accommodate their growth management needs in ways that minimize impacts to sensitive environmental areas. The standards

5.3. Historic Conservation District

5.3.1. Description and Purpose

Page 77: Lancaster Model Code Outline

UNIVERSITY OF PENNSYLVANIA | CPLN 702 | URBAN DESIGN STUDIO | SPRING 2012 77

5.3.1.a. The Historic Conservation District Overlay is intended to provide standards and regulations to existing or future historic districts throughout the County for the purpose of protecting the distinctive historical character of these districts and to regulate the erection, reconstruction, alteration, restoration, demolition or razing of buildings within the historic districts. The model in Lancaster County is the Heritage Conservation District in Lancaster City.

5.3.1.b. Under Pennsylvania Act No. 167, dated June 13, 1961, (P.L. 282) as amended by 1963 P.L. 27, Not 24 and 1980 P.L. 74 (53 P.S. 8001 et seq.), counties, cities, boroughs, incorporated towns and townships are authorized to create historic districts within their geographic boundaries providing for the appointment of Boards of Historical Architectural Review (HARB).

5.3.1.c. Additionally, Act 247, Article III Section 301(a)(6) of the Pennsylvania Municipalities Planning Code describes the purpose of a plan for the protection of natural and historic resources and sites with which Article VI establishes the basis for zoning in historic districts.

5.3.1.d. Historic Conservation Districts are overlay districts overthebasezoningdistricts,intendedtopreservethespecificcultural,architecturaland/orhistoricsignificanceofanexistingarea of a city or town. Regulations within a HC district are designed to protect the character and heritage of the area byrequiringapprovalofsignificantchangestotheexteriorofexisting buildings and reviewing new buildings that are added to the district to insure that they are appropriate to the form and style of its context. Public space within Historic Districts should facilitate walking and prioritize the pedestrian experience by maintaining ground level transparency, offering pedestrian crossings,lowtrafficspeedsandtreelinedstreets.

5.3.1.e. An HC District should be administered by a Historic District Review Commission, whose actions, while advisory tothePlanningCommission,shouldordinarilybethefinaldetermination.

5.3.1.f. HC Districts should be mapped where the preponderanceoftheconstructedenvironmenthasaspecifichistoric character that meets standards for historic preservation, for example the criteria for districts included in the National Register of Historic Places.

5.3.1.g. Permitted Uses, Lots, Minimum Lot Area, Minimum

Page 78: Lancaster Model Code Outline

SPRING 2012 | URBAN DESIGN STUDIO | CPLN 702 | UNIVERSITY OF PENNSYLVANIA78

Street Frontage, Setbacks, Building requirements, Open Space Requirements, are all determined by the underlying zoning district. However, when the Historic District Review Commission determines that elements, such as building height, are not compatible with the district, the Review Commission’s stricter standards prevail. The Review Commission can, and should, issue guidelines for exterior materials and design elements that will be compatible with the building exteriors prevailing in the HC District.

impervious surfaces. Cisterns are not required if structure includes green roofs purposed to minimize runoff. If walkways, driveways and parking areas are not constructed of permeable materials, a local retention facility must be included unless it is proves incompatible with the historic district. Its size should be proportionate to the area of impervious surfaces located on-site. Localized retention facilities must be provided at a distance no greater than State determined Best Management Practices.

5.3.3.f. Where poor soils are determined to be contributing to degradation of watersheds, efforts must be taken to increase groundwaterinfiltrationandreducestormwaterrunoff.

5.3.4. Renewable Energy Standards

7.4.1. For the purposes of the environmental overlay, Riparian CorridorsaredefinedbyabuffercreatedbytheWesternPennsylvania Conservancy for Lancaster County’s GreenScapes Green Infrastructure Plan of 2009. Riparian Corridor is intended as a measure of ideal corridor width, and is calculated from a baseof100metersfromtheedgeofthefloodplain,withvariationdepending on the quality of the stream, level of impervious cover, existing vegetation, and topography. While there may be existing land uses within areas deemed Riparian Corridor, this overlay is intended mitigate the impacts of new construction and sizeable retrofits.
