PORT COLUMBUS INTERNATIONAL FAR PART 150 NOISE COMPATIBILITY STUDY FINAL CHAPTER TWO AFFECTED ENVIRONMENT

Airports and aircraft operations generally have direct benefits and impacts on surrounding communities as aviation activity is inherently intertwined with its neighbors. This includes both positive and negative impacts. Identifying and evaluating land uses surrounding an airport is an important step in quantifying potential impacts through the Part 150 process. This evaluation identifies the residential and other noise-sensitive land uses around the Port Columbus International Airport (CMH). A discussion of the land use mapping methodology and zoning information is provided in Appendix D, Land Use Methodology. 2.1 AIRPORT LOCATION

CMH is located on the eastern edge of the City of Columbus, to the north of the cities of Bexley and Whitehall and west of the City of Gahanna and Jefferson Township. These jurisdictions generally share both the benefits and the potentially negative impacts of airport operations at CMH, and therefore, are the subject of the land use evaluation in this study.

2.1.1 COLUMBUS REGIONAL

CMH is operated by the Columbus Regional Airport Authority (CRAA), which sets the policies under which the airport is operated. The CRAA is an independent governmental entity responsible for the operation of CMH as well as Rickenbacker International Airport (LCK) and Bolton Field Airport (TZR). The creation of the CRAA was a result of a merger between the Columbus Municipal Airport Authority and the Rickenbacker Port Authority (RPA) on January 1, 2003.

A Board of Directors is the governing body of the CRAA and is composed of nine business and community leaders. The Mayor of the City of Columbus appoints four members of the Board, the Franklin County Board of Commissioners appoints four members, and one member is appointed jointly by the Mayor and the Franklin County Board of Commissioners. All Board members serve four-year staggered terms.

2.1.2 AIRPORT ENVIRONS

The airport environs refers to the regional area that may experience broader effects from the noise of aircraft operations. The airport environs for CMH is shown in Exhibit 2-1, and depicts the area of eastern Franklin County, western Licking County, and northwestern Fairfield County, as well as the jurisdictions contained within. The map includes jurisdictional boundaries, local roads and major highways, the airport property line, and significant geographical features. The airport environs does not follow geographic boundaries, but rather encompasses an area approximately 14 by 9 miles (126 square miles). The area extends approximately four miles to the north and south of the airport, and six miles to the east and west.

The area is of adequate size to depict flight tracks and the jurisdictional boundaries used in this study.

The airport environs map extends to the Village of New Albany to the north, Pataskala to the east, I-70 to the south, and downtown Columbus to the west. The jurisdictions in the airport environs include Fairfield, Franklin, and Licking counties; Jefferson, Mifflin, and Truro townships; the cities of Bexley, Columbus, Gahanna, Reynoldsburg, and Whitehall; and the Village of New Albany in Franklin County; Etna and Lima townships and the City of Pataskala in Licking County; and Violet Township in Fairfield County.

2.1.3 GENERAL STUDY AREA (GSA) The General Study Area (GSA) is defined as the area that experiences direct overflights of aircraft at lower altitudes. The GSA was determined by examining the boundaries of previous 65 Day-Night Average Sound Level (DNL) noise exposure contours (the FAA-defined threshold for significant noise impacts), and by reviewing flight tracks of aircraft operating in the airport vicinity and/or under the control of the CMH Air Traffic Control Tower (ATCT). The GSA, shown in Exhibit 2-2, is the map used to show existing and future noise contours, as well as noise abatement alternatives in this document.

To the north, the GSA extends past Granville Road in Gahanna and to Agler Road in Columbus. To the east, the GSA extends to Franklin/Licking County border. To the south, the GSA extends past East Broad Street/State Route 16, almost to US Route 40, and to the west, the GSA extends to I-71, north of downtown Columbus.

2.1.4 EXISTING LAND USES IN THE GENERAL STUDY AREA

Land uses in the GSA were identified, mapped, and categorized in terms of the general land use classifications presented in Federal Aviation Regulations (FAR) Part 150, which includes residential (single and multi-family), commercial, public/institutional, and agriculture/open space. These uses were identified based on each county’s Geographic Information System (GIS) database (where available), previous Part 150 studies, additional land use surveys provided by the CRAA or local jurisdictions, and was supplemented as necessary by field verification. Appendix D, Land Use Methodology, provides additional detailed information regarding the classification and identification of land uses. Exhibit 2-3, depicts the existing land uses within the GSA.

The area for which existing land uses were identified involves two levels of delineation: 1) the area directly adjacent to the airport and the areas directly in line with the east/west orientation of the runways that may be affected by specific localized impacts of noise abatement measures; and 2) the regional area that may experience the broader incompatibilities of aircraft overflight and noise impacts. To the immediate east and within previous 65 DNL noise exposure contours, land uses are characterized by commercial/industrial areas, interspersed with low density to medium density residential areas. To the west of CMH, land uses are dominated by medium density residential.

2.1.5 EXISTING NOISE-SENSITIVE PUBLIC FACILITIES IN THE STUDY AREA

Land uses that could be considered incompatible with airport operations include more than just residential uses. FAR Part 150 defines certain public facilities as noise-sensitive; churches, schools, nursing homes, libraries, and hospitals. Within the GSA there are 77 schools, 232 churches, two hospitals, and five libraries as shown on Exhibit 2-4. In Appendix D, Land Use Methodology, Table D-1 discusses the methodology for collecting and organizing the noise-sensitive facility data and provides a list of all facilities.

2.1.6 EXISTING HISTORIC SITES

Within the GSA, there are five historically significant structures. One is located on airport property, the Old CMH ATCT. The other four include Air Force Plant 85 and associated facilities, Valley Dale Ballroom, the Elam Drake Residence and a house at 1388 Sunbury Road. Historic sites are shown on Exhibit 2-5, Historic Resources and listed in Table 2-1.

Air Force Plant 85 facilities built between 1940 and 1941 were determined to be eligible for listing on the National Register of Historic Places for their significance in the areas of history and architecture. The Old CMH ATCT was built in 1929 and was listed on the register in 1979 for its significance in the areas of architecture and transportation. In 1982, the Valley Dale Ballroom was listed on the register for its significance in the area of performing arts. The building constructed in 1925, was a popular performance venue during the Big Band era and hosted national radio broadcasts of performances. The Elam Drake Residence was constructed circa 1856 and listed on the register in 1978. The property, consisting of a house, barn, and outbuilding, is significant as an example of a typical farm grouping of the nineteenth century.

2.2 EXISTING LAND USE GUIDELINES/PLANNING DOCUMENTS

Neither the CRAA nor the Federal government has the authority to implement or enforce local land use policies and regulations. That responsibility falls to the local jurisdictions, which could include the county, city, or township. The Part 150 process includes a review of local comprehensive planning efforts, land use regulations, zoning ordinances, building codes, and subdivision regulations.

In most cities and counties, the chief land use regulatory document is the zoning ordinance, which regulates the types of uses, building height, bulk, and density permitted in various locations. Subdivision regulations are another important land use tool, regulating the platting of land. Local communities also regulate development through building codes and, in some cases, enforce noise regulations. The local capital improvements program, a schedule for constructing and improving public facilities such as streets, sewers, and water lines, is another important policy document that could influence development; although, on its own it does not involve regulation.

The Part 150 planning process does not propose, recommend, or fund the mitigation of future proposed development. It does, however, identify areas of potential future noise exposure for use by local planners in the development of comprehensive planning documents and land use policies. By preparing a comprehensive plan and setting land use policies, a jurisdiction or community can develop land appropriately and according to a locally accepted, approved plan. It is important that these planning efforts identify the likely development potential of land near the airport, within the published airport noise contours, or under existing or proposed future aircraft flight tracks. The local land use planning policies provide the airport sponsor with a description of the types of future development that should occur in areas not yet developed or to be redeveloped within the community.

Within the CMH GSA, six municipalities (Bexley, Columbus, Gahanna, Pataskala, Reynoldsburg, and Whitehall), Franklin County, and Jefferson Township share the responsibility for land use regulations. Summaries of the existing and future land use and zoning plans for these jurisdictions are included in Section 2.2.1 through Section 2.2.8 of this chapter.

2.2.1 AIRPORT ENVIRONS OVERLAY ZONE

The previous Part 150 Study recommended the establishment of and Airport Environ Overlay (AEO) to assist in controlling residential development within the higher noise levels resulting from airport activity. Two jurisdictions within the GSA, the City of Columbus and Franklin County, have adopted the AEO to limit development within areas that are significantly impacted by airport noise. The local ordinances are based on model regulations developed by the Mid Ohio Regional Planning Commission (MORPC) in 1991. The City of Columbus adopted the AEO in 1994 and Franklin County adopted a similar ordinance in 1996. Both ordinances added an overlay zone that established additional development standards and criteria for property within areas that are significantly impacted by noise. The AEO ordinances establish subdistricts according to the 65+, 70+, and 75+ DNL as

Landrum & Brown Chapter Two – Affected Environment November 2007 Page 2-9 PORT COLUMBUS INTERNATIONAL AIRPORT FAR PART 150 NOISE COMPATIBILITY STUDY FINAL indicated by the most recently published NEM. Within these subdistricts, land use is regulated to prevent non-compatible development that is incompatible with high levels of aircraft noise. The overlay zone boundary changes accordingly to updates to the NEM and is therefore not static. Specific regulations from each jurisdiction’s zoning ordinance regarding the application of the AEO are discussed in the following sections.

2.2.1.1 Franklin County

Franklin County administers planning and zoning within the unincorporated areas excluding Jefferson Township.

2.3 GROWTH RISK/SIGNIFICANT DEVELOPMENT TRENDS

The Central Ohio Region11 is currently experiencing rapid growth that began nearly 20 years ago. Between 1990 and 2000, the population of the Central Ohio Region grew by 15 percent, compared to a growth rate of five percent statewide.12 The population of Franklin County is projected to grow by an additional 26 percent between 2000 and 2030. Employment in Franklin County is also expected to grow by 43 percent between 2000 and 2030. The jurisdictions within the GSA are expected to experience population growth at 20 percent and employment growth at nearly 30 percent during the same timeframe. This growth is expected to be highest in the jurisdictions of New Albany and Gahanna, to the north of CMH.13 Table 2-4, Population Estimates, 2000 to 2030, and Table 2-5, Employment Estimates, 2000 to 2030, show these estimates for each jurisdiction within the GSA.

Land use in the Central Ohio Region is changing in response to the growth trend. The amount of agricultural land decreased by ten percent from the early 1980s through the late 1990s. In the Central Ohio region, Franklin County has experienced the largest share of population growth over the past 20 years. However, its share of growth is projected to decline in the coming years as the surrounding counties attract more people. Forty percent of new houses are being built outside of Franklin County in low density residential areas at the outer edge of existing urbanized areas.

Predominant land uses in the areas surrounding CMH are medium to high density residential and commercial/industrial. Future plans for the municipalities surrounding CMH include the preservation of existing residential neighborhoods and the development of new neighborhoods and associated commercial/industrial services. Future residential growth near CMH is inevitable and, if not specifically restricted through zoning, could occur in areas that receive noise in excess of 65 DNL. To the west of the airport new residential development is a combination of infill within existing neighborhoods and some limited subdivision development. Examples of the new subdivisions can be found northwest of the airport in the City of Columbus along Sunbury Road. East of the airport, particularly in Jefferson Township, large residential subdivisions are being constructed and others are planned. The closest large residential subdivision to CMH is being constructed on Taylor Station Road with plans for 485 new homes to be built. This subdivision is located just outside of the Future (2012) Baseline 65 DNL noise exposure contour.
