BRUNSWICK COUNTY THOROUGHFARE PLAN PROJECT OBJECTIVES A county thoroughfare plan enables the County goverment to become actively involved in the selection of improvements and new construction of its highways. This plan,if adopted by the Department of Transportation and Highway Safety, will become an active part in the states comprehensive transportation plan for Brunswick County. A thoroughfare plan should be based on present and projected traffic volumes, topography, land-use, location of major traffic generators, ar.igin-destination data, and other related consideration of mass transportation The objectives of this plan are: 1) Develop short range, high priority rights-of-way 2) Develop priorities for county road improvements 3) Develop priorities for new road construction 4) Develop association between adopted land use plan and transit priorities.

Unless people and materials can move easily from place to place an area will not develop to its potential. Streets, roads and highways are our links between these places. Realizing the key that these play, it becomes increasingly necessary to develop a good system to handle the present and future needs. This Thoroughfare Plan is designed to provide a network of roads which will help to guide Brunswick County's growth into the early 1980s'. The proposed improvements presented in this plan will become a part of the State's Road Improvement Plan for Brunswick County. It is important to remember that this is a general plan and will require updating periodically. This plan is designed to be a guide for future decisions, BRUNSWICK COUNTY 00 rV Al J_w x1- ep THOROUGHFARE PLANNING PRINCIPLES There are many benefits to be gained from thoroughfare planning. But the major objective is to assure that the road system is adequately developed to serve future travel desires. The Department of Transportation cites two major benefits derived from thoroughfare planning. 1) Each road or highway can be designed to perform a specific function and to provide a specific level of service. 2) Local officials are informed as to future improvements. Both of these allow for logical development. Construction costs can be cut, school and park officials can better locate their facilities, money can be saved in purchasing rights-of-way, developers can design subdivisions to function in a non-conflicting manner and there are many other benefites. Streets, roads and highways serve two areas. First they provide mobility for the traffic which flows on them. Second they provide the adjacent land with access. These two factors become increasingly incompatible as there intensity increases. Congestion is the result. The underlying concept of this thoroughfare plan is to provide a functional system of streets, roads and highways which will allow travel with ease and safety, thus minimizing the conflict between the traffic and the land. 2 COUNTY THOROUGHFARE CLASSIFICATION SYSTEM The rural or County system consistsof roads, streets and highways which are outside of urban planning boundaries. These facilities are classified into four categories: PRINCIPAL ARTERIALS: These provide a network of continuous routes which serve corridor movements having trip lenths and densities of statewide or interstate travel. This system should serve all urban areas of over 50,000 population and a majority of those of 5,000 or greater population. MINOR ARTERIALS: These provide a network which link cities, large towns, or other major traffic generators such as beach resorts. This system generally serves intercounty and interstate travel. These are designed for shorter trip lengths and smaller densities than principal arterials. COLLECTOR ROADS: The collector roads serve primarily intracounty trips. This system is subclassed into- Major Collectors: These routes provide service to the larger towns not served by the higher systems. It also links such traffic generators of intracounty importance such as shipping points, county parks, mining or agricultural areas, etc. They are also used to link smaller towns with larger cities and generally serve as the most important intracounty travel corridors. Minor Collectors: These routes are used to bring all developed areas within a reasonable distance of a major collector. They are also used to connect local important traffic generators with the rural hinterland. LOCAL ROADS: The local roads comprise all roads not described in one of the above. Ex: Subdivision streets, cul-de-sacs, etc. This Chart shows the average percentage of all county rural miles that each system participate.

Using pavement width, number of lanes, the A.D.T. counts, and capacity figures supplied by the Department of Transportation, percentages of capacity use were calculated for both 30 and 55 miles per hour. The following charts show these calculations for Brunswick County's major roads. 5 C:- C. C-_ jc-- cz c-, I-- F- i= C/-) @n c 4- @.A -C!:, co %-n CD rl.) llo rl.)

In areas where accidents are frequent, it can be concluded that the road is dificient in design. Combining the sections of roadways which are dangerous in design with sections which are operating above 100% capacity, results in what should be considered top priority situations for road improvement. The following chart shows the high accident locations for 1976 and 1977. 1976 HIGH ACCIDENT LOCATIONS ACCIDENT EXPECTED ROUTE NUMBER LOCATION RATE/YEAR RATE N.C. 133 Intersection 12.61 177.75 SR 1529 U.S. 17 US74-76 and N.C. 133 3.46 13.75 U.S. 74-76 SR1435 - SR1437 1.90 10.53 U.S. 74-76 SR1462 - SR1472 2.41 14.62 1977 HIGH ACCIDENT LOCATIONS ACCIDENT EXPECTED ROUTE NUMBER LOCATION RATE/YEAR RATE N.C. 133 SR1529-SR1529 12.76 111.74 6 HIGH ACCIDENT LOCATIONS BRUNSWICK COUNTY 1c-17G 1977 74-76 \%% 7 211 The Department of Transportation continually implements an improvements program.

The Average Daily Trips or average number of vehicles which use a road on a particular day; the calculated capacity of a particular road and the percentage of that capacity which is being filled; and high or frequent accident locations. We can postulate that as any one of these three indicators increase a subsequent increase willoccur in the other two. In reality, as trips increase, the design capacity nears 100%, and the actual and expected rates of accidents also increase. In Brunswick County five primary routes are operating at above 100% capacity. 1) U.S. 17 which is a principal arterial. Its average capacity is 2700 vehicles, and its average daily travel count is 9600. It is operating overall at 281.25%. This is 181.25% above what U.S. 17 was designed for. 2) U.S. 74-76 which is a minor arterial. Its average capacity is 3,760 vehicles/day. Its average daily travel figure is 10,462. It is operating at 360%. This 260% above its design capabilities. 3) N.C.133, which is a minor arterial. Its average capacity is 2,314 vehicles/day. Its average daily traffic count is 4,576. It is operating at 199%. This is .99% above its designed capacity. 4) There are two sections of N.C. 130 which are deficient in design. These two are sections were designed for 2,100 cars/day. The ADT figure is 3,393. These sections of roadway are operating at 161.5% or 61.5% above their design capacity. 5) There are also two sections of N.C. 904 which are operating at above 100% capacity. N.C. 904 is a collector road. Its ADT count is 2,535. Its average design capacity is 2100. It is operating at 20.7% above design capabilities. 13 The high accident locations are found, as we could have postulated, on routes operating at above 100% capacity. There are four major areas which the Department of Transportation considers high risk for Brunswick County. The number one area is located on N.C. 133 at the intersection of SR1529. This is the access road to Orton Plantation. It is complicated by a severe curve and a bridge. The accident rate for this area in 1977 was 12.76/year, the expected rate was 111.74. The number two risk area is on U.S. 74-76 at the intersection of SR's 1462 and 1472. The 1976 accident rate was 2.41/year with an expected rate of 14.62. The third major area is on U.S. 17 at the intersection of U.S. 74-76 and N.C. 133. The 1976 accident rate was 3.46 and the expected rate was 13.75%. Number four is also located on U.S. 74-76. T@e accident location is at the intersection of SR's 1435 and 1437. The 1976 accident rate was 1.90 and the expected rate was 10.53. In formulating a plan for future transportation needs we must first deal with these existing deficiencies. 14 THE THOROUGHFARE PLAN This plan, if adopted by the Board of County Commissioners of Brunswick County and by the Department of Transportation, should become a part of the States overall transportation improvement plan for Brunswick County. SHORT RANGE GOALS 1. The top priority is to eliminate the areas identified as overcrowded and accident prone. It is therefore proposed that N.C. 133 be upgraded to a minor arterial with a design capacity of 4,000 vehicles/day. This proposal includes widening, straightening curves and resurfacing from the inter- section of N.C. 87 to the intersection of U.S. 17. (P.1 of Map) 2. Upgrade U.S. 17 in accordance with the States 1990 functional plan. This project is funded and has a tenative completion date of 1985. (P. 2 of Map) 3. Upgrade U.S. 74-76 also in accordance with the State's 1990 functional plan. This project is already funded and near completion. (P. 2 of Map) 4. Upgrade N.C. 211 from Southport to SR1500 at Smith to design capacity of 3,000 vehicles/day. (widen existing two lane increase shoulder resurface), (P. 3 of Map) 5. Upgrade N.C. 211 from Supply to Columbus County line to design capacity of 3,000 vehicles/day. (widen existing two lanes, increase shoulder resurface). (P. 3 of Map) 6. Upgrade SR1500 from Smith at N.C. 211 to Bolivia at U.S. 17 to a major collector. (Resurface, straighten curves, increase shoulder upgrade to 2,000 vehicles/day design. (P. 4 of Map) 7. Resurface SR1112 from N.C. 211 to Sunset Harbor, SR115 from Supply to Holden Beach City Limit, N.C. 130 from U.S.17 at Shallotte to Holden Beach City Limit, and N.C. 904 from Grissettown to Gause Landing.

This proposal is parallel to the State's 1990 functional plan. The East-West link will begin at N.C. 133 at Yaupon Beach, upgrade Oak Island Drive to a major collector to the end of Oak Island, construct a bridge linking Long Beach with SR 1119 across Lockwoods Folly Inlet. From there continue the major collector to N.C. 130, follow N.C. 130 to SR 1139, to SR 1137, to SR 1138. At that point, construct a bridge from the end of SR 1138 to Little Beach across the Shallotte Inlet. From there continue the major collector on SR 1155 to SR 1156, to N.C. 904 in Gause Landing. The follow N.C. 904 to SR 1163 and on to the South Carolina State Line. 16 BDUNSWICK COUNTY RIOROUGHFARE PLAN LONG R91GE GOALS PROPOSED ROUTE PROMSED BRIDGES IMPLEKENTATION This Thoroughfare Plan must first be adopted by the Brunswick County Commissioners. The Commissioners must then request the State Highway Commission to review the Plan. They make their recommendations and if both approve, the Plan becomes a part of the States development plan for Brunswick County. Actual construction of these proposals is contingent upon the availability of funding on the State and Federal levels. Brunswick County has two effective tools it can use to help the successful implementation of this plan. A) Subdivision Controls: Through subdivision regulations every subdivider is required to submit his plan for proposed streets. The district engineer has an oportunity to comment on the proposed design. The Planning Board also has the opportunity to insure that the plan conforms with the Thoroughfare Plan so that construction of subdivision streets meets the State's standards. This reduces maintenance cost and facilitates easy transfer of the streets to the State system. B) Zoning Regulations: The County has the opportunity to use zoning regulations along with the adopted Land Use Plan to insure appropriate development along r,o:ads and highways. The zoning ordinance can improve highway safety by requiring sufficient setbacks for buildings,to provide adequate sight distances, and to provide for off-street parking. 17 ENVIRONMENTAL ASSESSMENT The road construction proposals presented in this plan will have no adverse environmental effects. This is due to the fact that existing rights-of-way and existing roadways will be used for all improvements with the exception of the bridge construction in the long-range proposals. Pursuant to the adoption of the Coastal Area Management Act, the proposed bridge construction lies in an Area of Environmental Concern. This is not to say that construction is eliminated from this area, but it should be noted that it could possibly be necessary for a major permit application to be filed with the Coastal Resources Commission. Should a construction permit be granted, strict procedures to preserve the inlet structures and migration patterns should be adhered to. 3 6668 14100 6678
