TRAFFIC ANALYSIS REPORT Revised February 15, 1993 PROPST PROPERTY DEVELOPMENT PLAN Sarah W. LaBelle Transportation Planner The planned development for the Propst property includes parcels of different land uses which will significantly impact traffic flows on the surrounding road systems. AlthouEh this analys~s is based on a maximum build-out condition which would extend over a long period of time, it is necessary to consider possible current and future needs for existing road improvement, expansions and new road links. Trip generations for each of the two parcels in the development were calculated using the Institute of Transportation EnEineers (ITE) Trip Generation manual, 4th EditJono The different land use categories include R-15 (single family residential) and I-1 (light industrial) each with a list of restricted land uses. It is not known at this time what types of industry will be created in the I-1 parcels, as the variety of listed uses has a great range of traffic impacts. What follows is a brief description and weekday trip generation of each land use category. The revised development plan would permit 468 single family residential lots in parcel A, the north section of the property. Each housing unit is averaged at 8 trips/day yielding approximately 3744 for the subdivision. The Hght industrial parcel is located in the southern half of the development and totals to 322.49 acres. Zoning reEulations limit the buildable area of this parcel to 50% of the total (includes parking area). Trip generation rates are based on 161.23 acres. An average of 2.3 employees per 1000 sq/ft were calculated with a trip/weekday rate between 1.5 and 4.4. This yields a range of 10,696 to 31,484 trips per-week day with an average of 16,153. At maximum build-out, the revised Propst property development plan would yield between 14,440 and 35,228 trips/weekday with the most likely number being around 19,897. Trips will be distributed along Concord Farms Road which is the "spine" of the development; Weddington Road and US29. In the future a major access to the site will include the proposed Westside Bypass. Trip distributions/calculations were not made for this road system as no construction date has been determined. Figures 1 through 4 show the trip distributions by total numbers as well an by percent. NCDOT traffic projections are based on existing land use zoning. The traffic projections calculated for the proposed development reflect the change of zoning, showing the difference in impact for the road system. For example, if Average Daily Traffic (ADT) under current zoning is 10,000 for a road and with the proposed development it is 16,000 then the impact would be the difference of 6,000. A summary of the traffic impact, including recommendations, by each road is as follows: US29 The design capacity of this road is 50,000 trips/day with a current average daily traffic (ADT) of ]5,500. The percent capacity at this rate is 31%. The ADT is projected to be at 42,900 or 86% capacity by the design year 2020. Based on the revised traffic generations projected for this proposed development, nearly 100% of the industrial traffic will use US29 to access the property (it is recognized that there will be some degree of leakage to Weddington Rd. however, this
