HomeMy WebLinkAboutletter from Peters to McCray on traffic numbersJuly 2, 2001 Mr. Jack McCray Chenal Properties #7 Chenal Club Blvd Little Rock, AR 72211 Bus: (501) 821-5757 Bus Fax: (501) 821-5656 Dear Mr. McCray: As you requested, we have examined the traffic conditions, associated with proposed land use changes to the Chenal Properties land use plan, which can reasonably be expected in the vicinity located between Chenal Parkway, Rahlings Road, Chenal Valley Drive and Taylor Loop Road. The land use changes proposed call for reductions in intensity, such as from multi -family to single family, and from commercial to single family. These changes will have the net effect of reducing the future traffic demand on the existing arterial street network. The only existing City Master Street Plan (MSP) arterial route through the area is one shown (but not platted not built) to route from the north (future) intersection of Chenal Parkway and Chenal Valley Drive (a collector) to the west portion of Taylor Loop Road (which connects to Highway 10). This planned route is shown on Exhibit 1, "Existing Master Street Plan." This arterial was not even considered as a connecting route in the 1995 Chenal Parkway Corridor Study, but the traffic projections associated with the more intense land uses, now proposed to be reduced, were included as contributing to Chenal Parkway future volumes. The route shown on the MSP is one which is not essential as a part of the arterial network, nor will it be necessary to support the proposed land uses in the vicinity. The proposed land uses can properly be served with a collector route (La Marche Boulevard) extension (already on MSP as a collector) to another unnamed collector (also already on MSP as a collector). This unnamed collector is shown on the MSP as connecting to the south loop of Taylor Loop Road (already on MSP as a collector) which logically should continue west via its existing connection to Highway 10, as a collector. This revised MSP configuration is shown on Exhibit 2, "Proposed Master Street Plan." Traffic volumes which are projected to occur on the La Marche Boulevard and unnamed collector routes are consistent with MSP service volumes (MSP calls for a service volume of 5,000 vehicles per day on collectors) for such classified streets. The Level of Service "C" on such collectors can be maintained at even higher volumes, in the range of 11,000 to 13,000 vehicles per day. The total traffic volume projected to be generated by land uses which would be served by the proposed MSP collector routes is less that 7,000 vehicles per day. This data is included on the "Trip Generation" table attached. This volume would be shared on both La Marche Boulevard and the unnamed collector and would be somewhat distributed in both directions, resulting in actual likely service volumes on these routes of no more than approximately 3,000 vehicles per day. Such low volumes could obviously support even additional vehicle demands from outside the area which might choose the collectors as "cut through" streets, but this would be discouraged by there being no direct connecting route and other traffic -calming measures such as roadway curvature, "T" intersections, etc. We conclude the proposed changes to the street network coupled with the reductions in land use intensity (as suggested as possible mitigative action in the 1995 Chenal Parkway Corridor Study) are appropriate and without adverse impact on the MSP street network. Please let me know if there are any questions concerning this matter. PETERS & ASSOCIATES ENGINEERS, INC. Ernest J. Peters, P.E.
