Home My WebLink AboutRevised Traffic Study 041921 April 16, 2021 Mr. Blake Wiggins Wiggins Family Real Estate, LLC 109 Orle Drive Little Rock, AR 72223 Re: P2076 WolfsBridge at Brookside Traffic Assessment Brookside Drive, North of Rodney Parham Road Little Rock, Arkansas Dear Mr. Wiggins: Peters & Associates Engineers, Inc. has updated the traffic assessment made in January 2021 for this tract related to what can be the expected trip-generation. It is proposed to re-zone the property to accommodate an approximate 280-unit multi-family development (WolfsBridge at Brookside). The site is proposed to be developed as MF-24 zoning on approximately 11.67 acres. The site is located along Brookside Drive, north of Rodney Parham Road, east of Reservoir Road and south of White Rock Lane in Little Rock, Arkansas. Access to the site is proposed via the connection of Brookside Drive from south of the site (via Rodney Parham Road) and to the existing Brookside Drive north of the site (via White Road Lane and Reservoir Road). EXISTING TRAFFIC CONDITIONS AM and PM peak hour vehicle turning movement counts at the intersection of Rodney Parham Road and Brookside Drive provided by the City of Little Rock were used as a baseline representation of existing traffic conditions. Although these counts are dated November 2017, per Arkansas Department of Transportation (ARDOT) published traffic volumes on Rodney Parham Road, just west of Brookside Drive have shown to have decreased since 2017 as follows:  2017 ARDOT Average Daily Traffic (ADT) = 34,000 vehicles per day.  2018 ARDOT ADT = 26,000 vehicles per day.  2019 ARDOT ADT = 26,000 vehicles per day. These data are all pre-COVID, so likely are representative of 2021 (and post-COVID) conditions. TRIP GENERATION The Trip Generation, an Informational Report, published by the Institute of Transportation Engineers (ITE) and The Trip Generation Manual 10th Edition, 2017, were utilized in calculating the magnitude of traffic volumes expected to be generated by full build-out of the proposed land-use of 280 multi-family residential units on this site. These are reliable sources for this information and are commonly used in the traffic engineering profession. Results of these calculations are summarized on Table 1, “Summary of Trip- Generation – WolfsBridge at Brookside.” WolfsBridge at Brookside April 16, 2021 Page 2 24-HOUR TWO-WAY AM PEAK HOUR PM PEAK HOUR APPROXIMATE ITE WEEKDAY VOLUME VOLUME LAND USE SIZE CODE VOLUME ENTER EXIT ENTER EXIT Multi-Family Residential 280 Units 220 2,050 30 99 99 58 157TOTAL ENTERING + EXITING 129 Table 1 – Summary of Trip Generation - WolfsBridge at Brookside The calculations indicate that approximately 2,050 vehicle trips (combined in and out) per average weekday are projected to be generated by the proposed land use on this site. Of this total, approximately 129 vehicle trips are estimated during the traffic conditions of the AM peak hour and approximately 157 vehicle trips are estimated during the traffic conditions of the PM peak hour. In 2001, the City of Little Rock Planning Commission and Board of Directors approved a rezoning of this property from R-2 and O-3 to "PRD" Planned Residential District (Ordinance No. 18,593). The PRD was approved to allow an independent living apartment facility including a 210,000 square foot four (4) story building with 190 parking spaces. The building was to contain 126 apartment units. The plan also included 15 independent living villas along the east portion of the overall property. This PRD project was never developed. Calculations were made to provide a reliable estimate of traffic volumes that could have been expected to be associated with the 2001 approved PRD as proposed. Results of these calculations are summarized on Table 2, “Summary of Trip-Generation – Previously Approved 2001 PRD.” 24-HOUR TWO-WAY AM PEAK HOUR PM PEAK HOUR APPROXIMATE ITE WEEKDAY VOLUME VOLUME LAND USE SIZE CODE VOLUME ENTER EXIT ENTER EXIT Senior Adult Residential (Attached) 126 Units 252 466 9 16 18 15 Senior Adult Residential (Detached) 15 Units 251 64 1 3 3 2 530 10 19 21 17 TOTAL ENTERING + EXITING 29 38 2001 PREVIOUS APPROVED PRD TOTAL DRIVEWAY VOLUMES Table 2 – Summary of Trip Generation – Previously Approved 2001 PRD These calculations indicate that approximately 530 vehicle trips (combined in and out) per average weekday would have been projected to be generated by the previously approved PRD land uses on this site. Of this total, approximately 29 vehicle trips are estimated during the traffic conditions of the AM peak hour and approximately 38 vehicle trips are estimated during the traffic conditions of the PM peak hour. Traffic to/from the proposed WolfsBridge at Brookside site is expected to be split between the proposed connection of Brookside Drive from south of the site (via Rodney Parham Road) and to the existing Brookside Drive north of the site (via White Road Lane and Reservoir Road). Directional distribution percentages used in this study are shown on the following figure, “Directional Distribution - Site Traffic.” WolfsBridge at Brookside April 16, 2021 Page 3 Directional Distribution – Site Traffic WolfsBridge at Brookside April 16, 2021 Page 4 PERCENT CHANGE TO INTERSECTION There difference in vehicles entering the intersection of Rodney Parham Road and Brookside Drive during the AM and PM peak hours has been compared for existing traffic conditions and for projected traffic conditions that includes the completion of the proposed WolfsBridge at Brookside, shown as follows: 2648 2734 2000 2500 3000 Existing With ApartmentsAM Peak Hour Total Entering VolumeRodney Parham Road and Brookside Drive AM Peak Hour Total Entering Traffic Volume 2458 2569 2000 2500 3000 Existing With ApartmentsPM Peak Hour Total Entering VolumeRodney Parham Road and Brookside Drive PM Peak Hour Total Entering Traffic Volume WolfsBridge at Brookside April 16, 2021 Page 5 The comparison graphics of the difference in total vehicles entering the intersection of Rodney Parham Road and Brookside Drive during the AM and PM peak hours show, for existing traffic conditions and for projected traffic conditions, which includes the completion of the proposed WolfsBridge at Brookside, the percent increase of traffic at the intersection of Rodney Parham Road and Brookside Drive is only 3.3 percent during the AM peak hour and only 4.5 percent during the PM peak hour. This is a small change in traffic volume, even for the peak hours. With the low increase in traffic volume at the intersection of Rodney Parham Road and Brookside Drive during the AM and PM peak hours, there is expected to be minimal impact to traffic operations at this intersection if the development is constructed as proposed.
