INTRODUCTIONDeShazo Group, Inc. (DeShazo) is an engineering consulting firm providing licensed engineers skilled in thefield of traffic/transportation engineering. The services of DeShazo were retained by Masterplan on behalf ofthe Dallas Independent School District (DISD) to prepare an update of the Traffic Management Plan (TMP) forthe Nathan Adams Elementary School (the School) located at 12600 Welch Road in Dallas, Texas.
The School has a current enrollment of approximately 554 students in Pre-Kindergarten through 5th grade.Student population is anticipated to grow up to 610 students in the upcoming school years. The schooladministration is also planning a revision to the site plan previously approved by City Plan Commission. Theproposed changes will include site improvements to accommodate additional off-street parking spaces andon-site drop-off/pick-up areas for lower grade students. The attached site plan depicts these proposedmodifications.
The school site is zoned R-10(A) for Single-Family Residential District. In order to gain entitlements for theproposed improvements, the school administration is seeking approval for the proposed changes. As part ofthe approval process, the City of Dallas requires submittal of a TMP update as a record of the preferredtraffic control strategies and to ensure overall traffic safety and efficient operations.
This report contains DeShazo’s review of the current traffic conditions on and around the school campus aswell as an evaluation of the proposed conditions. The plan is intended to assess anticipated traffic conditionsduring the School peak activities. By consent of the TMP submittal, the school agrees to the strategiespresented herein. The school is held self-accountable to enforce the plan until and unless the City of Dallasdeems further mitigation measures are necessary.
[NOTE: In this report the term “parent” refers to any parent, family member, legal guardian, or other individual who isinvolved in the pick-up or drop-off of one or more students at the school.]

TRAFFIC MANAGEMENT PLANA school TMP is important to safely achieve an optimum level of traffic flow and circulation during peaktraffic periods associated with student drop-off and pick-up operations. By properly managing the vehiculartraffic generated during critical periods, the safety and efficiency of school carpool operations will alsoinherently improve. This TMP should not be considered a comprehensive set of instructions to ensureadequate safety; however, it is a tool that aims to facilitate a safer and more efficient environment.
The analysis summarized below identifies the projected vehicle demand—including parking and queuingspace (i.e. vehicle stacking)—needed on site to accommodate projected school traffic demands during peakperiods. A concerted effort and full participation by the school administration, staff, students and parents areessential to maintain safe and efficient traffic operations. The use of designated parking and queuing areas isnecessary to minimize the operational impact on adjacent properties and the public street system.
School Operational CharacteristicsDeShazo conducted field observations of the school on Thursday, December 17, 2015 during all studentdismissal periods. Table 1 summarizes the operational characteristics for DISD Nathan Adams Elementary atthe time of these observations.

NOTE #1: Occasional functions or other events may be held at the school, which generatetraffic outside of the traditional peak drop-off and pick-up periods. While some of themeasures presented in this report may be applicable in such cases, traffic characteristicsother than those directly associated with the primary drop-off and pick-up periods are notthe subject of this analysis.
Site Access and CirculationThe subject site provides a small parking area for faculty and staff, which is accessed from Harvest Hill Road.However, no off-street area is available for student loading and unloading—all traffic activities take placewithin public right-of-way. In order to accommodate the school’s traffic demands during peak periods,parents line up and queue in the perimeter of the school property and wait for students to be dismissed. Atotal of three school buses load students on the curb immediately in front of the school on Welch Road. Theproposed school renovations include a new on-site parking lot with approximately 30 spaces and a drivingaisle accessed from Harriet Drive with enough queuing capacity for up to 14 vehicles.

Passenger Unloading/Loading and Vehicular QueuingDuring the afternoon pick-up period, the majority of students are transported by parents in personalvehicles. The school provides loading areas along the perimeter of the school. Most parents choose to parkon adjacent streets and walk to greet their child(ren) on-site. Field observations indicate a maximum total ofapproximately 95 vehicles present during the afternoon student dismissal period. The maximum queue,however, was only evident for no more than 10-15 minutes at that time.
DeShazo’s school observations consistently indicate that maximum queues occur during the afternoon peakperiod when students are being picked-up—the morning period is typically not a significant traffic issue sincedrop-off activities are more temporally distributed and occur much more quickly than student pick-up. Ingeneral, the same operation is in effect during the morning peak period; however, the overall volume ofvehicles is less concentrated than the afternoon peak hour volume. The evaluation of the traffic in this reportis thus based upon the afternoon pick-up period.
RecommendationsExhibit 1 presents the proposed traffic management plan that requires full enforcement of student drop-off/pick-up queue operations. The following set of traffic operations are also recommended for NathanAdams Elementary School during peak traffic conditions:
Traffic Queue Operations• Traffic circulates clockwise around the perimeter of the school during both the morning and afternoon
school peak periods; queues lead traffic to their respective loading/unloading areas.
• As shown on Exhibit 1, a total of 966 linear feet (in addition to the new proposed parking lot) provideenough capacity for a projected maximum queue of 27 cars for students in Pre-Kindergarten andKindergarten. In addition, a total of 1,200 linear feet (enough capacity for a queue with up to 51 cars) isexpected to accommodate the needs of the projected queue for the remaining students in1st_5th grade.
• During the afternoon pick-up period, the school should implement a “Passenger Identification System”.The school should issue hangtags to parents with unique identification that pairs them withcorresponding student(s) at the beginning of each school term. Hangtags must be on display throughthe vehicle’s windshield while parents arrive at the pick-up areas during pick-up periods. School staffshould also be positioned at strategic locations ahead of the loading area and relay the sequence ofarrivals via hand radio while students are prepped for pick-up. With the assistance of other school staffstationed at the loading area, several vehicles should be loaded simultaneously. After each loading,vehicles should be cleared by school staff to carefully exit the queue.
Proposed New Parking Lot Operations
• The access to the proposed parking lot on Harriet Drive should not be aligned with Harriet Circle;driveway will include a raised median (or “pork-chop island”) to allow right-in/right-out access only.
• Pick-up and drop-off operations for Pre-Kindergarten and Kindergarten students should be concentratedat the new proposed parking lot on Harriet Drive. In addition, school should designate this area forfamilies with multiple students at Nathan Adams Elementary.
• Families with multiple students at Nathan Adams Elementary should also be guided towards the newproposed parking lot (on Harriet Drive) to minimize the number of vehicles that require longer waitingtimes and maintain a continuous flow of queue operations on Welch Road.

School Bus Operations
• DeShazo recommends the relocation of all school bus loading activities to the designated bus zone onHarvest Hill as shown on Exhibit 1. This TMP provides a designated pedestrian path to therecommended zone for school bus activities. It also results provides a student loading/unloading zonefor drop-off and pick-up queue along the northbound lane (west curb) of Welch Road.
Enforcement
• School officials should appoint a safety committee whose objective is to implement actions of this TMPand make any necessary adjustments necessary to enforce a coordinated traffic management plan.
• At the request of the school and neighboring property owners, traffic signs should restrict schoolparking, standing or unattended vehicles on the westbound lane (north curb) of Harvest Hill as well asthe eastbound lane (south curb) of Mill Creek. NOTE: These signs are not depicted on Exhibit 1.
• To better organize traffic operations and discourage on-street parking across Welch Road during pick-uppeak hours, parents arriving southbound on Welch Road should be encouraged to turn left onto HarvestHill Road and proceed to systematically drive around the School perimeter towards a pick up location oftheir choice—effectively creating a one-way, clockwise flow around the school property. Thisrecommendation can be further encouraged with City approval by:
o installing “NO PARKING/STANDING” signs on the southbound segment of Welch Road directlyacross the school property;
o removing all “NO PARKING” or idle time restriction signs on the northbound segment of WelchRoad directly in front of the school property;
o encouraging parents not to park in front of residential properties west of Welch Road; and,
o Installing traffic signs that restrict unattended vehicles and encourage an active queue circulation.
• At least one school employee should continue to patrol student dismissal at each of the schoolbuilding’s main access points. At least one school staff should guide students towards the proposed on-site queue and direct vehicles to egress along the by-pass lane. Likewise, at least one school employeeshould patrol students headed towards the bus loading station.
• At the discretion of City staff, the existing pedestrian crosswalk on Welch Road at Laren Lane should beremoved, if possible, to discourage mid-block pedestrian crossing.
• The proposed traffic plan will guide parents around the school block and potentially createopportunities for pedestrian traffic across Harriet Drive. Given this consideration, DeShazo recommendsthe installation of school zone signs in the vicinity of the intersection of Harriet Drive and Mill CreekRoad, at the discretion of the City of Dallas Department of Street Services.
• However, to minimize liabilities, the School should allow no school staff other than DISD police and/ordeputized officers of the law to engage or attempt to influence traffic operations in public right-of-way.
• As needed, staff directing dismissed students out of the school building should, in lieu of simple handgestures, procure and use reversible hand-paddle signs with the messages for STOP and SLOW. Optionaladditional equipment used by staff may include whistles (for audible warnings) and fluorescent vests(for visual warning).

The proposed traffic management plan requires full enforcement of student carpool operations and assumesthat only a minimal amount of parents choose to park and walk into the school building. It also assumes thatall involved/interested parties understand and agree to the following traffic operations—particularly to theamount of traffic directed along Harriet Drive.
SUMMARYField observations of existing conditions indicate that student loading/unloading activities operate withoutany severe problems. A number of recommendations are provided in this report for consideration by DISDand school officials. Full cooperation of all school staff members, students, and parents is crucial for thecontinuing success of any traffic management plan. The referenced TMP should be enforced by DISD NathanAdams Elementary School to provide safe and efficient transportation of students, staff, and faculty to andfrom the site. The plan was developed with the intent of optimizing safety and efficiency and the goal ofaccommodating within the site vehicular traffic generated by the school at peak traffic periods. The schoolshould review details of this plan on a regular basis to confirm its effectiveness.
