Re Crescent Heights Residential Development—Pedestrian Connections to the Marq and Bicentennial Park
Dear Mr Hogue
Per your request,we have reviewed the preliminary site plan for the Crescent Heights Residential Development
as well as the latest site drawings for the Marq development with respect to pedestrian connectivity Based on
our review, we have the following comments. The comments are numbered for ease of reference and do not
imply any ranking.
1 There are two driveways for the Marq present in the latest civil drawings provided by the City of
Southlake The proposed Crescent Heights connection to Shady Oaks Drive is opposite the
southernmost Marq driveway
a. A pedestrian path from the sidewalk along the east side of Shady Oaks to the Marq entrance
area is shown on the south side of the southernmost driveway
2 Crescent Heights will likely generate pedestrian demand seeking to access Bicentennial Park and the
Marq The number of pedestrians crossing Shady Oaks is likely to be low because the entire
development consists of fewer than 60 homes
a Pedestrians from Crescent Heights would be unlikely to travel over 500 feet south,to FM 1709,
cross Shady Oaks at the traffic light, and then proceed back north over 500 feet, uphill,to the
Marq in order to cross Shady Oaks. Travel time to and from the FM 1709 signal for a pedestrian
would be likely be 4-6 minutes.
b The largest amount of pedestrian demand in the vicinity of the Marq and the Crescent Heights
development will be at the southernmost Marq driveway where the Crescent Heights street
connection to Shady Oaks is proposed
c. Turning traffic at this location will be primarily orientated to and from the south,towards FM
1709 As such, it would be desirable for pedestrians to cross on the north side of the
intersection to minimize conflicts.
I An ADA ramp and connection from the sidewalk to Shady Oaks should be provided on
both sides of Shady Oaks on the north side of the southern Marq driveway
d NCHRP report 562 provides guidelines for treatments at unsignalized pedestrian crossings
Marked crosswalks, signage, and higher levels of traffic control not recommended until
pedestrian demand exceeds 20 pedestrians per hour
e While a pedestrian demand of 20 per hour appears unlikely to be generated by less than 60
homes,if a pedestrian volume of 20 per hour is assumed,and the year 2025 peak hour volumes

from the TIA are used for Shady Oaks Drive, the crossing treatment suggested by the NCHRP
562 guidelines at this location would be a marked crosswalk only
i Active crossing treatments such as rectangular rapid flashing beacons would not be
necessary based on the guidelines due to the low speeds, short crossing distance and
likely traffic volumes at this location
ii Monitor pedestrian and vehicular volumes as Crescent Heights and the Marq begin
full operations. If conditions change in the future the City may reassess the need for
additional crossing treatments.
If you have any questions,please contact me or Jody Short at(972)248-3006 We appreciate the opportunity to
provide traffic engineering services to the City of Southlake and are available to address any additional comments
or concerns.
