RE: Traffic Impact Study – Point by Point Letter
Mitchell Property Warehouse
TIA 63502021, version 2
T/C 3762
Dear Mr. Rawls:
We are addressing you August 11, 2022 comments with this point-by-point response letter.
•Trip Generation (ITE land use subcategory): It is our understanding that
Chesapeake Real Estate Group is proposing a non-sort facility. Please
confirm for trip generation purposes.
We confirmed that the developer is proposing non-sort fulfillment warehouse uses
(ITE land use code 155). The developer updated the site plan to state the non-sort
fulfillment warehouse use, reduced car and trailer parking, and corrected the
maximum employee shift. In a letter dated August 16, 2022, MDOT SHA concurs
with the ITE land use 155 trip generation (see attached letter).
•MD 543 @ MD 7: Exhibit 2A Lane Configuration shows a double right turn
from westbound MD 7 onto northbound MD 543 but this improvement is not
part of James Run Phase I improvements and has not been bonded. This
improvement should be removed from the study.
double right turn movement from westbound MD 7 onto northbound MD 543
The
was removed from the updated traffic impact study. Traffic Concepts does not have
trip generation information that coincides with the phasing plan attached to the James
Run Site Plan Approval, therefore we have included the full build out of James Run in
the background traffic condition. The Mitchell Farm developer will construct the
subject improvement prior to the issuance of the first use & occupancy permit for the
non-sort fulfillment warehouse, in the event that the James Run developer has not
bonded the stated improvement.

• MD 159 @ Canning House Road: Harford County concurs with the MDOT
SHA comment regarding the labeling of this intersection on Exhibits 2B, 3B
and 7B. The intersection #18 label in the line diagram should be replaced by
labels for intersections #18a and #18b in the figures to correspond with the
volume figures.
The exhibits 2B, 3B, and 7B will be revised as requested.
• Diverted Trips: The study refers to Exhibit 7C identifying diverted traffic
volumes. However, there isno Exhibit 7C provided in thestudy.
Exhibit 7C is provided with attached revised traffic study. Please note that the
diverted trips shown on Exhibit 7C are included in the final analysis. This
correction does not impact the study conclusions.
• Proposed Road Connection: In the Future Condition section of the study,
two-thirds of the outbound existing peninsula trips from Canning House
Road and MD 159, and all the proposed new trips from the site are diverted
onto the new road - Canning House Extended. Justification has not been
provided for diverting this amount of the outbound existing and new traffic.
We diverted the trips onto the extended Canning House Road under the
assumption travelers will use the newly constructed commercial road. This new
roadway will not have any residential driveways and the proposed intersection at
Chelsea Road has left and right turn lanes along Canning House Road. In
addition, signage will be provided to direct motorists to utilize Canning House
Road Extended to reach MD 159.
•MD 159 @ Chelsea Road: The existing lane configuration for northbound
ChelseaRoadshownonExhibit2Bisincorrect.Theapproachshouldbe
shown and analyzed as one northbound left turn lane and one northbound
through lane
.
We agree that is the way the lanes are striped and have revised the study
accordingly. A conceptual mitigation plan for this intersection is included in the
attached revised TIS.
• MD 159 @ Chelsea Road: The mitigation identified at this failing intersection
is to monitor the intersection during buildout and install a traffic signal if
warranted and approved by MOOT SHA. If the signal isn't warranted, other
mitigation options must be considered and identified in the study.
Traffic Concepts performed a complete traffic signal warrant analysis for this
intersection, which is included in the attached revised TIS. As noted in the analysis, a
traffic signal is warranted at this intersection with the full build out of the proposed
development.

In order to alleviate any concerns that MDOT SHA may have regarding this
intersection, the Developer agrees to prepare an updated traffic signal warrant analysis
after occupancy of each building. If the analysis shows a traffic signal is warranted, the
Developer will design and install the traffic signal upon MDOT-SHA and Harford
County approval.
If the installation of a traffic signal is not approved by MDOT SHA, the County
will require other mitigation options. As such, the Developer’s alternative
mitigation plan is to construct
a Maryland T intersection. The undue delay at this
intersection is the left turn movement from northbound MD 159 onto Chelsea Road.
The proposed Maryland T improvement mitigates the delays to acceptable level of
service. The level of service results and conceptual mitigation plan are provided in the
revised TIS.
• MD 159 (Perryman Road): Explain the diverted trips from northbound
MD 159 on exhibit 11B. Trips from intersection #17 (MD 159 @ Fords
Lane) to intersection #14 (MD 159@ Chelsea Road) do not add up during
.
the AM peak
These volumes would not add up. The difference in trips is due to the numerous
driveway cuts, commercial businesses along MD 159 and E. Michaelsville Road
that connects MD 159 to Chelsea Road.
• MD 159 @ Spesutia Road: The mitigation identified at this failing
intersection is to monitor the intersection during buildout and install a traffic
signal if warranted and approved by MDOT SHA. If the signal isn't
warranted, other mitigation options must be considered and identified in the
study.
Traffic Concepts performed a complete traffic signal warrant analysis for this
intersection, which is included in the attached revised TIS. As noted in the analysis, a
traffic signal is not warranted at this intersection under the existing or the full build out
traffic conditions.
In order to mitigate the traffic impacts associated with the proposed development, the
Developer proposes to revise the geometry at this intersection. The existing free right
turn lane from Spesutia Road to MD 159 will be widened and channelization markings
added to encourage right turning traffic to flow without stopping. Also, the existing
small median along southbound MD 159 will be removed to provide a wider left turn
lane for trucks turning into the private property across from Spesutia Road. This lane
will also be extended to provide a longer queue area for trucks without blocking
southbound vehicles along MD 159 passing through the intersection. The existing
channelized median on the private leg of the intersection will be cut back to improve the
turning radius for large vehicles entering the property. Field observations show that
these intersection modifications will improve the flow of traffic and shorten delay times
for the left turning vehicles from northbound MD 159 and eastbound Spesutia Road. A
conceptual mitigation plan has been included in the revised TIS.

•Chelsea Road @ Woodley Road:Because this intersection wasn't recounted,
there is a major difference between the volumes counted at intersection #15
(Chelsea Road @ Proposed Canning House Road Extended) and intersection
#16 (Chelsea Road @ Woodley Road). Carry thevolumes from intersection
.
#15 to intersection #16 and distribute
Traffic Concepts recounted both intersections on Wednesday, September 7, 2022.
The results are included in the attached revised TIS.
•MD 7 @ Stepney Road: The analysis includes a signal at this intersection
under background and future conditions. While thereare funds available for
this intersection, MDOT SHA approval is required for theinstallation of a
traffic signal. If the installation of a traffic signal is not approved by MDOT
SHA, other mitigation options must be considered and identified.
The Mitchell Property developer will extend the southbound Stepney Road left turn
lane to provide 25-feet of additional storage plus deceleration and taper. The developer
will place in escrow the cost to design and construct this geometric improvement. This
mitigation measure is the same condition placed on the James Run developer and other
developers.
•US 40@ MD 132: The SimTraffic Queuing Analysis shows insufficient
storage for the northbound US 40 left turn lane. The developer is required to
mitigatethe impact at this intersection due tothis project.
The developer will extend the left turn by 25 feet or the length of onevehicle.
This mitigation measure is discussed in the attached revised TIS.
•Synchro: The westbound MD 7 right turnAM and PMvolumes at MD 543 in
the synchro does not match the volumesin exhibit1lA.
The intersection now reflects a single right turn lane and the volumes in the synchro match
the volumes in Exhibit 11A.

Dear Mr. Keeley:
Thank you for the opportunity to review the Point-by-Point response prepared by Traffic Concepts, Inc.
for Mitchell Property Warehouse Development in Harford County. Additional information has also been
provided by Whit MacCuaig, Vice President, Chesapeake Real Estate Group regarding the nature or the
proposed facility. The Maryland Department of Transportation State Highway Administration (MDOT
SHA) has completed our review for this project as currently proposed in the submission listed below.
Mitchell Property Warehouse Development MD 159
MDOT SHA Tracking No. 21APHA021XX
Point-by-Point Response Letter Dated July 29, 2022
Whit MacCuaig Email Dated August 15, 2022
Harford County
As previously noted, the most recently submitted site plan clearly states the development is expected to
have 2389 employees in the largest shift. This raises some questions as to why you are only expecting
832 peak hour trips. The email from Whit MacCuaig indicates the number of employees listed on the site
plan is an error. The email confirms that the proposed development will be a non-sort fulfillment center
with approximately 975 employees during the largest shift. The email further confirms that the site plan
will be revised to accurately state the expected number of employees during the largest shift and to reduce
the number of parking spaces.
Based on this information, MDOT SHA agrees to using trip generation numbers for Land Use 155 (High
Non-Sort
Cube Fulfillment Center Warehouse ). The remaining comments numbers 2 12 from our July
18, 2022 letter still need to be addressed in a point-by-point response. Please submit a revised TIS and
updated synchro analysis along with a point-by-point response to the comments in the July 18, 2022
letter. Submissions must be made through the MDOT SHA Salesforce electronic submission portal
located at the following link,
https://mdotsha.force.com/accesspermit/login?ec=302&inst=1B&startURL=%2Faccesspermit. Please
reference the MDOT SHA tracking number on any future submissions.
