Scotts Hill Apartments
Trip Generation Memorandum
DAVENPORT Project Number 210239
Prepared for Comet Development
May 19, 2021
This memorandum provides trip generation information for the proposed Scotts Hill
Apartments site, to be located on east side of US 17 in New Hanover County, just south
of the Pender County line. The subject site is part of the Scotts Hill Medical Park site, for
which a TIA was previously completed by DAVENPORT on June 4, 2019. The purpose
of this memorandum is to show that the trip generation of the updated land uses do not
increase the trip generation of the site, and therefore the previously identified roadway
improvements associated with this site should remain adequate.
Figure 1 shows a sketch plan of the subject parcel, as well as the other three (3) parcels
of Scotts Hill Medical Park. The site is accessible by two (2) locations on US 17: a future
access located approximately 550 feet north of Creekwood Road, and by Scotts Hill
Medical Drive which connects to the site via Senca Drive. There is currently a bollarded
southbound left turn lane on US 17 to the future access, which will need removal of the
bollards once the driveway is constructed.
The subject parcel is proposed to consist of 256 apartment units, and two (2)
outparcels. The land use of these outparcels is not yet known. For trip generation
purposes, these were analyzed as 15,000 square feet of retail space.
Table 1 below provides a comparison of the previously analyzed land uses and the
updated land uses, based on information from the developer. Note that one parcel has
been built to date, which is the Wilmington Eye medical office building (“Lot 2” in Figure
1), with a floor area of approximately 23,400 square feet.

Table 2 shows the previous trip generation from the June 2018 TIA. This establishes a
trip generation “budget” against which the new land uses could be compared. Table 3
shows the trip generation results for the updated land uses, as well as the net difference
between the new and old trip generations. Trip generation was computed based on
rates and equations from the ITE Trip Generation Manual 10th Edition, in accordance
with NCDOT Congestion Management standards.

The results in Table 3 show a slight increase in 24-hour trips (+70), a slight increase in
net AM peak hour trips (+5), and a significant reduction in net PM peak hour trips (-75).
The June 2019 TIA identified roadway improvements that would be required for the
Scotts Hill Medical Park development. The current trip generation shows that the
proposed uses have a comparable or lower trip generation than the previous TIA. As a
result, the previously determined roadway improvements are expected to remain
adequate.
Please let us know if you need additional information.
Sincerely,
