acres located in the northwest quadrant of the signalized
intersection of Guilford Avenue and 23rd Street. The parcel has 800
feet of frontage on Guilford Avenue. Guilford Avenue has four
through travel lanes with an eastbound left turn lane with a median
barrier extending from 23rd Street westward to the private
driveway. 23rd Street is a simple two lane street. The PM peak hour
turning movements are shown on an attachment to this project
description.
The developer is proposing to build a neighborhood shopping
center consisting of a 60,000 sq. ft. grocery store, 28,000 sq. ft.
office supply superstore, 10,000 sq. ft. pet supply, a 3,500 sq.
ft. hardware/paint supply store with 5 employees, 36,000 sq. ft.
specialty retail store, 7,500 sq. ft. dress shop, a 9,000 sq. ft.
U.S. Postal Office with 11 employees, plus three outparcels
consisting of a fueling service station with 10 fueling positions
and 6 employees, a 6,000 sq. ft. drive-in bank with 3 drive through
lanes and 10 employees, and a 3,000 sq. ft. fast food restaurant
with drive-through window and ten employees.
Trip generation rates and parking rates are provided as an
attachment to this project description.
There will be a private drive at the western end of the property
with a driveway connection to the shopping center and serves a
single home subdivision located behind and north of the center. The
development may have one driveway on Guilford Avenue and 23rd
Streets. The residential subdivision may also have one driveway on
23rd Street.
Assignment:
1. Begin by determining the total trips on each frontage roadway
and the directional flows (%).
2. Determine the total number of primary and “pass-by” trips
generated by each land use and then assign the turning movements to
each driveway to the shopping center and the private drive. (Using
engineering judgement, assume a reasonable percentage of “pass-by”
trips for the fast food and fueling station businesses.)
3. Show the new turning movements at the signalized
intersection.
4. Design the proposed roadway and intersection
improvements.
5. Show the traffic circulation to the shopping center and the
outparcels.
6. Design the parking lots, pavement markings, signage,
landscaping,
and the nighttime lighting.
7. Design one 400-foot horizontal curve and one 250-foot
vertical curve on the private street. The speed limit is 35 mph and
no hill or horizontal curve shall be greater than 5°.
8. Show one neighborhood park in the residential subdivision and
all single-family lots. The average size of the lots is ½ acre.
9. The project drawing shall be a minimum of 24” x 36”.
