Memorandum City of Springfield
Date: January 4, 2009
To: Mark Metzger, Planner III
From: Jon Driscoll, E.I.T., Transportation Engineer in Training
Subject: DRC2009-00047 Relief Nursery
The Transportation Division has reviewed the materials provided with the subject application.
The required findings and conditions outlined below are provided for your implementation into
the land use decision.
General
Finding: Approval of this proposal would allow construction of a building approximately 14,900
square feet in size, with two playgrounds,and a parking lot that has a capacity for 58 cars. The
organization estimates 44 employees,though all employees will be on site simultaneously. The
site is presently a vacant lot with an existing 10 foot wide bike path along the southern border.
Transportation System Impacts
Finding: Abutting the subject site to the east, 42nd Street is a 46-foot wide paved roadway within
a 70-foot wide right of way. It is a minor arterial with three lanes, improved with curb, gutter,
sidewalk,and HPS street lighting. It provides three motor vehicle lanes (one lane in each
direction, and one turning lane), and one bicycle lane in each direction. Average daily traffic
along South 42nd Street is estimated to be approximately 6,300vehicle trips per day.
Finding: Based on the applicant's Trip Generation Study, the expected daily trip generation of
the site will be approximately 224 vehicle trips per day.
In addition,assumed development may generate pedestrian and bicycle trips. According to the
"Household" survey done by LCOG in 1994, 12.6 percent of household trips are made by
bicycle or walking and 1.8 percent are by transit bus. These trips may have their origins or
destinations at a variety of land uses, including this site. Pedestrian and bicycle trips create the
need for sidewalks,pedestrian crossing signals, crosswalks, bicycle parking and bicycle lanes.
Finding. Sheet L1.1 shows a"Continuous evergreen hedge-6 feet in height..."along the entire
north side of the property.

MOMITIONOMMISDC
Finding: Sheet A1.1 shows a curb between the entering and exiting driveway lanes. The curb
begins 33.5 feet west of the western gutter line of South 42nd Street and run westerly from there.
In the large vehicle simulation (i.e. truck turning template), the applicant shows that the bus's
wheel path strikes a curve that cuts at least 36 feet west of said gutter line, and thus the curb
would be run over by entering and exiting buses. The buses entering from South 42nd Street
would be forced to slow down beyond normal deceleration rates,thus causing surprises for other
drivers and lowering the efficiency and safety of the arterial roadway.
Finding: The truck turning template shows entering and exiting bus paths overlapping. It also
shows the exiting bus mounting a cur within the site.
The final site plan shall show modifications to the site plan so that
the design vehicle(S-Bus-40)with a one foot buffer may maneuver through the site
without striking curbs and may enter the site without crossing the position of a vehicle
queued to exit the site. Work with the Transportation Planner if necessary to obtain a
larger driveway width than the code normally allows, providing modified truck turning
templates.
COMPLIANCE WITH OTHER REGULATIONS AND PERMITING
Finding: SDC 2.1-115(B) states, in part, that"all uses and development shall comply with all
other applicable City,regional, State, and Federal Regulations." This requirement applies to the
Americans with Disabilities Act of 1990(ADA)and requires that all development meet
minimum ADA Standards.
Finding: Section 4.3.2 of the"ADA Accessibility Guidelines for Buildings and Facilities
(ADAAG)" states that, "At least one accessible route within the boundary of the site shall be
provided from public transportation stops, accessible parking, and accessible passenger loading
zones,and public streets or sidewalks to the accessible building entrance they serve."
Finding: Section 4.3.7 of the"ADA Accessibility Guidelines for Buildings and Facilities
(ADAAG)" states that, "4.3.7 Slope. An accessible route with a running slope greater than 1:20
is a ramp and shall comply with [Section] 4.8. Nowhere shall the cross slope of an accessible
route exceed 1:50."
Finding: Section 4.8.2 of the"ADA Accessibility Guidelines for Buildings and Facilities
(ADAAG)" states that, "The maximum slope of a ramp in new construction shall be 1:12."
Finding: The applicant has shown on Sheet A1.1 "ADA Curb Ramps," but on Sheet C3 not all
ramps are shown to be ADA compliant. (E.g. The ramp nearest the northwest corner of the new

building does not have contours that match an ADA ramp. This is shown to be apparent because
the 487 foot contour drawn forms a near vertical curb instead of a sloping ramp.)

Finding: As conditioned above ingress-egress points will be planned to facilitate traffic and
pedestrian safety,avoid congestion and to minimize curb cuts on public streets as specified in
SDC Sections 4.2,4.6, 5.15,& 5.17,applicable zoning and or overlay district Sections,and
applicable refinement plans.
