The Transportation Division has reviewed the materials submitted with the subject application.
The recommended findings [!nd conditions outlined below are provided for your use in preparing
the land-use decision.
General
Finding: The subject property is a 9,943 square-foot vacant parcel located on the east side of
18'h Street, north of' l' Street (Map 17-03_25-34, Tax Lot #7100). The property is zoned Low
Density Residential (LDR). The applicant proposes to partition the property into two parcels; an
existing residence would remain on Parcel 1.
Transportation System Impacts
Finding: Abutting the subject site, 18th Street is a 36-foot wide local street within a 60-foot wide
right of way. The street is improved with paving, curb/gutter and low pressure sodium 'street
lighting; there are no sidewalks on the property frontage, Average daily traffic on 18th Street is
approximately 3,600 vehicle trips per day.
Finding; Based on ITE Land Use Code 210 (Single-Family Detached Housing) development of
the one new parcel would generate 10 additional vehicle trips per day and I PM peak_hour
vehicle trip onto the surrounding street. system. In addition, assumed development may generate
pedestrian and bicycle hips, According to the "Household" survey done by LCOG in 1994, 12.6
percent of household trips are made by bicycle or walking and' I ,8 percent are by transit bus.
,
These trips may have their origins or destinations at a variety. ofland uses, including this site.
Pedestrian and bicycle trips create the need for sidewalkS, pedestrian crossing signals,
crosswalks, bicycle parking and bicycle lanes. The applicant proposes to construct sidewalk
improvements along the full site frontage.
Finding; A 90-watt low-pressure-sodium street light is mounted to a SUB-owned pole located on
the west side of'S' Street opposite the northern site boundary. To provide for safe pedestrian
and vehicular traffic movements during nighttime hours street lighting is needed that will
adequately illuminate the street and sidewalk areas adjacent to the development site. The city's
street lighting standards, which are based on the Jlluminating Engineering Society (IES),
American National Standard Practice for Roadway Lighting - RP - 8, specifY the use of high-
pressure sodium street lights in residential zones,
Finding; Additional vehicular and pedestrian traffic created by develop!nent of the subject

accommodate all modes of traveL As conditioned below, existing and planned street
improvements would be adequate' to accommodate additional traffic generated by development
on the proposed new parcel in a safe and efficient manner.
Recommended Condition: Execute and record an Improvement Agreement for street
lighting improvements on 18th Street.
Site Access and Circulation
Finding: Installation of driveways on a street increases the number of traffic conflict points. The.
greater number of conflict points increases the probability of traffic crashes. SDC 32.0S0(l) (a)
stipulates that each parcel is entitled to "an approved access to !! public street."
Finding: Existing access to the property is' via a break in the curb of IS'h Street and a gravel
surfaced driveway located near the southern property boundary.

have no street frontage. The applicant proposes construct a 15- foot wide standard driveway
apron at the existing driveway location to serve Parcel I, and to provide access to Parcel 2 via a
.new driveway over an IS-foot wide easement along the north side of Parcel I, As proposed, a
portion of the driveway apron serving Parcel 2 would extend beyond the property frontage and
encroach onto the frontage ofthe.adjacent property to the north, Re-design of this driveway is
required to eliminate the encroachment. .
Finding: As conditioned below 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 Articles 31 and ,32, applicable zoning and or overlay district Articles, and applicable
refinement plans. '
Recommended Condition: The driveway proposed to serve Parce.I.2 shall be constructed
so as to be entirely within the applicant's property frontage.
