An existing house on the property would remain on Lot 4. Transoortation Svstem Imoacts Findinl!: Based on ITE Land Use Code 210 (Single-Family Detached Housing) additional trip ,generation from this subdivision is estimated to be as follows: . A verage Weekday = 11 dwelling units x 9.57 trips per dwelling units = 105 trips . PM Peak Hour = 11 dwelling units x 1.01 trips per dwelling units = 11 trips . In addition, the assumed development would generate pedestrian and bicycle trips. According to the "Household" survey done by LCOG in 1994, 12.6 percent of household trips are lliade by bicycle or walking and 1.8 percent are by transit bus. These trips may have their origins or destinations at a variety ofland uses, including this use. Pedestrian and bicycle trips create the need for sidewalks, pedestrian crossing signals, crosswalks, bicycle parking and bicycle lanes. Findinl!: The development site is situated at the south end. of an existing dead-end section of South 56th Street and has 9 I feet of frontage on the west side of south 57th Street. Both streets abutting the site are fully improved. The applicant proposes to extend South 56th Street southward approximately 340 feet as a 36-foot wide local street in a 60-foot wide right of way. Findinl!: Note 2 on Plan Sheet 2 states that no new street lights are proposed, however, one new low pressure sodium street light is depicted on the plan.

Recommended Condition: Street light shall be installed as part of public street improvements in accordance with city design standards. Subdivision 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. Effective ways to reduce the probability of traffic crashes include: reducing the number of driveways, increasing distances between intersections and driveways, and establishing adequate vision clearance where driveways intersect streets. Each of these techniques pennits a longer, less cluttered sight distance for the motorist, reduces the number and difficulty of decisions drivers must make, and contributes to increased traffic safety. SDC 32.080(1) (a) stipulates that each parcel is entitled to , "an approved access to i! public street." Finding: The applicant proposes to continue access to the house on Lot 4 via the existing driveway onto South 57th Street. Proposed layouts for the remaining lots would provide. adequate street frontages to allow future driveways to be constructed in compliance with the standards of SDC Article 32. 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 <)sspecified in SDC Articles 31 and 32, applicable zoning and or overlay district ArtiCles, and applicable refinement plans.
