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 ofthese technique,s 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 g public street" i Findin!!: Existing access to the property is via a 14-foot wide driveway onto Hayden Bridge Road, which would be closed, The applicant proposes a multi-panhandle lot configuration'and 26-foot widejoint"use access easement to serve Parcels 1,2 and3 a driveway onto Hayden Bridge Road South located at the north property boundary, Access to Lots 4- 10 would from 19th Street via a new cul-de-sac street, King Henry's Court, located approximately ISO feet north of the centerline of Hayden Bridge Road, No lots would take dir~ct to Hayden Bridge Road or 19th Street Findinl!: As conditioned below ingress-egress points will be planned to facilitate traffic and pedestrian safety, avoid congestion and to minimiz~ curb cuts on public'streets as specified in SDC Articles 31 and 32, applicable zoning and or overlay district ArticJ'es, and applicable refinement plans, Transoortation System Imoacts and Imorovements . , " SUB2005"00030 King Henry's Court Subdivision June 28, 2005 Page 2 of 2 Finding: Abutting the subject site, both Hayden Bridge Road and 19th Str!"et are two-lane major collector streets, and are under Lane County jurisdiction, The streets are improved with paving, curb/gutter, bicycle lanes, street lights and sidewalks,which support multi-modal traveL Traffic volumes on Hayden Bridge Road and 19th Street are approximately 8,400 vehicles per day and . 3700 vehicles per day respectively. L TD Route # 12 provides regular transit bus service to the site along Hayden Bridge Road and connecting to the greater transit system via Springfield Station. At the intersection of Hayden Bridge Road/I,9th Street dedicated'left-tum lanes ar~ provided and traffic is controlled by a multi-phase traffic signaL Finding: Based on ITE Land.Use Code 2.10 (Single-Family Detached Housing) trip generation from the four additional dwelling units allowed by this subdivision would be as follows: o AverageWeekday ~ 10 dwelling units x 9,57 trips per dwelling unit = 100 trips o PM Peak Hour = 10 dwelling units X 1,0 I trips per dwelling unit = 10 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 made 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, Finding: The applicant proposes to install a new street light at the northwest comer of 19th Street and King Henry's Court, This location would not be well suited to cast fight to the west end of the proposed ISO-foot deep cul-de-sac, And, there already is a street light mounted to the power pole directly opposite on the east side of 19th Street A 100-watt High Pressure Sodium street light installed at the entrance to the cul-de"sac bulb is needed to adequately light the street in compliance with current City current design standards, finding: As conditioned below, existing and planned transportation facilities would be adequate to accommodate additional trips that would be generated by the proposed development in a safe and efficient manner. Recommended Condition: Execute and record ajoint-use access easement to benefit Parce.ls 1, 2 and 3 as proposed. Recommended Condition: Provide and maintain, adequate vision clearance triangles at the corners of all site driveways per SDC 32.070: . . Recommended Condition: Install a 100-watt High Pressure Sodium street light at the entrance to the cul-de-sac bulb on King Henry's,Court. Comment: Construction activities 'within the abutting Hayden Bridge Road and 19th Street rights'of-way will require permits from Lane County.
