Memorandum City of Springfield Date: To: From: Subject: November 14,2005 Sarah Summers, Planner II Gary McKenney, PE, Transportation Planning Engineer DRC2005-000n - Dukes & Dukes Site Plan The Transportation Division has reviewed the materials provided with the subject application. The recommended findings and conditions outlined below are provided for your use in preparing the land-use decision, General Finding: The development site is a 0,54-acre parcel located on the west side of 28th Street, south of 'G' Street (Map 17033611, Tax Lot 11300), Approval of this proposal would allow construction of four duplex residential units and associated parking; an existing home on the site would be removed, Transportation System Impacts Finding: 28th Street is designated a minor arterial street in the RTP, The roadway is 36 feet wide and is improved with paving, curb, gutter, sidewalk and low pressure sodium street lighting, The roadway provides single northbound and southbound travel lanes and a two-way center turn lane, Finding: Based on ITE Land Use Code 220 (Apartment), development of the site as proposed (eight dwelling units) would generate 54 additional vehicle trips per day and 5 PM peak-hour vehicle trips onto 28th Street. 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: To provide for safe pedestrian and vehicular access, 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 Illuminating Engineering Society (IES) American National Standard Practice for Roadway Lighting RP-8, specify the lighting type and required lighting levels for street and pedestrian areas, In low and medium density residential districts these standards specify high pressure sodium type street light fixtures. For a 36-foot wide asphalt street, such as 28th Street, the table below shows the required horizontal illuminance, street light type and spacing needed to achieve this lighting level. Street, Width, Classification 28 Street, 36', arterial Re uired Illuminance 9.4 foot-candles Date'i":6ceived:--i/-;/d.>/n Planner: AL / . " . DRC2005-00073 - Nadel sillan November 14, 2005 Page 2 of 2 . Finding: The development site has 70 feet of frontage on 28th Street. Existing lighting which contributes to illumination of this frontage consists of a 90-watt low~pressure sodium street light on the west side of 28th Street at the southern site boundary. This street light does not provide the quality or quantity of illumination necessary to meet adopted city standards for safe and efficient traffic movements. Based on 70 feet of street frontage, the proposed development significantly contributes to the need for street and sidewalk illumination required to meet adopted city standards. Construction by the applicant of street lighting improvements, in proportion to the need created by the proposed development, and aimed at meeting the adopted standards would be appropriate. However, construction of such limited improvements is not economically or technically practicable at this time. Execution of an Improvement Agreement is an appropriate method of assigning this cost responsibility. Recommended Condition: Execute and record an Improvement Agreement for street lighting on 28111 Street. Finding: As conditioned, existing and planned transportation facilities would be adequate to safely accommodate additional vehicular and pedestrian traffic generated by the proposed development. 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 32.080(1) (a) stipulates that each parcel is entitled to "an approved access to !! public street." Finding: Current access to the site is via a 16-foot wide driveway onto 28th Street located near the southern site boundary. The applicant proposes to close this access and construct a new 20- foot wide driveway at the northern site boundary. Finding: SDC Table 32-2 specifies that the throat depth for driveways serving multi-family residential developments shall be a minimum of 18 feet as measured from the curb face to the first parking stall. Parking stall # 1 depicted on Plan Sheet 4 of 7 is located 12 feet from the face of curb on 28th Street.. . Recommended Condition: The on-site parking layout shall be re-designed to comply with the standards in SDC Table 32-2. Recommended Condition: Provide and maintain adequate vision clearance triangles at the corner of the site driveway per SDC 32.070. Please provide a copy of the draft Decision for my review prior to issuing' the final decision. Date Received: j'~/~'b I Planner: AL
