I wIll not be at the DRC meetmg scheduled for next week. I've cc'd Greg and Steve my comments because we have some overlappmg Issues on how to treat the turn-around area at the end of' A' Street.

Thanks, Gary 12/27/2005 IJ Memorandum City of Springfield Subject: December 22, 200S Kitti Gale, Planner II Gary McKenney, P.E., Transportation Planning Engineer SUB200S-0006S Jokinen: Meyer Park Date: To: From: 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 The subject site is located at 4866 Main Street (Map 17-02-32-41, Tax Lots 300,302, and 303). It is approximately 173 feet wide and extends northward approximately 461 feet. North 'A' Street dead-ends into the east property line of the site approximately 320 feet north of Main Street. The applicant proposes to subdivide the existing parcel into 12 lots. Proposed Lots ,I - 10 would be developed as a residential cluster subdivision in the Medium Density Residential (MDR) zone, Lots 11 and 12 would be in the Community Commercial (CC) zone; a residence on proposed Lot 11 would remain. Transportation Facilities Impacts Finding: Main Street (McKenzie Highway) abutting the development site is a 66-foot wide, five-lane arterial state highway that is under ODOT jurisdiction. The street is fully improved with asphalt paving, curb/gutter, sidewalks and street lighting that support multi-modal travel. Average Daily Traffic past the site is approximately 20,000 vehicles. 'A' Street forms a Tee intersection with 49th Street and extends westward 170 feet to the site boundary, abutting that portion ofthe property proposed for the cluster subdivision (Lots 1 - 10). 'A' Street is 28-feet wide and abutting properties are fully developed with four homes. Existmg traffic volume is approximately SO vehicle trips per day. The adopted Conceptual Local Street Plan does not call for 'A' Street to be extended west of Its present terminus as a public street; there are several sound reasons for avoiding this extension. · The 28- foot street width supports planning to limit traffic volume on 'A' Street, · Once the planned traffic signal at Main/48th Streefis constructed, extending 'A' Street to 48th Street would invite cut-through traffic seeking signalized access to/from Main Street, · A straight-line extension of' A' Street to 48th would pass through land zoned Community Commercial. Such a direct link between commercial uses and existing residential uses would not be compatIble with the narrow street width. · To avoid such an alignment and allow for efficient residential development on abutting land, the' A' Street extension would need to be routed further toward the SUB2005-00065 Jokmen Meyer Park December 22, 2005 Page 2 of 3 north. But, a more northerly alignment would create an undesirably short block length between 'A' and 'B' Street to the north. Finding: For Lots 11 and 12, which are zoned CC; approval of this proposal would not result in any potential increases in vehicular traffic that would not be addressed later during a Site Plan Review process. For that portion of the property zoned MDR, approval of this application would allow construction of residential units without further land-use review. Based on ITE Land Use Code 230 (Residential Condominium/Townhouse) vehicular trip generation from this use is estimated to be as follows: · Average Weekday = 10 dwelling units x 9.57 trips per dwelling units = 96 trips · PM Peak Hour = 10 dwelling units x 1.01 trips per dwelling units = 101 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 of land uses, including this use. Pedestrian and bicycle trips create the need for sidewalks, pedestrian crossing signals, crosswalks, bicycle parking and bicycle lanes. Finding: As conditioned below, existing transportation facilities would be adequate to accommodate additional vehicular and pedestrian traffic that would be generated by the proposed development. Site Access and Circulation Finding: Installation of dnveways on a street increases the number of traffic conflict pomts. 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 techniques permits 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 a public street." Finding: Existing access to the proposed subdivision site is via two driveways onto Main Street near the east and west property lines. The applicant proposes to close the eastern driveway and maintain access to the residence via an existing 25-foot wide private access easement along the west side of Lot 12 connecting to the western driveway at Main Street. Under this proposal Lot 11 would remain with a residential use in the commerCial zone, with no street frontage. If/when the lot is redeveloped with a commercial use it would be ~ 'I' . SUB2005-00065 Jokmen Meyer Park December 22, 2005 Page 3 of 3 inappropriate for that development to take its access through the adjoining residential neighborhood via 'A' Street. Access to the house on Lot 11 should continue to be via Main Street as proposed, which will minimized the need to alter access arrangements in the future. Finding: The applicant proposes to provide access to Lots 1 - 10 by constructmg a 20- foot wide private driveway extending from the end 'A' Street into the cluster subdivision. A wider paved area would be constructed adjacent to the end of 'A' Street to provide for vehicular turnaround. 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: Prior to final plat approval, close the eastern site driveway onto Main Street as proposed. Recommended Condition: Prior to final plat approval, place a deed restriction on Lot 11 prohibiting access to 'A' Street. Recommended Condition: Prior to final plat approval, execute and record a public access easement over the paved turnaround area at the end of 'A' Street. Prior to recording, the dimensions of this easement shall be approved by the Transportation Planning Engineer. Please provide a copy of the draft Decision for my review prior to issuing the final decision.
