The design and construction of streets and public improvements shall be in accordance with section 18.4.6.040 Street Design Standards, except as otherwise required for the following facilities within the Croman Mill District. A change in the design of a street in a manner inconsistent with the Croman Mill District Street Design Standards requires a minor amendment in accordance with subsection 18.3.2.030.B. 1. Central Boulevard. The tree-lined boulevards along Siskiyou Boulevard and Ashland Street are an easily identifiable feature of Ashland’s boulevard network. Application of this street design to the central boulevard will create a seamless boulevard loop, linking the Croman Mill District with downtown Ashland. The central boulevard also serves as the front door to the Croman Mill District, creating a positive first impression when entering the district. Options addressing the street configuration and intersection geometry will be evaluated with the final design of the central boulevard. See central boulevard location in Figure 18.3.2.060.A.1.a and street cross section in Figure 18.3.2.060.1.b. Figure 18.3.2.060.A.1.a. Street Framework Figure 18.3.2.060.A.1.b. Central Boulevard 2. Phased Street Plan. Build-out of the central boulevard can be accommodated through a phased development plan. a. Phase I implementation will require the following. i. Maintain the existing Mistletoe Road alignment from Tolman Creek Road to the northwest corner of the Croman Mill site as illustrated in Figure 18.3.2.060.2.a.i. Figure 18.3.2.060.2.a.i. Phase I Central Boulevard iiInclude developer-constructed minor improvements to the existing portion of Mistletoe Road such as a minimum six-foot wide sidewalk on the north side of the street, two 11-foot travel lanes and the addition of a left-turn pocket at the intersection with Tolman Creek Road. iiiA developer-constructed three-lane central boulevard from the northwest corner of the district to Siskiyou Boulevard. b. Phase II implementation will require the following. See Figure 18.3.2.060.2.b. Figure 18.3.2.060.2.b. Phase II Central Boulevard Alternatives i. Options addressing the street configuration and intersection geometry will be evaluated with the final design of the central boulevard. Final street configuration may involve a modification in the central boulevard cross section (e.g., delete on-street parking lanes) to address limitations to right-of-way width (e.g., existing buildings). ii. The alternative central boulevard location and realignment of Tolman Creek Road is contingent upon property owner’s consent, and future sale and relocation of the existing ODOT maintenance yard. 3. Tolman Creek Road Realignment. Additional traffic will be generated by the redevelopment of the Croman Mill District. The alternative central boulevard location includes the realignment of Tolman Creek Road with the central boulevard to discourage non-local through traffic in the Tolman Creek neighborhood and in the Bellview School area as illustrated in Figure 18.3.2.060.A.3.a and Figure 18.3.2.060.A.3.b. The modifications to the street network will preserve neighborhood character and address impacts to the neighborhood by directing traffic away from the neighborhood and Bellview School, and toward the Croman Mill District while maintaining access to Tolman Creek Road for neighborhood-generated trips as illustrated in Figure 18.3.2.060.A.3.c. Key elements of the realigned Tolman Creek Road include the following. a. Two through traffic lanes and a northbound turn lane. b. New traffic signal. c. Bike lanes. d. Sidewalks separated from auto traffic by landscaping and canopy trees. e. Landscaped neighborhood gateway. f. Evaluation of the intersection alignment of local streets with Tolman Creek Road including Takelma Way, Grizzly Drive and Nova Drive. Figure 18.3.2.060.A.3.a. Central Boulevard Alternative Figure 18.3.2.060.A.3.b. Tolman Creek Road Realignment Figure 18.3.2.060.A.3.c. Neighborhood Center 4. Local Commercial Streets. Local commercial streets provide district circulation to and from employment uses, the Central Park, and the neighborhood center. See Local Commercial Street locations illustrated in Figure 18.3.2.060.A.4.a and the street cross section in Figure 18.3.2.060.A.4.b. Figure 18.3.2.060.A.4.a. Street Framework Figure 18.3.2.060.A.4.b. Local Commercial Street 5. Protected Bike Lane. The protected bike lane runs parallel to the central boulevard and connects with the City’s existing Central Bike Path in two locations – adjacent to the Central Park and at the neighborhood center as illustrated in Figure 18.3.2.060.A.5.a. The design of the protected bike lane should include the following elements, as illustrated in Figure 18.3.2.060.A.5.b. a. A grade-separated two-way colored bicycle lane buffered from on-street parking by landscaping. b. A sidewalk separated from the bicycle lane by striping, bollard, grade separation or other treatments. c. Tabled intersections. d. Elimination of auto right turns on red at intersections. e. Incorporate rumble strips along the bike lane at the approaches to all intersections. f. Signage, lighting or other treatments to alert drivers, pedestrians, and riders approaching intersections. g. Consideration of a bikes-only signal phase at signalized intersections. Figure 18.3.2.060.A.5.a. Pedestrian and Bicycle Framework Figure 18.3.2.060.A.5.b. Protected Bike Lane 6. Multi-Use Paths. The multi-use paths provide pedestrian and bicycle connections between the district and adjacent neighborhood, employment, and commercial areas as illustrated in Figure 18.3.2.060.A.6.a. The plan includes extension of the Central Bike Path and establishment of the Hamilton Creek Greenway trail. The Central Bike Path extends the existing multi-use path along the southern edge of the CORP rail line within a 20-foot wide dedicated easement (see Figure 18.3.2.060.A.6.b and serves as a viable commuter route and link to the downtown. The Hamilton Creek Greenway trail provides access to the neighborhood center and an east/west connection across the creek. See the multi-use path and Central Bike Path cross sections in Figure 18.3.2.060.A.6.c, Figure 18.3.2.060.A.6.d, and Figure 18.3.2.060.A.6.e. Figure 18.3.2.060.A.6.a.
