4.0 Traffic Analyses The questions presented earlier are addressed next. Q: Is the proposed development access plan feasible and will it provide adequate traffic operations? As previously stated, access to the development would be provided by a local street with one connection at the south end of the property to CSAH 14 and one connection at the north end of the property to Pine Street. The first step in assessing the feasibility of the proposed access plan is to identify the applicable access spacing guidelines in the vicinity of the project. The following sections address each access individually. CSAH 14 Access The County's access spacing guidelines are based on roadway functional classification and area type. CSAH 14, within the study limits, is functionally classified as a "Principal Arterial ". Considering the surrounding area and the 40 mile per hour speed limit on CSAH 14 at the proposed development access, the most applicable area type for this roadway section is "urbanizing ". The Anoka County access spacing guidelines published in the Anoka County Highway Department Development Review Process (Dec. 2003) are; 1/2 -mile (2640 feet) for primary full movement intersections, 1/4 -mile (1320 feet) for conditional secondary intersections, and 1/2 -mile (2640 feet) signal spacing for a principal arterial in an urbanizing area. A secondary source of access guidance for CSAH 14 is the TH 212 /CSAH 14 Access Management Study (1999). This study provides an access management plan for the TH 242 /CSAH 14 corridor that promotes management consistent with the routes function (principal arterial) and the mobility needs of the region. Guidance provided in this secondary source differs only in the spacing of the secondary intersections, indicating 1/6 -mile (880 feet) as recommended spacing for secondary intersections. The access management study identifies these secondary intersections as right - in/right -out only. The access management study identified the following existing locations along CSAH 14 as full - movement intersections: • CSAH 14/4`h Avenue North • CSAH 14/Wood Duck Trail • CSAH 14 /CSAH 23 (Lake Drive)
