WSB analyzed projected traffic volumes if Hokah Drive became right in/right out and Enid Trail were extended to a 3/4 access at Birch Street as part of a larger Anoka County road improvement project. Projected ADT Projected ADT ` Road (RI/R€I-Hokah (RI/RG-Hokah Drive ? x I?rive Only) & 3/.,at Lod Trail Hokah Drive 175 110 Sioux Lane 950 830 Enid Trail 0 185 The extension of Enid Trail to Birch Street will not significantly change the traffic levels on any of the area streets.Anoka County would need to evaluate whether the benefit to Birch Street would warrant the changes. 7. Section 1001.013 of the Subdivision Ordinance details 5 specific criteria needed to deem a subdivision premature. The attached Resolution No. 16-78 details the finding of fact. Based on ordinance criteria, St. Clair Estates is not a premature subdivision. Cul de Sac Length • Section 302.03(1)(h) states the minimum length of a cul-de-sac shall be 500 feet. The proposed cul-de-sac in St. Clair Estates is approximately 1,200 feet if measured from the intersection of Sioux Lane and Enid Trail or 1,600 feet if measured from the intersection of Sioux Lane and Hokah Drive. A variance shall be required. 1. Cul-de-sacs lengths are limited in length for emergency access concerns for those residents living on that street. This issue is being mitigated by requiring the construction of a 10 foot wide, 7 ton emergency access from the cul-de-sac south to CSAH 34 (Birch Street). Emergency access can be obtained from the south via Birch Street in the event the north intersection at Sioux Lane is blocked. Hydrants will also be located every 300 feet for fire protection. The length of the cul de sac in St. Clair Estates has no impact on the neighboring residents in regards to providing them emergency services. 2. St. Clair Estates is a 35 lot low density residential development. Sioux Lane functioned as a 1,500 foot cul de sac from 2001 to 2012 (11 years) and Hokah Drive functioned as a as 2,000 foot cul de sac from 1979 to 2012 (33 years)without an emergency access trail and without issue. Sioux Lookout is an existing 740 foot cul de sac. West Shadow Lake Road is an existing 7,800+foot cul de sac with trail access on the north through Chomonix Golf Course. Black Duck Drive is an existing 5,500+ foot cul de sac. • 4
