Page 4 separately at a future date. The watermain improvements are shown on Figures 6B and 6C. VI I. ROADWAY IMPROVEMENTS The majority of the internal site roadways will be constructed as the developments are constructed. The primary access point will be 173rd Avenue at Nowthen Boulevard. Supplemental access points will be along 175th Avenue for the Hunt Addition and along Variolite Street for the Makowsky Addition. These supplemental accesses are anticipated to have low traffic volumes and will access onto roadways with less than 1,000 ADT per 2019 traffic count data. Additionally, sight distances are adequate for turning movements into and out of the developments. The supplemental access points appear adequate from both roadway capacity and safety perspectives. Hunt Addition A traffic analysis was completed which includes requirements for the ultimate improvements needed assuming both properties develop. Considering recommendations from the analysis, if the Hunt property develops independently, the following improvements will be required: • Construction of a left turn lane along Nowthen Boulevard, • Construction of 173' Avenue to the internal access road for the development, • Construction of a right turn lane and left turn lane for eastbound traffic at Nowthen Boulevard, and • Construction of a temporary cul-de-sac at the west end of 173rd Avenue. Hunt Addition and Makowsky Addition If the developments occur simultaneously, the improvements are anticipated to include: • Construction of a left turn lane along Nowthen Boulevard, and • Construction of a right turn lane and left turn lane for eastbound traffic at Nowthen Boulevard. EAW Process The developer for the Makowsky property is completing a traffic study as a portion of the EAW process. The traffic study they are completing may identify and recommend additional roadway improvements within the general project area. The roadway improvements are depicted on Figure 7. The traffic analysis is also attached for reference. VIII. ASSUMPTIONS a. Right -of -Way Requirements We have assumed that most of the required improvements will be development driven and right of way will be secured through the platting process. During the development review process, the City should review the right of way required and secure needed easements. Various other utility easements may also be required, depending upon how the combined sites develop. Prepared by: Bolton & Menk, Inc. Trott Brook North Infrastructure Study — City of Ramsey
