Page 1 I. INTRODUCTION The City of Ramsey has identified the need to prepare for the development of an area generally located north of Trott Brook, south of 175th Avenue, between Nowthen Boulevard and Variolite Street (see Figure 1). The proposed development area is not serviced with municipal utilities, therefore a general review of the entire service area north of Trott Brook was performed. In addition, transportation improvements were reviewed for the intersection of 173' Avenue and County Road 5/Nowthen Boulevard, which will serve as the primary access point for the proposed development area. Based on the current zoning map (January 2020), the area is zoned R-1 MUSA. II. PRELIMINARY CONSIDERATIONS Required public utility improvements are based on information contained in the City's Sanitary Sewer (Figure 2) and Water System (Figure 3) Comprehensive Plans. The trunk sanitary sewer and water system improvements are considered as base requirements for development of this area. The roadway improvements reviewed are consistent with concept plans received for the developments. The anticipated roadway improvements along Nowthen Boulevard are also consistent with Anoka County standards. The roadway geometrics may require additional analysis if the proposed land uses change. III. DESIGN CONSIDERATIONS The design of the trunk sanitary sewer system is based on flow projections and rates detailed in the Comprehensive Sanitary Sewer Plan and the current City Zoning Map (dated January 2020). See Figure 4 for the City Zoning Map used for this analysis. Capacity limitations were analyzed at key points in the system. IV. DEVELOPMENT CONCEPTS Two potential developments are being considered for the area north of Trott Brook, west of Nowthen Boulevard. The specific properties being evaluated for this study include: Hunt Addition: A 35.5-acre parcel between 173rd Avenue and 175th Avenue, west of Nowthen Boulevard. The Hunt Addition currently proposes to include 77 single family lots with the development traffic using both 173rd Avenue and 175th Ave NW to access Nowthen Boulevard. Makowsky Addition: An approximate 200-acre parcel directly north of Trott Brook between Nowthen Boulevard and Variolite Street. The Makowsky Addition currently proposes to include 270 single family lots with development traffic accessing Nowthen Boulevard at 173rd Avenue, with an additional site access along Variolite Street approximately 1800 feet north of Trott Brook. Three development scenarios were reviewed: • The Hunt Addition develops as a stand-alone project (Figure 5A), • The Hunt Addition and a portion of the Makowsky Addition develop simultaneously (Figure Prepared by: Bolton & Menk, Inc.
