Each of the these has the potential to impact the developments within The COR area. Regional Stormwater Retention Pond Analysis The regional stormwater retention pond located within The COR is often referred to as The Waterfront, and is proposed to be constructed north of Ramsey Parkway, South of Bunker Lake Boulevard, west of Center Street and east of Zeolite Street. The City is currently analyzing potential construction methodologies, sequencing strategies, and timing of pond construction. The general pond configuration is depicted on the exhibits for this report, and the land use is considered in the analysis. The Waterfront There are several park related improvements in the development stage at this time. Park features around The Waterfront and along Center Street are currently in the schematic design phase. As the current sketch plans are further refined, adjacent public infrastructure improvements may be influenced by those designs. Currently, phase 1 of the improvements, have been progressing. The phase 1 area is depicted on Figures 1 and 13. Municipal Plaza The proposed Municipal Plaza, located north of Sunwood Drive, south of Ramsey Parkway and west of Center Street, is also in the planning stages. A key component, previously analyzed, was focused on stormwater reuse within the park. Regional Infiltration Basin (southeast area of The COR) Much of The COR is restricted relative to storm water infiltration. The City constructed a regional infiltration basin in the southeast portion of The COR in 2019. The roadway alignments in this area of The COR were based upon the infiltration basin layout. US HWY 10/169 Improvements Interchange and frontage road improvements at Ramsey Boulevard and Sunfish Lake Boulevard are anticipated to begin in Fall of 2023 and continue through 2025. A southbound right turn lane is proposed at the intersection of Ramsey Boulevard and 143' Avenue. The configuration is anticipated to impact final roadway and utility alignments in that portion of The COR. Bunker Lake Boulevard Bunker Lake Boulevard, from Ramsey Boulevard to Armstrong Boulevard, is under the jurisdiction of Anoka County. Exhibits depicting the future configuration are included in this report and are based off of information from the Anoka County 2030 Transportation Plan. Lane geometry and vertical grades were considered as a part of this analysis, as they have the potential to impact other roadways within The COR. See Figures 2 and 3 in Appendix B.
