o The cul-de-sac is proposed to be located on the south end of Ferret Street as <br />a portion of the right-of-way at 146th Avenue will be needed for the shared <br />regional pond. <br />• Option 2 — Roadway Pond <br />o This option proposes a smaller pond sized to accept stormwater runoff from <br />the project roadway improvements. <br />o Pond to be located on the City -owned parcel on the southeast end of 146th <br />Avenue NW. Right-of-way and or easement acquisition is not anticipated <br />for the pond. <br />o The cul-de-sac is proposed to be located on the east end of 146th Avenue <br />NW, approximately matching the existing cul-de-sac footprint. <br />Driveways: <br />Existing driveway aprons may need to be reconstructed to varying degrees. The limits of <br />construction will vary with each driveway apron based on the elevation of the street <br />abutting the driveway and the driveway pavement type. During design, Staff will evaluate <br />the construction limits for each driveway and will incorporate this into the plans, but as <br />with all street reconstruction projects, the exact limits of construction will be determined <br />in the field during construction. None are anticipated, but right -of -entry forms will be <br />obtained from private property owners where work is required outside city rights -of -way <br />and easements. <br />Irrigation Systems: <br />Developed properties along the project corridor may have private irrigation systems. Staff <br />will notify property owners of pending construction as far in advance as practical to allow <br />them time to relocate their irrigation systems before construction begins. <br />Parking Restrictions: <br />Parking is currently provided along both sides of the streets and is not currently restricted <br />except for overnight parking per City code. During project construction, parking will be <br />restricted during allowable working hours. <br />Pavenient Coring: <br />Existing pavement thicknesses have been found to be inconsistent throughout the City. It <br />is now standard practice to have City Staff on -site during pavement installation to ensure <br />the proper quantities are being placed. As further conformation, Staff is proposing to <br />collect GPR data or to have pavement cores taken at the conclusion of all reconstruction <br />projects. This is already a requirement on all State Aid projects and will leave more data <br />on the pavement section for future street maintenance projects. <br />4.2 Stormwater Treatment <br />The extension of Ferret Street from the north termini cul-de-sac to Bunker Lake Boulevard <br />results in an impervious area increase of 0.4 acres. Also, the existing storm sewer on 147t1' <br />Avenue drains to existing ponds east of Armstrong Boulevard and north of Sunwood <br />Drive. They were not designed to receive any runoff west of Armstrong Boulevard. <br />Consequently, stormwater retention and/or treatment improvements will be required with <br />this project to reduce the rate at which runoff leaves the site or infiltrates. <br />Feasibility Report Update <br />HI -10 Ramsey Improvements <br />City of Ramsey Project No. 18-02 <br />Page 8 <br />
