Recommendation Staff recommends the basic lighting package, which should include additional lights at the City Hall and the church entrances for special safety reasons. The additional lighting provided for special safety reasons should be paid for by the County. 5. Signalization The Arden Hills major intersections identified in the draft report where traffic signals may be warranted are: the 35W ramps, U.S. Highway 10, Snelling Avenue (if it is an access to TCAPP property, Hamline Avenue, and Lexington Avenue). The total costs for the identified signals is estimated to be $480,000, of which all but $40,000 would be eligible for Federal or County State Aid Highway (CSAH) turnback funds. a. Recommendation Staff recommends all of the identified intersections be signalized plus the proposed Arden Manor/Round Lake Road intersection. Staff would recommend that the County coordinate all the signals to keep traffic moving and to incorporate an EVP (Emergency Vehicle Preemption) system into the basic package at no cost to the City. 6. Utilities Any new City utilities installed as part of the project shall be paid for by the City, which would include sewer, water, and storm sewers. The engineers have made a preliminary estimate which Ramsey County believes to be conservative. This estimate projects the cost of storm sewer for the first segments (Old Hwy.IO to Hwy.8) to be $310,000, of this, $77,500 would be paid by the City while the rest would be covered by Federal and CSAH turnback funds. The storm sewer on the second segment (Old Hwy. 10 to Lexington) is estimated to cost $780,000, of which $585,000 would be eligible for CSAH turnback funds, leaving $195,000 to be paid for by the City. These costs do not include ponds, easements or water quality treatment fixtures, which will be needed. If a rural road construction design were used rather than an urban construction design, then the storm sewer costs could be significantly reduced, if not eliminated. a. Recommendation Staff recommends installation of the necessary storm sewer plus one 16" casing for a future watermain crossing at Snelling Avenue. The County would pay for any storm sewer costs above the $272,500 estimated tor the Arden Hills segments.
