491 issues in that area and flow issues for the nursing home and other problem areas 492 (e.g. Sherren and Dellwood areas) as part of that extended drainage management 493 mitigation. Mr. Culver noted that there were several open spaces that may allow 494 for shared ponding between the City and MnDOT; and assured members that staff 495 would continue working with them on that aspect. 496 497 At the request of Chair Stenlund, Mr. Culver advised that based on the noise 498 analysis performed by MnDOT, as long as no lanes were being added at this time, 499 no noise walls were required. However, when the third lane occurred, Mr. Culver 500 advised a noise wall would need to be installed, an sed on preliminary noise 501 wall studies along this corridor indicating areas t alified under those 502 standards. 503 504 505 506 507 508 509 510 511 512 513 514 At the request of Member Gjerdingen, Mr. Culver advised that a mill and overlay of Lexington in that area would be included as part of the project; and while MnDOT has accommodated the City's request for a 10' clear zone on the east side of Lexington, it was doubtful they would agree to any additional widening to accommodate pedestrian facilities due to lack of additional funding, and the need for Ramsey County to fu additional b e length to accomplish that additional width. At the request o ember Gjerding n, Mr. Culver roughly estimated the cost for six lanes with s4holders at a significant amount per linear foot, $100 - $150 per square foot of additional bridge. Mr. Schwartz concurred, and advised that Ramsey County did not foresee, in the 515 next twenty years nee ing additional capacity in this area which may be a value 516 judgment eir part ut supporting their cost analysis projections and 517 planning. 518 519 ember Gjerdingen opined t at this put City in a tough spot; and questioned 520 how the cross section of road under the bridge compare to the north/south areas of 521 Lexington and Sherren. 522 523 M Iver advised that there would be about the same area as far as width on the 524 left, nd it smaller than the rest of the roadway, it seemed prudent to expand the 525 width unless this is a natural chokepoint. However, Mr. Culver opined that it 526 would be difficult for the City to consider expansion of Lexington Avenue north 527 or south of the bridge to add a full additional travel lane, based on available of 528 rights-of-way. 529 530 Additional discussion ensued regarding Member Gjerdingen's concerns about 531 sufficient space on the shoulder for pedestrian and bicycle traffic; 40 mph speeds 532 posted on Lexington Avenue; with Member Gjerdingen offering to personally 533 measure the roadway to alleviate his curiosity and concerns; seeking assistance 534 from staff to determine the actual right-of-way locations and widths. 535 Page 12 of 18
