. . . URS MEMORANDUM Thresher Square 700 Third Street South Minneapolis, MN 55415 Phone: (612) 370-0700 Fax: ((>12) 370-1378 To: J(ris Giga/ City of Arden Hills Michelle Wolfe/AH Frank Ticknor/URS F'ile: 37951005 Copy: From: Greg Bro\,'n Project Manager Date: May 30, 2006 Snbject: 3153 Shoreline Lane Driveway Background: As a part of the 2004 PMI' Ridgewood l1eighborhood reeonstmctiol1 project, the driveway at 3] 53 Shoreline Lane was reconstructed in October of 2004. The roa(hvay pavement elevation was designed to match the preexisting roadway centerline in the area oflhis property. The new curb and driveway apron elevation did result in a situation which caused the driveway at 3153 to become flatter than its preexisting condition (0.3% vs. approximate original grade of 0.5%). The URS field inspector discussed this situalion with the hODlU)\VnCr a1 the time of initial construction and recommended that a concrete drivev..'3Y be constructed to better accommodate the flatter grade. The homeoyvner preferreclthe look of bituminous and, as a result. the driveway \vas reconstructed with bitnminous. Although the Contrilctor brought in a special crew and took cxtra eff0l1 to constmct the hituminous driveway, some mil10r settlemel1t occurred after the spril1g thaw il1 2005. It is URS opil1iol1 that the level of quality pcrformcd by the contractor met il1dustry standards and that the cOl1tractor should not be penalized for the minor settJcrnents \vhich have oecurrcd. Thcse areas \vere patched \vith hituminous fines during the spring of2005, however, additional Inlnor settlemcnt continued to occur over the remainder of the summer 2005 and spril1g of 2006. includil1g a small hole near the garage apron. The hole near the apron \vas filJed \vith a small amount ofbiturrllnous mix hy the URS inspector in May, 2006, however, 110 addiliol1al patching has occurred sil1ce the spril1g of 2005. The approximate driveway dimel1sions ore 38' dcep and 60' wide (at curb) totalil1g 2280 SF or approximately 250 square yards. The Hat slope area which has experienced the settlemcnt areas represcnts approximately the northern 60% (36') of the driveway. TIle southern 24' is functioning satistactorily hom a drainage perspective_ Based upon our field review last fall and this spring, we would not reconnnend any reconstruction work for the s-OUthC111 24' of the driveway. Mark Lynch, frank Ticknor and I met with the homco\vncr May 18th to review the situation again and discuss options. The follO\ving are the options for the City to consider:
