Memorandum Zi.2llG CFAs OthIT TRUU IBM TO: Little Canada Mayor and City Council Members FROM: Lee Elfering, City Engineer DATE: August 23, 2006 RE: 2006 Street & Utility Reconstruction Wall Modification 2542 Morrison Street Background As part of the 2006 Street Improvement project a retaining wall was proposed to be constructed on south end of Morrison Street from approximately station 3 +00 to 4 +50. Upon completion of the wall the property owner to the north of the newly constructed wall expressed a concern that the wall was not extended onto her property where the boulevard grade was quite steep. The cross - sections contained in the plan set did not indicate substantial change in the boulevard grade along the property, however the cross sections only represent the grading at a few individual points. A site meeting was held with the property owner to view the entire length of the property and the resulting grading impacts. The existing boulevard was at a steep grade along nearly the entire property south of the driveway. While the grade along some areas of property did not appear to be changed by the construction, there were other areas that were. Based on the site visit it did appear that the wall should be extended to within approximately 10 or 15 feet of the driveway. As stated above, the existing boulevard grade whether impacted by the construction or not was very steep. It was discussed with the property owner that the City would look at extending the retaining wall to maintain the existing boulevard grade along the property, however if requested the wall could be constructed up to 4 feet high to flatten out the boulevard grade at the top of the wall. The additional cost would need to be paid by the property owner. They indicated they would like to look at that as an option, but made no final decision. Summary and Recommendations Due to impacts to the boulevard grades not shown by the cross sections we would recommend that the retaining wall be extended to approximately 10 or 15 feet from the driveway. The wall would be constructed to eliminate grade changes on the boulevard unless additional retaining wall is paid for by the homeowner.
