She further stated that much of this water was coming off of the new subdivision to the north (The Meadows) which should be taking care of its own drainage. A review of The Meadows drainage plan provides for a large retention pond located just northwest of Mrs. Asmussen's property. Roughly on half of the drainage from this subdivision is designed to be drained into this pond through catch basins placed along Helium Street. The southernmost of this series of catch basins is located 160 feet north of the plat boundary with Pondvale Estates. Therefore only the southernmost 160 feet of roadway from the Meadows subdivision should flow into the pond located on Mrs. Asmussen's property. On March 21, 2007 \ visited the site and found all the catch basins on Helium Street to be open and clear of debris. The final lift of bituminous has not been placed on Helium Street, so that the front of the curb flange is about one inch higher than the edge of the bituminous. Almost all of the snow and ice had meited from the large storms experienced two weeks ago, except for the last 100 feet of Helium Street from the Asmussen pond. I noticed a layer of ice covering the concrete curb and extending six inches to a foot onto the bituminous pavement. It is my opinion that what Mrs. Asmussen observed was indeed all of the drainage from the area destined to flow into The Meadows detention pond was flowing into the pond on her property. The reason for this was that the catch baslns were not functioning because the water was not the flowing along the concrete gutter but rather was flowing along the edge of the bituminous pavement or the edge of the snow bank. ] believe that this street was not plowed to its fuIJ width so as to prevent chipping the edge of the exposed curb, and as a result the several feet of snow bank compressed into a sheet of ice which froze the curb line shut. Some evidence still remained at the time of my site visit. This situation should not reoccur in the future because of the fact that the final lift of bituminous will be placed prior to next winter and that Helium Street will be plowed to its full width making the catch basin functional. I have called Mrs. Asmussen and discussed these fmdings with her. a5WI In/tV
