Page 4 of 4 <br /> • give the impression that the wetland line has moved upslope. I looked at the site this past week, <br /> augured three test holes down to 30 inches along the slope from high to low-from 60 feet upslope <br /> of the mapped wetland line down to the wetland line, and found approximately 24 inches of <br /> colluvium deposits over the native soils. I did not find any signs of redox in the colluvium layer <br /> which suggests to me that the site wetland line has not moved much if at all. However, some of the <br /> vegetation (reed canary grass and red osier dogwood) suggests that the wetland line has moved. <br /> To really answer this question we need to establish at least four transects and a minimum of 4 <br /> sample points per transect and get a very good look at soils. The vegetation on the site is quite <br /> typical and easy to identify: reed canary grass, red osier dogwood, common milkweed, Canada <br /> goldenrod, wild carrot, and Kentucky blue grass. Ground frost is all but absent due to the nice <br /> carpet of snow. I only found water at about 24 inches at the sample hole located adjacent to the <br /> former wetland line. Interestingly, there was about 24 inches of colluvium over the native soils and <br /> hydrology at the lowest sample point. <br /> Since the site was last mapped much of the upland areas have been developed so nearly all of the <br /> surface water runoff that once passed overland and into the wetland complex has been rerouted <br /> away from the site and now flows through a series of storm sewers and detention ponds. Sanitary <br /> sewer and water main construction may have likely interrupted groundwater flow as well. I would <br /> suspect that at a minimum that the site in question is actually drier than when first mapped in 1998. <br /> Finding ground water at 24 inches beneath the ground at the old wetland line did not surprise me. <br /> If we can meet at the site on Tuesday morning and do the work together I think we can get the line <br /> resolved quite quickly. <br /> One last item: Dane County is asking this be done because the land owner has a permit to <br /> construct a new multi-family building on the property. With the change in wetland setback criteria at <br /> the County level, the location of the wetland line must be verified for this reason alone. If we can <br /> work together to get this addressed before the ground frost shuts down the growing season that <br /> would be helpful to the County and to the land owner. <br /> Jim <br /> 1/28/2009 <br />
