Review File: 7214 167th Terrace <br />Variance Request Follow-up Report <br />July 25, 2017 <br />Page 2 of 2 <br />ponding because portions of the lawn had died and evidence of a pump that was <br />disabled at the lowest spot in the lawn. The 30 days prior to our site visit had <br />normal amounts of precipitation. <br />I appears that the wetland boundary has been modified because of past lot grading <br />and lawn practices. It would be difficult to determine who did what and when, <br />though. <br />Staff has used GIS to look at aerial photographs and contours of the site. The photographs are <br />from 2003, 2006, 2008, 2011, 2014 and 2016. They show the progression of home construction <br />in this area. The 2008 photo shows that no homes had been constructed on this lot or the ones <br />sharing the common lot line. The 2011 photo show that two homes had been constructed on <br />adjoining lots. The 2014 photo shows that there is a home on this lot and each of the adjoining <br />lots. <br />The contours are from 2003 and 2011. The 2003 contours are prior to construction of the <br />subdivision and correlate with the approved grading plan. The 2011 contours are after the <br />grading was completed and the project sat dormant for several years. Comparing the grading <br />plan with the 2011 contours indicate the 874 contour has shifted 10 to 20 feet into the wetland. <br />The 874 contour was shown at the outside edge of the wetland on the approved grading plan. <br />The planning commission was clear in stating that the wetland must be preserved if Anoka <br />Conservation District and BWSR determine that is still functioning. Based on the field <br />observations, wetland vegetation, soils and hydrology are present on this lot. The lots to the <br />north east appeared to have been filled and leveled up to the common property line, the <br />vegetation was predominantly sod. We did not go onto those lots to look for wetland indicators. <br />Testimony at the public hearing indicated that the stormwater pond occasionally fills up and <br />flows onto the subject property which is what was predicted by the stormwater model for the <br />development. <br />
