' �i�1T�CY 1��I.IN�TIO�VS Data Form — Routine Onsite Determination Method October 8, 2007 Field Investigator: Ryan Freitag Date of Investigation: 10-8-2007, Project/Site: Located in Section 7 -T.117N.-R.23W. Hennepin County, Minnesota. Applicant: Dan Phipps 4064 North Shore Drive Orono MN 55364 Assessment Wetland Type Area Circular 39 Cowardin NWI Mapped Soils Vegetation 1 Type VII Pema Yes L36A Silver Maple, Green Ash Do normal environmental conditions exist at the plant community? ♦ Yes. The canopy of the wetland has not changed for several years. There is one mature Silver Maple on site,and several younger Silver Maple and Green Ash trees in the under story. These under story trees are approximately 25 years old. There is no grass/herb layer present. Much of this layer has been covered up by leaves from the trees on site. The grass/herb layer is present on an adjacent property, but that area does not have any canopy. Has vegetation,soil,and/or hydrology been significantly disturbed? ♦ No. The hydrology in this area would be the only thing that maybe questioned,but would need significant study. In looking at urban settings like this wetland is located in,I tend to assume that the hydrology has been slightly changed due to the added bounce from impervious surface. Also with homes all around this site,the effect of sump pumps would not be known unless further study is completed. Vegetation Percent of dominate species that are OBL,FACW,and/or FAC. Percent Basin Dominate Plant Species Stratum OBL FACW FAC 1 Silver Maple Emergent 75 Green Ash Emergent 25 Is the hydrophytic vegetarion criterion met? ♦ Yes Rationale: More than 50%of the composition of the dominate species from all strata are ranked as hydrophytic vegetation. 1 s2s��so°ro�V��tvu�,c�L�NC�E hMN 55s�6- �2�5��5$9�
