Woolan's Park Wetland Bank Part B: Appendix 1 Critical Connections Ecological Services, Inc. January, 17th 2012 Appendix 1: Design and Construction Plan Requirements Definition of Existing Conditions Page 1 of 3 Existing Conditions: Woolan's Park is a 17.62 acre city park that is located at the north end of Diane Street in the SW 1/4 of the NW % of Section 4 of Township 31 North, Range 22 West, Lino Lakes, Anoka County, Minnesota (Appendix A, Figure 1). Located within the Woolan's Park boundary is a large wetland complex that covers much of the park itself along with several upland oak and aspen woodlands. Parts of the large wetland complex are classified as palustrine emergent saturated flooded wetland (PEMBd; Circular 39 Type 2), palustrine emergent seasonally flooded wetland. (PEMC; Circular 39 Type 3), and palustrine emergent semipermanently flooded wetland (PEMF; Circular 39 Type 3). Areas bordering the uplands throughout the wetland complex consist primarily of a PEMB wetland fringe that is dominated by reed canary grass (Phalaris arundinacea) and Canada blue -joint grass (Calamagrostis canadensis). The outer fringe of this wetland transitions to wetter palustrine emergent hydrologic regimes that include PEMC and PEMF. The area of PEMC and PEMF wetland occur further out in the center of the wetland complex and is dominated primarily by wiregrass "sedge (Carex lasiocarpa). Site Topography: Overall the site is relatively level with only a few feet of elevation change across the property. The topography of the site ranges in elevation from 902.0 in the wetland areas to 906.0 in the oak uplands (Appendix A, Figure ,2) A ditch .is'. present off,- siter along the northwestern property boundary. In general water on -site drains to the southwest toward Pin Oak Lake through the wetland complex that connects the two areas. Existing Easement: ., A natural gas pipeline is located within the north end of the park and extends from the east to west boundaries of the park. The pipeline is owned and maintained by Minnesota Pipeline Company, LLC. The easement over this pipeline covers approximately 1.16 acres and is 60' wide. This pipeline easement is maintained by periodic brushing of woody vegetation. Current Land Uses: Current land uses surrounding Woolan's Park include: residential housing immediately to the south, large lot residential to the east, woodlands to the north and northwest, and a large wetland complex to the southwest that connects to Pin Oak Lake. Within the watershed surrounding the city park, residential housing is located primarily to the south and southwest. To the north and east is more open space including wetlands, lakes, and woodland /forest areas with less residential housing. Agricultural uses can also be found within a half of a mile from the site but is not a dominant land use of the area. • •
