Big Island Nature Park Management Plan November 2011 ____________________________________________________________________________ 27 Two management zones have been designated within the Park - a Recreation Area and a Natural Area, with differing characteristics in terms of allowed uses and maintenance practices. The need for visually defining the boundary between the Recreation Area and the Natural Area may become more acute as public use of the Park increases. For the visiting public, low impact signage along the boundary may be considered; however, other options will be explored if and when the need arises. It is incumbent upon the City to ensure that its employees and agents can readily identify the limits beyond which certain maintenance practices may not be employed. At this time there are no plans to expand the Park via acquisition of additional property. The only abutting property is owned by Three Rivers Park District as part of its Big Island Regional Park. Mapping, Survey Needs An ALTA/ACSM Land Title Survey of the property was completed for the Minnehaha Creek Watershed District in 2006 to facilitate and document the elements of the Conservation Easement. The survey includes 2-foot contour topography, delineated wetland boundaries, and floodplain boundaries, as well as the location of then-existing buildings and structures, walking trails, surface evidence of utility lines, and other man-made features. Electrical wiring was buried in 2009(?) but has not been accurately mapped. Other buried infrastructure includes remnants of a water distribution system which is currently not in service and not mapped; and septic system components, also not in service, for which fairly detailed design and location data is available but not surveyed. Americans with Disabilities Act (ADA) Requirements (To be researched and addressed) Buildings At the time of City acquisition the site contained 13 buildings and one house trailer in various states of repair, depicted and numbered on the ALTA survey, as follows: 1) South hill picnic shelter - wood frame, 30‘x50‘ 2) South hill toilet building - wood frame, 12‘x12‘ 3) Northwest picnic shelter/toilet building - wood frame, 30‘x75‘ 4) Entrance office building - wood frame, 10‘x10‘ 5) Storage building - concrete block, 30‘x28‘ 6) Storage building - concrete block, 24‘x26‘ 7) Storage building - concrete block, 22‘x24‘ 8) Shed - wood frame, 16‘x16‘ 9) Main dining hall - wood frame, 90‘x100‘
