Pretty sure all of that land has been approved for clearing, building commercial/residential property. Its a shame since there are some nice trails throughout those trees.
Lower Eastlands is all currently under development consideration by City of Calgary. If you give a sh$t now is the time to speak up and tell the city to keep it as a big piece of undeveloped green space.
Cool little edit. Represent East Lands!! To bad that one day some stupid retail village will bulldoze its way in there. Shame on losing this huge green space.
