Tanglewood Hills HOA is a homeowners association located in Batavia, Illinois within Kane County. Tanglewood Hills HOA is a beautiful neighborhood comprised of 10,580 homes just east of the bustling shopping centers of Randall Road. Amongst the homes of this sprawling community are twenty-seven common spaces covering sixty-one acres intertwined with walking paths which have been restored, or are being restored, into ecologically diverse native Illinois prairie ecosystems.
Since 2011 Pizzo and Associates operates as the responsible steward of these valuable man-made native spaces. Our stewardship crews of field trained ecologists remove invasive plants that pose a threat to native plant populations through regular visits built around a strategic plan of conservation and establishment. The Tanglewood Hills HOA Board encourages us to utilize all the tools at our disposal to ensure the success through stewardship, yearly prescribed burning, invasive tree and brush clearing, and native seeding and planting operations. We diligently work with the board and homeowners to transform disused common areas, as well as increase the ecological diversity of existing units. By maintaining these areas to a high ecological standard, we also increase the effectiveness of the neighborhoods storm water management. The sixty-one acres of native plant populations help control runoff, increase ground water penetration, decrease flood risk, and filter out more pollutants than otherwise would be.
Tanglewood Hills provides a compelling look at how the systems required for human habitation like storm water management can be designed to accommodate native green spaces for both flora, fauna, and people to flourish. By utilizing the natural drainage patterns of the landscape and building new detention, retention, and dry bottom basins to help direct the flow of water, the changes in hydrology caused by human development has created a variety of environments in which native plants can thrive. Across the sixty-one acres a variety of habits originally found amongst Illinois prairies have been replicated. These twenty-seven units’ range in size from one to seventeen acres, and are comprised of seasonal wetlands, dry upland mesic prairies, ephemeral woodlands, wet sedge meadows, oak savannas, and grasslands. Each unit is home to between sixty to eighty different species of flora native to Illinois prairies, which in turn provides valuable habitat to a wide range of native North American animals and insects whose find refuge in these green oases.
