Augustalee Water And Air Quality Protection The Augustalee team has taken a proactive approach to water and air quality for the development, considering the project’s density and its proximity to the region’s most important water features – Lake Norman.

| Cornelius Bromont, the developer, views this project as a partnership with the Town of Cornelius and Mecklenburg County, with the goal of helping provide a well designed and well implemented project that will minimize impact on the surrounding environment and help enhance the neighborhoods around Augustalee. Through the use of innovative stormwater technologies and approaches, the site will significantly reduce sediment and nutrients from the stormwater runoff, so they are substantially lower than the levels that are typically required. And through the use of advanced air filtration and energy-saving technologies, the project will minimize air pollution – in fact it will represent a net gain for the region’s air quality. Two thirds of the 7,200 parking spaces will be underground to reduce impervious parking space. The water quality systems being considered for this project are industry-leading products, some of which are not currently required by County stormwater standards but have strong track records on previous projects throughout the U.S. |
 • During construction all stormwater runoff and sediment-laden water will be maintained on the project site through the use of temporary diversion ditches that are routed to onsite sediment riser basins (earthen or stone enclosures) for treatment. (Click on thumbnail above to see enlarged image.) • The denuded portions (bare earth) that cannot be drained to a basin will be bordered with silt fences. • Temporary gravel construction entrances will be placed at each location where construction traffic will enter the public roadways to help control sediment from leaving the project site. • At the conclusion of each phase of construction, all denuded areas will be stabilized to help prevent sediment-laden water from entering natural waterways within the vicinity of the construction site. This stabilization will include seed and straw, erosion control blankets or turf reinforcement mats, final surface (asphalt, gravel, concrete), etc. • The final project will capture stormwater runoff that falls on the site through a closed collection system. Depending on the area, the stormwater will either be detained and treated by an above-ground wet detention pond or an underground detention system with a structural sand filter for treatment. • The water treatment systems will be designed to achieve 85% Total Suspended Solids (TSS) removal and 70% Total Phosphorous (TP) removal – standards higher than required levels.

Air Quality Details • Service vehicles including garbage and trash pick-up for the central residential-retail core will be entirely underground to minimize odors and exhaust fumes  • Exhaust air from vehicles in underground parking garages and driveways will be filtered through electronic air filters to remove as much pollutants as possible prior to expelling into the outside air.  • The planned additional lanes which Cornelius Bromont will add to I-77 and U.S. 21 will reduce vehicular congestion and the air pollution caused by idling vehicles in congested traffic.• The site will be regularly watered during construction to minimize dust in the air. • Car pooling, van pooling, biking, walking and electric vehicles will be encouraged to reduce the use of single-occupant vehicles traveling to, from, and on the site.
