Green Infrastructure Guidelines

These guidelines were prepared in conjunction with the Monocacy Creek Watershed Act 167 Stormwater Management Plan Update (2017). The guidelines are important for reinforcing the message of the outstanding natural resources present in the Lehigh Valley and their wide variety of essential services and benefits to local residents and visitors, describing the best practices available for community and site design to preserve or enhance those resources, and defining improved stormwater management site design practices to better mimic natural systems. The guidelines provide 1) an overview of green infrastructure at a regional scale and the associated benefits and 2) engineering guidance for site-specific stormwater management practices to help designers understand and comply with the water balance and green infrastructure provisions of the updated Act 167 Ordinance.
