Main streets are set in areas with high density commercial, residential, and mixed use and are typically focal points of the community. The buildings have small to no setbacks and create a continuous wall along the street. They offer an opportunity to incorporate beautifying green infrastructure, but they are also a challenge for designers owing to the multiple demands of street parking, street trees, business access, above and below ground utilities, pedestrian accommodations, and vehicle movement. Depending on age and prominence these streets may have been reconstructed multiple times and have infrastructure legacy issues like abandoned utility lines. Other characteristics include:
*Street parking is typical and may have frequent turn over and is necessary for local business.
*ROW dimensions will vary greatly depending on the age of the community.
===Typical LID opportunities===
Multifunctional LID practices are favored where there is a premium on space. Bioretention planters can serve as both the landscape amenity of the street and treat stormwater. Permeable pavement serves as a treatment practice but is also a hardscape for parking and pedestrians.
'''Within the roadway:'''
*Curb extension bioretention can be used as traffic calming features and reduce pedestrian crossing distances.
'''Within the boulevard:'''
*Due to the high profile of this street type, they are maintained on a frequent basis and provide the most appropriate setting for an aesthetic bioretention feature.
*Street trees are high priorities for this road type and LID options should support or incorporate them by providing root volume space in bioretention practices or with sidewalk support systems.
