*[[Permeable paving]] is an option for parking lanes and sidewalk. However, permeable pavers are susceptible to clogging if receiving runoff drainage from adjoining asphalt roadway. Avoid permeable pavement for high traffic travel lanes. Pervious concrete or porous asphalt are options for bike lanes.

*Perforated pipes are suitable for collectors with very limited space, particularly where there is no routine landscaping maintenance. However, adequate pretreatment such as grass swales, extended sump catchbasins, or prefabricated units must be provided.

*Curb extension bioretention is not a common practice for collectors, but they can be used in some cases to reduce pedestrian crossing distances at intersections

*Dedicated parking lanes or parking lay-bys can be converted to permeable pavers. The permeable parking lane can be designed to accept only the rainfall that falls on it or it can take runoff from up to two additional lanes.

*Attractive [[stormwater planters]] and [[permeable paving]] sidewalks are appropriate for high density areas and where business districts expect an enhanced or signature streetscape.

*Street [[trees]] can be supported with LID options by providing root volume space in [[bioretention]] practices or with sidewalk support systems. Permeable sidewalks allow air and moisture to reach tree roots, which in turn reduces sidewalk buckling from roots pushing through the surface.
