===Urban Cross-Section===
+
Characteristics specific to the urban cross section include:
+
*Parking zones are often underused
+
*Residential boulevard space is the easiest to modify and use for stormwater management compared to other street types
+
*Utility lines may be in separate or shared trenches
+
+
Typical LID opportunities Within the roadway:
+
*Curb extension bioretention is a good method for
+
calming traffic and using underutilized parking zones
+
*Due to low speeds and low traffic, permeable pavement can be used for the roadway from curb to curb
+
+
Within the boulevard:
+
*Boulevard bioretention can be easily incorporated into a rural to urban upgrade by allowing for stormwatertreatment within the boulevard space
