Pervious Pavement<br />

with Infiltration<br />

Pervious pavement is an infiltration technique that combines stormwater<br />

infiltration, storage, and structural pavement consisting of a permeable<br />

surface underlain by a storage reservoir. Pervious pavement is well suited<br />

<strong>for</strong> parking lots, walking paths, sidewalks, playgrounds, plazas, tennis<br />

courts, and other similar uses.<br />

Variations<br />

• Porous asphalt<br />

• Pervious concrete<br />

• Permeable paver blocks<br />

• Rein<strong>for</strong>ced turf/gravel<br />

Key Design<br />

Features<br />

• Follow soil infiltration testing<br />

protocol (Appendix E) and<br />

infiltration BMP guidelines<br />

• Do not infiltrate on compacted<br />

soil<br />

• Level storage bed bottoms<br />

• Provide positive stormwater<br />

overflow from bed<br />

• Surface permeability >20”/hr<br />

Site Factors<br />

• Water table/Bedrock<br />

separation: two-foot min*.<br />

• Feasibility on steeper slopes:<br />

<strong>Low</strong><br />

• Potential hot spots: Not<br />

without design of pretreatment<br />

system<br />

Benefits<br />

• Volume control and<br />

groundwater recharge,<br />

moderate peak rate control<br />

• Dual use <strong>for</strong> pavement<br />

structure and stormwater<br />

management<br />

Limitations<br />

• Pervious pavement not suitable<br />

<strong>for</strong> all uses<br />

• High maintenance needs<br />

* Four feet recommended, if possible<br />

**Applicable with special design considerations.<br />

***Pretreatment <strong>for</strong> TSS is recommended.<br />
