Porous Gravel<br />

Designing for Maintenance<br />

Recommended ongoing maintenance practices for all BMPs are<br />

provided in Chapter 6 of this manual. During design, consider<br />

<strong>the</strong> items provided on BMP Fact Sheet T-10 as well as <strong>the</strong><br />

following:<br />

• The surface of porous gravel pavement may rut more than<br />

desired. If this is a concern, consider an interlocking plastic<br />

cellular paving product (or similar product) to better<br />

stabilize <strong>the</strong> wearing course. Discussion on this product is<br />

provided in BMP Fact Sheet T-10.5 (Reinforced Grass).<br />

Benefits<br />

• Low cost compared to o<strong>the</strong>r<br />

permeable pavements.<br />
