PERMEABLE PAVEMENT WITHIN CRY RIGHT-OF-WAY <br />REQUIRES APPROVAL BY THE CCTV ENGINEER WHEN PLACED <br />BENEATH ATRAVELED WAY. THESE GUIDELINES PROVIDE A <br />MINIMUM DEPTH FOR THE HYDROLOGIC PERFORMANCE OF <br />THE PERMEABLE PAVEMENT. THE STRUCTURAL CAPACITY OF <br />PAVEMENT SECTIONS WHEN SUBJECT TO VEHICULAR LOADS <br />DEPENDS ON SEVERAL FACTORS AND MUST BE DESIGNED BY <br />A LICENSED PROFESSIONAL ENGINEER. <br />2. LONGITUDINAL SLOPE, 0TO 5% MARK. FOR PERMEABLE <br />ASPHALT,8% MAX. FOR PERMEABLE CONCRETE. <br />3.
