7. MITIGATION RECOMMENDATIONS
State recommended measures and fees required to mitigate project specific traffic impacts. Traffic impact
fee shall be calculated from the Edmonds Road Impact Fee Rate Study Table 4 (attached) and as identified
in ECDC 18.82.120, except as otherwise provided for independent fee calculations in ECDC 18.82.130.
