"Encroachment" means the placement of uses, materials, fill, or structures into the regulatory floodplain in a manner that impedes or adversely modifies the flow conveyance capacity of the channel and/or regulatory floodplain of a watercourse.
A. An equal degree of encroachment is the standard applied to the evaluation of the effect of an encroachment within the regulatory floodplain with respect to the degree in which flood water heights or flow velocities may be changed as a result of the encroachment and assumes that all property owners on both sides of the watercourse are provided with an equal right to encroach to the same degree within that reach of the watercourse and modify the flow capacity within the floodplain including increasing the flood height or flow velocity.
B. Since the factors affecting hydraulic efficiency are usually not uniform within a reach, this standard may not result in equally measured distances between floodway limit lines and the regulatory floodplain boundaries of a watercourse.
