During the right-of-way acquisition process, concessions were made <br />with individual property owners to facilitate the purchase of right-of-way. <br />Amendment No. 7 is to revise the drainage design within drainage basin 66B (66th Avenue between 61St <br />Street and 65th Street) from a single centralized detention facility to two (2) wet detention ponds.
