(Stations 68+00 to 71+JO) - 300 feet of "soft berrning.'! This section would cross t~e nort~1 0dqe of the town park. To raise the high ground a, average of 1.5 foot, the park would be recontoured wittl a berm that was consistent with the use o~ the site for recreational purposes. ht t~e east end natllral ground is already 2 feet above t~e 100-year flood e:evation. so the recontouring would be tapered to tie into that natural ground (See cross-section A-A). Alternative B This alternative includes the reconstruction of the eKisting levee system which is severely eroded at a number oE locations. The levee along the north riverbank would be c()ntinued east to the southeast cor~e~ of the Dolores ~]ate~ T:~eatment Facility; thence, it would turn 909 to the north to tie into the south edge of Eighway 145. A levee description is as follows: (Stations 66+00 to 78+40) - 1240 feet of existing levee will have to be reconstructed. The heiaht will average from 10.5 feet along the town park; 4 feet adjacent to the new water treat~ent plant~ and 8 feet alc)ng the water treatment pan6s (See cross section B-B:.
