AMES construction <br /> removed the slide overburden material down to a layer of natural clay. They also re-established <br /> detention areas and created channeling to direct any stormwater to the detention. We have monitored <br /> the slide area and in the last week have had no movement at the top of the slide area and it has been <br /> two weeks since any movement has occurred at the bottom of the slide area. Based on having re- <br /> located the slide material and the stabilizations of the area we have ceased operations and will <br /> continue to monitor the area while we work towards an engineered solution. <br /> Pinyon-environmental has been contracted to do the survey and measurement of the area, due to a <br /> schedule conflict that work will be completed on Thursday, July 12`". <br /> We are including several photos of the area as of the end of last week and have included the <br /> quantities of material moved <br /> Please feel free to call if you have any questions, 303-434-1668. <br /> Thanks, <br /> ki qf'e" . <br /> Stanley C.
