Ms. Sandy Emrich ~J September 29, 1983 Page 2 • _.. - In order to construct the cut and fill slope (1.5:1) according to the regulations, a large area would have to be disturbed. A scraper road, which is only tem- porary, does not warrant this type of disturbance. - Road construction in this area is not only much easier (ie brush removal, topsoil removal) but much safer to construct. Topsoil removal on the previously proposed road right of way would have been on side slopes ap- proach 60% which makes fora potentially dangerous situation. - Stability of the road located in the drainage will be greatly increased over previous side hill location. - This road location will greatly enhance reclamation operations. (2) Location This access road is not located in a channel of an ephemeral stream draining a watershed of at least one (1) square mile. The watershed is only 191 acres. Please see Section 4.05.3 attached. • (3) Design and Construction A great deal of the road will have to be field designed. In general dozers will brush the area starting at the upper end of the hill and push the brush down the hill. Scrapers will then remove topsoil in the same manner. Centerline of the road will generally follow the centerline of the drainage. The width of the road top will be ap- proximately 20 feet. Alignment as shown on the Profile, will not meet the grade require- ments as set forth in Section 4.03.2(3)(a)(i). In order to meet this 10% overall grade requirement numerous swithbacks would have to be made. A road of this type does not warrant these construction techniques and therefore PCC requests an alternative design as shown on the Profile. There should not be any cuts or fills along this proposed route. The only cutting will be the topsoil salvaging operation. (4) Drainage Access road drainage will not be designed to meet the 10-year, 24-hour event. Here again, the nature of this road is not that of a haulage road and should not be treated as one.
