We under- <br />' stand the roadway will be asphalt surfaced and designed for an <br /> equivalent 18 kip axle loading. <br /> Bridge Improvement: The repair will consist primarily of recon- <br /> struction of the abutment mertbers together with the bridge decJc <br /> members as required. The bridge center supports will probably rot to <br />1 replaced. <br /> Ponds: Three ponds to retain surface runoff and two ponds for <br />' fresh water storage are proposed. Structures will be earthen and <br /> typically 20 feet deep. A hillside slope method of construction will <br /> generally be used with cut and fill depths ranging to maximums between <br /> approximately 10 to 25 feet. Water depth will typically be a maximum <br /> 15 to 17 feet with the exception of runoff pond #3 which will only be <br /> about 5 feet. Fresh water prods are anticipated to have a relatively <br /> constant water level, whereas the runoff ponds will fluctuate. <br />' Potable Water Plant: The system will consist of a 150,000 gallon <br /> water storage tank and a small water treatment plant.

Loadings are assumed to be relatively light. <br /> Railroad Spur: The spur will consist of an approximate three- <br /> quarter mile alignment along the north bank of the river to service <br />, <br /> <br /> <br />
