This will be a.t a relatively small <br /> <br />oost and can be so handled with land leveling work as to little affect <br /> <br />total oost. <br /> <br />The~e is very little evidence of wind erosion in the area and little <br />effec~ <br />effect need be antioipated following land olearing. Not muoh/fromwater <br /> <br />erosion is to be observed throughout the project area notwithstanding <br /> <br />gradient of slopes, and oonditions affeoting this might be expected to <br /> <br />be little changed after land leveling, because of the nature of the sub- <br /> <br />soil to be exposed. Most danger of erosion is to be observed in the <br /> <br /> <br />southernmoat:pa.rt of the project. The. soils here are heavier, made'up <br /> <br />,:' more of fin.er particles. 1:Iere, nearer to the river, the arroyos are <br /> <br />larger, with more gradient and larger volumes of flood water pour through <br /> <br />their cutbanks. It should be kept in mind tha.t such results of erosion <br /> <br />as are apparent are the effects of nges. With ngrioultural development <br /> <br />most of .thisoould be prevented. <br /> <br />There are no large qreas of very seriou.s weed infestation. Some bad <br /> <br />patches of bin.dweed are observed in the partly irrigated lands of the <br /> <br />northern part of the project area, espeoially where cultivation. has been <br /> <br />neglected or abandoned with lack of water. It is not believed that final <br /> <br /> <br />land development surveys and estimates will show much need for weed <br />
