Mr. Rabaut. Please explain this new start. General FLEMING. This is a local protection project for the town of Socorro. The total cost of the project is $4,030,000, of which the Federal cost is $3,700,000. Local cost is $330,000, $60,000 in cash and $270,000 in other costs. 1.2 to 1 is the benefit-to-cost ratio. It is a good project.

The problem here develops because the arroyos coming down from the hills to the valley itself, the drainage structures have been limited at the bottom and to what was necessary to handle the irrigation problem, and when the floods come down, as Mr. Jensen says, when the rain hits you get this tremendous runoff, very quickly. There is no outlet from the arroyos.

The project consists of putting in a collection drain around both sides of the town which will keep runoff from going into these arroyos which have no outlet at the bottom, and we will get the water back into the river.

Mr. RABAUT. When will you award the first construction contract !

General FLEMING. We plan the first contract on this to be awarded in the fourth quarter of the coming fiscal year. Mr. RABAUT. Questions?

Mr. Magnuson. How much is the relocation cost for this total project?

General FLEMING. Relocation cost is $479,000.
Mr. MagnusON. Is that primarily railroad or highway!

General FLEMING. There is one railroad, raising the grade, and the bridge. A bridge must be provided. The others are utilities, perhaps some waterlines, electric light lines.

Mr. MAGNUSON. Is the railroad and bridge a big item?
General FLEMING. Yes ; $283,000 of the total of $479,000.
Mr. MAGNUSON. That is all, Mr. Chairman.

Mr. JENSEN. To give you an idea of the siltation problem they have in this area, I was there some 5 years ago and drove from Albuquerque to Socorro.

The road on which we traveled was on top of two-story buildings where a town of several hundred people had been 50 years ago, and it was completely covered up. Two-story buildings were completely covered. There was no sign of a building or anything else.

Off the record. (Discussion held off the record.) Mr. JENSEN. When I saw this situation in Socorro some 5 years ago, I was a stanch advocate of this project being built.

I was quite surprised when I learned, however, that the participation was $330,000 out of a project cost of $3,700,000.

Of course, this project was started and authorized before the committee took the position that henceforth we would expect more local participation. I believe this was some 3 years ago. Many of these projects were almost entirely for local benefit.

I cannot understand why the local participation is not greater than it is on this project because the benefits are almost exclusively local.

Mr. RABAUT. Is the local contribution on this project fixed by law?

General FLEMING. Fixed in the authorization act, sir. We have the usual ABC cooperation, furnishing lands and rights-of-way, and there is a cash contribution specified of 1.6 percent of the estimated construction cost. Actual cost to the town was estimated at $330,000. Mr. JENSEN. You will have a siltation problem there, General. Mr. RABAUT. On what basis is this 1.6 figure?

General FLEMING. I have not been able to get that, sir. I will furnish it.

(The information requested follows:)

The local contribution of 1.6 percent of the actual cost of construction incurred by the United States as fixed in the authorization act is compensation for the enhancement of land values. This is based upon the proposed increased utilization of about 53 acres of land for residential, commercial, and public use and in addition there are about 20 acres presently used for residential purposes which could be put to higher residential use if flooding were eliminated.

General FLEMING. I believe it is land enhancement.

Mr. JENSEN. Of course, in all these dams that we build in that area we provide a certain part of the reservoir for siltation deposit. Do you know what this dam provides? What effect do you think the siltation problem will have on this channel which you are now constructing?

General FLEMING. The channels are being designed to minimize the siltation problem. We estimate we will get siltatiton just as you get siltation in any stream in that area.

The cost of maintaining, phased out over an annual period, is the annual maintenance cost.We estimate that will cost the city after it is built about $17,000 to $18,000 a year just to maintain the channel after construction.

Mr. JENSEN. You mean to dredge out the silt?
General FLEMING. Yes.
Mr. JENSEN. If that is all you have to spend I will be surprised.

TWO RIVERS RESERVOIR, N. MEX. Mr. RABAUT. Two Rivers Reservoir, $3 million. Insert pages 128 through 132 of the justifications.

(The pages referred to follow :)



LOCATION: The project is located about 12 miles southwest of Roswell, Chaves County, N. Mex., at Rio Hondo
river mile 37 and consists of two earthfill dams which will form one reservoir; Diamord "ADam on Rio Hondo
and Rocky Dam on Rocky Arroyo, a tributary of Rio Hondo. Rio Hondo is a tributary of the Pecos River.
