~FT, i-EEANS.AS. TCCSN cale of tie situation at high water, we could simply construct this line as needed directing it into the river in the shortest distance, but because {. pumping station must be built, it vlll i figure out that you should carry this sewer some distance down stream be- fore tufnlng 1t into the river All these problems can oe worked out after more data IS collected
 Regardless of what plan may eventually be adopted for flood pro- l lection, it will be necessary to take care of the sanitary sewers, and in orde2' to do so, q pumping plant will 1 have to be constructed This plant had best consist of two pumps of about IS to 20 inches in diameter each, and would suggest that they be driven l by motor, 15-hoIsepoNeT for each one, about 400 revolutions per minute, 2,200 volts, 3 phase, 60 cycle, squirrel cage, automatic control, etc, to cost, erected, s9,000.00; necessary pump house and pump well, complete, %3.- { Sl2,0O000.
 ''To return to the flood protection problem: The situation is very well 1 discussed ii the newspaper article above referred to, and we will now
 merely give you some approximate figures covering the cost of the dlf- ferent plans.
 Must Build Levee.
 "Any plan adopted means the con struction of levee in the vicinity of | T-ll No, as to the quantities required in this bilitv of pumping material from the river by hydraulic process, and filling the entire space between Second ave nue and the river, placing it three feet above extreme high water, rais- ing the houses up to 9 point above the new grade, thus entailin@ no damage except the expense attached to rais- ing these houses. We believe this material could be gotten in place at 20 cents or less per cubic yard. This levee would operate to exclude the river water, and if nothing else were l done, would give considerable relief. To place in this levee flood gate of sufficient size to carry off, properly, all of the run-off that reached this point or that would have to be pro- vided for in a drainage ditch, would certainly cost not less than S25,000.00, 1 but to provide a culvert or flood gate | of the size that is now found under Second avenue, would cost probably only one-fifth as much. These are pure guesses. The storage capacity | below, contour 90 of 4,S00,0O0 gallons, means about AZ of an inch n-off in an entire area of 2,250 acres. The point advanced here is that if the 1 levee is constructed. and a small flood gate placed therein, the condition 1 would never be worse than at pres ent, and often much better dependent | upon the amount of rainfall during i the periods of high water
 l "Considering next the question of pumping plant to take care of this storm run-off from the entire area in- volved, means an expense of S14O, 000.00 for steam plant and $780, O0O0O for an oil plant, further, with coal at $2.00 per ton and oil at ? cents per gallon, an expense per hour for fuel of S5.40 and $500, respec- lively. To the cost of this pumping plant must be added the levee and the S25, 100000 culvert, so as to avoid the expense of pumping when the river is at low stage.
 Bayou Bartholomew Plan.
 "We now consider the plan of build ing canal southeast to Bayou Bar tholomew, which, upon it's face, ap- pears to be the logical thing to do, as it will not only take care of the sit uation for all time to come, but will do away with most of the mainten- ance expense, and will at the same time, no doubt, afford benefits to the lands through which it will go, which benefits it would seem well to place at minimum amount, because the 1 city could well afford to pay the greater part of the expense.
 1 "I do not have enough information regarding grades and high water ele vations in Bayou Bartholomew to de- termine definitely what sized ditch is required, because, as you can readily understand, if the fall is two feet per mile, the ditch will not have to be as large by a considerable amount as l if the fall is only one foot per mile; however, the cost of this whole con- | l note, however, in this connection, that you suggest the necessity of con structing covered culvert within the
  where in the neighborhood of 2,500 lin. feet of construction. Here, too, l find lack of information as to the drop, or fall, that can be obtained for instance. fit is two feet per mile, it will require only about two-thirds as much culve1t as if the, fall is only one foot; per mile. Assuming that you can get two feet per mile for this distance, proper outlet should not cost more. than $100,000.00, making the total cost for the. line to Bayou Barth holomew about $150,00000. Re garding this concrete culvert, it might prove advisable to build only 9 small portion at this time, because if the ditch is constructed the culvert could later be placed therein as re- quired, or as the territory becomes built. up and developed. You must add to this scheme cost of levee at Mallory, Ditch without a culvert.
 "None of the figures given take into consideration the question of cost of the right way, as | have no data which will enable me to estimate the same. E
