Sincerely yours, Pierre DuBois Managing Director THE DENVER POST — WEDNESDAY, JUNE 18, 1969 River Control Supported GREELEY, Colo. Sen. Gor- don L. Allott, R-Coio., Rep. Donald G. Brotzman, R -Colo., and Rep. Wayne N. Aspinall, D -Colo., have voiced their sup- port of flood control plans for Weld and neighboring counties in northern Colorado, Glenn Billings, a member of the Weld County Board of Commissioners, said Tuesday. The board, Billings said, is obtaining engineering estimates on work needed to protect the county when the South Platte and Cache la Poudre Rivers or their tributaries, including Boulder and Little South Creeks and the Little Thompson River, go over their banks. Estimates should be completed ,by next week, he said. GRANT SOUGHT , Weld County plans to ask the federal government for a grant of about $500,000 with which to buy bulldozers, draglines and other heavy equipment needed to strengthen the rivers, clean growth and debris from their channels and build dikes and levees. An additional $100,000 a year possibly would he needed for equipment replacement, Billings said. The county would furnish all the manpower needed for the flood -control project. Billings figured the cost to the county, on a 12 -month basis, at between $30,00O and $40,000 a year. Allott, Billings said, wrote him a letter in response to a re- cent query, supporting the idea of flood control but suggesting that Weld and other affected counties form a flood control district, then apply for a federal grant. He met Brotzman, who is from the 2nd Congressional District, In Brighton recently, Billings said, and received assurance of his support of a flood control district. Billings said he also talked with Aspinall, from the 4th Congressional District, in Washington and found him fa- vorable to the idea. .SOURCES SUGGESTED Marsh Anderson, chairman of the all -Republican board of commissioners, said both Aspi- nall and Jack Ware, administra- tive 'assistant to Allott, had sug- gested a number of government departments and agencies that might make grants. They included the Depart- ment of the Interior. Federal Water Pollution Control Admin- istration, Army Corps of Engi- neers. Soil Conservation Serv- ice, Office of Emergency Pre- paredness and Bureau of Rec- lamation, .The Weld County board, An- derson said, has met informally with Larimer County commis- sioners and plans to meet with commissioners from other coun- ties soon. Harold Anderson, no relation to Marsh Anderson, is the third Weld County commissioner. FLOOD CONTROL ON SOUTH PLATTE Record of meeting held in Brighton on May 20th, 1969, REA Building, 8:00 p.m. ; meeting was called at Brighton on May 20th with flood damaged land- owners on the Platte River from Adams and Weld County. The purpose of this meeting was to start action on river rechanneling to prevent the ex- tensive damage caused by high water on the Platte River. Mr. John Nalley, administration assistant for Rep. Don Brotzrnan; Major Higgins of Corp of Engineers; Mr. Valeroski from Washington, in charge of engineering on the South Platte waterways; and Mr. Miller, Colorado Water Conservation Board; were all in attendance. The laws which apply for such projects were explained to the 200 people in attendance. After lengthy discussion, it was voted by the group to organize a Flood Control District on the South Platte River. A steering committee of six, three from Weld County and three from Adams County, was elected. These committeemen are as follows: Al Krough, Bud Scott, and Bill Sharp of Adams County; and Elton Miller, Martin Allard, and Bob Sakata of Weld County. This committee is to look into the feasibility of this program and contact the proper authorities to get this river rechanneling underway. If anyone has any questions, they should contact one of these committeemen. // IN REPLY REFER TO: MROVG DEPARTMENT OF THE ARMY OMAHA DISTRICT.

Anderson Chairman, Board of Commissioners of Weld County Greeley, Colorado 80631 Dear Mr. Anderson: 27 May 1968 By letter of 29 February 1968 the City of Greeley and Weld County jointly made application to the Army Corps of Engineers for a flood plain information report for the Cache la Poudre and South Platte Rivers. 1 am pleased to inform you that the application has been approved and anearliy_.pr.L4.C,ity_.established for preparation of the report. However, at present we lack the necessary funds. We are hopeful that Congress will appropriate funds in the next fiscal year. We will delineate, for and supply to you within about 45 days, our requirements for the channel and valley cross sections which you agreed to furnish. This will afford you the maximum time for sur- veys and will permit us to develop the flood plain information when funds become available. Sincerely yours, HARtV C. 'I PP Chief, Engineering Division 1i01VG P nece, er 1067 Honorable Dorothy Martin Zahlk u Mayor of Greeley 901 7th Street Greeley, Colorado 80e31 hear Mayor Zabke: This responds to the joint County -City applicatios. of 2 '?ay 1367 for flood plain information along the Cache La PouOre and South Platte Rivers. Upon receipt of the application we recormended inclusion of priorities, Numbers 1 and 2, for the Cache La Poudre and Soutf Platte Rivers in and near Creeiey, in our program for Fiscal Year 1968, which ends 30 June 1%R. Ponds were not then and are still not available. Because of the laackt of funds we deferred action on the application. he did search our files for available data and reviewed the application for compatibility with currant policy - that is, providing flood plain information in urban arenas and where urbanization is iapinent. Our search yielded shout 2(? channel and valley cross sections distributed along the Cache La Poudre River in Weld County. We bad computed discharge rating curves for 15 of those sections by the slope area method and recently ce r,uted the discharge Pmt=aa- bility for the Greeley slige. For your use in preliminary planning we have plotted the locations of the 15 cross sections on the Windsor, i'4aacewcl1, Greeley and Kersey U. S. Geological Survey quadrangle maps. The amps were sent to old County by letter of S recent:er 1967, copy of the letter is inclosed. At the locations of the cross sections we have indicated the estimated elevation that would he reached by the Intermediate Regional Flood thus, I.R.E. El. 4787. The Intermediate Regional Flood approximates the 1 percent annual chance or 100 year flood. The cross sections are too sparsely spaced to provide a reliable basis for plottie the flooded area ofetl ine but they do previe indicators of the MB0VG g J ace her 19(7 Honorable Dorothy Martin Zahka magnitude of the flooding problem. Of the four flood plain information reports requested only Priority tier 1, covering the Cache La Poudre Rimer at Greeley, its the criteria for an urban area. A eunity east have had a population of at least 2,500 in the 1960 census or urbanization must be imeine nt. Priorities 2 and 3, covering the reach of the South Platte 'fiver in Weld County above the Cache La Fou<re's south, don't meet the population criteria for the several urban communities. Neither can the entire 35 mile reach be considered to he in the "urbanization is im hunt" category. Because of the good highway and railroad access, availability of utilities and the attraction Colorado has for industrialization it scams that some local reaches along the South Platte &eye freeley might h rated in the "urbanization is imminent" category if well supported. Priority Number 4 appears to he wholly aural with small chance of urbanization in the near future. We believe you will understand that funds and technical talent required to produce flood plain Information are limited. Flood hazards exist in some degree in almost every comity. It is necessary and only fair that flood plain information be provided first where the need is greatest. We suggest the following courses of action: a. Repeat an application for Priority Nenher 1 as soon as possible so that it ray have consideration for inclusion in the budget for Fiscal Year 1969. About I5 cross sections were surveyed by the Corps of Engineers in 1x51 along the reach covered in Priority tuber 1. These are inadequate in number for an accu- rate delineation of areas subject to flooding, and stream condi- tions have undoubtedly changed since the surveys were made. In the order of 6( channel and valley cross sections would be required for a armful delineation and we are hopeful that you could provide these. It is possible that two-thirds financial help for surveys may be available under rousing and Urbar, Development 701 planning grants. Within their extent sheets I and 2 of the 1962 topographic survey made by Continental Engineers Incorporated could be the basis for valley cross sections. However, the topography would need to be extended to elevations about 5 feet higher in order to encompass the flood plain. Where topography of the detail on the Continental survey is available we ere able to promote accurate flood area delineations. f!VC F December I') 7 itawrable Dorothy'Uirtirt 2abl a b. After a review of the potential for urbanization along the reach covered in Priorities 2 and S an application could be made for the specific areas that appear to fit the "arhanitu- tios is rent" category. i hope that the preliminary flood hazard information sup- plied herewith will he useful and that our long deliberation has not cussed inconvenience. sce.

Miller: The following is our text for a Flood Plain Information tudy application on portions of the Cache La I'oudre and South .rlatte Rivers in Weld County: The City of Greeley, Colorado, a municipal corporation, andacid County, organized and existing under the laws of the :state of Colorado, hereby request the Chief of Engineers U.S. 'Army, to undertake under Section 206, Public Law 86-645 (Flood Control Act, 1960) a flood plain information study La Poudr€ River valley in Meld County and portions Platte River valley in Weld County. These valleys adjacent to the City of Greeley. The study should of the Cache of the South are in part provide hydrological data and information relative to the identification of past flood height and inundated areas and the establishment of related flood study information that will assist the above requested areas to identify areas for flood plain zonnv these areas of imminent urbanization. .r. pan Greeley-►Neld C `1hty Flood Plain Study Page 2 LOCATION AND STATEMENT OF PROBLEMS The area to be covered by this study is established in four priority zones as follows: Priority tv.. 1: The flood plain areas of the Cache La Poudre River from the mouth of the Cache La Poudre r There it converges with the South Platte up through and including Sheep Draw. The City of Greeley has continued expansion into areas adjacent to much of this flood plain zone and urbanization is highly imminent. The City of Greeley has recently completed a major water grid system for the west part of Greeley that should expedite urbanization. Priority No. 2: The flood plain area of the South Platte River from the mouth of the Cache La Poudre where it converges with the South Platte up through the mouth of the Big Thompson or the convergence point on the South Platte. The City of Greeley and adjacent communities through its new water grid system is tending to follow development in areas adjacent to this flood plain. Priority No. 3: The flood plain area of the South Platte River from the convergence of the Big Thompson River to the Adams -Weld County line. This area is experiencing urban development along many points. Mr. '.;tan Miller Greeley -Weld C 'nty Flood Flair, Study Page 3 There is a main rail system and four -lane highway system parallel to much of the river zone. Public Service Company of Colorado is currently developing a large nuclear power plant in this area near Platteville, Colorado. This should increase the urbanization in this river plain area. The area surrounding Fort Lupton, Colorado, is noting a definite urbanization increase. rriority No. 4: The flood plain area of the I-oudre River above Sheep Jraw to the Larimer County Line and the South Platte River from its convergence with the Cache La Poudre river east to the Weld - Morgan County line. Much of this area follows the main transmission water system of the City of Greeley and future development will be aided by this. Much of the future planning of this flood plain would have an indirect effect on the area in Priority 1. In addition to the above facts, it must be noted that the City of Greeley and all towns and cities along the :south Platte Basin have shown a definite growth increase since 1950. Greeley's area now serves upwards to 40,000 persons which is a growth of some 10,000 in the past twelve years. At the same time, Fort Lupton, Platteville, and others have felt the impact of the U.S. 85 four -lane highway developed in the past ten years. Mr. Stan Miller Greeley -Weld C my Flood 'Plain Study Page 4 Other growth items are the contract to build the new Public Service nuclear plant near Platteville which will attract large numbexsof construction people to live along the complete river basin. The plat will be built in the river valley fringe area. Colorado State College in Greeley has a high rate of growth and the projection of students into the 1980's shows a doubling of staff and students. Industrial development is continuing north from Denver into all these priority areas. The study is urged to provided a basis for zoning these flood plain areas to protect them from the growth and continued expansion of the Greeley region.

To provide information for the determination of any desirable flood damage protection measures. 4. To provide information relative to future flood back- water conditions which have a bearing on the internal drainage problems of Creeley and other affected communities. SCOPE AND SUGGESTED PROCEDURES A preliminary flood plain report should be prepared that would include profiles for each river. This information, in part, could be obtained by the cooperating community areas or governmental agencies under the direction of the reporting agency. The limits of areas inundated by selected flood under given conditions should be shown on suitable topographic maps. Also, any information that might be useful for future flood protection planning. It is recommended the study be completed by January 1, 1968. AVAILA3ILITY OF DATA 1.
