<br />PREFACE
<br />
<br />quantity takeoffs from tho preliminary design,and unit costs
<br />were based on current prices. NO attempt W<l5 made to inflate
<br />prices to a future construction date.
<br />
<br />This study presents floodplain information and rf'commended
<br />drainage improvements for a drainage basin located in north-
<br />western Fort Collins designated the West Vine Drainage Basin.
<br />The study is intended to bQ a planning tool fOt" use by the
<br />City of Fot"t Collins to aid in planning for future development
<br />as it relates to the major drainageway plan. Hydrology used
<br />for the design of future drainage f<lcilities within the basin
<br />should be consistent with the hydrology contained in this report.
<br />Future drainage facilities should be compatible with and compli-
<br />ment the drainage improvements recommended herein.
<br />
<br />Copies of this report are available from the City of FOt"t
<br />Collins. A Technical Addendum to this report is also available
<br />for review at the City of Fort Collins; however, it is not
<br />available for public distribution. The Technical Addendum
<br />includ"s <'111 pertinent nata and calculations \lsen in the
<br />hydrologic and hydraulic analyses and the preliminary design
<br />of drainage facilities.
<br />
<br />This study was authorized by the City of Fort Collins in
<br />coopcration with the Colorado Water conservation Board. The
<br />study was completed by Eng.ineering Professionals, Inc. of Fort
<br />Collins, Colorado, under an agreement dated June, 1981.

<br />The West vine ~ajor Drainageway Study, as m~ntioned previously,
<br />is a [:llanning tool to aid in determining present and future
<br />drainage facility needs.As such, the Eloodolain was dcli~eated
<br />to aid in determining benefits from alternative drainaqe
<br />tac~l~ty constructiol'.. 'fhe floodplains ,;hown on FiYlln,," G
<br />through 10 were derived assuming future, full development
<br />hyd~ology with existing drainage faciliti~s, and existing
<br />development hydroloqy, the extent of development being determinect
<br />from June to NQven~er of 1980, with existing drai~aqe facilities.
<br />Major drainaye facility lmrrovement~ will alter the flOOdplain.
<br />Therefore, the City of Fort Collins should be contacten prior
<br />to using the floodplain data to determine it's applicability
<br />for any given situation.
