LTD. <br />MEMORANDUM <br />November 25, ZQ09 <br />TU: <br />FROM: <br />RE: <br />HRS Water Consuftants, inc. <br />c/o Peter Boddie <br />Ron McLaugh(in <br />Swan's Ne:t Metropolitan District Storage Tank <br />��`����/ <br />�� ��� <br />� o� <br />You asked that we provide a{range-level} valuation far the District's existing water starage tank. <br />It is understood that this vaiue is based on oNy furnished information, without out field <br />inspeabon, and should be r�arded on�y as an approxima#ion. <br />Basic l�ormatlon <br />d. Tank is constructed of rein#a cancrefe, of square shape approximately 42 ft. X 42 ft. X <br />14 ft. height. Most of the tank is above grade. <br />�► Maximum storage volume is 133,�00 galfons. <br />af. Use 1980 as most probable construc#ion date. <br />�i. Present tank condition as describ�l by Llquid Engineering Corporation Condition Surveys <br />dated Septemlaer 3, 2008 {T. Spu�ling} and by three furr�ished photos o# exterior walis. <br />� Tank constructed in mauntain area near Breckenridge, in Summit Caunty. <br />Discussion <br />This is an unusua! tank for a mountainous area. Cancrete tanks, especially rectangular, can be <br />severely damaged if sign�cant interiar ice forms. Since this tank is abaut 30 years old, and in <br />better-than-expec#ed condition, �t is probable that this tank experien�s fairly rapid tumover <br />(thus minimizir�g freezing) in the win#er. Same cracks are visible in the photos, and the report <br />Indica#es some surface damage {probably from freeze-thaw cycles). <br />VaEuation <br />Use Replacement Cost New less Depreciation {RCNLD} appraach. <br />Fram our expe�ience, an average 2009 unit cast #or reinforced concrete storage tanks, in this <br />slze range, would be approximately $2.25/galion. Below gracie (or insulated) #his tank shauld <br />have as useful life of over 140 years. Exposed, as is, a reasonable es#imate o# useable life is <br />about 50 years (see Rec,�mmendat�on foqowing). <br />P 1PROJECTSIHRS OT-18W7-18-03 Swans Nest1RCM MemO to PBoddie re 51ot8ge Tank.dOC <br />
