GUEST: DANIEL OWNERS -1211 E. BATES PKWY. -SEWER LINE VARIANCE TO BUILD A GARAGE. Mr. Daniel Owens of 1211 E. Bates Parkway appeared to request the Board grant an exception to the Municipal Code 12-3-K which requires him to replace the existing sewer service line under his new proposed garage. Mr. Owens noted that he picked up the information and requirements for building a new garage in December 2001. The ordinance requiring him to replace his line was passed in January 2002 and he was unaware of the new ordinance until his contractor told him of the additional expense. He explained the hardship that would be created by having to replace the sewer service line. Mr. Fonda reviewed the original reasons for passing the ordinance. The only section of line that would have to be replaced would be the section going under the garage. The Board recommended allowing an exception and with instructions to the City Attorney to draft an agreement that would be recorded against Mr. Owen's property stating that an exception was granted and the sewer line under the garage does not meet code. Mr. Kasson moved; Mr. Otis seconded: Ayes: Nays: Members absent: Motion carried. The board agreed to grant an exception to Municipal Code 12-2-4-K: New Construction Over Existing Sewer Service Lines to Mr. Daniel Owen, owner of 1211 E. Bates Parkway, on the condition that an agreement drafted by the City Attorney be recorded against the property. Woloysn, Clark, Bradshaw, Cassidy, Otis, Kasson, Habenicht, Moore None Higday NOTE: The City Attorney deemed that the Board of Adjustment and Appeals would be the official entity to grant a code variance. Mr. Owen was notified to direct his appeal to the Community Development Department. 3. CITY DITCH AUGMENTATION PLAN. The Board received a copy of the Application for Approval of Plan for Augmentation for the City Ditch that has been filed in District Court by David Hill, Englewood's Water Attorney. 4. FLUSHERJV ACUUM TRUCK. The Utilities Department staff has requested a combination flushing/vacuum truck that will allow the crew to remove blockages at the first point of contact rather than having to . flush the debris to the nearest trunk line. The proposed truck will allow removal of the blocking solids at the point of the problem instead of progressing through the entire system to the treatment plant. The cost is expected to be approximately $200,000. The board is being asked to recommend the purchase to Council before final bids are received due to the hazardous nature of the existing flusher truck. Mr. Habenicht moved; Mr. Cassidy seconded: Ayes: Nays: Members absent: Motion carried. To recommend Council approval of purchase of a sewer line flusher/vacuum truck (vactor truck). Wolosyn, Clark, Cassidy, Otis, Kasson, Habenicht, Moore, Bradshaw None Higday 5. WATER TASTE & ODOR CONCERNS. The Board received a memo dated May 1, 2002 from Stu Fonda to Englewood City Council regarding recent taste and odors in Englewood's drinking water. Due to current drought conditions there are little or no flows being released from Chatfield Reservoir. The slow flow rate, combined with the sunlight and nutrients present, are causing algal blooms in the river. Algae produces oils which can pass through the treatment plant process. These oils, even in low quantities, produce objectionable taste and odors. In an effort to improve the taste of the water, the Allen Filter Plant will be increasing diversions down the City Ditch and introducing powdered-activated carbon. The Utilities Department will be considering whether long-term powdered activated carbon facilities should be added to the treatment process. 6. HOLIDAY PARADE. The Board received a memo from Council member Olga Wolosyn regarding the 2003 Englewood Holiday Parade . Various boards and commissions are being encouraged to sponsor a float, volunteer to work the parade or apply to serve on the parade committee. 7. RATE INCREASES . Stu notified the Board that water and sewer rate increases are being discussed. The Bi- City Supervisory Committee is reviewing pending regulations that will be affecting future rates. Rate increases will be discussed at future Council study sessions and a joint meeting with the Littleton City Council. 8. CENTENNIAL AGREEMENT. Negotiations are nearing completion for the Centennial water agreement and should be ready for Water Board review by early fall. Stu noted that voluntary watering restrictions are now in place. The meeting adjourned at 5:55 p.m. The next Water and Sewer Board meeting will be Tuesday, June 11, 2002 in the Community Development Conference Room.

FRASSETTO , Esa. OF COUNSEL EVE HOLLENBECK.CPA ACCOUNTING SERVICES South Platte River/College View/Overland Areas My of'i ce has been asked by Mr. Bill Miller of 2319 West Harvard Ave ., Englewood , Colorado 80110 , and others , to inquire into what appears to be a considerable gnat problem in the area between Federal Boulevard and Santa Fe Drive in the commercial and residential areas near the Platte River and the Excel power plant in Englewood , Colorado . After inspecting the area , and after talking to residents and bus iness owners in the area , it appears that there has been a considerable increase in recent years of the number of gnats in the area causing residents and business owners to consistently suffer from gnat bites . Some have even gone to their physicians to receive special mediation to combat the discomfort and effects of the bites. It appears to me that the increase in the number of gnats is a result of numerous areas of standing water from streams which eventually flow into the South Platte River. Having seen the gnats myself, and after talk ing to some of the people in the area , the situation appears to be a public nuisance. It is my understanding that the State Health Department and City of Englewood have investi gated this matter at the request of Mr. Miller , but have decided to not to do anything . I would appreciate it if you could write to me and let me know what investigation was done and whether a state or private entomologist was consulted to investigate the cause of the gnat problem , whether the number of gnats in the area is typical, and if not typical , what could be done to reduce wha! :nar.y bel ieve is a public health !hreat. Your consideration and attention is appreciated and I look forward to hearing from you in the not too distant future .

M r. Miller contends that the insects are adversely affecting his quality of life and that the source of these insects is West Harvard Gulch. Together, we toured West Harvard Gulch from the S. Platte River to Federal Boulevard. We were unable to locate any signs of raw sewerage being discharged into the gulch but did observe several areas of slow moving stagnant water due to the low flow in the gulch . The slow moving water is excellent breeding grounds for insects. These areas both upstream and downstream of Mr. Miller 's property are in unimproved sections of the gulch located in the City of Denver. The City of Denver has plans for a bike trail along this section of the gulch but these improvements include only minimal channel improvements. In the City of Englewood , West Harvard Gulch runs through the Northwest Greenbelt where the gulch has been improved with a lined low flow channel. Finally, I spoke with Mr. Jody Erwin of Tri-County Health and Mr. Dale Condra of State Health Department. Both have investigated Mr. Miller's claim. They found no evidence of raw sewerage being discharged and the insects to be a nuisance species , not a public health threat. Therefore they took no action . At this time, I recommend that Mr. Miller either spray his property or purchase an electric insect sapper. A-rr. 3 DRAFT HOTEL SEWER TAP AGREEMENT THIS AGREEMENT, is made the __ day of , 2002, between the CITY OF ENGLEWOOD whose address is 1000 Englewood Parkway, Englewood, Colorado 80110, (hereinafter City); and the DEN MAR LLC an Indiana Limited Liability Company, whose address is 1000 E. 80th Place, Suite 600N, Merrillville, IN 46410, (hereinafter Den Mar). WHEREAS, Den Mar requested a reduction in sewer tap fees because they believe their Hotel's water usage is l ess per unit than a single-family equivalent. The subject Hotel is located 10325 Park Meadows Drive, Littleton, Colorado, also known as Parkridge Marrida WHEREAS , the standard tap fee is based on a normal flow of two hundred (200) gallons per day and Den Mar estimates that their per unit flow is no more than one hundred (100) gallons per day. NOW THEREFORE the Parties agree as follows: 1. The City will sell 278 sewer taps for its Hotel units at one half the standard sewer charge , based on their estimate of no more than 100 gallons per day per occupied unit real flow . This is a minimum charge and in no event will the base tap fee be less than one-half (1/2) the standard sewer charge. 2. The initial tap payment to the City by Den Mar will be $194,600, for Englewood tap fees ; $12.50 for the permit, and a Big Dry Creek Interceptor Basin Charge of $13 ,900 .00 , for a total of $208 ,512.50 . 3. Den Mar will issue an irrevocable, stand-by letter of credit in the amount of $208 ,500 .00 , which will be used for any additional tap fees. This letter of credit will be held by the City for tap fees as required pursuant to this Agreement. 4. The City will monitor winter (November 1 through April 30), bi-monthly water usage at the Hotel during a five (5) year period . During that time, Den Mar will monitor water consumption on a daily basis. Den Mar will furnish the City with a report on daily water consumption and the number of rooms occupied on the corresponding days. They will submit the report to the City on a monthly basis. 5. If at any time during the five (5) year period, the daily, per unit consumption goes over one-hundred (100) gallons per day, Den Mar will pay the additional tap fee owed. If the fee is not paid within sixty (60) days, the City will make periodic draws on Den Mar letter of credit to pay to the City additional sewer tap fees based on the amount of flow in excess of one hundred (100) gallons per day as billed by the City of Englewood. If Den Mar's daily, per unit usage is less than one hundred (100) gallons per day, the City will not owe Den Mar any refund. 6. Additional sewer tap fees will be computed on the basis of two hundred (2 00) gallons per day being equal to a tap fee of $1,500.00. As an example , if the usage goes over one hundred (100) gallons per day by five (5) gallons per day , then five (5) gallons per day is two and one-half percent (2 112%) of the two hundred (200) gallons per day, two and one-half percent (2 112%) ofone thousand five hundred dollars ($1,5 00) is thirty- seven dollars and fifty cents ($37.50) times one hundred and sixty-one (161) hotel units is six thousand thirty-seven dollars and fifty cents ($6,037.50) in additional sewer tap fees. The higher amount, in this example the 105 gallons per day per unit, will become the new base line for tap fees. Once the baseline reaches 200 gallons per day, per residential unit, the maximum tap fee will be owed. In no event shall the total tap fees exceed one maximum tap fee per unit. 7. However, should additional units be added to the project at any time , the tap fees shall be increased by the number of additional units. If the units are added after the five (5) year period described in paragraph 5 above , or after a final base line for tap fees has been reached, the tap fees for the new units will be the same as the final tap fees for the original units. 8 . Any accidental discharge of metered water of an unusual and non-recurring nature where the City is notified within 24 hours of discharge and Den Mar provides documentation of t he nature and extent of the discharge may be excluded from the calculation of the tap fees. The filling of a swimming pool will not be considered an accidental discharge under this paragraph. 9. At the end of five (5) years or on the date on which Den Mar has paid the additional sewer tap fees associated with an increase in the baseline for tap fees to 200 gallons per day per unit, whichever event shall occur first, the letter of credit may be withdrawn and the City will no longer monitor water usage except for normal, annual sewer billing purposes. 10 . Any. additional tap fees paid pursuant to this agreement are tap fees only and shall not be considered sewer treatment char ges. Any money owed the City under this Agreement is a fee for the sewer tap. 11. The City and/or its auditor maintains the right to enter the property to examine the water use records , the hotel occupancy records and to check water meter readings. 12. Den Mar gives the City the right to disconnect the hotel for nonpayment of any tap fees or sewer treatment fees due the City. 13. This Agreement shall not be assigned by any party without the prior written consent of the other and this agreement shall be binding on any successors or assignees. 14. Den Mar confirms it has 278 units in this Hotel and agrees that it shall not add additional hotel units to the City of Englewood's sewer system without written approval of the City. 2 15. Any notice required or permitted by this Agreement shall be in writing, and shall be deemed to have been sufficiently given for all purposes if sent by certified mail or registered mail, postage and fees prepaid, addressed to the party to w horn such notice is to be given at the address set forth below, or at such other address as has been previously furnished in writing, to the other party or parties.

In response to your request, I have prepared the following work scope that outlines the process THK will follow to establish the current and anticipated value of the seven to ten-acre proposed Transit Station/Village property and adjoining nine acres of parking, which is part of the City of Englewood's holdings in the Highlands Ranch Business Park. Specifically, the site is located at the southwest corner of C-470 and Lucent Boulevard. We understand that this preliminary value estimate will be used to formulate a strategy for negotiating a lease of the property to the RTD. In order to formulate this value estimate, THK will prepare a current and anticipated value for the site. Current Value Regarding the current value of the property, THK will research recent land sales and land leases in the Highlands Ranch Business Park vicinity. This data will include: • • • • • • • Size and location Sale or lease terms Zoning Terms Grantor and grantee (lessor/lessee) Availability of utilities Other important parcel characteristics Using this data. THK will estimate the current value of the subject property. Value as a Transit Station Knowing that the parcel will be used for a transit station/village, THK will also research the sale or lease of property for other transit stations/villages in the metro area. For these properties, we will obtain the same information as described above. A review of this data will allow us to determine if the use of the property as a light rail transit station/village is in-line with a more traditional land use. 2953 South Peoria Street.

S Memorandum cc: Stu Fonda Joe Pershin From: Joe Tom Wood , P .E. Date: May 6, 2002 Subject: Water Supply Outlook for Englewood I. 2002 Water Supply Outlook for En~lewoo<i A. Introduction Englewood owns several very senior water rights which divert from the South Platte River at Union A venue. While these water rights provide the City with an ample supply of water, in dry years, such as the summer of 2002 appears to be , the low streamflow in the river, to~ether with the demands for water from other senior riihts, may result in the City's senior river ri&hts not being able to provide the City with all of the water needed. In order to answer the question of whether the City's senior river rights will be able to supp ly the C1tis needs · during the year 2002, the followini analysis was performed. B. Analysis 1. River Streamflows Historical river streamflows for the year 1954 were taken to represent streamflows of the year 2002. The year 1954 is generally regarded as the driest year with the lowest streamflows of record for the South Platte River . Whether strcamfl.ows in the year 2002 will actually fall as low as those historically recorded in the year 1954 is anyone's &uess, but the 1954 streamtlows were used to test the ability of Englewood 's senior river rights to satisfy the City's year 2002 water requirements . 1 2002 05/06 KON 15:44 FAI 3035262624 MARTIN AND WOOD WATER 444 Englewood Utilities Ill 003 /010 2. Englewood Wat.er Requirements En~lewood's daily water requirements for the year 2002 were taken to be the daily water requirements historically observed for the year 2001, but with the City's year 2001 daily irrigation water requirement increased by 15 % to represent the hot and dry conditions which may oceur in 2002. For reference, the City's total raw water requirement in 2001 was 9,600 acre-feet, with a maximum daily requirement of 32.4 cfs. The projected 2002 total raw water ICqUirement for this analysis is 10, 100 acre-feet, with a maximum daily requirement of 36.1 cfs, 3. Ana1ysis of Adequacy of En&lewood's Senior Wa~r Rights The analysis then compares, on a daily basis, the total availability of Englewood's senior river rights, together with the City's senior McBroom Ditch right, with the City's 2002 daily water requirement. All of the City 's changed Nevada Ditch, Brown Ditch, and McBroom Ditch rights are used in the "single-use" mode, because this mode maximizes the water availability for the City's domestic use. The analysis calculates on a daily basis any shorta&c in the City's supply, and these short.ages are summed into the monthly shortaees depicted in Table 1. Column 1 of Table 1 indicates that En,lewood' s senior rights will begin to fail to supply the City with its domestic water requirement in the month of June, and that shortages will continue throu&h the month of November, totiling some 343 acre-feet for the year. Column 2 represents the reduced shortages which may be expected as a result of Englewood's invocation of a relatively recent a2feement with Denver Water . This agreement provides that Denver will provide water to Englewood to compensate the City for short.tges in her senior river rights which are attnoutable, in part, to evaporation from Denver's Eleven-Mile Reservoir in South Park. The agreement limits Denver's provision of water to Englewood to no more than 750 acre-feet in any year. 4. Solutions to Englewood's Shortages Englewood has three means by which to eliminate shortages in her supply for the year 2002. These include (a) drawing water from Mclellan Reservoir~ (b) utilizing the Bear Creek augmentation plan which requires a lesser amount of water from McLellan Reservoir; and (c) diverting reusable wastewater return flows from the river. 2 20~2 OG /06 KON 1G:4G FAX 3033262624 MARTIN AND WOOD WATER ~~~ Englewood Ut111t1e& Ill 004 /010 a. McLellan Reservoir To eliminate shortages from the City's senior water rights, the City may simply withdraw water from McLellan Reservoir and run it down City Ditch for delivery to the City's Allen Filter Plant. b. Bear Creek Augmentation Plan The City some years ago obtained a decree from the W~r Coun approving the City's right to divert from Bear Creek at the McBroom Ditch and to augment such diversions when the diversion are out-of-priority. At this time, it appears that augmentation of such diversions will be required for the remainder of year 2002 because of senior calls on the river. The City has also constructed a pipe from the McBroom Ditch diversion from Bear Creek all the way to the City 1 s river reservoir located along the river at Union Avenue. Thus, the City now has the physical means by which to deliver Bear Creek water to the Allen Filter Plant. When the City uses her Bear Creek augmentation plan, she must place water in the river in the amount of that pa.rt of the diversion which does not return to the river. In the summer, due to much use of water for irrigation, the amount which the City must place in the river -i.e., the augmentation amount - may equal two-thirds of the diversion. Thus, if the City were to divert 3 cfs from her Bear Creek rights, she would have to place 2 cfs in the river. For the year 2002, the City would likely take this 2 cfs from McLellan Reservoir and place it in the river. Using the above example, if the City needed 3 cfs, the City could either (1) rake 3 cfs directly from Mclellan Reservoir, or (2) the City could take 3 cfs from Bear Creek, ind take 2 cfs from McLellan Reservoir and place the 2 cfs in the river. Thus, the augmentation plan allows the City to use the same amount (3 cfs) for her domestic needs, while reducing the amount of water needed from McLellan Reservoir. 3 2~02 05 1 06 ION 15:43 FAX 3033262624 HARTIN AND WOOD WATER~~~ Englewood Utilities ~005 /010 c. Diversion of Reusable Return Flows Both the City of Englewood and Centennial Water and Sanitation District own and use reusable water . When reusable water is used, the return flows (treated wast.ewat.er and irrigation rerum flows) may again be diverted and used. Much of Centennial' s water supply derives from .reusable sources which result in reusable return flows accruing to the river upstream from Union Avenue. Cent.ennial's decreed augmentation plan allows for the quantification of such reusable return flows and for Englewood to divert like amounts at Union Avenue . To the ext.ents (1) that Cent.ennial ha& reusable return flows which are surplus to Ccntcnnial's augmentation plan and (2) that Centennial grants Englewood pennission to divert its reusable rerurn flows, this source of water may help to eliminate shortages in En&lewood' s year 2002 water supply . While the diversion of such reusable return flows may prove helpful in eliminating shortages, such opportunities for En&lewood to divert this source may occur during periods of very low river flow with attendant poor water quality . If any agreement is made between Centennial and Englewood regarding Englewood's diversion of Centennial' s reusable retum flows , Englewood should have the option to elect in her sole discretion whether to divert such water. II. En&Iewood's Provision of Water to Centennial in Year 2002 A. Current Water Supply Agreement En&lewood has for several years been providin~ water to Centennial under a temporary agreement . This agreement provides that Englewood will supply Centennial with 1 1500 acre-feet per year on a designated monthly schedule, and that Centennial will pay Englewood for such wat.er at a relatively high price . The agreement also provides that Englewood will supply Centennial with if-and-when water beyond the scheduled 1,500 acre-feet, and that if Centennial. elects to purchase such if-and-when water, Centennial will pay Englewood for such water at a relatively low price . For several years Englewood has provided Centennial with the 1,500 acre- feet of high priced scheduled water and also with varying amounts of lower- priced water . 4 200% 03/08 ION 13:43 FA.I 303~262624 HARTIN AND WOOD WATER 444 Englewood Utilities ~008 /010 B. Year 2002 Outlook for Englewood Supply to Centennial Table 2 swmnarizes the likely sources of Englewood's proVlSl.on to Centennial of the 1,500 acre-feet of scheduled water. Englewood is expected to provide 1,535 acre-feet to Centennial in the year 2002. To date, Englewood has supplied Centennial with approximately 300 ac.rc- feet. Englewood will receive from Denver Wat.er her 40 % of the Ranch Creek Basic Delivery which amounts to 520 acre-feet. Englewood will receive no Ranch Creek Paid Delivery water from Denver Water in 2002. Englewood's agreement with Thornton and Westminster will provide at least 75 acre-feet. The agreement provides fo.r a delivery to Englewood of between 75 and 450 acre-feet, so the delivery may be more than 75 acr~feet, although with this dry year, only 75 acre-feet can be counted upon. Englewood's Boreas Pass Ditch is expected to provide approximately 100 acre-feet. Englewood's LF-M2 Well is a deep Denver Basin aquifer well located above Mclellan Reservoir. Because of the banking provisions in its Water Court decree , this well has some 1,000 acre-feet banked for furure use. The well pumps at a rate of approximately l cfs, or 2 acre-feet per day, or 60 acre- feet per month. This well is pumping continuously now, and for the last eight months of the year (May -December), it is expected to produce approximately 480 acre-feet. Englewood's interests in the Guiraud and Demmick Ditches are expected to produce approximately 60 acre-feet It is import.ant to note in the contexts of Englewood's year 2002 shortqe and Englewood's ability to provide Centennial with 1,500 acre-feet of high-priced sclleduled water, that Englewood currently hti 2,100 acre- feet of water stored in Mcl.ellan Reservoir. ill. Outlook for Next Year-Year 2003 A. Englewood Water Supply If a drought like that of 1954 were to continue through the year 2003, one would expect that En&lewood 1 s senior rights would minimally fall short of 5 2002 05 /06 ION 15 :45 FAX 3035262624 MARTIN AND WOOD WATER ~~~ Englewood Utilities ljl!007 /010 satisfying the City's domestic needs to about the same extent as shown in Table 1. Again the City's solutions would probably be to use the Bear Creek augmentation plan and/or water from Mclellan Reservoir. B. Englewood provision of Water to Centennial One would expect the pendin& water and facilities lease with Centennial to be initiated by the beginning of the year 2003. Like the temporary a&reement with Centennial, the pending lease also provides for Englewood to deliver to Centenni.a.1 1 ,500 acre-feet of relatively high·priced water. Table 2 can fairly be used to depict the sources of water which Englewood is expected to have for delivery to Centennial, with few changes. Englewood's 40 % of Ranch Creek Basin Delivery water will remain at 520 acre-feet. Per agreement with Denver Water, it may be larger than 520 acre- fcet, but i t can 't be smaller. The Standley Lake, Boreas Pass , and Guiraud/Demmiclc sources are expected to remain the same, and one should disregard year 2002' s 300 acre- feet delivered to date . After the year 2003 the banked water available to the LF-M2 well would be exhausted, or nearly exhausted, and it would thereafter be limited to approximately 127 acre-feet per year . For this and other reasons , Enilewood should consider the construction of at lease one additional deep Denver Basin aquifer well. Englewood has some 3 ,000 acre-feet per year decreed to such wells, and because the decrees were entered ten years ago , Englewood has some 30,000 acre-feet banked and available for drought use, if a well(s) is constructed and ready for use. The sum of the sources for year 2003 is 1,475 ac1e-feet. The minor difference of 25 acre.feet from the 1,500 acrc·fcct delivery figure could come from Englewood 's water in McLellan Reservoir. IV. Englewood's Water Quality When the river flow at Union Avenue is low, the river's water quality frequently is poor, and in turn Englewood's treated water frequently is subject to taste and odors. The amount of water released to the river from Chatfield Reservoir eenerally governs the amount of river flow at Union Avenue. In past years very little flow has been released to the river in the winter. Typically, in January or February, Chatfield Reservoir has filled, and increased releases to the river then occur, and water quality improves. During other times of the year, releases from Chatfield 6 2~02 08 /06 MON 15 :46 FAI 3035262624 MARTIN AND WOOD WATER ~~~ Englewood Utilities ~008 /010 Reservoir have generally been large enough so that En1Iewood has not suffered water quality problems. Recently Englewood has suffered taste and odor in her drinking water, because releases from Chatfield reservoir to the river have been very low. For the following reasons Englewood is expected to suffer poor raw water quality more in the future than in the past. Denver Water owns water storaee riehts in Chatfield Reservoir. Pursuant to Federal requirements, Denver is obligated to maintain a flow in the river between its Strontia Springs Reservoir and Chatfield Reservoir of 30 cfs in the winter, and 60 cfs in the summer. Frequently, these flows would not naturally be in the river, so Denver releases water from its upstream reservoir (Cheeseman, 11-Mile, Antero, and Strontia Springs) and supplements the fl.ow in the Strontia Springs-to-Chatfield reach to maintain the required 30 or 60 cfs flows. Denver then recaptures these storage releases in Chatfield Reservoir . While Denver is recapmring these storage releases in Chatfield Reservoir, and otherwise storing water in Chatfield Reservoir, frequently there is little water released from Chatfield Reservoir to the river, sometimes causing water quality prob1cms for En21ewood. But , this recapture can't go on forever. Chatfield slowly fills up, and then it begins to spin Denver's waier into the river. This has typically occurred in January and February . For years Denver has been considering a physical hookup between Chatfield Reservoir and its Conduit 20 which runs to Denver's Marston Water Treatment Plant. Conduit 20 runs a little west of Chatfield Reservoir and this plan would require both passage of water through Chatfield Dam and then a pump station a pipe line to Conduit 20 . Denver has ownership interests in Nevada Ditch and Last Chance Ditch and presumably would use these ownership interests to convey its water through the dam . Then Denver would need to build the pump station and pipeline to get water to Conduit 20 . Once Denver puts this .Plan into effect, it would be able to re-recapture the storage releases which it must provide to maintain the river flow of 30 or 60 cfs down to Chatfield Reservoir. To the extent that Denver is able to re-recapture these storage releases and run them to the Marston Plant for treaanent, the fillin2 of Chatfield Reservoir will take longer, and the result will be a more prolonged period of little or no release of water from Chatfield Reservoir to the river. Thus, Englewood should expect mare prolonged periods of poor water quality in the river at Union Avenue . 7 2~02 03106 MON 13:46 FAX 3033262624 MARTIN AND WOOD WATER ~~~ Englewood Utilities 51612002. 159.l 02 l!W/Martin aod Wood Wa= Comulcanu, lnc.
