Aerial Mapping Project TOWN of ESTES PARK Inter-Office Memorandum May 18,1999 TO: Public Works Committee FROM: Bill Linnane_4220 SUBJEcr: CBT Water Rights Purchase Background: Due to the high rate of growth in the Front Range, CBT water rights units are being purchased almost as fast as they hit the marketplace. Several water brokers in the area have informed me that the supply and demand of CBT units has caused the market value to increase from approximately $2,000 per unit in 1997 and 1998, to the current value of $4,000 per unit Additional discussions with personnel at the Northern Colorado Water Conservancy District (NCWCD) and with the River Commissioner indicate that unless the building industry in the Front Range does not taper off drastically, the CBT market value may not decrease in the near future. Town Attorney Greg White and I feel it is necessary that the Town take a proactive approach to CBT water rights purchases. (See the attached letter from the town attorney.) The Town's current supply of water rights is projected to be adequate through the next 10 to 15 years, but in the long term, the Town should increase its water rights supply. Since the CBT market value is not expected to decrease soon, it is a smart investment for the Town to purchase CBT units as they become available. (Continued on page 2.) Budget/Cost 1998 Budget $50,000 Cost $11,850 Recommendation: Retroactive approval of the $11,850 CBT units purchase is recommended. Background: (Continued from page 1) Greg White recently recommended the purchase of three CBT units at a cost of $3,950 per unit and a total cost of $11,850. Since it was necessary to react immediately, the Town purchased the three units. This PWC meeting action item is a request for retroactive approval. BL/lb Attachment GREGORY A.

Efficiently delivering water to its customers is a priority for the Town. The Town measures the efficiency of its water system by determining how much ofits production usage is accountable. It is difficult to determine an industry standard for accountable water. Any single standard (expressed in terms of volume or a percentage) for accountable water will not be valid, realistic, or appropiiate for many water systems. Many system characteristics - such as size, age, service population density, physical terrain, soil characteristics, and pipe materials - will affect leakage rates. The Town retained Black & Veatch to review its water accounting procedures and examine current programs and recommend additional strategies for increasing accountable water. This report documents the water accountability study performed by Black & Veatch. Study Findings Key findings and recommendations ofthe study are summarized below: . As shown by the following graph, accountable usage has ranged from 74 percent to 85 percent oftotal water produced during the past six years. Accountable Water Usage as a Percent of Total Water Production 90% 8596 11. 1, ,~>10, 80% 75% i -1.-I,Il. 700/0. : : 65% 1993 1994 1995 1996 1997 1998 Estes Park, Colorado May 1999 58697.100 1 Water Accountability Study . The water distribution system has about 40 miles of unlined steel pipe that is particularly susceptible to corrosion. The Town is prioritizing replacement of unlined steel pipe with ductile iron pipe in its annual capital improvement budget. At the current rate this replacement program will be completed in 25 years. It is recommended the Town accelerate the unlined steel main replacement program by leveraging annual cash outlays to finance this program through low-interest loans. . A planned meter replacement program should be implemented to replace meters at least every ten years. This will increase the efficiency of the metering system and maximize water sales revenue. • The radio-read metering retrofit program should be accelerated. This will lessen the Town's dependency on unreliable remote-read devices. . Increasing the amount of compensated usage through improved meter accuracy will increase annual water sales revenue. A one percent improvement in meter accuracy is estimated to produce an additional $ 10,000 in annual water sales. . A database of all meters in senice should be created using the recently acquired meter inventory program. Water System The Town' s water system consists of two treatment plants, a distribution system and water meters. Source of Supply The Town derives its water supply from two sources, Glacier Creek and Colorado-Big Thompson (CBT) project. Glacier Creek supplies the Gacier Creek treatment plant and CBT water supplies the Mary's Lake treatment plant. Treatment Plants Glacier Creek water treatment plant has a capacity of 3.0 million gallons per day. The plant's water production is measured by the meter located on the plant effluent line. This meter has not been calibrated since its installation in 1994. Estes Park, Colorado May 1999 58697.100 2 Water Accountability Study Mary's Lake water treatment plant has a capacity of 2.0 million gallons per day. A meter measures the water entering the plant and is calibrated annually by Northern Colorado Water Conservancy District and Town staff. Water produced by the plant is calculated as the metered influent less metered sewer discharge. Distribution System The Town gravity feeds treated water to its distribution system through three pressure zones. Average water pressure is 175 pounds per square inch (psi). Customers purchase pressure- reducing valves (PRVs) to lower water pressure to 40 to 70 psi prior to entering a residence or business. The Town has over 105 miles of water mains including cast iron, ductile iron, copper, and unlined steel pipe. The distribution system includes seven reservoirs with total storage capacity of 3.35 million gallons. Meters Water meters were first installed in the Town in 1976. All meters are located inside the customer's premise with a remote readout on the outside. The Town has approximately 3,700 meters in-service. Water Usage The water produced by the Town's treatment plants and distributed to the Town's distribution system is classified into three types of usage: compensated, uncompensated and unaccounted-for usage. Compensated Usage Compensated usage is revenue producing and includes water that is metered and sold to consumers. This would include water billed to utility customers by the Town's utility billing staff, bleeders that are metered and billed, water sold at water dispenser, and bulk water sales. Historical compensated usage for the past six years is summarized below.

Estes Park, Colorado May 1999 58697.100 4 Water Accountability Study Unaccounted-For Usage Unaccounted-for usage is water produced and distributed to the system that is not accounted for in compensated or uncompensated usage. This usage includes unknown leakage, inaccurate meters, and other unknown losses. Historical unaccounted-for usage for the past six years is summarized below.

(d) Based on 11 months. Potential Sources of Unaccounted-For Usage An accurate system of water accounting is very dependent on an accurate system of metering. Water systems should meter at the source, at key points in the distribution system, and at customer premises. This section discusses actions the Town can take to minimize its unaccounted-for water usage. Water Production Metering Water produced at the Glacier Creek water treatment plant is calculated by the meter located on the plant effluent line between the plant and the reservoir. The Town has recently installed a meter on the influent line to the plant. The effluent meter has not been calibrated since its installation in 1994. 11 is recommended that all plant nielers be calibraled annually. Water produced at Mary's Lake plant is calculated as difference between metered influent and metered sewer discharge. Il is reconimended a meter be installed on plant's effluent line to measure plant produclion as well as m delermine plant losses. It is further recommended the Town Estes Park, Colorado May 1999 58697.100 5 Water Accountability Study continue its practice ofcalibratingthesemeters annually. Reservoir Seepage Based on industry standards, daily seepage from buried concrete reservoirs should not exceed 0.05 percent oftotal capacity, or about 500 gallons per day, from a one million gallon storage tank. It is recommended the Town consider metering its reservoirs to determine amount of seepage. Distribution System Losses Distribution losses occur through undetected leaks in deteriorated mains. The Town has about 40 miles of unlined steel pipe in its distribution system. In 1985, the Town discovered that their water was particularly corrosive to unlined steel. A rust inhibitor, zinc orthophosphate, was added to the water to slow corrosive effects and reduce incidence of "red" water. The Town is prioritizing replacement of unlined steel pipe with ductile iron pipe in its annual capital improvement budget. At the current rate this replacement program will be completed in 25 years. 11 is recommended the Town accelerate the unlined steel main replacement program. Tfus may require the Town to borrow low-interest loans and use the annual cash outlay for payment of debt service on these loans. Distribution system losses also occur through detected main breaks. From 1993 to 1997, the Town spent over 1600 staff-hours repairing 105 main breaks. Town policy is to repair lines when they are "live" which means that water is flowing during repair. It is recommended that the Town implement a formal leak detection program to ident* potential main breaks before they occur. Service line breaks are another source of distribution system water losses. From 1993 to 1997, the Town spent over 650 staff-hours repairing 220 service line breaks. Unfortunately, service line leaks are often undetected because the water meter is typically installed inside a customer's premise. Inaccurate Meters Water meters are located in the customer's premise with a remote reading device located outside. Meters were installed in 1976 and are generally replaced only when they are stuck and not recording any water usage. Slippage in meter readings occurs as meters age. Although Town bench tests conducted in 1998 indicate 98 percent accuracy, these tests may not precisely emulate field conditions and may mask inaccurate readings. 7-he American Water Works Association recommends utilities should have aplanned prograni to replace meters every ten years. This w\\\ Estes Park, Colorado May 1999 58697.100 6 Water Accountability Study allow the metering system to be efficient and to recover maximum revenue to the Town. The water usage recorded by the remote-read device is the basis for determining compensated usage. Although convenient to read, this device will often under record usage. Additionally, the wire between the device and meter is sometimes broken. 777e Town has recently initiated a program to replace remote-read devices with radio-read devices. It is recommended this program continue and be accelerated, if possible. The Town has recently purchased a program to record meter information such as serial number, date of installation, date and nature ofrepairs, size, and location. It is recommended the Town enter information into this program for every meter in its system. This w\11 facilitate the meter replacement program. Fiscal Impact Revenue lost from unaccounted-for water is related to understated compensated usage caused by meter inaccuracies. At the Town's existing water rate of $2.70 per thousand gallons, a one percent improvement in meter accuracy is estimated to produce an additional $10,000 in annual water sales.

RE: Town of Estes Park Solicitation of Professional Services Request for Proposal did 2/99 "Aerial Photography for Planimetric Database Acquisition" Dear Mr. Dekker: After lengthy deliberation over the last three days, AERO-METRIC has come to the decision that we have no choice but to respectfully file a formal complaint and objection to the selection process by the Town of Estes Park for the proposed contract for "Aerial Photography for Planimetric Database Acquisition". We have found that there is sufficient reason to believe that the Town acted improperly in accepting the proposal of Kucera West, Inc. In a question put to him directly, Mr. Shawn Kraft of the Public Works Department, responded to us that the proposal from Kucera was delivered to the Town "by some guy about 4.30 pm" the day of March 5, one half hour after the deadline of 4:00pm as stated in the Request for Proposals. In further comment, Mr. Kraft volunteered that he thought he had to accept the late proposal from Kucera because "the Committee would not like it if he presented them with only one proposal (AERO-METRIC's)." [AERO-METRIC's proposal was delivered in person by its Regional Manager and Vice President at 2:00pm, and at the time at which discussions were concluded with Mr. Shawn Kraft, about 3:30pm, no other proposals had been received.] Having previously been in similar situations, AERO-METRIC contends that the Town should neither have accepted, nor considered, the proposal submitted after the stated deadline, and that the Town erred in so doing, violating the professional proposal and selection process. Secondly, AERO-METRIC would challenge the selection process for this specific contract, of such a significant value and of such technical complexity, in that the Town did not request, nor allow for, a formal presentation and interview with the qualified proposers, as is customary in the selection of a professional consultant. AERO-METRIC has found in discussions with Mr. Kraft that he does not well understand the Q) Offices 1.,cited in Al.,41, 6,1.,rn.10, Fl.,rida, Minne,orn, Virginia, Washinen,n and \T'i<on,in. . Town of Estes Park April 26,1999 Page 2 technical aspects and subtle differences of the proposed services, which could make significant differences in the value of the proposed services to the Town. AERO-METRIC doubts that the Public Works Committee (Committee) could have made an informed decision in this case if relying solely on Mr. Kraft's understanding. We make a formal request for the opportunity to make a personal presentation to the Committee concerning the qualifications of AERO-METRIC and of the specific and unique benefits and merits of the services contained within our proposal. We would also challenge and invite the Committee to visit and inspect our facilities, and determine firsthand the capabilities of AERO-METRIC to provide the best possible service and value to the Town in this significant contract effort for detailed mapping services, which the Town has not had done for approximately 20 years, and which must serve the Town for many more in the future. AERO-METRIC requests that this letter be transmitted to the Town Board. We await your prompt response in this matter, and stand ready to answer and serve the Town interests. Sincerely, AERO-METRIC, INC. 44-61-4 Larry J. Edwards, Ph.D., P. E. Vice President, Western Division 0 TOWN of ESTES PARK Inter-Office Memorandum May 7, 1999 TO: Public Works Committee r FROM: Bill Linnane 102/ SUBJECT: Aerial Mapping Project - Letter of Complaint from Aero-Metric Inc. On March 5th, the Public Works Department received two proposals to perform the digitized aerial mapping project budgeted this year. Kucera International Company submitted a price of $80,400 for the proposal and Aero-Metric Inc. submitted a price of $134,295. Upon recommendation by the Public Works Committee and Staff, the Town Board approved accepting Kucera's proposal at the April 27~h Town Board meeting. The attached letter of complaint from Aero-Metric was received on April 30th. Aero- Metric is objecting to the following: 1. Kucera submitted the proposal 30 minutes after the requested 4 p.m. time. Shawn Kraft, Public Works Department GIS Analyst did accept Kucera's proposal 30 minutes after the RFP 4 p.m. request I did not become aware of this until the complaint letter was received. Had I known, I would have researched the legality issue with Greg White prior to the April Public Works Committee meeting. I also talked to Shawn about avoiding future proposal irregularities. On May 3rd I did discuss this issue with Town Attorney Greg White and received the attached legal opinion. According to Greg, since the aerial mapping project does not require a formal bid Oil<e the Hwy. 34/36 construction project/federal funds, etc.), the Town can waive any formalities regarding things such as late submittals. Because of this and the fact that both proposals meet the requested RFP specifications, and since Kucera is $53,895 lower than Aero-Metric, the Town is justified in accepting Kucera's proposal. 1 I , 2. The selection process did not include formal presentations by the individual companies. It is not Town policy to request formal presentations for all project proposals, even in the dollar range mentioned above. Telephone calls to several other municipalities reaffirmed that formal presentations are not typical for all projects of this magnitude. The Public Works Department knows the qualifications of both companies and both companies are excellent firms. Kucera performed our 1979 aerial mapping project and the accuracy of those maps are in accordance with the attached National Map Accuracy Standards. Since the Public Works Department is very familiar with both companies, it was decided that presentations were unnecessary. 3. The Public Works Committee did not make an informed decision. When Shawn Kraft, Richard Matzke and I reviewed both proposals, it was the consensus to choose Kucera based on the company's excellent reputation with the Town and the proposal cost For your information, Shawn Kraft has a B.S. from Oklahoma State University, with an emphasis in GIS and Photogrammetry. In addition, he was the project manager of the Crested Butte aerial mapping project Contrary to what Aero-Metric is insinuating, both proposals will result in the RFP requested accuracy. As a double check, I contacted an outside consultant who has expertise in the aerial mapping field. They reviewed each of the proposals and also the RFP that was sent to both companies. The outside consultanfs findings were that both proposals met the RFP specifications and, if both companies perform the project as stated in their proposals, accuracy will be similar, if not exact The Public Works Committee did make an informed decision. I discussed all of the above issues with John Baudek, Mayor Robert Dekker, Randy Repola and Greg White. As a result the Town will proceed with Kucera as our contractor choice. Based on all of the information above, I sent the attached letter to Aero-Metric. I also told Aero-Metric that I would give a report on this matter at the May 20th Public Works Committee meeting and that Aero-Metric was welcome to attend.

As such you have provided me with the letter and a copy of the Request for Proposal for the Adal Photography for Planemetric Database Acquisidon for the Town of Estes Park. The Town of Estes Park, being a statutory Town, is not legally required to bid any proposed project. Statutory ciries or home-rule cities whose charter requires bidding, are required to bid certain public works or projects and accept the lowest responsible bid. The Town docs not opetate under such legal requirements in its requests for work. The letter of April 26, 1999 quesdons the Town's waiver of the 4P.M. deadline as stated in the request for proposals. Since this is a request for proposal and not a formal bid situation, the Town can waive any informality in reviewing any request for proposal.

CO 80538 Fax (970) 667-2527 National Map Accuracy Standards Page lof 2 National Map Accuracy Standards The U.S. Bureau of the Budget first issued the "United States National Map Accuracy Standards," in 1941. The standards, which applied to all Federal agencies that produce maps, were revised several times, and the current version was issued in 1947. Below is a brief summary of the standards, followed by the official government-speak jargon. Summary As applied to the USGS 7.5-minute quadrangle topographic map, the horizontal accuracy standard requires that the positions of 90 percent of all points tested must be accurate within 1/50th of an inch (0.05 centimeters) on the map. At 1:24,000 scale, 1/50th of an inch is 40 feet (12.2 meters). The vertical accuracy standard requires that the elevation of 90 percent of all points tested must be correct within half of the contour interval. On a map with a contour interval of 10 feet, the map must correctly show 90 percent of all points tested within 5 feet (1.5 meters) of the actual elevation. All maps produced by the USGS at 1:250,000 scale and larger are prepared by methods designed to meet these accuracy standards and carry the statement, "This map complies with National Map Accuracy Standards." The USGS systematically tests the accuracy of its maps. Presently, accuracy testing is performed on 10 percent of the mapping projects at each contour interval as a method of controlling overall quality. It is rare for a 7.5-minute map to fail the test. Exceptions involve areas covered by dense woodland or obscured by fog or clouds. In those areas, aerial photographs cannot provide the detail needed for precise mapping. United States National Map Accuracy Standards 1. Horizontal accuracy. For maps on publication scales larger than 1:20,000, not more than 10 percent of the points tested shall be in error by more than 1/30 inch, measured on the publication scale; for maps on publication scales of 1:20,000 or smaller, 1/50 inch. These limits of accuracy shall apply to positions of well-defined points only. Well-defined points are those that are easily visible or recoverable on the ground, such as the following: monuments or markers, such as bench marks, property boundary monuments; intersections of roads and railroads; corners of large buildings or structures (or center points of small buildings). In general, what is well-defined will also be determined by what is plottable on the scale of the map with-in 1/100 inch. Thus, while the intersection of two roads or property lines meeting at right angles would come within a sensible interpretation, identification of the intersection of such lines meeting at an acute angle would not be practicable within 1/100 inch. Similarly, features not identifiable upon the ground within close limits are not to be considered as test points within the limits quoted, even though their positions may be scaled closely upon the map. This class would cover timber lines and soil boundaries. 2. Vertical accuracy, as applied to contour maps on all publication scales, shall be such that not more than 10 percent of the elevations tested shall be in error by more than one-half the contour interval. In checking elevations taken from the map, the apparent vertical error may be decreased by assuming a horizontal displacement within the permissible horizontal error for a map of that scale. 3. The_accuracy of any map may be tested by comparing the positions of points whose locations or elevations are shown upon it with corresponding positions as determined by surveys of a higher accuracy. Tests shall be made by the producing agency, which shall also determine which of its maps are to be tested, and the extent of such testing. 4. Published maps meeting these accuracy requirements shall note this fact in their legends, as follows: "This map complies with National Map Accuracy Standards." 5. Published maps whose errors exceed those aforestated shall omit from their legends all mention of http://www.cs.umt.edu/GEOLOGY/FAC/gaeuman/mapaccuracy.html 5/6/99 National Map Accuracy Standards Page 2 of 2 standard accuracy. 6. When a published map is a considerable enlargement of a map drawing (manuscript) or of a published map, that fact shall be stated in the legend. For example, "This map is an enlargement of a 1:20,000-scale map drawing," or "This map is an enlargement of a 1.24,000-scale published map." 7. To facilitate ready interchange and use of basic information for map construction among all Federal mapmaking agencies, manuscript maps and published maps, wherever economically feasible and consistent with the use to which the map is to be put, shall conform to latitude and longitude boundaries, being 15 minutes of latitude and longitude, or 7.5 minutes, or 3.75 minutes in size. http:Uwww.cs.umt.edu/GEOLOGY/FAC/gaeuman/mapaccuracy.html 5/6/99 __ev.*y TOWN OF ESTES PARK --*407 .,ef-irryi:$47/ .

Aero-Metric Inc. 4708 South College Avenue Fort Collins, CO 80525 Dear Mr. Edwards: I'd like to apologize for the circumstances you described in your letter to Mayor Dekker. I assure you that Mr. Kraft did not intentionally try to undermine the "Request for Proposal" procedure, but was attempting to receive another proposal so that a comparison could be made. 1 discussed this matter with Mr. Kraft so that future proposal requests don't have a similar outcome. I also spoke with the Town Attorney for guidance on this matter. His legal opinion is that the Town requested a proposal only. This was not a project where we were required to solicit formal bids and go through the strict requirements associated with a formal bid process. Even if a proposal is delivered after the requested time, it can be legally accepted. Kucera did meet our requested specifications, including accuracy. Due to this and the relatively large price differences, the Town will proceed with contract negotiations with Kucera. The Town staff does know that Aero-Metric is a very reputable firm with an excellent reputation. We were fortunate to have received proposals from two companies with such excel]ent qualifications. For your information, the Public Works Committee will meet again at 3:30 p.ni. on May 20th in the Town Board Room. I will give a report on the issues you brought up.
