The Engineer will observe the sam.q~ng, take possession of the samples, and retain these samples for possible testing. Sample size shall be a m~nr~t.m of 9 kg (20 pounds). If a 10,000 ton sample fails then the four 2000 ton samples from the area representec :,, :hat failing 10,000 ton sample will be tested for moisture susceptibility. The 10,000 ton result and the four 2,00: cn result will be considered a lot of five and will be evaluated according to the formulas and procedures in SUDS~:Ion 105.03. If less than four retained samples are on hand because the t0,000 ton sample represents less Fan 8000 tons of hot bituminous pavement, the price adjustment will be based on the test results from the retame~ samples on hand plus the test result from the 10,000 ton sample.

While we have always been supporters of the affordable housing program, as concerned observers now, we believe proceeding with the City's Burlingame Project would be a mistake. Summary: There are serious questions regarding the legality of commitments by the City in the proposed annexation which will likely lead to referendums or court challenges. It is a mai-administration of public assets to propose the taxpayers install $2.5 million of new roads at this time. This City is also planning to install another $6 million in utility lines and infrastructure for that project. The current two cash flow analyses show a direct loss to the taxpayers of $12 or $22 million to build this project. Those losses should be much more precise. Many indirect costs have not been identified or determined. It is irresponsible to proceed with any infrastructure contracts before the project plans are complete and all the direct and indirect project costs and taxpayer losses are determined and disclosed, and approved by fully informed voters. Such expenditures will be wasted if the project is disapproved by the courts or the voters. There are enormous undetermined and undisclosed taxpayer subsidies and concessions to the adjacent private developer Zoline, for a large home development, given in exchange for 20 acres for the Burlingame project, so it is not possible to determine if the City is overpaying for land. Approximately 30% to 40% of the affordable housing is being built at the City's cost for the affordable housing required for Zoline's development. The original plan projected 185 employee units selling for less than $260,000 at a taxpayer loss of $22 million.. The more recent COWOP plan, which projected (only) a $12 million loss; halfed the number of such units and would only meet the affordable housing required for the Zoline development, and would not reduce the existing housing deficit for lower price units. The Burlingame project is bad planning in a bad location and better alternatives exist. Contracting for road and utility extensions at this time prejudices the City's and the voters ability to terminate this project at less cost. Illegal or Questionably Legal Acts by the City: The TABOR amendment (Taxpayer's Bill of Rights) to the Colorado Constitution requires an election to approve the creation by a city of any multi-year direct or indirect financial obligation whatsoever without adequate present cash reserves pledged irrevocably and held for payments of that financial obligation in all future years. The costs of this affordable housing project are a multi-year financial obligation for which there are no adequate present cash reserves pledged irrevocably and held for payments in the future years. To proceed with this project will require a TABOR election. A citizen lawsuit for violati on of TABOR can be filed within three years of the expenditure, to request a court order that the city return the unlawfully expended funds and the citizens attorney's fees and costs. Cities are only allow-ed to annex land that is urban or will be urbanized in the near furore, Colo. Rev. Stat. 31-12-103 and 104. Urban development is defined as residential, institutional, commercial and similar uses in contrast to use of land for growing crops, grazing of farm animals and other agricultural pursuits. The original Pre-Annexation Agreement in paragraph lb., stated that the adjacent Zoline land not used for large home sites could be operated as a cattle ranch, which is not an urban use and is incompatible with 'the adjacent Burlingame housing. To conceal that this property is not to be urbanized land, the Amended and Restated Pre-Annexation Agreement, deleted reference to an operating cattle ranch, and in paragraph 1 .c. substituted that the Zoline land not used for home sites would be designated conservation which coincidently allows grazing cattle and raising hay. The Pre-Annexation Agreement contractually committed in great detail substantially all development outcomes for the Zoline property including the number and location of lots and building envelopes, building floor areas, easements, mapping, landscaping and fencing. Any meaningful development review process has been foreclosed by the Pre-Annexation Agreement which circumvents the City's normal planning process and contemplates the end result of the Zoline land use approval before any public review, and guarantees the outcome regardless of what might occur in the i:eview process, making that process an empty exercise. The state statute provides that changes to regulations of a general nature applicable to all property in the City are not precluded by a vested right (the right to construct a development as approved by a site specific development plan) and may be changed by a town at any time. Contrary to the statute, the City has purported to freeze its zoning code for the Zoline property for such city-wide regulations as the measurement of floor area, the definition of accessory dwelling units, and site review standards. Vested rights only last 3 years and extension of that period is subject to referendum. The Amended and Restated Pre-Annexation Agreement, paragraph 1 .c.9.allows Zoline a 25-year vested right, preventing future City councils from later applying appropriate zoning. The City Charter at Section 13(a) prohibits Council from selling public real property in Use for public purposes or open space purposes without an election. There are plans to liqui&ite City owned real property to raise funds to use towards the costs of the BUrlingame project Page 2 Direct which sale would require an election, which the City is not planning to conduct. Colorado Constitution, Section 1, Article XI provides that no city shall "... become responsible for the debt, contract or liability of any person, company, or corporation." In the Pre,Annexation Agreement the City committed to pay the Zoline developer's fees and costs for annexation, re-zoning, development plans, plats and costs to design, engineer and install the roads and utilities, and the multi-million dollar costs of the Zoline's affordable housing obligation required by the zoning, all of which are normally the land developer's obligations. That appears to be an unlawful assumption of the developer's obligations. Colorado Constitution, Section 2, Article XI, provides "Neither the state, nor any county, city, town, township or school district shall make any donation or grant to, or in aid of, or become ... a joint venture with any person, company, corporation, except [for activities not present here] ...' The City in the Pre-Annexation Agreement makes multi-million dollar donations or grants from its taxpayers to the Zoline's development costs and affordable housing obli gation, and agrees to submit a joint development application and to jointly plan the affordable housing and free-market project components (i.e., a prohibited joint venture). The City is proposing to construct the affordable housing units and then sell the units to private purchasers at a 12 to 22 million dollar taxpayer loss, which also appears to be an unlawful "donation or grant" to the purchasers. Losses to Taxpayers and Other Unquantified and Undisclosed Losses: The cost estimates for construction of the project are 57 to 61 million dollars and will result in a 22 million dollar net loss to the taxpay~ers if the 220 units are built or a 12 million dollar loss if the 330 units are built. (Table 8 of Burlingame Ranch cash flow analysis.) Planners assume an average of 7 to 10 car trips a day from a residence to work, school, shopping and errands, or 2300 to 3300 trips each day from 330 units, which will result in need for additional parking spaces in town (costs to the taxpayers for which have not been quantified :${* included in the project pro forma) and Will result in costs to residents to maintain and operate cars (which costs to residents will exceed $500,000 a year). While there is a desire to serve the project with frequent bus service, the diversion of car trips to transit seldom exceeds 30%. The costs of'that bus service fs another unquantified and undisclosed taxpayer subsidy. For comparison, the taxpayer subsidy for the Maroon Creek bus service, a much shorter route, costs $870,000.00 per year. In the Pre-Annexation Agreement the City has committed the taxpayers to multi-million dollar direct and indirect public costs, subsidies and concessions to Zoline for a large home development in exchange for a 20 acre parcel adjacent to the City-owned Burlingame Ranch to be used for part of the affordable housing project. These direct and indirect taxpayer and public costs must be quantified and disclosed and compared to the cost of merely buying 20 acres for this or a similar project to determine whether the City is overpaying for the 20 Page 3 acres. Some of those costs, subsidies and concessions are listed in the following section. Taxpayer and Public Costs, Subsidies, and Concessions Given in Exchange for 20 Acres: The recent NWCOG study shows large second homes create enormous growth impacts. Normally an annexing developer is required to cckmply with growth management~ and must provide additional affordable housing and other mitigation of community growth impacts to prevail i-n the growth management competition. However, the City exempted the Zoline development from growth management. The Amended and Restated Pre-Annexation Agreement, para~aphs 1.c. 1 and 2, allows the Zoline property to be developed into 12 free-market lots each with a 7,000 to 10~000 square foot residence. Paragraph 1.3.1 allows 4 new free-market houses on proposed Lot F of 15,000 to 18,000 square feet. Paragraph 10 allows the 4 houses on Lot F to later be subdivided into separate lots. Each large house also has a separate accessory dwelling unit which need not be rented and can be used as additional residence floor area or guest quarters. Also, two cabins and an RO lot can be developed; for a total of 35 residences. The community costs and impacts of that growth are not quantified or disclosed. Paragraph 1 .d, requires the City at its cost to build the affordable housing required by zoning as mitigation for the Zoline large home development. The obligation is based on a proportion of 70 affordable housing bedrooms for each 30 free-market bedrooms. It is likely the large houses in the Zoline development would have altogether at least 100 bedrooms (although there is no limit on the bedrooms). The City has agreed to assume what is normally the developer's obligation toconstruct the 70/30 proportionate number of affordable housing bedrooms which is 233 bedrooms or approximately 90 units (assuming the Zoline property has 100 free-market bedrooms), at a loss to the City taxpayers of 3.2 to 6 million dollars° (a proportionate amount of the total loss listed in Table 8 of the Burlingame cash flow analysis). Paragraph 1.h requires the City to pay all of what is normally a developer's costs for documents, studies and fees for the Zoline annexation petition and the plat, Pre-Annexation Agreement, rezoning application, zoning amendments and zoning code amendments for the Zoline development, which costs to the taxpayers have not been quantified or disclosed. In paragraph 1.h.e' the City agrees to pay the costs of all roads, utilities, to serve the Burlingame project and the Zoline property including any increase in size of service necessary to serve Zoline (costs estimated at 8 million dollars). Zoline will repay the City up to 25% of such costs depending on the number of units ultimately developed by the City. As noted above, the original Pre-Annexation Agreement granted Zoline a special variance to allow continued operation of a cattle ranch within the City limits on the portion of that propertynot developed into large home lots. The obvious purpose is to allow Zoline to retain a very low agricultural tax rate on that parcel. The cost to the taxpayers of lost future taxes Page 4 for the community have not been quantified or disclosed. In paragraph 4.b. the City agrees at to condemn access for the Zoline property through the Soldner property at the City's cost. That cost is not quantified or disclosed. The costs to the taxpayers of the City assuming these direct costs normally paid by a developer and the indirect costs to the taxpayers from the City waiving or absorbing or mitigating Zolines growth impacts and allowing Zoline to retain a low agricultural tax rate have not been quantified or disclosed. Until those costs are identified and disclosed, it is impossible to determine whether the City is overpaying for the 20 acres. As a comparison the a4iacent 181 acre Burlingame Ranch was purchased by the City 8 years ago for 2½ million: Just the cost of the City assumption of the Zoline developer's affordable housing obligation will incur a taxpayer loss of 3.2 to 6 million dollars. There are other indirect costs to pursue the project that, while not reducible to taxpayer dollars losses at this time, may nevertheless result in costs and negative impacts on the community. In paragraph 19 the City agreed to vigorously defend at its cost any of its citizen's challenges to the proposed annexation, including the free-market interests of Zoline. In paragraph 9 the City purports to surrender the rights of its citizens to enforce any land use Code violations against the Zoline development. In paragraph 1 .d the City agrees to restrict further development on its existing Burlingame ranch property to a maximum of 80 units on the back bowl, prohibiting in perpetuity the future use of the land already owned by the City, regardless of future needs. The losk 'of value to the balance of the City land has not been quantified or disclosed as a project cost. In paragraph 1 .h.d the City surrenders its right to ever locate any public trail s through the Zoline property regardless of future necessity that may not be foreseeable today. In paragraph 2.g the City surrenders the normal code requirements for street paving, lowering the developer's cost but increasing air borne dust. In paragraph 1.c. the City agrees to vacate Stage Road as a public road through the Zoline property which will financially adversely impact the Harveys and the Caudills if they subsequently develop their properties. Bad Planning, Bad Location and Better Alternatives: The 2000 Aspen Area Community Plan listed 15 potential affordable housing sites, at least 7 of which have not been further explored. The BUrlingame Ranch was not identified as one of those potential affordable housing sites, but was merely listed as an area for the community to continue to discuss for such use if it is unable to meet its affordable housing needs at the other identified, approved and agreed-upon locations. Instead, the City proposes to shelf the recent 2000 Aspen Area Community Plan and the Page 5 identified housing locations and create classic "sprawl" of a new high density suburb with approximately 1000 residents in what is now an agricultural area. The location east of Deer Hill (the hill east of the AABC) is remote from schools, stores or the downtown employment areas (it is 4.3 miles from the Hotel Jerome)4 The project of 220 or 330 units is very high density to be on just 25 acres, raising quality of life concerns. For comparison, Aspen Village has 146 units located on 33 acres. Most of the 330 unit project would be sold for $255,000 or $351,000 beyond the means of the average employee (Table 8 of Burlingame cash flow analysis). If the City Council feels the housing deficit requires a project of this magnitude, other more viable locations should first be considered. For example alternative analysis could consider a housing project at the Moore property across Maroon Creek Road from the school running track., or in a portion of the Moore open space property between Highway 82 and Maroon Creek Road. Both those properties are in walking distance of all the schools and recreational facilities at Islin Park and are within 1¼ miles of the Hotel Jerome and the downtown employment areas, on a existing road and transit route, utility and trail alignments~ requiring no additional public expenditures. The cost of roads and utilities for Burlingame are more than $8 million dollars and transit costs will add $1 million dollars a year in costs. Costs to Terminate the Pre-Annexation Agreement: There have been significant misrepresentations previously made by advocates of the project regarding supposed costs to the City in the event the Pre-Annexation Agreement is not pursued° Contrary to those assertions, if counci! should decide not proceed with the annexation, paragraph 5 of the Amended and Restated !~re-Annexation Agreement provides the City is only obligated to repay Zoline its costs and attorneY's fees incurred for the agreement and negotiations. Is the pressure to prematurely contract for road and utilityextensions-- before the project plans are finalized and costs identified --a disguised attempt to prejudice the City's ability to take advantage of the low cost termination clause? Or to prejudice the taxpayer's ability to fairly and completely assess the acceptability of this project? Very truly yours, Page 6
