April 26, 2000 Board of County Commissioners: Ms. Barbara Kirkmeyer, Chairperson Mr. Mike Geile Mr. George Baxter Mr. Dale Hall Mr. Glenn Vaad P. O. Box 758 Greeley, CO 80632 Dear Commissioners: We are writing this letter to advise you that we support the proposed Soaring Eagle Subdivision, north of Windsor. While our land does not directly connect with any of the boundaries of that particular property, we are within a 1 mile radius and consider it part of our neighborhood. We support the approval of this subdivision for the following reasons • The quality of the development plan is first class and will enhance the value of the entire area. • All of the criteria set forth by the rules and regulations of the county have been met and exceeded. Rules and regulations are important to all of us; however, it is our belief that when a proposed plan exceeds those requirements, approval from our representatives is to everyone's benefit. • We are already seeing land in the immediate area lay idle when it is not farmed by the owners. The current economics of agriculture are such that it is not profitable to rent additional land to raise corn, hay, beans, etc. That idle land will soon become a detriment to the neighborhood, producing more uncontrolled weeds that the rest of us will have to continually battle. EXHIBIT Board of County Commissioners Page 2 • Due to the fact that there have been no objections by land owners that directly touch the boundaries of this proposed subdivision, why, then, would a governing body reject a plan that (repeating a previous point) meets and exceeds all the rules and regulations. Thank you for the opportunity to express our opinions and the trust chat we put in you as our County representatives.

(Weld County Case #Z- 537). This report discussed separation distances of all septic leach fields from both historically high groundwater elevations, as well as areas of shallow bedrock. Also discussed is nutrient loading from pre-development and post-development land uses. I believe you will find this report to be a thorough examination of these issues and the conclusions should alleviate the concerns that have been raised. Also enclosed is a letter from Dean Smith, the General Manager of Boxelder Sanitation District. Dean has extensive background in sewage disposal,package plants for wastewater treatment., and individual sewage disposal systems. Boxelder Sanitation District is familiar with this area and considers it within their 70-year long-term service area. Based on their evaluation of our proposal, they have concluded that the only feasible option would be for Soaring Eagle Ranch to be served by an Individual Sewage Disposal System (ISDS). Please review this additional material. We arc schedule for a Change of Zone Hearing before the Weld County Commissioners on May 10, 2000 at 10:00 a.m. I believe this additional information, along with the other information that has been submitted to date, should allow you o make your formal recommendation to the Commissioners.

Mr. Stan Everitt The Everitt Companies 3030 South College Avenue Fort Collins, CO 80525 RE: Opinions Regarding Development Impacts Soaring Eagle Ranch Windsor, Colorado Project Number 1099027 Dear Mr. Everitt: The purpose of this letter is to present our opinions regarding development impacts to surface and groundwater at the above-referenced site. Our professional opinions arc based on information and literature reviewed, our experience and the proposed site conditions We have also addressed the issues raised by the Weld County Health Department in the memorandum dated February 3, 2000. It appears the primary issues relate to the separation distance between the proposed septic systems and groundwater and bedrock. We also compared nutrient loading to groundwater and surface water for the agricultural use versus the residential use. I. GROUNDWATER-SEPTIC SYSTEMS SEPARATION DISTANCE As you know, the depth to groundwater has been and continues to be monitored via a system of piezometers installed at the site by Earth Engineering, Inc. We believe that the groundwater elevations recorded prior to January 2000 are often higher than the actual groundwater surface at that time due to the fact that the piezometers were not properly scaled at the surface. In fact, the piezometers were initially constructed such that stormwater and irrigation water could enter the piezometer boring directly. Therefore, we believe that groundwater elevations recorded during irrigation activities and after rainfall events were erroneously high. These data were still used in our evaluation since they would he conservatively high and were the largest, site-specific data set available. We reviewed the grading plan prepared for the site. The separation distance between the observed historic groundwater high and the proposed leach field inverts is summarized on ENVIRONMENTAL ENLINEERINO ANI' GEOHYUROLOGY Mr. Stan Everitt/The Everitt Companies-. Soaring Eagle Ranch Project Number 1099027 PARAGON ON April 25, 2000 Page 2 Figure 1. As seen from the attached figure, the septic systems are situated in areas where at least a 7-foot separation exists between the planned finished grades and the historic-high groundwater observations for the site. A 7-foot separation from finished grades was used to account for the fact that the leach field laterals will be buried approximately two 2) feet below finished grades and Weld County regulations require a 4-foot separation d'sFance. This approach leaves a 1-foot freeboard between planned finish grades and the squired separation distance. Since the post-development irrigation rates will be significantly lower than the pre-development irrigation rates, we believe that the local groundwater elevations will be incrementally lower that the pre-development groundwater elevations for the same climatic conditions. Groundwater elevation observations will also he made during the lot- specific percolation testing to augment the observations made to date. We understand that the 8-foot test hole will be completed using a backhoe which will allow for more detailed observations of subsurface conditions than would a borehole. Therefore, we believe chat the septic systems will not be negatively impacted by high groundwater elevations and will meet or exceed Weld County design criteria for this issue. 2. BEDROCK-SEPTIC SYSTEMS SEPARATION DISTANCE We reviewed the boring logs prepared for this site by Earth Engineering, inc. and compared the observed bedrock elevations to the final grading plan prepared for the site. The separation distance between the observed bedrock and the proposed leach field inverts is summarized on Figure 2. As seen from the attached figure, the septic systems are situated in areas where at least a 7-foot separation exists between the planned finished grades and the observed bedrock elevation. Bedrock elevation observations will also be made during the lot-specific percolation testing to augment the observations made to date. We understand the 8-foot test hole will be completed using a backhoe which will allow for more detailed observations of subsurface conditions than would a borehole. Therefore, we believe 'hat the septic systems will not he negatively impacted by high bedrock elevations and will meet or exceed Weld County design criteria for this issue. 3. PRE-AND POST-DEVELOPMENT NUTRIENT LOADING Nutrients naturally enter the groundwater system and surface water systems. The on-site lake is for storage of irrigation water and stormwater runoff. We understand that pond is lined and therefore will not negatively impact groundwater quality. We understand that there is a concern that the proposed development may cause increased nutrient loading to Windsor Reservoir. Eutrophication is the natural aging process of aquatic ecosystems. Although eutrophication can occur in both river and stream systems, it is generally thought to he most important in lake systems. Lakes undergo a natural succession from oligotrophic (poorly Mr. Stan Everitt/The Everitt Companies— Soaring Eagle. Ranch Project Number 1099027 PARAGON April 25,2000 Page 3 nourished and lacking in plant nutrients) conditions to eutrophic (very productive) conditions due to the influx of sediments and nutrients from the surrounding watershed and drainage system. Eutrophication may be accelerated by human activities such as agriculture, urbanization and increasing the rate of soil erosion and sedimentation. The subject site has • historically been operated as a farm producing a variety .of crops including corn, wheat, alfalfa, beans and beets. A portion of the site has also been operated as a feedlot and cattle grazing has been allowed on the property. The method for estimating nutrient loading was taken from Landscape Planning and Environmental Applications, Second Edition by William M. Marsh. Marsh used the widely- accepted reference by J.M. Omernick entitled Nonpoint Source - Stream Nutrient Level Relationships published through the Corvallis Environmental Research Laboratory by the United States Environmental Protection Agency (EPA). Omernick's values for nitrogen (N) and phosphorus (P) loading were derived from a study of 904 watersheds in the Western, Central and Eastern United States under a variety of land-use conditions. We used Omernick's N and P loading values for "agricultural" land use (defined as greater than 75 percent active farmland) for pre-development conditions; and Omernick's N and P oading values for "mixed use" for post-development conditions. The mixed use category appeared to most resemble post development at the site, since only approximately 52 acres out of the approximately 384 total acres (approximately 13 percent) are proposed to be developed residentially. Omernick's category of "urban" required greater than 40 percent urban development. It should be noted that we also reviewed N and P loading references diced in the EPA's Total Maximum Daily Load (TMDL) Program. The EPA TMDL N and P loading references were consistent with Omernick's, but were actually somewhat lower than Omernick's; therefore, Omernick's values were used as a conservative case. For the entire site, pre-development N loading as a result of run-off was estimated to he approximately 3,360 lb. N per year; and post-development N loading as a result of run-off was estimated to he approximately 1,889 lb. N per year. Similarly, pre-development P loading as result of run-off was estimated to be approximately 106 lb. P per year; and post- development P loading as a result of run-off was estimated to be approximately 63 II. P per year. We also estimated N and P contributions to Windsor Reservoir from the septic systems proposed for the site. Per Marsh, the loading potential from septic drainfield seepage is based on the number of'homes within 100 yards of the shore of Windsor Reservoir or stream bank, multiplied by nutrient loading rates given in his reference. Please note that the Weld County setback distance is 100 feet and the site-specific setback informally agreed to by you Mr. Stan Everitt/The Everitt Companies-- Soaring Eagle Ranch Project Number 1099027 PARAGON April 25, 2000 Page 4 is 200 feet versus the 100 yards used in this analysis. For the Soaring Eagle Ranch, only eight (8) of the 114 lots were identified as being approximately 100 yards away from the shore or stream bank. Of these, six (6) were located along the Larimer and Weld Canal which appears to be topographically higher than the proposed leach fields for these lots. Therefore, on-site surface water runoff will be away from the canal and will not impact canal water quality. For a conservative case, the eight (8) lots were used to estimate N and P contributions from the septic systems. N loading as a result of these septic systems was estimated to be approximately 188 lb. N per year; and P loading as a result of these septic systems was estimated to be approximately 5 lb. P per year. Summing the contributions from both run-off and septic systems, post-development N loading was estimated to be approximately 2,077 lb. N per year which is approximately a 38 percent reduction from the estimated pre-development N loading rate. Total post- development P loading was estimated to be approximately 68 lb. P per year which is approximately a 36 percent reduction from the pre-development P loading rate. 4. POST-DEVELOPMENT FACTORS AFFECTING NUTRIENT LOADING The following are several development factors which we believe will reduce the rate of eutrophication of the Windsor Reservoir. • The Soaring Eagle Ranch has several features which should reduce nutrient loading ;o the reservoir. Based on the proposed grading plan for the site, it appears that the Soaring Eagle Ranch will significantly reduce sheet flow that currently enters the reservoir. These flows will in turn be diverted to the lined irrigation/retention pond located in the center of the development. A reduction in sheet flow to Windsor Reservoir should decrease the sediment load entering the reservoir which should in turn reduce nutrients entering the reservoir, especially phosphorus. Phosphorus in the form of phosphate has been implicated as one of the limiting nutrients in freshwater aquatic systems. !t has been estimated that sediment particles can transport two (2) to five (5) time:; more phosphate than the dissolved P load. • Per the site's development guide, total irrigation at the site will be significantly reduced from approximately 380 acre feet per year for the current farm to approximately 11 I acre feet per year for the development. The reduction in irrigation should also reduce nutrient and sediment loads that would have been returned to the reservoir in irrigation tail water. • The planned individual septic systems also have several design and management Ieatures which enhance their long-term viability for domestic sewage disposal. A significant Mr. Stan Everitt/The Everitt Companies—Soaring Eagle Ranch Project Number 1099027 PA R CI ON April 25, 2000 Page 5 design feature is the ability to alternate the use of 50 percent of the total leach field each year, allowing the remaining 50 percent of the leach field to "rest" and be ventilated. Inspection, operation, maintenance and alternating the leach fields each year will he the responsibility of the Home Owners' Association. In addition, the Home Owners' Association will pump out the septic systems on a 4-year schedule. These activities are specified and budgeted for in the covenants for the community. • The alternating leach field design feature is considered state of the art for individual septic systems and should enhance treatment of domestic sewage and significantly increase the life of the septic systems. Additionally, each lot has a second septic system envelope that could he developed in the unlikely event of septic system failure. • The EPA's 1997 Response to Congress on Use of Decentralized Wastewater Treatment Systems states that there are several benefits of decentralized wastewater treatment systems. The EPA's report states that these systems can protect the public health and environment as well as centralized systems when properly managed. The most common factor in septic system failure is a lack of maintenance which is typica the responsibility of an individual home owner. This problem is alleviated at the Soaring Eagle Ranch because the management of the systems is controlled by the Home Owners' Association. • The EPA report states that decentralized systems are usually appropriate and most cost effective for low density communities in rural areas. The septic system density of the subject development is approximately one (1) system per approximately 3.3 acres which appears to be relatively low. 5. SUMMARY In summary, we believe that the proposed septic systems: • Meet or significantly exceed Weld County regulations regarding leach field and groundwater separation distances; • Meet or significantly exceed Weld County regulations regarding leach field and bedrock separation distances; and • Will have a lower N and P loading to both groundwater and Windsor Reservoir than the existing land use. • In addition, significant steps have been taken during the planning process to protect the integrity of the septic systems and to protect and enhance the quality of local groundwater and surface water systems.

College Fort Collins, CO 80525 Dear Mr. Everitt: The Everitt Companies approached Boxelder Sanitation District for potential service to their proposed Soaring Eagle Ranch subdivision. The proposed subdivision, with 114 lots on 183 acres, is situated on State Highway 257, about 3.5 to 4 miles north of the town of Windsor. This area lies in what the District considers its 70-year long-term service area. The District, with its current facilities, would be unable to serve the said subdivision in the near-term. However, in the far, long-term, the District may be able to serve the said subdivision. An alternative would be for the subdivision to be served by Windsor's wastewater treatment plant. However, the said subdivision is well north of the Windsor service area limits for wastewater collection and treatment, as submitted to the North Front Range Water Quality Planning Association (NFRWQPA), so this option appears to be questionable. • This leaves two other alternatives: a community wastewater treatment plant (WWTP) such as a package plant, or individual sewage disposal systems (ISDS). When it comes to package plants, Boxelder Sanitation District takes its cue from CDPHE-WQCD (Colorado Department of Public Health and Environment---Water Quality Control Division), whose personnel are of the general opinion that such facilities are difficult to run, are often out of compliance with discharge limitations, and one should try to avoid their use and, instead, seek consolidation of many such smaller facilities into larger plants. In fact, there are other undesirable aspects of such a facility for the aforementioned subdivision. These include the apparent lack of a good receiving stream for effluent, the challenges of obtaining an NPDES (National Pollutant Discharge Elimination System) permit for such a treatment plant, and the general economic factors associated with cuiistimaing and operating sueh a facility. If tho Dietrict were to be asked to take over a package plant, operate it, and take liability for its long-term performance, I believe the Board would decline to do so for reasons mentioned above. .... ., , n:_.._.. A..- trQ snr,92 Everitt Enterprises April 20, 2000 Page 2 In our opinion, the only feasible option would be for the subdivision to be served by an Individual Sewage Disposal System (ISDS). While it is not in the economic interests of the District to have its service area be host to ISDS based developments, the alternatives to ISDS are quite unpalatable at this point in time. A quick comparison of published costs for centralized wastewater treatment plants versus ISDS is worthy of consideration. A recent publication from the U.S. Environmental Protection Agency Response to Congress on Use of Decentralized Wastewater Treatment Systems presents a comparison between a centralized wastewater treatment facility and an ISDS type arrangement for a rural community of a size nearly similar to the aforementioned subdivision. It is reproduced below. SUMMARY OF RURAL COMMUNITY TECHNOLOGY COSTS: Note: Rural Community = 135 homes on 1+ acre lots Technology Option: I Total Capital Annual O&M Total Annual Cost: Cost: Cost: Centralized System $2,321,840 to $29,740 to ' $216,850 to $3,750,530 $40,260 $342.500 Onsite System $510,000 $13,400 $54,500 _ In addition to the constraints mentioned above, the economics of an ISDS are much more favorable than a centralized wastewater treatment system. In conclusion, it is the District's opinion that at this point in time, ISDS would be the most practical and economically feasible means of wastewater treatment for the proposed subdivision. As Boxelder's collection and treatment systems expand, perhaps at a point in the future the District might be able to serve the subdivision with 2 centralized wastewater treatment plant. Until such a time, however, the subdivision would be best served by an ISDS. If you have any questions on this matter, please do contact me. Sinc r y, W.

As you know, the Division of Wildlife becomes involved in providing review of development proposals in the county referral process. Often, when the DOW reviews a project, significant amounts of rime and resources have already been invested in the design that can make changes difficult to make, Early wildlife planning results in fewer changes, identification of habitat impact issues early in the process and an overall design that benefits all. The Division of Wildlife's role is not to support or oppose any individual development, but through both internal policy and statute, serves in an advisory capacity by providing input on wildlife impacts on certain developments, and advice on how to minimize, avoid, or mitigate those impacts. You approached the Division of Wildlife in July of 1999 to request wildlife input on a concept plan for the Soaring Eagle Ranch subdivision. The Division of Wildlife commented on several concerns regarding impact to wildlife on this project. Those concerts related to Canada goose impact, eagles, and a wetland slough. Canada geese use the closure both for winter resting on the reservoir and undisturbed feeding in the grain fields within the closure. Soaring Eagle Ranch will remove some of these grain fields from feed production. Some of the displaced getse will move into Greeley, Windsor and Fort Collins. Many of the geese will probably remain in the area and adapt to the Ranch. The Division also expressed recommendations to minimize goose presence within the subdivision. Geese find bluegrass lawns and ornamental to be attractive. Your current design, with native grass plantings, helps deal with this problem and is the right way to begin to approach nuisance management, As the Fort Collins, Windsor, Greeley area continues to develop and grow, planning departments in DEPARTMENT OF NATURAL RESOURCES,Greg Welcher,Executive Deader WILDLIFE COMMISSION,Chuck Lewlti,chairman•Mark LeValley.Vice-Chairman•acrnard L.Block Jr.,Secretory Rink Enalrom.Member•,Phbip James Member•Mariann Rehepouloa,Member Arnold Salazar,Member•Bob Shoemaker,Member •Oreg Welcher,Non-Voting Member •Don Amore Non-Voting Mambo, MAY-08-2000 MON 04:21 PM EVERITT COMPANIES FAX NO. 19702234158 )?

This problem will continue to grow as the area develops. Hunting of geese in the area was also a concern of the Division of Wildlife. Hunting around the closure has been a traditional form of recreation in the area and serves to help effectively keep the goose population in check. You expressed a willingness to work with the county or appropriate entity to advise new residents of the hunting activity and it's importance, and either through deed language or other recorded instrument, gain agreement not to object to goose hunting in the surrounding agricultural areas. I encourage you to continue working to support goose management through (writing in the area, I also applaud your leading efforts in the Fossil Creek Reservoir area in setting aside significant acreage that will be managed to provide grain food sources for wintering geese, The Division of Wildlife commented on the use ot'the area by bald Eagles. There is a grove of trees on the west shore that is used as day hunting perches by eagles in the winter. We recommended creating a buffer by removing development in lots 25 through 29. Your current design has removed three of the five lots, and although this current plan will result in eagles probably still using the area, further buffers in the other two lots would help provide greater confidence in there use of the trees. it is difficult to predict the comfort level of eagles when encroached by human activity. The. fact that there is no access to the shoreline from the development will benefit both eagle and goose management, The final concern the Division of Wildlife expressed was regarding a wet slough adjacent to the subdivision. This wetland had a trail running through it and had lots immediately adjacent to it, The Division recommended a forty-foot setback from the slough and elimination of the trail that bisected it. Your current plan has been modified to reflect those concerns. In closing, I appreciate the efforts you have made in proactive planning for wildlife and your afforts to address the Division of Wildlife comments made on October 15, 1999, Any time that development takes place in wildlife habitat, there will be negative impacts to the wildlife. Your effort to try and minimize those impacts is appreciated. 41:1_ • ar Area Wildlife Manager 1O9 r'ollins, Colorado 4 MEMORANDUM l �' iglikTO: Julie Chester, W.C. Planning DATE: May 3, 2000 FROM: Pam Smith, W.C. Health Department tr,, COLORADO CASE NO.: Z-537 NAME: George Nelson Farms/Soaring Eagle Ranch The Weld County Health Department has reviewed this proposal. A member of our staff has also observed the site. The application has satisfied PUD Ordinance No. 197 in regard to water and sewer service. /Vater will be provided by the North Weld County Water District and sewer will be provided by septic systems. The proposed lot sizes (minimum of 1.75 acres) and the overall density of septic systems per acreage (1 per 3.42 acres) complies with Ordinance No. 197 and our Departmental policy. The environmental impact plan provided in the application materials and required in section €. S.1 of the PUD Ordinance appears to address all potential impacts described in the Ordinance. A review of the soil data to date reveal that the site is marginally suitable for individual sewage disposal systems. However, the applicant submitted documentation regarding conceptual grading plans to this Department on April 26, 2000. This information compares the relationship to groundwater and bedrock separation and suitability for individual sewage disposal systems, and compares pre-and post- development nutrient loadings on the proposed PUD. The concerns with groundwater and bedrock separation appear to be adequately addressed, provided the applicant follows the conceptua grading plans. The Department requested the applicant to provide a study of feasibility for either community sewerage or for the construction and operation of a package treatment plant for the PUD. The applicant enclosed a letter from Dean Smith, Boxelder Sanitation District, on the District's opinion of what the Colorado Department of Public Health and Environment's position would be regarding the construction' and operation of a package treatment plant. No documentation was provided directly from tt e Colorado Department of Public Health and Environment, which would be the regulating author ty on the construction and operation package plants. The Department recommends that the following items be place on the Plat as a condition of approval 1. The applicant shall obtain water service from the North Weld County Water District. 2. Primary and secondary septic system envelopes and a building envelope were not designated on each lot. Septic system envelopes should meet the setback to the Eaton Ditch as well as other required setbacks as described in the Weld County Individual Sewage Disposal System Regulations 3. Language for the preservation and/or protection of the second absorption field envelope n the development covenants. The covenants should state that activities such as landscaping (i C. planting of trees and shrubs) and construction (i.e. auxiliary structures, dirt mounds, etc ) are expressly prohibited in the designated absorption field site. .‘eId County PL i r oqg u j. EXHIBIT t. CASE NO.: Z-537 NAME: George Nelson Farms/Soaring Eagle Ranch Page 2 4. Each septic system shall be designed for site-specific conditions, including but not limited to maximum seasonal high groundwater, poor soils, and shallow bedrock. 5. In the event that 5 or more acres are disturbed during the construction and development of this site, the applicant shall obtain a storm water discharge permit from the Water Quality Control Division of the Colorado Department of Public Health and the Environment. Silt fences shall be maintained on the down gradient portion of the site during all parts of the construction phase of the project. 6. During development of the site, all land disturbance shall be conducted so that nuisance conditions are not created. If dust emissions create nuisance conditions, at the request of the Weld County Health Department, a fugitive dust control plan must be submitted. 7. In accordance with the Regulations of the Colorado Air Quality Control Commission any development that disturbs more than 5 acres of land must incorporate all available and practical methods which are technologically feasible and economically reasonable in order to minimize dust emissions. a) If land development creates more than a 25 acre contiguous disturbance, or exceeds 6 months induration, the responsible party shall prepare a fugitive dust control plan, submit an air pollution emissions notice, and apply for a permit from the Colorado Department of Public Health and Environment. 8. The "Right to Farm" covenant shall be placed on the plat. 9. The site grading plan as outlined in documentation from Northern Engineering Services Inc.

I am Tom Cullison, Manager of Cullison Family Farms, LLC. I wanted to let you know how we at Cullison Family Farms feel about the future of the farm land we own. My dad (Emerson Cullison deceased 1997)was the last family member to farm &that was in the early 40's. At the age of 80 (1988) he turned the running of the farms over to me. We share crop with a farmer (our share of crops is his rent for the farm). It has been since the 70's &early 80's since the farm made good money for the family. The last four years our average net income prior to taxes has been $13,702. Plus our property tax went up 13.5% in 2000 from what it was in 1999 ($6,388 to$7,254). Our cost to just use our water went up 58% ($3,100 to $$4,900). a least twice in the last few years we have had to wait to after the 1st of year to find out if the farmer's bank would carry his loan for the next year. My older sister is retired and would like to move to Ohio to be close to her children & grand children. She can't afford this if we don't sell. I lost my brother at age 50 (Diabetic w/heart problems) in 1951. We have decided that we will try are darndest to sell the farms for the best price we can get. None of us are in favor of keep- ing the farms. I really believe that Stan Everett of Everett Companies has a great plan for that area. If this falls through, we will all survive, but we will still try and sell the farm(s)for the best price. I have two other parties interested if the deal with Everett falls through. Early on a Real Estate Developer from Loveland contacted me, and I have had an Inquiry from Best Buy Homes, LLC of Carbondale Colorado. although I believe the later is more interested in the water rights then developing they did state that they would also consider the land. I wouldn't have a problem selling the land as farm land, but not to many farmers will be able to afford that kind of cost. I'm attaching a copy of the letter I made up for the county(Planning & Commissioners) on December the 2nd of 1999. Thank you for your time.

A part of this proposal is on our farm land. I hold that the sanctity of private property rights was a cornerstone in the founding of our country. The growth of our country, including its network of highways and infrastructure, has been most effectively accomplished when the private sector is allowed to proceed with minimal interference from government. One of the challenges of growth has been the balancing of the rights and interests of the public and private sectors. An unfortunate result of this balancing process is the increasing tendency of government to weigh in on the perceived side of the public good often resulting in the diminishment of private property rights and values. This includes over-reaching land use regulations, exaction and other limitations that significantly diminish private property rights without compensation. There is wide concern of increasingly significant intrusions by government into the rights of farmers and their right to sell their farm land at the best possible price available. If government is going to require open space or a "Save the Farms" philosophy, then the land owner should be compensated for any losses he might incur due to decreased property values. The building and development industries are two of the more heavily regulated industries. Both businesses require significant capital, long range planning and vision, all of which can be significantly affected by a burdensome and often subjective regulatory environment. The ability to deliver quality housing and a product to market requires stability in several areas, including the regulatory environment in which the businesses must be conducted. Yet the regulatory environment in which business is conducted tends to be volatile and in many cases subjective, making it increasingly difficult to operate within. The building and development industries and government agencies must work with each other to establish a trusting working relationship. Quality developments in our communities are goals sought by both private industry and the government, and can only be attained by an attitude of trust and respect for the roles of each in the process and not by the creation of an adversarial environment. Despite sincere efforts by the private sector and government to establish this relationship, there will be times when such efforts are unsuccessful. If a breakdown in this relationship occurs resulting in an unacceptable intrusion into private property rights, then there should be methods that allow a speedy resolution to determine whether government has exceeded its authority, and, if appropriate to compensate the private FCAROL Harding - 05/10/00 -Docket#2000 21, PL1408 Chg Zone Ag to PUD Page 31 property owner for the losses suffered.
