Attached is my calculation for the collateral. It does not match the amount that they have on the SIA or on the exhibit. Which by the way are both different. The amount in the SIA and exhibit should be the same.

October 4, 2019 Greg Barnes Adams County Community and Economic Development 4430 South Adams County Parkway, Suite W2000A Brighton, CO 80601 RE: Country Club Ranchettes Final Plat, PLT2019-00005 TCHD Case No. 5869 Dear Mr. Barnes, Thank you for the opportunity to review and comment on the resubmittal of the Major Subdivision Final Plat to create 56 single-family lots located at the intersection of 162nd Avenue and Hayesmount Road. Tri-County Health Department (TCHD) staff previously reviewed the application for the first and second submittal of the Major Subdivision Final Plat and in letters dated April 11 and June 19, 2019 responded with comments. After reviewing the resubmittal materials, TCHD has the following comments. Pipeline Easement The plat no longer indicates a 50’ easement for a pipeline. If the pipeline easement remains, TCHD is concerned about the safety hazard posed by the gas line, in the event a contractor or property owner damages the line during construction. In addition, the pipeline easement limits the area available for construction of on-site wastewater treatment systems (OWTS) on some of the lots. The lots on which the pipeline presents a safety hazard include: lots 12-16, 39-45, and 49-56. To address this concern, we recommend signs and advisory notices to the affected property owner. On-Site Wastewater Treatment Systems The pipeline limits available area for OWTS on several lots including: 12, 14, 15 and 45. In order to ensure that these four lots can accommodate an OWTS, TCHD investigated the soil types in the area. Upon review, TCHD has determined 3,000 ft2 is an appropriate size for an OWTS envelope (primary and replacement OWTS) on each lot. The applicant shall submit plans with envelopes for both the residence and OWTS on each of these lots to ensure they can properly be served. In addition, TCHD recommends a plat note be included to inform prospective purchasers of the four lots about the pipeline easement and its impact on OWTS. An example plat note would read:

Country Club Ranchettes Resubmittal October 4, 2019 Page 2 of 3

The areas indicated on Lots 12, 14, 15 and 45 for On-Site Wastewater Treatment Systems (OWTS) are to remain free of any improvements, e.g. irrigated landscaping, paving, horse corals, out-buildings, etc.

Until TCHD receives a site plan with envelops for lots 12, 14, 15, and 45, TCHD cannot provide a favorable recommendation for service of lots 12, 14, 15, and 45 by OWTS. TCHD is available to meet with the applicant to discuss our recommendations. For the remaining lots, TCHD has no objection to the proposed subdivision being served by OWTS provided that they are properly permitted, installed, and operated in compliance with our current OWTS regulation.

Water Service TCHD does not have record of a “will-serve letter”. To ensure the subdivision can be served, TCHD requests to see a “will-serve” letter from the Great Rock North Water and Sanitation District. Drainage Easement A drainage easement is shown on Lots 13, 20, and 47-56. Plat note 7 addresses drainage easements and prohibits construction of improvements within those easements. Since the easements comprise a significant portion of those lots, and OWTS appear to be prohibited in those areas, we recommend that the applicant clarify whether OWTS are prohibited in the drainage areas. If OWTS are prohibited in drainage areas, we recommend the plat note specifically mention that OWTS are prohibited. If OWTS are allowed in drainage areas, we recommend the plat note state that OWTS are allowed, or allowed with conditions. On-Site Wastewater Treatment Systems (OWTS) – Responsible Management Entity Proper wastewater management promotes effective and responsible water use, protects potable water from contaminants, and provides appropriate collection, treatment, and disposal of waste, which protects public health and the environment. Maintenance of OWTS is often ignored or neglected. Many owners of properties served by OWTS are not even aware that they have an OWTS, let alone have any knowledge about how the system operates. Proper maintenance and education can prevent premature failure of OWTS, and routine inspections can identify problems prior to complete failure. If problems are detected early, they may be corrected less expensively (than replacement of an absorption area) and also prevent nuisance conditions and disease transmission. Consequently, we recommend that a Responsible Management Entity (RME) i.e. district or homeowner's association provide for inspections, monitoring, and maintenance of OWTS.

Country Club Ranchettes Resubmittal October 4, 2019 Page 3 of 3

Abandoned Oil and Gas Facilities Inadvertent spills at oil and gas operation sites are possible, resulting in soil and groundwater contamination. Additionally, abandoned oil and gas wells and flowlines have the potential to leak oil and gas, contaminate soils and groundwater, and can pose an explosion risk. An abandoned oil and gas well is noted on the subject property. To help ensure residents are not exposed to harmful contaminants, TCHD recommends the applicant conduct an Environmental Site Assessment to better determine the environmental condition of the property. Moreover, the applicant should identify the location of flowlines and ensure they have been properly abandoned. Please feel free to contact me at 720-200-1585 or [email protected] if you have any questions. Sincerely,

Annemarie Heinrich, MPH/MURP Land Use and Built Environment Specialist cc: Sheila Lynch, Monte Deatrich, Michael Weakley, Warren Brown, TCHD
