Dear Willy and Commissioners, This submittal has been prepared to describe the proposed "Subdivision Agreement" of the Anglo Saxon Placer, Anglo Saxon #1, Anglo Saxon #2, Anglo Saxon #3, Anglo Saxon #4, Anglo Saxon #5, Anglo Saxon #7, Monarch, Freya, Midnight Sun, Ruby, and Transvaal claims which are owned by Lloyd and Esther Swartz which are located along Cement Creek, straddling County Road 110. The applicants plan to take these 12 adjoining claims and relocate 10 of the 12 parcels to safer, more suitable 4-5 acre build sites lower in elevation. There are 12 Anglo Saxon claims of which 11 are part of this subdivision. 1 of the 12 claim, Anglo Saxon #4, remains as a whole claim and will be sold as a whole claim. All claims above Anglo Saxon # 4 will be claimed as Green Space that includes: Anglo Saxon # 3, Anglo Saxon #5, Anglo Saxon #7, Monarch, Freya, Midnight Sin, Ruby, and Transvaal. 10 of the Lots lie on 50 acres of the Anglo-Saxon Placer and Anglo Saxon #2, 1 remains part of Anglo Saxon #1. We carved out green space for the EPA in their management of the Anglo-Saxon Tunnel as well. The project is considered a Subdivision Agreement". As this property includes a contiguous 148 acres and we are only using approximately 70 acres, the remainder will be left non-developable as "green space" and open to the general public. While a simple, boundary adjustment was considered as we are not adding any new, additional parcels below 5 acres, it was deemed too complex to move SO many parcels down the mountain rather than the typical moving of boundaries from adjacent claim to adjacent claim This proposed subdivision agreement assures all parcels have safe, accessible sites to recreate or build on should any future owners decide to that are not problematic or violate San Juan County planning guidelines. We have laid out specific building envelopes to assure this, and we have carefully evaluated each, new adjusted Parcel boundary for potential spots that meet such criteria as view shed, geological hazards and SO on. We have also prepared a cumulative impact report in compliance with San Juan County Mountain Subdivision regulations. The proposal complies with Master Plan Goals for the CR110 Corridor. This application is for a Land Use Permit and Subdivision. The applicants are required to obtain a County Land Use Permit because they plan to remove dead trees construct roads, and improve existing roads, removing trees as necessary, as well as subdivide parcels. This application is also for a bridge to be laid across cement creek to service new parcels, existing cabin and San Miguel Power Lines. Upon approval oft the "Subdivision Agreement" the project surveyors will file a new survey plat depicting the interior new property boundary lines at the courthouse. Corners of adjusted parcels will be properly pinned. Additionally, road and driveway work as well as forest management will begin immediately before snow precludes further work in 2025. We are submitting 14 copies of this submittal booklet to Willy Tookey, and one copy directly to County Road and Bridge Supervisor Rusty Melcher. The applicants request review of this project by the Planning commission on February 18, 2025. Thank you for the opportunity to present this information to the San Juan Planning commission and Board of County Commissioners and helping to make our dream of retiring in San Juan County come true. Please contact Lloyd Swartz if you have any questions.

County, Township 42 North, Range 7 West in Sections 66, 67 and 36. Elevation: Subject property varies from 10,000' to 11,200'. Development Permit work is all below 11,000' Overview and History of Project. The applicants to this land use permit are preparing to build a full-time residence within 2 years at Ravens Nest 2.5 miles south of Silverton on Highway 550 on the Prince Edward Claim. This was a part of a similar project completed in 2019 - 2020 where we adjusted 8 claim boundaries and connected roads and access resolving several community concerns. After successfully finding others to purchase the 7 other claims, we decided to keep an eye out for other quality properties in San Juan County that could be developed similarly. In October 2022, we purchased the Anglo Saxon and Transvaal properties. Lying along County Road 110 they provide exceptional potential build sites with year around plowed road access. The prior owner had plans for large scale development that he never completed. We purchased the property with the intention of establishing 12 potentially year around home sites in a responsible manner. By planning practical development on these 12 claims; We are able to limit the construction of new, future access roads. We are establishing permanent access and defined work area for the Anglo Saxon mine cleanup work. We are able to have a single Land Use Permit to establish roads and make practical adjustments to boundaries instead of potentially 12, saving local government time and resources. All properties will have access sufficient for recreational use, forest management and planning for future owners, with safe, permitted building envelops. We were able to design well thought out roads and driveway access to each parcel at once, minimizing impacts to the wilderness, historical structures and view sheds. Establish rare, YEAR AROUND accessible properties that are more financially beneficial to the community then back country properties that are in-accessible for 6n months or more of the year. Preserve 50% of the land through a Conservation Easement or Green Space, protecting prime back country recreation and Wildlife Habitats. Provide easements for neighboring property owner': S needs. Provide year around, heavy duty bridge access for sites across Cement Creek as well as the existing cabin on an adjoining parcel, including fire and rescue. Provide additional access for San Miguel Power Line Maintenance. Protect Significant Fen Emerging and High-Altitude wetlands via use of Green Space and subdividing lower portions of the Parcel to protect those areas. 50 Acres of prime, county road lined property would never have been developed as one or 2 build sites. We believe our plan is the least impactful of any potential proposals, and stops short of a higher density subdivision proposal. Overall Community Benefits: Since our first project much has changed in San Juan County. Silverton has been "discovered", I as well as ski area expansions are in the works. These changes have led to a need for all types of housing, including safe, buildable lots with access. These 12 parcels are location in a prime location between the town and the Silverton Mountain Ski area with extensive, ongoing development with in this designated economic development corridor. And given the vast amount of public lands in San Juan County, mixed with geological hazards viable potential parcels for residences are in demand. By granting approval for this basic subdivision the local community also secures over 50% of this project acreage in its current state, preserving view sheds, habitat and recreation areas. Existing roads will continue to be kept open to the public Applicants are seasoned back country, off-grid, mountain residents who have lived in the high country of New Mexico and Colorado most of their lives. With hands on experience in another back country development in San Juan County and New Mexico they are quite adept in overcoming challenges and taking care of the land. Applicants are planning for long term water improvement projects with the EPA and providing access and parking to other land owners and community members. Carving this area out as Green Space provides for development of 12 parcels without the having to broach the EPA access and development issue each time a permit is applied for. The EPA is considering this as a potential National Model! Quite possibly, the most important benefit to this project is the future potential for 12 new tax paying homes in San Juan County that is YEAR. AROUND ACCESSIBLE. That cannot be emphasized enough as most other back country locations are simply resulting in homes with roads that are not plowed and may never be feasible to plow or access by any means in the winter. This means, these homes are only occupied a few weeks or months of the year. And the Demand is HIGH! We have been contacted regularly by interested parties who wish to build year around residences to work and live in San Juan County since purchasing and proposing this project, including referrals from various Silverton residents. Unfortunately, many parcels and lots are priced outrageously high in the county, and ours will be priced below others to be more obtainable. Proposed Development: Rather than a large-scale development or spread-out development over ever increasingly high mountain parcels with challenging access we propose to create a subdivision with 11 of 12 claims SO that we can establish 4-5-acre parcels in the lower, safer, year around road accessible areas. Proposed Subdivision will NOT increase the number of DEVELOPABLE parcels. There are currently 12, and there will be 12 after re-platting. Driveway and community road improvements would begin August of 2024. An access bridge is proposed and will require building permit, but does not need a foundation. Reasoning for swapping 12 claims for 12 buildable valley parcels: Boundary adjustments are being made in order to; Simply put 50 acres of prime, valley flat land along a plowed county road WILL BE developed. Our proposal is the least impactful way. Adjusting the highest parcels to have lower elevation, potential build sites reduces future planning headaches, preserves view sheds, provides more useful year around accessible home sites, creates significant preservation of pristine acreage and wildlife habitat, limits new roads, creates legal access for all parcels, creates safer build sites, and drops all potential building sites below 11,000'. To generally avoid difficulties between San Juan County Planning Commission and Commissioners with future land owners. Future Improvements: Immediate plans include improving and grading as needed, the existing network of old mine roads across these parcels as well as installing 2 sections of new road to connect the existing road network on the Anglo-Saxon Placer North to the South End, including a heavy traffic rated bridge. Roads across claims will be filed as ROW's for future owners, and current cabin owner. Approximately 1,200 feet of new road will be created in 2 locations. Approximately 1700' of existing road will be improved, regraded as needed. Road section to Anglo Saxon mine tunnel will remain abandoned or no longer maintained unless the EPA elects to utilize it. A future road by others will improve EPA access, not a part of this application. The standard for all new roads is to be passable for a heavy, straight truck to assist in potential future home construction, as well as allow for emergency vehicle access to all properties. Bridge will be rated for over 80,000 Ibs. Road alignments are laid out as to be screened from view from County Road 110 as much as feasible. An Easement will be granted for the owners of the Prodigal Son to access their existing trail without crossing through the EPA site. Permit will be applied for separately by them. See survey. An Easement has been granted for the Aire Lodge for safe, winter time parking. (Approved already by the County) A significant, ongoing effort will be made to remove dead and dying trees resulting from over growth of the forest and past beetle infestation across the property. Mandatory participation or sharing of cost in ROW road maintenance will be included in deeds of sold parcels in the future to insure safe, continuously maintained ROW roads. Zoning: Mountain Mining District: Animas Septic Service: At this time, there are no proposed septic systems. In the future, septic systems for individuals will be required to be designed according to San Juan Basin Health Department (SJBH) specifications by a Colorado licensed engineer. As required by SJBH, the septic systems will be designed in accordance site specific per rate for the number of bedrooms. It is anticipated that SJBH will require the Septic to be engineered. See Attachment M from Septic Engineer Access: There will be numerous access points. Access points were walked with former Road Supervisor, Louis Girodo in May of 2023. These include; New Road to bridge from CR 110 on East Side connecting to existing road near existing cabin. Existing Road on West Side to Parcels from CR 110 Existing Road on North East End to complete loop through Placer Claim Existing Road across bench from County Road 21 See survey for exact locations Access to CR 21 which is currently maintained by the county will remain open until the end for public use to the conservation easements. Access onto the Anglo Saxon Placer via the new road may be restricted to private community and official use in the future. Water Service: No improvements related to water are proposed at this time. Significant surface water rights for these parcels do exist, however as these are being sold as large, individual parcels it should not be required. There are indications the Bonita Peak Basin is less consistent in this area and sources of clean water including springs, appear throughout the property. See attachment M from Engineer See attachment S Water Rights Decree Electrical Service: Power is available all along the property line on the Anglo Saxon Placer for future owners to tie into. Cable and Phone is available on the opposite side of the road to tie into as well. See Attachment T San Miguel Power Will Serve Letter Historic Structures: There are no historic structures of significance on the property, except the Cribbing wall in front of the Anglo Saxon. In the Monsoons of 2024 the wall collapsed and we are collaborating on a suitable fix. Tree Clearing: The extensive, existing road network will see VERY minimal tree removal focused primarily on dead trees that regularly fall across roads and some trees that have grown up close to the roads over the years narrowing the roads too far in places. Trees will be cleared as needed to establish approximately 1,200' of new road across the claims. Road locations have been selected to minimize tree removal whenever possible. Only one section of approximately 80 feet will see any significant tree removal! Owner prefer to stock pile logs for firewood use and chip and spread small debris as opposed to dangerous burning. Tree removal estimates count any trees over 2" in diameter. In some places there is a huge over growth of small trees that inflates the numbers. Road lay out took in to account wetland, road functionality as well as minimizing large tree removal. Some areas are very shady and wet and create a ripe habitat for overly dense tree growth. See Attachment Q for Locations and Estimate Tree Removal Quantities Surveying: There are no modern, complete surveys of these parcels and Southwest Land Surveying is surveying all parcels, pinning corners of adjusted parcels, laying out the EPA parcel, new and existing roads, and easements for other property owners. A preliminary survey with over lays is included in this application, with final work to take place after approval. After county approval of this proposed Boundary agreement the County/ Project Surveyor Dirk Hatter will be submitting a new Survey Plat to file at the County Court House. Subsurface and Geo Hazard Conditions: Subject mining claims lie on Ohio Peak and along the Cement Creek Valley. There are no known landslide, snow, or rock slide areas that threaten likely build sites. Attachment A shows snow slide relationships to parcels. The County Geological Hazards Map Indicates the subject property is CST or colluvial slope accumulated areas from Colluvium or Glacial Sources. This can indicate potential land slide issues, however as is typical this map is not very reliable as it paints broad brush strokes over huge areas. In person observation is important as well as more detailed analyses when a build site is proposed. (Not a part of this application except for bridge) Actual observations for the purposes of potential build sites in project area indicate more of a shallow, bedrock underlying base on the West side of 110 including the bench. In some areas CST is quite accurate for the hills East of the property line, but that is outside the scope of this proposal and potential build sites on relatively flat ground without the ability to slide. The site was visited by a Licensed Geotechnical Engineer. The only significant issue is a historic land slide on lot 6 that ends before lot 8. While it does not threaten a build site, steering clear of this hill for building a cabin is a good idea, and the building envelope reflects this. See Attachment K. Troutner Geotechnical Report Anglo Saxon Mine This property contains the Anglo Saxon Mine. This previously inventoried Bonita Drainage Mine has had work as recently completed in 2023 to re-direct run off to naturally existing settling ponds, and away from Porcupine Creek and Mine tailings. At this time there is no "final decision on remediation", / however it is unlikely much more work will happen. I met with Athena Jones, Mark Rudolph and others on site. And discussed the current situation and what should happen moving forward. The EPA would like to repair the cribbing wall in the future that presents a hazard for CR 110, and continue to occasionally dredge the ponds every 5 years or SO from the road. Additionally; We discussed keeping all development a reasonable distance away, and mapped out comfortable perimeters taking many possibilities into consideration. (i.e.: Test holes, future access needs etc.) Re-locating the prior planned easement (by prior owner) for The Prodigal Son which was completed. And we laid out a perimeter which was later surveyed to isolate the Anglo Saxon mine from the other claims, reducing future administrative work loads and isolating the property as a single point of contact and ownership. This could be a model to be used moving forward on other projects. This will be maintained as Green Space. Based upon these discussions and commitments they would write a clearance letter in support of this project since there is currently a hold on this property due to the un-completed reclamation. Letter to be issued after application for permit is submitted. See attachment M Liability Release and Access letter for EPA Wildfire Analyses: Wildfire is a serious concern in any wildlands interface, with the problem of wildfire growing for numerous reasons. However, at the generally high elevation and wet nature of San Juan County combined with regular tree less fire breaks leads to limited, and small acreage fires, primarily as a result of lightening. As a contrast to dangerous conditions in nearby La Plata county. Writer of this proposal and specifications did not have access to planning department excepted wildfire analyses publications. However, as of 2017 the Colorado State Forest service utilizes an updated portal that is extremely detailed. The subject property falls into moderate to high risk factor categories. Taking a close up look at the property, you have Grassy Gulch, Cement Creek and County Road 110 as fire breaks. Access to creek water and nearby storage ponds is available. The San Juan County fire department is 3.6 miles via State Highway to subject property, SO fire protection and response is adequate. Access roads will be un-paved but accessible to any vehicle. A bridge rated to handle fire trucks is including in this proposal. Dead trees and pine beetle damage are relatively low in this area, and efforts to remove dead trees during development as well as clear ladder fuels will be made. A secondary escape route across the creek from the East side of the Saxon Placer will be re-graded and maintained for emergencies. Other road distances to county road 110 are relatively short. Additionally open meadows could provide for safe zones in a fire emergency. Off Country Road 21 build sites can access the road in 2 directions, providing an alternative means of egress. The following pre-cautions will be utilized in construction for future building permit requests; Create fire breaks around homes. Utilize fire resistant home construction including Logs which are of the highest fire rating and metal roofing. Thin property and remove excessive dead trees. Create firebreak roads on property with fire protection access. Maintain defensible zones for future structures. Utilize removed trees for firewood. Utilize "smart" remote monitoring fire detectors. Maintain access to lower emergency egress route via power line road. Maintain a water wagon in the community for small fires to prevent them from becoming big problems. * Note: Note Fire Map is not attached as it's not very useful Avalanche Hazard: San Juan County has a rich history of avalanche danger, not to be taken lightly when planning a residence, with 2019 demonstrating just how powerful they can be in particular. In the case of the subject mining claims; Several of the proposed adjusted parcels do overlap The Grassy Gulch Slide #43 Pages 225-226 of the Atlas. (also see our overlay) As well as small runs on the Anglo Saxon Mine Side that either do not exist in reality, or are of much smaller coverage then the map shows. However in no instance do they come close to potential, flat build sites. The Grassy Gulch slide relatively minor avalanche run is relatively skinny and parcels have buildable sites far outside of this slide path. An existing cabin has existed for decades in a blue zone right near the outlet of this path with no issues. Discussions with an avalanche expert indicated this run is well mapped and no further study is required. The exception would be if a future permit applicants selected a build site in a Blue Zone type area in which case San Juan County may have to require a study for that specific application. Under this proposal we do not select as exact build sites and further confirmation of hazards would be up to future owners. The only other mapped slide path on the property is Porcupine Gulch map 47, pages 178-179 of the Atlas. This path runs out over the Anglo Saxon mine site and is not likely relevant to any future parcel build sites. There is NO significant indication of avalanche with in the last 100 plus years in this run. See attachment A: Avalanche See attachment B: Geo Hazard View Shed: In some areas of San Juan County view shed impacts can have a negative effect on the environment for visitors. These parcels were partially chosen because and future construction could be easily screened. Overall building locations are well screened by trees and away from any customarily visited locations to be seen without some effort and should any future buildings be viewed; the type of construction may be dictated by the San Juan County planning commission at the time of building application permit submission. Potential view point locations analyzed for these parcels; County Road 110 - See attached photos of selected potential build sites for reference. The 5 Parcels West of 110 have a nearly 0 percent chance of being visible. Potentials spots on the East Side will vary from slightly visible to nearly impossible. From Existing Cabin = Trees provide excellent screening for all parcels and it is difficult to view the existing cabin from most places on our parcels. Ridgelines = Potential building envelopes may more closely be reviewed at the time building permits are submitted. However easy set back from any ridgeline edge is possible. See attachment C Access Photos See attachment D Lot/ Parcel Photos * While we have generally located, safe, approvable building envelopes outside of hazards and view shed conflicts with access. These are merely suggestions and are subject to final approval by San Juan County upon submission of a building permit request by a parcel owner and may be adjusted for appropriateness at that time. Wetlands: As the Placer claim has Cement Creek Running through it and we must cross the creek we engaged the services of SME Engineering to evaluate the entire Placer Claim where roads will run. Their inventory and map is attached. The new Bridge Crossing of Cement Creek will NOT impact a wetland as both sides are not wetlands and this will be a clear span. However, while no traditional wetland issues were un-covered, there are some Fens on the property. As a result, new roads were re-surveyed and re-laid out several times to make sure no Fens OR traditional wetlands would be disturbed. The hard work applied to this process has resulted in a more environmentally friendly road lay out. We managed to reduce impacts to a whopping .03 of pre-emergent wetlands, primarily rocky soils with some wetland type plants. No other important habitats were inventoried. One additional parcel was re-structured to make sure quality potential build sites exist outside of the Fen areas which will remain open between parcels for wild life or potentially horses. Initially an Army Corps of Engineers 401 permit was applied for, but rejected in favor of a basic Nationwide Permit due to lack of impacts. Nationwide Permit Verification (SPA-2023- 00492) this permit requires no other action other than to minimize impacts as proposed, and stay away from mapped Fens. Soil samples were taken for confirmation. See attachment E SME Aquatic Survey See attachment F Army Corps Nationwide Permit Bridge: As the only current access to the North Side of the property is via driving across Cement Creek. A single lane, beam and timber bridge has been designed by E & H manufacturing to provide access across the river for parcel owners, the existing, neighboring cabin, construction and emergency services as well as power line maintenance. This is a Basic Timber bridge that blends well with the environment. See attached design and engineering from E &H Manufacturing. This bridge system utilizes 2 40' sections of pressure treated and tensioned timbers between steel beams. No footings are required, hence no wetland disturbance or flood issues. A Geo Test was undertaken to assure adequate soils and is attached. A Colorado engineering firm was contacted but since there is no concrete foundation the manufactures plans may be utilized. Think of it like the many rail car bridges in the county, only this one is engineered! A few key points on this system: Design Meets HS 20-44 standards or 80,000 Ib. 40 ton capacity. An optional drainage gravel will be utilized. Bridge may not exceed 2% slope 5' Overlap on land of bridge ends is mandatory and painted onto bridge sections. Owner will assist in yearly inspections of hardware and welds Tensioning of compression bolts must be checked every 10-15 years Owner has constructed much larger bridges in the wilderness prior. Bridge is well above the FEMA Flood Plane See attachment G Bridge Engineers drawings See attachment H Bridge Flyer See attachment I FEMA Flood Map Overlay See attachment J Bridge Survey See attachment K Geo Tech Report Road Construction Standards: SWPPP Plan = As we will not be disturbing an acre or more a formal Storm Water Permit Plan is not required. However, great care will be taken to minimize impacts to Cement Creek during bridge construction, as well as any other negative run offs of silt. Road Base - To every extent possible road will be constructed using native materials. Areas that are muddy will be rocked in and gravel or base course topping added as needed. In our experience rocking muddy areas to prevent stuck vehicles or sediment run off is the number one issue. Primarily on-site cobbles and native fill that needs cleaned up from the Airy Lodge project will be utilized. Culverts = None anticipated, but could be added for minor, seasonal drainages. Plastic culverts to be used if highly acidic run off is encountered. Bridge Engineered as a single lane steel beam and timber bridge that will hold heavy duty traffic including construction equipment and fire trucks. Width - Minimum of 12 feet single lane. Turns wide enough for large, straight trucks. Current road requirements call for a 24' 2 lane road, which would cause unnecessary impacts to service a handful of homes. This is yet another case of a requirement based upon an in-town subdivision. We would prefer to stay between 12'-16' as is typical in the back country. The average width of Country Road 61 is under 15'! Geotechnical - Soil tests conducted for Bridge Abutments Retaining Walls 4' or greater - None Anticipated, however approximately 4 feet of native fill will be used at the CR 110 connection. This connection will maintain appropriate slope and will not interfere with the count road in any way. A Colorado stamped and engineered design for Keystone is available if needed, up to 7' high (would require Geo Grid inspections). Road Grades No roads will created with more than 8% Grade. Most sections are relatively flat. The driveway entrance off Highway 550 will be approximately 6% and the steepest grade encountered. Flood Risk Analyses: While FEMA Flood Risk Maps do include Cement Creek, a few points should be made; These maps are typically a bit exaggerated as grades were not shot in on site. The Majority of the flood zone is essentially the creek bed. Cement Creek does not have a history of major floods. All FEMA zones are 100 year. Expanded areas shown on maps are all cobble bars with one exception Proposed bridge location is FAR higher than the 100 year flood zone at that location. All parcels have approval build sites outside of the mapped flood zone. Observations were made during 2023 peak run off, and never did the creek significantly enter even the cobble bar 100-year flood zones. See attachment I FEMA Flood Map Overlay HOA A limited HOA will be required to be established once year around habitation of property begins to primarily insure residents work together on road maintenance and snow removal. See attachment P sample HOA Guidelines Snow Removal I was asked to discuss snow removal and stowage considerations. With small lot, in town formal subdivisions snow storage can be a significant issue. But we are working with 12 parcels or potential build sites on approximately 70 acres, with 4-5 acre build sites. Because of this there is nearly unlimited room to remove snow or create snow piles. A Solar Shade analyses was completed based upon 11:00AM and 3:00PM in December, and no lots or roads are shaded during that time. Areas shown as no light are not part of this project. See attachment U- Solar Shade Analyses Lot/ Parcel Layout Deviation Willy Tookey pointed out that many lots are divided by roads. While we have created many revisions to our proposed plat, we are attempting to keep within 3 conditions; 1. Lots of 4 acres or more 2. Keeping 12 mining claims for 12 buildable lots and not adding more. 3. Avoid building sites that are hazardous, avoiding Fens and Emerging Wetlands, difficult to access places, or likely to see building permit rejected at a later date. With these constraints, it's simply not possible to exclude a road crossing a parcel. Again, this is different than a large scale, in city subdivision where you plop a street down the middle and have lots on either side of very small size. Many lots would have to be divided into smaller than 4 acre parcels, both triggering impractical subdivision development requirements as well as a density that owners and County citizens do not want to see with in the back country. Affordable Housing Requirement This is yet another requirement that makes no practical sense for a mountain subdivision. Custom homes are typically more expensive to build in the back country due to installing Septic and Water, as well as other conditions. Nor are we building any homes. While we could argue some lots will be priced less than the others, and call it "affordable housing"I feel it's a bit disingenuous. Some sort of negotiated, reasonable contribution towards affordable housing efforts in a more practical location in town could be an option. As communities in Colorado come to grips with affordable housing issues, one fact remains across the research spectrum, and that is less housing equals bigger problems. Restricting responsible development of any kind drives up prices in a supply and demand economy. San Juan County needs all the housing and buildable lots that can be found to provide for housing needs of all types. BOARD OF COUNTY COMMISSIONERS San Juan County P.O.

A description of the site assessment methodology is provided, followed by a discussion of the regional, local and site-specific geology. 2.1 Scope of Assessment We performed a geologic field reconnaissance of the site on August 30, 2024. The geologic reconnaissance included detailed observations of the site to evaluate the existence and potential significance of geologic hazards that may: influence the proposed development. The general scope of our study included the following: Literature and map review of the site. Geologic field observations and measurements including a description of the site topography, geologic character and geomorphology. Identification and analysis of geologic hazards that may influence the project development and proposed lot layout. This study focused on the following geologic hazards (these are the hazards defined by HB 1041): Avalanche; an evaluation and discussion of the site exposure to avalanche hazards. 3 TRAUTNERJEROIEAETTA Project No. 58075GE October 24. 2024 Landslides: identification of landslides in the site vicinity includmng recommendations for analysis of these features if they exist in areas that will influence the proposed development. Rockfall observations ofpotential rockfall source areas and: identification of areas which may be influenced by rockfall. Computer modeling analysis was performed to quantify hazard potential. Expansive soil and rock; an evaluation ofthe potential for expansive soil and rock was performed based solely on surface observations. A geotechnical engineering study 1S required to evaluate the extent of the sité expansive soil conditions. Mudflow and debris fans: identification of areas of the site which may be influenced by debris flow activity. Unstable and potentially unstable slopes; identification of potentially unstable and unstable slope areas based on our geologic field reconnaissance and available maps. This 1S also based 011 surface observations and 1S more completely analyzed as part of a geotechnical engineering study. Radioactivity: literature review regarding the potential for hazards associated with radiation Seismic effects; identification of local faults ànd recent activity based on the available literature and field observations. Ground subsidence identification of subsidencé prone areas and récent activity based on the available literature and field observations. A discussion ofthe hazards as they pertam to the project 15 included m Section 105 ofthisreport 2:2 Geologic Observations We have provided al brief discussion oft the regional and local géology followed by a more specific discussion of the site geology below to provide background information prior to discussing the site-specific geologic hazard considerations. 2.2.1 Regional Geology Discussion The site 15 located in the San Juan Mountains of southwestem Colorado. There are diverse geologic conditions in the area, all of which may have an influence on geologic hazard considerations and land use. Geologicrock units in the region range from Pre-Cambrian Granite and Gneiss to late Cretaceous to early Tertiary sedimentary shale and sandstone units. Middle to late tertiary volcanic units are common in the Alpine regions ofthe area. Later quaternary glacial, eolian soils and soil deposits produced by weathering overly the rock uits are common. The shale and sandstone rock units and associated soils produced from weathering of these materials are commonly encountered in developed areas. Dunng the middle to late Cretaceous approximately 80 to 66 million years ago a mountain building episode termed the Laramide Orogeny" caused regional uplift oft the area The San Juan Dome was formed, the erosional remnant of which exists. under the mountamous areas 1n the region The San Juan Basin which has since filled with sediment was formed in the area south of 4 TRAUTNER ETA Project No. 58075GE October 24, 2024 the San Juan Mountains This activity caused upwarping and deformation oft the geologic units in the area. This uplift is evidenced nearly everywhere in the region. The sedimentary unit bedding planes all dip (tilt) generally toward the south, and the center oft the San Juan Basin. The numerous hogback ridges and cuestas in the area are formed by steeply dipping sedimentary units. There have been several glacial episodes which have occurred m the area. Glacial morame and outwash terrace deposits are common in the area. The U-shaped valleys in the region are a testament to the erosional forces imposed by the glaciers. 2.2.2 Local and Site Geology Discussion The project area 1S bisected by Cement Creek which 1s a generally north-south trending valley. The Cement Creek valley and various smaller side drainage features are covered by Quatemary aged deposits of alluvium (Qal), glacial drift (Qd), alluvial cone (Qac) and landslide (Qs). These areas were once covered by Palezoic and Mesozoic sedimentary rocks that were removed by erosional forces during the Laramide Orogeny betwéen 70 and 40 million years ago. The erosional surface was then covered by Tertiary aged volcanic rocks then Quatemary aged sediments. The bedrock unit that lies beneath the site 1s the Burns Member (Tsb) volcanic unit. The slopes in the vicinity are generally covered with a relatively thin mantle of colluvial material. The area was extensively glaciated during the Pleistocene: resulting in the peaks and ridges and U-shaped valleys seen today (Luedke and Burbank, 2000). A portion of the Geologic Map of the Silverton and Howardsville quadrangles, southwestern Colorado 1S provided below for reference. hc pd Approximate Site Pach Property Location 9t9 ad Figure 2.1: Luedke, RG., and Burbank, W.S., 2000. Geologic Map of the Silverton and Howardsville quadrangles, southwestem Colorado. Geologic Investigations Series Map I-2681. Map Scale 1:24,000. Volcanic bedrock was observed exposed in the road cut on the west side of the site; however, the majority of the project site appears to be covered with some thickness of alluvium and colluvium. The project area on the west side of the Highway 110 is bound by Porcupine Gulch to the north and Ohio Gulch to the south. On the east side of the Highway, Grassy Gulch cuts through the north end oft the project area. Illinois Gulch is located south oft the project area. The south end of the project area is bounded by a large mapped landslide complex (Qs). This landslide complex 5 TRAUTNER EOECHC Project No. 58075GE October 24. 2024 encompasses the southem énd ofLot 5 on the proposed development plans as discussed below. 3.0 GEOLOGIC HAZARD DISCUSSION This geologic hazard study presents our interpretation oft the surface characteristics and geologic exposures at the project site. Our hazard assessment is based on our surface observations, a review of available literature, geologic mapping for the area, and on out experience in the area. As discussed lin the scope ofservice section above, we investigated for evidence that the following géologic hazards may influence the proposed project development; Avalanches Landslides Rockfall Expansive Soil and Rock Mudflows and Debris Fans Unstable or Potentially Unstable Slopes Radioactivity Seismic Effects Ground Subsidence We have provided a bnef discussion of the potential hazards, followed by the observed and predicted conditions. 3.1 Avalanches Avalanches typically occur on slopes between 30 and 45 degrees m gradient where there IS enough snow to cover low-lying vegetation. Avalanche paths generally consist of three parts: the starting zone; where avalanches initiate, the track: where avalanches reach maximum velocity, and the runout zone, where avalanches decelerate and deposit snow and debris. Avalanche paths can be unconfined, channelized, or a combination ofboth In Colorado many avalanche paths are confined by gullies and with the limits ofregular/recent activity being defined by the forested areas adjacent to the path. Trautrier Geotech does not provide detailed avalanche studies or mitigation recommendations. Wel have provided the information above to aid the reader in a general understanding of avalanche hazards. Our commentary below is based our general geologic hazard experience and on our review of literature that is locally available in regard to avalanche hazards. Slopes above the project development area exceed 30 degrees; however, the site is genérally heavily treed in steeper areas and no evidence of avalanche activity except for the Grassy Gulch avalanche path The Grassy Gulch avalanche path 1S mapped in the Avalanche Atlas, San Juan County, Colorado (Miller and others, 1976). The Grassy Gulch path is listed at Path Reference No. 157043 m the study. This path consists of an approximate 2,000 vertical foot and 4,600 linear 6 TRAUTNER TE Project No. 58075GE October 24, 2024 foot long path with a runout zone that cuts across Lot 9 and possibly into Lot 8. However, the building envelope for Lot 9 is roughly 200: feet north and roughly 40 foot vertically above the slide path. The building envelope for Lot 8 is roughly 500 feet south of the slide path A schematic from the referenced. Avalanche Atlas showing the Grassy Gulch slide path is provided below. We have also provided an aerial image showing the approximate building envelopes. 043 Figure 3.1: Schematic showing the Grassy Gulch slide path. Adapted from Avalanche Atlas, San Juan County, Colorado (Miller and others, 1976). 7 TRAUTNERJBSOEHETTA Project No. 58075GE October 24, 2024 pors kmate.Lorg - EinoEnvéope Approximate Slide Path Approsimate Lor 8 Bulcing Enveiope Figure 3.2: Schematic showing approximate relation ofLot 8 and 91 Building Envelopes to Grassy Gulch slide path. Location of slide path should be considered approximate and is based on interpretation of Avalanche Atlas drawing. Itis our opinion that avalanche 1S not a significant risk of development oft the project site building envelopes; however, access to the proposed building sites will cross avalanche hazard areas. Ifthe owner 1S concerned about avalanche risk at the project site, we recommend that an avalanche consultant be contacted if detailed information is desired for this project site. 3.2 Landslides "Landslide" 1S a term to describe active slope movement. It is often used in a broad sense to describe any unstable slope or soil movement. A generalized depiction of a typical landslide is shown below. 8 TRAUTNERAEOIEAETTA Project No. 58075GE October 24. 2024 Crown and Sloped Ground Surface Crown Fractures Lateral, or Edge, Scarp Secondary Scarps Head Scary Longitudinal Fissures Head Toe Primary. Surfacelof failure Transverse fissures Basic Components of a Landslide Landslides may be relatively small slumps of may be largèr scale slope failures. Mitigation of active landslides is often difficult and always costly. Evaluation of active landslide areas must include detailed subsurface investigation, laboratory analysis ofthé soils and detailed engineering analysis'çomputer modeling as the basis for mitigation design The subsurface investigation typically includes placement of monitor well (piezometers) and often inclinometers at select locations on the project site. We performed a site reconnaissance of the project area to identify potential mass movements within or adjacent to the project area and performed observations of the proposed building sites The proposed building envelope on Lot 1i is on a relatively steep slope with existing slopes ranging from approximately 20 to 40 degrees. Additional analysis for Lot 1 is provided below in Section 3.6. The southem end of the project area on the east side of Cement Creek was found to show evidence of slope movement. This may be related to the large-scale mapped landslide noted on the Geologic Map of the Silverton and Howardsville Quadrangle No recent slumps or scarp features were observed; however, evidence ofs slope creep was observed inj pistol-butted trees along the slope. This study does not include detailed analysis of the global stability of this feature; however, for planning purposes we do not recommend any excavation into or near the slopes on the site without a detailed slope stability analyses. In lieu of detailed analysis, all building envelopes should be located outside ofsteeply sloping areas, particularly on Lots 5 and 81 based on current schematic development plans. Concentrated or poor drainage resulting m saturated soils conditions could reduce the soil strength over the overburden colluvial debris throughout the development. This could increase the risk of future slope failures in steeper slopes. Additional analysis and recommendations are provided below in the Unstable or Potentially Unstable Slopes section of this report. 9 TRAUTNER EUTEGA Project No. 58075GE October 24. 2024 33 Rockfall Rockfall hazard exists wherever rock has the potential to dislodge and move downhill by forces of gravity. This process 1S usually associated with a weathering of formational material. Freeze- thaw cycles and availability of free water promote rockfall; therefore, spring is the most active season for rockfall. The steep topography and fractured rock outcrops that are common to this region make rockfall à common hazard. Rockfall can occur without waming and can be destructive to both life and property- Rockfall frequency is very difficult to predict, but modeling techniques allow us to estimate the trajectory and intensity of rockfall events. Simulation of rockfall events to provide an analysis of the potential destructive properties are typically performed using field mapping and observations m addition to computer modeling analysis. We did not observe any rockfall hazard areas that likely have the potential to affect the proposed building sites We can provide additional observations and analysis as the project continmes to the design phase. 3.4 Expansive Soil and Rock Uplift associated with swelling soils typically occurs only where the foundation support soils have been exposed to water, therefore, the uplift may impose shear stresses in the foundation system The magnitude ofthe imposed shear stress 15 rélated to the swell pressure of the support soil but is difficult to estimate. We observed exploratory test pits throughout the proposed development The soils encountered in the pits generally consisted ofclayey sand (SC) and clayey grayel (GC) soils TO the depth explored. Based on our preliminary observations. the soils encountered do not likely have high expansive properties; howéver, we récommend detailed geotechnical engineering studies that include subsurface exploration and laboratory testing be performed for all structures planned in the development 3.5 Mud Flows, Debris Flows, Debris Fans and Flood Mud flows and debris flows mitiate in drainage basins duning signifiçant precipitation when large concentrations of sediment become entrained and flow down-slope, often carrying boulders and organic debris within a matrix ofc clay and water. Debris fans are areas where debris flows or mud flows deposit matérial that spreads out in a fan-like shape at the mouth of channels where thé smaller, steeper channels meet larger, low gradient stream valleys. Debris flows and mud flows contain larger concentrations of entrained solids than floods and move with high energy down steep slopes, thus they can be very destrctive. Historically, debris flows are more threatening to property than to life. Debns flows differ from mud flows in that they contain larger matenal (debris) the size and weight of which 15 mostly limited by ayailability and chamnel size, not the abiliry of the flow to transport. Because of this they tend to be more destructive and so debris flows will be the focus ofthis report. Debris flows have return periods similar to floods, and often flooding occurs in conjunction with debns flow events. There are four conditions that must be present within a basin in order for it to be susceptible to debris flow (Mears, 1977). Sufficient loose sediment/debris 10 TRAUTNER E Project No. 58075GE October 24. 2024 Sufficient clay content of sediment Sufficient gradient of the channel and slopes Low ratio ofavailable water to available debris Ifall of these conditions are met, aj precipitation event of sufficient intensity and/or duration can trigger a debris flow. Processes of damming and pooling can serve to increase the likelihood and/or magnitude ofa debris flow event relative to the precipitation event that miggers it. Stream drainage basins that have been demuded of vegétation due to fire are particularly prone to debris flow activity. When present, these conditions combine to facilitate debris flows by increasing viscosity, strength, entrainment, and energy of captured precipitation Otherwise, ifthe conditions are not met, the same precipitation event would instead tngger a flood. Debris flows transport boulders and debris along the upper surfaces of flow (Mears. 1977). This means that the greatest impacts from debris flows occur along this upper surface elevation which can be several feet above ground level, Channelization of debris flows 1S not always a given. particularly at the debris fan below the mouth of the drainage. Debnis flows can vacate a channel byap process known as avulsion, m which a previous debris deposit can block and divert subsequent flow. Debns flows also exhibit confined flow on unconfined surfaces due to sheanng off of matenal from the margins leaving behid lateral levee deposits and thereby creating its own chamel as it flows. These factors dictate that the entirety ofa debris fan surface is susceptible to flow hazards that can exist several feet above the ground. Often developmént and proposed development that is affected by debris flow hazard 1S located on these debris fans. Based on our site reconnaissance, the existing and proposed building sites do nof appear to be located in a debris flow hazard area and no areas currently subject to debris flows were identified with the exception ofGrassy Gulch. However, Grassy Gulch is located outside ofplanned building envelopes. If there is a debris flow potential, access roadways may be affected but structures would lie outside of debris flow potential areas. Given the relatively steep slopes of some ofthe proposed development areas and areas above building envelopes. sheet flows should be anticipâted, especially when the soils have been disturbed The project civil engineèring consultant 1S responsible for development appropriate drainage throughout the development. 3.6 Unstable and Potentially Unstable Slopes As a general standard, any slope with a gradient of 30 degrees or greater 1S considered potentially unstable, although flatter slopes can be potentially unstable depending on the soil characteristics and subsurface water conditions. Any slope that exhibits evidence of prior movement 15 considered unstable. Mechanisms of movement in unstable slopes include falls, topples, slides, spreads, and flows. These mechanisms can all be categorized as other hazards discussed in this report. We previously discussed slides and spreads as "landslides" (Section 3:2), falls and topples as rockfall" (Section 3.3) and flows as "mudflow, debris flow, and debris fans" (Section 3.4). Unstable slope areas may be distinguished from other geologic hazards by the lack of associated definable features: however, the physical procèsses are analogous. As noted m Section 32, Lot5 IS located within a mapped landslide. area and disturbance of the steep slopes adjacent to this landslide complex should be avoided Lot 1 however 1s located on a steep slope. We have provided a limited analysis of the existing stability conditions on Lot 1 below. 11 TRAUTNER HETE Project No. 58075GE October 24. 2024 3.6.1 Lot 1 Limited Slope Stability Analysis This section of the report provides conceptual stability modeling based on our observations of the existing conditions. We obtained measurements of the existing slopes during our field study. This analysis shows existing conditions only and does not model anticipated excavation cuts for futre planned development. A detailed stability analysis should be completed once design plans have been established. The specific design of slope stabilization and shoring structures for the project 1S beyond our scope of services. The following analyses and concepts presented below are limited in nature and are intended to provide general stabilization techniques that are applicable for the subject project. The specific design of the retainig and excavation shorting structures should be performed by a retaining/shoring system specialist: There. are firms local to the area that specialize in the design and construction of these systems. We are available to assist you in selecting competent design professionals for the project. We anticipate that seasonal subsurface water may be present within the slope mass during periods ofs snow melt or penods ofheavy precipitation and included a water table in our analysis. Adequate surface drainage must be constructed in conjunction with the cut/fills to prevent the accumulation of water and hydrostatic pressures. The geometry ofthes slope CrosS section that we analyzed is based on site measurements obtained during our field study. There are numerous methods and techniques available for slope stability analysis Most methods mclude an evaluation of the strength of the soil materials within the slope, anisotropies withm the slope matenals, such as formational matenal bedding planès, and anomalous soil contacts, the subsurface water and soil moisture conditions. and, the pre-construction and post-construction geometry of the slope areas where development and construction are proposed. The data developed during the analysis 15 condensed and used to estimate the forces within a soil mass that tend to drive movement and the forces that tend to resist movement: Theratio ofresisting forces to driving forces 1S often referred to as the "theoretical slope factor ofs safety" (FOS) which is a somewhat misleading term to describe this ratio. The ratio is not a true factor of safety, but 15 a useful mathematical characterization oft the forces within a soil mass and the associated stability condition ofthe slope being analyzed. A: ratio ofless than 1.0 indicates that the dnving forces within a soil mass are greater than thé resisting forces, therefore movement of the slope Is occuming A ratio of 10 indicates that the driving forces are equal to the resisting forces, which indicates that movement within the soil can be triggered by only slight increases in the driving forces or slightreductions in the resisting forces. A fatio of greater than 10 is an indication that the driving forces are less than the resisting forces and the slope 15 not moving Since there are mumerous variables and incongruities within most soil masses, a slope 15 generally not considered as stable iless the ratio 15 about 1.5 Or greater. Generally, slopes or slope/structure combinations with a theoretical factor of safety that is greater 12 TRAUTNER EA Project No. 58075GE October 24, 2024 than 1.5 are considered appropriate for sites where structures are planned. A factor of safety greater than about 1.3 is often considered as being stable for roadways and other inhabitable structures. Aratio of 1.2 is often considered suitable for temporary excavation stability. We used SlideB) slope stability software to evaluate the stability ofcomputer modeled slope CrosS sections of select portions of this site. We primarily used the Modified Bishop' 's Method of slices to analyze the computer modeled slopes. The Modified Bishop' s Method of Slices evaluates the resisting and driving forces within slices of the sloped soil mass along a theoretical semi-circular failure plane. The semicircular failure plane with the lowest theoretical factor of safety is labeled the critical circle. Wel have utilized one basic soil horizon in our analyses below. Subsurface exploration including exploratory borings may be required to perform a more detailed analysis and to determine where the soils-bedrock interface lies. The yellow-colored region represents the colluvial overburden soil material. We estimated an angle of internal friction (phi) of 38 degrees, drained cohesion of 135 pounds per square foot (psf), and soil density of115 pounds per cubic foot. We analyzed the estimated worst case CIOSS section across the project area located (A-A') as shown below on Figure 2. Section (A-A) Figure 3.3. Location ofStability Model Cross Section.

Analysis of proposed cut slopes and specific design of slope stabilization and shoring structures for the project is beyond our scope ofs services. The specific design of any retaining and excavation shoring structures should be performed by a retaining/shoring system specialist/enginer. There are firms local to the area that specialize in the design and construction of these systems. We are available to assist you n selecting competent design professionals for the project. This section of our report provides geotechnical engineering design parameters but does not provide shoring design. The project designer must be contacted to provide a design based on the information presented in this report. Once development plans for the lot, includingproposed cut and fill slopes, a detailed geotechnical and stability analysis should be completed for the site. We are available to review and tailor our récommendations as the project progresses and additional information which may influence our recommendations becomes available. 3.7 Radioactivity (Radon Issues) Many soils and formational matenals m westem Colorado produce radon gas. Radon is a 14 TRAUTNER EUTECHIC Project No. 58075GE October 24. 2024 radioactive gas that fomms from the natural breakdown ofuranmm m soil, rock and watèr. There areno knownsources ofradioactivity on the site, However, according toj the San Juan Basin Public Health Department, the average radon Ievel in Sani Juan County homes exceed 4pCi/L. The Environmental Protection. Agency recommends radon mitigation in homes with levels higher than 4pCi/L Radon tends to accumulate inj poorly ventilated areas below ground level; however, radon may accumulate mside any above- or below-grade construction. According to the EPA, elevated radon levels m buildings can be reduced by several methods, including pressurzation of the building using a heating, ventilating and air-conditioning system, sealing of cracks in foundation walls and floor slabs which mayi allow entry ofradon, and using active soil depressurization (ASD) systems. If radon gas 1s a concem in the completed structures. as specialist mn radon mitigation should be consulted. 3.8 Seismic Effects Seismic effects manifest in the form of earthquakes and volcanic activity: Seismic effects are evidenced in the geologic record by faulting and jointing of formational materials. Earthquakes expenenced by humans 111 recent history have been monitored, recorded, and compiled in databases; locally the "Colorado Geological Survey's Colorado Late Cenozoic Fault, Fold and Earthquake Database" Farthquakes cause damage by ground shaking, surface rupture and other deformation, liquefaction, and Tsunamis. The orogenic history of the region (refer to Section 3) was accompanied with a multitude of seismic effects. Thesè seismic effects have sincé largely subdued. Colorado 15 considered to be outside of the high nsk area ofthe westem US (Nuhfer et al, 1993). The modem seismic environment m the region 1S relatively benign, however not isignificant: Several formdable eyents have been recorded m the Dulce New Mexico area south ofl Pagosa Springs. Mitigation of seismic effects 1S typically included m the struchural design and requirements are based on zoning The most recent earthquake activity in the region of the project site occurred along the Ridgway Fanlt onNovember. 21, 2006 with a magnitude of3.3 on the Richter scale and Modified! Mercalli Intensity of IL The Ridgway fault is defined by a 1,500 foot high fault-line scarp. but there 15 no observable surface rupture in middle to late Quatemary deposits indicating no recent activity that has manifested at the ground surface. Although this fault is considered to be potentially active, the recent activity on the fault, such as the 2006 event mentioned above as well as the November 19, 1989 event with a magnitude of3.0, are low intensity, non-destructive events. Other seismic activity m the region occurred m Ouray, Colorado on November 22, 1989 with a magnitude of2.9 on the Richter scale, and in the Telluride vicinty m 1894. Based on newspaper accounts from this time 1t was. rated as. IV on the Modified Mercalli Scale. This information was obtamed from the Colorado Geologic Survey, Earthquake and Late Cenozoic Map Server. Although seismic activity has occurred m recent history. the low magnitude and lack rofproximity to plate boundaries indicate that there is a low hazard related to seismicity at the project site. Due to the low seismic effect hazard at this site we do not feel that mitigation practices outside of that which 15 required by building codes is necessary 15 TRAUTNER T Project No. 53075GE October 24. 2024 3.9 Ground Subsidence Ground subsidence is the process by which ground level rapidly drops. This drop is often related to an undermining ofthe material present at the surface but may also occur from tectonic processes and hydrocompaction (a process related to increased water content of soils). Undermining of matenal is caused by solubility, karst topography, fluid withdrawal, and mining Subsidenice due to undermining is often termed a "sinkhole". descriptive of the manifestation of the subsidence at the surface as the once overlying matenal collapses into a void beneath. Mined localities are particularly susceptible to ground subsidence because of the unnatural state in which they, are fashioned (Coduto. 1999). Mine sites mn the region likely present the highest rsk areas for ground subsidence. No known mine adits of subsidence prone materials exist at or under the project site. There 15 no evidence of ground subsidence at the project site. Therefore, it 15 our opinion that ground subsidence 15 not a significant hazard affecting this project site. However, site specific geotechnical studies should be completed for each development site. This should include continued consultation with the geotechnical engineer duning construction to determine if cavities may exist beneath planned structures. 4.0 CONCLUSIONS Based on our site observations and analysis, it does not appear as though geologic hazard considerations would be considered a fatal flawto the proposed site development and subdivision As discussed m Section 3, there are consideranons regarding geologic hazards and future site development may require additional analysis Site-specific geotechnical engineènng studies should be provided for any planned structures within the project area. 5.0 LIMITATIONS This study has been conducted based on the engineering geology standards of care in this area at the time this report was) prepared.

The services were completed in accordance with our proposal to you dated September 25, 2023, Proposal No. 23345P. We understand that you have elected to terminate our agreement and would like to be billed for only the time we have into the project to date. We understand the proposed project will consist of construction of a 35 to 40 foot bridge over Cement Creek which will be used to access a 12 lot subdivision. We understand the bridge that is currently being considered does not require a foundation. Ifplans change and foundation design parameters are desired, please contact us for additional information. A schematic showing the locations of our exploratory borings is provided below. : & TB-2 TB1 Figure 1: Locations of Exploratory Borings. Adapted from Google Earth. 649 TECH CENTER DRIVE SUITE A .

The subsurface conditions encountered are presented in the attached test boning Jogs. The logs present our interpretation of the subsurface conditions encountéred in the test borings at the time ofour field work Subsurface soil and water conditions are often variable across relatively short distances. It 1S likely that variable subsurface soil and water conditions will be encountered Free subsurface water was measured in both TB-1 and TB-2 at depths of approximately 5 feet and 6 feet after drilling fespectively. The laboratory stidy had been already initiated at the time of the request to terminate our agreement and the results of the laboratory tests are attached below. This study: presents the subsurface conditions at the locations indicated at the uime of dnllmng. This letter does not present any geotechnical engineering recommendations.

Preliminary planning is as shown on an attached LOCATION PLAN. individual properties are planned to be served with on-site water and wastewater utilities consisting of wells or cisterns, and on-site wastewater treatment systems (OWTSS). Fhave reviewed property planning. inspected the site from the road andby aerial drone surveillance, reviewed available resource mapping, and offer the following opinion of the feasibility of individual properties to support on-site water and wastewater utilities. While the region is generally suitable for on-site weil development for water supply. yield and quality can vary. The limited number of wells that exist nearby evidence suitable supply. It is expected that on-site well development is available and wil be successtul for all planned properties. From Colorado Department of Water Resources Information, the project area Is not a water critical area, nor an over appropriated area, therefore each lot Gan obtain a water well permit. The altemative of an on-site water cistem, supplied with off-site hauled water, is also available, Suitable site and soil conditions appear available for planning on-site wastewater treatment systems (OWTS) on all planned properties in the areas of planned building construction. The major soil type reported by the NCRS is a Needletonsiony loam, whichi is typically well suited for sanitary planning. NCRS mapping and soil description is attached. All OWTSS must be designed by a Professional Engineer at the time of permitting and construction, and reviewed and approved by the SanJuan County Public Health Agency, ensuring proper planning and compliance with ervironmental standards. individual design will vary based onsite specific site selection and soil testing. 38365 - Ss/ IONAL real tmnaerniva vaau espRFUR 4o 11320 odiny as l 000 970. e omes P09 00 111 Attachment M: Septic and Water Resource Letter from Engineer Maps (2) Lot 11 e 3 Lot 2 Lot 10 # Lot 3 2 / Lot 9 A I Lot / P Lot 8 1 2 a Lot 6 8 I Lot 1 3 e I B Lot 4 Lot 5 EXISTING DATA FROM GAIAGPS, SAN JUAN COUNTY GIS, AND PROJECT PROPERTY PLANS.

Catherine Condon on behalf oft the Southem Ute Indian Tribe. 4, The Division Engincer filed his Consultation Report with the Court on June 30, 2015, and his amended Consultation Report with the Court on July 10, 2015, pursuant to C.R.S., $37-92- 302(4) and that report has been considered by the Referee in rendering this ruling. 5. In Case Number 06CW116, the Applicant was granted a conditional water right for residential use for the Anglo Saxon Pond, Anglo 1 Well and Anglo 2 Well. The conditional right for the Anglo Saxon Pond for reservoir capacity adequate for storage and release of20 acre feet of water if call is placed. The pond to be filled by pump from the two wells with a diversion from Cement Creek to the Anglo Saxon Pond by a direct headgate for up to 2.5 cfs during periods of spring runoff and fill and refill at other times in priority. An outlet structure was to be constructed from the bottom of the reservoir or direct release to Cement Creek by or at the instructions of the Division Engineer. The Anglo 1 Well and Anglo 2 Well were granted a conditional right of 50 gpm from each well, maximum of 100 gpm combined withdrawal. A maximum of 2.5 cfs from Cement creek in priority for 140 dwellings with four occupants per dwelling on a continuous year round basis and totals an annual demand of 56.46 acre feet per year. Discharge of such uses to be a treatment plant. The Applicant was also granted a conditional right of2.46 acre feet per year of water for the commercial facilities. Discharge to the same treatment plant as the residential uses. The decree further granted the rights to a storage reservoir in the immediate vicinity of Cement Creek with a two acre surface storage area to be constructed on Applicant's property for purposes of storage and release of augmentation water. The two acre surface augmentation pond and one, one acre treatment pond will incur a total net evaporation of 3.20 acre feet per year. Total demand and consumption use for all sources on a one hundred percent occupation and use basis will not exceed 68.14 acre feet per year. The augmentation pond will require having 20 acre feet available at maximum build out for release to the Animas River, if a call is placed. Further, in order to provide adequate quantities of water to offset annual consumptive use of the project, Applicant will construct a reservoir, approximately two surface acres in size, capable of storing a total volume of20 acre feet. The reservoir will be constructed off channel sO that it can be filled during high flow spring runoff times of the year and refill in priority, stored in isolation from other surface water impacts and released to the stream system at the direction of the Division Engineer should the Animal River system come on call by as water right senior to bottom drain structure installed in addition to typical engineered Page 20f6 Attachment O: Water Rights Information spillways, overflows and outlet structures. The reservoir will contact active storage of 20 acre feet for the release to the system. 6. The Applicant has not yet applied for the well permits and the pond has not yet been constructed. 7. The Court finds that the Applicant is entitled to an appropriation date of February 28, 2005 for the rights granted herein. 8. The source of water for the Anglo 1 Well and the Anglo 2 Well is groundwater tributary to Cement Creek which is tributary to the Animas River. The source of water for the Anglo Saxon Pond is tributary flow to Cement Creek, tributary to the Animas River. 9.

Summary Attachment R: Cumulative Impact Report The Overland Estates Anglo Saxon Loads 1. Introduction This is a Cumulative Impacts Report for the proposed Anglo Saxon Estate Subdivision approximately 2.5 miles from Silverton on County Road 110 Administrator Willy Tookey noted that a Cumulative Impacts Report is required for this County Improvement Permit Application. County Zoning and Land Use Regulations Section 4-103 We have prepared this report in accordance with the County Zoning and Land Use Regulations Section 4-103. A Cumulative Impacts Report is required for this project, according to the County regulations. The range of area to be considered was changed in recent years from all properties within a two- mile radius to a "relevant area. Section 4-103, regarding cumulative impacts, is on the following two pages for your review. Page 1 Attachment R: Cumulative Impact Report Proposed Overland Estates Subdivision Anglo Saxon Loads STANDARDS FOR REVIEW The following general standards will be applied to any proposed development in the County. 1 The County recognizes that development or use ofi individual properties may have impacts on other properties, including Cowity roads. Further, the County recognizes that the cumulative impact ofi individual development or use of properties within an area may create impacts and service demands different from or greater than the impacts and service demands of an individual development proposal. Finally, the County recognizes that unless the potential cumulative effects ofdevelopment are considered in connection with each development or use proposal, future development and use of properties mayl be adversely affected or precluded because of effects caused by development or uses that are approved without consideration of cumulative impacts. Fr these reasons, the review process described herein requires the consideration of cumulative impacts ofall potential development and uses within an area in connection with any proposal being reviewed under this Chapter. 2 In conducting a review under Chapter 4 of the Code, the County shall consider all proposals in the context of all existing or potential uses of other properties in the vicinity of the proposed use. Unless a greater or lesser distance is required by the unique characteristics of a particular area, the vicinity of a proposed use shall be defined to be within a two mile radius of the proposed use or development. This shall: require consideration of each of the factors listed herein not just for the proposed use in isolation but rather in conjunction with all existing and potential uses of other properties in the vicinity SO as to permit the County to assess the overall impacts of development in the general area of thej proposed use. 3 All applications for review under this Chapter will be examined initially to determine whether thej proposal is consistent with the County's Master Plan. If consistent with the Master Plan, all applications will be reviewed to determine whether, based upon the objective facts contained within the record before the reviewing body: (a) The proposal will have anyadverse impact on public health, safety, morals or welfare. (b). Adequate potable wateri is available or can be developed to: safely support the proposed use, including fire control and suppression. (c) Adequate sewage disposal can be provided to support the proposed use. (d) Thep proposed use will have any adverse effect onj public or private property in the vicinity of the development. Page2 Attachment R: Cumulative Impact Report Proposed Overland Estates Subdivision Anglo Saxon Loads (e) Thej proposed use will have any adverse effect on scenic values, historic sites or structures, air or water or environmental quality. Wildlife (including habitat, food sources, migration routes, bunting, etc.), erosion or other geological condition. (f) Adequate road: access exists or can be developed to ensure access appropriate to the use, including access for emergency services. (g) Adequate utilities are or can be made available for the proposed use, unless deemed unnecessary or not practical. (h) Adequate emergency services exist to: serve the proposed use, unless deemed unnecessary or not practical. (1) There are natural hazards which may adversely affect the site or the proposed use of the site. (see Chapters 8-11 of this Code). 4 Ina addition to all other powers which the County may have with regard to review under this Chapter, the County shall have the authority to: (a) Require the: applicant toj provide evaluations, studies, reports, designs or opinions from qualified experts, approved by the County, with regard to: any of the factors listed above or with regard to the design or siting of any proposed development or use. (b) Require thej proponent to provide additional information with regard to any factor listed above to permit the County to make an informed decision regarding the application. (c) Condition approval of a proposal ont the elimination of any hazard, condition ore effect identified by the review process ori in Sections 1- 113 through Section 1-116 of this Code. (d) Require as a condition of approval the mitigation (either on the property where the use: is proposed or on public or private property, with the consent oft the owner) of any hazard, condition or effect identified by the review process or in Sections 1 113 through Section 1 116 of this Code. (e) Reject the application because of hazards, conditions or effects identified in the review process or in Sections 1- 1131 through Section 1- 1160 of this Code. In the event the County denies approval after review, the denial ofan application pursuant to this provision shall identify the hazard, condition or effect on which the denial is based. AI Land Use or Improvement Permit must be issued by the County when the County finds that the applicant hass sustained the burden of proof that the proposed development, activity or use, including best management practices, if any, does not present or create an adverse effect to the resources should it to be protected or utilized withini the overlaydistrict, or districts. Such a permit willl be denied when the County determines that the applicant has not sustained: such burden of proof. Page 5 Attachment R: Cumulative Impact Report Scope of Report The County regulations above (section 4-103) requires: The County shall consider all proposals in the context of all existing or potential useso ofother Properties in the vicinity of the proposed use. Unless a greater or lesser distance VS required by The unique characteristics of a particular area, the vicinity ofa proposed use shall be defined to be within the relevant area of the proposed use or development. The proposal" currently being reviewed by the County is a Minor Subdivision of equal number of build sites to original number of mining claims with building enveloped re-located from higher elevations to lower elevations for better access, safety and reduced impacts. This report contains information on the existing and potential development in the vicinity ofthe project site. For this report we evaluated the Adjacent Land Owner properties within 1500 feet of the exterior ooundaries of the project site. This includes all but one piece of privately owned For the purposes of this report we first have an overview of the 'proposal. Then we have attempted to evaluate existing, proposed, and potential development of the properties in the relevant area" vicinity ofthe project site. Then the criteria listed in the County regulations were used to evaluate the proposal and potential impacts. The scope of this report is to allow the County to review this proposal : in the context ofall existing or potential uses of other properties in the vicinity of the proposed use. 2. The "Proposal" The "Proposal," as described in County regulations section 4-103 above, is the proposed Overland Minor Subdivision, On The Anglo Saxon Claims 2.5 Miles up County Road 110 from Silverton in San Juan County, Colorado. A Preliminary Improvement Permit Application has been prepared by Lloyd Swartz which is being submitted to the County Administrator in May 2024, along with this report. For additional information please refer to the original Application binder, and the Preliminary-Final Plan Application attachments. Page 5 Attachment R: Cumulative Impact Report A summary of the "Proposal" is the subdividing of 3 Mining claims (one is a 40 acre Placer Claim) to create an equal number of claims or buildable 4-5 acre parcels that currently exist, (11) plus 1 whole claim being retained, accessed via an existing road on County Road 110 and 61 with year around plowed access from CR 110. This will include a section of new road, re- grading and a bridge over Cement Creek. Any Future Construction will require additional permitting and approval. Any homes proposed will require "engineered" septic system, well or a cistern for domestic water. Power and Phone are available to property lines. The site is approximately 148 acres and has been evaluated by and wetlands expert. 8 Claims and an Anglo Saxon EPA carve out will be set aside as green space. Please refer to the previously submitted documents and attached documents for additional information regarding the Proposal." 3. The "Vicinity" The "relevant area" we have selected for the "vicinity, I in order to evaluate development potential surrounding the project site, includes the properties located within 1500' of the Anglo Saxon and Transvaal claims plus the Tungston Load generally accessed from County Road 110. This encompasses all the closely associated mining claims in this area. There is a fairly sizeable public lands buffer between these properties and any other private in-holdings. As an overview of the properties in the vicinity of the project site, we have included some maps and plans on the following five pages. These are included in the original proposal and packet. Maps and plans for your reference on the following pages include the following: Adjacent Land Owner Map USGS Topo Quad Map with proposed plat overlay Anglo Saxon Property Map with Proposed Building Envelopes, Roads, Right of Ways and Bridge Location Map with Estimated Tree Removal Quantities Anglo Saxon Claims County Avalanche Hazards Map Anglo Saxon Claims Geohazards Map Photos of building envelopes and access points County/CDPHE Environmental Liability release Document The plans and documents following this page were used to evaluate the approximate existing and potential development of properties in the "relevant area" or vicinity of the project site.

S 29-20-104 and C.R.S. $30-11-101, et seq.; and WHEREAS, the United States Environmental Protection Agency ("EPA") and the Colorado Department of Public Health and Environment ("CDPHE") have and will conduct Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") response actions including, but not limited to, response actions selected in the Interim Record of Decision dated May 20, 2019 ("IROD") and possible other future CERCLA response actions, at portions of the Bonita Peak Mining District Superfund Site (collectively referred to as "CERCLA response actions"), in San Juan County; and WHEREAS, properties where CERCLA response actions have occurred within the Bonita Peak Mining District ("BPMD" or "Site") are more fully described in the inventory of Remediated Mine Waste Source Areas, attached hereto as Attachment A ("Inventory"), and as may be modified from time to time and maintained within the Office of the San Juan County Clerk and Recorder for public viewing. Specifically, the subject CERCLA response actions may include: managing acidic water discharging from mine portals with diversion trenches; diverting storm water around mine waste piles; maintaining existing mine portal sediment ponds; excavating in-stream mine wastes; and containing and isolating contaminated soils at mine- impacted recreation staging areas using covers; and WHEREAS, prior to the BPMD Superfund site listing, non-CERCLA reclamation measures were implemented on other Mine Waste Source Areas in San Juan County within and beyond the BPMD. These sites may be more fully described in the Inventory, as may be modified from time to time and maintained within the Office of the San Juan County Clerk and Recorder for public viewing. Specifically, the subject non-CERCLA reclamation measures may include: managing acidic water discharging from mine portals with diversion trenches; diverting storm water around mine waste piles; maintaining existing mine portal sediment ponds; excavating in-stream mine wastes; and containing and isolating contaminated soils at mine impacted recreation staging areas using covers. Page Attachment R: Cumulative Impact Report 4. Existing and Potential Development of "Vicinity" Properties The County regulations require that we include within this report a description of the existing and potential development in the Vicinity of the project site. List of Criteria Used to Evaluate the Development Potential of "Vicinity" Properties We have prepared a table listing in alphabetical order the properties in the relevant area" vicinity ofthe project site. The table includes the following property information and criteria used to provide a cursory evaluation of the existing and potential development ofthe properties. Property Name The names of the claims were determined using the County Assessor website. The property cards on the Assessor website were used to review each parcel. United States Mineral Survey Number All available US Mineral Survey Plats associated with these claims were obtained and reviewed, using the BLM GLO website. These USMS Plats are the original surveys from approximately 100 years ago. They were reviewed in order to fill in the names of the mining claims. Owner(s) Ownership ofthe majority of mining claims in this clustered area are by Lloyd and Esther Swartz as part of the subject parcels. Acreage Most claims are 10 Acres or slightly less due to senior claim overlaps. Page Attachment R: Cumulative Impact Report Access Our evaluation of the mining claims in the vicinity included a check to see if each property appears to have a County Road pass through its property boundaries, indicating the property currently appears to have legal written access. Both CR 61 and CR 110 were evaluated. All but 2 claims would require new roads, right of way permission from the Anglo-Saxon owners and in some cases the BLM. The Aire lodge and Ajax have direct access to CR 110 and existing structures consisting of a cabin and a small lodge with a handful of guest rooms. The lodge is still under construction. Additionally, there is a seldom used, seasonal Cabin on the Munzer Claim, originally built on BLM land but gained legal status with a BLM settlement in 2023. This cabin has no legal access at this time, the owners Cross the Anglo-Saxon properties through the creek. In theory the Porcupine could access the end of CR 61. However, it is a vertical, unstable cliff and is unlikely to see a road or driveway. An easement for parking on the Anglo Saxon Claims was granted to Aire Lodge and a proposed easement for the Prodigal Sun has been surveyed. Owners are open to granting further easements should they be requested. However, we have been communicating with the property owners most likely to need access by road. The Prodigal Son and Munzer. Other properties may be completely impractical, or extremely expensive to build roads to and may never see development. Tundra The Peerless and Queen City Lie above tree line. According to the interpretation of current County regulations, requiring adequate screening of new structures, and prohibiting almost all development occurring on ridgelines and/or located on alpine tundra, these claims which are mostly tundra can be considered unlikely to be developed. Potential Avalanche and Geologic Hazards We have utilized the County's adopted Avalanche Hazard Map and the County's adopted Geologic Hazards Map to provide cursory information regarding potential hazards for each of the mining claims in "The Vicinity". Some private properties would be required to obtain a site-specific avalanche and geo hazards study, prepared by a qualified expert. Properties that appear to be located almost entirely in probable avalanche red zone areas, properties that are located almost entirely in the floodplain, directly below rock fall areas, and/or in known debris flow (mudslide) areas, can generally be considered unlikely to be developed. Cursory Evaluation of Reasons a Property Is or Is Not Likely to be Developed A cursory evaluation is provided on the table, listing the reason(s) likely to allow for, or limit, future potential development of a property, which in this instance primarily has to do with challenging access and road construction requirements. In one case geologic hazards could play a part, but Tundra, Mine waste, and Ownership really do not play a role with most of these Page Attachment R: Cumulative Impact Report Development Potential We have summarized the likely overall potential for development on each property. Table of Vicinity Properties and Cursory Evaluation of Development Potential The table on the following page summarizes the existing and potential likely future development in the "vicinity" of the project site.

Here is a summary of the cursory evaluation of the existing and potential development. Existing Cabins The following 3 properties known to have an existing residential cabin structure: Ajax MS Lode, owned by Nielsen Douglas A and Dana A of Arvada CO. Small, newer cabin of good condition. Munzor Lode, owned by Daren Hillery of Albuquerque New Mexico. Cabin was illegally built on BLM land in the 1950's and in 2023 arrangements were made to expand the parcel with the BLM. Currently has no legal access and uses an existing 4x4 road to cross cement creek. We anticipate granting a ROW at some point across Overland upon request. Cabin is small, and rarely ever visited. Treasure Lode, Aire Lodge owned by C&G Alpine Partners. Currently under construction scheduled for completion 2025 with room for up to 12 guests. Winter Time parking is via an easement on the Anglo Saxon Placer ofOverland Estates. Vacant But Likely to Be Approved Prodigal Son Lode, Owned by Graham Steven Lee and Chandler Michael of Pagosa Colorado. Overland Estates has issues a right of way for a road across the Anglo Saxon claims to access their mule trail. And the have expressed intentions for a future, seasonal cabin. Properties Which Could Be Developable The following 2 properties appear to be potentially 'buildable, and could be approved in the future for proposed residential use: The Gold Bug #2, Owned by Frank and Catherine Newman which could be buildable, pending acquisition of rights of way. The Gold Bug, Owned by Cook David of Colorado Springs which could be buildable, pending acquisition of rights of way. Page 23 Attachment R: Cumulative Impact Report Possibly Developable, But Unlikely to be Listed for Sale The following 2 properties could possibly be developable, depending on results of closer site evaluation; however, they are unlikely to be sold individually for residential development, because they are currently owned by a mining environmental trust agency managed by lawyers. These two claims are held by an ownership type which is historically unlikely to sell, and they are located far away from legal access. Muldoon Lode Gold Bug #1 Lode Properties Which Appear to Be Unbuldable/Unable to Comply with County Regulations The following properties appear unlikely to be developed, based on cursory evaluation, due to lack of feasible access, apparent significant avalanche and/or geologic hazards, lack of acreage, predominantly located above tree line on alpine tundra, etc. The following properties appear unlikely to ever be developed: Peerless Lode Queen City Lode Porcupine Lode Pride ofThe Rockies Lode Pride of Cement Lode Colorado Belle Lode Independence Lode Tungston Lode Page 24 Attachment R: Cumulative Impact Report Summary of Development Potential of Vicinity Properties In summary, the vicinity has the following estimated development potential: 3 Property Known to Have an Existing Cabin 1 Property Likely to Be Approved for a Proposed Cabin 2 Possible Future Cabins 2 Possibly Buildable but Unlikely to Be Sold 8 Probably Not Developable Claims 16 Total Vicinity Properties Evaluated (Including One Project Site). Therefore, based on a cursory evaluation of the 16 properties in the selected "relevant area" or "vicinity," we would foresee a total of perhaps three cabins being constructed in the future, in addition to 3 known existing cabins in the area. The County regulations (on page 2 of this report for your reference) state that the County shall consider all proposals in the context of all existing or potential uses of other properties in the vicinity of the proposed use. I Page 25 Attachment R: Cumulative Impact Report 5. Evaluation of the "Proposal" Using the Criteria Listed in the County Regulations The County regulations (included on pages 2 and 3 of this report) require the County to evaluate the 'proposal" (the Proposed Overland Estates Subdivision on the Anglo Saxon Loads) "in the context of all existing or potential uses of other properties in the vicinity of the proposed use. I The individual factors listed in the County regulations to be evaluated for the "proposal" (in the context of the existing and potential vicinity development) are the following: ift the proposal will have any adverse impact on public health, safety, morals or welfare if adequate potable water is available or can be developed to safely support the proposed use, including fire control and suppression if adequate sewage disposal can be provided to support the proposed use if the proposed use will have any adverse effect on public or private property in the vicinity if the proposed use will have any adverse effect on scenic values, historic sites or structures, air or water or environmental quality, wildlife (including habitat, food sources, migration routes, hunting, etc.), erosion or other geological condition if adequate road access exists or can be developed to ensure access appropriate to the use, including access for emergency services if adequate utilities are or can be made available for the proposed use, unless deemed unnecessary or not practical if adequate emergency services exist to serve the proposed use, unless deemed unnecessary or not practical if there are natural hazards which may adversely affect the site or the proposed use ofthe site The County regulations state that An Improvement Permit must be issued by the County when the County finds that the applicant has sustained the burden of proof that the proposed development, activity or use, including best management practices, ifany, does not present or create an adverse effect tothe resources sought to be protected or utilized.. This section of the report includes evaluation of the above listed criteria. Impact of the Proposal on Public Health, Safety, Morals, and Welfare The County regulations require that you consider the following: .in the context of all existing or potential uses of other properties in the vicinity of the proposed use. if the proposal will have any adverse impact on public health, safety, morals or welfare. Page 26 Attachment R: Cumulative Impact Report The "proposal" is the Proposed Overland Estates Subdivision on the Anglo Saxon Loads. The overall impacts to public health, safety, morals and welfare which could be caused by approval of this project are expected to be negligible. The Maximum number of potentials cabins is 12 spread out over approximately 80 acres with an additional 68 acres of green space as well as most surrounding land being public land in the thousands of acres. It can be assumed that there will be very little traffic generated by the additional of 12 seasonal or in a few cases year around cabins. County Road 110 is a large road with significant capacity and currently serves the Gladstone Mining District, Silverton Mountain and a number of other homes and businesses. It may be a decade or more before homes are built and not all will likely be year around inhabited. We do not expect that the Applicant will be doing anything in the proposed minor subdivision would negatively affect the morals or welfare oft the public. The proposed minor subdivision if approved could generate some local jobs, and an increase in sales tax/County taxes, and 12 potential YEAR AROUND homes sites which are in severe demand and which could positively affect the public welfare. We believe that all proposed activities and uses will have some impact or effects. For the purposes of the County review process, we believe the County could consider if a project is relatively modest and reasonable, and if the Applicant has taken steps to minimize all of the impacts which are possible to control. Overall, this project can probably be expected to have a negligible impact on public health, safety, morals, and welfare. Adequate Water The County regulations require that you consider the following: .in the context of all existing or potential uses of other properties in the vicinity of the proposed use... if adequate potable water is available or can be developed to safely support the proposed use, including fire control and suppression The proposal" does not include provisions for water, but does include water rights far beyond what is required and individuals may choose to use surface supplace, hauling or wells. There is a creek, and ponds close enough to serve any fire fighting resource needs. Overall, it appears that the Applicant is attempting to provide adequate potable water to safely support the proposed use. Adequate Sewage Disposal The County regulations require that you consider the following: Page 27 .in the context of all existing or potential uses of other properties in the vicinity oft the proposed use.. .if adequate sewage disposal can be provided to support the proposed use. Any future cabins would require an approved septic system to be designed in accordance with the State and local regulations. The Maximum number of potentials cabins is 12 spread out over approximately 80 acres with an additional 68 acres of green space as well as most surrounding land being public land in the thousands of acres. Overall, it appears that adequate sewage disposal can be provided to support the proposed use. Effect of the Proposal on Public or Private Property in the Vicinity The County regulations require that you consider the following: .in the context of all existing or potential uses of other properties in the vicinity of the proposed use... .if the proposed use will have any adverse effect on public or private property in the vicinity. The section ofCounty regulations above asks, will this project have any adverse impact on public or private property? All building envelopes and even roads will be very hard to see if at all from the nearby County Road system, which creates no impact to the nearby public and private land. Additionally building envelopes have been evaluated as having little to no visibility from the existing, seldom used Munzor Load cabin, and are not visible to any other existing structures. The owners asked we include a provision to install a gate on the new access road in the future to prevent additional traffic and potential break ins to their cabin. This is noted in our proposal. Overall, the project appears to be reasonably modest, with the anticipated impacts to the nearby public and private lands expected to be minimal. Effect of the Proposal on Scenic Values, Historic Sites and Structures The County regulations require that you consider the following: .in the context of all existing or potential uses of other properties in the vicinity of the proposed use... if the proposed use will have any adverse effect on scenic values, historic sites or structures, Page 28 Attachment R: Cumulative Impact Report The Applicant has selected the least visible location for the proposed building envelopes using areas of on-site existing vegetation to minimize visual scenic impact. The only true historical structure is the cribbing wall on CR 110 and the nearest building envelope has extensive screening with more growing in. Overall, the impact to scenic values, historic sites and structures is expected to be minimal. Effect of the Proposal on Air, Water and Environmental Quality The County regulations require that you consider the following: .in the context of all existing or potential uses of other properties in the vicinity of the proposed use... .if the proposed use will have any adverse effect on air or water or environmental quality. Since any future cabin construction is required to be in compliance with all applicable Local, State, and Federal regulations, regarding air, water, and the environment, the impacts of the proposal to the air, water, and environmental quality are expected to be minimal. Effect of the Proposal on Wildlife, Erosion, and Geological Conditions The County regulations require that you consider the following: CUMULATIVE IMPACTS REPORT Proposed Overland Estates Subdivision Anglo Saxon Loads .in the context of all existing or potential uses of other properties in the vicinity of the proposed use... if the proposed use will have any adverse effect on wildlife (including habitat, food sources, migration routes, hunting, etc.), erosion or other geological condition. Page 29 Attachment R: Cumulative Impact Report All existing/proposed activities/uses have some sort of impact. The effects of this project, however, on wildlife, hunting, migration routes, habitat, and animal food sources are expected to be minimal. There is not any significant tree clearing proposed for this project, which is expected to keep effects on wildlife to a minimum. Erosion is not expected, as road lay outs are mostly on flat ground and designed to minimize run off. SME engineering was hired to conduct a survey of wetlands and environmental impacts. Some Fens were found and tested to confirm the existence. All proposed roads and building envelopes were laid out to give these areas a wide birth. Additionally, "emergent" wetlands, or areas with wetlands type vegetation were discovered. Despite the impacts to these areas being minimized we are well under .03 of an acre is anticipated to be impacted after numerous revisions to our lay out. Despite the limited impacts we did acquire a Army Corps of Engineers permit to assure compliance and a structure of rules to avoid excessive impacts. Given the limited density of construction of roads and future potential build sites habitat, food sources and migration are not expected to be affected. Not to mention most surrounding land is non-developable as public land. Additionally, by setting aside nearly 50% of the acreage as Green Space we are able to have responsible development while; Limiting future, new road construction and related impacts Preserving high-altitude wetlands and Fens Preserving important high-altitude habitat and Tundra Support the EPAs ongoing water quality improvements Adequate Road Access The County regulations require that you consider the following: .in the context ofo all existing or potential uses of other properties in the vicinity of the proposed use... ..if adequate road access exists or can be developed to ensure access appropriate to the use, including access for emergency services. Page 30 Attachment R: Cumulative Impact Report County Road 110 passes through the project site. The site has legal access via the existing County Road system. The proposed minor subdivision will be accessed from a loop road on the North Side consisting of a new section of road and a bridge on the new section to provide for first responder access to existing properties and cabin as well as new that does not currently have adequate access. This loop will provide summer time emergency egress and an avalanche free escape route for 7 of 12 Parcels. For 5 Parcels a summer-maintained CR 61 of good condition will provide short access from CR 110. It appears that adequate road access exists to ensure access appropriate to the use. Adequate Utilities The County regulations require that you consider the following: .in the context of all existing or potential uses of other properties in the vicinity of the proposed use... .if adequate utilities are or can be made available for the proposed use, unless deemed unnecessary or not practical. Water will be hauled and placed into a proposed cistern, or wells drilled if someone chooses to build a future cabin and a septic system is being designed by a Licensed Professional Engineer. On 5 acre remote lots a septic system with an approved engineered design may be installed. Power is available to the property lines as well as phone and cable. Additional options for solar and star link access also exist. Overall, it appears that adequate utilities can be made available for the proposed use. Adequate Emergency Services The County regulations require that you consider the following: ..in the context of all existing or potential uses of other properties in the vicinity of the proposed use.. .if adequate emergency services exist to serve the proposed use, unless deemed unnecessary or not practical. Page 31 Attachment R: Cumulative Impact Report Access for emergency services is comparable with most other developed claims, and appears relatively adequate for the proposed use. There will be times of no vehicular access, due to avalanche/debris flow related County Road closures of County Road 110, and non-plowing of County Road 61. It is possible that private plowing of CR 61 may be negotiated in the future since it only accesses this private set of build sites and does not offer any snow mobile or ski trails use. The new road includes an 80,0001b rated bridge to accommodate emergency services and is easily plowed privately. Emergency services are less than 3 miles across all plowed county and city roads to the property with under 10 minutes response time. Natural Hazards The County regulations require that you consider the following: .in the context of all existing or potential uses of other properties in the vicinity ofthe proposed use... .if there are natural hazards which may adversely affect the site or the proposed use of the site. There are natural hazards at the site, including the nearby Grassy Gulch avalanche area. However not is not expected to preclude development or adversely affect any future structures as building envelopes are far outside of the mapped slide zone. An existing cabin from the 1950s has further not seen any damage despite being in a likely "Blue Zone" near the mouth of this limited slide.. 6. Summary This is a Cumulative Impacts Report for the proposed Overland Estates Minor Subdivision, located on the Anglos Saxon Loads in San Juan County, Colorado. The Sketch Plan application for a San Juan County Improvement Permit Application was prepared by Feeney Architects. A Preliminary plat and application for a San Juan County Improvement Permit and building permit Application has been submitted to the County Administrator with this Cumulative impact supplement. An Improvement Permit is required in order to use a mining claim for residential use, and would be the responsibility of future owners wishing to build a cabin or permanent structure. This Cumulative Impacts Report has been prepared by Lloyd Swartz with Camino Real Estate Holdings, LLC. Page 32 Attachment R: Cumulative Impact Report County Zoning and Land Use Regulations Section 4-103 requires that all proposals be reviewed ..in the context of all existing or potential uses of other properties in the vicinity of the proposed use.. The properties in the vicinity of the project site have been evaluated for development potential. We evaluated 16 properties in the Vicinity. Our evaluation was cursory based on Assessor information, original mineral surveys available on the BLM GLO website, and available maps. Closer evaluation of an individual propertyi including a survey could produce different results. We found that 3 nearby properties are known to have an existing cabin, one additional property is likely to be approved for residential use, two additional properties could possibly support a cabin sometime in the future, two properties appear possibly buildable but are unlikely to be sold individually by the mining environmental trust legal firm, and the remainder of the properties in the vicinity appear to be unbuildable. Development evaluation criteria generally included: access, avalanche hazards, acreage, prevalence oftreeless tundra, and the ownership. In summary, we would anticipate that perhaps no more than three additional cabins are likely to be constructed in the future in Anglo Saxon Claims Vicinity, with a maximum of 12 on 148 acres ofthe subject property. The majority of the parcels near the project site appear unlikely to ever be developed, mostly due to a combination of obstacles such as avalanche, tundra, ownership, and lack of access. We then evaluated the "proposal" using the factors listed in the County regulations, which are to be considered ..in the context of all existing or potential uses of other properties in the vicinity of the proposed use... These factors included impacts of the proposal to: public health, safety, morals, and welfare, public and private properties, scenic values, historic sites and structures, air, water, and environmental quality; adequate site access, water, sewer, utilities, and emergency services; and presence of natural hazards - when considered in the context of nearby existing and potential development. Overall, although we believe that all uses and activities of any kind cause some impact, it appears that the proposal has been thoughtfully designed by the Applicant and the Project Architects to create as little as possible impact on the public health, safety, and welfare, and surrounding properties. The County regulations state that An Improvement Permit must be issued by the County when the County. finds that the applicant has sustained the burden of proof that the proposed development, activity or use, including best management practices, if any, does not present or create an adverse effect to the resources sought to be protected or utilized... Page 33 Attachment R: Cumulative Impact Report It appears that the Applicant has sustained the burden of proof that the anticipated impacts will be relatively minimal, and that efforts have been taken to limit any impacts. We suggest that the minor subdivision proposal for the Anglo Saxon Load Claims can be approved by the County, in accordance with the San Juan County Zoning and Land Use Regulations Section 4- 103.
