The system has been designed in accordance with the current Garfied County Environmental Health Department's On- Site Wastewater Treatment System Regulations. 1 .{"} {}rsrz*rn|'4n{*rrnmLA*t* i "1 *xixti*g {}*rzdilusrz:'i The propedy described as 12730 Highway 82 is located in Garfield County just outside of Carbondale, Colorado. The site is designated as Property lD #239327400027. The property borders lots with developed residences to the west and east. An undeveloped lot borders the southern property line, while Highway 82 runs along the northern border of the property. . ,:iir:r:i *.;:t4 .,; a"t,::\ Figure 1 - 12730 Hwy 82 Vicinity Map from Garfield County GIS Mapping The 2.S-acre lot is undeveloped aside from a short, existing driveway access. The lot slopes to the south towards the Roaring Fork River, with the general grade of the site spanning between 10-20%. Then the site transitions to a cliff nearthe bank of the Roaring Fork River. The existing access to the property exits off Highway 82 and crosses over an existing cattle guard before reaching the property. The existing gas and overhead electric service run along the northern property line within the 20' utility easement. An existing community water service line also runs alongside the northern property line. There is currently no Onsite Wastewater Treatment System (OWTS) infrastructure on the site. '',.: , L 3 Site 0610412024 i .2" #xixtirsg &rsil *rsru*itusrzrt Crystal River Civil (CRC) was onsite for the exploratory profile pit excavations on November 1, 2023, to observe and sample the subgrade soils near the proposed Soil Treatmenl Area (STA) location. Each pit was excavated to approximately eight feet deep from existing grade. Photos of the excavated profile pits are shown below. Figure 1 - Profile Pit 1 Figure 3 - Sol/s From Profile Pit 1 406104t2024 @D l(ilIfiIilNflY[I Figure 4 - Profile Pit 2 Figure 5 - Soils From Profile Pit 2 The first profile pit was located on the southeast side of the anticipated soil treatment areas, approximately 15 feet from the northern property line. The first layer consisted of approximately six inches of topsoil, with native grasses at the surface that needed to be removed for the dig. The following four feet of soil consisted of a light reddish-brown clay material present with a strong structure. As excavation proceeded, the soil transitioned quickly at four feet to river cobble with weak soil structure between. The soil between the rocks was sandy or sandy loam, so the pit walls continued to erode throughout the dig. The stones varied from two to six inches initially at four feet deep, then increased in diameter with depth to up to a foot in diameter at the bottom of the pit. Pit excavation ended eight feet deep. A soil sample was taken four feet below the surface. No groundwater or any indication of groundwater was apparent from oxidation or discoloration of soils. Excavation of the upper layers was easy but was difficult once the layer with cobble was encountered. The next pit was located at the southeastern corner of the anticipated soil treatment area, approximately one hundred feet west from Pit 1. Pit2 had very similar traits to Pit 1 and included 6 inches of topsoil and organics. The next five feet of soil appeared to be a reddish-brown clayey material with minimal rock content. A soil sample was taken at 5 feet deep, where the soils transitioned once again to the lower layer of river cobble. Excavation continued through the cobbly soils to the bottom of the pit. Soil texture continued to be weak and the lower layer int the pit continued to collapse throughout the dig. There were no signs of groundwater present in the entire pit. Both pits were backfilled after photos were taken. Both pits exceeded 65% of rock content from visual inspection and were assumed to be closer to75o/o. 506t04t2024 Each sample from the profile pits was analyzed at the lab in order to properly identify the soil type for STA sizing of the OWTS. Gravel content of each sample was completed by using the gravel content by volume method after breaking up all soil peds present in each sample. Each sample indicated 43 percent and 37 percent gravel content by volume for Profile Pits 1 and 2, respectively. The soil samples did not accurately portray the higher level of rock content seen in the field due to the size of the rocks that were not collected in the sample. lmported material will be necessary for the OWTS. Each of the soil samples found in the pan that passed a No. 200 sieve was then analyzed using the soil texturing by feel method to determine the soil type. Each sample barely formed a ball when squeezed, and each formed a ribbon less than one inch long before breaking. Therefore, it was determined that the soil type is 1 due to its lack of structure, according to Table 10-1 of the Garfield County OWTS Regulations. When excessively wetted, the soil samples felt gritty to the touch. Determining that the soil for each profile pit is identified as a "Loamy Sand". A long-term acceptance rate (LTAR) of 0.8 for Treatment Level 1 (TL1) shall be used for the receiving soils of the OWTS. Given the rock content exceeded 35% and is soil type 1, the soil type R-0 was adopted, requiring a 0.8 LTAR for a 3 foot deep secondary sand media filter. This LTAR value has been used to accurately size the STA, further defined within this report. All soil texturing and testing procedures followed the Colorado Department of Public Health and Environment (CDPHE) Regulation 43 soil evaluation process as taught and certified by Colorado Professional in Onsite Wastewater (CPOW). Refer to the images below for soil testing. Figure 6 - SorT Samp/e Sieve Analysis Pit 1 606104t2024 Figure 7 - No. 200 SorT Samp/e From Pit 2 Figure 8 - Performing Texture By Feel Test On Pit 1 Figure 9 - Performing Texture By Feel Test On Pit 1 1.3 Fr*p***d **nditi*n* The proposed site consists of the construction of a workshop in the center of the site, with garage space on the lower level and living space above. An improved access with turnaround area will transition into the structure on the northern side. A large area to the west is to be left undeveloped with the anticipation of a future residence. Minimal landscaping on the site is currently proposed, Due to lack of sanitary sewer infrastructure in the area, an OWTS is required to treat wastewater from the development. The proposed system has been designed to treat wastewater for four bedrooms - one for the proposed structure, then 3 for the future residence. All offsets from the river, property lines, structures and utilities will be met. A well is proposed in the northwest corner of the site, a decent distance away from the OWTS and the Soil Treatment Area. n; {\ {\\hf 'T,'q mt-"\.t \-/ 4a v e *'u*{itlfi{3 3."3 ffifflu*nt Fl*ws The OWTS has been designed to treat wastewater for a single-family residence and an additional dwelling unit, or ADU, above the garage for a total of four bedrooms. Per Table 6.1 of Garfield County OWTS Regulations, the OWTS for a four-bedroom residence will be required to treat an average daily flow of 525 gallons per day (GPD). This is equivalent wastewater flows for 7 people 70610412024 occupying a residence in a single day, at 75 GPD per person. No additional flows are anticipated or accounted for in the OWTS design for a single-family residence with an ADU. ?..?" S*t*r*';V"r; All setbacks for the OWTS shall be met. This includes 50 feet from the river, 25 feet from potable water lines, 25 feet from subsurface drainage structures, 20 feet from proposed structures with basements, and ten feet from property lines according to Table 7-1 of the Garfield County OWTS Regulations. 2.3 *r:pti*TarzW" The minimum septic tank size for a four-bedroom residence is 1,250-gallons, per Table 9-1 of the Garfield County OWTS Regulations. One 1,25O-gallon, two-compartment, top seam septic tank, provided by Valley Precast, or approved alternate, will be used for the OWTS. The combined tank sizes also meet the minimum detention time for effluent of 48 hours, which is industry standard. The septic tanks will bring the wastewater effluent to Treatment Level 1 (TL1), which will be used to accurately size the STA. The septic tank will have two compartments, with the second compartment housing the duplex pumping system designed to pump effluent to the soil treatment area. The total capacity of the tank is 1,259 gallons. Eight-inch effluent filters shall be included on the outlet tee of the septic tanks. The tanks will have between one to four feet of cover from finished grade. Water{ight risers shall be installed to bring the manhole access points of the septic tanks, flush with finished grade. The tanks are to remain easily accessible for regular maintenance purposes. 2".4 WurxSs ffiynt*rn A pump system was chosen to keep the soil treatment area size reduced, due to site constraints from setbacks and the delineated activity enveloped shown on the survey. A 1.5" Sch-40 PVC discharge line is routed to a high point in the system then down to the soil treatment area. These distances and elevations are used to accurately specify a pump system for the OWTS. Using the Orenco Pump Select program, an Orenco P3005 duplex effluent pump package system shall be used. The floats inside the secondary treatment unit shall be set for a dose of 17 gallons, which is approximately five times the volume per zone after the ADV. This also allows for approximately 3 gallons of drain back to the pump tank as well. Per the peak anticipated flows, the septic pump system will run approximately thirty times per day. A pump curve and report are included within this report. An Orenco control panel shall be installed near the residence for adequate alarming. 2.* "$*iE " { r*at{vi*{1l hr*a *ntr;*lati*tzs To size the Soil Treatment Area (STA), ihe average daily flow of 525 gallons per day and a LTAR value of 0.8 for Treatment Level 1 with a R-0 Soil Type was used. The minimum STA using these parameters for a pumped system using bed configurations is 656 square feet with a 3-foot-deep unlined secondary sand media filter. All reductions described in Tables 10-2 of the Garfield County OWTS Regulations were used to calculate the minimum STA size. The STA for the proposed OWTS is proposed as a symmetrical, single-bed configuration that is 12 feet wide and 56 feet long. This STA configuration will include distribution media consisting of a gravel dispersion bed over the 3-foot-deep unlined sand filter, covering 672 square feet total for the STA. Refer to the calculation below used to determine the STA. The infiltrative layer of the OWTS shall be installed within four feet deep from existing grades present, and the sand media must extend I0610412024 within the river cobble layer below the clayey soils. Cover over the distribution chambers shall also be at least one foot. lf unsuitable or differentiating soils are discovered during the installation of the STA, design revisions will be necessary. CRC shall be contacted immediately upon discovery or for inspection. All changes are to be resubmitted to Garfield County Environmental Health Department for review and approval. 2.# L{{l**n1" *t*Lri1suli*n To evenly distribute effluent to each zone within the STA, the septic pump will dose the STA through a 1.5-inch Sch-40 transport line with a high point located between the tank and the STA" A manifold shall be used prior to entry into the STA to supply the distribution rows. The distribution piping laid within the gravel dispersion system is proposed to be 1.S-inch Sch-40, perforated PVC. An orifice size of 5/32-inch diameter and a spacing of five feet O.C. is to be utilized, with orifices facing downward. A5132" diameterorifice shall be installed atthe end of each distribution lateral, facing downward. The distribution laterals are to be installed as level as possible within eaclr bed. Three feet of secondary sand media will be installed at the base of the gravel dispersion and will meet Garfield County OWTS Ruies and Regulations. The gravel dispersion is to be covered by native, uncompacted material. One foot of topsoil will be installed to the finished grade elevation over the STA. lnspection pofts are proposed to be installed at each corner of the STA, where the I Gallors Per RoomNo. Bedrooms 150 ,Additional Flow Treatmerrt Level LTAR Gravity Dosed (Siphon or Pump)Pressure Dosed Diskibution Media Trerch Chambers Bed Design Flow {gaUday)525 Min- Septic Tarrk Size 9-1 1 250 Required ln{ilkative Area 656.25 Rows Row Lergth ift) 2 109.4 3 72.9 54.7 5 43.8 6 .lh 5 7 31 3 s 24.3 10 21.9 1'1 1q I 12 18.2 0610412024 system starts and ends.

A cleanout is proposed within five feet of the structure. The grinder pump will then convey the sewer via a 2" sch-40 line to the septic tank to the east. From the septic tank to the high point within the transport line, the piping will be installed with a slope of five percent towards to the septic tank for drain back purposes. From the high point to the manifold, a 1.S-inch Sch-40 PVC line will be used with a minimum slope of two percent towards the STA for drain back purposes. All transport and rnanifold lines from the ADV to the STA will be 1.S-inch Sch-40 PVC. Transport lines are sloped at a minimum of two percent, while manifold lines are to be installed level for even effluent distribution to the distribution laterals. All piping will be bed with six inches of washed screened rock or class six aggregate base course. The minimum cover over all lines shall be five feet from finished grade. One inch of insulation per foot of cover not achieved shall be installed for any lines under four feet of cover. 3.t3 {}*rzr*t"r*r;LAtsrz ,*rzr} T:'frr'*ir;"7t{:}{i&Ti{:* ry{';3{:#*,}ttl#:'; 3"1 **n*tru*ti*r"r I'J*t*,s The contractor is required to notify CRC prior to the start of construction on the OWTS. Gommunication between the contractor and CRC is expected throughout the installation process. Any discrepancies, concerns, or field discoveries shall be brought to the attention of CRC immediately. Any changes on the design are to be confirmed with CRC and the Garfield County Environmental Health Department. The area for the STA is required to be fenced off to all construction vehicles and equipment, and no materials are to be placed on the STA. The STA is to remain uncompacted throughout the duration of construction, especially after STA installation. Topsoil must be placed above all disturbed areas due to OWTS construction. Native grass seeds will be installed on stable slopes for quick revegetation. lnstall erosion control measures in specified areas until revegetation is established. The owner and contractor are responsible for ongoing revegetation practices. No trees or shrubs shall be installed in the vicinity of the OWTS, and livestock and pedestrians are required to be kept off any OWTS components, especially the STA. CRC shall be notified of completion of the STA prior to backfill for inspection. CRC shall also be notified after startup of pump system has been completed by pump supplier for inspection. 3.?, {}WT# t'lX*ir:lfierzmn** Routine maintenance shall be completed as specified in section 43.16 of the Garfield County OWTS Regulations. Septic tanks must be inspected and cleaned or pumped every two years, or as needed by observing the amount of solids within the tank. The STA is to be inspected every six months. Service contracts are necessary at all times for manufactured units and any other component requiring maintenance. The owner shall be cognizant of waste being added to the OWTS. Garbage disposal system use is not to be frequently used. Compostable toilet paper is recommended, and non-biodegradable 0610412024 10 materials shall not be flushed into the OWTS. Grease should never be placed in drains and all areas within vehicular storage are to use a grease interceptor if connected to the residential plumbing system. Mechanical room drains and water softener discharge are not to be connected to the OWTS. All plumbing fixtures and appliances must be routinely inspected to ensure there is no constant leaking into the OWTS. Plumbing leaks or constant discharge will overload the OWTS system and will then not function as designed. The OWTS described in this report is for domestic wastewater only. lf there are any questions on the design or any sections within this report, contact CRC directly. & n &nrtr*rtrlir'r**."-t "v avs\nww 0610412024 11 :,::--::-*---::.- NE'A!PdHor€cshdrysbdilG :re o,s. o4i,.hdr. eJrp sFreJr€, tudh*hs!c!€'cr ^i.S@ a\'' troa:i.6io& rshrd h B$i id Oi $d\ AJ-rl Ccnro Frii rc3. ii3 F r - i1*51 S.,.r.6rrd 50 .t I I I -.1l I / 91}oh tk,r Fo&ea€4q, ;: d,l$l--)ol,wffi oq Nc o o N @O GOix BEiu ffi I I o o J I \\ilt\V Ii 1", l3ll l- 4 lgFil;; i;ls illl ""l;{ l; r' Irglblat=- t-I: E !

June 4,2024 Existing Conditions The property described as 12730 Highway 82 is located in Garfield County just outside of Carbondale, Colorado. The site is designated as Property lD #239327400027. The property borders lots with developed residences to the west and east" An undeveloped lot borders the southern property line, while the Highway 82 Right-Of-Way runs along the northern border of the property. t :::t ::,\,.ft1? -z&. - '.,r'i, !lJa!, . ::: Shown above is an image of the Garfield County G/S Map displaying the locatian of 1273A Highway B2 The Z.S-acre lot is undeveloped aside from a shor1, existing driveway access. The lot slopes to the south towards the Roaring Fork River, with the general grades on the site spanning between 10-20%. The site transitions to a cliff near the bank of the Roaring Fork River, where the elevation drops roughly 35 feet. The existing access to the property exits off Highway 82 and crosses over an existing cattle guard before reaching the property. Existing gas and overhead electric run along the northern property line within a 2O-foot utility easement. An existing community water line also runs alongside the northern property line. t::, ; t't ', 'a {'1 .'- -) ' "illig:,+: i. *{ ':t dD f,fffsrilRtfifiil Proposed Gonditions The proposed structure is placed in the center of the lot and consists of a workshop garage space and an attached upstairs dwelling unit. The proposed driveway enters the property off Highway 82 to the north. The 16-foot-wide road base driveway extends onto the site at the center of the northern property line, runs south, then transitions to the west as it approaches the garage entrance. As the driveway extends past the garage, it accommodates the Firetruck Turnaround. The drive does not exceed twelve percent and is roughly 250 feet long. The stormwater runoff created by proposed conditions will be collected by a trench drain and a downspout, which will convey the stormwater to a proposed drywell located to the east of the structure. The trench drain is located at the entrance of the garage, collecting a portion of the runoff from the driveway. The roof area is collected by a single downspout that ties into the pipe network and is conveyed to the drywell. Drainage Analysis A stormwater system is proposed to collect runoff from impervious and pervious areas. The entirety of the residence will be collected by the drywell, as well as portions of the driveway. The drywell has been sized to release through an overflow at the predeveloped flow rate of a 21-year 1-hour storm event. This drainage analysis uses procedures that have been standardized by the Mile High Flood District's Urban Storm Drainage Criteria Manual, or the USDCM. Peak flows of the site have been calculated using the Rational Method to determine the impacts the proposed project has on the existing conditions, along with verifying the capacity of the proposed infrastructure. This method uses the analyzed basin's area, soil type (assumed soil type B), percentage of imperviousness, time of concentration, and the historic storm data from NOAA Atlas 14 to determine the maximum flow rate from a specified storm event. The Rational Method uses the equation below to determine the Maximum Flow Rate Q=ClA Where, - Q is the peak stormwater runoff rate, in cubic feet per second- C is a runoff coefficient of the drainage area- I is the storrn intensity, in inches per hour- A is the area of the drainage basin, in acres The Runoff Coefficient, C, is determined using table 6-5 from the USDCM. To determine the storm intensity, l, Equation 2.1 from the City of Aspen's Urban Runoff Management plan is being utilized, as it is a neighboring jurisdiction that has more similar historical data in comparison to the USDCIV. For smaller basins with a time of concentration of less than five minutes. a time of {..1.;ti;,ti liitti:t {..r.iii I i.i...',; l ti .l: .t ii .'::11 i i l:>ag<.: 2. *{ 5 concentration of five minutes is assumed - when smaller times of concentration are used in the Rational Method, the results tend to be inaccurate, as per the USDCM. The rainfall event used for this analysis is for a 1-hour Z5-year storm event. Below is a table summarizing the calculations to determine the predeveloped and developed conditions for the onsite basins. The onsite drainage conveyance structures proposed with this project have been designed to have capacityfora 1-hour 1OO-yearstorm event. The basins have been divided into sub-basins, which were analyzed for each inlet and pipe. Spreadsheets showing these calculations and supplemental information can be provided upon request from Crystal River Civil. Garfield County requires stormwater runoff from a development site to not exceed more than the historic runoff. Forthis design, CRC is proposing using historicdata from a 1-hour Z5-year event. Detention is necessary to offset the increased flows from increased impervious areas to be released at the historic rate. An analysis has been performed using the FAA Method to determine this necessary detention volume. See table below displaying the calculations for the maximum difference between the stormwater volume entering the system and volume leaving the system. 0.905 B . BsAP!

The proposed 145 cubic feet of storage within the detention meets the requirement for the historic release of a 1-hour Z5-year event and the overflow will release stormwater at a historic flow rate. Sizing for the drywell is shown in the table below. To ensure that the dryell overflow is meeting the predeveloped flow rate, the Bernoulli Equation was used to determine the size of hole to drill in the orifice plate. Below is a summary of the calculation used. This 0.92-inch orifice plate is to be installed on the daylighting overflow pipe, where it can easily be accessed for maintenance. At the over-flow of the storm system, an area of Dso = 6" Rip Rap is to be used to disperse the water and prevent erosion. i.j:'rtt, i .-,t t. 0.62 32.2 6157.32 6153.87 3.45 Sharp Edged fus2 ft fi fi Note: This calculation uses the Bernoulli Equation to determine the historic, pre- flow rate an orifice at d m outlet.
