Re: Application for Minor Subdivision
Dear Patrick:
C.R.S. § 24-65.5-103 requires that an applicant notify a mineral estate owner who either (1) is
identified as such by the county tax assessor’s records; or (2) has filed in the Clerk and Recorder a request
for notification. If such records do not identify any mineral estate owners, including their addresses of
record, “the applicant shall be deemed to have acted in good faith and shall not be subject to further
obligations….” On August 27th we conducted the following tasks for Parcel No. 239321400312:
1. We researched the Garfield County Clerk and Recorder’s index of mineral owner requests for
notification per C.R.S. § 24-65.5-103(a)(I)(B) and confirmed that no mineral owner for the
subject property has filed a request for notification; and
2. We spoke with Robyn at the Garfield County Assessor’s office and she said to their knowledge
there are no severed minerals for the subject property. We also confirmed that the Assessor’s
records for Section 21, Township 7 South, Range 88 West do not list any active or inactive
mineral owners.
This exceeds our obligations to search mineral owners under Colorado Statute. Thank you.
Sincerely,
Chad J. Lee

RE: MINOR SUBDIVISION – KRB INVESTMENTS LLC
Dear Mr. Waller:
We have reviewed the pre-application conference summary dated August 3, 2020 and are
providing the requested information regarding the legal water supply for the Minor Subdivision
proposed by KRB Investments LLC.
The 44.25 acre parcel is served by an existing well that was developed pursuant to Permit
No. 156535. This is an exempt well as defined in C.R.S. 37-92-602 that may be used in up to three
single family dwellings, an acre of irrigation and watering of domestic animals. Pursuant to
Senate Bill 20-155, attached for your ease of reference, an existing exempt well located on land
that is subsequently divided into multiple parcels maintains its exempt status as long as it only
serves one of the subdivided lots. Therefore, the existing domestic and irrigation uses on Lot 1,
and any additional future irrigation and domestic uses (accessory dwelling unit) developed on
Lot 1, will be served by the existing well under Permit No. 156535.
Lot 3 will also be served by the existing well; however, the uses on Lot 3 will be made
pursuant to a new permit specific to Lot 3 and “stacked” on the same well as Permit No. 156535.
The new well will operate within the Basalt Water Conservancy District’s Umbrella Augmentation
Plan decreed in Case No. 02CW77 as evidenced by an allotment contract issued by the District to
the Applicant. The property is within Area A of the Basalt Water Conservancy District’s service
area and the well qualifies to be included in the District’s augmentation plan. Applicant applied
to be included in the District’s augmentation plan and that application is currently in the notice
and publication period required by the terms of the decree in Case No. 02CW77. The District is
scheduled to consider and approve the application at their January 2021 meeting.
The domestic and irrigation uses on Lot 2 will be served by an off-site existing well that is
currently supplying water to an adjacent parcel under Permit No. 46260-F and Allotment Contract
No. 293 issued by the Basalt Water Conservancy District. This off-site well will provide water to
Lot 2 under a new well permit specific to Lot 2 and “stacked” on the same well as Permit No.
46260-F. The new well will operate within the Basalt Water Conservancy District’s Umbrella

Augmentation Plan decreed in Case No. 02CW77 as evidenced by an allotment contract issued by
the District to the Applicant. The property is within Area A of the Basalt Water Conservancy
District’s service area and the well qualifies to be included in the District’s augmentation plan.
Applicant applied to be included in the District’s augmentation plan and that application is
currently in the notice and publication period required by the terms of the decree in Case No.
02CW77. The District is scheduled to consider and approve the application at their January 2021
meeting.
There is no basis to believe that the Basalt Water Conservancy District will not approve
the applications for inclusion in the District’s augmentation plan and issue the requested
allotment contracts allowing for the State Engineer’s Office to issue the well permits for Lots 2 and
3. We will provide a copy of the District’s allotment contracts and the new well permits upon
receipt.
Therefore, Applicant requests that the County accept the application for minor subdivision
with the above representations and to include the following as a condition of approval that must
be met before recording of the plat: Provide the County copies of the Basalt Water Conservancy
District Allotment Contracts and Well Permits for Lots 2 and 3. Allowing the Applicant to provide
this additional information subsequent to submittal of the application is not detrimental to the
public good and is necessary to relieve the Applicant of practical difficulties and undue hardship
not a result of Applicant’s actions.
Please do not hesitate to contact me if you have any questions.
Sincerely,
BALCOMB & GREEN, P.C.

WATER SUPPLY ADEQUACY REPORT
BROADHURST MINOR SUBDIVISION
PREPARED BY
RICHARD (CHIP) FISHER, P.E.
SGM Project 2020-410.001
Introduction
SGM conducted a water supply adequacy analysis of two existing wells, per guidelines in Garfield County Land Use
and Development Code (LUDC) Section 4-203.M.1.b, as part of a land use change application to form the proposed
Broadhurst Minor Subdivision. The proposed Broadhurst Minor Subdivision will consist of Garfield County parcels
2393-2140-0312 (KRB Parcel) and 2393-2140-0113 (Broadhurst Parcel). The existing wells are listed below and
shown in the attached vicinity map (Appendix A):
1) Kevin’s Well (Permit No. 156535), KRB Parcel (2393-2140-0312), a.k.a. “Kevin’s House”
2) Rick’s Well (Permit No. 49260-F), Broadhurst Parcel (2393-2140-0113), a.k.a. “Rick’s House”
The KRB Parcel is planned to be subdivided into three lots which are shown as Lots 1 – 3 in the preliminary subdivision
plat by SurvCo, Inc., dated September 24, 2020 (Appendix B). Kevin’s Well currently supplies water to a single-family
dwelling on the KRB Parcel (Lot 1 in the proposed Broadhurst Minor Subdivision) and Rick’s Well currently supplies
water to a single-family dwelling on the Broadhurst Parcel. In the proposed Broadhurst Minor Subdivision, Kevin’s
Well will supply Lots 1 and 3 and Rick’s Well will supply Lot 2 and the Broadhurst Parcel.
Based on input from the client’s attorney at Balcomb & Green, SGM assumed that the water supply for the
Broadhurst Minor Subdivision should accommodate one single-family dwelling, one accessory dwelling unit (ADU)1,
and at least a half-acre of lawn/garden irrigation for this analysis (except for Lot 1 which is already allowed up to 1-
acre of lawn/garden under Permit No. 156535). Garfield County LUDC assesses the water demand of properties
based on single-family equivalents (SFE)2, regardless of the type of land use. An SFE value of 1 is assigned to single-
family dwellings and an SFE value of 0.75 is assigned to ADUs in order to develop a robust and conservative estimate
of water demands for future development in the Broadhurst Minor Subdivision. These assumptions are listed below
in Table 1.

2 Garfield County LUDC Section 15-101 defines Single Family Equivalent: “Measurement to compare water usage of various land uses; 1
Single-Family Equivalent equals 350 gallons of water per day, regardless of the type of use.
Physical Water Supply
Kevin’s Well (Permit No. 156535)
The physical water supply is based on 4-hour pump test data recorded by Samuelson Pump Company (Samuelson)
for each well. Kevin’s Well was installed in September 1990 by drilling into the Maroon sandstone formation at a
total depth of 360-feet. The well casing is 5-inch PVC with a screened interval from 310 to 350-feet, with a 7-inch
outer steel casing from 0 to 30-feet. The pump intake is located at a depth of 338-feet.3
Samuelson Pump Co. conducted a 4-hour pump test on August 21, 2020, using the existing pump with measurements
of drawdown and flow rate of water recorded by the pump operator. A timeseries plot of the water levels recorded
during the test is shown below in Figure 1 and the operator’s log from this test is included as Appendix C. The static
water level prior to the start of the test was 295.32-feet from the top of the casing, corresponding to 42.7-feet of
head above the intake. The well was pumped at an average flow rate of 12 gallons per minute (gpm) to a water level
of 296.5-feet corresponding to a drawdown of drawdown of 1.2-feet (2.8% change in head from static water level).
Recharge was observed for 30 minutes, with the well recovering to static water level in under one minute.

3 The operator’s log for the Parcel 1 Well Test has a typographical error regarding the pump intake, which is listed as 238’
when it was actually 338’ per the email with Raun Samuelson of Samuelson Pump Co, included with operator’s log.

from 0 to 71-feet. The pump intake is located at a depth of 438-feet.
Samuelson Pump Co. conducted a 4-hour pump test on September 25, 2020, using a Goulds 16550 test pump with
measurements of drawdown and flow rate of water recorded by the pump operator. A timeseries plot of the water
levels recorded during the test is shown below in Figure 2 and the operator’s log from this test is included as
Appendix D. The static water level prior to the start of the test was 376.56-feet from the top of the casing,
corresponding to 61.4 feet of head above the intake. The well was pumped at an average flow rate of 22-gpm to a
water level of 385.09-feet, corresponding to a drawdown of 8.5-feet (14% change in head from static water level).
Recharge was observed for 10 minutes, at which time water level had recovered to 379.10-feet, which was roughly
70% recovery of static water level.

Summary of Physical Water Supplies
Daily and annual well production rates were projected from the results of the 4-hour test for each well on the
assumption that each well is pumped for 16-hours and rested for 8-hours in a given 24-hour period. This is a
standard recommended rest period to improve operations and longevity of the pump and to allow for aquifer
recovery. Kevin’s Well supply was estimated at 12,960 gallons per day (gpd) and the annual water supply was
estimated at 15 acre-feet per year (AF/year). Rick’s Well daily water supply was estimated at 23,760 gallons per
day (gpd) and the annual water supply was estimated at 27 AF/year. Given the relatively small drawdown values
demonstrated during each well’s pump test, 2.8% for Kevin’s Well and 14% for Rick’s Well, it is reasonable to
assume each well can sustain the test pumping rates for 16-hours per day. A summary of the water supply that can
be produced by the existing wells on the KRB Investments and Broadhurst parcels is provided below in Table 2.

Existing Legal Water Supply
Kevin’s Well (Permit No. 156535)
Kevin’s Well is an exempt well, meaning that there is no requirement for water rights or augmentation to use the
well as permitted. Use under the existing permit is limited to ordinary household purposes inside three single
family dwellings, irrigation of not more than one acre of home gardens and lawns, fire protection, and the
watering of domestic animals. The permit also limits the pumping rate from the well to 15 gpm and the annual
volume produced to 1.0 AF/year.
Rick’s Well (Permit No. 49260-F)
Rick’s Well is a non-exempt well with augmentation water leased through Basalt Water Conservancy District
(BWCD) contract no. 3.3.5.293. Under the existing augmentation contract, Rick’s Well can be used to withdraw up
to 0.033-cfs (15-gpm). Allowed uses are not specified. The permit limits use of groundwater to ordinary household
purposes inside one single family dwelling, irrigation of no more than 0.5-acres of home gardens and lawns, and
limits the volume produced by the well to 1.7 AF/year.
Summary of Legal Well Supply for Broadhurst Minor Subdivision

Proposed Legal Water Supply
Lot 1 Legal Water Supply
The domestic and irrigation uses on Lot 1 will continue to be served by Kevin’s well, pursuant to Permit No.
156535. Augmentation water supplies are not required for this well because the permit maintains its exempt
status, pursuant to SB 20-155 and C.R.S. 37-92-602.
Lot 2 Legal Water Supply
The domestic and irrigation uses on Lot 2 will be served by Rick’s Well, operating a well permit specific to Lot 2
issued according to the BWCD Umbrella Augmentation Plan decreed in Case No. 02CW077. The property is within
Area A of the BWCD service and the well qualifies to be included in the BWCD augmentation plan. An application
to be included in the BWCD augmentation plan, filed by the Broadhurst Minor Subdivision applicant, is currently in
the notice and publication period required by the terms of the decree in Case No. 02CW077. Approval of the
application is expected at the BWCD January 2021 meeting. We will provide a copy of the District’s allotment
contract and the new well permit upon receipt.
Lot 3 Legal Water Supply
The domestic and irrigation uses on Lot 3 will be served by Kevin’s Well operating under a well permit specific to
Lot 3 issued according to the BWCD Umbrella Augmentation Plan decreed in Case No. 02CW077. The property is
within Area A of the BWCD service and the well qualifies to be included in the BWCD augmentation plan. An
application to be included in the BWCD augmentation plan, filed by the Broadhurst Minor Subdivision applicant, is
currently in the notice and publication period required by the terms of the decree in Case No. 02CW077. Approval
of the application is expected at the BWCD January 2021 meeting. We will provide a copy of the District’s
allotment contract and the new well permit upon receipt.
Broadhurst Parcel Legal Water Supply
The Broadhurst Parcel will continue to be served by Rick’s Well pursuant to Well Permit No. 49620-F and BWCD
Contract No. 293. There will be no changes to this legal water supply.
Water Demand Estimate
Indoor domestic demands are estimated based on the 350 gpd/SFE guidelines for Garfield County. Irrigation
demands were calculated using the modified Blaney-Criddle method in the State of Colorado’s Consumptive Use
model (StateCU), using historical climate data from nearby climate stations where precipitation and temperature
are measured with an adequate period of record. In the modified Blaney-Criddle method, evapotranspiration (ET)
is estimated for a given crop-type based on calibrated crop coefficients. ET is the amount of water that evaporates
from crop surfaces and is expelled by crops via transpiration. An irrigation water requirement (IWR) is computed as
the difference between ET and precipitation from historical climate data.
For this analysis, Denver Water high altitude pasture grass crop coefficients were used to calculated IWR for home
lawn and gardens, given that the Broadhurst Minor Subdivision sits at approximately 6,600-feet above sea level.4
Historical climate station data from 1991-2019 for Glenwood Springs #2 (USC00053359) and Aspen 1 SW
(USC00050372) were used as precipitation and temperature inputs into the StateCU model. Temperature and
precipitation data were weighted in the model based on geographic distance between the Broadhurst Minor
Subdivision site relative to the climate stations (60% for Glenwood Springs #2, 40% for Aspen 1 SW). Soil moisture
capacity was not considered. The annual unit irrigation water requirement (acre-feet water per acre of crop) for
high altitude pasture grass was estimated to be 2.09 AF/acre. A detailed table showing the modeling output and
demand calculations is included as Appendix E. A summary of the predicted water demands for each lot in the
proposed subdivision and the Broadhurst parcel is shown below in Table 4.

†Annual averages based on 350 gpd per SFE. Instantaneous demand could be higher than what is shown in this table.
‡Irrigation demand based on growing season from April 1 to October 31 (182 days).
4 Standard TR-21 crop coefficients were developed for crops at sea-level and tend to underestimate consumptive use by crops above
elevations of 6,500 feet even with elevation adjustments. Pochop crop coefficients for bluegrass cannot be adjusted for elevation and
therefore tend to underestimate demands at high elevations. The State Engineer’s Office recommends that irrigation demands for grasses
in mountainous regions at elevations above 6,500 feet are best calculated by high-altitude crop coefficients developed by Denver Water,
which were developed based on field-measurements in Park County (Colorado River Decision Support System (CRDSS) memo titled “Historic
Crop Consumptive Use Analysis Colorado River Basin” by Leonard Rice Engineers, Inc., dated October 2009).
Water Quality Analysis
Both Kevin’s Well and Rick’s Well were tested for commonly found contaminants and compared to Colorado
Department of Public Health and Environment (CDPHE) Drinking Water Standards (5 CCR 1002 Regulation 11) on
August 19 and 20, 2020. Kevin’s well was resampled for coliforms on October 6, 2020. The samples were screened
for presence of bacteria at the Snowmass Water & Sanitation District laboratory and tested for contaminants such
as volatile organic compounds and metals by SGS Laboratories. Water quality results for Kevin’s Well and Rick’s
Well are included as Appendices F and G, respectively.
Kevin’s Well (Permit No. 156535)
Results from water quality testing show that water from Kevin’s Well does not meet maximum concentration limit
(MCL) for uranium of 0.03 mg/L. Samples collected on August 20, 2020, were positive for the presence of total
coliform. Following this positive result, the well was shock-treated with chlorine, and the seals on the well head
were cleaned and re-tightened. A subsequent water quality sample collected on October 6, 2020, showed that
neither total coliform nor E. coli were detected. The positive TC result from August 20, 2020, was anomalous and
likely due to the dirt that had accumulated on the threads of the well head and contaminated the sample. There is
no indication that the source water to the well has total coliform or E. coli contamination. Table 5 below
summarizes the water quality results for this well.
Table 5. Summary of water quality results for Kevin’s Well (Permit No. 156535) in the proposed Broadhurst Subdivision. Samples were
collected on Aug. 20 and Oct. 6 by Environmental Process Control, Inc. (EPC). Total coliform and E. coli results from Oct. 6 are shown because
the Aug. 20 results were anomalous due to contamination from dirt/dust on the well head, not from the source water.

Uranium Treatment Options for Drinking Water from Kevin’s Well
The US Environmental Protection Agency (EPA) has a list of approved treatment methodologies for removal of
uranium from drinking water.5 SGM would recommend point-of-use implementation of treatment at each dwelling
served by Kevin’s Well. The two most common methods for point-of-use uranium removal are:
1) Reverse osmosis (RO) filtration with post-filtration remineralization or split-stream blending
2) Strong-base anion-exchange (SBA) resin treatment added to water softening system
RO systems typically achieve greater than 99% removal of uranium6. However, the recovery rate (flow rate of
treated water divided by the flow rate of influent water) can be as low as 50%, meaning that the demands above
would need to be doubled to serve the SFEs for the Broadhurst Minor Subdivision. Also, reverse osmosis will
drastically reduce the concentration of all dissolved solids, which can have negative consequence – water with low
total dissolved solids (TDS) increases the rate of corrosion for metal plumbing and bathroom fixtures. Either a post-
filtration remineralizing system or split-stream blending can be implemented to achieve adequate TDS values and
prevent excessive (i.e. above typical rates) corrosion.
Strong-base anion-exchange (SBA) systems can achieve greater than 95% removal of uranium.6,7 The ion-exchange
resins have to be periodically regenerated, producing a waste stream that can have increased levels of
radioactivity. Radioactive waste requires special handling and disposal with associated costs.
Both RO and SBA will effectively treat water from Kevin’s well to below the MCL of 0.03 mg/L and both methods
have downsides, such as high maintenance requirements. The applicant and future homebuilders in the
Broadhurst Minor Subdivision should consult a drinking water treatment professional (i.e. engineer) for detailed
system design that will balance user needs and maintenance costs. See Appendix H for more detailed information
about RO and ion-exchange technologies.

(AWWA). 1994.; pp 214-227.
Rick’s Well (Permit No. 49260-F)
Rick’s Well meets all parameters that were tested and there are no water quality concerns at this time. Table 6
below summarizes the water quality results for this well.

Fire Suppression Storage Considerations
Per section 7-109 B. of the Garfield County LUDC, fire flow and fire suppression storage requirements for all new
development in the proposed subdivision should be designed and installed based on guidance from the Fire
Marshall at Carbondale & Rural Fire Protection District. No requirements for fire suppression storage are stipulated
by the Carbondale & Rural Fire Protection District. The property owner can choose to install a fire suppression
storage tank at their discretion according to National Fire Protection Association (NFPA) Code 1142.
Groundwater Resource Considerations
The increased demand placed on these wells will result in increased depletions to local groundwater resources,
which are hydrologically connected to the Roaring Fork River. However, the projected demands are not likely to
negatively impact nearby wells in the vicinity of the proposed Broadhurst Minor Subdivision. Any lagged depletions
to the Roaring Fork River will be augmented through Basalt Water Conservancy District contracts as part of the
recommended permitting for the proposed uses in the Broadhurst Minor Subdivision.
Conclusions and Recommendations
Kevin’s Well (Permit No. 156535)
Kevin’s Well (Permit No. 156535) is physically able to supply water to Lots 1 and 3 of the proposed Broadhurst
Minor Subdivision. The pumping test demonstrated that 12-gpm is likely sustainable for a 16-hour pumping period
per 24-hours, given that the drawdown during a 4-hour test was relatively small (1.2-feet drawn down from 42.7-
feet of head above the pump intake). At this pumping rate, demands for domestic and irrigation for Lot 1 and Lot 3
will be adequately served. However, we recommend that Garfield County Community Development (County)
impose the following conditions of approval on recordation of the final plat:
1) Applicant will provide the County with a copy of the BWCD Contract and Well Permits for Lot 3
2) Evidence that the recommended treatment for uranium has been installed in the existing residence on
Lot 1
Allowing the Applicant to provide this additional information after the land use change submittal for the
Broadhurst Minor Subdivision is not detrimental to the public good and is necessary to relieve the Applicant of
practical difficulties and undue hardship not resulting from the Applicant’s actions. Water quality for Kevin’s Well
does not meet minimum drinking water standards, so we recommend the following for each dwelling (existing and
future) supplied by this well:
3) Treat for uranium at each dwelling with a point-of-use system with one of the EPA-approved methods
described previously in this report
Rick’s Well (Permit No. 49260-F)
Rick’s Well is physically able to supply water to Lot 2 of the proposed Broadhurst Minor Subdivision and the
existing Broadhurst Parcel. The pumping test demonstrated that 22-gpm is likely sustainable for a 16-hour
pumping period per 24-hours, given that the drawdown during a 4-hour test was relatively small (8.5-feet drawn
down from 61.4-feet of head above the pump intake). At this pumping rate, demands for domestic and irrigation
for Lot 2 and the Broadhurst Parcel will be adequately served. However, the existing legal water supply is
insufficient. However, we recommend that the County the following conditions of approval on recordation of the
final plat:
1) Applicant will provide the County with a copy of the BWCD Contract and Well Permits for Lot 2
Allowing the Applicant to provide this additional information after the land use change submittal for the
Broadhurst Minor Subdivision is not detrimental to the public good and is necessary to relieve the Applicant of
practical difficulties and undue hardship not resulting from the Applicant’s actions.

Great, thanks!
And what about the recovery? Did the well not rest for long enough when the pump test was started?

The well depth is 340', Pump setting should read 338', The water level should read 295.32' and all of the drawdown
readings are 295 to 296

Thanks for sending this over Raun.

I’d like to confirm a few things with you for the Well Test log at 1435 CR 107 (Kevin’s House) – did the well really have
100-ft of drawdown between minute 3 and minute 4 first few and then almost no drawdown for the rest of the 4-hour test?
Also, can you confirm the depths on the pump and the static water level? Seems like the static water level was probably
295.32 instead of 195.32? The way it’s written on the log (pump intake at 238’) the water level was drawn down below the
pump?
Finally, assuming that the static water level was actually 295.32, and not 195.32, did the well really recover to a higher
level than static?
Thanks!

The amount of total dissolved solids (TDS) rejected by the membrane is expressed as a
percentage. For example, a 98.5% rejection rate means that 98.5% of total dissolved
solids do not pass through the membrane. To calculate the % rejection, use the
following formula:
% Rejection = [(Feed TDS – Product TDS) / Feed TDS] x 100
Example:
98.5% = [(550-8.25)/550] x 100
NOTE: ALL TDS FIGURES MUST BE EXPRESSED IN THE SAME UNITS,
TYPICALLY PARTS PER MILLION (PPM) OR MILLIGRAMS PER LITER (MG/L).
LT-Series reverse osmosis systems are designed to reject up to 98.5% NaCl, unless
computer projections have been provided or stated otherwise.
The amount of permeate water recovered for use is expressed as a percentage. To
calculate % recovery, use the following formula:
% Recovery = (Product Water Flow Rate / Feed Water Flow Rate) x 100
Example:
28% = (0.14/0.50) x 100
NOTE: ALL FLOW RATES MUST BE EXPRESSED IN THE SAME UNITS,
TYPICALLY GALLONS PER MINUTE (GPM).
SYSTEM INSTALLATION AND START-UP PROCEDURES
1. Inspect the system for any damage that could have occurred during shipment.
Although our systems have been individually inspected, complete a quick inspection
of the fittings, tubing and other components.
2. Please provide a reasonable amount of space for installation and leave 6 inches of
space below the filter housings for ease of maintenance.

LT – Series User’s Manual
MKTF-210 06/12
NOTE: THE REVERSE OSMOSIS SYSTEM SHOULD BE INSTALLED
INDOORS AND IT IS SUGGESTED THAT IT NOT BE IN DIRECT SUNLIGHT OR
EXTREME COLD.
3. Connect the 3/8” or 1/4” tube fitting to an incoming water source. The minimum
water pressure should be at least 30 psi. The system’s minimum operating pressure
is 80 PSI, but the optimum operating pressure is 100 psi.
NOTE: DO NOT OPERATE AT A PRESSURE EXCEEDING 125 PSI. The
operating pressure can be increased on the face of the booster pump by turning the
hex screw clockwise.
4. Connect the concentrate 1/4” tubing (waste) line to drain.
5. Plug the booster pump transformer into a power supply of 110 or 220 volts.
6. This system has been designed with an auto-flush restrictor. This restrictor
automatically flushes the reverse osmosis system for 30 seconds every time it starts
up and once every hour when the system is producing water.
NOTE: THE TANK PRESSURE SWITCH WILL SHUT THE SYSTEM OFF
AUTOMATICALLY WHEN THE BLADDER TANK IS FULL.
7. The sediment filter and carbon must be serviced regularly for optimal performance.
The filters and water quality should be checked every two weeks minimum.
8. Dispose of the product water until the conductivity of the product water reaches your
desired level. Use any TDS or Conductivity meter to monitor the product water

OPERATING DO’s AND DON’Ts
DO:
• Change the cartridge filters regularly
• Monitor the system and keep a daily log
• Run the system as much as possible on a continuous basis.
• Always feed the pump with filtered water.
DON’T
• Permit chlorine to enter or be present in the feed water.
• Shut down the system for extended periods.
• Operate the system with insufficient feed flow.
• Operate the pump dry.
MAINTENANCE PROCEDURES
1. Periodically observe the quality and quantity of product water from the system.
NOTE: CHECK THE FEED WATER PRESSURE GOING INTO THE
REVERSE OSMOSIS MEMBRANE, A SIGNIFICANT DROP IN PRESSURE
COULD INDICATE A FOULED PRE-FILTER.
2. A 20% increase in TDS when checking the permeate water indicates possible
membrane damage, and the membrane may need to be replaced.
3. It is suggested that a hand held TDS digital meter is used once per week to monitor
the water quality.
19
LT – Series User’s Manual
MKTF-210 06/12
NOTE: IF THE TDS OF THE FEED WATER EXCEEDS 1000 PPM OF
NACL, A LARGER FLOW RESTRICTOR SHOULD BE USED TO EXTEND THE
MEMBRANE LIFE.
4. It is important to maintain and/or replace the carbon block regularly since the Thin
Film Composite membranes are chlorine sensitive. Irreversible damage will occur
with any chlorine present in the feed water. For additional information, please
review the manufacturer’s membrane specification sheets.
5. The product line has a one way check valve installed. The check valve should be
checked regularly and replaced if it is not properly sealing.
6. Keep the feed water temperature above 4°C (36°F).
NOTE: EXTREMELY COLD FEED WATER WILL LOWER THE PRODUCT
WATER OUTPUT AND INCREASE PUMP PRESSURE.

MEMBRANE
Replacing membranes in the pressure vessels is an easy process if you have the
proper information and tools at hand. Please refer to the following instructions when
removing and replacing membrane elements:
WARNING: ALL PRESSURE GAUGES MUST READ ZERO BEFORE
PROCEEDING. BEFORE ATTEMPTING
SYSTEM AND BLEED ALL WATER PRESSURE FROM
1. Remove the end caps from the top of the membrane housings. This is
removing the white snap ring of the membrane
2. Remove the membrane bag
box.
WEAR GLOVES FOR
CONTAMINATE THE MEMBRANE.
3. Cut the bag open as close as possible to the seal at the end of the bag, so the
bag may be re-used if necessary.
4. Make sure that all parts are clean and free fr
permeate tube for nicks or cuts. Replace the O
5. Flow directions should be observed for installation of each element into each
housing.
As time progresses, the efficiency of the membrane will be reduced. In general, the salt
rejection does not change significantly until two or three years after installation when
operated on properly pretreated feed water. The permeate flow rate will begin to decline
slightly after one year of operation, but can be extended with diligent flushing and
cleaning of the system. A high pH and/or precipitation of hardness can cause
premature loss in rejection.
REPLACING THE MEMBRANE ELEMENT:
WARNING: THE BRINE SEAL MUST BE IN THE SAME POSITION FOR
EACH MEMBRANE ELEMENT HOUSING, SO MARK EACH HOUSING PRIOR TO
REMOVING THE MEMBRANE

MKTF-210 06/12
THAT PROTRUDES ON ONE SIDE OF THE MEMBRANE AND IS ALWAYS ON THE
FEED SIDE OF THE MEMBRANE ELEMENT.
1. Remove one membrane element at a time from the membrane element
housings, from the top of the housing. Long nose pliers may be necessary to pull
the old membrane element out of the membrane element housing.
2. Lubricate the brine seal with non petroleum based lubricant, Silicone DC 111.
3. Install the brine seal side of the membrane element first. When the housings
have a direction of flow from bottom to top, the brine seal should be located at
the bottom of the housing.
4. At a slight angle, insert the membrane while slightly rotating the element being
careful not to tear or flip the brine seal. A slow twisting motion should be used to
insert the membrane element, to ensure the brine seal stays in place. Re-lube
the brine seal if necessary.
5. With a smooth and constant motion, push the membrane element into the
housing so the brine seal enters the housing without coming out of the brine seal
groove.
6. Re-install the end caps by gently twisting the end cap while pushing it onto the
housing. Ensure that you do not pinch or fatigue any O-rings while re-installing
the end plug. Push the end plug on until the outer diameter of the plug is flush
with the outer diameter of the membrane housing.
7. Insert the snap ring until it is fully seated. Install the locking clip if available.
8. Reconnect any fittings that may have been disconnected when the membrane
element housings were disassembled.
9. To start-up the system, please refer to the Start-Up section of this manual. (See
Page 6)
CAUTION: WET MEMBRANES ARE SHIPPED IN A PRESERVATIVE
SOLUTION. THE MEMBRANES MUST BE FLUSHED FOR AT LEAST 1 HOUR TO
REMOVE THE PRESERVATIVE FROM THE MEMBRANE. DISCARD ALL OF THE

PREPARING UNIT FOR STORAGE OR SHIPMENT
Prior to shipping or storing your system, the system should be cleaned with an
appropriate cleaner, flushed with water and protected from biological attack with an
appropriate solution for membrane elements. The membrane housing(s) and plumbing
lines of the system must be completely drained. Any water remaining in the plumbing of
a system may freeze, causing serious damage.
Preparing system for storage:
1. Totally immerse the elements in the membrane housing in a solution of 2 %
Memstor, venting the air outside of the pressure vessels. Use the overflow
technique: circulate the Memstor solution in such a way that the remaining air in
the system is minimized after the recirculation is completed. After the pressure
vessel is filled, the Memstor solution should be allowed to overflow through an
opening located higher than the upper end of the highest pressure vessel being
filled.
2. Separate the preservation solution from the air outside. Any contact with oxygen
will oxidize the Memstor.
3. Check the pH once a week. When the pH becomes 3 or lower, change the
preservation solution.
4. Repeat this process at least once a month.
During the shutdown period, the plant must be kept frost-free, or the temperature must
not exceed 113°F (45°C).
Preparing unit for shipment:
5. Disconnect the inlet, concentrate, pre-filter, and permeate plumbing.
6. Drain all water from the pre-filter cartridge housings by unscrewing the housings,
removing the pre-filter cartridges, and drain the water from the housings.
7. Disconnect the tubing from the connectors on the permeate and concentrate
inlets and outlets.
8. Allow the system to drain for a minimum of eight hours or until the opened ports
quit dripping.
9. After draining is complete, reconnect all of the plumbing.

ABNORMAL PERMEATE FLOW
Permeate flow should be within 20% of the rated production, after correcting the feed
water temperatures above or below 77°F. Check your permeate flow meter to
determine the permeate flow rate.
NOTE: TO DETERMINE THE TEMPERATURE CORRECTION FACTOR,
LOCATE THE TEMPERATURE CORRECTION TABLE IN THIS USER’S MANUAL
AND FOLLOW THE DIRECTIONS

MKTF-210 06/12
TEMPERATURE CORRECTION FACTORS FOR MEMBRANE
Find the temperature correction factor (TCF) from the table below. Divide the rated
permeate flow at 77°F by the temperature correction factor. The result is the permeate
flow at the desired temperature. (See example on the next page)
26
LT – Series User’s Manual
MKTF-210 06/12
If a system is rated to produce 5 gpm of permeate water @ 77˚ F, the same system will
produce more water at a higher temperature. It will also produce less water at a lower
temperature. Use the temperature correction table to obtain the correct flow.
Example:
5 gpm @ 59˚ F (5÷1.42=3.52 gpm)
5 gpm @ 77˚ F (5÷1=5 gpm)
5 gpm @ 84˚ F (5÷0.89=5.62 gpm)

Section 1IntroductionAG 1, AG MP-1 and AG 2 resins are strongly basicanion exchangers. They are capable of exchanginganions of acidic, basic, and neutral salts, and ampholyteson the basic side of their pI. Strong anion exchangeresins are used for sample preparation, enzyme assays,metal separations, and peptide, protein, and nucleic acidseparations.Section 2Technical DescriptionStrongly basic anion exchange resins are availableas Analytical Grade AG 1 and AG 2 resins, AG MP-1macroporous resin, and Biotechnology Grade AG 1resin. The Analytical Grade AG 1, AG MP-1 and AG 2resins have been exhaustively sized, purified, and con-verted to make them suitable for accurate, reproducibleanalytical techniques. Biotechnology Grade AG 1 resinis analytical grade resin which is certified to contain lessthan 100 microorganisms per gram of resin.1LIT212C 6/17/98 12:25 PM Page 1
exclusion limits in water for resins of various crosslink-ages.Table 1. Approximate Molecular Weight ExclusionLimits for Ion Exchange Resins in WaterPercent Approximate MW Exclusion LimitCrosslinking for Globular Molecules2% 2,7004% 1,4008% 1,00010% 80012%400AG 2 resin is similar to AG 1 resin, but is slightlyless basic and slightly less resistant to oxidation due todifferences in the structure of the quaternary functionalgroup. It offers advantages in certain applications. Forexample, it is capable of separating sugars, sugar alco-hols, and glycosides using a step gradient and boratebuffers without isomerizing some sugars, as AG 1 resintends to do.3AG 1 and AG 2 resins are strongly basic anionexchangers with quaternary ammonium functionalgroups attached to the styrene divinylbenzene copoly-mer lattice. The amount of resin crosslinkage determinesthe bead pore size. A resin with a lower percentage ofcrosslinkage has a more open structure permeable tohigher molecular weight substances than a highlycrosslinked resin. It also has a lower physical resistanceto shrinking and swelling, so that it absorbs more waterand swells to a larger wet diameter than a highlycrosslinked resin of equivalent dry diameter. For exam-ple, the lower crosslinked resins, particularly AG 1-X22% crosslinked resin, are useful for the sorption andfractionation of relatively high molecular weight sub-stances such as peptides, ribo- and deoxyribo-nucleotides, and uranium. The higher crosslinked resins,particularly AG 1-X8 8% crosslinked resin, are used forsorption, exchange, and separation of low molecularweight inorganic anions, and in applications such ascyclic nucleotide assays and fractionation of organicacids.

With anion exchange resins such as AG 1 and5Each AG 1 resin is supplied in the chloride form.Selected resins are available in the acetate, formate, andhydroxide form. These ionic forms may be consideredmore activated forms than the chloride form, as may bededuced from the order of selectivity information givenin Tables 2 and 3. AG 1 resins purchased in the moreactive forms may be converted to any other form. Thechloride ion, because of its higher selectivity for theresin, is relatively difficult to replace with formate,acetate, hydroxide, or fluoride. Thus, if various ionicforms are to be used, the formate or acetate forms pro-vide flexibility and convenience (see Table 3). Formateand acetate forms may be used to separate most lowmolecular weight biological compounds, such asnucleotides, hormones, peptides, and carboxylic acids.AG MP-1 resin is the macroporous equivalent of AG 1resin. Its effective surface area approximates 23 squaremeters per dry gram, 20% porosity.The physical properties of the resins are listed inTable 2. The anion exchange resins are thermally stableand resistant to solvents (alcohols, hydrocarbons, etc.),reducing agents, and oxidizing agents.4LIT212C 6/17/98 12:25 PM Page 4

In the chloride form of AG 1, AG MP-1,and AG 2 resin, the counterion on the resin is Cl-. Aresin can be converted from one ionic form to another.Usually the resin is used in an ionic form with a lowerselectivity for the functional group than the sample ionsto be exchanged. The sample ions are then exchangedonto the resin when introduced, and can be eluted byintroducing an ion with higher affinity for the resin or ahigh concentration of an ion with equivalent or loweraffinity. Table 3 shows the relative selectivity of variouscounterions. In general, the lower the selectivity of thecounterion, the more readily it exchanges for another ionof like charge. The order of selectivity can also be usedto estimate the effectiveness for different ions as eluants,with the most highly selective being the most efficient.Finally, the order of selectivity can be used to estimatethe difficulty of converting the resin from one form toanother. Conversion from a highly selected to a lesshighly selected form requires an excess of the new ion.6LIT212C 6/17/98 12:25 PM Page 6

using 20 bed volumes of 1 N NaOH. The resin has avery low selectivity for hydroxide, making the conver-sion to the formate form relatively simple (2 bed vol-umes of 1 N formic acid). Another conversion method isto first convert to an ionic form of intermediate selectiv-ity. When converting from the chloride form (relativeselectivity 22) to the hydroxide form (relative selectivity1), the resin can first be converted to the bicarbonateform (relative selectivity 6.0).The easiest method to test for completeness of con-version depends on the particular conversion.Conversion is complete when the first ion is no longerdetected in the effluent. In many cases, this can be moni-tored by pH or by simple qualitative tests. When conver-sion is complete, the resin should be rinsed with deion-ized water, then with starting buffer, until a stable pH isobtained. The resin is then equilibrated to the desiredstarting conditions.13Conversions to ionic forms not listed in Table 5 canbe achieved using the information supplied in Table 3,which lists relative selectivities of various counterionsfor AG 1, AG MP-1, and AG 2 resin. To convert a resinto an ionic form with a higher selectivity, wash the resinwith 2-5 bed volumes of a 1 M solution of the desiredcounterion. For conversion to an ionic form with a lowerrelative selectivity for the resin, the necessary volume ofcounterion solution will depend on the difference inselectivity. As a general rule, use 1 bed volume of 1 Mcounterion solution for each unit difference in relativeselectivity. For example, converting AG 1-X8 resinfrom the formate form (relative selectivity 4.6) to thehydroxide form (relative selectivity 1.0) would require4-5 bed volumes of 1 M NaOH.In some cases, it is more economical and more effi-cient to go through an intermediate counterion whenconverting to a counterion of much lower selectivity.One example of this is the conversion of AG 1-X8 resinfrom the chloride form (relative selectivity 22) to theformate form (relative selectivity 4.6). The resin is firstconverted to the hydroxide form (relative selectivity 1.0)12LIT212C 6/17/98 12:25 PM Page 12
5.2 Column MethodThe column method involves pouring a column withthe resin and passing the sample through to achieve theseparation. Particle size will determine the flow rate,which will affect the separation. The resin should be inthe correct ionic form and equilibrated prior to addingthe sample.1. Calculate the amount of resin required based on theexpected resin capacity and sample concentration. Ifthe sample ionic concentration is unknown, beginwith 5 grams of resin for 100 ml of sample, and thenoptimize the volumes after looking at the results ofthe first separation.2. Insure that the resin is in the proper ionic form toallow the sample ions to be exchanged onto theresin. If conversion of the resin into another ionicform is necessary, use the guidelines described forresin conversion (see Table 5).3. Prepare the initial buffer so that the pH and ionicconcentration will allow the sample ions to be15Section 5Instructions for UseAG 1 and AG MP-1 resins may be used in a batchmethod or a column method. The batch method consistsof adding the resin directly to the sample and stirring.The column method requires packing a column withresin, and passing the sample through.5.1 Batch MethodThe batch method is performed by adding the resindirectly into the sample and stirring. The resin should bein the correct ionic form prior to beginning.1. Weigh out about 5 grams of resin for every 100 mlof sample. For larger scale applications or when anexact amount of resin is needed, calculate the resinvolume based on the resin capacity.2. Add resin to the sample and stir or shake gently for1 hour.3. Filter or decant the sample from the resin.14LIT212C 6/17/98 12:25 PM Page 14
tions of starting eluant, being very careful to rinsedown the sides of the column and to avoid stirringup the bed. Drain each portion to the level of theresin bed before the next portion is added. Neverallow the liquid level to drain below the top of theresin bed sample.7. The actual flow rate that is used will depend uponthe application, the resin, and the column cross-sec-tion. To obtain flow rates for any given size column,multiply the suggested flow rates in Table 6 by thecolumn cross-sectional area. Table 6 gives typicalflow rates of analytical grade resins.8. If an anion free solution is the goal, collect the efflu-ent. If the concentrated anions are of interest, allowall of the sample to pass through the column, thenelute the anions off the resin with a solution contain-ing a counterion of higher selectivity than the boundanion.17exchanged onto the column. For unknown solutions,use deionized water.4. Slurry and pour the resin into the column.Equilibrate the resin in the initial buffer using 3 bedvolumes of buffer. Poorly equilibrated resin will notgive reproducible results. Alternatively, equilibra-tion can be done by the batch technique, prior topouring the column. First, convert the resin to theappropriate form, then suspend it in the startingbuffer. Check the pH with a pH meter while stirringcontinuously. Adjust the pH by adding acid or basedropwise to the buffer until the desired pH isobtained. Then transfer the resin to the column, andpass 1 bed volume of the starting buffer through thecolumn.5. Slurry the resin in the initial buffer and pour the col-umn. Allow excess buffer to pass through the col-umn, leaving enough buffer to just cover the top ofthe resin bed.6. Apply the sample dropwise to the top of the columnwithout disturbing the resin bed. Drain the sampleinto the top of the bed and apply several small por-16LIT212C 6/17/98 12:25 PM Page 16

When the level of 9 N HCl has reached the top ofthe resin bed, either shut the screw clamp, or add 2ml of sample (0.2 meq of each ion).6. Do not allow air into the resin bed because air maycause channeling with uneven flow of subsequentsolutions.7. After the sample has soaked into the resin bed, addapproximately 20 ml of 9 N HCl.8. Begin collecting 5 ml aliquots.9. The color of the eluant should intensify and then theeluant should become nearly colorless in the third orfourth aliquot.10. Continue elution using 20 ml of 5 N HCl, and then20 ml of 0.5 N HCl, in the manner described above.11. In each case, 5 to 10 ml more of the eluant may beadded if the eluant is still strongly colored after 20ml of acid has soaked into the resin bed.20LIT212C 6/17/98 12:25 PM Page 20

sewer services to this area, so criterion 4 above is met. As such, Garfield County has sole
authority for the administration and enforcement for the design of OWTSs for the proposed
subdivision lots and design of each system will be governed by the County’s OWTS
Regulations.

shown on proposed subdivision Lot 2. There are two wells to be utilized for water, one is in
proposed subdivision Lot 1 and the other is in the NW1/4 NW1/4 SE1/4 of Section 21, T7S,
R88W of the 6th P.M., directly north of proposed subdivision Lot 2. The existing structures
and well locations are shown on Figure 1, which can be found in the Appendix.
4.2 Local Public Health Agency Records.
Existing Sewage Disposal Systems: According to County Public Records there have been
two existing sewage disposal systems permitted for the existing property. One is an ISDS
approved for a 3 bedroom residence dated 7/09/1990. It is believed this system provides
sewage treatment for the existing residence at 1434 County Road 107, Carbondale,
Colorado. The other system is an approved ISDS associated with a prefabricated steel
building having a ½ bath and loft, dated 4/25/2016. Both permits have the address of 1434
County Road 107, Carbondale, Colorado.
4.3 Public Site Information.
Topography and Soil Data: Grade percentages and soil data for the subject property were
downloaded from the National Resource Conservation Services (NRCS) Soil Web Site.
The data indicates there are two major soil units within the proposed minor subdivision, soil
unit 35 and soil unit 106.
Soil unit 35 consists of Empedrado loam, which has grades between 6 to 12 percent. In
addition, NRCS rates this soils unit as having 33.6% silts, 35.4% sands and 31% clays with
a depth to the most restrictive layer as being greater than 6.5 feet. Proposed minor
subdivision Lot 1 contains approximately 20.110 acres, Lot 2 approximately 4.224 acres
and NRCS soil unit 35 is not found in Lot 3.
Soil unit 106 consist of Tridell-Brownsto stony sandy loams, which has grades between 12
to 50 percent. In addition, NRCS rates this soil unit as having 9.0% silts, 83.5% sands and
7.5% clays with a depth to the most restrictive layer being greater than 6.5 feet. In
proposed Lot 1 of the minor subdivision there is approximately 4.135 acres of NRCS soil
unit 106, 5.776 acres in proposed Lot 2 and 10.000 acres in proposed Lot 3.
OWTS can be installed on slopes up to 30 percent (3.3H:1V) without having to be designed
by a professional engineer registered and licensed to practice in the State of Colorado. Per
the NRCS soil unit data, there may be some areas within proposed minor subdivision Lots
1, 2 and 3 that may be in excess of the 30 percent criterion and would require engineered
design.
4.4 Location of Physical Features Requiring Setbacks per Table 7-1 of the County’s OWTS
Regulations.
The location of known existing features that require setbacks per Table 7-1 of the County’s
OWTS Regulations are shown on Figure 1. It is not known at this time where proposed
features will be located that will require setbacks in accordance with Table 7-1, but there is
ample acreage available for each proposed minor subdivision lot to meet future setback
requirements due to installation of future features.
4.5 Preliminary STA size estimate.
The preliminary STA size estimate is based on:

· Single-family residential design flows.
· And determination of the long term acceptance rate (LTAR) associated with the
infiltrative soil layer.
The following table shows residential design flows for single-family residents.
TABLE 1 – RESIDENTIAL DESIGN FLOWS FOR SINGLE -FAMILY RESIDENCE
No. of Bedrooms Occupancy (No. of
Persons)
Wastewater Flow
per Person (gpd)
Design Flow

2 4 75 300
3 6 75 450
4 7 75 525
5 8 75 600
6 9 75 675
Add 75 gpd for each occupant over 9, max occupant count = 26.
Total occupant count is reduced by additional auxiliary buildings
and fixture types per Table 6-2 of the County’s OWTS
Regulations. Maximum wastewater generation design flow =
2,000 gpd, unless criteria in 2 and 3 under Authority can be met
and demonstrated.
Determination of the required square footage for the STA is dependent on the residential
design flow divided by the infiltrative soils LTAR. The LTAR for use in the preliminary STA
size estimate is found by using the United States Department of Agriculture’s (USDA)
textural triangle in conjunction with percentages of silt, sand and clay found in the NRCS
soils data. On the triangle, percentages for silt, sand and clay are plotted. The point where
the three cross is the USDA soil texture, which relates to the soil type and determines the
LTAR.
For NRCS soil unit 35, the soil texture is a clay loam, which could be a soil type 3 or 3A. A
soil type 3 has a LTAR of 0.35 gpd/ft2 and soil type 3A has a LTAR of 0.30 gpd/ft2. To break
the tie for actual design, more information is required, which is collected during the detailed
soil investigation. However, for the preliminary STA size estimate, the more conservative
LTAR associated with soil type 3A is used, 0.30 gpd/ft2. It should be mentioned that a soil
type 3A requires design by a professional engineer registered and licensed to practice in
the State of Colorado.
For NRCS soil unit 106, the soil texture is a loamy clay, which has a soil type classification
of 5. Soil type 5 has a LTAR OF 0.10 gpd/ft2 and also requires design by a professional
engineer registered and licensed to practice in the State of Colorado.
Using the LTAR’s determined for NRCS soil units 35 and 106, the following table reflects
the estimated STA size for residences up to a count of 6 bedrooms.

The estimated STA size is without adjustment factors being applied. Garfield County’s
OWTS Regulations allow for adjustment factors to be applied based on the method of effluent
application to the STA and the distribution media used in the STA.
The method of effluent application to the STA can be by gravity, dosed (siphon or pumped)
and pressure dosed. Size adjustment factors for method of effluent application are shown in
the following table.

The maximum required square footage required to install a STA for the proposed subdivision
lots would be determined using gravity for the method of effluent application to a soil
absorption bed with a category 1 distribution media. The following table shows the maximum
required square footage to install a STA in NRCS soil unit 35, based on the number of
residential bedrooms and using the most stringent adjustment factors.

The actual site area required to install the STA will be the direct result of the OWTS design,
which is based on:
· The actual number of bedrooms for the residential structure.
· The type of absorption area used; trench or bed.
· The method of effluent application to the absorption area; gravity, dosed (siphon or
pumped) or pressure dosed.
· The type of distribution media used in the absorption area; category 1, category 2 or
category 3.
· Or utilization of a higher level treatment system.
However, to keep the perspective in line with the scope of this report, which is to determine
the feasibility to install a STA, the maximum required site area will be determined using the
following design criteria:
· The absorption area is a bed with a maximum width of 12 feet and at least 6 feet
between bed sidewalls.
· The absorption media is category 1.
· Effluent application is by gravity.
· Maximum distribution lateral length is 100 feet.
· Distribution box is located at the center of the lateral.

The above tables were developed using the most stringent adjustment factors for sizing a
STA and indicates that it is feasible to install an OWTS in NRCS soil unit 35 for up to at least
a 6 bedroom residence. The tables indicate that for NRCS soil unit 106 it is bordering
whether it is feasible or not feasible for construction of a 2 bedroom residence. Anything
larger does not appear to be feasible for installation of an OWTS when using the most
stringent adjustment factors.
However, using less stringent adjustment factors in NRCS soil unit 106, i.e. a trench with an
application method of pressure dosing, in addition to chambers results in a STA having the
following sizes.

required site area can be further reduced by treating wastewater to at least treatment level 2,
TL2.
Lastly, it should be noted that all of the above tables represent STA sizes based on data
from the NRCS “Web Soil Survey” site, which is useful in determining the feasibility of
installing an OWTS prior to actually collecting on-site field data. However, it has been
SGM’s experience that actual required site areas for the installation of a STA is reduced
when using data developed from the detailed site soil investigation, which is required for
actual design of an OWTS.

Description
Silt as a soil separate consists of mineral soil particles that are 0.002 to 0.05
millimeter in diameter. In the database, the estimated silt content of each soil
layer is given as a percentage, by weight, of the soil material that is less than 2
millimeters in diameter.
The content of sand, silt, and clay affects the physical behavior of a soil. Particle
size is important for engineering and agronomic interpretations, for determination
of soil hydrologic qualities, and for soil classification
For each soil layer, this attribute is actually recorded as three separate values in
the database. A low value and a high value indicate the range of this attribute for
the soil component. A "representative" value indicates the expected value of this
attribute for the component. For this soil property, only the representative value is
used.

Aggregation is the process by which a set of component attribute values is
reduced to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is
either some type of soil or some nonsoil entity, e.g., rock outcrop. For the
attribute being aggregated, the first step of the aggregation process is to derive
one attribute value for each of a map unit's components. From this set of
component attributes, the next step of the aggregation process derives a single
value that represents the map unit as a whole. Once a single value for each map
unit is derived, a thematic map for soil map units can be rendered. Aggregation
must be done because, on any soil map, map units are delineated but
components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding
component typically makes up approximately 60% of the map unit. Percent
composition is a critical factor in some, but not all, aggregation methods.
The aggregation method "Dominant Component" returns the attribute value
associated with the component with the highest percent composition in the map
unit. If more than one component shares the highest percent composition, the
corresponding "tie-break" rule determines which value should be returned. The
"tie-break" rule indicates whether the lower or higher attribute value should be
returned in the case of a percent composition tie. The result returned by this
aggregation method may or may not represent the dominant condition throughout
the map unit.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. If no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Tie-break Rule: Higher
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.
Interpret Nulls as Zero: No
This option indicates if a null value for a component should be converted to zero
before aggregation occurs. This will be done only if a map unit has at least one
component where this value is not null.

For an attribute of a soil horizon, a depth qualification must be specified. In most
cases it is probably most appropriate to specify a fixed depth range, either in
centimeters or inches. The Bottom Depth must be greater than the Top Depth,
and the Top Depth can be greater than zero. The choice of "inches" or
"centimeters" only applies to the depth of soil to be evaluated. It has no influence
on the units of measure the data are presented in.
When "Surface Layer" is specified as the depth qualifier, only the surface layer or
horizon is considered when deriving a value for a component, but keep in mind
that the thickness of the surface layer varies from component to component.
When "All Layers" is specified as the depth qualifier, all layers recorded for a
component are considered when deriving the value for that component.
Whenever more than one layer or horizon is considered when deriving a value
for a component, and the attribute being aggregated is a numeric attribute, a
weighted average value is returned, where the weighting factor is the layer or
horizon thickness.

Description
Sand as a soil separate consists of mineral soil particles that are 0.05 millimeter
to 2 millimeters in diameter. In the database, the estimated sand content of each
soil layer is given as a percentage, by weight, of the soil material that is less than
2 millimeters in diameter. The content of sand, silt, and clay affects the physical
behavior of a soil. Particle size is important for engineering and agronomic
interpretations, for determination of soil hydrologic qualities, and for soil
classification.
For each soil layer, this attribute is actually recorded as three separate values in
the database. A low value and a high value indicate the range of this attribute for
the soil component. A "representative" value indicates the expected value of this
attribute for the component. For this soil property, only the representative value is
used.

Aggregation is the process by which a set of component attribute values is
reduced to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is
either some type of soil or some nonsoil entity, e.g., rock outcrop. For the
attribute being aggregated, the first step of the aggregation process is to derive
one attribute value for each of a map unit's components. From this set of
component attributes, the next step of the aggregation process derives a single
value that represents the map unit as a whole. Once a single value for each map
unit is derived, a thematic map for soil map units can be rendered. Aggregation
must be done because, on any soil map, map units are delineated but
components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding
component typically makes up approximately 60% of the map unit. Percent
composition is a critical factor in some, but not all, aggregation methods.
The aggregation method "Dominant Component" returns the attribute value
associated with the component with the highest percent composition in the map
unit. If more than one component shares the highest percent composition, the
corresponding "tie-break" rule determines which value should be returned. The
"tie-break" rule indicates whether the lower or higher attribute value should be
returned in the case of a percent composition tie. The result returned by this
aggregation method may or may not represent the dominant condition throughout
the map unit.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. If no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Tie-break Rule: Higher
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.
Interpret Nulls as Zero: No
This option indicates if a null value for a component should be converted to zero
before aggregation occurs. This will be done only if a map unit has at least one
component where this value is not null.

For an attribute of a soil horizon, a depth qualification must be specified. In most
cases it is probably most appropriate to specify a fixed depth range, either in
centimeters or inches. The Bottom Depth must be greater than the Top Depth,
and the Top Depth can be greater than zero. The choice of "inches" or
"centimeters" only applies to the depth of soil to be evaluated. It has no influence
on the units of measure the data are presented in.
When "Surface Layer" is specified as the depth qualifier, only the surface layer or
horizon is considered when deriving a value for a component, but keep in mind
that the thickness of the surface layer varies from component to component.
When "All Layers" is specified as the depth qualifier, all layers recorded for a
component are considered when deriving the value for that component.
Whenever more than one layer or horizon is considered when deriving a value
for a component, and the attribute being aggregated is a numeric attribute, a
weighted average value is returned, where the weighting factor is the layer or
horizon thickness.

Description
Clay as a soil separate consists of mineral soil particles that are less than 0.002
millimeter in diameter. The estimated clay content of each soil layer is given as a
percentage, by weight, of the soil material that is less than 2 millimeters in
diameter. The amount and kind of clay affect the fertility and physical condition of
the soil and the ability of the soil to adsorb cations and to retain moisture. They
influence shrink-swell potential, saturated hydraulic conductivity (Ksat), plasticity,
the ease of soil dispersion, and other soil properties. The amount and kind of clay
in a soil also affect tillage and earth-moving operations.
Most of the material is in one of three groups of clay minerals or a mixture of
these clay minerals. The groups are kaolinite, smectite, and hydrous mica, the
best known member of which is illite.
For each soil layer, this attribute is actually recorded as three separate values in
the database. A low value and a high value indicate the range of this attribute for
the soil component. A "representative" value indicates the expected value of this
attribute for the component. For this soil property, only the representative value is

Description
A "restrictive layer" is a nearly continuous layer that has one or more physical,
chemical, or thermal properties that significantly impede the movement of water
and air through the soil or that restrict roots or otherwise provide an unfavorable
root environment. Examples are bedrock, cemented layers, dense layers, and
frozen layers.
This theme presents the depth to any type of restrictive layer that is described for
each map unit. If more than one type of restrictive layer is described for an
individual soil type, the depth to the shallowest one is presented. If no restrictive
layer is described in a map unit, it is represented by the "> 200" depth class.
This attribute is actually recorded as three separate values in the database. A
low value and a high value indicate the range of this attribute for the soil
component. A "representative" value indicates the expected value of this attribute
for the component. For this soil property, only the representative value is used.

Aggregation is the process by which a set of component attribute values is
reduced to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is
either some type of soil or some nonsoil entity, e.g., rock outcrop. For the
attribute being aggregated, the first step of the aggregation process is to derive
one attribute value for each of a map unit's components. From this set of
component attributes, the next step of the aggregation process derives a single
value that represents the map unit as a whole. Once a single value for each map
unit is derived, a thematic map for soil map units can be rendered. Aggregation
must be done because, on any soil map, map units are delineated but
components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding
component typically makes up approximately 60% of the map unit. Percent
composition is a critical factor in some, but not all, aggregation methods.
The aggregation method "Dominant Component" returns the attribute value
associated with the component with the highest percent composition in the map
unit. If more than one component shares the highest percent composition, the
corresponding "tie-break" rule determines which value should be returned. The
"tie-break" rule indicates whether the lower or higher attribute value should be
returned in the case of a percent composition tie. The result returned by this
aggregation method may or may not represent the dominant condition throughout
the map unit.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. If no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Tie-break Rule: Lower
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.
Interpret Nulls as Zero: No
This option indicates if a null value for a component should be converted to zero
before aggregation occurs. This will be done only if a map unit has at least one
component where this value is not null.

APPLICATION FOR MINOR SUBDIVISION
RESPONSE TO STANDARDS IN SECTION 7
DIVISION 1. GENERAL APPROVAL STANDARDS.
7-101. Zone District Use Regulations
The Property is in the County’s Rural zone district. The Rural district permits rural residential
areas, agricultural resource lands, and agricultural production areas.
7-102. Comprehensive Plan and Intergovernmental Agreements
The proposed land use is generally and specifically in conformance with the Garfield County
Comprehensive Plan. The property is within the Comprehensive Plan’s future land use designation
of Residential Low, which suggests 1 dwelling unit per 10 acres. All lots are at least 10 acres.
7-103. Compatibility
The nature, scale, and intensity of the proposed use is compatible with adjacent land uses,
which include rural residential uses.
7-104. Source of Water
The Property has physical and legal water supply. See Sections 8.A. and 8.B.
7-105. Central Water Distribution and Wastewater Systems
The water distribution and wastewater systems are adequate to serve the proposed use and
density. See Section 10.
7-106. Public Utilities
Adequate public utilities are available to serve the land use. Included in this Application is a
can and will serve letter from Holy Cross.
7-107. Access and Roadways
The properties have legal access to County Road 107. The Applicant will record an easement
at the time of recordation of the final plat which provides all lots reciprocal access across the roadways
within the subdivision, as well as for the Broadhurst lot north of the subdivision, which is already the
beneficiary of an easement through the KRB property.
The existing roadway is an asphalt surface between 11-20 feet wide throughout the project
area. According to the Basic Traffic Analysis, the internal roads already function as a “Semi-Primitive
Roadway” under the County’s road classification set forth in Table 7-107 of the GCULUR. When
considering the traffic generated from the 2 new lots (even assuming 3 new ADUs), the cumulative
traffic still operates within the same “Semi-Primitive Roadway” category. The internal roadway right
of way will be 40 feet wide, though short portions of the easement connecting back to the County
Road are slightly narrower. To the extent this causes the need for a waiver, please consider this a
request for a waiver from the roadway standards. As support, see Section 14.A.i., which is a letter
from Bill Gavette, Deputy Chief of the Carbondale and Rural Fire Department opining that the
roadways are capable of adequately servicing the 2 proposed lots and for emergency access concerns.
Section 14.A. is a Basic Traffic Analysis conducted by SGM Engineering concluding the proposed
development access will operate acceptably and safely considering the increased traffic from the
proposed two additional lots (See Paragraph 4.1).
With regard to the Waver Criteria in the GCULUR (4-118), the existing physical roadway
network achieves the intent of the roadway standards to the same or better degree than the subject
standard. This is shown by the engineering conclusion and letter from Bill Gavette, which both find
the physical access to the site is safe, operational, and meet the intent of the roadway standards in the
code. Additionally, the waiver creates no greater impacts on adjacent properties than would occur
through compliance with the specific requirements of the Code. Indeed, it imposes less impacts
because the standard would likely require greater legal and physical road width, when clearly such
additional taking of private property is unnecessary for an additional 2 rural lots. Note also that Semi-
Primitive Roadways are only required to maintain a gravel surface, whereas this road is new asphalt,
thereby better achieving the intent of the roadway standards.
7-108. Use of Land Subject to Natural Hazards
It is Applicant’s understanding that the property has moderate slope related hazards and
moderate soils-related hazards according to the Garfield County Geologic Hazard GIS. To mitigate
these potential hazards, Applicant will include notes on the plat that all foundations be engineered.
7-109. Fire Protection
The proposed land use meets the standards set forth in 7-109. Applicant has consulted with
the fire district, which supports the project. See Section 14.A.i. which is a letter of support from the
Carbondale and Rural Fire Department.
DIVISION 2. GENERAL RESOURCE PROTECTION STANDARDS.
7-201 Agricultural Lands
The proposed use does not impact agricultural operations or otherwise affect or limit the
viability of existing agricultural operations. The application otherwise complies with the standards in
7-201. Indeed, this application ensures future viability of agriculture on the parcels.
7-202 Wildlife Habitat Areas
The proposed land use will not impact wildlife habitat areas. Please see Section 14.D. which
is a letter from SGM dated September 15, 2020.
7-203 Protection of Waterbodies
There are no waterbodies on the property.
7-204. Drainage and Erosion
The proposed land use has adequate drainage in place and otherwise complies with 7-204.
7-205. Environment Quality
The proposed use will not cause air quality to be reduced below acceptable levels, and will not
adversely impact water quality.
7-206 Wildfire Hazards
It is Applicant’s understanding that the site is not in an elevated Wildfire hazard zone.
7-207. Natural and Geologic Hazards
It is Applicant’s understanding that the property has moderate slope related hazards and
moderate soils-related hazards.
7-208. Reclamation
N/A.
DIVISION 3. SITE PLANNING AND DEVELOPMENT STANDARDS.
7-301. Compatible Design
The site plan is compatible with the existing character of adjacent land uses and will comply
with Section 7-301.
7-302. Off-Street Parking and Loading Standards
The proposed use will comply with Section 7-302.
7-303. Landscaping Standards
The Applicant will be in compliance with 7-303(C), but to the extent this section applies,
Applicant requests a waiver.
7-304. Lighting Standards
The project complies with the lighting standards of Section 7-304.
7-305. Snow Storage Standards
The Applicant is exempt from this Section.
7-306. Trail and Walkway Standards
Section 7-306 does not apply to the proposed use, but to the extent this section applies,
Applicant requests a waiver.
DIVISION 4. SUBDIVISION STANDARDS AND DESIGN SPECIFICATIONS.
7.401. General Subdivision Standards
The project complies with Section 7.401.
7.402. Subdivision Lots
The project complies with Section 7.402.
7.403. Survey Monuments
The project complies with Section 7.403.
7.404. School Land Dedication
Applicant is requesting to pay a fee-in-lieu as permitted by Section 7.404. The calculation of
this fee is based on the unimproved fair market value of the land, with a minimum fee of $500. See
Section 12.A. which is a Broker’s Professional Opinion of the unimproved fair market value of the
land prior to final plat, which is $1,023,000. The formula is the (unimproved per acre FMV of land)
X (land dedication standard) X (Number of Units) = Payment. Here, the formula is ($23,250) X [(.02)
x (0.49)] X (3 dwelling units) = $683.55.
7.405. Road Impact Fees
Road Impact Fees will be paid at the time of building permit, per Section 7-405(A)(1).

Re: unimproved fair market value KRB LLC (Parcel 239321400312)
Dear Chad,
You asked me for an “unimproved fair market value” for the KRB LLC 44 acres located off of County Road 107 in
Carbondale.
For this analysis the 44-acres is considered unimproved. I mapped the acres and came up with 35.5 acres of
dryland with Juniper/Pinon hillside and 8.5 acres of irrigated pasture/hay ground. (Please see the attached map)
Using data from the Aspen/Glenwood Springs MLS and the Garfield County Assessor records, along with
consideration for the location, views and proximity to Carbondale, I came up with the following value:
$15,000/acre for the 35.5 acres of tree covered ground = $560,000
$54,500/acre for the 8.5 acres of irrigated pasture/hay = $463,000
The total value of the KRB LLC 44-acre parcel inclusive of water rights, mineral rights and no deed restriction is
$1,023,000.00. I have included a Statistical CMA for your review.
Please let me know if you have any questions or need further information.

CGS LAND USE REVIEWS
Geological studies are required by Colorado counties for all subdivisions of unincorpo-
rated land into parcels of less than 35 acres, under State statute C.R.S. 30-28-136 (1) (i)
(Senate Bill 35, 1972). Some Colorado municipalities require geological studies for sub-
division of incorporated land. In addition, local governments are empowered to regu-
late development activities in hazardous or mineral-resource areas under C.R.S. 24-65.1-
101 et seq. (House Bill 1041, 1974) and C.R.S. 34-1-301 et seq. (House Bill 1529, 1973),
respectively.
Local-government agencies submit proposed subdivision applications and supporting
technical reports to the Colorado Geological Survey ”...for evaluation of those geologic
factors which would have significant impact on the proposed use of the land,“ in accor-
dance with State statutes. The CGS reviews the submitted documents and serves as a
technical advisor to local-government planning agencies during the planning process.
Since 1984, the CGS has been required by law to recover the full direct cost of perform-
ing such reviews.
The adequate knowledge of a site’s geology is essential for any development project. It
is needed at the start of the project in order to plan, design, and construct a safe devel-
opment. Proper planning for geological conditions can help developers and future
owners/users reduce unnecessary maintenance and/or repair costs.

Frequently Asked Questions and Answers
Regarding the CGS Land Use Review Process
1 Why am I required to have a CGS review when I already hired
and paid for my own consultant?
In 1972, Senate Bill 35 was passed stating that any person or
entity subdividing a property into parcels of 35 acres or less on
unincorporated land must submit geologic or geotechnical
reports to the County as part of the preliminary plat application
process. Municipalities or public agencies may request that CGS
review a site, although these reviews are not governed by the
statute.
7 The subdivision down the road was approved, why wasn’t mine?
There could be several reasons: geologic conditions can change
over short distances; subdivisions made prior to 1972 were not
required to undergo a CGS review and may have not been
evaluated for geologic suitability at all; the area down the road
may be incorporated as part of a municipality, which exempts it
from the CGS review process. Another consideration is that
geologic reviews are continually evolving and site conditions that
have been judged acceptable in the past may no longer be
considered as such, based on the current understanding of the
geologic processes and adverse impacts associated with them. 2 Why is a CGS review necessary when I already hired my own
geologist?
8 Why are CGS reviews required even on low-density properties? The CGS review is an independent third-party review that is done
for the County, similar to the service a building inspector provides
for construction review. The purpose of the CGS review is to
ensure that all geologic concerns have been adequately identified
and addressed in the geologic reports and that the proposed
development is feasible.
Senate Bill 35 pertains to subdivisions of less than 35 acres.
Geologic hazards can occur on large-scales or small-scales;
relying on low-density subdivision can not mitigate all geologic
hazards. For instance, entire hillsides might be prone to rockfall
or landslide hazards. Large tracts of land may be subject to
groundwater problems.
3 Why does CGS charge for land use reviews? Doesn’t taxpayer
money pay for this service? 9 Why can’t I just use the soil conservation maps for a geologic
report? CGS land use reviews are not subsidized through the general
fund, although some other review agencies are supported by
taxpayer money. In 1984 the state legislature decided that CGS
reviews should be paid for with fees paid by the applicant of the
proposed development so that taxpayers are not viewed as
subsidizing development.
The USDA soil conservation maps are a good start for geologic
investigations, but do not contain sufficient detail on the possible
geologic problems that may occur at any site.
10 Aren’t some of your review comments beyond the scope of geologic
hazards on my site?
4 Did the CGS geologist make a field visit to the site?
CGS geologists conduct site visits as necessary. I
Technically other agencies have regulatory authority regarding
issues such as flood plains, groundwater availability and wildfire,
but these issues are also important factors in the overall geologic
context of the site and may affect geologic hazards on the site. The
mention of a condition in the CGS review letter is not intended to
influence the statutory authority of any other agency, but rather to
ensure that all parties are aware of a potentially problematic
geologic condition. For instance, mention of a situation involving a
major drainage is a flag that the U.S. Army Corps of Engineers or
the Colorado Water Conservation Board should be reviewing
development plans.
f the review is a
re-submittal for a site that has been visited previously, a second
site visit may not be necessary. If significant changes have
occurred since the initial review, the site may be visited again.
5 Why is the CGS review letter so short and simple? What is my fee
paying for?
The CGS letter is a review of the geologic material submitted and
reflects the level of detail contained in those documents. CGS does
not offer designs, but rather ensures that the work that has been
done is meaningful and adequate for the site conditions and
proposed development. A site review that adequately addresses all
the geologic conditions present at the site may be a short
confirmation letter. If more work needs to be done or if difficult
site conditions are present, the letter may be longer.
11 When I bought this property, no one told me about any geologic
hazards on the site; can I go back to the previous owners
somehow?
CGS can not give legal advice. If the seller was aware of adverse
conditions with respect to the proposed use, this should have
been disclosed. A legal opinion should be sought. 6 What type of information do I need to submit to CGS for a land
use review?
The more geologic information that is submitted to CGS, the
easier it is for CGS to evaluate the property. The required
documents may vary based on county requirements and the
potential problems that may impact the proposed development.
A topographic map is essential. Also, information regarding
slope, surficial materials, subsurface materials and bedrock,
presence of groundwater and depth, and specific geologic
hazards should be included, where applicable. Grading plans,
drainage plans, and geotechnical testing results are also very
helpful for the review. The presence of geologic hazards should
be evaluated with respect to the development plan. Also, the
effect of development on geologic conditions should be
discussed. The evaluation should include alternatives such as
avoidance and mitigation techniques.
12 Can I get a waiver from having the CGS do a review?
The discretion to grant waivers is vested by law with the counties.
Once an application for review is submitted to CGS, we are under
a statutory responsibility to respond.
13 I am willing to accept the risk associated with my property —
why is it anyone’s business what I do with my own land?
The presumption associated with a subdivision is that portions
of the property will be sold to others. This then assigns any risk
to future buyers, and the county is required to protect their
interests. Senate Bill 35 addresses a wide variety of land use
issues as well as geologic suitability in an attempt to provide
information so that the overall appropriateness of the
subdivision proposal can be evaluated.

RE: 1434 County Road 107, Proposed Subdivision, Road Access
Dear Rick,
Thanks for the opportunity to meet with you last week and review the road access for your
property off County Road 107. It is my understanding that you intend to subdivide your existing
parcel in order to create two new ten acre parcels.
The existing paved single lane driveway creates a loop that connects back to County Road 107 .
The total length of the loop is approximately 1.5 miles long and includes pullouts along the way
that allow opposing vehicles to pass . The existing looped driveway is adequate for our
emergency apparatus and is capable of adequately servicing the two new proposed lots .
Please contact me is you have any questions or if I may be of any assistance.

and well locations are shown on Figure 1, which can be found in the Appendix.
4.2 Local Public Health Agency Records.
Existing Sewage Disposal Systems: According to County Public Records there have been
two existing sewage disposal systems permitted for the existing property. One is an ISDS
approved for a 3 bedroom residence dated 7/09/1990. It is believed this system provides
sewage treatment for the existing residence at 1434 County Road 107, Carbondale,
Colorado. The other system is an approved ISDS associated with a prefabricated steel
building having a ½ bath and loft, dated 4/25/2016. Both permits have the address of 1434
County Road 107, Carbondale, Colorado.
4.3 Public Site Information.
Topography and Soil Data: Grade percentages and soil data for the subject property were
downloaded from the National Resource Conservation Services (NRCS) Soil Web Site.
The data indicates there are two major soil units within the proposed minor subdivision, soil
unit 35 and soil unit 106.
Soil unit 35 consists of Empedrado loam, which has grades between 6 to 12 percent. In
addition, NRCS rates this soils unit as having 33.6% silts, 35.4% sands and 31% clays with
a depth to the most restrictive layer as being greater than 6.5 feet. Proposed minor
subdivision Lot 1 contains approximately 20.110 acres, Lot 2 approximately 4.224 acres
and NRCS soil unit 35 is not found in Lot 3.
Soil unit 106 consist of Tridell-Brownsto stony sandy loams, which has grades between 12
to 50 percent. In addition, NRCS rates this soil unit as having 9.0% silts, 83.5% sands and
7.5% clays with a depth to the most restrictive layer being greater than 6.5 feet. In
proposed Lot 1 of the minor subdivision there is approximately 4.135 acres of NRCS soil
unit 106, 5.776 acres in proposed Lot 2 and 10.000 acres in proposed Lot 3.
OWTS can be installed on slopes up to 30 percent (3.3H:1V) without having to be designed
by a professional engineer registered and licensed to practice in the State of Colorado. Per
the NRCS soil unit data, there may be some areas within proposed minor subdivision Lots
1, 2 and 3 that may be in excess of the 30 percent criterion and would require engineered
design.
4.4 Location of Physical Features Requiring Setbacks per Table 7-1 of the County’s OWTS
Regulations.
The location of known existing features that require setbacks per Table 7-1 of the County’s
OWTS Regulations are shown on Figure 1. It is not known at this time where proposed
features will be located that will require setbacks in accordance with Table 7-1, but there is
ample acreage available for each proposed minor subdivision lot to meet future setback
requirements due to installation of future features.

Regulations. Maximum wastewater generation design flow =
2,000 gpd, unless criteria in 2 and 3 under Authority can be met
and demonstrated.
Determination of the required square footage for the STA is dependent on the residential
design flow divided by the infiltrative soils LTAR. The LTAR for use in the preliminary STA
size estimate is found by using the United States Department of Agriculture’s (USDA)
textural triangle in conjunction with percentages of silt, sand and clay found in the NRCS
soils data. On the triangle, percentages for silt, sand and clay are plotted. The point where
the three cross is the USDA soil texture, which relates to the soil type and determines the
LTAR.
For NRCS soil unit 35, the soil texture is a clay loam, which could be a soil type 3 or 3A. A
soil type 3 has a LTAR of 0.35 gpd/ft2 and soil type 3A has a LTAR of 0.30 gpd/ft2. To break
the tie for actual design, more information is required, which is collected during the detailed
soil investigation. However, for the preliminary STA size estimate, the more conservative
LTAR associated with soil type 3A is used, 0.30 gpd/ft2. It should be mentioned that a soil
type 3A requires design by a professional engineer registered and licensed to practice in
the State of Colorado.
For NRCS soil unit 106, the soil texture is a loamy clay, which has a soil type classification
of 5. Soil type 5 has a LTAR OF 0.10 gpd/ft2 and also requires design by a professional
engineer registered and licensed to practice in the State of Colorado.
Using the LTAR’s determined for NRCS soil units 35 and 106, the following table reflects
the estimated STA size for residences up to a count of 6 bedrooms.

The estimated STA size is without adjustment factors being applied. Garfield County’s
OWTS Regulations allow for adjustment factors to be applied based on the method of effluent
application to the STA and the distribution media used in the STA.
The method of effluent application to the STA can be by gravity, dosed (siphon or pumped)
and pressure dosed. Size adjustment factors for method of effluent application are shown in
the following table.

The maximum required square footage required to install a STA for the proposed subdivision
lots would be determined using gravity for the method of effluent application to a soil
absorption bed with a category 1 distribution media. The following table shows the maximum
required square footage to install a STA in NRCS soil unit 35, based on the number of
residential bedrooms and using the most stringent adjustment factors.

The actual site area required to install the STA will be the direct result of the OWTS design,
which is based on:
· The actual number of bedrooms for the residential structure.
· The type of absorption area used; trench or bed.
· The method of effluent application to the absorption area; gravity, dosed (siphon or
pumped) or pressure dosed.
· The type of distribution media used in the absorption area; category 1, category 2 or
category 3.
· Or utilization of a higher level treatment system.
However, to keep the perspective in line with the scope of this report, which is to determine
the feasibility to install a STA, the maximum required site area will be determined using the
following design criteria:
· The absorption area is a bed with a maximum width of 12 feet and at least 6 feet
between bed sidewalls.
· The absorption media is category 1.
· Effluent application is by gravity.
· Maximum distribution lateral length is 100 feet.
· Distribution box is located at the center of the lateral.

The above tables were developed using the most stringent adjustment factors for sizing a
STA and indicates that it is feasible to install an OWTS in NRCS soil unit 35 for up to at least
a 6 bedroom residence. The tables indicate that for NRCS soil unit 106 it is bordering
whether it is feasible or not feasible for construction of a 2 bedroom residence. Anything
larger does not appear to be feasible for installation of an OWTS when using the most
stringent adjustment factors.
However, using less stringent adjustment factors in NRCS soil unit 106, i.e. a trench with an
application method of pressure dosing, in addition to chambers results in a STA having the
following sizes.

The above two tables indicate that it is feasible to install a STA in NRCS soil unit 106 by
changing the effluent application method and distribution media. In addition, the total

required site area can be further reduced by treating wastewater to at least treatment level 2,
TL2.
Lastly, it should be noted that all of the above tables represent STA sizes based on data
from the NRCS “Web Soil Survey” site, which is useful in determining the feasibility of
installing an OWTS prior to actually collecting on-site field data. However, it has been
SGM’s experience that actual required site areas for the installation of a STA is reduced
when using data developed from the detailed site soil investigation, which is required for
actual design of an OWTS.

Description
Silt as a soil separate consists of mineral soil particles that are 0.002 to 0.05
millimeter in diameter. In the database, the estimated silt content of each soil
layer is given as a percentage, by weight, of the soil material that is less than 2
millimeters in diameter.
The content of sand, silt, and clay affects the physical behavior of a soil. Particle
size is important for engineering and agronomic interpretations, for determination
of soil hydrologic qualities, and for soil classification
For each soil layer, this attribute is actually recorded as three separate values in
the database. A low value and a high value indicate the range of this attribute for
the soil component. A "representative" value indicates the expected value of this
attribute for the component. For this soil property, only the representative value is
used.

Aggregation is the process by which a set of component attribute values is
reduced to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is
either some type of soil or some nonsoil entity, e.g., rock outcrop. For the
attribute being aggregated, the first step of the aggregation process is to derive
one attribute value for each of a map unit's components. From this set of
component attributes, the next step of the aggregation process derives a single
value that represents the map unit as a whole. Once a single value for each map
unit is derived, a thematic map for soil map units can be rendered. Aggregation
must be done because, on any soil map, map units are delineated but
components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding
component typically makes up approximately 60% of the map unit. Percent
composition is a critical factor in some, but not all, aggregation methods.
The aggregation method "Dominant Component" returns the attribute value
associated with the component with the highest percent composition in the map
unit. If more than one component shares the highest percent composition, the
corresponding "tie-break" rule determines which value should be returned. The
"tie-break" rule indicates whether the lower or higher attribute value should be
returned in the case of a percent composition tie. The result returned by this
aggregation method may or may not represent the dominant condition throughout
the map unit.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. If no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Tie-break Rule: Higher
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.
Interpret Nulls as Zero: No
This option indicates if a null value for a component should be converted to zero
before aggregation occurs. This will be done only if a map unit has at least one
component where this value is not null.

For an attribute of a soil horizon, a depth qualification must be specified. In most
cases it is probably most appropriate to specify a fixed depth range, either in
centimeters or inches. The Bottom Depth must be greater than the Top Depth,
and the Top Depth can be greater than zero. The choice of "inches" or
"centimeters" only applies to the depth of soil to be evaluated. It has no influence
on the units of measure the data are presented in.
When "Surface Layer" is specified as the depth qualifier, only the surface layer or
horizon is considered when deriving a value for a component, but keep in mind
that the thickness of the surface layer varies from component to component.
When "All Layers" is specified as the depth qualifier, all layers recorded for a
component are considered when deriving the value for that component.
Whenever more than one layer or horizon is considered when deriving a value
for a component, and the attribute being aggregated is a numeric attribute, a
weighted average value is returned, where the weighting factor is the layer or
horizon thickness.

Description
Sand as a soil separate consists of mineral soil particles that are 0.05 millimeter
to 2 millimeters in diameter. In the database, the estimated sand content of each
soil layer is given as a percentage, by weight, of the soil material that is less than
2 millimeters in diameter. The content of sand, silt, and clay affects the physical
behavior of a soil. Particle size is important for engineering and agronomic
interpretations, for determination of soil hydrologic qualities, and for soil
classification.
For each soil layer, this attribute is actually recorded as three separate values in
the database. A low value and a high value indicate the range of this attribute for
the soil component. A "representative" value indicates the expected value of this
attribute for the component. For this soil property, only the representative value is
used.

Aggregation is the process by which a set of component attribute values is
reduced to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is
either some type of soil or some nonsoil entity, e.g., rock outcrop. For the
attribute being aggregated, the first step of the aggregation process is to derive
one attribute value for each of a map unit's components. From this set of
component attributes, the next step of the aggregation process derives a single
value that represents the map unit as a whole. Once a single value for each map
unit is derived, a thematic map for soil map units can be rendered. Aggregation
must be done because, on any soil map, map units are delineated but
components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding
component typically makes up approximately 60% of the map unit. Percent
composition is a critical factor in some, but not all, aggregation methods.
The aggregation method "Dominant Component" returns the attribute value
associated with the component with the highest percent composition in the map
unit. If more than one component shares the highest percent composition, the
corresponding "tie-break" rule determines which value should be returned. The
"tie-break" rule indicates whether the lower or higher attribute value should be
returned in the case of a percent composition tie. The result returned by this
aggregation method may or may not represent the dominant condition throughout
the map unit.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. If no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Tie-break Rule: Higher
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.
Interpret Nulls as Zero: No
This option indicates if a null value for a component should be converted to zero
before aggregation occurs. This will be done only if a map unit has at least one
component where this value is not null.

For an attribute of a soil horizon, a depth qualification must be specified. In most
cases it is probably most appropriate to specify a fixed depth range, either in
centimeters or inches. The Bottom Depth must be greater than the Top Depth,
and the Top Depth can be greater than zero. The choice of "inches" or
"centimeters" only applies to the depth of soil to be evaluated. It has no influence
on the units of measure the data are presented in.
When "Surface Layer" is specified as the depth qualifier, only the surface layer or
horizon is considered when deriving a value for a component, but keep in mind
that the thickness of the surface layer varies from component to component.
When "All Layers" is specified as the depth qualifier, all layers recorded for a
component are considered when deriving the value for that component.
Whenever more than one layer or horizon is considered when deriving a value
for a component, and the attribute being aggregated is a numeric attribute, a
weighted average value is returned, where the weighting factor is the layer or
horizon thickness.

Description
Clay as a soil separate consists of mineral soil particles that are less than 0.002
millimeter in diameter. The estimated clay content of each soil layer is given as a
percentage, by weight, of the soil material that is less than 2 millimeters in
diameter. The amount and kind of clay affect the fertility and physical condition of
the soil and the ability of the soil to adsorb cations and to retain moisture. They
influence shrink-swell potential, saturated hydraulic conductivity (Ksat), plasticity,
the ease of soil dispersion, and other soil properties. The amount and kind of clay
in a soil also affect tillage and earth-moving operations.
Most of the material is in one of three groups of clay minerals or a mixture of
these clay minerals. The groups are kaolinite, smectite, and hydrous mica, the
best known member of which is illite.
For each soil layer, this attribute is actually recorded as three separate values in
the database. A low value and a high value indicate the range of this attribute for
the soil component. A "representative" value indicates the expected value of this
attribute for the component. For this soil property, only the representative value is
used.

Description
A "restrictive layer" is a nearly continuous layer that has one or more physical,
chemical, or thermal properties that significantly impede the movement of water
and air through the soil or that restrict roots or otherwise provide an unfavorable
root environment. Examples are bedrock, cemented layers, dense layers, and
frozen layers.
This theme presents the depth to any type of restrictive layer that is described for
each map unit. If more than one type of restrictive layer is described for an
individual soil type, the depth to the shallowest one is presented. If no restrictive
layer is described in a map unit, it is represented by the "> 200" depth class.
This attribute is actually recorded as three separate values in the database. A
low value and a high value indicate the range of this attribute for the soil
component. A "representative" value indicates the expected value of this attribute
for the component. For this soil property, only the representative value is used.

Aggregation is the process by which a set of component attribute values is
reduced to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is
either some type of soil or some nonsoil entity, e.g., rock outcrop. For the
attribute being aggregated, the first step of the aggregation process is to derive
one attribute value for each of a map unit's components. From this set of
component attributes, the next step of the aggregation process derives a single
value that represents the map unit as a whole. Once a single value for each map
unit is derived, a thematic map for soil map units can be rendered. Aggregation
must be done because, on any soil map, map units are delineated but
components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding
component typically makes up approximately 60% of the map unit. Percent
composition is a critical factor in some, but not all, aggregation methods.
The aggregation method "Dominant Component" returns the attribute value
associated with the component with the highest percent composition in the map
unit. If more than one component shares the highest percent composition, the
corresponding "tie-break" rule determines which value should be returned. The
"tie-break" rule indicates whether the lower or higher attribute value should be
returned in the case of a percent composition tie. The result returned by this
aggregation method may or may not represent the dominant condition throughout
the map unit.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. If no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Tie-break Rule: Lower
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.
Interpret Nulls as Zero: No
This option indicates if a null value for a component should be converted to zero
before aggregation occurs. This will be done only if a map unit has at least one
component where this value is not null.

RE: Broadhurst Parcels Preliminary Environmental Review
Dear Chad,
At your request, a preliminary review of the Broadhurst Parcels was conducted regarding compliance with the
Garfield County Land Use Code. Specifically, we reviewed these parcels considering a minor subdivision action.
The majority of the parcel is dominated by agricultural pastures, with remnant stands of sagebrush around the
perimeter. There are some areas dominated by pinyon pine (Pinus edulis) and Utah juniper (Sabina osteosperma)
woodlands. These habitat types are relatively common in the greater area. There are no obvious areas of wetlands
or other hydric features.
Based on CPW wildlife activity maps, the parcel lies within elk Severe Winter Range, and Winter Range, and lies
within mule deer Severe Winter Range, Winter Concentration Area, and Winter Range (see attached maps). The
parcel also lies within a black bear Fall Concentration Area.
Based on this preliminary review, I do not foresee significant issues that would preclude development of the parcel,
but some recommendations regarding development locations to cluster or avoid some areas may be requested by
CPW. CPW may also request habitat mitigation fees, and this would be at the discretion of the owner whether they
would entertain some level of providing either funds or possibly habitat improvement actions on the property. Other
standard wildlife “best management practices”, such as wildlife friendly fencing, bear proof trash receptacles, etc.,
would also be recommended.
Best regards,
Eric Petterson

REPRESENTATIVE: Chad Lee
PRACTICAL LOCATION: 1434 County Road 107, Carbondale, CO 81623
TYPE OF APPLICATION: Minor Subdivision
ZONING: Rural
SIZE: 44.25 Acres
I. GENERAL PROJECT DESCRIPTION
The applicant is proposing a Minor Subdivision to split the 44.25-acre property into three lots
in the Rural Zone District The applicant should note that the minimum lot size in the Rural
zone district is 2-acres, while the Comprehensive Plan suggested density is greater than 10
acres. The applicant is still determining the exact proposed acreages. The property is
currently improved with an existing single-family residence, served by an existing well and
OWTS (on-site wastewater treatment system). The applicant is proposing to serve the new
lots with a shared well with a Basalt Water Conservancy District Contract.
The Subdivision requires a demonstration of legal and adequate water for all of the proposed
parcels, Staff encourages the applicant to discuss the subdivision with the Division of Water
Resources (DWR) (Contact Dwight Whitehead at the DWR at 970-945-5665 ext. 5011) prior
to submitting an application for subdivision with the County. In addition, a water quality test
and pump test will need to be conducted prior to application submittal in accordance with
Section 4-203(M)(1)(b)(5). However, the applicant may request that water quality and
quantity tests be conducted as conditions of approval.
All proposed parcels will be accessed from a private road off of County Road 107. All private
driveways and access roads need to conform to the dimensional requirements in Section 7-
107 of the LUDC. Additionally, the private road appears to be a significant distance. The
application should present information indicating that the access is adequate for emerg ency
service ingress and egress.
A review of the hazard mapping for the area indicates that the parcel has moderate slope-
related hazards and moderate soils-related hazards. These items should be addressed as
part of the application.

Waiver for Road Standards
KRB Investments, LLC Minor Subdivision
Dear Vince,
This letter responds to item 8 of your February 8, 2021 completeness review letter to Chad Lee
which stated:
Please consider this a formal request for a waiver from the Roadway Design Standards listed in
Table 7-107. The remainder of this letter will address the specific standards and demonstrate
compliance with Policy 01-14 with responses that follow the order and requirements of that
document in conformance with the definitions and intent of the LUDC.
Policy 01-14 Waivers for Roads and Demonstration of Compliance
The three lots of the proposed minor subdivision will be served by an existing “private road” and
an additional “emergency access” road that form a loop back to CR 107. These roads do not
serve the general public. Based on available Google Earth aerial imagery, the roads existed in
1993 and therefore pre-date the LUDC Table 7– 107 standards. Based on my personal
experience in driving and evaluating the northerly subdivision “private road” and southerly
emergency access loop road last year, these roads do provide for “adequate and safe access”
for the residential uses proposed. Refer to the “Existing Road Photos” that follow this letter.
Besides accommodating the limited residential traffic, the existing roads provide suitable access
for emergency vehicles. The existing road access is acceptable to the Carbondale and Rural
Fire Protection District. Deputy Chief Bill Gavette has provided a letter stating the following:
www.sgm-inc.com
GLENWOOD SPRINGS 118 West Sixth St, Suite 200 | Glenwood Springs, CO 81601 | 970.945.1004
LUDC 4-118 C. Review Criteria are as follows: A waiver may be approved if the Applicant
demonstrates that the following criteria have been met by the proposed alternative:
1. It achieves the intent of the subject standard to the same or better degree
than the subject standard; and
2. It imposes no greater impacts on adjacent properties than would occur
through compliance with the specific requirements of this Code.
Regarding item 1, the intent is “adequate and safe access” and the existing road provides that
for the existing residences just as it will for the two news lots. Specific standards discussed
below.
For item 2, the existing road imposes no impacts on adjacent properties while re-constructing
the road for sake of compliance with a standard would impose significant impacts during
construction.
Statement of Adequacy
The existing road will be adequate for residential and emergency traffic associated with the
minor subdivision.
o Geometry of the road
As described in the Basic Traffic Analysis, the “Semi-Primitive” classification applies to
the existing and proposed use levels. Refer the specific standards in that column below
and the attached plan and profile exhibit.

o Safety/Structural Issues – The existing asphalt road is in superb structural condition
and the narrow road width may be the only perceived safety issue. Given that this is a
private road and users will obtain familiarity upon first trip this is not really a safety
concern. Also, emergency services has deemed the road sufficient.
o Maintenance – The road is currently maintained by the residents that live there without
a formal agreement. Upon approval of the minor subdivision, future lot owners will be
required to enter into a proposed road maintenance agreement (attached).
o Travel Demand – Calculated ADT is 55 trips existing and 95 trips proposed. Refer to the
project traffic report. Besides these the ultimate residential traffic, the road will see
temporary construction traffic as the new homes are constructed.
Other Evidence of Compliance Section 7-107
A. Access to Public Right-of-Way - Legal access is provided via County Road 107.
B. Safe Access – This existing asphalt access road is safe and typical of or better than
roads serving many Garfield County residential properties. The proposed minor
subdivision triggers no warrants for improvements to State, Federal or County roads.
Refer to the Basic Traffic Analysis.

GLENWOOD SPRINGS 118 West Sixth St, Suite 200 | Glenwood Springs, CO 81601 | 970.945.1004
C. Adequate Capacity – The proposed minor subdivision produces a minimal increase in
traffic and will not cause traffic congestion on the existing access road or on CR 107 &
SH 82. Refer to the Basic Traffic Analysis.
D. Road Dedications – The Plat identifies the 40’ Private Road ROW to be dedicated by
separate document.
E. Impacts Mitigated – The proposed residences will be required to pay any applicable
impact fees to mitigate impacts to County roads.
If additional clarifications are needed, please call my direct line at (970) 384-9008.

(“Plat” or “Broadhurst Minor Subdivision”).
B. Whereas, there currently exists a paved single lane driveway which provides
vehicular access to Lots 1, 2, and 3 of the Broadhurst Minor Subdivision and which connects to
County Road 107.
C. Whereas, the Declarant intends to memorialize that future owner of Lots 1, 2, and
3 of the Broadhurst Minor Subdivision are entitled to shared access over the existing roadway to
access their respective parcels, which roadway is more particularly described on the Plat of the
Broadhurst Minor Subdivision and incorporated herein by this reference (the “Shared Roadway”
or “Access Easement” defined below).
D. Declarant desires to make this Declaration to establish a perpetual access easement
and to provide for the allocation of the costs of maintenance and future capital improvement of the
Shared Roadway.
Declaration
NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency is
hereby acknowledged, the parties hereto agree as follows:
1. Incorporation of Recitals. The foregoing Recitals are true and correct and are
incorporated herein by this reference.
2. Declaration of Access Utility, and Emergency Services Easement. Declarant
hereby declares, grants, and conveys to the future owners of Lots 1, 2, and 3 an irrevocable,
nonexclusive and perpetual easement (the "Access Easement") over that portion of the Broadhurst
Minor Subdivision depicted on the Plat as “40’ Ingress/Access Utility and Emergency Services
Easement” for purposes of vehicular and pedestrian ingress and egress between Lots 1, 2, and 3
and County Road 107, primarily underground utilities necessary to serve each Lot, and for
www.sgm-inc.com
GLENWOOD SPRINGS 118 West Sixth St, Suite 200 | Glenwood Springs, CO 81601 | 970.945.1004
emergency services access, all as necessary or reasonably desirable in connection with the use,
ownership and enjoyment of Lots 1, 2, and 3 as a single-family residence. The Access Easement
may be used and enjoyed by the owners of Lots 1, 2, and 3, their successors and assigns. The
Access Easement shall be an easement appurtenant burdening the ownership of Lots 1, 2, and 3,
Broadhurst Minor Subdivision.
3. Use of Shared Roadway. It is expressly acknowledged and agreed that the Shared
Roadway may be used all owners of the Lots, their respective tenants, guests, licensees and
invitees, as the primary vehicular and pedestrian ingress and egress to and from each owner’s Lot
to County Road 107. All use of the Shared Roadway shall be conducted in such a manner so that
it does not unreasonably damage the Shared Roadway or any related improvement or unreasonably
interfere with the free right and enjoyment of the Shared Roadway by other users.
4. Maintenance of Shared Roadway. Each Lot Owner shall share equally the costs of
operating and maintaining the Shared Roadway, which costs shall include, but not necessarily be
limited to, snow removal, vegetation control, maintenance of signs, and operation and maintenance
of any and all ditches and drainage facilities related to the Shared Roadway. All Owners shall
have the authority to perform operation and maintenance activities on the Shared Roadway without
prior notice to the other party, except that in the event the cost of any act of operation or
maintenance upon the Shared Roadway is estimated to be more than $10,000.00 the party desiring
to undertake such work shall meet and confer with the other parties at least twenty (20) days in
advance of commencing such work, unless such work is necessitated by an emergency, in which
case the parties need only exercise good faith efforts to consult with one another prior to
commencing any emergency work. During the second calendar quarter of each year the parties
shall meet with one another, account for any work upon the Shared Roadway done by other parties
in the previous year, and financially reconcile between them so that the total cost of all work done
in the previous year is shared equally.
5. Damage to Roadway. In the event the Shared Roadway is damaged, and such
damage is caused solely by the negligence of a single Lot Owner, the Shared Roadway shall be
