SCOPE
This report provides percolation test results and septic system recommendations for the
proposed new residential home to be located at 5300 Kiowa Drive, Weld County, Colorado. It is our
understanding that this system will service a four (4) bedroom residence, with no future expansion
planned at this time. The wastewater strength is anticipated to be typical for a single family
residence using standard household appliances and fixtures.
SITE INVESTIGATION
A field investigation, performed on October 15, 2015, consisted of drilling one (1) profile
hole to a depth of eight (8) feet and three (3) percolation holes ranging in depth from thirty-three to
thirty-four (33-34 ) inches. Percolation tests were performed on October 16, 2015. The Location of
the Test Holes is shown on Drawing No. 1A. A Log of Borings is shown on Figure No. 2. The
descriptions of the soils are based, primarily, on visual and tactual methods which are subject to
interpretation.
The percolation test area was established by a representative of CDS Engineering
Corporation based on stakes provided by the homeowner, Distances from the referenced features
were made by taping and angles were estimated.
Other than the distances to setback objects indicated on the design documents, no other
objects requiring setbacks from the proposed on -site wastewater treatment system (OWTS), as
indicated in Tables 30-7-1 and 30-7-2 of the Weld County Regulations, have been located or
observed during our exploration.
SI I LOCATION AND DESCRIPTION
The site is located south of Greeley, south of 3711' Street, east of Arrowhead Drive, at the
east end of Kiowa Drive, Weld County, Colorado. The site is in a developed rural subdivision
with paved roads and utilities, and vegetation consists primarily of grasses. The building site has
a gentle to moderate slope to the northeast, No rock outcrops or water wells were observed at
this site. Historically, this site appears to have not been developed. A small creek and a
2
wetlands area were observed approximately 150 feet to the north. In addition, the floodplain is
located 10 feet east of the proposed septic field site.
Based on a site plan easements are not noted on the property. However, we recommend title
work be completed prior to construction to ensure the property is clear of easements. From
information provided on the County Property Information Portal Maps, part of this property is
located in a floodplain; and there are no right-of-way setbacks that would affect the proposed
placement of the on -site wastewater treatment system.
SUBSOILS AND GROUNDWATER CONDITIONS
Based on the profile boring drilled within the proposed soil treatment area, the subsurface
conditions at the site consist of six (6) feet of silty sand overlying a siltstone/claystone bedrock strata
Groundwater levels were recorded as the borings were advanced, after completion of the
drilling operations and twenty-four (24) hours after the drilling operations. During our field
explorations groundwater was not encountered in the profile hole. We do not anticipate the high
groundwater level to be within four (4) feet of the infiltrative surface.
PERCOLATION TEST RESULTS
A total of three (3) percolation tests were conducted on the site, using the Standard Test
Method, as described by the Weld County Health Department, Percolation test holes were presoaked
on October 15, 2015, and the test was performed on October 16, 2015.
The percolation exploration indicated percolation rates of 40, 24, and 40 minutes per inch
with an average percolation rate of 35 minutes per inch. Based on the conditions described above, a
standard absorption system should be suitable for this site; however, due to the depth of the bedrock,
the bottom of the bed shall be no deeper than two (2) feet below original grades.
3
MA 1'bRIALS
The materials used in construction of the on -site wastewater treatment system shall be new,
durable and not subject to corrosion, such as concrete, fiberglass or plastic. All materials shall be
installed per manufacturer specifications. All connections between components shall be water tight
to prevent leaks and infiltration,
Piping
Unperforated plastic pipe used in gravity flow beds shall have a nominal diameter of four (4)
inches, and a wall thickness of 0.120 inches, or greater. SDR 35 or Schedule 40 pipe could
be used. The piping from the building to the septic tank, and from the tank to the field shall
have a minimum fall of/S-inch per foot ('A inch per foot preferred). Perforated piping used
in the absorption bed or trench shall have a minimum nominal diameter of three (3) inches,
and a wall thickness of 0.70 inches, or greater. ASTM D2729 sewer and drain pipe is
acceptable for this application. Pipe laid in beds or trenches shall be laid level. The terminal
ends of all lines shall be capped or looped with all other lines in the system. Pipe bends shall
be limited to 45 degrees or sweeping 90 degree "L"s. Building sewer and effluent lines shall
be buried a minimum of one (1) foot. All pipe bedding and trench compaction shall be in
accordance with the manufacturer guidelines.
Septic Tank
Septic tanks shall meet the provisions set forth in the county on -site wastewater treatment
regulations, and be constructed in accordance with ASTM C 1227. Tanks shall be placed a
minimum of five (5) feet from any dwelling or building with a permanent foundation. The
tank shall have a minimum of two (2) compartments. Tank size is based on design flow. See
Drawing No. 2 for specific tank size. The tank lid shall be able to support a minimum oftwo
(2) feet of soil cover. Tank manufacturer shall provide specifications on maximum cover
depth and other design features. These should be provided to the engineer prior to delivery.
Access risers shall be provided for each compartment of the septic tank. Risers shall have a
minimum 24 -inch diameter and extend to, or above, ground level. Riser lids shall have a
secure closing mechanism to prevent unauthorized access. Tanks should be sold and
delivered by the manufacturer or manufacturer's representative.
4
Distribution Box
Distribution boxes shall be placed on solid, level ground to provide uniform distribution of
the effluent. The box shall be a minimum of five (5) feet from the septic tank, and be
sufficient size to provide outlets for all lateral lines, otherwise additional distribution boxes
may be required. Outlet lines shall consist of solid pipe (see piping) for a minimum of five
(5) feet, Access to the distribution box shall be provided by a riser, similar to that described
for septic tanks.
ABSORPTION FIELD
The absorption field shall be placed a minimum of twenty (20) feet from occupied or
habitable structures or structures with permanent foundations. The field shall be constructed in
accordance with this report and the drawings provided. The infiltrative surface and distribution
lines, or chambers, must be level.
Trenches shall be no wider than three (3) feet; beds shall be no wider than twelve (12) feet.
Evapotranspiration Absorption beds are exempt for this requirement. Beds and trenches shall be
separated by six (6) feet, of undisturbed soil.
Inspection ports, accessible from the ground surface must be installed at the terminal end of
each line. The inspection port tube must extend to the bottom of the infiltrative surface and not be
connected to the end of the distribution pipe. Where chambers are used, the inspection ports shall be
installed per the manufacturer's recommendations, at the end of each line.
See Drawing No. 1B for information specific to this project.
BACKFILLING AND SITE GRADING
All major grading shall be accomplished before construction of the sewage disposal system.
Backfilling around septic tanks shall be accomplished before the installation of the piping, Backfill
around the tank shall be in a manner to prevent settlement and avoid undue strain on the tank.
Positive drainage from, and around, the bed must be provided by sloping, mounding, ditching or
berming.
5
CONCLUSIONS
The system should be constructed by a licensed septic system installer, in accordance with the
County On -Site Wastewater Treatment Regulations. An effluent filter could be installed in or after
the septic tank and may provide a longer life for the system. Minimum dimensions and setback
requirements specified by the state or county health department regulations shall be upheld. It is the
contractor's/owner's responsibility to inform the engineer or health department of anything not
mentioned in this report that may impact the performance of the septic system. This system is to
meet all rules and regulations set forth by the County Health Department. The system is to be
inspected by a representative of the County Health Department and Engineer, prior to backfilling.
All future owners are to be directed to information in Appendix I (General Maintenance
Recommendations) of this report. These tests are only valid for the areas tested. Additional
percolation tests and soil profile information will be required if the septic system is to be constructed
in a different location than covered by this exploration. The findings and recommendations of this
report have been obtained in accordance with accepted engineering practices in the field of
Geotechnical Engineering. There is no other warranty, either expressed or implied. The county
health depai anent has final acceptance over these test results and referenced system. All
construction shall be in compliance with the septic system permit.

APPENDIX I
GENERAL MAINTENANCE RECOMMENDATIONS FOR
INDIVIDUAL SEWAGE DISPOSAL SYSTEMS
The following minimum recommendations, if followed, should help increase the lifetime of the
system:
1. Septic tanks should be pumped as often as needed based on usage. Generally when
the scum layer plus the sludge layer equals 25% of the liquid depth in the tanks, it
should be pumped out.
2. Septic tanks and distribution boxes should be checked at least once a year for sludge
accumulation which may clog the leach area if overflow occurs.
3. The leach area should not be used for grazing, sports activities, traffic, or other
activity which may compact the soils.
4. Schedule 80 pipe should be used if lines are to be placed under driveways.
5. Trees should not be planted within 10 feet of the leach area so as to prevent roots
from clogging the system.
6. If trees are to be planted nearby, they should be located so that the leach area is not
shaded.
7. Overuse of strong chemicals, which may kill the bacteria in the system and inhibit
decomposition of the sewage, should be avoided.
8. Positive drainage should be maintained over and around the absorption field area to
prevent pooling of water.

MINUTES OF THE WELD COUNTY UTILITIES ADVISORY COMMITTEE
A regular meeting of the Weld County Utilities Coordinating Advisory Committee was held on Thursday,
January 8, 2015 at 10:00 a.m., in the Hearing Room of the Weld County Planning Department at 1555 N 17th
Ave, Greeley, Colorado.
Members Present: Galen Monson, Richard Hastings, Jennifer Petrik, LeAnn Koons, Robert Fleck and
Jerry Adams
Members Absent: Terry Stencel, Terry Speer, Tom Beach, and Al Trujillo
Also Present: Chris Gathman, Department of Planning Services and Kris Ranslem, Secretary.
CASE NUMBER: RES14-0001
APPLICANT: LAKE ARROWHEAD INC.
PLANNER: CHRIS GATHMAN
REQUEST: APPLICATION FOR A RESUBDIVISION TO DIVIDE TRACT A OF ARROWHEAD
SUBDIVISION 4TH FILING INTO TWO LOTS. THIS APPLICATION IS BEING
PROCESSED IN CONJUNCTION WITH CHANGE OF ZONE COZ14-0005.
LEGAL DESCRIPTION: TRACT A ARROWHEAD 4TH FILING; LOCATED IN PART OF THE N2 OF
SECTION 27, T5N, R66W OF THE 6TH P.M., WELD COUNTY, COLORADO.
LOCATION: SOUTH OF AND ADJACENT TO WEST 37TH STREET AND APPROXIMATELY
1,500 FEET WEST OF 47TH AVENUE.
Chris Gathman, Planning Services, stated that the applicants are applying to divide Tract A into two (2) lots,
approximately 5.3 acres each in size. A good portion of the property is in the floodway/floodplain. Mr.
Gathman noted that there was a previous application for this tract of land in 1998 and was presented to the
Utility Board. He was unable to find minutes from the Utility Board but did find minutes from the Board of
County Commissioner hearing. In the minutes, the County Commissioners talked about providing a 15 foot
drainage and utility easement to the back of the property as well as another 15 foot drainage and utility
easement between the two lots, one by the road and another one by the cul de sac.
Mr. Gathman stated that staff recommended: 1) keeping the existing platted easements for Tract A delineated
on the Arrowhead Fourth Filing plat 2) delineating a 15 foot drainage and utility easement along Kiowa Drive;
3) delineating a 15 foot utility easement along that section of Pawnee Drive that doesn't presently have an
easement; and 4) Delineating a 10 utility easement along Tract Al Lot 1 boundary, which is located on the
southeastern portion of the site.
Jerry Adams said that he was not sure where the 10 foot easement was that staff noted. Mr. Gathman said
the original map did not show it; however it appears that the applicants have identified it on the proposed map.
Jerry asked that the utility signature block be included on the plat according to Section 27-9-40.B so affected
utilities will have a chance to see it and sign off on it.
Mr. Gathman said that the standard for a new lot line is the required 10 foot on either side of that property line.
He added that this property line will be running right through the floodplain area. He further added that 37th
Avenue along the north side has no easement. Mr. Adams asked the Utility Board if they see any need of
keeping the required 20 foot easement. Mr. Adams felt that it could be useful as an access way from
Arrowhead out to 37th Avenue. The Utility Board agreed with that. Eric Wernsman, applicant's representative,
asked if it could be identified as a utility/drainage easement. The Utility Board agreed with that suggestion.
Mr. Adams summarized the changes by incorporating all the staff recommendations 1-4, delineate 20 foot
utility and drainage easement apportioned equally between Lots 1 and 2, along the proposed lot line and add
the Utility's Service Statement Block to the plat. The motion was made by Robert Fleck, seconded by Rich
Hastings.
Meeting adjourned at 10:19 a.m.
Respectfully submitted,
Kristine Ranslem
Secretary
