FROM: Mike McRoberts, P.E., Development Review
DATE: October 29, 2021
SUBJECT: SUBJECT: PUDZ21-0003 DOB Farm PUD
This proposal has been reviewed by Development Review on behalf of the Weld County Department of
Public Works. Staff comments made during this phase of the application process may not be all-inclusive,
as other issues may arise during the remaining application process.
COMMENTS
GENERAL PROJECT INFORMATION/LOCATION
Project description: Change of Zone Request from the A (Agricultural) Zone District to the PUD (Planned
Unit Development) Zone District for three (3) residential lots with Estate Zone District Use, and on -going oil
and gas activities.
Parcel number 105508300052
Proposed Development Access is from CR 39.
ACCESS
Development Review has reviewed the application materials related to access.
The applicant is proposing that the existing permitted access location (AP18-00815 — Residential) onto
County Road 39 be re -permitted as the "development access" for the proposed PUD's internal roadway.
This location does not meet the minimum access spacing criteria specified in Table 1 below (PUD accesses
are classified as intersections). However, no location along the parcel's County Road 39 frontage will meet
the foregoing spacing criteria. For which reason, Development Review will accept the proposed intersection
location. No access variance is needed.

Per Sec. 8-14-30.G., when there is a change in use of the access classification/type, or an increase in the
amount of traffic using an access, a new access permit shall be required as a condition of the change in
use.
ROADS AND RIGHTS -OF -WAY
County Road 39 is a paved road and is designated on the Weld County Functional Classification Map (Code
Ordinance 2017-01) as a collector road, which requires 80 feet of right-of-way. The applicant shall delineate
and label on the plat the existing and future rights -of -way and the physical location of the road. The creating
documents for the existing right-of-way shall be provided on the plat. If the right-of-way cannot be verified
it shall be dedicated or reserved per Weld County Code. Pursuant to the definition of setback in the Weld
County Code, Sec. 23-1-90, the required setback is measured from the future right-of-way line. Be aware
that physical roadways may not be centered in the right-of-way. This road is maintained by Weld County.
Per Section 8-13-30.8, a Weld County Right -of -Way Use Permit is required for any project that will be
occupying, constructing or excavating facilities within, and/or encroaching upon, any County rights -of -way

Weld County will not replace overlapping easements located within existing right-of-way or pay to relocate
existing utilities within the County right-of-way.
TRAFFIC
Latest ADT on CR 39 counted 1,697 average daily trips with 21% trucks. The 8511 percentile speed is 59
mph.
According to the applicant's traffic narrative, Lots 1 and 2 will have a combined total of 4 daily roundtrips of
passenger vehicles, while Lot 3 will have approximately 2 pickup truck or tractor roundtrips per day.
The applicant shall submit a revised Traffic Narrative if the intended use of Lot 3 has changed since the
original traffic narrative was submitted. Note: The Institute of Transportation Engineers' Trip Generation

Memorandum
To: Diana Aungst
From: Lauren Light, Environmental Health Services
Date: September 29, 2021
Re: PUDZ21 -0003 DOB Farm LLC
Environmental Health Services has reviewed this Change of Zone Request from the A
(Agricultural) Zone District to the PUD (Planned Unit Development) Zone District for two
(2) residential lots with Estate Zone District Use, one (1) lot with Agricultural Zone
District Uses (limited to a Solar Energy Facility), and on -going oil and gas activities.
Central Weld County Water District will provide water and on -site wastewater treatment
systems (OWTS) will provide sewer service. Engineer designed OWTS may be
required due to the slow filtration rate of the soil on the site.
Outstanding items identified from PUDK19-0004 have been addressed with this
submittal. A report from Earth Engineering Company, Inc., dated June 10, 2019, was
submitted. Environmental impacts were satisfactorily addressed.
We recommend the following appear as notes on the Change of Zone plat:
1. Water service may be obtained from Central Weld County Water District.
2. The parcel is currently not served by a municipal sanitary sewer system.
Sewage disposal may be by on -site wastewater treatment systems (OWTS)
designed in accordance with the regulations of the Colorado Department of
Public Health and Environment, Water Quality Control Division, and the Weld
County Code in effect at the time of construction, repair, replacement, or
modification of the system.
3. Activity or use on the surface of the ground over any part of the OWTS must be
restricted to that which shall allow the system to function as designed and which
shall not contribute to compaction of the soil or to structural loading detrimental
to the structural integrity or capability of the component to function as designed.
4. During development of the site, all land disturbances shall be conducted so that
nuisance conditions are not created. If dust emissions create nuisance
conditions, at the request of Weld County Environmental Health Services, a
fugitive dust control plan must be submitted.

RE: Case Number PUDK19-0004
Dear Diana:
We have reviewed the application by D.O.B. Farm, LLC for PUDK 19-0004 and have the following comments:
Weld County School District RE -1 has developed methodology for Land Dedication and/or In Lieu Payments. The current In Lieu
Payment amount per single family unit is $1,054.20. Based on the information provided, it appears that there are plans to create 3 new
lots on the parcel. Therefore, an in lieu payment in the amount of $3,162.60 is due to the school district prior to approval of the recorded
exemption. The district is requiring that D.O.B. Farms make sure they follow the recommendation of the local fire protection district on
the required width of road so that a fire truck and/or a school bus can safely turn around in the roadway. If you have any further questions
please feel free to contact me.
Respectfully,
Doug Moss

Joe,
I appreciated our conversation this morning. Per your request I wanted to clarify some of the details that were included in your letter to the county which I have attached. As a reference I have
also attached a map which we recently provided to the county which shows approximate locations of the proposed structures and access points.
1. Water supply - With this being a small 3 lot PUD we were hoping to avoid the expense of a dedicated hydrant. I believe you were planning to have the captain determine where the closest
hydrant is located or if a tender shuttle might suffice. As I mentioned we do also have a drainage ditch that adjoins the property in the southeast corner, and which usually has water
flowing year-round, so perhaps that could suffice?
2. Access roads —The details about what is required in terms of the "150 feet without a turnaround.." would be helpful to us.
3. Road — I believe you had stated that paving would not be required, and that road base would suffice?
I have cc'd my brother DeWayne on this since we are partners on this project. It probably would be beneficial for someone from the Fire Department to meet us at the site, and if that is desired
just let us know.
Thanks, Daryl Bohlender(970-216-4908)

Daryl, after talking to the Fire Chief he will accept residential fire sprinkler systems for the homes instead of the required fire hydrant systems. The the access roads will still be required and will need to be installed
before construction of the homes. Please give me a call if you have any questions about the fire sprinkler systems.

Good morning Joe,
Mon, Jan 25, 11:57 AM
We appreciate your response about the residential fire sprinkler systems in the homes. Regarding the access roads, you have mentioned during a phone conversation that we had a few months ago that
there is a requirement for "150 feet without a turnaround." I guess I'm still a little unclear what that means, so if that could be explained further it would be helpful to us.
Thanks, Daryl

Joe,
Just to confirm our phone conversation:
Mon, Jan 25, 2:41 PM
• If the residences have a "fire sprinkler system", there would not be a requirement for the 150 foot turnaround, correct?
• Regarding sprinkler systems I would anticipate a complete residential fire sprinkler system could be quite costly. You had mentioned that there are a variety of sprinkler system options (separate water tanks, etc),
which I would appreciate learning more about. Is there any information you could send me? Or should we schedule a time to connect and discuss?
Thanks!

Hey Joe,
I'm just checking in to see if you got the answers to my last email?
Thanks, Daryl
DeWayne Bohiender<drbohlender@gmaH.com>

FYI, per my research, adding a home sprinkler system only adds about $1.501 sq foot. So at that (if correct)
a 2000 sq ft house would only be $3000. Worth the protection.

Case No. PUDZ21-0003
Part of the NW 1/4 SW 1/4 of Sec. 8, T4N, R65W, 6th P.M.
Water Division 1, Water District 2
Dear Diana Aungst:
We have reviewed the September 20, 2021 proposal to subdivide and rezone a 15.28 -acre parcel
known as Lot A of Amended Recorded Exemption 1AMRECX20-08-4792 into 3 lots. Lots 1 and 2 will
be approximately 2 acres and be used as residential lots. Lot 3 will be approximately 10.05 acres
and be leased for used for agricultural uses, including use as a solar farm and for on -going oil and
gas activities. This office previously provided comments for this planned unit development on March
23, 2020 (case no. PU DK19-0004).
Water Supply Demand
According to the Water Supply Information Summary provided by the applicant on October 1, 2020,
the proposed water use and estimated demand for the residential lots are as follows: 0.3 acre-
feet/year for household use, 0.25 acre-feet/year for irrigation use, and 0.1 acre-feet/year for the
watering of livestock, for a total of 1.3 acre-feet/year for both residential lots. No water demand
or water uses for Lot 3 was specified.
Source of Water Supply
The proposed water supply is service provided by the Central Weld County Water District (CWCWD).
According to the letter dated May 24, 2021, the CWCWD can serve the development provided that
all requirements set forth by the CWCWD are met. According to an email dated May 26, 2021 from
Kathy Naibauer, this parcel has met these requirements to be eligible to receive service from the
CWCWD.
The CWCWD provided information about their water supplies in September of 2018. The CWCWD
primarily relies on Colorado -Big Thompson (C -BT) water to supply retail water customers. As of
September 2018, the CWCWD owned 5,832 C -BT units and 100 Windy Gap units. The yield of C -BT
units and Windy Gap units varies from year to year based on conditions and storage. The dry year
water yield is 3,800 acre-feet per year and the average yield is 4,800 acre-feet. In addition, the
CWCWD continues to develop additional water supplies, including participating in the Northern
Integrated Supply Project (NISP). According to the CWCWD, their current demand is 5,500 units
with a commitment to serve 31 additional units.
A review of our records showed well permit no. 11272-R located on the subject property. This well
was registered on April 7, 1960 as an existing well used for irrigation and withdrawing from the
alluvium. This well was later decreed as Kaufmen Well No. 2-11272 in Division 1 Water Court case

covered under a water court -approved augmentation plan, a measuring device is installed, and a
well test is performed by a certified well tester and submitted to the Division of Water Resources.
State Engineer's Office Opinion
Based upon the above and pursuant to section 30-28-136(1)(h)(I), C.R.S. and section 30-28-
136(1)(h)(II), C.R.S., the State Engineer's Office offers the opinion that the proposed water supply
can be provided without causing material injury to existing water rights and the supply is expected
to be adequate.

Subject: PUDZ21-0003 — DOB Farm Change of Zone to PUD
Weld County, Colorado; CGS Unique No. WE -20-0028-3
Dear Diana:
Karen Berry
State Geologist
Colorado Geological Survey has reviewed the DOB Farm Change of Zonc referral. I understand the applicant
currently proposes a Change of Zone from the A (Agricultural) Zone District to the PUD (Planned Unit
Development) Zonc District for two residential lots with Estate Zone District Use, one lot with Agricultural
Zone District Uses (limited to a Solar Energy Facility), and ongoing oil and gas activities. The referral
documents include a Geologic Hazards and Mineral Extraction Evaluation Report, Proposed 3 -Lot PUD,
22240 County Road 39, La Salle (Earth Engineering Company, Inc. [EEC], June 18, 2019). CGS reviewed
this site and EEC's 6/18/2019 report at PUD sketch plan in March 2020 (PUDK19-0004). The proposed PUD
is substantially the same as previously rcvicwcd.
The site is not undermined, is in an "Area of Minimal Flood Hazard," and is not exposed to any known or
suspected geologic hazards that would preclude the proposed residential and solar uses. CGS therefore has no
objection to approval of the PUD as proposed. Our March 2020 comments remain valid:
EEC's Geologic Hazards and Mineral Extraction Evaluation Report contains a very general description of site
geology and mineral resource potential based on available geologic mapping and NRCS soil survey data, which
is typically valid for only the uppermost five feet below the ground surface.
Mineral resource potential. According to the Atlas of Sand, Gravel, and Quarry Aggregate Resources,
Colorado Front Range Counties (Schwochow et al, Colorado Geological Survey Special Publications 5-A,
Plate 2, and 5-B, La Salle Quadrangle, 1974), the subject property is located near the southern edge of a
mapped "T3" resource area. As noted by EEC (page 5) T3 is described as a stream terrace deposit potentially
containing a sand resource.
A depression shown on the La Salle quadrangle in the eastern portion of proposed Lots 1 & 2 and west of the
Western Mutual Ditch indicates that some resource extraction may have already occurred, possibly related to
construction of the ditch. The site's location near the edge of the mapped resource area indicates that any
potential aggregate layer may be relatively thin. A determination of whether the property contains an
economic mineral resource is outside the scope of CGS review. A site -specific investigation would be
required to verify the presence or absence of a mineral resource.
Potential geologic and geotechnical constraints. The site is underlain by Broadway alluvium (South Platte
River -deposited sand and gravel). This soil type is typically not problematic from a geotechnical, or

foundation performance perspective. The surficial soils arc underlain at unknown depth by the Laramie
Formation, consisting of potentially highly expansive shales and claystones interbedded with non -expansive
sandstones, coal beds and lignites. Shales and claystones can exhibit significant volume changes in response
to changes in water content. Expansive shale and claystone layers and lenses within a few feet of foundation
bearing elevations can cause structural damage if not identified and mitigated. Perched water and shallow
groundwater may be present or may develop post -construction.
Corrosive soils. Although not discussed by Soilogic, NRCS Soil Survey data indicate that the site soils are
moderately corrosive to uncoated steel. Disturbance tends to increase corrosivity. Epoxy -coated,
fiberglass/composite, concrete, or otherwise corrosion -resistant or corrosion -proof basement window wells
are recommended on lots where basements are planned and are determined to be feasible.
Lot -specific gcotechnical investigation, testing, and analysis will be needed, once building locations have been
determined and prior to building permit application, to (1) determine depths to bedrock and seasonal
groundwater levels, (2) characterize soil and bedrock engineering properties such as density, strength, water
content, and swell and consolidation/hydrocompaction potential, (3) evaluate the need for overexcavation or
other mitigation measures to address potentially moisture -sensitive (expansive and collapsible) soils, expansive
claystone bedrock and soft, low -strength lignite, (4) provide earthwork, foundation, floor system, subsurface
drainage, and pavement recommendations for design, and (5) determine each lot's suitability for below -grade
(basement) construction, if planned.
