Minor Subdivision Change of Zone
Questionnaire Narrative
Blue Sky Estates
Guy D. Jensen, Applicant
1. Consistency with Weld County Comprehensive Plan:
a. Goal 1 — Preservation of Prime Ag Lands. The property consists of approximately 20
acres upon which is one existing residence with the balance in portions of irrigated
alfalfa, pasture, roads, & waste. While this proposal will change the use to rural
residential, the applicant proposes to provide a pro-rata share of irrigation water from
the Slate Ditch to each of the proposed lots for purposes of irrigation of vegetative cover
and/or crops.
b. Policy 3 — Discouraging large-scale development outside of municipal boundaries. This
proposed subdivision is low density and not urban scale.
c. Goal 4 — Minimize impacts to farmland: The size of the existing parcel is small enough
to not be economically viable as a farm operation. The proposed use will not materially
affect ag production in the area or impact surrounding agricultural operations.
d. Policy 5 — Compatibility with existing surrounding land use: The proposed zoning
change is compatible with surrounding land uses as surrounding land owners are
primarily smaller farms and rural residences compatible with this development. The
property is currently used agriculturally however, due to the property size being 20
acres is not economically viable as a farm property due to its small size.
2. Compatibility With Surrounding Land Uses:
a. The proposed zoning change is compatible with surrounding land uses. Surrounding
landowners are primarily smaller farms and rural residences, which are compatible with
this development. The property is currently used agriculturally, however, due to the
property size being 20 acres it is not economically viable as a farm property. There are
presently nine properties adjacent to or within 500' the subject property. The following
is a list of those properties with owner's names, acreage of the parcels, and current
uses:
1.) Espinoza, Donaciano L. & Joann R. 36.62 Acres Rural Residential
2.) Funakoshi, Sam S. & Frances R. 114 Acres Farm
3.) Grabrian, Ronald & Sue Ann 75.12 Acres Dairy
4.) Grabrian, Ronald M. 1.88 Acres Rural Residential
5.) Hein, Richard L. 74.9 Acres Farm
6.) Koshio, Sam Mrs., Etal 77 Acres Farm
7.) Peterson, Mark Allen 5.01 Acres Rural Residential
8.) Sanchez, Nicandro & Maria E. 76.0 Acres Rural Residential
9.) Terry, Patricia 3.76 Acres Rural Residential
•
3. Sewer/ Septic Facilities:
a. Each of the lots will be served by individual sewage disposal systems (septics). The
systems will be permitted at the time a building permit is proposed and will need to meet
all engineering and other requirements of the Weld County Health Department at that
time.
4. Water Supply and Fire Protection:
a. The water requirements will be met by a public water system. The applicant has
purchased and paid for 4 water taps from The Central Weld Water District (see
attached documentation). The water taps have been installed on site.
b. The Fort Lupton Fire Protection District will provide fire protection. Concerns set forth in
the original referral letter from Larry Richardson, Ft. Lupton Fire Marshall, have been
addressed and satisfied per follow-up letter from Mr. Richardson.
5. Soil Limitations for Construction:
a. The subject property is composed of two soil types: Olney fine sandy loam, and Vona
loamy sand (see attached soil type descriptions). Both of these soil descriptions include
the following. "Soil has a good potential for urban and recreational development."
However, the Platte Valley Soil Conservation District has noted that Olney fine sandy
has moderate limitations for septic systems and the Vona loamy sand has severe
limitations for septic systems. The applicant proposes that the septic systems be
permitted at the time a building permit is proposed and will meet all engineering and
other requirements of the Weld County Health Department based upon soils and
percolation tests conducted at that time as a part of the septic permit applications.
6. Road & Highway Facilities:
a. The applicant will comply with conditions of approval as noted by Diane Houghtaling,
Traffic Engineer with the Weld County Public Works Department, as noted in her Weld
County Referral letter of 10/18/2000. (Please also see more detailed response under
comments of Weld County referral letter.) The applicant is requesting the temporary
use of the existing access to proposed Lot 1 (his personal residence) for as long as the
parcel continues ag production so as not to impact the land by construction of an
internal road from the proposed common property access to his home.
7. Mineral Resources:
a. The applicant has addressed the concerns of mineral owners as follows: written notice
has been made to all mineral interests. Dialogue has begun with the producers and
leaseholders as to final determination of surface agreements or other means to mitigate
the impact of the project to the mineral interests and to keep interference by and of
mineral exploration or production to a minimum. The applicant proposes a mutually
acceptable surface agreement with producers for access to existing facilities. The
applicant does not intend to pay for relinquishment of coal rights on the property since
the deposits are under 150 to 400 feet of overburden and the entire site is only 20 acres
in size and surrounded by rural residences, thus appearing to be not practical or
economically viable to recover.
8. Flood Overlay District: The property is not located in a Flood Overlay District.
9. Geologic Hazard Overlay District: The property is not located in a Geologic Hazard Overlay
District.
10. Airport Overlay District: The property is not located in an Airport Overlay District.

SITE DESCRIPTION:
This study was prepared for the proposed development for Lot 1,
2, 3, and Lot 4 of the proposed Blue Sky Estates, in the East ' of
the NE 'A of Section 35, T2N, R67W of the 6th Principal Meridian,
Weld County, CO.
This site is located on the north side of Weld County Road (WCR) 14.5 and
west of WCR 23.
This tract consists of 20.39 acres more or less. The existing site layout is
relatively flat with a gradual slope to the southeast corner of the lot. The
existing lot is vacant, with a few trees and grass/weed covered.
No major drainage ways exist on this property. The Slate Ditch borders the
site along the northerly boundary. Irrigation laterals run along the east and
south boundaries.
PURPOSE OF STUDY:
The drainage study was prepared for this site to store the storm water on the
site in a detention area. The drainage for the site will be stored in a storm
water detention pond located at the southeast corner of the site. This pond
will discharge to the south under WCR 14.5 into Little Dry Creek.
This drainage study was performed in accordance with the "Adams County
Storm Drainage Design and Technical Criteria Manual, February 1989".
PROJECT DESCRIPTION:
The project site encompasses Lots 1 to 4, which contains approximately
20.39 acres and is presently a series vacant lots, and approximately 5.0 acres
of offsite runoff.
The soils encountered on this site from the Soil Survey of Weld County, CO
by the USDA Soil Conservation Service is Olney and Vona. These soils
have a hydrologic group of"B", where low to moderate runoff volumes in
its historic state can be expected.
r
The project will consist of four residential homes, driveways, landscaped
areas and undeveloped areas as shown on the attached site map. The
composite percent impervious for the area is 6.8% for the site.
All runoff from the impervious areas shall be directed to the detention pond
located on the Southeast side of Lot 4 (see attached site map).
The detention pond will release water at the 10-year and 100-year historic
rates into the Little Dry Creek.
DRAINAGE BASINS:
The proposed development of the area has a single basin area. Surface
runoff from on and off site areas of the designated watershed shown on the
attached map are considered to be historic flow. The historic flow will
continue to infiltrate into the surface as it has in the past. A part of Lot A
(5.0 acres) is an off-site watershed that will contribute runoff to this project.
The storm runoff from this drainage basin will flow from the detention area
under WCR 14.5 in a 15-inch diameter CMP to drain into Little Dry Creek.
HYDRAULICS:
The outlet structure of the detention area will have a 15-inch diameter CMP
pipe to control the 10-year storm and 100-year storms. The existing 15-inch
diameter RCP pipe under the irrigation channel is sufficient to handle the
flows from the site. The maximum pipe flow is less than the allowed release
rate for the site.
HYDROLOGY:
The landscaped areas will carry the flow from the site. This storm runoff
will drain into the detention pond located on the Southeast corner of Lot 4.
The detention pond will have an outlet pipe to control the release rates to the
historical flows to under Weld County Road 14.5 to the Little Dry Creek.
CONCLUSION:
This drainage plan attempts to minimize the impact of the development of
this project on the surrounding properties. There will be a negligible
increase in storm flows from this site, however the drainage plan proposed
herein should effectively contain and control these flows at or below historic
rates.

ADAMS COUNTY
STORM DRAINAGE DESIGN AND TECHNICAL CRITERIA
CHAPTER 14 DETENTION
14 . 1 INTRODUCTION
The criteria presented in this section shall be used in the design and
evaluation of all detention facilities. The review of all planning submittals
(refer to Chapter 2) will be based on the criteria presented in this section.
The main purpose of a detention facility is to store the excess storm runoff
associated with an increased basin imperviousness and discharge this excess at a
rate similar to the rate experienced from the basin without development. The
value of such detention facilities is discussed in (Section 3.3.6. Any special
design conditions which cannot be defined by these CRITERIA shall be reviewed by
the Director of Engineering before proceeding with design.
14.2 DETENTION METHODS
The various detention methods are defined on the basis of where the facility
is constructed, such as open space detention, parking lot, underground or roof-
top. The County permits all methods of detention except for rooftop
(POLICY 3.3.6) .
14.3 DESIGN CRITERIA
14.3.1 Volume and Release Rates
The minimum required volume shall be determined using the CUHP method or the
following equations. These empirical equations were developed as part of the
UD&FCD hydrology research program. The equations are based on a computer model-
ing study and represent average conditions. One of the most difficult aspects of
storm drainage is obtaining consistent results between various methods for
estimating detention requirements. These equations will provide consistent and
more effective approaches to the sizing cf onsite detention ponds. For larger
water sheds where the Colorado Urban Hydrograph procedure can be used (i.e. , ±90
acres) , hydrograph routing procedures will be permitted in the design of these
ponds, provided the historic imperviousness of two percent or less is used.
Minimum Detention Volume:
V = KA
(Equation 1404)
For the 100 year,
1'100 - (1.781 - 0.00212 - 3.56)/1000 (Equation 1405)
For the 10 year,
K10 = (0.951 - 1.90)/1000 (Equation 1406)
Where V = required volume for the 100 or 10 year storm (acre-feet)

A = Tributary area (Acres)
The maximum release rates at the ponding depths corresponding t„ the 10
and 100 ,year- volumes are as follows:

10 year 0.13 0.23 0.30 _.
100 year 0.50 0.85 1.00
The predominate soil group for the total basin area tributary to the
detention pond shall be used for determining the allowable release rate„
Information on the soils in the County can be found in Reference 25,
14.3.2 Design Frequency
All detention facilities are to be designed for two storm frequencies: the
10 year and the 100 year recurrence interval floods.
14.3.3 Hydraulic Design
Hydraulic design data for sizing of detention facilities outlet works is as
follows:
1. Weir flow
The general form of the equation for horizontal crested weirs is:
Q = CLH3/2
(Equation 1401)
Where Q = discharge (cfs)
C = weir coefficient
(Table 1401)
L = horizontal length (feet)
H = total energy head (feet)
Another common weir is the v-notch, whose equation is as follows:
Q = 2.5 tan (0/2)135/2 (Equation 1402)
Where 0 = angle of the notch at the apex (degrees)
When designing or evaluating weir flow, the effects of submergence must be
considered. A single check on submergence can be made by comparing the
tailwater to the headwater depth. The example calculation for a weir design
on Figure 1403 illustrates the submergence check.

2„ Orifice Flow
The equation governing the orifice opening and plate is the orifice flow
equation
- d (2gh) / (Equation !Lips)
Where !) Flow (,:ft.)
Cd -. Oilflue coefficient
A = Area (ft2)
g = Gravitational constant = 32.2 ft/sec`
h = Head on orifice measured from centerline of orifice (ft )
An orifice coefficient (C-sub d) value of 0.65 shall be used for sizing or
square edged orifice openings and plates.
14.4 DESIGN STANDARDS FOR OPEN SPACE DETENTION
14.4.1 State Engineer's Office
Any dam constructed for the purpose of storing water, with a surface area,
volume, or dam height as specified in Colorado Revised Statues 37-87-105 as
amended, shall require the approval of the plans by the State Engineer's Office.
All detention storage areas shall be designed and constructed in accordance with
these CRITERIA. Those facilities subject to state statutes shall be designed and
constructed in accordance with the criteria of the state.
14.4.2 Grading Requirements
Slopes on earthern embankments less than 5 feet in height shall not be
steeper than 4 (horizontal) to 1 (vertical) . For embankment heights between
5 feet and 10 feet, the slopes shall not be steeper than 3 (horizontal) to 1
(vertical) , but the horizontal distance of the slope shall not be less than
20 feet. For embankments greater than 10 feet in height, the slopes shall be
such to maintain slope stability, but the horizontal distance of the slope shall
not be less than 30 feet. Contact the Director of Engineering for additional
requirements for embankments greater than 10 feet in height. All earthen slopes
shall be covered with topsoil and revegetated with grass. Slopes on riprapped
earthern embankments shall not be steeper than 3 (horizontal) to 1 (vertical) .
For grassed detention facilities, the minimum bottom slope shall be 0.5 percent
measured perpendicular to the trickle channel.
14.4.3 Freeboard Requirements
The minimum required freeboard for open space detention facilities is
1 .0 foot above the computed 100 year water surface elevation.
14.4.4 Trickle Flow Control
All grassed bottom detention ponds shall include a concrete trickle channel
or equivalent performing materials and design. Trickle flow criteria is
presented in Section 7.4.2.6(a) , page 7-5.
