VI C FROM: Don Dunker, P.E., Public Works JJt
COLORADO SUBJECT: AmPZ-512, George Bollinger
The Weld County Public Works Department has reviewed this proposal. Our comments and requirements are
as follows:
COMMENTS:
WCR 43 is a paved collector road and requires an 80-foot right-of-way at full build out. There is presently a 60-
foot right-of-way. This road is maintained by Weld County. Pursuant to the definition of SETBACK in the Weld
County Zoning (23-1-90), the required setback is measured from the future right-of-way line.
Traffic counts taken 04/20/06 on WCR 43 just north of WCR 72 indicated there were an average of 1,205
vehicles per day traveling on the road.
The applicant shall reserve or dedicate an additional 10-foot right-of-way parallel to the WCR 43 right-of-way
for future build-out.
SEQUIREMENTS:
The applicant shall indicate specifically on the plat the type of right-of-way/easement and indicate whether it is
dedicated, private, or deeded to provide adequate access to the parcel. Section line accesses are considered
private lanes with no county maintenance.
The construction of the access easement for outlot C shall not create any above grade features, data shall be
supplied (stamped and signed) from a registered Professional Land Surveyor licensed to practice within the
State of Colorado that the new access roadway was placed at the historic grade elevation. Should the access
road be elevated above historic grade elevation a Flood Hazard Development Permit (FHDP) will be required.
Please contact Brian Varrella at (970) 304-6496 for more details.
It may create less confusion if this access easement within oulot A were to be part of the property boundary for
newly created residential lot, outlot C.
The access road for outlot C shall be placed in such a location to have adequate sight distance in both
directions. Provide documentation that the curve radius is adequate for semi-truck traffic. A 40' radius is
required on all accesses to public roads for accesses to accommodate truck traffic. {A minimum effective
turning radius of forty-feet (40') shall be used for accesses to accommodate truck traffic. (Weld County
Codification Ordinance 2000-1)} Sec. 8-2-40 B. Road access design standards.
Place a stop sign to stop traffic as the easement for outlot C intersects into Avery Drive. Place no parking
signs at the entrance of the easement for outlot C along Avery Drive.
•rovide data that there is enough distance away from the adjacent driveway from lot 1 for safe access to the
easement for outlot C.

dd the following note to the plat, "Lot owners shall be informed that a crop dusting facility is located directly
iiprth of the Avery Acres PUD. It is legally permitted through Use By Special Review Permit #814 and is
eligible to apply for expansion and may create substantial noise associated with the operation."
Stormwater:
Please place the Federal Emergency Management Agency (FEMA) regulatory floodplain limits for Lone Tree
Creek on the plat.
Portions of outlot C are within the 100-year floodplain limits of Lone Tree Creek. These areas shall be labeled
as "No Build Zones only for agriculturally exempt, non-insurable facilities", and indicated as open space on the
plat.
Per the Drainage Report letter from McRae and Short, Inc, dated October 21, 1998, stamped and signed by
Gerald B. McRae P.E. 6616, the Avery Acres Subdivision for five lots and access road off WCR 43 do not
require detention. The addition of outlot C as a residential lot to the Avery Acres Subdivision will not require a
drainage report since the percent impervious will be less than the existing lots with there respective
improvements.
If a drainage culvert is required, a 15-inch diameter pipe is the County's minimum size requirement. If the
applicant chooses to place a larger culvert, please adequately size your culvert using appropriated engineering
design calculations. No berming is allowed within the 100-year FEMA regulatory floodplain.
Utilize the existing agricultural, oil and gas, and ditch roads that are necessary for your agricultural operation.
"Pursuant to Chapter 15, Articles I and II of the Weld County Code, if noxious weeds exist on the property or
ecome established as a result of the proposed development, the applicant/landowner shall be responsible for
controlling the noxious weeds.
This property IS in FEMA Flood Zones.
A portion of AmPZ-521 property lies in a Zone-A Special Flood Hazard Area (SFHA) defined by the FEMA.
This SFHA is delineated on the current effective Flood Insurance Rating Map (FIRM), panel number 080266
0489 C, dated September 28, 1982. Portions of lots located in the current effective FEMA 100-yr floodplain
may not be buildable.
Add the following to the Plat: "WARNING: LOTS MAY NOT BE BUILDABLE DUE TO FLOODPLAIN OR
FLOODWAY DESIGNATION. THE ACCESS ROAD TO THIS LOT IS WITHIN THE FEMA REGULATORY
FLOODPLAIN LIMITS FOR LONE TREE CREEK AND MAY NOT BE PASSABLE DURING A 100-YEAR
STORM EVENT. Please be advised that owners of outlot C may not be able to obtain building permits to
construct non-agricultural structures. All construction or improvements occurring in the floodplain as
delineated on Federal Emergency Management Agency FIRM Community Panel Map 080266 0489 C dated
September 28, 1982, shall comply with the Flood Hazard Overlay District requirements of Chapter 23, Article
V, Division 3 of the Weld County Code and all applicable FEMA regulations and requirements as described in
44 CFR parts 59 and 60."

DATE: December 10, 2007 111 D C FROM: Pam Smith, W.C. Department of Public
COLORADO Health and Environment
CASE NO.: AmPZ-512 NAME: George Bollinger
The Weld County Health Department has reviewed this proposal. The proposed amendment to the Avery
Acres PUD is to add an additional residential lot(labeled Outlot C) north of the existing Lot 1 and to vacate
that portion of the existing Outlot A south of Avery Drive (approximately 158 acres). This proposed
residential lot will be 7.13 acres in size and be served by North Weld County Water District and an
individual sewage disposal system. Based on the original acreage of the development (204 acres)and re-
evaluating the density for a 6th lot, the overall density is one septic system per 34 acres.
The Department recommends approval with the following conditions:
1. Water service shall be obtained from North Weld County Water District
2. This subdivision is in rural Weld County and is not served by a municipal sanitary sewer
system. Sewage disposal shall be by septic systems 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. A stormwater discharge permit may be required for a development/redevelopment
/construction site where a contiguous or non-contiguous land disturbance is greater than or
equal to one acre in area. Contact the Water Quality Control Division of the Colorado
Department of Public Health and the Environment at www.cdphe.state.co.us/wq/PermitsUnit
for more information.
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 the
Weld County Health Department, a fugitive dust control plan must be submitted.
5. In accordance with the Regulations of the Colorado Air Quality Control Commission any
development that disturbs more than 5 acres of land must incorporate all available and
practical methods that are technologically feasible and economically reasonable in order to
minimize dust emissions.
6. If land development creates more than a 25-acre contiguous disturbance,or exceeds 6 months
in duration, the responsible party shall prepare a fugitive dust control plan, submit an air
pollution emissions notice, and apply for a permit from the Colorado Department of Public
Health and Environment.
7. "Weld County's Right to Farm"as provided in Appendix 22-E of the Weld County Code shall be
placed on any recorded plat.
The following comment was recorded on the Avery Acres Change of Zone plat and is still applicable:
1. Lot owners should be informed that t crop dusting facility is located directly north of this PUD. It is
legally permitted through Use by Special Review Permit#814 and is eligible to apply for expansion.
