SUBJECT: RES14-0001, Lake Arrowhead Water Association
The Weld County Public Works Department has reviewed this proposal. Staff comments made during this
phase of the process may not be all-inclusive, as other concerns or issues may arise during the remaining
application process. Issues of concern must be resolved with the Public Works Department. Our
comments and requirements are as follows:
COMMENTS:
This property is defined as parcel number 095927107005 and is located southwest of 47th ave and 37st
street in the Greeley area. The change of zone (COZ14-0005) and re-subdivision (RES14-0001) are
related.
This site is in a State defined Municipal Separate Storm Sewer System (MS4) area which is a more
urbanized area with state mandated, higher water quality requirements.
This site lies within a FEMA regulatory floodplain. All construction or improvements occurring in a FEMA
regulatory floodplain delineated by FEMA Shall comply with Overlay District requirements of Chapter 23,
Article V, Division 2 of the Weld County Code. A Floodplain Development Permit is required for
development in the floodplain.
An access permit has been approved for accesses onto Kiowa drive and Pawnee drive, AP14-000300.
CONDITIONS OF APPROVAL:
The plat shall be amended to delineate the following:
Kiowa Drive and Pawnee Drive are designated on the Weld County Road Classification Plan as paved
local roads which require 60ft of right-of-way at full build out. These roadways are within the Arrowhead
4`"filing subdivision. The applicant shall verify the existing right-of-way and the documents creating the
right-of-way and this information shall be noted on the plat. All setbacks shall be measured from the edge
of future right-of-way. These roads are maintained by Weld County.
Show the approved access(es) on the plat and label with the approved access permit number AP14-
00300.
Show and label the floodplain and floodway (if applicable) boundaries on the plat. Label the floodplain
boundaries with the FEMA Flood Zone and FEMA Map Panel Number.
DEVELOPMENT STANDARDS
1. Should noxious weeds exist on the property, or become established as a result of the proposed
development, the applicant/landowner shall be responsible for controlling the noxious weeds,
pursuant to Chapter 15, Articles I and II, of the Weld County Code.
2. The historical flow patterns and runoff amounts will be maintained on the site.
3. This site is located in a State Designated, Municipal Separate Storm Sewer System (MS4) Area
which may trigger specific water quality requirements or other drainage improvements if the lot
develops further.
4. All construction or improvements occurring in the floodplain or floodway as delineated on Federal
Emergency Management Agency (FEMA) FIRM Community Panel Map #080266-0619C dated
September 28, 1982 shall comply with all applicable Weld County requirements, Colorado Water
Conservation Board requirements as described in Rules and Regulations for Regulatory Floodplains
in Colorado and FEMA regulations and requirements as described in 44 CFR parts 59, 60, and 65.
5. Floodplain development permits will be required for development activities located within the special
flood hazard area. The FEMA definition of development is any man-made change to improved or
unimproved real estate, including by not limited to buildings or other structures, mining, dredging,
filling, grading, paving, excavation, drilling operations, or storage of equipment and materials.
6. FEMA's floodplain boundaries may be updated at any time by FEMA. Prior to the start of any
development activities, the owner should contact Weld County to determine if the floodplain
boundaries have been modified.

CASE NO.: RES14-0001 NAME: Lake
Arrowhead Water Association
Environmental Health Services has reviewed this proposal to divide Tract A of
Arrowhead Subdivision 4th Filing into two lots. This case is being processed in
conjunction with Change of Zone COZ14-0005.
Two 5 acre parcels will be created which will be served by the City of Evans for water
and individual on-site wastewater treatment systems for sewer (OWTS). A water tap
agreement for one tap, dated May 8, 1996, was included in the application. Both
proposed lots are encumbered by floodplain. On-site wastewater treatment systems
cannot be located in the floodway.
A geotechnical report was prepared for the site by CDS Engineering Corporation on
June 3, 2014. The preliminary percolation data indicates the site will be unsuitable for
conventional septic systems. Two percolation tests were conducted at each site
however the map submitted was not legible. The percolation results were 100 minutes
per inch or higher which requires engineered designed septic systems. There is also
shallow bedrock at the site. In addition a setback of 50 feet from the lake is required
depending on the type of septic system that will be designed. This Department is
requiring septic system envelopes on the lots due to setbacks, floodplain and
inadequate soils located on each site.
This Department recommends that language for the preservation and/or protection of
the absorption field envelope shall be placed in the development covenants as well as a
note on the change of zone and the resubdivision plat in accordance with Section 30-8-
90 of the Weld County On-site Wastewater Treatment Systems Regulations. The note
should state "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."
The Department recommends that the following conditions be part of any approval:
1. Prior to recording the plat:
A. Delineate a septic envelope on each lot that is not located in the floodway and
adheres to the required setback from the lake.
B. Provide a water tap agreement or certificate of proof of payment of fees for
each parcel.
The following should appear as notes on the resubdivision plat:
1. Water service shall be obtained from the City of Evans.
2. This parcel 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. Language for the preservation and/or protection of the absorption field shall
be placed on the plat. The note shall state; 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 the Weld County Health Department, a fugitive
dust control plan must be submitted.
5. If land development 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.
6. Weld County's "Right to Farm" as provided in Appendix 22-E of the Weld County
Code shall be placed on any recorded plat.
7. 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.

General Comments
E Per the Preliminary DFIRM maps provided by the Colorado Water Conservation Board,
the original lot appears to be in the flood plain and flood zones mapped. The new lots will
be affected by flood plain development regulations and will need to follow all applicable
guidelines with regards to flood control and flood mitigation. Please contact Weld
County Flood Plain Manager for further information.
