USR 19-0004, Amendment to USR 1737
Questionnaire Responses
The purpose for this USR amendment is to include additional uses to the existing USR, and expand the
adjacent AARV Auto & RV Storage, currently located on Lots 6-9 Althen Boyer (USR-16-0026 and SPR 17-
0007).
The proposed additional lot is Parcel 1467-23-000-005, which is located in the E %2 of the W1/2 of the SE
1/4 of Section 23, Township 1N, Range 68W. The physical address is 4343 County Road 6, Erie. This
parcel is directly adjacent to Lots 7-9 Althen Boyer. Applicant is the owner of Lots 6-9 Althen Boyer and
the proposed lot. The property is currently approved as a commercial/agricultural mixed use under USR
1737. The Lot is 10 acres, with approximately 1.5 acres cut off by the Bull Canal. The property is
currently approved for storage of commercial equipment and vehicles, fabrication, auto storage and
repair, and agricultural and horticultural services, animal husbandry, and farm equipment sales, repair,
and installation.
Planning:
The proposed use of the property would add contractor shop as a use in the metal building and specify a
use of screened storage for RVs, boats, trailers, automobiles, containers and equipment. The buildings
will remain as is, except for most of the small barns and corrals, which will be removed. There are no
new structures proposed.
The proposed USR meets the goals and policies of the Weld County Comprehensive Plan under C.Policy
1.1. to ensure that adequate levels of services and facilities are currently available or reasonably
obtainable by the residents in this area of Weld County. There is a great need for larger RV storage
facilities in this area, as most lots are full and people are having a hard time finding places to store their
RVs, boats, trailers, and automobiles.
We believe this property is uniquely located in an area that can support the proposed use, and is
compatible with the region. It fits with the goals of Policy 7.2, which states "Conversion of agricultural
land to nonurban residential, commercial and industrial uses should be accommodated with the subject
site is in an area that can support such development, and should attempt to be compatible with the
region."
This property is bordered on the west by the Althen Boyer Commercial Unit development, which
includes heavy equipment dealers, a salvage yard, equipment rental and RV and trailer sales. The
property to the north and south are vacant, the property to the east is a residential horse property.
Lots 7 and 8 were previously used as a salvage yard by the applicant, and the very organized RV storage
that is happening there now has been a large improvement to the area. The property is bordered on
the east, north and south by Broomfield County.
The property would be available by electronic keypad entry 24 hours a day. New customers are seen by
appointment.
The total number of employees in the building would not exceed 8, as per the original USR. There are
no additional employees needed for the RV Storage use.
Parking spaces at the metal building were outlined on the original USR and are shown on the site map.
There is a space for an ADA parking space if required. No other parking spaces are needed, except for
the RV Storage spaces.
Existing landscaping includes trees and grass. Areas of grass and trees will remain around the buildings.
All other areas will be covered in road base or recycled asphalt. The fenced lot will consist of roadways
of at least 22' and back in and pull through parking rows. The rows are orderly and neatly marked with
ropes. All signage and landscaping will be kept at ground level due to collision risk. The landscaping
maintenance plan consists of mowing, weed spraying, regular ground maintenance of the lots, and trash
pickup.
The proposed use will include the installation of 6' chainlink or other perimeter fencing along the north
and east property lines. The west property line is already fenced to the ditch.
The property is not in the floodplain.
If the special use ever terminates, the ground can be easily reclaimed by removing the rope lines and
road base, and planting grass in the desired areas.
Fire protection is provided by Mountain View Fire District. A meeting has been scheduled with LuAnn
Penfold to discuss their requirements in regards to fire hydrants, etc.
Parking areas will be screened as required from any adjacent landowners and County Road 6.
We are not planning any change to the lighting at this time, other than future motion detection lighting
at the gate. There is already some lighting in place. We may put some lighting by the gate in the future.
All lighting will be shielded and downcast and will in no way impact the neighboring properties.
We would prefer to use the same sign at the County Road 6 auxiliary entrance as we have on the main
entrance. The sign is fence mounted 3' from the ground. The size is 3'x 8'. This sign may not be
installed until this entrance is fitted with an electronic gate.
Any dumpsters will be screened. There is an existing dumpster enclosure on the south side of the
building at the east corner.
We should be able to have the fencing, layout, drainage pond and outlet structure done in 30-90 days
after approval.
Engineering:
We anticipate an average of 15-20 round trips per day to this property. Of this number, most are
passenger cars or trucks, a few might be towing trailers or driveable RVs.
Our customer base is fairly evenly distributed. Property is located in between the Erie and Lafayette
exits and estimates are that that most people will be using the Erie exit which is 1 mile north (due to the
median at Hwy 7 which doesn't allow access to the frontage road unless traveling west). There are also
those from Frederick, coming from the east, as they use Colorado Blvd and Road 6. Anyone coming
from Lafayette would likely take CR 7 to CR 6 and go east under the highway.
Based on the above, estimates are 60% from the north, 10% from the south, 10% from the west, and
20% from the east. Traffic flow is spread through the daylight hours. Less during week, more during the
weekend.
Access will be provided via an easement through Lot 7 by way of the main electric gate of AARV Auto &
RV Storage. An easement will be granted and recorded for this use. An auxiliary access will come off of
County Road 6 at the existing access point. This access will eventually be fitted with an electric gate as
well. This access will have a 60' turning radius as required and be wide enough for 2 way traffic. We
are waiting to hear back from Broomfield County on any requirements that they might have.
The property is within an Urbanizing Drainage Area. The property naturally drains to the NW corner on
the south side of the Bull Canal. A preliminary drainage design has been developed, which will be
designed to detain 27,078 gallons. This will handle runoff rates from the 1 -hour, 100 -year storm from
this parcel. The detention pond is planned on the north side of the ditch, and the water will be directed
to the detention area through a pipe that spans the canal. It will release away from the canal through
an outlet structure at the historic runoff rate of the 1 -hour, 5 -year storm. We are acquiring a drainage
easement for the release waters from the adjacent lot to the west.
We have spoken to the Farmer's Reservoir and Irrigation regarding the future installation of a bridge
across the Bull Canal and they are open to the idea as long as the engineering meets their specifications.
Environmental Health:
Water is provided to this parcel by Central Weld Water District.
The site has 3 septic systems as approved in the USR. There is one at each house and one for the metal
building. No additional people will be needed. We have included information regarding these permits
on the septic information form. Care will be taken to not allow parking or driving over the leach fields.
Storage will include outdoor screened storage of RVs, automobiles, boats, trailers, semi trailers,
equipment, and containers.
There will be no waste oil, fuel storage, or vehicle washing on site. No air emissions are anticipated and
there will be no fugitive dust.

Michael,
Here is the information you requested.
Yes, the 2 existing residences will remain at this time. The tenants are residential. At some time in the future, we may
convert the residence closest to the road to a caretaker/office combination. They are currently occupied by a couple of
women who have horses on the property. These tenants will not be told of our plans until we know things are going
forward.
Our plans for the County Road 6 screening include at least a 6' chain link fence, screened if necessary.
We would like to have a duplicate sign at the expansion lot, but it is not completely necessary to have a sign there. If
we ever make the front house the office, then we would need some signage there.
We would like an option to use the gate on the expansion lot as simply a locked auxiliary entrance for the fire
department. We could also use it in case of malfunction of the main gate. We may eventually put an electric gate
there for the tenants, but for now, there is no reason why everyone cannot access through the main gate and easement
through Lot 7.
We have not talked to Central Weld County Water District, but they should have sufficient supply and pressure for
hydrants. We are waiting to hear from Mountain View Fire about their requirements.
The septic systems are outlined on the water supply info sheet. SP -1100033 serves the commercial building, SP -
9900524 serves the rear house and S-19889009 serves the front house.

Drainage Report checklist
1. Besides the Bull Canal, are there any other nearby water features? Where does the
overall basin drain to?
2. Please provide a drawing showing stormwater basin delineations for on -site and off -site basins. Provide arrows
showing flow patterns on the map.
3. The report mentions that off -site drainage will be routed around the site. Off -site flows can either be routed around
the site or be passed over the ponds emergency overflow spillway un-detained. Please provide a detailed grading
plan showing contours of the proposed swales or berms to route off -site drainage around the site as well as
calculations for the design of these swales and berms.
4. Please show the rainfall depths used in the calculations, either from local maps from the NOAA Atlas website
(https://hdsc.nws.noaa.govlhdsc/pfds/pfds_map_cont.html).
5. Include calculations of the historic (2% impervious) 5 -year, 1 -hour peak flow to show the allowable release rate.
Include Time of Concentration requirements.
6. Please provide imperviousness calculations. All historic basins should be modeled using 2% imperviousness. When
calculating the weighted C value for the proposed site, please model the pond water surface area using a 100%
Impervious value.
7. Include calculations of the developed 100 -year, 1 -hour peak flow. Include Time of Concentration requirements.
When calculating times of concentration, a maximum length of 500 feet should be used for overland flows. Any
length above this should be included in the channelized flows.
8. The submitted grading drawing is not clear on how the eastern half of the site will be conveyed to the pipe that goes
under the Bull Canal. Please provide additional calculations for swales or culverts necessary to transport site flows
to the detention pond or other major drainage area on -site. Swale and culvert calculations should be provided for
off -site flows being routed around the site as required. Permanent erosion control may be required depending on
Froude Number. Swales should be sized to convey the 100 -year developed or historic flow plus freeboard. The
requirement is a foot of freeboard for flows over 50 cfs. For flows under 50 cfs, 1.33 x the design flow may be used.
9. Include calculations for the pond outlet sizing as well as the water quality outlet sizing. The water quality outlet shall
be sized to hold the water quality capture volume for 40 hours to allow particles to settle out of the stormwater prior
to exiting the pond. The 100 -year outlet shall be sized to release the flows from the site at a rate not to exceed the
5 -year historic runoff rate.
10. Please include the design and details for the emergency spillway. Emergency Spillway design standards are in the
Weld County Code Sec 8-11-100.A.6.- "Each detention pond shall contain an emergency spillway capable of
conveying the peak 100 -year storm discharge draining into the detention pond. The invert of the emergency spillway
must be equal to, or above, the 100 -year water surface elevation. The depth of flow out of the emergency spillway
shall be less than 6 inches. The spillway must have effective erosion protection. In order to protect the emergency
spillway from catastrophic erosion failure, buried riprap shall be placed from the emergency spillway downhill to the
embankment toe of slope and covered with 6 inches of topsoil. The riprap must be sized at the time of final engineering
design. Grouting of the riprap may be required." Sec 8-11-100.A.7.- "In order to prevent damage to publicly -owned
Infrastructure (roads, roadside ditches), a concrete cutoff wall 8 inches thick, 3 feet deep, and extending a minimum
of 5 feet into the embankment on each side of the emergency spillway opening, is required on all privately -maintained
detention ponds and required on all regional detention ponds. The concrete cutoff wall permanently defines the
emergency spillway opening. The emergency spillway elevation must be tied back into the top of the embankment
using a maximum slope of 4:1.°

indicates that simplified Full -Spectrum equations were used to size the detention pond.
These equations do not meet the Weld County code as a larger release rate Is assumed.
12. Weld County Code Section 8-11-100.A.5 states "The outlet pipe must contain a minimum
of two
concrete cutoff walls embedded a minimum of 18 inches into undisturbed earthen sod. The cutoff walls must be a
minimum of 8 inches thick. The outlet pipe bedding material must consist of native earthen soil, not granular bedding
material, to at least the first downstream manhole or daylight point." Show these anti -see collars on the construction
drawings.
13. The report indicates that there will be a pipe boring under the Bull Canal. Written permission is required from
FRICO to construct this crossing.
14. The report mentions that the detention pond will control storm water from Lots 6,7,8 and 9 of the Althen-Boyer
Commercial Tract. I believe this is a typo. If it Is intended that this pond will control stormwater from lots within the
Althen-Boyer subdivision, the lot shall be replatted as a part of the subdivision.
15. Please ensure that the submitted drawing is clear enough to read the existing and proposed contour labels. See
notes above for other Construction Drawing requirements.
16. Once the revised design and drainage report have been submitted, the County may provide additional comments in
addition to the ones listed above. Depending on the complexity of the changes made, a full 28 -day review period
may be required.
17. Please provide a written response on how the above comments have been addressed when resubmitting the drainage
report. Thank -you.

USR 19-0004, Amendment to USR 1737
Questionnaire Responses
The purpose for this USR amendment is to include additional uses to the existing USR, and expand the
adjacent AARV Auto & RV Storage, currently located on Lots 6-9 Althen Boyer (USR-16-0026 and SPR 17-
0007).
The proposed additional lot is Parcel 1467-23-000-005, which is located in the E %2 of the W1/2 of the SE
1/4 of Section 23, Township 1N, Range 68W. The physical address is 4343 County Road 6, Erie. This
parcel is directly adjacent to Lots 7-9 Althen Boyer. Applicant is the owner of Lots 6-9 Althen Boyer and
the proposed lot. The property is currently approved as a commercial/agricultural mixed use under USR
1737. The Lot is 10 acres, with approximately 1.5 acres cut off by the Bull Canal. The property is
currently approved for storage of commercial equipment and vehicles, fabrication, auto storage and
repair, and agricultural and horticultural services, animal husbandry, and farm equipment sales, repair,
and installation.
Planning:
The proposed use of the property would add contractor shop as a use in the metal building and specify a
use of screened storage for RVs, boats, trailers, automobiles, containers and equipment. The buildings
will remain as is, except for most of the small barns and corrals, which will be removed. There are no
new structures proposed.
The proposed USR meets the goals and policies of the Weld County Comprehensive Plan under C.Policy
1.1. to ensure that adequate levels of services and facilities are currently available or reasonably
obtainable by the residents in this area of Weld County. There is a great need for larger RV storage
facilities in this area, as most lots are full and people are having a hard time finding places to store their
RVs, boats, trailers, and automobiles.
We believe this property is uniquely located in an area that can support the proposed use, and is
compatible with the region. It fits with the goals of Policy 7.2, which states "Conversion of agricultural
land to nonurban residential, commercial and industrial uses should be accommodated with the subject
site is in an area that can support such development, and should attempt to be compatible with the
region."
This property is bordered on the west by the Althen Boyer Commercial Unit development, which
includes heavy equipment dealers, a salvage yard, equipment rental and RV and trailer sales. The
property to the north and south are vacant, the property to the east is a residential horse property.
Lots 7 and 8 were previously used as a salvage yard by the applicant, and the very organized RV storage
that is happening there now has been a large improvement to the area. The property is bordered on
the east, north and south by Broomfield County.
The property would be available by electronic keypad entry 24 hours a day. New customers are seen by
appointment.
The total number of employees in the building would not exceed 8, as per the original USR. There are
no additional employees needed for the RV Storage use.
Parking spaces at the metal building were outlined on the original USR and are shown on the site map.
There is a space for an ADA parking space if required. No other parking spaces are needed, except for
the RV Storage spaces.
Existing landscaping includes trees and grass. Areas of grass and trees will remain around the buildings.
All other areas will be covered in road base or recycled asphalt. The fenced lot will consist of roadways
of at least 22' and back in and pull through parking rows. The rows are orderly and neatly marked with
ropes. All signage and landscaping will be kept at ground level due to collision risk. The landscaping
maintenance plan consists of mowing, weed spraying, regular ground maintenance of the lots, and trash
pickup.
The proposed use will include the installation of 6' chainlink or other perimeter fencing along the north
and east property lines. The west property line is already fenced to the ditch.
The property is not in the floodplain.
If the special use ever terminates, the ground can be easily reclaimed by removing the rope lines and
road base, and planting grass in the desired areas.
Fire protection is provided by Mountain View Fire District. A meeting has been scheduled with LuAnn
Penfold to discuss their requirements in regards to fire hydrants, etc.
Parking areas will be screened as required from any adjacent landowners and County Road 6.
We are not planning any change to the lighting at this time, other than future motion detection lighting
at the gate. There is already some lighting in place. We may put some lighting by the gate in the future.
All lighting will be shielded and downcast and will in no way impact the neighboring properties.
We would prefer to use the same sign at the County Road 6 auxiliary entrance as we have on the main
entrance. The sign is fence mounted 3' from the ground. The size is 3'x 8'. This sign may not be
installed until this entrance is fitted with an electronic gate.
Any dumpsters will be screened. There is an existing dumpster enclosure on the south side of the
building at the east corner.
We should be able to have the fencing, layout, drainage pond and outlet structure done in 30-90 days
after approval.
Engineering:
We anticipate an average of 15-20 round trips per day to this property. Of this number, most are
passenger cars or trucks, a few might be towing trailers or driveable RVs.
Our customer base is fairly evenly distributed. Property is located in between the Erie and Lafayette
exits and estimates are that that most people will be using the Erie exit which is 1 mile north (due to the
median at Hwy 7 which doesn't allow access to the frontage road unless traveling west). There are also
those from Frederick, coming from the east, as they use Colorado Blvd and Road 6. Anyone coming
from Lafayette would likely take CR 7 to CR 6 and go east under the highway.
Based on the above, estimates are 60% from the north, 10% from the south, 10% from the west, and
20% from the east. Traffic flow is spread through the daylight hours. Less during week, more during the
weekend.
Access will be provided via an easement through Lot 7 by way of the main electric gate of AARV Auto &
RV Storage. An easement will be granted and recorded for this use. An auxiliary access will come off of
County Road 6 at the existing access point. This access will eventually be fitted with an electric gate as
well. This access will have a 60' turning radius as required and be wide enough for 2 way traffic. We
are waiting to hear back from Broomfield County on any requirements that they might have.
The property is within an Urbanizing Drainage Area. The property naturally drains to the NW corner on
the south side of the Bull Canal. A preliminary drainage design has been developed, which will be
designed to detain 27,078 gallons. This will handle runoff rates from the 1 -hour, 100 -year storm from
this parcel. The detention pond is planned on the north side of the ditch, and the water will be directed
to the detention area through a pipe that spans the canal. It will release away from the canal through
an outlet structure at the historic runoff rate of the 1 -hour, 5 -year storm. We are acquiring a drainage
easement for the release waters from the adjacent lot to the west.
We have spoken to the Farmer's Reservoir and Irrigation regarding the future installation of a bridge
across the Bull Canal and they are open to the idea as long as the engineering meets their specifications.
Environmental Health:
Water is provided to this parcel by Central Weld Water District.
The site has 3 septic systems as approved in the USR. There is one at each house and one for the metal
building. No additional people will be needed. We have included information regarding these permits
on the septic information form. Care will be taken to not allow parking or driving over the leach fields.
Storage will include outdoor screened storage of RVs, automobiles, boats, trailers, semi trailers,
equipment, and containers.
There will be no waste oil, fuel storage, or vehicle washing on site. No air emissions are anticipated and
there will be no fugitive dust.

Michael,
Here is the information you requested.
Yes, the 2 existing residences will remain at this time. The tenants are residential. At some time in the future, we may
convert the residence closest to the road to a caretaker/office combination. They are currently occupied by a couple of
women who have horses on the property. These tenants will not be told of our plans until we know things are going
forward.
Our plans for the County Road 6 screening include at least a 6' chain link fence, screened if necessary.
We would like to have a duplicate sign at the expansion lot, but it is not completely necessary to have a sign there. If
we ever make the front house the office, then we would need some signage there.
We would like an option to use the gate on the expansion lot as simply a locked auxiliary entrance for the fire
department. We could also use it in case of malfunction of the main gate. We may eventually put an electric gate
there for the tenants, but for now, there is no reason why everyone cannot access through the main gate and easement
through Lot 7.
We have not talked to Central Weld County Water District, but they should have sufficient supply and pressure for
hydrants. We are waiting to hear from Mountain View Fire about their requirements.
The septic systems are outlined on the water supply info sheet. SP -1100033 serves the commercial building, SP -
9900524 serves the rear house and S-19889009 serves the front house.

AARV STORAGE REPRESENTED BY JUDY HEFNER.
I. GENERAL LOCATION AND LOCATION DESCRIPTION
THE AARV STORAGE IS LOCATED ON THE NORTH SIDE OF WELD COUNTY
ROAD 6, AND ON THE EAST SIDE OF LOTS 6, 7, 8, AND 9 ALTHEN-BOYER
COMMERCIAL TRACT, DIVIDED ON THE NORTH BY THE BULL CANAL, AND ON THE
EAST BY AGRICULTURAL LAND.
A DETENTION POND THAT HOLDS THE 1 HOUR 100 YEAR STORM IS TO BE
CONSTRUCTED WITH OUTLETS THAT ALLOW THE 5 YEAR HISTORICAL FLOWS TO
BE RELEASED.
II. DESCRIPTION OF THE PROPERTY
THE SUBJECT PROPERTY CONSISTS OF 10.006 ACRES OF LAND. THE BULL
CANAL HAS A 50 FT. WIDE RIGHT OF WAY THROUGH THE NORTHERN PART OF
THE SITE. THERE ARE TWO RESIDENCES AND OTHER AREAS THAT WILL NOT BE
DEVELOPED.
A. THE DRAINAGE AREA IS 10.OO6 ACRES OF LAND WITH AN AREA OF 0.20
ACRES OF THE BULL CANAL THAT DOESN'T CONTRIBUTE TO THE RUN
OFF FROM THE CITE.
B. THE FLOWS FROM THE SOUTHERN PART OF THE SITE WILL BE PIPED
ACROSS THE BULL CANAL TO A DETENTION POND NOTH OF THE DITCH.
C. A BRIDGE WILL BE CONSTRUCTED NEAR THE EASTERN BOUNDARY OF
THE PROPERTY TO PROVIDE TO PROVIDE A ROAD TO MAINTAIN THE
DETENTION POND.
D. ALL OFFSITE FLOWS ARE DIRECTED AROUND THE DRAINAGE AREA WITH
ONLY THE DESIGNATED AREAS ZAUSING THE DETENTION STRUCTURE.
III. DRAINAGE DESIGN CRITERIA REGULATIONS
THE PROPOSED DRAINAGE DESIGN COMPLIES WITH THE UDFCD CRITERIA
MANUAL AND THE WELD COUNTY CODE.
DEVELOPMENT CRITERIA REFERENCE AND CONSTRAINTS BASED ON
EXISTING GRADE ELEVATIONS AT THE PERIMETER OF THE SUBJECT PROPERTY,
RUNOFF GENERATED BY THIS PROJECT, UNDER BOTH HISTORIC AND PROPOSED
CONDITIONS, MAY ENTER THE DETENTION FACILITIES PLANNED BY THESE
DEVELOPMENTS.
HYDROLOGICAL CRITERIA -
THE EMPIRICAL EQUATIONS WERE USED FOR SIZING OF THE ON SITE
DETENTION IN ESTIMATING THE 100 YEAR RECURRENT STORM PEAK RATES OF
RUNOFF FOR THE MAJOR STORM EVENT.
DRAINAGE FACILITY DESIGN CONCEPT -
THE PROPOSED STORM WATER DESIGN WILL MAINTAIN THE HISTORIC
DRAINAGE DISCHARGE FROM THE SITE.
THE STORM WATER RUNOFF FROM THE SITE WILL BE COLLECTED IN THE
DETENTION POND AND BE RELEASED AT THE HISTORIC RATE. THE OFFSITE STORM
FLOWS WILL BE DIRECTED AROUND THE DETENTION POND, WITH THE POND
ONLY CONTROLING THE STORM WATER FROM THE LOTS 6, 7, 8, AND 9 OF THE
ALTHEN- BOYER COMMERCIAL TRACT.
THE STORM WATER WILL FLOW BY SHEET FLOW TO THE DETENTION POND.
MAINTANCE PLAN WILL BE TO CLEAN TRASH RACKS WEEKLY OR AS REQUIRED TO
MAINTAIN FLOWS AND REMOVE SILT THAT REDUCES THE VOLUME OF THE
STORAGE POND. THE VEGETATION IN THE POND WILL BE MOWED AND
DISPOSED OFF AS NEEDED.

Drainage Report checklist
1. Besides the Bull Canal, are there any other nearby water features? Where does the
overall basin drain to?
2. Please provide a drawing showing stormwater basin delineations for on -site and off -site basins. Provide arrows
showing flow patterns on the map.
3. The report mentions that off -site drainage will be routed around the site. Off -site flows can either be routed around
the site or be passed over the ponds emergency overflow spillway un-detained. Please provide a detailed grading
plan showing contours of the proposed swales or berms to route off -site drainage around the site as well as
calculations for the design of these swales and berms.
4. Please show the rainfall depths used in the calculations, either from local maps from the NOAA Atlas website
(https://hdsc.nws.noaa.govlhdsc/pfds/pfds_map_cont.html).
5. Include calculations of the historic (2% impervious) 5 -year, 1 -hour peak flow to show the allowable release rate.
Include Time of Concentration requirements.
6. Please provide imperviousness calculations. All historic basins should be modeled using 2% imperviousness. When
calculating the weighted C value for the proposed site, please model the pond water surface area using a 100%
Impervious value.
7. Include calculations of the developed 100 -year, 1 -hour peak flow. Include Time of Concentration requirements.
When calculating times of concentration, a maximum length of 500 feet should be used for overland flows. Any
length above this should be included in the channelized flows.
8. The submitted grading drawing is not clear on how the eastern half of the site will be conveyed to the pipe that goes
under the Bull Canal. Please provide additional calculations for swales or culverts necessary to transport site flows
to the detention pond or other major drainage area on -site. Swale and culvert calculations should be provided for
off -site flows being routed around the site as required. Permanent erosion control may be required depending on
Froude Number. Swales should be sized to convey the 100 -year developed or historic flow plus freeboard. The
requirement is a foot of freeboard for flows over 50 cfs. For flows under 50 cfs, 1.33 x the design flow may be used.
9. Include calculations for the pond outlet sizing as well as the water quality outlet sizing. The water quality outlet shall
be sized to hold the water quality capture volume for 40 hours to allow particles to settle out of the stormwater prior
to exiting the pond. The 100 -year outlet shall be sized to release the flows from the site at a rate not to exceed the
5 -year historic runoff rate.
10. Please include the design and details for the emergency spillway. Emergency Spillway design standards are in the
Weld County Code Sec 8-11-100.A.6.- "Each detention pond shall contain an emergency spillway capable of
conveying the peak 100 -year storm discharge draining into the detention pond. The invert of the emergency spillway
must be equal to, or above, the 100 -year water surface elevation. The depth of flow out of the emergency spillway
shall be less than 6 inches. The spillway must have effective erosion protection. In order to protect the emergency
spillway from catastrophic erosion failure, buried riprap shall be placed from the emergency spillway downhill to the
embankment toe of slope and covered with 6 inches of topsoil. The riprap must be sized at the time of final engineering
design. Grouting of the riprap may be required." Sec 8-11-100.A.7.- "In order to prevent damage to publicly -owned
Infrastructure (roads, roadside ditches), a concrete cutoff wall 8 inches thick, 3 feet deep, and extending a minimum
of 5 feet into the embankment on each side of the emergency spillway opening, is required on all privately -maintained
detention ponds and required on all regional detention ponds. The concrete cutoff wall permanently defines the
emergency spillway opening. The emergency spillway elevation must be tied back into the top of the embankment
using a maximum slope of 4:1.°

indicates that simplified Full -Spectrum equations were used to size the detention pond.
These equations do not meet the Weld County code as a larger release rate Is assumed.
12. Weld County Code Section 8-11-100.A.5 states "The outlet pipe must contain a minimum
of two
concrete cutoff walls embedded a minimum of 18 inches into undisturbed earthen sod. The cutoff walls must be a
minimum of 8 inches thick. The outlet pipe bedding material must consist of native earthen soil, not granular bedding
material, to at least the first downstream manhole or daylight point." Show these anti -see collars on the construction
drawings.
13. The report indicates that there will be a pipe boring under the Bull Canal. Written permission is required from
FRICO to construct this crossing.
14. The report mentions that the detention pond will control storm water from Lots 6,7,8 and 9 of the Althen-Boyer
Commercial Tract. I believe this is a typo. If it Is intended that this pond will control stormwater from lots within the
Althen-Boyer subdivision, the lot shall be replatted as a part of the subdivision.
15. Please ensure that the submitted drawing is clear enough to read the existing and proposed contour labels. See
notes above for other Construction Drawing requirements.
16. Once the revised design and drainage report have been submitted, the County may provide additional comments in
addition to the ones listed above. Depending on the complexity of the changes made, a full 28 -day review period
may be required.
17. Please provide a written response on how the above comments have been addressed when resubmitting the drainage
report. Thank -you.
