SITE SPECIFIC DEVELOPMENT PLAN AND AMENDED USE BY SPECIAL
REVIEW(USR) QUESTIONNAIRE
1. Explain, in detail, the proposed use of the property. The proposed user of the
property provides vehicle suppliers (primarily insurance companies) with a full range of
services to process and sell intact insurance damaged vehicles, primarily to licensed
dismantlers, rebuilders and used vehicle dealers. Intact insurance damaged vehicles are
either damaged vehicles deemed a total loss for insurance or business purposes or are
recovered stolen vehicles for which an insurance settlement with the vehicle owner has
already been made.
Following an accident involving an insured vehicle, a damaged vehicle is towed
to a towing company or a vehicle repair facility for temporary storage pending insurance
company examination. The vehicle is inspected by the insurance company's adjuster,
who estimates the cost of repairing the vehicle and gathers information regarding the
damaged vehicle's mileage options and condition in order to estimate the pre-loss value
(ACV). The insurance company's adjuster determines whether to pay for the repairs or
to classify the vehicle as a total loss, based upon the adjuster's estimate of repair costs
and the vehicle's salvage value, as well as customer service considerations. If the cost of
repair is greater than the ACV less the estimated salvage value, the insurance company
generally will classify the vehicle as a total loss. The insurance company will thereafter
assign the vehicle to a salvage vehicle auction company, settle with the insured vehicle
owner, and receive title to the vehicle.
Upon receipt of a pick-up order, which is conveyed by telephone, facsimile or via
the Internet, the proposed user dispatches a towing company to transport the vehicle to
the proposed user's facility. After being received and inventoried at the facility, the
vehicle remains in storage until receipt of ownership documents from the insurance
company. The vehicle is thereafter placed for sale on user's VB2 auction-style Internet
website, which allows vehicle buyers to preview the vehicles for the 3 days prior to the
virtual sale and place preliminary bids at the facility or from anywhere on a computer
with Internet access. In the final stage of the VBZ powered sale, the high preliminary bid
is carried over to the virtual sale, where potential buyers must bid at a remote computer
with Internet connection. All vehicles are sold to the highest Internet bidder. Sold
vehicles are transported from the facility by the successful bidders.
Typically the user's facility will consist of an office building, customer parking,
vehicle receiving area, and gravel storage yard for vehicles. No vehicle dismantling,
crushing, or sale of parts occurs at user's facility. Vehicles are stored in an orderly
manner and are never stacked. Vehicles remain in storage for an average of 60-70 days.
2. Explain how this proposal is consistent with the intent of the Weld County Code,
Chapter 22 (Comprehensive Plan). This proposal is consistent with the intent of the
Comprehensive Plan because there are other areas of industrial zoning in the immediate
vicinity of this property and it is adjacent to Highway 85, which supports other industrial
uses. The proposed use is not a high intensity use in terms of the hours of operation;
numbers of employees, as compared to other industrial uses which might adversely
impact the immediate area or contribute to a greater need for utilization of services
provided by Weld County.
3. Explain how this proposal is consistent with the intent of the Weld County Code,
Chapter 23 (Zoning) and the zone district in which it is located. The use being requested
is consistent with the zoning code because other properties adjacent to this property have
been zoned for industrial use. Industrial areas need strong transportation networks.
Highway 85 and the existing adjacent transportation railway system are capable of
supporting further industrial use.
4. What types of uses surround the site? Explain how the proposed use is consistent
and compatible with surrounding land uses. The property to the west of the proposed
land use is a lake, which is used for water skiing purposes. The common boundary of the
two parcels will be fenced to minimize any visual impact, which might occur to the west.
Applicant has constructed a storm drainage detention facility to minimize the impact of
storm water traveling from the applicant's property to the lake so discharges will occur in
a manner consistent with the historic runoff of the two properties. The property to the
north is used for industrial purposes. The property adjoining on the east involves one
residential use and other industrial uses. Each of the common boundaries with other
properties will be fenced to minimize any visual impact, which may occur from the
development of the site for its proposed use. Each of the uses surrounding the site is a
low intensity use, which does not create the potential for an adverse impact by the use
being requested. The screening and fencing utilized by the applicant will insure there is
no adverse impact to any neighboring property. Weld County Road 27 separates the site
from properties to the east, as does the railroad line for the Union Pacific Railroad. The
proposed fencing to be used by the applicant will minimize any adverse impact to the
adjoining property to the east. No vehicles stored on the applicant's property should be
seen by any traffic traveling along Weld County Road 27.
5. Describe, in detail, the following:
a. How many people will use this site? The proposed use is NOT open to the
general public. It is anticipated between 20 and 30 people would visit the site
on a daily basis.
b. How many employees are proposed to be employed at this site? There will be
between 10 and 20 employees. Half of the employees will be in the office
area and half of the employees will be outside in the storage yard.
c. What are the hours of operation? 7:00 A.M. to 6:00 P.M. Monday through
Friday with no weekend operation.
d. What type and how many structures will be erected (built) on this site? The
user will not construct any new structures on site. The user will utilize a
9,600 square foot office/warehouse and a 7,200 square foot warehouse.
e. What type and how many animals, if any, will be on this site? None.
2
f. What kind (type, size, weight) of vehicles will access this site and how often?
The site will be limited to the storage of vehicles assigned to the user of the
property by insurance companies. Those vehicles have included: cars, trucks,
sport utility vehicles, vans,recreational vehicles, buses, Semi's tractor-trailers,
trailers, motorcycles, all terrain vehicles, scooters, mopeds, boats, jet/skis,
small tractors, backhoes, and heavy equipment. The applicant has created a
four (4) acre non-standard vehicle storage area onsite to store larger vehicles
in an area where they will not be seen by traffic on Weld County Road 27,
Weld County Road 4, Weld County Road 6, or Highway 85. The non-
standard vehicles stored on the site make up less than 1% of the vehicles
stored. The vast majority of vehicles stored are cars, trucks, and sport utility
vehicles. Vehicles which will deliver the above described damaged vehicles
to the site will most commonly be tow trucks which account for 98% of the
delivery vehicles and the remaining 2% will be delivered by semi tractor-
trailer combinations. Vehicles will be transported from the site in the same
manner.
g. Who will provide fire protection to the site? The Brighton Fire Protection
District will respond to requests for emergency services.
h. What is the water source on the property? (Both domestic and irrigation).
Domestic water services will be met by the use of a well, which has been on
site for many years and is sufficient to provide for domestic needs.
i. What is the sewage disposal system on the property? (Existing and proposed).
A new septic tank and leach field have been built east of the warehouse and
north of the office building located on the site and have been sized to
accommodate the number of employees identified in paragraph a above.
j. If storage or warehousing is proposed, what type of items will be stored? All
storage of vehicles will be outdoors. Sufficient access lanes will be included
in the storage area to allow for emergency vehicles to enter the property and
move around the property. The site will include an office building, customer
parking, and vehicle receiving area and the user will have 3 to 4 forklifts on
site, which will be stored in a warehouse building. No vehicle dismantling,
crushing or sale of parts will occur on the site. Vehicles will be stored in an
orderly manner and are never stacked. Generally, vehicles remain in storage
for an average of 60 to 70 days.
6. Explain the proposed landscaping for the site. No exterior landscaping is
proposed for the site. The proposed user would construct an eight (8) foot solid
steel fence around the exterior boundary of the property. The color of the fence
will be white.
7. Explain any proposed reclamation procedures when termination of the Use by
Special Review activity occurs. No reclamation procedures will be required.
8. Explain how the storm water drainage will be handled on this site. The property
is relatively flat, however it drains in a northwesterly direction. In the original
application approved by Weld County, a storm detention pond was placed in the
3
northwest corner of the property. All storm water will be directed to the drainage
facility. A berm has been built on the existing property and will be built on the
additional property to influence all storm water to the drainage facility. The user
will add six (6) inches of crushed asphalt over the soil and some absorption of
rain and snow will occur through the asphalt and then to the soil beneath the
asphalt. The storm drainage detention facility has been designed to accept water
for a 100 year storm event and discharge the water in accordance with storm
drainage requirements established by Weld County. It is the applicants belief the
storm drainage discharge will not increase the historic runoff which has occurred
from the northwest corner of the property. All storm drainage will be directed
into the lake of the adjacent property owner which is in accordance with the
historic drainage practice of this site. The storm drainage facility has also been
constructed to avoid any storm water quality discharge issues.
9. Explain how long it will take to construct this site and when construction and
landscaping is scheduled to begin. Approximately 45 acres of the application has
already been constructed. The perimeter fencing has been installed, the office and
warehouse have been modified to allow the use to begin and the storm drainage
facility has been constructed. If the amendment is approved, the applicant
anticipates it will take approximately 90 days to grade the area of the site, build
the berm, build the fencing, and add the crushed asphalt to the property south of
the existing use by special review. The applicant has placed a snow fence on the
western and southern boundaries of the northeast parcel identified as Parcel 4
which separates the 2.67 acres of the parcel from the original use by special
review which was approved. Upon approval of the amendment, the 2.67 acre
parcel will be ready to use immediately because improvements were made as the
original parcel was completed.
10. Explain where storage and/or stockpile of wastes will occur on this site. All waste
storage will occur in waste containers, which will be fenced internally. Those
containers will be emptied on a systematic basis to avoid overflow of materials to
be placed in those containers. Those containers will not be used for the storage of
any materials associated with the vehicles on site.
