C.2 Narrative Site Description
Part I.B.1. Contents and Requirements - Site Description
a) Description of Construction Activities
Lot 23 Claremont Business Park Filing No. 2 (herein referred to as the
Site) consists of 0.39 acres within a portion of the northeast quarter of Section 8,
Township 14 South, Range 66 West of the Sixth P.M. in El Paso County,
Colorado. This site is bounded by undeveloped lots to the north, east and west,
and Cole View to the south. Proposed development of the site consists of a
warehouse with associated paving and landscaping. The site ultimately drains
into Sand Creek via existing storm drain systems.
The site is currently undeveloped and covered with native grasses. The
terrain is fairly flat and generally drains from northeast to southwest. Existing
soils on the site consist mostly of Ellicott loamy coarse sand (Map Symbol 28).
The average existing soil condition on the site reflects the characteristics of
Hydrologic Soil Group ‘A’ as designated in the “Soil Survey of El Paso County
Area,” prepared by the USDA NRCS. The site ultimately drains into Sand Creek.

C.3 Site Map
Part I.C.2 Stormwater Management Plan (SWMP – Contents: Site Map)
See the approved Overlot Grading & Erosion Control Plans for this site.
These plans are considered part of this SWMP and shall be kept at the site at
all times. Modifications to the erosion control plan may be necessary from
time to time based on site inspections. Any additions or deletions of erosion
control measures should be documented on the site copy of the Overlot
Grading & Erosion Control Plans.
C.4 BMP’s and Other Controls
Part I.B.3 Contents and Requirements – BMP’s for Stormwater Pollution Prevention
a) Erosion and Sediment Controls
1) Structural Practices for Erosion and Sediment Control
Use of filter fabric silt fencing at site perimeter locations and
throughout the site (before commencement of construction activities).
Silt fence shall also be located around dirt stockpiles.
Straw bale barriers to protect ditches, swales and inlets (immediately
after construction of each item).
Vehicle tracking control devices at construction traffic ingress/egress
points to prevent sediment tracking onto surrounding streets (before
commencement of construction activities).
Slope protection erosion control blankets shall be installed and staked
on 3:1 slopes as shown on the Overlot Grading & Erosion Control Plan
or as deemed appropriate by the site construction manager (installed
after completion of overlot grading operations).
All disturbed areas shall have crimped straw installed and shall be
reseeded. A recommended seed mix and application rate is included
below.
All slopes not covered with slope protection erosion control blankets
shall be roughed. Roughening shall be performed to follow the
contour of the slope, that is, the roughening shall be perpendicular to
surface runoff flow direction.
Page 7 of 13
There is 1 permanent regional detention pond facility adjacent to the
project that includes water quality capture volume. The water quality
volume portion of the permanent pond shall not serve as temporary
sedimentation basins during and after site construction. The contractor
should be aware that the sedimentation basins are considered a last line
of defense and that the majority of sediment should be contained on
the site near the source of the erosion using the other structural
sediment control measures described in this report.
2) Non-structural Practices for Erosion and Sediment Control
Temporary or permanent seeding will be employed in all areas
disturbed by construction activities that will remain dormant for
greater than 60 days. Should excessive blowing of sediment become
apparent, then the contractor shall water the site for dust control.
Recommended Seed Mix:
Sandy Foothills
Drilled 30 lbs/ acre, Broadcast 35 lbs/ acre
15% Prairie Sandreed
25% Sideoats Grama
15% Blue Grama
20% Switch Grass
25% Little Bluestem
3) Materials Handling and Spill Prevention
Spill prevention and containment measures shall be used at storage,
and equipment fueling and servicing areas to prevent the pollution of
any state waters, including wetlands. All spills shall be cleaned up
immediately after discovery, or contained until appropriate cleanup
methods can be employed. Manufacturer’s recommended methods for
spill cleanup shall be followed, along with proper disposal methods.
The contractor shall follow the recommendations of the appropriate
Hazard Communication Plan of the site construction manager, general
contractor, or site superintendent.
Some spills may need to be reported to the Government immediately.
Specifically, a release of any chemical, oil, petroleum product, sewage,
etc., which may enter waters of the U.S. (which include surface water,
ground water, and dry gullies or storm sewers leading to surface water)
must be reported.

Part I.B.5. Contents and Requirements – Other Controls
Identification of Potential Pollutant Sources
All disturbed and stored soils
Topsoil shall be stockpiled and surrounded by silt fence as shown
on the Grading and Erosion Control Plan in the Appendix of this
report.
Vehicle tracking of sediments
Construction vehicles will be exiting the site from unpaved
surfaces and onto paved surfaces, which presents a significant
possibility for sediment transport.
Management of contaminated soils
There are no known contaminated soils on this site.
Loading and unloading operations
Construction materials loading and unloading activities will exist
on-site. Materials should be neatly placed in appropriate staging
areas. Any materials that are subject to displacement from
blowing wind should be adequately sheltered from the wind.
Outdoor storage activities (building materials, fertilizers, chemicals, etc.)
The quantity of materials stored on the project site shall be limited,
as much as practical, to that quantity required to perform the work
in an orderly sequence. All materials stored on-site shall be stored
in a neat, orderly manner, in their original containers, with original
manufacturer’s labels. Materials shall not be stored in a location
where they may be carried by stormwater runoff into a State Water
at any time.
Vehicle and equipment maintenance and fueling
Vehicle Fueling – there is no known vehicle fueling station to be
installed or used on this site. However, it is anticipated that
construction equipment may be refueled during construction. Spill
prevention and containment measures shall be used at equipment
fueling and servicing areas to prevent the pollution of any state
waters, including wetlands. All spills shall be cleaned up
immediately after discovery, or contained until appropriate cleanup
methods can be employed. Manufacturer’s recommended methods
for spill cleanup shall be followed, along with proper disposal
Page 9 of 13
methods. The contractor shall follow the recommendations of the
appropriate Hazard Communication Plan of the site construction
manager, general contractor, or site superintendent. Vehicle
refueling should be done in an area surrounded by an earthen berm
to contain any fuel spills. Containment berming should be of
sufficient size to safely contain a spill from the largest tank truck
or other containment device located inside the possible spill area.
In the event of a spill, a method of removal must be provided, such
as application of sorbent materials and the use of a pump or
vacuum truck. Any material removed from the spill site must be
disposed of according to local, state, and federal standards.
Stormwater and snowmelt runoff shall be diverted away from the
containment berming area. Water that collects within the berming
due to rainfall or snowmelt must be treated to meet standards
before release from the spill area.
Vehicle Maintenance – from time to time it may be necessary for
the contractor to perform maintenance on the construction
equipment being used on the site. If possible, major repairs to
construction equipment shall be done off-site. Basic vehicle
maintenance shall be performed in the vehicle fueling area and all
recommendations listed above shall be followed.
Significant dust or particulate generating processes
Should excessive blowing of sediment become apparent, then the
contractor shall water the site for dust control.
Routine maintenance activities involving fertilizers, pesticides, detergents,
fuels, solvents, oils, etc.
The application of fertilizers and pesticides (if used) should be
done using the method and rates recommended by the
manufacturer. These applications shall not cause runoff or
potential damage to receiving bodies of water. Vehicle fuels and
maintenance are described above.
On-site waste management practices (waste piles, liquid wastes,
dumpsters, etc.)
Contractors shall take steps to keep the site reasonably free from
large amounts of construction debris during construction. All
waste materials generated by construction activities shall be
removed from the site. All wastes composed of building materials
must be removed from the construction site for disposal in
accordance with local and state regulatory requirements. No
building material wastes or unused building materials shall be
buried, dumped, or discharged at the site. Any waste materials
stored in dumpsters shall be adequately covered to prevent blowing
debris.
All wastes composed of building materials must be removed from
the construction site for disposal in accordance with local and State
regulatory requirements. No building material wastes or unused
Page 10 of 13
building materials shall be buried, dumped, or discharged at the
site.
Concrete truck/equipment washing, including the concrete truck chute
and associated fixtures and equipment.
Concrete wash water shall not be discharged to or allowed to
runoff to Waters of U.S., including any surface or subsurface storm
drainage system or facilities. Any concrete wash water shall be
done in a temporary pit on site. The area around this pit shall be
protected with silt fence and the concrete inside the pit shall be
removed when done.
Non-industrial waste sources such as worker trash and portable toilets
Portable toilets located on the site shall be staked in place using t-
posts to prevent them from tipping over during high winds.
Other areas or procedures where potential spills can occur
Spill prevention and containment measures shall be used at
storage, and equipment fueling and servicing areas to prevent the
pollution of any State Waters, including wetlands. All spills shall
be cleaned up immediately after discovery, or contained until
appropriate cleanup methods can be employed. Manufacturer’s
recommended methods for spill cleanup shall be followed, along
with proper disposal methods.
Some spills may need to be reported to the Government
immediately. Specifically, a release of any chemical, oil,
petroleum product, sewage, etc., which may enter waters of the
U.S. (which include surface water, ground water, and dry gullies or
storm sewers leading to surface water) must be reported.
C.5 Final Stabilization and Long-term Stormwater Management
Part I.B.4. Contents and Requirements – Final Stabilization and Long-term
Stormwater Management
Permanent sediment control measures include building construction, paving
of the drive aisles and parking lot, installation of riprap, and the installation of
landscaping and reseeding with a native grass seed mix. The contractor shall consult
the approved Landscape Plan for the proper location, species, and installation
methods for landscaping on the site. If the owner reasonably maintains the
landscaping and reseeding, then it will provide good soil stability and sediment
control. After these permanent measures are installed and final stabilization is
achieved, then temporary measures can be removed. Final stabilization is considered
achieved when all earth disturbing activities at the site have been completed and
uniform vegetative cover has been established with a density of at least 70% of pre-
disturbance levels and such cover is capable of adequately controlling soil erosion.
Soil erosion control measures for all slopes, channels, ditches, or any
disturbed land area shall be completed within twenty-one (21) calendar days after
final grading, or final earth disturbance, has been completed. Disturbed areas and
stockpiles which are not at final grade but will remain dormant for longer than 30
days shall also be mulched within 21 days after interim grading. An area that is going
Page 11 of 13
to remain in an interim state for more than 60 days shall also be seeded. All
temporary soil erosion control measures and BMP’s shall be maintained until
permanent soil erosion control measures are implemented.
All earth disturbances shall be designed, constructed, and completed in such
a manner so that the exposed area of any disturbed land shall be limited to the shortest
practical period of time.
C.6 Inspection and Maintenance Procedures
Part I.B.6. Contents and Requirements – Inspection and Maintanence
The site construction manager or site inspector responsible for these
measures shall inspect them periodically and after every storm event. This report
recommends that all erosion control measures on the site are inspected a minimum of
once every 7 days OR every 14 days and within 24 hours of a significant rainfall
event except during winter snow pack conditions where no melting is occurring or
when all construction activities are completed.
Based on the results of an inspection, as necessary to properly document
additional or modified BMPs designed to correct problems identified. Revisions to
the SWPPP must be completed within seven (7) calendar days following the
inspection.
Inspection Procedures
The inspection must include observation of the following:
The construction site perimeter and discharge points (including discharges
into a storm sewer system),
All disturbed areas,
Areas used for material storage that are exposed to precipitation,
Other areas determined to have a significant potential for stormwater
pollution, such as demolition areas or concrete washout areas,
Erosion and sediment control measures identified in this SWMP or on the
approved Grading and Erosion Control Plans,
Any other structural BMP’s that may require maintenance, such as
secondary containment around fuel tanks or the condition of spill response
kits.
Qualified Personnel
Inspections must be conducted by qualified personnel (provided by the
operator or cooperatively by multiple operators). “Qualified personnel” means a
person knowledgeable in the principles and practice of erosion and sediment controls
who possesses the skills to assess conditions at the construction site that could impact
stormwater quality and to assess the effectiveness of any sediment and erosion control
measures selected to control the quality of stormwater discharges from the
construction activity.
BMP Maintenance
Any BMP’s found to no longer function as needed and designed or have the
potential to fail without maintenance or modifications must be addressed as soon as
Page 12 of 13
possible to prevent discharge of pollutants. Inspection should also include
preventative maintenance to proactively ensure continued operation.
BMP Replacement and Additions
See attached Detail sheets for specific maintenance and replacement
requirements for individual BMP’s. Modifications to the erosion control plan and
BMP’s may be necessary from time to time based on site inspections, if site
conditions change, or if site conditions are found to be different than anticipated by
the Grading and Erosion Control Plan. Any additions or deletions of erosion control
measures should be documented on the site copy of the Grading & Erosion Control
Plans.
Record Keeping
A record of all inspections made shall be kept with the SWMP Report for a
minimum of 3 years. A sample BMP Checklist is included in the Appendix of this
report. If the SWMP administrator wishes to use a different Inspection Log format,
then the following information must be included:
1. The inspection date;
2. Names, titles, and qualifications of personnel making the inspection;
3. Weather information for the period since the last inspection (or since
commencement of construction activity if the first inspection) including a
best estimate of the beginning of each storm event, duration of each storm
event, approximate amount of rainfall for each storm event (in inches),
and whether any discharges occurred;
4. Weather information and a description of any discharges occurring at the
time of the inspection;
5. Location(s) of discharges of sediment or other pollutants from the site;
6. Location(s) of BMPs that need to be maintained;
7. Location(s) of BMPs that failed to operate as designed or proved
inadequate for a particular location;
8. Location(s) where additional BMPs are needed that did not exist at the
time of inspection; and
9. Corrective action required including implementation dates.
The inspection report must be signed.
Additionally, records of spills, leaks, or overflows that result in the discharge
of pollutants must be documented and maintained. Information that should be
recorded for all occurrences includes the time and date, weather conditions, reasons
for the spill, etc.
Post-Authorization Records
The following records must be maintained with the SWPPP following authorization
under this permit:
1. Dates when grading activities occur;
Page 13 of 13
2. Dates when construction activities temporarily or permanently cease on a
portion of the site; and
3. Dates when stabilization measures are initiated.
Employee Training
It is recommended that the contractor/sub-contractor responsible for site
construction be trained and certified as a Colorado Department of Transportation
Erosion Control Supervisor or equivalent.
Persons responsible for ongoing maintenance and inspections of permanent
stormwater quality improvements should be familiar with the Operations &
Maintenance Manual provided.
