1.1.2 Nature of Construction
The project consists of construction of a hotel building, parking lot and infrastructure on the site.
The stormwater runoff will be directed to the south via overland flow to the proposed detention
ponds which drain into the Cache La Poudre River. The Limits of Construction (LOC) for the work
have been established on the Erosion Control Plan. The project will provide permanent
stabilization through vegetation on all disturbed areas.

The earthwork cut and fill quantities are based on the difference between finished and existing surfaces,
including a fill factor of 1.20, and should not to be used for bidding purposes.
1.1.5 Soils
According to the NRCS Soil Survey conducted for the area of interest, soils for the project
consist of:
• Loveland Clay Loam, 0 to 1 percent slopes
Spirit at the River Hotel, SWMP
Spirit at the River Hotel 017-0150
3
Loveland Clay Loam with a slope between 0 and 1 percent containing a whole soil K-Factor of
0.20, exhibit a risk for sheet and rill erosion. These soils are classified as Hydrologic Group A and
have a Wind Erodibility rating of 6, which indicates that the soil has a low susceptibility to wind
erosion.
1.1.6 Drainage Patterns
Drainage patterns will be altered to direct flows to the proposed detention ponds. The detention
pond will be released into the Cache La Poudre River.
1.1.6.1 Pre-Construction Drainage Patterns
In the existing conditions, runoff flows south towards the Cache La Poudre River. Currently the
site has an office building, workshop, multiple storage sheds, paved parking lot, and a gravel
storage area and has slopes from 0 to 1 percent.
1.1.6.2 Post Construction Drainage Patterns
Due to the proposed changes in site grading, the site will drain to the south where runoff will be
collected in the detention ponds.
1.1.7 Receiving Body of Water(s)
The existing site drains to the Cache La Poudre River to the south. The Cache La Poudre River
is classified as impaired. Information about this is provided in the following tables:

2.1.4 Non-Stormwater Discharges
In accordance with I.D.3.b. of the CDPS General Permit for Stormwater Discharges Associated
with Construction Activity, discharges from the following sources that are combined with
stormwater discharges associated with construction activity may be authorized by the Stormwater
Construction permit, provided that the non-stormwater component of the discharge is identified in
the SWMP (see Part I.C.1.g of the permit):
• Emergency firefighting activities
• Landscape irrigation return flow
• Uncontaminated springs
• Discharges to the ground of concrete washout water from washing of tools and concrete
mixer chutes are allowed under this SWMP, provided that: the washout water is confined
in a concrete washout area and does not leave the site as surface runoff or to surface
waters, and does not connect directly to the groundwater table.
• Certain construction dewatering discharges. The WQCD’s General Permit for Stormwater
Discharges from Construction Activities allows for dewatering of groundwater and
stormwater to the ground surface to allow for infiltration on the site. No groundwater from
construction dewatering will be discharged as surface runoff or to surface waters on the
site. It is not anticipated that dewatering activities will be required during this project.
However, if dewatering becomes necessary, groundwater and/or stormwater may be
pumped from excavations or trenches to the ground surface on the site for infiltration or
evaporation. The location of pumping and deposition of the groundwater or stormwater
will be marked on the site plan prior to the start of pumping activities. If it becomes
necessary to pump groundwater off site or into a waterway or storm sewer, then a
groundwater discharge permit must be obtained from the State prior to engaging such
activities.
The following table lists remaining non-stormwater discharge activities and the associated BMPs
(structural and non-structural) used to minimize and eliminate discharge of pollutants.

Please note that vehicle fueling/washing, concrete waste management, construction dewatering,
sanitary/septic waste management are all addressed in Section 2.1.4. of this SWMP.
Solid Waste Management
Solid waste management procedures and practices are designed to prevent or reduce the
discharge of pollutants to stormwater from solid or construction waste by providing designated
waste collection areas and containers, arranging for regular disposal, and training employees and
subcontractors.
All waste materials will be collected and stored in a securely lidded dumpster. All trash and
construction debris from the site will be deposited in the dumpster. The dumpster shall meet all
local, State, and Federal solid waste management regulations. The dumpster will be emptied a
minimum of twice per week by a qualified and licensed solid waste management contractor, and
will be hauled to an approved dumping site. No construction waste materials will be buried on the
project site. All personnel will be instructed regarding the correct procedure for waste disposal.
Notices stating these practices shall be posted on the job site. The SWMP Administrator will
ensure these practices are being followed.
Hazardous Materials Management
Prevent or reduce the discharge of pollutants to stormwater from hazardous waste through proper
material use, waste disposal, and training of employees and subcontractors.

• Inspection and Maintenance
Liquid Waste Management
Liquid waste management includes procedures and practices to prevent discharge of pollutants
to the storm drain system or to watercourses as a result of the creation, collection, and disposal
of non-hazardous liquid wastes.
The responsible parties shall manage Liquid Waste on site by implementing the following
five BMPs to Liquid Waste Management:
• Education
• Containment
• Capture
• Disposal
• Inspection and Maintenance
Material Storage
The purpose is to prevent, reduce, or eliminate the discharge of pollutants from material storage
to the stormwater system or watercourses by minimizing the storage of hazardous materials on-
site, storing materials in a designated area, installing secondary containment, conducting regular
inspections, and training employees and subcontractors.
The site will designate a specific location where the Material Storage Area or areas will be located.
The following BMPs will be implemented at each Material Storage location on site:
• Designate entrance and exit points.
• Install vehicle tracking control at entry and exit point(s)
• Appropriate perimeter BMPs need to be installed.
All materials must be properly and tightly sealed in original containers with manufacturer’s label
for identification. Damaged or illegible labels should be replaced immediately.
Materials must be stored at a minimum on pallets, but preferably in secondary containment to
prevent any leaks or spills to exit into the ground or come into contact with stormwater.
Materials preferably will be stored under a cover or tightly secured tarp to prevent contact with
stormwater.
The Material Storage Area must be inspected at a minimum during regularly scheduled
stormwater inspections. Inspector should pay close attention to any signs of leaks or spills.
Spill kits should be present at the Material Storage Area.
All on site workers shall be trained and educated in proper material handling and storage prior
to conducting any work with materials.

3.0 BEST MANAGEMENT PRACTICES
3.1.1 Purpose
Section 3.0 of this Stormwater Management Plan will identify the Best Management Practices
associated with the project. This section will call out phasing of the BMPs that will coincide with
the sequencing for major construction activities on the site. A section of technical drawings and
installation specifications of each BMP will also be included.
Note to SWMP Administrator: It is the responsibility of the SWMP Administrator to ensure
all BMPs called out in this plan are adequate for the current conditions on site. It is the
responsibility of the SWMP Administrator to make necessary changes to the SWMP
concerning BMPs, when BMPs are replaced or new BMPs are needed on site due to
changing site conditions in order to keep the site in compliance with the stormwater
permit.
3.1.2 Description and Maintenance
Structural and non-structural BMPs shall be implemented on site to help prevent erosion and
sedimentation. Below is a description of each on site BMPs purpose, limitations, installation,
inspection, and maintenance requirements.
Temporary and permanent erosion sediment controls shall be used to provide soil stabilization
and divert stormwater runoff for both pre- and post-construction conditions. Structural controls,
such as fugitive dust mitigation and a concrete washout area will be used to limit off-site tracking
of sediment during construction onto Lincoln Ave.
All BMPs used on site must be maintained in effective operating condition and in accordance with
good engineering, hydrologic, and pollution control practices. During routine inspections, the site
BMPs must be inspected for their effective operating condition. If a BMP or several BMPs are
found not to be operating effectively, maintenance to those BMPs must be initiated immediately.
Replacement of failed BMPs must occur immediately upon findings of noncompliance and failed
performance of any particular BMP on the project site. New BMPs that are installed or replaced
will result in a need to properly update the SWMP and the site map to show the changes.
Note: CONTRACTOR SHALL TAKE ALL NECESSARY MEASURES DURING UTILITY
INSTALLATION TO ENSURE THAT SEDIMENT IS NOT RELEASED FROM THE SITE. TO
INCLUDE, BUT NOT LIMITIED TO: UTILITY TRENCHES EXIST ONLY FOR INSTALLATION
OF CORRESPONDING UTILITIES. SPOILS SHALL BE PLACED ON THE UPHILL SLOPE
SIDE OF THE TRENCH.

3.1.3 Water Quality Control Plan
Several temporary sedimentation and erosion control devices will be used during construction to
reduce the amount of sediment transport from and across the site. During Phase 1, silt fence will
be installed along the perimeter of the site, wattles will be installed up slope of the silt fence along
the river, vehicle tracking control, stabilized staging area, concrete washout and the inlet
protection for the rain garden in Lincoln Avenue just west of the project site. This will protect the
Cache La Poudre from any sediment release from the construction site. While construction is
underway the BMP’s in place will work in conjunction such that if one fails there will be redundant
measures to prevent any sediment from reaching the river. During Phase 2, a treatment train of
redundant BMP’s are in place starting with rock check dams, then to inlet protections, running into
the sediment basin, wattles up slope from the river, and silt fence around the disturbed area of
the site. In Phase 3 the treatment train of redundant BMP’s starts in the north with rock check
dams and runs south past inlet protections, towards the rain garden which is surrounded by
wattles. Silt fence is also in place along the outside of the site disturbed area with wattles up slope
from the river. For the Phase 4 treatment train, the site will be seeded and mulched in all
landscaped areas, and sediment erosion will be limited and mitigated by the detention pond and
rain gardens, and the outfall to the river will be controlled by the pond outlet structure. The
detention pond will serve as a sediment basin during overlot grading and until Phase 3. The Inlets
noted on the plan sheets along Lincoln Ave impacted by the project will be protected with BMP’s
through Pase2 and 3 to mitigate sediment pollution into existing storm systems. Once the
Infrastructure and hardscape are installed in Phase 3 the sediment basin will converted over to
the detention pond and rain garden. The rain garden will be protected by wattles until the site is
completely stabilized in Phase 4. In Phase 4, seed and mulch will be installed to stabilize slopes
and allow vegetation after construction is completed.
Permanent stormwater quality features incorporated into this development include one extended
detention basin and one rain garden. The rain garden is located in the bottom of the extended
detention basin. The detention facility is designed to treat the water quality capture volume in the
Rain Garden. The Rain Garden is designed to drain within 12 hours.
3.1.4 Phasing and Sequencing
The following table lists the phases of construction for the Project and the implementation of
structural and non-structural BMPs associated with the particular phase of construction. The
phases are defined as follows:
• Phase 1: Initial / Pre-Overlot Grading phase
• Phase 2: Overlot Grading and Vertical Construction Phase
• Phase 3: Infrastructure Phase, paving, curb and gutter
• Phase 4: Final Stabilization and Permanent BMPs

Sediment/Erosion
control BMP
Phase of
Construction
Description*
Silt Fence 1-3
A woven geotextile fabric attached to wooden posts and
trenched into the ground. Its purpose includes intercepting sheet
flow runoff from disturbed areas.
Vehicle Tracking
Control
1-3
Provides stabilized construction site access where vehicles exit
the site onto paved public roads. An effective vehicle tracking
control helps remove sediment (mud or dirt) from vehicles,
reducing tracking on the paved surface.
Stabilized Staging
Area
1-3
A designated area where construction equipment and vehicles,
stockpiles, waste bins, and other construction related materials
are stored.
Concrete Washout
Area
2-3
Concrete waste management involves designating and properly
managing a specific area of the construction site as a concrete
washout area. A concrete washout area is one of the following:
excavation of a pit in the ground, use of an above ground
storage area, or use of prefabricated haul away concrete
washout containers.
Inlet Protection 2-3
Permeable barriers installed around an inlet to filter runoff and
remove sediment prior to entering a storm drain inlet. Can be
constructed from rock socks, sediment control logs, silt fence,
block and rock socks, or other materials approved by the local
jurisdiction.
Seed & Mulch 2-4
Seeding includes preparing a seedbed selection of an
appropriate seed mixture, proper planting techniques and
protection of the seeded area with mulch. Seeding is used to
stabilize areas that will be inactive for an extended period. Mulch
consists of evenly applying straw, hay, shredded wood mulch,
rock, bark or compost to disturbed soils and securing the mulch
by crimping, tackifiers, netting or other measures. Mulch is used
to help reduce erosion by protecting bare soil from rainfall
impact, increasing infiltration, and reducing runoff.
Stock Pile 1-3
Stockpiles should be located away from all drainage systems. If
practical use undisturbed areas. The stockpile surface shall be
stabilized with surface roughening, temporary seeding and
mulching, erosion control blankets, or soil binders. Seeding and
mulching will be used to prevent wind erosion. When the
stockpile is no longer needed, dispose of the excess materials
and revegetate area.

4.0 FINAL STABILIZATION
4.1.1 Purpose
Section 4.0 of the SWMP details how the site will achieve final stabilization/re-vegetation for the
project. It is required by the permit for Stormwater Discharges associated with Construction
Activities that final stabilization will be achieved when all ground disturbing activities are
completed and a uniform vegetative cover has been established with an individual plant density
of at least 70% pre-disturbance level, or equivalent permanent, physical erosion reduction
methods have been employed.
Note to SWMP Administrator: The removal of temporary BMPs must not take place until
the site has completed ground disturbing activities and a uniform vegetative cover has
been established in the designated re-vegetation areas with the individual plant density of
70% pre-disturbance levels.
Note: Landscaping shall be installed per the landscape plan.
Site Specific Re-Vegetation Plan
The re-vegetation plan for the project consists of landscaping and seeding and mulching (if
necessary) upon completion of all construction activities. All disturbed areas not covered by gravel
paving or the building pad shall be seeded & mulched or landscaped per the enclosed erosion
control plan and accompanying notes.
Areas in close proximity to Natural Areas will use a Native Seed Mix. Refer to following notes for
proper native seed area installation:
1. Prepare soil as necessary and appropriate for native seed mix species through aeration and
addition of amendments, then seed in two directions to distribute seed evenly over entire area.
2. If changes are to be made to seed mix based on site conditions then approval must be provided
by city environmental planner.
3. Appropriate native seeding equipment will be used (standard turf seeding equipment or
agriculture equipment shall not be used).
4. Drill seed application recommended per specified application rate to no more than 1/2 inch
depth. For broadcast seeding instead of drill seeding method double specified application rate.
Refer to native seed mix table for species,
Percentages and application rates.
5. Treat native seed mix area prior to installation of seed with appropriate herbicide to proactively
mitigate herbaceous weed species growth during establishment period then after appropriate time
period apply native seed as called for
On approved plans.
6. After seeding the area shall be covered with crimped straw or other appropriate methods and
provided temporary irrigation until seed is established.
7. Contractor shall monitor seeded area for proper irrigation, erosion control, germination and
reseeding as needed to establish cover.

8. The approved seed mix area is intended to be maintained in a natural like landscape aesthetic.
If and when mowing occurs in native grass seed mix areas do not mow lower than 6 to 8 inches
in height to avoid inhibiting native plant growth.
9. Native seed area will be considered established when seventy percent total cover is reached
with no larger than one foot square bare spots and/or until deemed established by city planning
services
The project will utilize sod, ornamental grasses, native plantings, rock mulch, trees, and shrubs
as a final stabilization method of all disturbed areas.
Note to SWMP Administrator: It is the responsibility of the SWMP Administrator to oversee
seeding operations to ensure proper application for expected growth.
4.1.2 Post-Construction BMPs
Post Construction BMPs or permanent structures that will remain on site include permanent
landscaping. An Operating and Maintenance manual may be developed in accordance to the
CDPHE requirements and can thus be referenced for future maintenance procedures. Phasing of
the stabilization plan, changes in inspection frequency, and closing of the CDPS permit shall be
documented.

Temporary grade control structures placed in drainage areas to
limit erosivity of stormwater by reducing flow velocity. Typically
constructed from rock, gravel bags, sandbags, or sometimes
proprietary devices.
Wattles 3
A linear roll made of natural materials such as straw, coconut
fiber, or other fibrous material trenched into the ground and held
with a wooden stake. Used as sediment barriers to intercept
sheet flow runoff from disturbed areas.
Sediment Basin 1-2
A temporary pond built on a construction site to capture eroded
or disturbed soil transported in storm runoff prior to discharge
from the site.
