The linetype differences between
existing and proposed are not clear
enough. They look almost identical,
and it makes the plans less clear.
The linetypes should be more
consistent. Why does the proposed
gas linetype look thinner than the
existing, but the proposed electric
linetype is thicker than existing?

Remove all brick pavers from the
roundabout. The City does not want
pavers anywhere in the public
ROW. The City will not maintain any
brick pavers within the ROW, and it
does not make sense to split out
maintenance responsibilities for the
small areas within the roundabouts.
Should the regional
trail be marked to
clearly define it's
path? Colored
concrete and/or
signage added, since
it is different from the
rest of the sidewalks?
Please label these
existing contours

The City is not comfortable with brick pavers in the public
ROW. If the Montava team wants to keep the brick paver
roadways, you will have to make these streets private
instead of public. The City will not provide roadway
maintenance, nor plow the snow or salt the streets in the
winter.
Instead of providing right-of-way, you will need to provide
public access easements, and a utility easement for any
public utilities that are located under these brick paver
roadways.
Coordination of utility maintenance that will occur and the
responsibilities of replacing brick pavers will be written in to
the Development Agreement.

Where does this go?
Is there a detention
pond here?
Was it intentional
that there is no
sanitary sewer
proposed in
Godwink Dr? Will
future development
southeast of
Godwink Dr be
served by an
extension of the
sewer in Montava

Minimum K value at a sag on a minor collector is
64. Although this is a future improvement to be
constructed under another phase, we cannot
approve plans that show a design that does not
meet LCUASS standards. Either revise the
vertical curve design to make the k-value equal
to or greater than 64, or remove this VC label
from the plans and fix the vertical curve later.
Vertical curves should not overlap with horizontal curves.
Additionally, 100' is not long enough for a vertical curve
in a collector street -- please review LCUASS Figure
7-17 using a collector design speed of 40 mph.

Montava Subdivision Phase E: Town Center Stormwater Management Plan
Page 1
1.0 - Site Description
1.1 Introduction
The following Storm Water Management Plan (SWMP) has been prepared for use during the
construction of the Montava Subdivision Phase E project. This plan describes recommended
procedures and best management practices, BMP’s, to assist the contractor in complying with
the Colorado Water Quality Control Act and the Federal Water Pollution Control Act. A copy of
the CDPHE General Permit for discharge is attached in Appendix A. The general permit is the
State law that requires this report and is provided for reference. A copy of the permit application
is provided in Appendix B for submittal to the State at least 10 days prior to beginning
grading activities. The intent of this plan is to provide the contractor a place to consolidate
records, logs, permits, applications etc. as well as guidance on water quality protection. It is
critical that the contractor understands that this plan is a living document that must be
updated and maintained throughout the construction process.
1.2 Project Location and Description
The Montava Subdivision Phase E: Town Center project site is located in Section 32, Township
8 North, Range 68 West of the 6th Principal Meridian, within the City of Fort Collins, Larimer
County, Colorado. The proposed site is bounded on the north by farmland and Future Montava
Subdivision phases, on the east by farmland, N. Giddings Road, and Future Montava
Subdivision phases, on the south by Mountain Vista Drive and farmland, on the west by the
Number 8 Outlet Ditch and Montava Subdivision phase G and Future Montava Subdivision
phases. The Montava Subdivision Phase E: Town Center project site contains approximately
39.00 acres and consists of the Multi-Family, Townhomes, Duplex, Single Family, Mixed-Use,
and Open Space. The Montava Subdivision Phase E: Town Center is currently zoned as Low
Density Mixed-Use Neighborhood District Flexible Overlay Zone (LMN).
A vicinity map illustrating the project location is provided in Figure 1.1.
Montava Subdivision Phase E: Town Center Stormwater Management Plan
Page 4
Stoneham loam (101) – 1 to 3 percent slopes.
Stoneham loam (102) – 3 to 5 percent slopes.
Stoneham Loam (103) – 5 to 9 percent slopes.
The characteristics of the soil found on the project site include:
Moderate infiltration rate when thoroughly wet.
Moderately fine texture to moderately coarse texture.
Moderate rate of water transmission.
These soils consist of the following hydrologic soil groups as defined in the United States
Department of Agriculture (USDA), Web Soil Survey:
Group B – 18.70%
Group C – 24.30%
Group D – 57.00%
The USDA web soil survey report is included in Appendix G.
1.5 Wetlands and Receiving Waters
The Montava Subdivision Phase E is located in development is a 20.8-acre undeveloped lot
west of the Anheuser Busch property. According to FCSCM, runoff from the undeveloped site
generally sheet flows in the southeasterly direction towards the Larimer and Weld Canal
Montava Subdivision Phase E is located in. See the Martin/Martin Master Drainage Study for
more information about the existing conditions. According to the Montava Master Drainage
Study, Montava Subdivision Phase E is primarily located within Basin F, Basin G1, and Basin
G2. The portion of Montava Subdivision Phase E located in Basin F will generally flow
southeasterly into a pond designed with the Master Drainage Study. The portion of Montava
Subdivision Phase E located with Basin G1 will generally flow southeast and into a pond
proposed with the Master Drainage Study. The portion of Montava Subdivision Phase E located
in Basin G2 will generally flow southwest into a proposed pond and outfall directly into the
Number 8 Ditch. These existing drainage patterns were maintained with the development of the
Montava Subdivision Phase E project.
The proposed Montava Subdivision Phase E development generally maintains existing drainage
patterns. The entirety of the site will continue to flow northwest through proposed storm
infrastructure to the location of the existing detention pond. The existing detention pond will be
increased in size to over-detain runoff from the developed condition of the site. An outlet

structure will attenuate storm runoff to a historic rate of 0.04 cfs/acre. The outlet structure will
outlet into an existing swale northwest of the site.
1.6 Storm Water Management Plan Administrator
_________________________ shall be the designated SWMP Administrator for the Project. It
will be his or her responsibility to insure the SWMP's adequacy at all times to effectively manage
potential storm water pollutants throughout the course of construction.
1.7 Potential Pollutants
Below is a list of potential pollution sources that can occur during the construction of site
improvements and potential remedies, or the appropriate section that should be referenced for
controlling these pollution sources:
All disturbed and stored soils – (Surface roughening, reseeding, mulching and silt
fence)
Vehicle tracking of sediments – (Vehicle tracking pads, street sweeping)
Management of contaminated soils – (See Section 2.3.2)
Loading and unloading operations – (See Section 2.2.3 - Stabilized Staging
Area)
Outdoor storage activities (building materials, fertilizers, chemicals, etc.) – (See
Section 2.3)
Vehicle and equipment maintenance and fueling - (See Section 2.3.2)
Significant dust or particulate generating processes – (See Section 2.2.3 – Wind
Erosion/Dust Control)
Routine maintenance activities involving fertilizers, pesticides, detergents, fuels,
solvents, oils, etc. (See Section 2.3.2)
On-site waste management practices (waste piles, liquid wastes, dumpsters,
etc.) – (See Section 2.3)
Concrete truck/equipment washing, including the concrete truck chute and
associated fixtures and equipment - (Use concrete wash-out)
Dedicated asphalt and concrete batch plants – (Not used on this project)
Non-industrial waste sources such as worker trash and portable toilets – (See
Section 2.3.2.- BMP’s for San/Septic Waste)
Other areas or procedures where potential spills can occur (See Section 2.3)
2.0 - Pollution Controls
Montava Subdivision Phase E: Town Center Stormwater Management Plan
Page 6
2.1 Controls Overview
During construction, several control measures shall be implemented under the direction of the
contractor to prevent discharge of contaminated water. Specifications and details for specific
control measures are included in Appendix C of this report for use on the project. In addition to
those structural measures, other controls include non-structural practices, materials
management, spill prevention and management, and other miscellaneous controls as described
in the following sections.
2.2 Erosion and Sediment Controls
The objective of erosion control is to limit the amount of erosion occurring on disturbed areas
until stabilized. The objective of sediment control is to capture soil that has eroded before it
leaves the construction site. Despite the use of both erosion and sediment control measures, it
is recognized that some sediment could remain in runoff, especially during very large storm
events. The contractor shall utilize the best management practices (BMP’s) described in the
following sections to minimize the above potential to the maximum extent practicable.
During all phases of construction, the contractor should plan ahead of possible rainfall events
and work to limit erosion from occurring where potential exists. Where potential does exist
provide adequate conveyance, temporary or permanent, and direct runoff to BMP’s that trap
sediment. The erosion and sediment BMP’s anticipated for use on the site include both
structural and non-structural practices.
2.2.1 Structural Practices
Structural BMPs are structures that limit erosion and sediment transport. Such
Practices include check dams, silt fence, inlet and outlet protection, water quality ponds, and
grading techniques. The structural BMP’s that will be utilized on the subject site are described
in more detail as follows:
Check Dams
Can be constructed of rock, gravel bags or sandbags across a swale or channel
Used to slow the velocity of concentrated flow in a channel and reduce erosion
Used to catch sediment by capturing contaminated runoff
Most effective when used with other erosion prevention BMPs
Should not be used for basins exceeding 2-5 acres
Should be used in series with the base elevation of the upstream dam set at the
same elevation or lower than the downstream dam.
Sediment Control Logs (Wattles)
Montava Subdivision Phase E: Town Center Stormwater Management Plan
Page 10
present. Implementation of tire washing should include provisions for collecting
wash water and directing it to a treatment pond
Whenever possible locate the construction entrance as far from the disturbed
area as possible to allow maximum travel time for sediment removal from tires.
Public and Private roadways shall be kept clear of accumulated sediment.
Cleaning sediment shall not be accomplished by flushing with water. Sediment
should be shoveled or swept from the street and placed away from storm water
improvements.
Consider limiting vehicles from entering the site when conditions are wet or
muddy.
Wind Erosion / Dust Control
Dust from the site will be controlled using a mobile pressure-type distributor truck
to apply portable water to disturbed areas. The mobile unit will apply water only
as necessary to prevent runoff and ponding.
Dust control will be implemented as needed once site grading has been initiated
and during windy conditions while site grading is occurring.
Spraying of portable water will be performed whenever the dryness of the soil
warrants it.
At least one mobile unit will be available at all time to distribute portable water to
control dust on the project area.
During high winds limit traffic speeds to 12 mph or less on areas without gravel or
pavement.
Gravel can be placed on construction roads, entrances, and construction staging
areas. Stone/gravel provides an effective protective cover over the soil.
In areas where wind erosion is expected soil-binding tackifiers can be applied
with high success.
Stabilized Staging Area
A clearly designated area where construction equipment and vehicles, waste
bins and other construction related materials are stored
This area should be designated on the SWMP map.
Appropriate space to provide loading/unloading operations and parking
A stabilized surface, paved or covered in 3” diameter aggregate or larger
Perimeter controls such as silt fence, sediment control logs or construction
fencing
Vehicle Tracking Control pad to be used in conjunction with a Stabilized Staging
Area if this area is adjacent to a public roadway
Dewatering Operations
Dewatering typically involves pumping water from an inundated area to a BMP

Uncontrolled releases of mud or muddy water or measurable amounts of
sediment
An estimated amount of precipitation. An onsite rain gauge is suggested.
3.4 Site Maps
In the back pocket of this report notebook there is an Erosion Control Plan for use during
construction. The purpose of this plan is to provide the contractor a place to document and plan
BMP’s used during construction. Because the placement of individual BMP’s will depend on the
condition of the site and the contractor’s judgment, not all BMP’s are shown on the plans. It is
the contractor’s duty as site administrator to determine the need for and placement of BMPs and
mark them on the map.
4.0 - Final Stabilization / Conclusion
Permanent stabilization will be achieved by establishing vegetative or permanent surface cover
on all disturbed areas. The final vegetative cover is specified on the Erosion Control Plan.
Vegetative cover is considered complete when 70 percent of the pre-disturbance plant density is
restored. In cases where the site was already disturbed, the existing gravel ponds for example,
the pre-disturbance density will be the naturally occurring cover on currently vegetated areas.
The contractor shall remove all temporary erosion and sediment control BMPs after stabilization
is achieved or after temporary BMPs are no longer needed. Trapped sediment (including within
pipes) will be removed by the contractor or stabilized onsite. Disturbed soil areas resulting from
removal of BMPs or the contractor will permanently stabilize vegetation as soon as possible.
Again, this plan is a living document that will need to be updated and maintained
throughout the construction process and until all areas of the site have been stabilized.
This permit will remain active until an inactivation notice has been filed with the State.
Additionally, this permit may be transferred to another party in the event that the contractor or
sub-contractor responsible for its implementation leaves the site before stabilization has
occurred. The Inactivation Notice and Reassignment Notices are included in Appendix F.
