Task 1: Monitoring performance of 700 Wood Street bioretention cell
Background
In Spring 2012, the City constructed a bioretention stormwater treatment cell at the Utility Service
Center (USC) located at 700 Wood Street to better understand the performance of bioretention systems
in Fort Collins. To date, most bioretention performance research has been completed in locations with
very different hydrology than Fort Collins (e.g. Wisconsin, North Carolina, Pennsylvania and the Pacific
Northwest) and the applicability of the results of.those research projects to semi -arid environments
such as Colorado is unknown. Given the City's pending proposal to require LID -type stormwater
facilities for future development, it is important to understand how these facilities will operate in Fort
Collins climate.
Objectives and Scope of Work
The primary objective of this task is to quantify runoff and pollutant removal achieved by the
bioretention cell for multiple precipitation events. To do so, CSU will monitor the quality and quantity of
bioretention cell influent and effluent for the 2013 monitoring season (approximately April 1-September
30). Stormwater samples will be submitted to a local laboratory and analyzed for total suspended
solids, nutrients (nitrogen/phosphorus) and metals (zinc, copper, lead). Based on historic precipitation
data, we can expect to collect data for about 8 precipitation events during this period; however the
actual number may be more or less depending on precipitation and bioretention cell performance. At
the end of the 2013 monitoring season, a progress report will be submitted documenting the
performance results.

Task 2: Monitoring of Street Runoff Quality
Background
The City is currently working on a "Green Streets Initiative' that, among other things, aims to reduce
stormwater pollution generated from roadways. An important aspect in planning effective stormwater
management strategies for "green streets" is understanding the types and levels of pollutants generated
specifically from roadways. This information can help identify appropriate LID/BMP techniques to
remove critical pollutants and provide estimates of the total amount of pollutants removed from
stormwater runoff using such techniques.
Objectives and Scope of Work
The objective of this task is to monitor stormwater runoff quality generated from roadways in Fort
Collins. The City has existing monitoring systems located at 262 E. Mountain Avenue that may be
retrofitted to monitor stormwater runoff quality and quantity generated from Mountain Avenue and
Walnut Avenue. Alternatively, these systems may be moved to a location on Remington Street where
the Green Streets Pilot Project is being planned. Stormwater samples will be submitted to a local
laboratory and analyzed for total suspended solids, nutrients (nitrogen/phosphorus) and metals (zinc,
copper, lead). Based on historic precipitation data, we can expect to collect data for about 8
precipitation events during this period; however the actual number may be more or less depending on
precipitation. At the end of the 2013 monitoring season, a progress report will be submitted
documenting the performance results.

Task 3: Evaluation of permeable pavement system maintenance
requirements
Background
Permeable pavement systems (PPS) are susceptible to clogging over time and regular maintenance is
recommended to maintain infiltration capacity of PPS. However, additional research is needed on
several fronts regarding PPS maintenance. First, the required frequency of maintenance is still largely
unknown. We believe that maintenance frequency will be dependent on the type of PPS and the
runon/PPS surface area ratio, however we have not been able to test this to date. Second, the overall
effectiveness of different PPS maintenance methods (sweeping/vacuuming, replacement of bedding
material, etc.) has not been studied. A better understanding of these issues will allow the City to
provide data -based recommendations/requirements for maintenance of PPS on public and private
properties that should reduce costs while maintaining system effectiveness. In 2013, the City is
expected to contract out maintenance of the PPS at Mitchell Block. The exact nature of maintenance is
yet to be determined. In addition, the owner of the pervious concrete installation at 215 Linden St.
(CTL) will begin sweeping/vacuum maintenance of the facility on a quarterly basis in 2013.
Objectives and Scope of Work
The objective of this task is to measure the effectiveness of PPS maintenance activities and the rate at
which infiltration capacity of PPS is lost after maintenance. To accomplish this objective, CSU will
perform infiltration tests at both sites throughout 2013. Approximately 5 tests will be conducted at
each site. At CTL, six different rounds of testing will occur; one prior to and one after each of three
maintenance intervals. At Mitchell Block, 4 different rounds of testing will occur; one prior to and one
after maintenance that is schedule to be performed in spring 2013, followed by 2 more tests spaced out
approximately every 60 days. The effectiveness of maintenance activities will be assessed by comparing
pre- and post -maintenance infiltration rates and the rate of infiltration capacity loss will be evaluating by
measured infiltration rates over time. Results of this task will be submitted to the City in a
memorandum.

Task 4: Low -Impact -Development (LID) and Traditional Development
Cost Comparison in Fort Collins
Background
The City will soon require LID techniques to be implemented for new development and is interested in
gaining a better understanding of the construction and long-term operation and maintenance (O&M)
costs of using LID versus traditional stormwater management techniques. Studies comparing traditional
and LID construction costs have shown LID development to be 15-80%cheaper to construct, with a few
exceptions'. However, these studies did not include the long-term O&M cost estimates.
The Foothills Mall redevelopment and Green Streets Pilot Project are two projects currently in the
development phase that are planning for extensive use of LID techniques. These projects present an
opportunity to investigate the life cycle costs of using traditional stormwater management strategies
versus LID -type development in real -world applications.
Objectives and Scope of Work
The objective of this study is to develop stormwater-related life -cycle cost estimates for two
redevelopment projects in the City of Fort Collins. For both projects, life -cycle costs estimates will be
developed for two scenarios; one that utilizes extensive use of LID infrastructure and another that
utilizes traditional stormwater infrastructure (e.g. curb -and -gutter, underground conveyance,
centralized BMP treatment). CSU will use actual design and cost information to the extent that it is
available (such as for the current Foothills Mall redevelopment), supplemented with design and cost
information developed by CSU. The findings will be submitted in a report to the City.

EXHIBIT A
Proposal: Cache la Poudre River Post -Fire Sediment & Aquatic Insect Monitoring Oct 31, 2012
Statement of Work
CACHE LA POUDRE RIVER POST -FIRE SEDIMENT & AQUATIC INSECT
MONITORING
Co -Principal Investigators:
Daniel W. Baker, Department of Civil & Environmental Engineering, Colorado State University
Brian P. Bledsoe, Department of Civil & Environmental Engineering, Colorado State University
Proiect Background:
The wildfires of 2012 burned over 66,000 acres (around 10%)of the Cache la Poudre River
watershed. As a river historically confronted by combined pressures of decreased flows and
adjacent development, the effects of the 2012 fires will only further alter channel conditions and
possibly shift the river's overall health. As stewards of this ecological commodity, the City of
Fort Collins, Colorado Parks & Wildlife (CPW), and Colorado State University (CSU) are
collaborating to better understand these changes in an effort to both more clearly communicate
with the diverse public and make more informed management decisions. Within the canyon, the
Cache la Poudre is valued for its scenic beauty, fisheries, boating opportunities, and as a source
of clean mountain water for municipal consumptive use. The lower -energy reach through Fort
Collins is often used for fishing, tubing, swimming, and the aesthetic appreciation of countless
others. These two sections of the Poudre are likely to be affected to different degrees and over
distinct time scales by the post fire sediments. As such, this study will examine the amount and
condition of both fine sediments and aquatic insect communities through a coordinated quarterly
sampling program at nine sites along both sections of the river.
Proiect Goals and Obiectives:
Excessive sediment within rivers degrades the quality of aquatic habitat, diminishes watershed
functions and services, reduces the flood conveyance capacity, and limits the aesthetic, social,
and economic value of aquatic ecosystems. The adverse impacts of suspended and deposited
sediment include reduced water quality, increased water treatment costs for municipal supply
and industrial processes, diminished river and reservoir capacity, increased costs for maintenance
of irrigation canals, and reduced habitat for fish and benthic macro invertebrates. Sediment is not
only a critical pollutant, but is also a catalyst, carrier, and storage agent for other forms of
pollution. Excessive deposition of fine sediment can impair aquatic life in a variety of ways. For
example aquatic insects such as mayflies and stoneflies depend on clean interstitial spaces
between gravels and cobbles in the river bed to carry out their life cycles (Waters 1995), and
sediment infilling of critical habitat like pools and gravel spawning beds decreases the survival
rate of fish and fish embryos(Chapman 1988, Suttle et al. 2004).These effects can also propagate
out of the channel to the riparian ecosystem as birds and other animals depend on aquatic insects
as a food source. Combined with the reduction in flushing flows vegetation encroachment on the
new nutrient rich sediments may further exacerbate flooding potential.
Flow regime is a master variable in controlling the effects of excessive sediment delivery on the
river ecosystem. Moderate to high flows in the Cache la Poudre River support many amenities
including clean water, fisheries, recreational opportunities and aesthetic benefits. Such flows can
mitigate the excessive accumulation of fine sediments, and maintain habitats, channels, riparian
Proposal: Cache la Poudre River Post -Fire Sediment & Aquatic Insect Monitoring Oct 31, 2012
corridors, and hyporheic/groundwater connections that moderate stream temperatures (Whiting
2002). Depletions of moderate to high flows have altered the capacity of the Cache la Poudre
River to maintain physical habitat for fishes and aquatic insects by reducing the number of days
on average that flows exceed the thresholds necessary to flush fine sediment and scour the river
bed. The period of years between flushing events is now longer than what river biota are adapted
to in terms of habitat availability and reproduction. Sediment influx from the High Park and
Hewlett fires may increase the vulnerability of the river to flow depletions, and proposals for
additional diversions will continue into the future. Accordingly, there is a pressing need to
improve understanding of the linkages between sedimentation impacts and aquatic biota, as well
as quantifying the flushing flows required to achieve biological objectives in the future.
With these needs in mind, the project objectives are to:
1. Quantify surface and bulk accumulation of fine sediment along a gradient of sediment
input, flow alteration, and geomorphic setting.
2. Link response of aquatic insects to fine sediment accumulation in the substrate through
coordinated sampling.
3. Quantify the fine sediment removal and habitat improvement achieved by flushing flows
of different magnitudes and durations of moderate to high flow.
4. Complement other post -fire studies including those investigating local salmonid
populations, water quality, and high resolution remote sensing data of the burned areas.
5. Inform the public of the current and evolving conditions of the Cache la Poudre River
ecosystem
Project Scheduling
Refer to the task schedule timeline below, for a preliminary schedule of tasks.
Statement of Work
We propose to start with a 2 year monitoring program (with this round of funding covering the
IS` year). Inter -annual variability in the snowmelt hydrograph provides a natural experiment that
allows us to examine the extent of benthic habitat recovery and sediment transport with varying
magnitudes and durations of high flow. The proposed three monitoring phases would be timed
with the snowmelt hydrograph: (1) during fall baseflow, (2) preceding the spring runoff, and (3)
on the falling limb of the hydrograph peak. A potential 4th sampling event (as the budget
allows) could be initiated if there is a spike and then reduction before peak.
The proposed monitoring plan is extensive due to various challenges. First, anthropogenic flow
extraction and floodplain alteration coupled with the natural geomorphic process shifts along the
river corridor create a wide variety of channel types. Second, the ability to detect differences in
fine sediment on the channel bed requires extensive monitoring efforts (Baker et al. 2011).
Finally, there is a wide array of potential stakeholders in this project with differing desires and
needs.
Project tasks include:
1. Develop sampling protocol
2. Field data collection and analysis
3. Write-up of findings

Stormwater Related Research Services
Introduction
City of Fort Collins Utilities (City) has requested research services from the Colorado State University
(CSU) Urban Water Center to improve the understanding of stormwater management practices within
the City. Four tasks have been identified for the 2013 year; 1) monitoring of the performance of a
recently constructed bioretention cell, 2) monitoring of runoff generated from urban streets, 3)
evaluation of the permeable pavement clogging and the effectiveness of maintenance and 4) life cycle
cost comparison of new development using low impact development (LID) and traditional stormwater
management techniques. A complete description of the objectives, scope and budget of each task are
provided on the following pages.
