SUBJECT
Resolution 2016-012 Authorizing an Intergovernmental Agreement with Colorado State University for
Stormwater Related Research Services.
EXECUTIVE SUMMARY
The purpose of this item is to obtain Council approval for a new City-Colorado State University (CSU)
agreement in the amount of $65,840 for stormwater related research services that would be provided by CSU
to the City in 2016.
STAFF RECOMMENDATION
Staff recommends adoption of the Resolution.
BACKGROUND / DISCUSSION
Starting in 2008, Utilities and Streets staff have contracted with the CSU College of Environmental and Civil
Engineering for a series of research studies aimed at improving the City’s knowledge base and operational
efficiency in the area of water quality management and treatment as they are affected by Streets’ operations
treatment. The studies are also meant to help protect and enhance the City’s water resources as they are
affected by runoff from stormwater sources.
The original term of the contract expired at the end of 2012. Since then the City and CSU have mutually
extended the contract on an annual basis in an effort to address Council directives regarding water quality
improvements and respond to changing technologies in the fields of Low Impact Development (LID) and water
quality treatment in general.
The subjects of the proposed CSU research efforts include an LID water quality and quantity monitoring of a
bioretention facility, possible process improvements to the City’s deicing program through a winter runoff
monitoring program, an investigation of nutrient sources in urban stormwater, and possible updates to the
construction details associated with stormwater control and treatment measures otherwise known as Best
Management Practices (BMPs).
The CSU contract is in keeping with the City’s water quality policies and furthering staff’s efforts under the City’s
state permit to discharge stormwater into state waters. It is also in furtherance of the City’s policy under City Code
Section 26-493 (d) that states in part:
The Utilities Executive Director is also authorized to require sampling for such pollutant parameters
according to such schedule as the Utilities Executive Director determines to be appropriate to
ascertain water quality. Any such requirements added by the Utilities Executive Director shall be
reported together with those required by the CDPS to both the Utilities Executive Director and the
CDPS.
Agenda Item 8
Item # 8 Page 2
The use of CSU research services is critical in order to maintain the continuity and the consistency of the
studies. CSU has been the City’s research partner in the field of stormwater quality since 2008 and has
consistently provided high quality services on a recurring basis. Using a different contractor at this point would
significantly increase the costs of the requested services due to a lack of familiarity with the services
requested.
CSU staff is uniquely qualified to provide the requested services due to the academic quality of the needed
research and to CSU’s ability to draw on specialized experts in the field of water engineering. Additionally,
long standing relationships have been developed between City and CSU staff in this area. Staff recommends
entering into another Intergovernmental Agreement with CSU without engaging in competitive bidding.
CITY FINANCIAL IMPACTS
The funds needed with these services have been appropriated by the City as part of the funds set aside for
stormwater quality consulting services.

Summary of requested CSU research services
Bioretention Cell Monitoring Program
In Spring 2012, the City constructed a bioretention stormwater treatment cell (a LID-type water
quality treatment facility) 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 those research projects results to semi‐arid environments
such as Colorado is unknown. Given the City’s requirement for installing LID‐type stormwater
facilities for future development, it is important to understand how these facilities will operate
in Fort Collins’ climate.
CSU has previously monitored this bioretention cell performance during the summers of 2013
and 2014. Prior to the 2014 sampling season, the bioretention cell underdrain system was
retrofitted to evaluate how performance is affected by the underdrain design. Results of the
modified design showed significantly higher performance in terms of runoff and pollutant
reduction. CSU recommends that the bioretention cell be monitored for at least one more season
to collect a sufficient number of data points to improve confidence in the results.
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 2016 monitoring season (approximately
May 1‐September 30). Stormwater samples will be submitted to a local laboratory and analyzed
for total suspended solids and nutrients (nitrogen/phosphorus). 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. Results of the 2016 monitoring will be documented in a technical memorandum.
Winter Runoff Study
The following objectives reflect both the original (2010-2011) study objectives and current study
objectives.
The scope of the monitoring program is to evaluate the impacts of roadway deicing operations
(RDO) on the water quality of Spring Creek and the impacts to urban stream water quality. The
primary objectives are to:
1) Evaluate the effects of deicing materials on urban stream quality in terms of chloride
concentrations and its potential impacts on aquatic life
2) Determine if RDO is a significant source of chloride in the Spring Creek watershed
ATTACHMENT 2
3) Collect additional water quality samples to improve chloride concentration modeling
techniques (specific-conductance) in Spring Creek (new for 2012 study)
4) Collect additional data to improve stream flow estimates (new for 2012 study)
Although deicing materials contain many different constituents, the scope of this study was and
will continue to be limited to determining concentrations of chloride in the stream as a result of
roadway deicing operations. Chloride exists in high concentrations in most deicing materials.
Instream chloride concentrations were estimated throughout the monitoring period at four
different sites located in Spring Creek.
The following is a summary of conclusions and recommendations after the 2012 study was
completed:
The key finding of the study is that chloride concentrations in Spring Creek continue to
be found below established water quality standards for aquatic life in all but a few
instances.
RDO is the most significant source of chloride loading to the lower reaches of Spring
Creek, however in the upper reaches of the watershed (above Drake Road) non-RDO
chloride sources (private use of deicing materials) may contribute 20-60% of the total
chloride load applied.
The City Streets Department (Streets) is responsible for keeping major roadways safe and
passable, including during winter months when snow and ice hamper travel in roadways. In order
to do so, the Streets Department uses various deicing materials (e.g. salt, Apex liquid deicer, etc.)
to melt snow and ice so that it runs off of travel lanes. Ultimately, the melted snow/ice and the
deicing materials end up in local rivers and streams where the “chemicals” from deicing
materials may have detrimental impacts on aquatic life.
The primary objective of this research activity is to assess the potential impact of deicing
material applications on aquatic life in Spring Creek. Specifically, chloride concentrations in
Spring Creek will be compared to water quality metrics that are known to effect aquatic life.
A secondary objective is to estimate the amount of applied deicing material that can result in
chloride concentrations exceeding water quality metrics. To accomplish these objectives, CSU
will perform the following tasks:
• Install four water quality sondes at strategic locations within Spring Creek to
continuously monitoring specific conductance and water depth.
• During deicing/runoff events, collect water quality grab samples in Spring Creek and
analyze the samples for chloride
• Using specific conductance/chloride relationship, generate continuous record of chloride
concentrations within Spring Creek.
• Compare the magnitude and duration of chloride concentrations against criteria
established for aquatic health.
• Obtain deicing material application data from Streets and calculate the total amount of
deicing material applied during each event. Compare amounts against in‐stream chloride
concentrations.
• All of the above activities will take place from approximately February 1, 2016 toMay 1,
2016.
Based on these findings, deicing material reduction strategies that the City employs are focused
on RDO operations and less on private use of deicing materials. To date, the City has not chosen
to pursue any formal citizen awareness and education strategy to reduce the impacts of non-RDO
chloride sources. Any efforts made in this vein should focus on the upper reaches of Spring
Creek where it appears impacts from non-RDO sources are significant enough to be quantified
using the monitoring protocols developed for the study.
The results of this task will be documented in a technical memorandum.
Nutrient Sources in Urban Stormwater
The discharge of nutrients (i.e. nitrogen and phosphorus) to receiving waters is a significant
problem in Colorado and elsewhere in the U.S. Recently, the Colorado Department of Public
Health and Environment (CDPHE) has promulgated new rules to limit the discharge of nutrients
from the urban environment. In terms of urban stormwater discharges, the new rules require
targeted education and outreach campaigns to address sources that contribute to nutrient
discharges.
To conduct a targeted education and outreach campaign, the regulated community (i.e. City)
must first know what the primary sources of urban stormwater nutrient discharges are. Potential
sources of nutrients in urban stormwater include lawn fertilizers, erosion of native soils,
atmospheric deposition, etc. However, the City does not currently have a good understanding of
all of the potential sources that may contribute to urban stormwater nutrient discharges.
The objective of this research activity is to identify potential sources of nutrients, and their
relative magnitude, in urban stormwater through a review of existing studies. To complete this
work, a thorough search will be conducted to identify peer‐reviewed studies that have identified,
quantified, or otherwise evaluated sources of nutrients in the urban environment. The results of
those studies will be summarized and documented in a report submitted to the City.
Best Management Practices (BMP) Construction Details
The City is interested in updating its standard Best Management Practices (BMPs) construction
details to include ultra‐urban stormwater BMPs and to modify existing details. At this time, the
City is waiting on the completion of a similar effort being conducted by the City/County of
Denver and Urban Drainage Flood Control District before it begins its own BMP construction
detail updates. Once the Denver/UDFCD effort is completed, the City expects to contract with
CSU to review the BMP construction details of Denver, UDFCD and other cities (e.g. Portland,
New York) and provide modifications to address Fort Collins‐specific stormwater criteria. This
work would be funded as an addendum to this scope of work, and the addendum will include a
more details scope of work for this activity.
Technical Supervision
This research will be conducted under the primary supervision of Chris Olson, P.E. Chris is a
Research Associate III at CSU working under Dr. Sybil Sharvelle. Chris has been managing
stormwater research for the City for the past 8 years.

RE: Policy rationale for City-CSU contract renewal and Sole Source
Exemption
PURCHASE AMOUNT $ 65,840
Background
The CSU contract is in keeping with the City’s water quality policies and furthering our efforts
under the City’s State permit to discharge stormwater into State waters.
It is also in furtherance of the City’s policy under section 26-493 (d) of the Municipal Code of
Fort Collins which partially states:
The Utilities Executive Director is also authorized to require sampling for such pollutant
parameters according to such schedule as the Utilities Executive Director determines to be
appropriate to ascertain water quality. Any such requirements added by the Utilities Executive
Director shall be reported together with those required by the CDPS to both the Utilities
Executive Director and the CDPS.
The deicing study was requested by Council of staff since 2005 and the City has provided a
yearly sampling study of Spring Creek in order to ascertain the level of pollutants in receiving
waters as a result of winter deicing activities and in order to develop policies that will result in
minimal discharge of pollutants into State Waters.
Exception to Competitive Bidding Rationale:
Since CSU is our research partner and has provided this work on a recurring basis since 2008,
using a different contractor will significantly increase the cost of the contract due to their lack of
familiarity with the services requested
ATTACHMENT 4
Additionally Colorado State University is a local partner to the City of Fort Collins and staff has
been directed by Council to work with this world renowned institution in the field of water quality
research and treatment whenever possible.
Finally due to its ability to draw on experts in the field of water engineering CSU is a unique
position in the community to provide the scope of services requested.
