SUBJECT
First Reading of Ordinance No. 057, 2004, Amending Chapter 26 of the City Code to Reflect the
Adoption of Updated Master e A ' e Official Repository of Plan
Documents.
RECOMMENDATION
Staff recommends adoption of the Ordinance on First Reading. The Water Board, Natural
Resources Advisory Board and the Planning and Zoning Board recommend adoption of the
Ordinance.
FINANCIAL IMPACT T
Staff believes the recommen $13Vion ' C funded od control projects is achievable
under the current funding plan m ppr years. �s funding plan calls for 6 percent
increases in rates for each of the next four years,then level for the next twenty years. City Council
sets stormwater rates as a part of the budget process, which in turn determines the length of time
required to build out the master plans.
EXECUTIVE SUMMARY
The Ordinance updates curre ity o re nc t as drainage plans for the various
basins in the city by re in nd ree ting on 43(a). A number of the master
drainage plans have been upd do d s' e e related de language was modified. This
is in part due to the fact that in 1 , e Ci ounce adopted a igher rainfall standard based upon
a technical analysis of rainfall statistics, which resulted in modifications to the master plans. In
addition, updated topographic information, changes in conditions, and better technical data and
methods has resulted in other improvements from the previously listed plans. Staff has prepared a
Stormwater Master Plan Executive Summary Report that summarizes citywide information and
presents brief summaries of the master plan for each basin. The summarized basin master plans
strive to design projects that provide cost-effective flood protection for a 100-year rainfall event.
The basin master plans recommend a number of flood control and other types of improvements.
In addition, the Ordinance modifies City Code Section 26-543(b), so as to provide that the master
drainage plans and updates to those plans will be maintained on file in the office of the Utilities,
April 6, 2004 -2- Item No. 16
rather than the office of the City Clerk. This change is to improve the efficiency and effectiveness
of the use and maintenance of those records.
BACKGROUND
The Master Plan Executive Summary takes a detailed look at the flooding and water quality
problems in each basin and provides the general direction for stormwater management in those
basins. The stormwater basin master plans include:
1. Recommende Croje homes and businesses, the
potential for 1 JatPasinY,
froads,
2. guidance for ne
3. guidance for enhancements to the riparian habitat along stream corridors to improve
water quality, and
4. guidance for stabilizing streams where necessary.
The stormwater master plans strive to design projects that provide cost-effective flood protection
for a 100-year rainfall event.
The Master Plan Executive summary outlines plan-recommended projects to solve existing flooding
problems on both structures a n t u P56%�s, lects do reduce the floodplain
on undeveloped land inadve ntly. is us s the problem is downstream of
undeveloped land and the solu is u s am. on developed land does not constitute
a public problem, reduction of odp upe is not a goal of the master plan.
New development in a floodplain is required to adhere to the floodplain regulations.
In 1999, Council adopted a higher rainfall standard based upon a technical analysis of rainfall
statistics. Higher rainfall resulted in higher runoff and larger floodplains. This required an update
to all master plans to reflect the higher rainfall and reevaluate the needed capital improvements.
In 2001, Council adopted a revised Canal Importation Basin Master Plan.
In 2001, Council approved a to 12 '1 n i st ter improvements over the next
25 years on a pay-as-you-go sis. thly s typi residential customer in 2004 are
$14.26. By 2008, monthly fe r t t 'ca si ntial oust er will be $18.35. Monthly fees
will return to maintenance levels in approximately 25 years. New development pays a storm
drainage impact fee. Revision to the impact fee will be brought to Council after adoption of the new
master plan.
Colorado and Federal laws require the city to regulate to the 100-year storm event. This means the
100-year storm is used to map the regulatory floodplain and enforce floodplain regulations. The
City,through Storm Drainage Design Criteria and Construction Standards,also requires developers
to use the 100-year storm for the design of new drainage facilities. Current City policy is master
plans should recommend improvements that provide 100-year protection when the benefits of
projects outweigh their costs. In 2001 Council requested staff to include in future master planning
efforts an analysis of providing flood protection for events less severe than the 100-year flood event.
April 6, 2004 -3- Item No. 16
Existing Conditions Damage Statistics
All basins have been analyzed based on the higher rainfall, resulting in higher runoff flows, and
deeper and wider floodplains. The studies show significant flooding problems in a variety of
locations around the city with the following results:
1. damage could occur to more than 2,600 structures during a 100-year storm,
2. the estimated damage from a single 100-year storm would be approximately$142 million,
and
3. if nothing is done to th is n s eYdges over the next 50-years are
estimated to beover$ 3 millThe 2003 Stormwater Master m�xe e S mar
In general, the recommended projects include construction or enlargement of detention ponds,
construction of open channels and storm sewers,and enlargement of road culverts. Because master
plans are conceptual in nature,the projects proposed may change based upon actual field conditions
at the time of final design. The attached Stormwater Master Plan Executive Summary Report
(September 2003)provides an overview of the technical process and recommendations of the master
plans from all basins. The first several pages contain a summary of citywide information. This is
followed by one or two page su 'es ach Yba5jamaster plans strive to design
projects that provide cost-effe e fl ote n rinfall event. The master plans
recommend:
1. $164 million in flood control projects, $132 million in the City and$32 million funded by
the County and others,
2. $42 million in projects funded by partners (development,grants,etc.)as opportunities arise
for water quality enhancements, and localized drainage improvements,
3. standardized development criteria to reduce peak flow leaving newly developed sites to 2-
years historic or equivalent (many basins already had this requirement),
4. regional water quality treatment opportunities to improve the quality of stormwater runoff
and,
5. expanded wetlands anC
e p ' n or, sties along natural channels to
improve the quality of runoOverall, the basin master pla o na he maj of structural damages caused by
flooding in the city. Staff estimates flood damage will be eliminated on approximately 2,200
structures,almost 85%of the total number of damaged structures. The following table summarizes
the benefits of the recommended master plans.
April 6, 2004 -4- Item No. 16
Benefit of$164 Million in Flood Control Projects
Before I After
Property Damage Over the
Next 50-Years $353 million $63 million
Number of Structures
Damaged by 100-Year Storm 2,600 400
In addition to the above tangible benefits of reduced damages to structures,the following intangible
benefits are not included in the estimates:
1. reduced damages to v icles an(),Pture,
2. reduced emergency res se housing costs,
3. streets are open during flooding events for emergency response vehicles,
4. improved water quality, environmental enhancement, and providing a feeling of safety and
security for citizens, and
5. reduced risk of injury and/or loss of life.
To the extent possible, the proposed flood control projects provide opportunities to enhance and
expand wetlands and natural habitat areas to improve the quality of storm runoff. Recommendations
to retain and improve existing riparian habitat along the natural channels are also included.
Staff believes the completion $132 rl lion i C de d control projects is achievable
ima under the approved funding p in ap years.
The proposed Boxelder/Cooper Slough Master Plan currently recommends improvements in
Boxelder/Cooper Slough basin to solve flood damage problems in the Mulberry/1-25 area.
However, this basin does have a large amount of undeveloped land in the floodplain as well as a
large amount of land in the Mountain Vista Subarea that does not have an adequate drainage outfall.
Additional study by both the City and the County has begun in order to determine development
guidance and identify possible solutions to stormwater issues in these areas. Staff will return to
Council with the results of this additional study if necessary.
Reduced Level of Protection al )InOCoPil
The recommended plan of i rove n pr iding a 100-year level of flood
protection whenever it is cost effec ve. ske s aff to look at the costs and benefits
of providing a reduced level of protection in future master planning efforts. Staff looked at a 50-
year level of protection for this analysis. Under this scenario, the regulatory floodplain is still
mapped using the 100-year storm and property and structures remaining in the floodplain after
projects are built are subject to flood damages and floodplain regulations.
April 6, 2004 -5- Item No. 16
The following table shows the costs and benefits of the 50-year level of protection plan and provides
a comparison with the recommended 100-year level-of-protection plan.
Reduced Level of Protection Analysis
100-Year Level of 50-Year Level of
Protection Protection
Cost of Flood Control
Projects $ 164 million $ 141 million
Property Damage
Reduced $290 million $ 146 million
Number of Stru
Damages ElimilSted 11 200 5
Although the cost of the 10 la ' ' e favors benefit to cost ratio shows the
effectiveness of the plan. Compared to the lower level of protection plan,an additional$20 million
in projects will result in$144 million in damage reduction on 700 structures. This extra investment
also represents a significant reduction in risk to the citizens.
At the January 13, 2004 Study Session, City Council supported the 100-year level of protection.
Public Outreach
The process of informing prop e r basins of upcoming changes
to both the master plans and odplai gula n e i y 2002 and continued until late
2003. A variety of communic 'on tool uch u omer mai gs, web pages,press releases and
media interviews, public meets d ou and ou ch to both internal and external
groups potentially affected were used.
In 2002,customers most affected by floodplain boundaries and proposed regulations were identified
as the primary focus of initial outreach. Because a significant number of those within the mapped
floodplains are Larimer County residents, City and County staff collaborated on public outreach.
Eight public open houses were held to provide an opportunity for customers and staff to discuss the
information included in the mailin s as well as the master lannin process. Customers received
mailed invitations and open ho es w ve d VUes
s Coloradoan and North Forty
News. At the same time,web ges we devel e eWeb site to provide additional
information. Over 4,000 pac s we ail e n 250 peop attended the 8 open houses held
during the year.
In 2003, public outreach was expanded to include all property owners and renters in the City's
stormwater drainage basins,not just those within the mapped floodplains. At a kickoff open house
held in February, property owners and renters were invited to learn more about the City's
stormwater drainage basins, floodplains and regulations, safety and flood protections, and the
regional weather patterns that can result in flash flooding.
April 6, 2004 -6- Item No. 16
Following the kickoff,nine additional public open houses were held. Information presented at the
open houses consisted of basin-specific information as well as information about the citywide
planning process, including:
1. flooding histories for each basin,
2. maps showing identified basin problems,
3. maps showing proposed solutions,
4. proposed floodplain regulations,
5. stormwater project fundin , and
6. the process for adoptio f m Ian ' g n lai regulations.
Over 62,000 pieces of mail ere inc i informa nal packets, basin-wide kickoff
invitations, open house invitatio and le s to commum y organizations. Publicity for the
outreach campaign included media releases and briefings, and advertising in local media.
The nine open houses were attended by 470 people. Of the 24 community organizations contacted,
seven asked for presentations or more information. Presentations were made to six City Boards,
including the Water Board,the Natural Resources Advisory Board,the Planning and Zoning Board,
the Affordable Housing Board, Landmark Preservation Board and Parks and Recreation Board.
Comment forms were availabl o u e lilies Web site. Thirty-three
comment forms were submit A gh st f s attended open houses did not
comment formally on either t propos mast p r floo lain regulations, almost everyone
got a chance to express their v t
Comments received on master plan issues can generally be summarized as follows:
1. support for specific projects, build as soon as possible,
2. support for master planning as a whole, it seems reasonable,
3. questions about local drainage issues,
4. make sure water quality is an integral part of capital projects,
5. concern projects don't encourage mos uitoes,
6. support for the 100-yeCns
f ote n
7. do more to protect citi8. implementation of theI is a ensive, ding is rare,
9. balance habitat protection with recreational users,
10. keep streams natural, not structural,
11. questions about impact of recent nearby development,
12. concern that projects remove vacant land from the floodplain, which allows development,
and
13. would like to see funding changed back to basin by basin,floodplain properties should pay
more.
In March of 2004, about 10,000 post cards were mailed to customers who live or have property in
floodplains, informing them that the updated basin master plans would be considered by City
Council on April 6.
