Mitigation plan information 
 
Proposed activity description (optional) 
The Maricopa County Multi-Jurisdictional 
Hazard Mitigation Plan includes a study of each 
specific jurisdiction, including Buckeye, in 
Maricopa County, and all potential hazards. The 
infrastructure that is the subject of this 
proposed activity is also a result of a flooding 
study conducted by the Flood Control District of 
Maricopa County (FCDMC) and is located in or 
adjacent to the federally designated flood zone, 
with a chance of annual flooding. The activity 
will place a storm drainpipe and catch basins in 
Monroe Avenue from Miller Road to 9th Street. 
The system will relieve the issue of flooding for 
the 10-year, 2-hour storm for Downtown 
Buckeye. The stormwater will be conveyed in a 
storm drainpipe system under Sixth Street to 
South Street. At South Street, the pipe system 
will travel east to Seventh Street and outfall into 
a retention basin. From there, the stormwater 
will be channeled through a nature-based 
irrigation canal system leading to the Gila River. 
The Maricopa County Multi-Jurisdictional 
Hazard Mitigation Plan refers to stormwater 
flood mitigation on pages 297, 302-304, 422-
425, and specifically to Buckeye on page 431, 
Table 6-8-2, ID No. 5.

This proposal will benefit the residents and businesses in the Downtown area of 
the City of Buckeye and reduce the occurrence of flooding. The Federal 
Administration priorities being addressed by this project include, but are not 
limited to, rebuilding critical infrastructure to compensate for decades of public

disinvestment; environmental stewardship; and building community resilience 
and safety.   
This area was initially developed during a time when open irrigation ditches and 
farm fields protected against excess stormwater runoff. With many of those 
fields gone and some irrigation ditches covered, annually recurring flooding has 
become a problem in the historic Buckeye downtown area. Stormwater in this 
area generally flows south to southeast towards the Gila River. Many of the 
homes in the area are at a level below the street crown and experience flooding 
in their homes on a regular basis. In 2014, downtown Buckeye experienced a 
100-year storm and flooding.  And the most recent such event occurred on 
October 16, 2022. The area to benefit from stormwater-flood mitigation has a 
population of 7,402, 68% of whom are minorities (Arizona Demographics, 
Maricopa Association of Governments). Also, approximately 25% of the people 
have income below the poverty level, 39% with income below 150% of the 
poverty level, and almost 48% with income below 200% of the poverty level 
(Arizona Demographics, Maricopa Association of Governments). 
In June 2004, Project Engineering Consultants, Ltd. (PEC), in coordination with 
the Flood Control District of Maricopa County (FCDMC), met with Buckeye City 
staff, made several site visits, and reviewed the provided utility documentation 
during the course of the study. PEC Engineers also met with the management of 
the Buckeye Irrigation District and the Arlington Canal Company to determine 
the feasibility of using their facilities as a discharge location. PEC also attended 
a public meeting held in the Buckeye Community Center with the Flood Control 
District of Maricopa County (FCDMC). PEC surveyed a portion of the area to 
obtain additional data. PEC concluded that it is reasonable to construct a basin 
to contain the 100-year stormwater runoff with a 10-year collection system. PEC 
recommended the development of a major storm drain system along Monroe 
Avenue, a multi-use detention basin, and an outfall corridor to discharge the 
storm water into existing irrigation district facilities leading to the Gila River. As 
the City continues to grow and develop, this proposed drainage system in the 
downtown area will become increasingly important in minimizing the impact of 
future storm events in the City of Buckeye.  The most recent major flooding 
event occurred on 10-16-22. 
In November 2004, the FCDMC released the results of an Area Drainage Master 
Study (ADMS) to identify known and potential flooding and erosion hazards in 
the Buckeye area.  The study researched all known flooding hazards in the 
project area through verbal and written contact with various municipal, county, 
and state agencies, as well as citizens in the area for any information or photos 
relevant to known flooding issues.  After analyzing the data, it was determined 
that the majority of existing flooding problems were located within historic 
downtown Buckeye.     
The downtown Buckeye area currently experiences drainage deficiencies during 
relatively small storm events. Many downtown streets have no curb and gutter 
or drainage facilities. Historically, development occurred in the downtown area 
without current provisions.  For on-site stormwater retention facilities, most 
developed parcels in the downtown area do not have sufficient area to retrofit

Scope of work 
 
retention basins. Several locations experience ponded water and poor drainage 
after storm events. Many buildings in the downtown area have low finish floor 
elevations—some with less than 6 inches of elevation difference from the 
nearest roadway elevation. 
According to the Transportation Disadvantaged Census Tracts, the area of the 
Buckeye Downtown Storm Water Flood Mitigation Project has six disadvantaged 
indicators.  These indicators are the historically disadvantaged community 
indicator, transportation disadvantaged indicator, health disadvantaged 
indicator, economy disadvantaged indicator, equity disadvantaged indicator, 
and environmental disadvantaged indicator. 
According to the EPA EJScreen for environmental justice rating, this area ranks 
in the 90th to 100th percentile for RMP facility proximity, wastewater discharge, 
flood risk, less than a high school education, low income, socioeconomics 
indicator, and unemployment rate.  The area also ranks in the 80th to 90th 
percentile for people of color and low life expectancy.  Proximity to RMP facilities 
is calculated at the census tract level using a spatial enumeration methodology 
developed by the EPA.  Numerous studies have found socially disadvantaged 
groups, such as minorities and low-income individuals, who reside near facilities 
where accidental releases of extremely hazardous substances are likely to 
occur, to be disproportionately distributed with respect to various health 
hazards and pollution sources. 
The subject community has a CDC SVI score of 0.7645, which indicates a high 
level of vulnerability to negative effects caused by external stresses on human 
health, such as natural or human-caused disasters or disease outbreaks. By 
installing a storm water mitigation drainage system and diverting storm water 
away from humans and property, and into nature-based waterways such as 
open canals and rivers, Buckeye will avert recurring property damage and 
enhance public safety in the future, and relieve the related external stresses on 
human health. Nature-based solutions (NbS) are actions that protect, 
sustainably manage, or restore natural ecosystems, that address societal 
challenges such as climate change, human health, food and water security, and 
disaster risk reduction effectively and adaptively, simultaneously providing 
human well-being and biodiversity benefits.

The project is located in the City of Buckeye, located in Maricopa County, 
Arizona. Buckeye is a rural area with population clusters spread over 640 sq. 
miles, covered by greater than 90% agricultural/open space, 2% 
industrial/commercial use, and 4% residential. Buckeye is located 40 miles 
west of Phoenix and consists of 640 square miles. Buckeye is home to 
approximately 114,000 people. 100% of the downtown population of about 
31,000 resides in the proposed project’s benefiting area. Median household 
income is estimated at $57,000. There are about 30 businesses in the 
impacted/benefitted area. Buckeye’s 2024 main ethnic breakdown is 35% 
Latino, 48% White, 8% Black and 9% other. The World Population Review 
estimates the median household income for 2024 is $94,188, the median age 
is 35 years, and 8% of households are below the poverty level. Portions of 
Buckeye, including the benefitted area, have been federally identified as 
historically disadvantaged as to transportation, health, equity, environmental 
indicators, Risk Management Plan (RMP) facility proximity, wastewater 
discharge, flood risk, education, income, socioeconomic indicators, 
unemployment, and high level of vulnerability to negative effects caused by 
external stresses on human health. This includes the affected area of this 
project. 
The total population affected is 27% (31,000 / 114,000 = 0.2719 (27.19%)).

description of 
your proposed 
activity 
In November 2004, the FCDMC released the results of an Area Drainage Master 
Study (ADMS) to identify known and potential flooding and erosion hazards in 
the Buckeye area. The study researched all known flooding hazards in the 
project area through verbal and written contact with various municipal, county, 
and state agencies, as well as citizens in the area for any information or photos 
relevant to known flooding issues.  After analyzing the data, it was determined 
that the majority of existing flooding problems were located within historic 
downtown Buckeye.     
The downtown Buckeye area currently experiences drainage deficiencies during 
relatively small storm events. Many downtown streets have no curb and gutter 
or drainage facilities. Historically, development occurred in the downtown area 
without current provisions.  For on-site stormwater retention facilities, most 
developed parcels in the downtown area do not have sufficient area to retrofit 
retention basins. Several locations experience ponded water and poor drainage 
after storm events. Many buildings in the downtown area have low finish floor 
elevations—some with less than 6 inches of elevation difference from the 
nearest roadway elevation. 
 
In 2010, Dibble Engineering (DE) was engaged to develop a stormwater flood 
mitigation plan for the Buckeye downtown area. As a result, DE prepared a 
detailed stormwater mitigation plan. Subsequently, a portion of this plan was 
constructed.  The remainder of the plan needs to be completed to mitigate 
recurring stormwater flooding within the downtown area of Buckeye. Contained 
within this grant request, 
 
During the creation of a county-wide hazard mitigation plan in 2021-2022 
(Maricopa County Multi-Jurisdictional Hazard Mitigation Plan), the following was 
determined. The occurrence of a 10-year flood in downtown Buckeye would 
create an estimated damage replacement value of non-residential property of 
$24,838,000, and an estimated residential damage replacement value of 
$97,749,000. The proposed design concept report for the Buckeye downtown 
flood mitigation was designed to mitigate a 10-year flood. 
This area is also designated as a 100-year FEMA floodway. Within this area, 
there are single-family residential, multi-family residential, commercial, a public 
elementary school, several daycare facilities, a fire station, and some 
healthcare facilities.  
The City of Buckeye Stormwater Flooding Mitigation Improvement Project is a 
project that will benefit the residents and businesses of the City of Buckeye and 
will reduce the occurrence of flooding problems. The Federal Administration 
priorities being addressed by this project include, but are not limited to, 
rebuilding critical infrastructure to compensate for decades of public 
disinvestment, environmental stewardship, and building community resilience 
and safety. 
Buckeye and FCDMC have recently renewed conversations and entered into an 
Intergovernmental Agreement (IGA) to address this needed flood mitigation 
project. In September 2025, Buckeye retained the services of Marc Taylor Inc to

Project Subapplication 
 
16 
provide a 100% construction document cost estimate for the Buckeye 
Downtown Stormwater Flood Mitigation Project.  
The activity will place a storm drainpipe and catch basins in Monroe Avenue 
from Miller Road to 9th Street, and the system will relieve the issue of flooding 
for the 10-year, 2-hour storm for Downtown Buckeye. The stormwater will be 
conveyed in a storm drainpipe system under Sixth Street to South Street. At 
South Street, the drainpipe system will travel east to Seventh Street and outfall 
into a retention basin. From there, the stormwater will be channeled through a 
nature-based irrigation canal system leading to the Gila River. 
Once completed, the stormwater drainage system will direct the floodwater into 
the drainage system, and the nature-based irrigation canals will direct the water 
to the Gila River and away from any structures, property, and streets. 
Stormwater flood mitigation would have a definite benefit to health and safety 
(preventing flooding of structures, mold, and dangerous flash flooding of streets 
& alleys). The goal of this mitigation project is to prevent loss of property and 
loss of life, while enhancing the quality of life within this historically 
disadvantaged community. It will also improve road safety along the impacted 
primary transportation corridors. 
Additional benefits of this project are related to environmental stewardship. The 
flood drainage system and the managed retention basin will reduce the quantity 
and velocity of the water discharge. This will reduce erosion and create 
improvements to the desert habitat by maintaining, enhancing, creating, and 
protecting the habitat from flood events. Other benefits will be enhancements 
and improvements to the groundwater and restoration of riparian areas through 
the management of the retention basin. During the dry seasons, the retention 
basin will have multi-uses such as a sports field, cultural activities, and 
conservation education.  
Community lifelines will be enhanced as well, due to this project. Flooded 
roadways tend to inhibit ground surface activities and roadway pathways. 
Emergency services response times and delivery, such as medical, police, and 
fire, are slowed down or blocked during and after storms due to flooding. 
Additional community lifelines that are affected during flooding events include 
food, water, shelter, power grids, and communications grids. This proposed 
project will mitigate the negative impacts of flooding on these critical lifelines. 
Also, during flooding events, hazardous materials can be disrupted and carried 
throughout the community by floodwaters, potentially exposing humans and 
creating negative health impacts. 
Resilience is the capacity of individuals, communities, businesses, institutions, 
and governments to adapt to changing conditions and to prepare for, withstand, 
and rapidly recover from disruptions to everyday life, such as natural hazard 
events and safety. The proposed Buckeye Downtown Stormwater Flood 
Mitigation project is in response to that call for a more resilient community. 
Once completed, the flood mitigation will divert flooding away from at-risk areas 
and towards access to natural waterways. This will reduce the risk of loss of life 
and property. It will enhance the physical, behavioral, social, and environmental 
health and well-being of an historically disadvantaged community and provide 
the greatest support to those with the greatest need. This project will enhance

Scope of work 
 
community resilience and provide greater ability to access emergency, medical, 
and social services before, during, and after natural hazardous events. 
The project supports the missions of the City of Buckeye, the United States 
Department of Homeland Security, the Flood Control District of Maricopa 
County, and various community-based non-profit groups. It also leverages 
collaborative efforts by the aforementioned groups and creates a force 
multiplier.

How will the 
mitigation 
activity be 
implemented? 
The City of Buckeye Historic Downtown Stormwater Flood Mitigation Project will 
complete improvements along Monroe Avenue to install the required 
stormwater collection drain system and tie into the infrastructure that was 
installed in 2011 along Monroe Avenue and 6th Street. The 2011 constructed 
portion of the storm drain from approximately Monroe Ave./6th Street to 
Clanton Ave./6th Street completed construction in 2011. This was done 
because the school expansion/plaza project that was under construction at that 
time had that area opened up, and Buckeye wanted to avoid any disturbance to 
the new plaza and school campus in the future after it was completed. As can 
be viewed in the below aerial, the 2011 construction is in the middle of the 
school property, underground. At the time of design of that project, 6th Street 
continued south from Monroe Ave with no discontinuous portions. The storm 
drainpipe was put in the ground and plugged at both the upstream and the 
downstream ends so that it is currently non-functional as a storm water 
collection/conveyance system. Additionally, at that time in 2011, Buckeye only 
had enough funding to complete that portion. Please see the below attached 
map for further details. The 2011 project did not independently solve a 
problem. It was completed at that time as a matter of available funding and to 
prevent any future demolition of existing infrastructure at the adjacent school 
project that was under construction in 2011. The proposed project which is the 
subject of this grant application requires tying into the existing infrastructure to 
solve the drainage issue.  
The new infrastructure improvement activity will place a storm drainpipe and 
catch basins in Monroe Avenue from Miller Road to 9th Street, and the system 
will relieve the issue of flooding for the 10-year, 2-hour storm for Downtown 
Buckeye. The stormwater will be conveyed in a storm drainpipe system under 
Sixth Street from Monroe Avenue to South Street. At South Street, the drainpipe 
system will travel east to Seventh Street and outfall into a retention basin. From 
there, the stormwater will be channeled through a nature-based irrigation canal 
system leading to the Gila River.

knowledge, and experience in successfully completing projects of this 
magnitude. The infrastructure and system as modified by this proposal will 
successfully divert stormwater flooding away from property and people, and 
towards the Gila River by way of nature-based canal systems. 
 
DESIGN CRITERIA 
Design criteria for this project is based on (1) standards developed as part of 
the City of Buckeye Downtown Drainage Improvements Alternatives Analysis 
Report, (2) the City of Buckeye Stormwater Drainage System Design Manual 
(DM500), and (3) the FCDMC Drainage Standards and Policies Manual (this 
manual makes reference to the Drainage Design Manual for Maricopa County 
Volume I (Hydrology 
 
Manual) and Volume II (Hydraulics Manual). Specific design criteria for various 
elements are provided in the following sections. 
 
A. Rainfall 
Site‐specific rainfall data has been developed for use in the drainage design for 
the contributing watershed areas. National Oceanic and Atmospheric 
Administration (NOAA) Atlas 2 values are used for this project. Atlas 2 is

Roadway Inundation 
• Allowable spread on Monroe Avenue is approximately 20 feet per half street 
during a 10‐ year, 6‐hour storm event. This provides for a single 12’ dry lane 
in each direction. This criterion will not apply to connecting side streets. 
• Roadway flow on Monroe Avenue is not to exceed the top of the curb or 6” 
above the gutter flow line for the 10‐year storm event. 
• A Manning's "n" value of 0.016 will be used for street flow on paved streets 
unless special conditions exist. 
 
C. 
Catch Basins 
• City of Buckeye Standard Detail B‐510A (curb opening catch basin) will be 
used for sump and on‐grade conditions within the roadway. Regardless of 
the calculated peak flow rate, no curb inlet type catch basin will be smaller 
than an M‐1, L=3’ basin constructed in accordance with the City of Buckeye 
Detail B‐510A. 
• MAG Standard Detail 535 will be used for any areas outside of the roadway 
where stormwater flows are anticipated. 
• The curb opening for catch basins is not greater than five inches in height. 
• Catch basins on continuous grade are not required to intercept 100% of the 
10‐year flow. 
  
D. 
Storm Drains 
• In cases where the peak flows from a 10‐year 6‐hour design storm exceed 
the roadway inundation requirements, underground pipes of sufficient size 
to carry the excess will be designed and installed. 
• A minimum pipe size of 18 inches will be used for lateral catch basin 
connector pipes. 
• A minimum pipe size of 24 inches will be used for main line pipes. 
• Storm drains with flow velocities less than 3 fps for 0.5xQ Design or in 
excess of 15 fps for Q Design will require approval. 
• Clearance with water and sewer facilities requires a minimum of 4 feet 
horizontally and 1 foot vertically unless otherwise approved by the City of 
Buckeye. Clearance with other utilities to be a minimum of 1 foot both 
horizontally and vertically.

Project Subapplication 
 
22 
• HGL will be greater than or equal to 1 foot below the grate/inlet elevation of 
all catch basins. 
• EGL will be below the adjacent gutter flow line elevation.

Retention Basins 
• Maximum water depth of the basin is 7.0 feet. 
• Approximately 5‐foot clearance will be provided between the expected 
groundwater elevations and the basin bottom. 
• Total volume required is the 10‐year, 6‐hour design storm runoff volume. 
• A 1‐foot minimum freeboard is required. 
• A 16’ wide access ramp will be provided for maintenance.

• Trash racks are required on outlet pipes greater than 24” in diameter. 
• First flush volume will be retained within the basin. 
 
METHODOLOGY & APPROACH 
 
F. 
Survey & Mapping 
Dibble Engineering provided a topographic survey for the project limits. The 
initial survey was conducted in August of 2009. An additional collection was 
performed in March of 2010. The survey was conducted under the direction of 
Randy Bilyeu, R.L.S. The data for survey and mapping is NAD83 and NAVD 
1988. 
 
Mapping was prepared for the FCDMC by Kenney Aerial Mapping, Inc, under a 
separate contract, in preparation for the Buckeye ADMS. This 2‐foot contour 
data was used for the Buckeye ADMP. More recent aerial photography was 
flown in December 2008. The 2‐foot mapping, along with new aerial 
photography prepared by the FCDMC, is used for this project. 
 
G. 
Hydrology 
The existing hydrology HEC‐1 proposed condition model of the area was 
developed as part of the Downtown Storm Drain Alternatives Analysis Report. 
This model is used to size the storm drain system. Watershed boundaries, 
Subbasin limits, and flow paths are determined by field reconnaissance, 2-foot 
contour mapping, existing drainage reports, project survey, and aerial 
  
photography. During the initial design during the Alternatives Analysis Report, it 
was determined that the north‐south corridor for the storm drain system needs 
to be shifted from 7th Street to 6th Street, to avoid several critical utilities 
occupying the 7th Street corridor. The proposed condition HEC‐ 1 model has

Project Subapplication 
 
23 
been updated to reflect this change. The Existing Condition HEC‐1 Schematic is 
provided as Figure 3 in the attached Appendix C. The Proposed Condition HEC‐1 
Schematic is provided as Figure 4, attached. 
 
1. 
Parameter Estimation 
The following HEC‐1 modeling parameters and options are selected for this 
project: 
 
a. 
Unit Hydrographs 
S‐Graph method is used for this project. Sub‐basin area, flow path, flow length 
to sub‐basin centroid, upstream ground elevation, downstream ground 
elevation, and time‐area relation are provided to DDMSW for each sub‐basin. 
 
b. 
Aerial Reduction Factors – Per Table 2.2 of the FCDMC Hydrology Manual. 
 
c. 
Rainfall Losses 
Green & Ampt method has been selected for this project. The rainfall loss 
parameters are developed using guidance provided in the Hydrology Manual. 
The Green & Ampt infiltration equation parameters are based on logarithmic 
area‐averaging of the map unit hydraulic conductivities (XKSAT) for mapped 
soils in each basin, and the selection of capillary suction (PSIF) and soil 
moisture deficit (DTHETA) are based on the calculated sub‐basin value of 
XKSAT. The bare ground XKSAT values for each Sub‐basin are then adjusted for 
vegetation cover. The calculation of these parameters is accomplished within 
DDMSW. 
 
d. 
Flow Routing – Normal depth routing is used in this model. 
 
e. 
Computation Interval – 2 minutes. 
 
f. 
Land Use 
Figure 5 ‐ Existing Land Use is provided in the attached Appendix C. Beginning 
with the MAG 2005 land use, the existing conditions land use has been 
updated based on 2008 aerial photography provided by FCDMC. The land use 
was modified again after receiving instructions from the City to update the land 
use according to the 2008 zoning. For example, while some areas are currently 
residential, if they are zoned as commercial, the land use is modified to reflect 
commercial use. Land use defaults are provided by the FCDMC. 
 
g. 
Soils 
Soils information for the Green & Ampt method is obtained from a soil survey 
performed by the Soil Conservation Service (SCS).  Figure 6 ‐ Soils are provided

in Appendix C, attached. 
 H. Storm Drain Design 
Pavement and inlet hydraulic calculations are based on procedures contained 
in the Federal Highway Administration Hydraulic Engineering Circular No. 12 
Drainage of Highway Pavements, 1996, and are performed within Hydraflow 
Storm Sewers 2009, version 6.066 (Hydraflow) design software. 
  
1. 
Pipe Sizing 
The storm drain pipe system is sized for a 10‐year storm with 100% inlet 
interception in Hydraflow computer software. Within Hydraflow, catch basin flow 
rates are automatically summed where connector pipes meet the mainline pipe. 
These summed values are manually “corrected” at the mainline to match HEC‐1 
concentration point values. Storm drain hydraulic grade line calculations are 
performed by Hydraflow, and are made using an iterative procedure that applies 
Bernoulli’s energy equation between downstream and upstream ends of each 
line in the system. Manning’s equation is used to determine head losses due to 
pipe friction. Hydraflow estimates junction and manhole losses by multiplying a 
loss coefficient K times the velocity head. The values of K are input manually 
into Hydraflow and are based on criteria adapted from FHWA Hydraulic 
Engineering Circular No. 22 Urban Drainage Design Manual 2001 and the 
FCDMC Hydraulics Manual. Hydraflow is a 1‐dimensional flow model. 
 
2. 
Inlet Sizing 
Inlets are sized within the Hydraflow computer software to meet spread 
requirements on Monroe Avenue. Generally, 80% interception efficiency is 
pursued for maximum cost-to-benefit ratio. However, for this project, where the 
existing pavement has very little longitudinal slope and is prone to shallow 
ponding, a higher percentage of interception is desired. Where possible, 100% 
interception is the design goal. Inlet lengths in Hydraflow have been adjusted to 
account for an 80% clogging factor for curb opening inlets and 50% clogging 
factor for grates outside of roadways.

B. 10‐Year Storm Drain 
The proposed 10‐year storm drain system can be seen in Figure 9. Detailed 
Hydraflow software reports can be found in 
the attached Appendix E. Catch basin numbers on Figure 9, and the 
construction plans correspond to the onsite area numbers shown on 
Figure 8 in Appendix E.  The computed 10‐Year HGL exceeds an elevation of 1 
foot below the proposed adjacent grate/inlet elevation at two locations: catch 
basins #3 and #4. This occurs at lateral pipes where off-site flow is collected 
and input into an existing system. The existing 
system does not have the capacity to convey the anticipated flows. Downstream 
catch basins #1 and #5 have been upsized with 10-foot and 17-foot wings to 
account for flow‐by from 2nd street. Input flows at catch basins #3 and #4 have 
been reduced to their pipe capacities; the remainder of the flow is input at the 
next downstream catch basins. There are several off-site inlet locations, north of 
Monroe Avenue, where curb flow depth exceeds 6 inches, and inlets do not 
achieve 100% interception. Flows not captured in the offsite inlets upstream of 
Monroe Avenue are captured in inlets on Monroe Avenue for the design storm. 
All inlets on Monroe Avenue meet the design criteria established for the design

storm. 
 
C. 10‐Year Retention Basin 
The 10‐year, 6‐hour watershed runoff volume generated is 24 acre‐ft. The 
provided volume is 29 acre‐ft with an additional 1’ of freeboard. The basin is 
currently designed to drain in 33.6 hours using a 24‐inch outfall pipe with a 15‐
inch perforated pipe with rock barriers; this calculation assumes ½ the tested 
soil infiltration rate. This pipe empties to an existing irrigation ditch on 7th 
Street (aka Norton Street). Basin drain time calculations are provided in the 
attached Appendix G. 
 
The City of Buckeye drainage design guidelines call for all storm water within a 
given development to retain a minimum of the 100‐year, 2‐hour retention 
volume; however, since the project location is in close proximity to the Gila 
River, the proposed retention basin will retain the 10‐year, 6‐hour flows and 
provide for the first flush volume to be retained within the basin site. The first 
flush volume, i.e., the first 0.5‐inch of runoff volume, from the upstream 
watershed is 9 acre‐ft. This volume equates to approximately 2.75 ft of standing 
water in the basin. Dibble has obtained the geotechnical infiltration rates for the 
basin site that were used to determine if the basin can be drained from the site 
within 36‐hours. A geotechnical report prepared by Speedie and Associates on 
June 30, 2010, indicates that a percolation rate of 0.18 ft3/hour/ft2 was 
obtained in the vicinity of the basin. 
 
A minimum clearance of approximately 5 feet is provided between the basin 
bottom elevation and the estimated groundwater depth: 13.1 feet (refer to 
Boring Log B‐2 in Appendix G). Side slopes are 4:1 with a 16’ maintenance 
access road. 
 
Once completed, the stormwater drainage system will direct the floodwater into 
the drainage system and away from any structures, property, and streets.  
Stormwater flood mitigation would have a definite benefit to health and safety 
(preventing flooding of structures, mold, and dangerous flash flooding of streets 
& alleys).  The goal of this mitigation project is to prevent loss of property and 
loss of life, while enhancing the quality of life within this historically 
disadvantaged community.  It will also improve road safety along the impacted 
primary transportation corridors.

Scope of work 
 
 
Who will 
manage and 
complete the 
mitigation 
activity? 
The City of Buckeye project management staff will coordinate with the Flood 
Control District of Maricopa County, as well as the contractors who will be 
performing construction activities. 
 
Will the project 
address the 
hazards 
identified and 
what risks will 
remain from all 
hazards after 
project 
implementation 
(residual risk)? 
Based upon the professionally prepared designs and studies, the project will 
address the issue of flooding for the 10-year, 2-hour storm for Downtown 
Buckeye. Additionally, the project will construct a basin to contain the 100-year 
stormwater runoff with a 10-year collection system. It is not expected that the 
risk of flooding in this area will further exist. 
 
 
When will the 
mitigation 
activity take 
place? 
Upon award and final execution of a grant agreement, the City of Buckeye will 
commence the procurement process to engage contractors for construction 
activities. Once the contractors have been procured, the construction activities 
will commence. The overall period of performance, including procurement and 
construction, will occur over a 36-month period.

Explain why this 
project is the 
best 
alternative. 
What 
alternatives 
were 
considered to 
address the 
risk and why 
was the 
proposed 
activity 
considered the 
best 
alternative? 
Discussions were conducted in regular meetings with the FCDMC, the City 
of Buckeye, and Dibble Engineering to identify potential flood control 
alternatives to supplement or replace the concepts developed in the Final 
Pre-Design Assessment Report by PEC. Through this process, several 
alternatives were identified, including a “do-nothing” alternative. 
Alternative 1- capture the 10-year storm event generated north of Monroe 
Avenue through a storm drain system in Monroe Avenue between 4th Street 
and 9th Street, basin outfall, and irrigation canal delivery to the Gila River. 
Advantages 
• 
Basin site contributes to a higher density of open space 
• 
Peak flows to the BWCDD are reduced from existing conditions 
• 
No need for new infrastructure for downstream conveyance 
• 
The majority of DDS flows are retained for the 10-year storm event 
• 
Significant cost reduction solution

Alternative 3- Do nothing 
This does not fix the problem. Buckeye would continue to have annually 
recurring flooding and damage. 
Please identify 
the entity that 
will perform any 
long-term 
maintenance 
and provide a 
maintenance 
schedule and 
cost 
information. 
The 
subapplicant or 
owner of the 
area to be 
mitigated is 
responsible for 
maintenance 
(including costs 
of long-term 
care) after the 
project is 
completed? 
The City of Buckeye, Public Works Department (BPW), will provide 
annual routine maintenance and long-term care for the proposed project after 
its completion. 
Annual cost is estimated to be between $10,000 and $15,000. This cost 
generally includes personnel, labor, equipment, recordkeeping, reporting, 
training, and contracted services. 
BPW currently maintains an experienced staff to handle these routine functions, 
providing similar maintenance to all of Buckeye’s 640 square miles of city 
infrastructure. The new stormwater infrastructure will be folded into the citywide 
regular maintenance schedule.

In June 2004, Project Engineering Consultants, 
Ltd. (PEC) met with Buckeye City staff, made 
several site visits, and reviewed the provided 
utility documentation during the course of the 
study. PEC Engineers also met with the 
management of the Buckeye Irrigation District 
and the Arlington Canal Company to determine 
the feasibility of using their facilities as a 
discharge location. Buckeye staff and PEC also 
attended a public meeting held in the Buckeye 
Community Center with the Flood Control 
District of Maricopa County (FCDMC). PEC 
surveyed a portion of the area to obtain 
additional data. PEC concluded that it is 
reasonable to construct a basin to contain the 
100-year stormwater runoff with a 10-year 
collection system. PEC recommended the 
development of a major storm drain system 
along Monroe Avenue, a multi-use detention 
basin, and an outfall corridor to discharge the 
storm water into existing irrigation district 
facilities leading to the Gila River. As the City 
continues to grow and develop, this proposed 
drainage system in the downtown area will 
become increasingly important in minimizing 
the impact of future storm events in the City of 
Buckeye.  The most recent major flooding event 
occurred on 10-16-22.

Describe involvement of partners to enhance 
the mitigation activity outcome. 
The elected and appointed officials of Maricopa 
County and the 27 other participating 
jurisdictions demonstrated their commitment to 
hazard mitigation in 2014-2015 by preparing 
the second update of the Maricopa County 
Multi-Jurisdictional Hazard Mitigation Plan 
(2015 Plan).  
 
The City of Buckeye has an Intergovernmental 
Agreement with the Flood Control District of 
Maricopa County, wherein Buckeye hopes that 
the Flood Control District will contribute to the 
project cost. This partnership ensures the 
project meets community needs, ensuring the 
project meets overburdened and underserved 
population needs, making a financial 
contribution, providing educational resources, 
and coordinating multi-jurisdictional projects to 
include this proposal. 
Discuss how anticipated future conditions are 
addressed by this project. 
The completion of the Downtown Buckeye Flood 
Mitigation project will prevent flood damage to 
residential and commercial properties and any 
subsequent related negative impacts on the 
population in the affected area.

Location 
Project Location 
 
Provide a detailed description of the proposed 
project's location. 
The Downtown Buckeye Flood Mitigation project 
includes the installation of a storm drainpipe 
and catch basins along E. Monroe Ave. from 
Miller Rd. to 9th St. This system will relieve the 
issue of flooding for the 10-year, 2-hour storm 
for Downtown Buckeye. The waters would be 
conveyed in a storm drainpipe system under S. 
6th St. to South St. At South St., the pipe system 
would travel east to 7th St. and outfall into a 
retention basin constructed by this project.

Project Benefiting Area 
 
Provide a detailed description of the proposed 
project's benefiting area 
The project is located in the City of Buckeye, 
located in Maricopa County, Arizona. Buckeye is 
a rural area with population clusters spread 
over 640 sq. miles, covered by greater than 
90% agricultural/open space, 2% 
industrial/commercial use, and 4% residential. 
Buckeye is located 40 miles west of Phoenix 
and consists of 640 square miles. Buckeye is 
home to approximately 114,000 people. 100% 
of the downtown population of about 31,000 
resides in the proposed project’s benefiting 
area. Median household income is estimated at 
$57,000. There are about 30 businesses in the 
impacted/benefitted area. Buckeye’s 2024 
main ethnic breakdown is 35% Latino, 48% 
White, 8% Black, and 9% other. The World 
Population Review estimates the median 
household income for 2024 is $94,188, the 
median age is 35 years, and 8% of households 
are below the poverty level. Portions of 
Buckeye, including the benefitted area, have 
been federally identified as historically 
disadvantaged as to transportation, health, 
equity, environmental indicators, Risk 
Management Plan (RMP) facility proximity, 
wastewater discharge, flood risk, education, 
income, socioeconomic indicators, 
unemployment, and a high level of vulnerability 
to negative effects caused by external stresses 
on human health. This includes the affected 
area of this project. 
The total population affected is 27% (31,000 / 
114,000 = 0.2719 (27.19%)).
