Water Management Cluster

An industry “cluster” is a regional concentration of related economic activities. The Coastal Index defines the water management cluster as the set of activities related to coastal restoration and protection, urban water management, and subsidence management. To quantify this cluster in a manner that is consistent with available industry-level employment data, The Coastal Index combines two clusters from Harvard’s U.S. Cluster Mapping Project, which classifies standard industry definitions (NAICS) into mutually exclusive clusters based on inter-industry trade patterns and geographic concentration. As classified by that research, the “construction products & services” and “business services” clusters encompass many of the activities most closely associated with the design and protection of coastal protection and water management infrastructures. The construction products & services cluster includes advanced construction industries imperative for moving earth and water, and the business services cluster includes important high-skill industries necessary for the design, engineering, and system integration of coastal and inland water management projects.

The U.S. Cluster Mapping Project is a national study. Although a useful benchmark, like any method for categorizing economic activity, it has limitations. For example, emerging and uniquely localized industries and industry clusters, such as water management, are likely to be imperfectly classified because the data is based on previous years and the general industrial makeup of the nation. In addition, the U.S. Cluster Mapping Project treats every cluster as mutually exclusive and each industry as belonging to a single cluster. Thus, the definition of water management used here undoubtedly both undercounts and overcounts employment for different industries within the cluster. For more detail on these issues, see a recent The Coastal Index companion brief entitled, Changing coast, evolving coastal economy: The water management cluster in Southeast Louisiana in retrospect and prospect, which discusses conceptual and methodological limitations of industry cluster definitions, both in general and with specific references to water management. The report also conducts a more detailed industry-level analysis to refine the cluster definition and to identify large, growing industries within the cluster.

To give an example of the challenge with defining water management activities, because there is no dedicated industry category for the construction of levees and related coastal infrastructures, these activities are most likely to fall under “Other Heavy and Civil Engineering Construction” instead of a more specific heavy infrastructure category. Indeed, this industry is extremely concentrated in Southeast Louisiana, and its employment has doubled since before Hurricane Katrina. As a result, employment in this industry can be linked to coastal protection and water management with confidence. In contrast, Engineering Services, though large and clearly related to the design of water management infrastructures, cannot be as directly linked to water management activities. It bears emphasis that similar definitional issues are common to cluster studies.

Super Region

The Southeast Louisiana Super Region is composed of the three metropolitan statistical areas (MSAs) – New Orleans-Metairie, Baton Rouge, and Houma-Thibodaux – and two additional parishes – Tangipahoa and Washington. There are 21 parishes in the Super Region. Our previous research found that the parishes in the Super Region were highly synergistic and interconnected. Economic development leaders have formed the Southeast Super-Region Committee (or SoLA) to collaborate across this broader geography. The economic data in this report reflects all of these parishes as a single unit. The terms “Super Region” and “Southeast Louisiana” are used interchangeably.

Super Region Map

Comparison metros

For some indicators, the Southeast Louisiana Super Region is compared to a group of nine metros that have comparable regional specializations in water management: Denver, Tampa, Houston, St. Louis, Charlotte, Baltimore, Virginia Beach, Austin, Orlando

These metros were selected for their similarities to the Super Region across a number of different measures. The most important similarity among the chosen metros is an employment concentration in water management industries, for which we considered two criteria. Eight of the nine metros have either a water management location quotient greater than one or a water workforce (as defined according a 2018 report from Brookings that used a different definition than The Coastal Index) that makes up at least 1.2 percent of its employment, which puts them among the top 50 cities by share of water jobs. Four of the metros meet both of these criteria. Additional considerations are population size and Gross Domestic Product (GDP) per capita as approximations of the size and output of a regional economy (GDP per capita is commonly considered to be a proxy for standard of living). A final consideration is historical or cultural similarity to New Orleans. St. Louis, Tampa, and Houston have historical and geographical similarities with Southeast Louisiana. To smooth variation between these regions, they are represented as a composite “Comparison metro.”

Years of analysis

Most of the data included in this report covers 2010 to 2018, many of the indicators being annual averages over this time period. 2010 is a natural starting point for economic, social, and political indicators covered in this index as it was the first full year out of the Great Recession, as well as the year of the Deepwater Horizon oil spill.

Technical Notes

Demand Drivers

U.S. Army Corps of Engineers (Army Corps)

The source of all Army Corps contracts is USASpending.gov, a federal contracts database mandated by the Federal Funding Accountability and Transparency Act (FFATA) of 2006, managed by the Office of Management and Budget (OMB), and operated by the General Services Administration. The contracts data found in this database are from the Federal Procurement Data System-Next Generation. Army Corps contracts were all contracts that fell under “CORPS OF ENGINEERS - CIVIL WORKS (USACE)” for “funding_agency_name” in the USASpending.gov database (i.e., contracts that were funded by Army Corps of Engineers civil program financing).

Construction and Services Contracts

Contracts that fall under services are those for which the NAICS code description includes the word “services.” Those under construction are those for which the NAICS code description includes the word “construction.” Contracts with a NAICS code that did not include the words “services” or “construction” fell into the miscellaneous category. All data collected were on prime contractors only. All negative entries were excluded.

In order to collect data exclusively on contracts performed in Louisiana between 2010 and 2018, The Data Center restricted the data from USASpending.gov to only contracts where Louisiana was the principal place where work was performed between the years 2010 and 2018. Yearly contracts represent awards between 2010 and 2018, but not necessarily completed contracts.

USACE Location of Firms

When collecting data on Louisiana-based firms and outside firms, The Data Center used vendor locations specified in the USASpending.gov data. The location of performance state was defined as the state where the majority of the work was performed.

The Coastal Protection and Restoration Authority

Projected Expenditures

Data comes from CPRA projections of expenditures in six categories for fiscal years 2020, 2021 and 2022. FY 2018 begins halfway through 2019, and FY 2021 ends halfway through 2021.

CPRA Regular Services Contracts

Data reflects records gathered manually from paper IDIQ services contracts awarded since 2010 under the following RFP/RSIQ types: “Environmental Sciences Consulting, Engineering, Surveying, Geotechnical, and Professional Land.” Contract amounts come from LaTrac, a database maintained by the Louisiana Department of Administration that keeps record of all given contracts. These contracts are “Indefinite Delivery, Indefinite Quantity,” which means that final contract work may total to less than the full amount. Not included are one-off service contracts, often associated with a specific disaster or project, and support service contracts, usually administrative contracts. Three engineering contracts are not included in the data because contract amounts could not be confirmed. Services contracts data reflect only CPRA-led projects where indicated.

CPRA-Led Construction Contracts

Data reflects a combination of internal CPRA data on costs for projects completed between 2007 and 2016, cash transfer data gathered by GNO Inc. in collaboration with CPRA, and CPRA construction completion reports. Cash transfers reflect cash transfers between CPRA and vendors associated with specific projects completed between 2007 and 2014. Prime construction contract amounts are a combination of those taken from completion reports and additional construction contracts greater than $2,000,000 from cash transfer data. Other cash transfers reflect support services, one-off services, oversight, and regular services task orders along with administrative costs. Construction contracts data reflect only CPRA-led projects where indicated.

The full value of a construction contract is reported in the year the contract was awarded. However, there are uncompleted construction contracts awarded between 2007 and 2014 not included in this data. Likewise, there are construction contracts completed between 2007 and 2014 awarded before 2007 not included in this data.

Partner-Led Contracts

Federal, state, and local partners in CPRA partner-led projects give out their own construction and services contracts. In addition, CPRA may give out contracts associated with planning and designing partner-led projects. Partner-led project data reflects total project costs, encompassing all associated contracts (construction, services, miscellaneous, admin) and admin/other costs.

CPRA Location of Firm

For services and construction contracts, a Louisiana firm was defined as a firm headquartered in the state of Louisiana as specified by Manta, an online directory of businesses.

For regular services contracts, successful proposers also listed the number of employees domiciled in Louisiana as well as the number of employees working on the project outside the state. Thus, this additional data was gathered and used to calculate the contracts that had a majority of Louisiana employees working on the project, despite the firm headquarters being located outside.

CPRA regular Service Subcontractors

Data for subcontractors comes from data gathered from regular services IDIQ contracts. In successful proposals, subcontractors were listed by primes, along with extensive information on each subcontractor’s qualifications. For many environmental science consulting, professional land, and surveying prime contracts, the anticipated percentage of contract going to each subcontractor was listed. The CPRA has no accounting for whether these subs were actually used and for what percent of the contract they were actually used. Dollar amounts are in 2016 inflation-adjusted dollars using the CPI-U-RS.

Mitigation banks

Mitigation banks data comes from RIBITS, the Regulatory In-Lieu Fee and Bank Information Tracking System, which was developed by the Army Corps to provide information on mitigation and conservation banking in the United States. In it, individual corps districts record every action taken by a mitigation bank sponsor with regards to a mitigation property. When a property is approved, the details are recorded, when credits are released, the details are recorded, and when credits are withdrawn (i.e. purchased), they are also recorded. Acre estimates are included as well for each transaction. Credits are released once a portion of mitigation work has been completed, so when credits are purchased, much of the restoration work has already been done.

Market Cap

Wetland credits vary in price depending on wetland type, location, supply, and numerous other factors. The $25,000 estimated price per credit comes from a GNO Inc. report on the mitigation banking market that identified $20,000 as the average credit price in SE Louisiana in 2012. Prices have likely increased since 2010, hence the higher estimate. Coastal wetland credit prices can get as high as $100,000 while inland forested wetland prices can dip as low as $5,000.

This data does not include any in-lieu fee program mitigation or permittee-responsible mitigation, which is mitigation done in an ad-hoc manner when sufficient or appropriate bank credits are not available in a given watershed. These two not-included types of mitigation were calculated by an Army Corps report in 2014 to be 3 percent and 18 percent of total mitigation in the Mississippi Valley, collectively 21 percent. As a result, the market cap value of wetland mitigation bank credits included in this report may underestimate the full value of mitigation work in Louisiana.

Louisiana Contractors Performing Work Outside of Louisiana

Data reflects highest total obligated amount (in dollars) by the Army Corps to companies with headquarters within Louisiana for contracts performed outside Louisiana between 2010 and 2018. Totals may reflect multiple contracts across multiple states and multiple years. Company names reflect vendor names reported at the time and may include companies no longer headquartered in Louisiana, or vendors that have since been purchased by outside firms.

Competition Between States for Army Corps Contracts

In-state total reflects the total obligated amount (in dollars) by the Army Corps to companies with headquarters within that state for contracts performed within that state. In-state share is that total divided by the total obligated amount for contracts performed within that state. Out-of-state total reflects the total obligated amount to companies with headquarters within that state for contracts performed outside the state. Out-of-state share is that total divided by the total obligated amount for contracts performed outside of that state.

Industry & Workforce

Water management job growth and wages

The data used for the water management average annual wage, job growth, location quotient, and demographic indicators come from Economic Modeling Specialists Intl (EMSI). EMSI is a private data provider that compiles high-quality employment data by removing the suppressions that are characteristic of publicly available county-level datasets. In addition to relying on federal datasets, EMSI uses data from the Louisiana Workforce Commission to improve their measurement of local industries, occupations, wages, skills, education, and training. The 6-digit NAICS codes that comprise the Data Center economic definition of water management can be found in the downloadable data tables.

Social Context

Educated Workforce

Educational Attainment

Data reflect the U.S. Office of Management and Budget definitions of the comparison metros from September 2018 for 2000 and 2018 data and from December 2009 for 2010 data. For the Southeast Louisiana Super Region, the data reflects the current definition of the region, which includes the New Orleans, Baton Rouge, and Houma-Thibodaux Metropolitan Statistical Areas, in addition to Tangipahoa and Washington Parishes. For the 2010 data, Washington Parish is not included because the population of the parish was <65,000 at the time so educational attainment numbers could not be obtained due to American Community Survey population cutoffs. Populations with at least some college include those who have attained no degree, an Associate’s degree, a Bachelor’s degree, and/or a graduate or professional degree. Populations with a Bachelor’s degree or higher have either a Bachelor’s degree, and/or a graduate or professional degree.

Science, Engineering, and Technology Bachelor's

Data is from the National Science Foundation publication of Science and Engineering Indicators 2018. The SEI is prepared by the National Center for Science and Engineering Statistics (NCSES), a part of NSF. The SEI is a record of indicators that provide information on the science and engineering sector of the economy.

The Science and Engineering Bachelor’s per 1000 individuals, 18-24 years old data reflect NSF analysis of data from the Integrated Postsecondary Education Data System (IPEDS), as well as Census Bureau population data. Eighteen to 24 year olds were chosen to represent the age of the majority of people pursuing a Bachelor’s degree. Science, Engineering, and Technology was defined by NCSES as physical, life, earth, ocean, atmospheric, computer, and social science; mathematics; engineering; psychology; science technologies; and engineering technologies. The state rankings shown are out of all 50 states and the District of Columbia.

State Funding for Higher Education

Funding dollars are adjusted by the SHEEO Higher Education Cost Adjustment (HECA), which adjusts for inflation based on the typical spending of a public higher education institution, rather than the spending of a typical consumer. Educational appropriations are a measure of state and local support available for public higher education operation expenses, including ARRA funds, and exclude appropriations for independent institutions, financial aid for students attending independent institutions, research, hospitals, and medical education. Full-time equivalent enrollment (FTE) equates student credit hours to full-time, academic year students, but excludes medical students.

Philanthropic spending

The data used for the philanthropic support indicators comes from the Foundation Center. Foundation Center is the leading source of philanthropic information with the most comprehensive database on United States grantmakers and grants. The Foundation Center compiles their data from IRS information returns, grantmaker websites, annual reports, printed application guidelines, the philanthropic press, and more than 30 other sources. The Foundation Center only has data on foundation grants, not individual donations.

Total and environmental grant giving were calculated by summing the grants that were awarded by grantmakers located in the Super Region and used for projects within the Super Region.

Research & development

Data are from the National Science Foundation publication of Science and Engineering Indicators 2018 (SEI). The SEI is prepared by the National Center for Science and Engineering Statistics (NCSES), a part of NSF. The SEI is a record of indicators that provide information on the Science and Engineering sector of the economy.

Academic Science & Engineering

The academic Science & Engineering R&D per $1,000 GDP data reflects the ratio of Science and Engineering R&D expenditures at colleges and universities within a state to the size of the state’s economy. Data reflects the NSF definition of Science and Engineering as the fields of: physical, life, earth, ocean, atmospheric, computer, and social science; mathematics; engineering; and psychology. Academic research accounts for about 15 percent of the all research and development done in the United States and more than half of basic research. Academic R&D can serve as an important indicator for future knowledge and economic progress. R&D data after 2009 comes from the NCSES Higher Education Research and Development Survey, while data before 2009 comes from the NCSES Survey of Research and Development Expenditures at Universities and Colleges, where data on expenditures by field are collected. Academic R&D is only reported for institutions with more than $150,000 in R&D.

Business-Performed

The business-performed R&D per $100 private industry output data reflect the share of R&D in the business activity of a state. Private industry output is a BEA-designated subset of GDP that is the part of GDP that is added by businesses. For business-performed R&D data, the NSF used two surveys. The Survey of Industrial Research Development, an annual survey completed by companies to create industry performed R&D information, was used by the NSF until 2007. Subsequently, the Business R&D and Innovation Survey, led by the Census Bureau, was launched. The new survey is better designed to capture R&D as it is currently conducted. These two surveys have consistent findings.

Federal Obligations

The federal R&D obligations per employed worker data reflects geographical disbursement of federal R&D obligations relative to the size of the employed workforce in a state. The dollar amount is accredited to the state of residence of the recipients. The data on federal R&D obligations were collected from the NCSES which carries out an annual census of federal agencies. The data on state workforce were taken from the BLS.

State Agency

The state agency R&D per one million dollars GDP data reflect the ratio of R&D funded by state agencies to the size of the state’s economy. Data reflects the NSF definition of state R&D funding, excluding state-run universities and colleges or college-controlled laboratories. The data also excludes any appropriations to non-state agencies that come directly from the state legislature. The state R&D data was collected through NCSES’s Survey of State Research and Development, a biennial survey to determine expenditures by performer, source funding, and type of R&D. The BEA’s data for GDP was used for output.

Coastal Change

Projected Coastal Land Loss

The two maps represent the 2017 Coastal Master Plan’s predicted land change over the next 50 years under a medium environmental scenario. The map titled “Land Loss With Plan” shows predicted land change with implementation of the master plan, and “Land Loss Without Plan” shows predicted land change if no further action is taken to restore Louisiana’s coast.

Population Change

The U.S. Postal Service (USPS) defines a residential address as actively receiving mail if mail has been picked up within the previous 90 days. In rural areas, mail is frequently delivered to rural route boxes and P.O. boxes rather than street addresses, and thus may lead to an undercount compared to Census Bureau occupied housing units. The most common city or place is listed along with the ZIP code.
