Stormwater Ponds in Coastal South Carolina Appendix A6-1 – Economic Survey Methods
Methods
In order to better understand the accrued costs of stormwater pond management and maintenance, we implemented an anonymous online survey and conducted directed interviews for pond owners, managers, HOAs, real estate professionals, and other stakeholders. The objective of the survey was to engage members of the pond management community to acquire information and data on the lifecycle costs faced by the various stakeholders.
The survey and directed interviews asked the stakeholders about direct and indirect costs of stormwater pond construction, permitting, maintenance, and other environmental costs. The responding managers and maintenance personnel reported the direct or economic costs of construction, permitting, and maintenance. The responding members of HOAs, for example, reported environmental costs and costs associated with ongoing maintenance.
The survey contact list was based on two different sources: the South Carolina Association of Stormwater Managers (SCASM) listserv and the South Carolina Department of Health and Environmental Control (DHEC). DHEC is responsible for the management of stormwater control throughout the state of South Carolina, including its eight coast counties (Drescher, 2007). The research team was granted permission to distribute the survey invitation via SCASM’s listserv. Thus, the survey was mostly distributed to stormwater practitioners and developers in the state of South Carolina.
The survey was ultimately distributed to approximately 500 individuals between the two databases of contacts. An initial invitation to participate with the survey was distributed on May 15, 2015, and two reminders were distributed to the contact list in two-week intervals following the initial announcement. Of these 500 invitees, approximately 68 individuals responded to the survey, which represents a response rate of 13.6 percent. Unfortunately, some of the respondents did not complete the survey, so we ended up with 58 fully completed responses.

Summary
As demonstrated below, approximately 68 percent of the respondents worked for the public sector and 18 percent worked for the private sector. The reader should bear in mind that unlike the literature review on stormwater maintenance costs, in which the researchers ascertained very specific information regarding costs, the purpose of the survey here was to gather initial information about maintenance activities and costs in state of South Carolina. (To the authors’ knowledge, this was the first survey of its kind in the state). In other words, the researchers’ objectives, within this study, were to gather information from the “30,000-foot” view of maintenance activities and costs in the state. (In the near future, the researchers plan to conduct a follow-up study and ask specific questions about maintenance and management costs regarding stormwater control). There is a large amount of data provided by the survey results, so for the sake of brevity we highlight some of the important findings here:
- Annual inspection budgets yielded bi-modal distribution of responses.
- The largest number of respondents had budgets that exceeded $50,000 per year, and the next largest number had budgets lesser than or equal to $10,000 per year.[1]
- About one-in-four inspections are for private (or residential) ponds and about three-in-four inspections are for commercial (non-residential) ponds.
- The largest number of respondents indicated that only one-in-four or less of their organization’s inspections include private stormwater ponds; however, most respondents indicated that three-in-four or more of their organization’s inspections were for commercial ponds.
- A relatively small portion of annual budgets is dedicated toward maintenance.
- The largest number of respondents indicated that less than $10,000 per year, of their organization’s annual budget, is dedicated toward stormwater maintenance and infrastructure development.[2]
- The total number of ponds managed by respondents varied greatly
- Six respondents identified fewer than 10 ponds and three respondents indicated greater than 70 ponds.
- A relatively small portion of pond construction is dedicated to retrofits.[3]
- The largest number of respondents indicated that only one-in-four or less of stormwater pond construction is dedicated to retrofits.
- New stormwater pond construction costs vary greatly.
- The largest number of respondents indicated that construction costs (excluding land costs) are less than $10,000 per acre.
- The volumes of new constructed ponds vary greatly.
- The largest number of respondents indicated greater than 60,000 cubic feet; however, the other respondents indicated all sorts of different volumes ranging from 10,000 to 60,000 cubic feet.
- Percentage of newly constructed ponds is relatively small each year.
- The largest number of respondents indicated that only about one-in-four ponds each year are dedicated to new construction; that is, of maintenance and construction activities, only 25 percent are dedicated toward new construction.
- Average land area for new pond construction is relatively small.
- A majority of respondents indicated that newly constructed ponds only require one to five acres of land.
- The costs of construction for Best Management Practice ponds vary.[4]
- A majority of respondents indicated that newly constructed BMP ponds cost up to $20,000 per acre.
- A majority of management companies have large maintenance costs occurring at least once per year.
[1] A large percentage of persons who responded to this particular question indicated that they did conduct maintenance inspections.
[2] Given the anonymity of the respondents to the survey, the researchers do not know if elected HOA boards (managed by residents) or representatives from contracted management companies were the largest population to respond to this particular question.
[3] The researchers did not explicitly ask whether retrofits included “maintenance activities” as well. The specific definition of retrofits was not offered to the respondents, but the intent of retrofit was for major pond maintenance activities including dredging. Further, it is possible that retrofits can extend the initial lifecycle of the pond.
[4] A Best Management Pond is simply defined as the type of pond given the environmental needs of a particular project or area. For example, for residential neighborhoods with a large amount of impervious surface and little additional land for development, a stormwater pond (wet pond) is generally the best solution – hence, it is referred to as a Best Management Pond.
