Stormwater runoff is generated when rain or melted snow flows over land or impervious surfaces, such as paved streets, parking lots and building rooftops, and does not soak into the ground. As the runoff flows over the surfaces, it accumulates debris, chemicals, sediment or other pollutants that could adversely affect water quality if the runoff is untreated.
In natural areas, stormwater runoff is absorbed by the ground. It is filtered and ultimately replenishes underground water deposits or flows into waterways. In developed areas, impervious surfaces prevent stormwater runoff from naturally soaking into the ground. Instead, the stormwater runoff rapidly enters storm drains, sewer systems and drainage ditches. This can cause:
The City owns and maintains a system of inlets, ditches, pipes and ponds that are designed to carry stormwater runoff away from streets and buildings to the waterways. Unlike sanitary sewer systems, the storm sewer system does not lead to a treatment plant. It carries stormwater runoff directly to local waterways.
Dublin is well known for its parks and open spaces, which also include our many waterways. The City’s Community Plan calls for providing for safe and efficient collection of stormwater and continuing to maintain and improve the water quality of the Scioto River and its tributaries.
Dublin is also required by the United States Environmental Protection Agency to comply with its National Pollutant Discharge Elimination System Phase II municipal separate storm sewer system program. This program requires local governments with fewer than 100,000 people to develop a plan to reduce stormwater pollution in order to protect and improve waterways. The Ohio EPA manages the compliance of the local jurisdictions with their NPDES Phase II MS4 permits.
The program is comprised of six control measures that when implemented should result in a significant reduction of pollutants discharged into receiving waters. The control measures are:
The City has developed an updated Stormwater Management Program Plan that outlines how the City will meet the minimum control measures during the current permit term.
The City is required to submit an annual report that demonstrates how the City addressed each of these minimum control measures. Click here to review Dublin’s 2016 NPDES report.

Commercial properties and managers can learn more about:
The City has developed both the current stormwater code and the Stormwater Management Design Manual. The purpose of these is to set the City’s standards for stormwater management and to maintain uniformity in the design standards used for stormwater management. The Manual enables the City to provide effective and efficient review of design data and to provide designers with clear guidance in preparing stormwater management plans. These plans and designs are routinely reviewed for each development project and are contained in the applications that are reviewed by the Planning and Zoning Commission.
Through the standards and practices incorporated in the Manual, the City encourages the use of stormwater treatment and engineering methods that allow for groundwater recharge and that manage stormwater as close to its source as possible. Specifications for stormwater control measures that use vegetation and soil media to filter, treat or infiltrate stormwater, often referred to as “Low Impact Development” or “LID BMPs,” have been incorporated into this Manual. These practices are encouraged to be used in Dublin where suited to the site and development conditions.
This interim update has modified the water quality calculations (WQv), rainfall depth (for WQv calculations), and references for the current Ohio EPA Construction General Permit (OHC000005) to comply with the current Ohio EPA Construction General Permit.
Dublin has participated in the National Flood Insurance Program (NFIP) since 1980 by Ordinance 27-80. The NFIP makes flood insurance available to property owners in communities that agree to adopt an ordinance regulating development in flood prone areas. The floodplain regulations required by NFIP are designed to accomplish three basic objectives related to flood damage protection:
Dublin’s code exceeds these minimum requirements. Chapter 151 – Flood Controlrequires the necessary controls and provisions, but also includes a 20 foot buffer zone to floodways. No fill shall be placed between the floodway and the base flood elevation (flood fringe) or between the floodway and 20 feet from the floodway, whichever is less. See the graphic below for additional clarification.
Under NFIP, the Special Flood Hazard Area (SFHA), otherwise known as the Floodplain or 1 percent chance of a flood, is the area of land that would be inundated by the base flood (see the above graphic.) This floodplain is the area regulated by Dublin for compliance with the NFIP and where the mandatory flood insurance purchase requirement applies. The floodplain is shown on the Flood Insurance Rate Maps (FIRM) provided by the Federal Emergency Management Agency (FEMA). These are the maps that lending institutions use to determine if floodplain insurance is required for a property.
If you are doing work in the SFHA, you will be required, as part of the building permit, to also submit a Special Flood Hazard Area Development Permit Application (SFHADPA) along with the required fee. Engineering will review the application for compliance with Chapter 151 – Flood Control Requirements. To assist applicants with obtaining SFHA Development Permits, the City has developed an Administrative Policy – Special Flood Hazard Area Permitting. Click here for a link to the Policy. Follow this link to the application forms Click here for form.
Over the years FEMA has updated the maps with current information obtained from studies and applications to change the maps. In 2005, FEMA initiated a Multi-Hazard Flood Map Modernization effort, which will result in the improved accuracy and expanded utility of the of the nation’s current flood map resources. Click here for a more detailed explanation of the changes to the maps. These maps are effective June 17, 2008.
Number of Parcels Affected | Cause of Change
59 | New to the Flood Fringe
32 | New to the Floodway
55 | Removed from Flood Fringe still in Floodway
81 | Removed Flood Fringe and Floodway
16 | Removed from Floodway still in Flood Fringe

In order to support faster response and better tracking of requests, the City of Dublin uses JustFOIA to collect, respond to and manage public information requests.
JustFOIA is a Freedom of Information Act (FOIA) online application that helps streamline the open records request process for the community and improve efficiencies in getting requested information quickly and accurately.
The application lets community members submit requests for all city records, including police reports. Commonly requested information includes accident reports, copies of resolutions and body-camera video.

This Revised Charter, as adopted on March 19, 1996, became effective on July 4, 1996.
The Zoning Code for Dublin is Chapter 153 of the Dublin Code of Ordinances. The Zoning Code sets land development requirements and establishes different uses within individual districts. Zoning regulations address the physical development of a site, such as building height, lot requirements, setbacks from lot lines, minimum numbers of parking spaces, sign types and sizes, and other related regulations.
