Updated Stormwater Management Design Manual
The updated Stormwater Design Manual will be effective starting June 3, 2013. The revisions include the requirements to meet the needs for Bridge Street Corridor development, additional clarification for stormwater control measure design, updated references for rainfall amounts and location of specific control requirements.
The 2013 Stormwater Design Manual includes several chapters that outline the requirements for designing a stormwater conveyance system in the City of Dublin:
Chapter 2 – Hydologic & Hydraulic Design Criteria
Addresses the specific design criteria required to design stormwater control measures in terms of the rate, volume and water quality. Climatological information is provided on the rainfall patterns and distribution to be used in preparing an application. The manual has been updated with different criteria depending on the location of the project. Additional guidance has been included for projects that are considered redevelopment projects.
Chapter 3 – Special Conditions and Constraints
Highlights site conditions that require supplemental protection or that potentially represent a hazard to the public health, safety or welfare are identified and protective measures are incorporated into the design of site improvements and storm water management measures. This section also establishes standards and demonstrations for approval that are consistent with other regulatory requirements and procedures applicable to development within the City of Dublin.
Chapter 4 – Flow Conveyance
Provides standards and criteria to ensure the safe and effective flow of storm water through flow paths, treatment facilities and the physical storm drainage system in a manner consistent with protection of the public health, safety and welfare; the safety and function of properties, roads and improvements; and maintaining and improving water and environmental quality in the City of Dublin and its surface waters.
Chapter 5 – Stormwater Control Measures
Defines the approved stormwater treatment and control measures and practices for use in the City of Dublin. Design guidance and requirements for each type of control measure are presented in a table with accompanying figures.
Chapter 6 – Bridge Street District Integration with Stormwater Management
Defines and describes the manner in which recommended stormwater treatment and control measures (as defined in Chapter 5) may be used in specific areas of the Bridge Street District. This Chapter is intended to support the general purpose, scope and intent of the Bridge Street District by promoting and facilitating the use of recommended stormwater control measures that are consistent with and suitable for particular street families, right-of-way elements, building types, building sites, and open space types, and which contribute to sound stormwater management in a walkable mixed-use development setting.
Chapter 7 – Stormwater Management Plan
Provides guidelines, standards and requirements for the orderly development, approval, and implementation of Stormwater Management Plans, including provisions for shared systems and ongoing maintenance. This Chapter sets forth the requirements for preparation and submittal of Stormwater Management Plans, and provides a framework by which property owners and public agencies may propose collectively an overall plan for managing stormwater from multiple properties, where such a management plan will enable greater consistency with the City’s adopted plans and policies. It is a further purpose of this Chapter to provide sufficient standards and safeguards for associated plans, approvals and agreements to protect the public interest by ensuring long-term management and maintenance of stormwater management facilities.
Chapter 8 – Erosion and Sediment Control
Provides standards and guidelines for the preparation of erosion and sediment control plans that protect public health, safety and welfare, and the quality of Dublin’s waters from excessive erosion and sedimentation resulting from the construction and operation of development.
