Ordinance No. 1275, Page 1 of 14 • • The City has adopted this stormwater management ordinance to help protect its resources from adverse effects of unmanaged stormwater runoff. Stormwater from a rain event, where runoff is the portion of stormwater that does not infiltrate into the ground or evaporate and is not intercepted before reaching a Stormwater Management System. Stormwater runoff from undeveloped lands usually does not require management since it does not have an opportunity to accumulate manmade pollutants or be in conflict with manmade improvements such as roads, buildings, etc. When land is converted to higher intensity land use, stormwater can become a problem if it is not properly managed. When areas are paved, and impervious surfaces are created it reduces infiltration rates and increases the direct runoff to municipal stormwater conveyance systems (storm sewers, swales, canals, etc.). In certain conditions, these increases in stormwater runoff can exceed the capacity of the conveyances which leads to localized flooding. Increases in pollutant loading to stormwater associated with development must also be managed. To address these concerns, stormwater management practices are implemented with development to mitigate increases in flood risk (water_ quantity) and increases in pollutant loading (water quality). Stormwater runoff contributes to pollutant loading to receiving waters. With the exception of man-made compounds, pollutant loading is found in all stormwater runoff in concentrations that are attributed to the land use. This includes undeveloped lands where nitrogen and phosphorous are present from decaying vegetative materials, fecal coliforms from birds and other animals, and even things like arsenic are naturally occurring. At their native concentrations, these pollutants are a necessary component of the environment and contribute to normal ecosystem function. Pollutant loading can become impactful to the environment when loading levels are unmanaged and elevated above natural concentrations over a prolonged period of time. Some specific sources where pollutant loading of: stormwater can become a problem originate from unmanaged municipal or vegetative waste, use of petroleum products (commonly from automobiles) unmaintained wastewater treatment systems such as septic tanks, over application of nutrient fertilizers and herbicides applied to lawns, and atmospheric deposition among others. Excess nitrogen (N) and phosphorus (P) nutrient loads are commonly attributed to residential and industrial land uses, commercial, mixed urban, and roadways can generate higher concentrations of metal contamination. Heavy metals are of particular concern because several are known to be toxic to native aquatic plant and animal species. Motor vehicles and road surfaces are the common sources of heavy metals in stormwater runoff. Nutrients and pesticides applied for lawn maintenance and atmospheric deposition can cause algal blooms and similar environmentally harmful occurrences if untreated runoff is allowed to enter surface waters. During a rainfall event, stormwater runoff mixes with pollutants either physically or chemically if they are water soluble and can carry them to surface waters. This is where unmanaged stormwater not only causes adverse environmental impacts but also economic impacts. An increase in the number of impervious surfaces raises the potential for flooding and property damage. Polluted stormwater can also lead to reduced fisheries production because of the degradation of water quality. For these reasons, stormwater management practices have been implemented throughout Florida and the United States. This Section is designed as a guide to best management practices (BMPs) for stormwater management in the City_ A stormwater management practice shapes and improves the quality and quantity of stormwater runoff being discharged to receiving waters. BMPs for stormwater are those that meet discharge quantity and quality criteria at a minimal cost. This article will be used to review and approve Stormwater Management Systems permitted by the City and will be modified as appropriate technology and regional stormwater rules dictate.

If applicable, language to be added is underlined. If applicable, language to be deleted is struck thfough. Ordinance No. 1275, Page 7 of 14 Lc. Water Quality Design Criteria. Stormwater designs must demonstrate a net improvement in nutrient loads or a 95 percent reduction in pollutant loads for the design level of service storm event adopted in the Code. This can be demonstrated through methods that are accepted by the SFWMD. Methods of Stormwater Treatment. Stormwater treatment facilities shall be designed to treat stormwater runoff to a level that meets the design criteria defined herein. The volume to be treated depends on the type of stormwater management facility(ies) used and the land use of the property. A detention facility collects and temporarily stores a treatment volume to provide for treatment through physical, chemical. or biological processes with subsequent gradual release of the stormwater to a surface water system. A retention facility is designed to prevent the discharge of a given volume; however, it is slowly released from the facility through infiltration and evapotranspiration. A retention or detention facility built at least 12 -inches above the groundwater table is "dry.' A facility with the bottom below the control elevation is "wet." The wet season water table plays an important part in the functioning of retention systems. To ensure that stormwater facilities continue to function in the future, a stormwater design will need to include a determination of the wet season water table. (i) Wet Detention. u Wet detention is the collection and temporary storage of stormwater runoff, before controlled discharge into receiving waters, in a permanently wet impoundment to provide treatment through physical, chemical, and biological processes with subsequent gradual controlled release of the stormwater. A wet detention facility is a basin or pond with a bottom elevation below the wet season water table or control elevation. Lel Method of Achievement. Constructed ponds on the site are . generally used for wet detention. These ponds must meet the following design criteria: A wet detention facility is usually wet and allows for 1/2 -inch of the required detained volume (1 -inch over the total basin area, or the total of 2.5 -inches times the percent of impervious area less roof and wet pond areas, whichever is greater) to be discharged through a control structure in no less than 24 -hours. Catch basins, pipes, swales, or channels are used in areas with large amounts of impervious surface to collect runoff and convey it to the detention facility. The required design criteria of a wet detention facility are detailed below: a. The pond must be at least 0.5 acre and at least 100 -feet wide for lakes exceeding 200 -feet in length. b. Irregularly shaped lakes may be narrower than 100 -feet in some portions but should average 100 -feet in width. c. Projects with single -owner entities or entities with a full-time maintenance staff with obvious interests in maintaining the areas for water quality purposes may have the area and width criteria waived. d. The lake slopes should be at least 4:1 (horizontal to vertical) to a depth of 2 -feet for safetv reasons and to allow a littoral habitat to form. e. The control structure is at one point in the detention facility. Trash collection screens are required on structures discharging to surface waters. f. The control structure must be opposite from the runoff entry into the facility to prevent hvdraulic short-circuitina and to ensure full treatment. For non-residential projects, wet detention cannot be used as the sole form of stormwater treatment. If wet detention is used, at least 2.5 -inches of dry retention pre-treatment must be provided for the whole project area. Guidance on sizing, designing, and permitting wet detention facilities or exfiltration trenches can be found in the SFWMD Environmental Resource Permit Applicant's Handbook. If applicable, language to be added is underlined. If applicable, language to be deleted is skask tkeugh. Ordinance No. 1275, Page 8 of 14 • Dry Retention. M Dry retention is a stormwater system designed to prevent the discharge of a given volume of stormwater runoff into surface waters by complete onsite storage of that volume. A dry retention facility has a bottom elevation at least 1 -foot above the future wet season water table and is usually dry. Stormwater is released only during times of heavy rainfall or flooding. u Method of Achievement. Examples of dry retention facilities include infiltration systems (e.g., vegetated swales and bioretention systems) and seepage systems (e.g., exfiltration trenches, pervious pavement, and exfiltration vaults). Of these two, infiltration systems provide better pollution attenuation. The vegetation takes up a percentage of the nutrients commonly found in stormwater runoff. Most heavy metals bind with the soils above the water table and the potential for them entering the groundwater is reduced. Seepage systems consist of an underground facility that relies on a mostly outward dispersion of stormwater from the facility to the groundwater. These structures are constructed a minimum of 1 -foot above the future wet season water table. These systems are most suitable for areas where the soil has high transmissivity. However, they do not provide the nutrient uptake that is offered with vegetated infiltration s sy tems. Infiltration systems and seepage systems need a highly permeable substratum to allow the stormwater runoff to percolate into the ground. Seepage systems do not require as much land area as infiltration systems since they can be installed underground. However, the future wet season water table at the project site must be at least 1 -foot below the seepage structure. (k) Dry Detention. Dry detention systems are designed to store a defined quantity of runoff from a completed development and slowly release the collected runoff through an outlet structure to adjacent surface waters at downstream, pre -development flow rates. Method of Achievement. Examples of dry detention facilities include impoundments and excavated basins. Treatment volume shall consist of on-line or off-line detention of the first 0.75 -inches of runoff or 1.88 -inches times the percentage of imperviousness; whichever is greater. Systems shall recover 50 percent of treatment volume in 24 -hours. Dry detention systems are limited to project areas less than 5 acres in size, and which serve a drainage area less than 5 acres in size. Control Structures. u Definition. A control structure is a device through and/or over which water is discharged from a Stormwater Management System. Direct discharge occurs when stormwater is released through a control structure to the receiving waterbody• If the discharge from the Stormwater Management System is by a means other than a control structure (e.g., sheet flow or spreader swale), it is considered indirect discharge. Purpose. The primary purpose of a control structure in a detention facility is to release the calculated runoff volume slowly over a specified period. In a retention facility, the control structure allows for volumes exceeding the calculated retention volume to leave the system in a manner that orovides adeauate downstream flood protection, (3) Types of Control Structures. Direct discharge from a water management facility to the receiving body is usually achieved through control structures such as weirs and orifices. The following criteria must be met for all methods of direct discharge: a. Trash collecting gratings and oil skimmers must be installed on the intake of all structures that discharge to surface waters. If applicable, language to be added is underlined. If applicable, language to be deleted is stFuGk through. Ordinance No. 1275, Page 9 of 14 • b. Detention facilities discharge must be above the permanent pool. c. If a non -single-family residential property is greater than 50 percent impervious or contains a system with inlets in paved areas, discharge structures must include a baffle, skimmer, or other suitable mechanism for preventing oil and grease from being discharged. d. Direct discharge will only be allowed to those areas that due to their large capacity or configuration are able to absorb concentrated discharges without erosion. When using indirect discharge to release stormwater, a spreader swale is commonly used. The swale is positioned parallel to the receiving body, and the side ad'lacent to the receiving body is lower than the side opposite the receiving body. The swale allows the water to flow into the receiving body but not flood the adjoining property. This method works well when trying to maintain a proper water level in wetlands that are used for stormwater management. The spreader swale is also a treatment facility for stormwater runoff. Runoff exceeding the first flush is allowed to enter the wetland system via sheet flow. Lml Criteria for Single-Family/Duplex Lots. Lots Within Subdivisions With Approved Stormwater Management Plans. In all subdivisions that have an approved Stormwater Management Plan, all new development must comply with the approved Plan. A lot Grading Plan, complete with topographic information that complies with this Section, must be submitted for review before the issuance of the buildinc, permit. If the approved Stormwater Management Plan does not contain sufficient lot grading information to verify that the lot being permitted will drain in accordance with the Plan, the requirements of Section 2 herein shall apply. Lots Within Subdivisions Without Approved Stormwater Management Plans. Single- family and duplex homes that are not part A a stormwater drainage system shall provide a Stormwater Management Plan following the guidelines established herein. The design criteria generally use vegetated swales. However, other retention practices may be used. The retention volume specified in these design criteria will provide adequate stormwater treatment on a single-family/duplex lot to meet the City stormwater treatment requirements. However, calculations demonstrating a net improvement in nutrient loads may be submitted as an alternative to using the retention volume specified in these design criteria. The stormwater calculations must be completed by a Florida registered and licensed professional engineer. The retention volume depends on the lot size and the Stormwater Management System used. Stormwater treatment can also be provided using other retention systems such as pervious pavement, exfiltration trenches, or shallow stormwater vault systems. If swale(s) are used, they must meet the following criteria: a. Runoff from the site must be drained to the swale. b. The swale length must be greater than its width. c. The swale side slope must be 4:1 (horizontal to vertical) or shallower. d. The swale must be placed so that any atural areas to be preserved are not disturbed. e. The swale must be at least 6 -inches f. Swales should be vegetated. If a swale is not vegetated, a 6 -inch layer of soil amendment formulated to reduce nutrient loading must be installed directly below the swale. Specifications and published nutrient reduction test results for the soil amendment media must be provided at the time of testing. If applicable, language to be added is underlined. If applicable, language to be deleted is struck through. Ordinance No. 1275, Page 10 of 14 For retention systems, a control structure will allow runoff exceeding the volume of the swale to be discharged to the receiving body. More than one retention system may be on the property provided that each meets these criteria, and the total volume of the retention is at least the calculated volume. Vegetated swales may be incorporated into the set -back area of land required by the City. Section 78-107. Dedication or Maintenance of Stormwater Management Systems. (a) Dedication. If a Stormwater Management System approved under this Code will function as an integral part of the City maintained regional system, as determined by the City, the City shall have the option of requiring that the facilities be dedicated to the City.
