Stormwater

The Adopt A Road Program allows residents to directly enhance pollution prevention to our surrounding surface waters. These valuable volunteers assist in the collection of right-of-way trash before it has a chance to enter our storm system and surface waters.

If you wish to Adopt A Road, please contact the City of Oviedo Stormwater Administrator.

• Participants must enter into a two-year agreement and sign a liability waiver. 
• Participants shall provide the name of the group or family to be displayed on signage that will be placed at the beginning and end of the adopted roadway segment.
• Participants will remove trash along the adopted roadway a minimum of six times per year.
• Participants will report to the Stormwater Administrator the date and amount of trash collected; trash is normally collected and estimated in fifty-gallon trash bags.  If more than three pick-ups are missed, that portion of the roadway will be placed for re-adoption, and the current signage removed.
• Collection bags should be left tied to the signage pole for pick-up by the Public Works Department.
• All adopting parties will be announced in the Oviedo in the News publication and on the City’s social media sites.

Adoptable Roadways

Community Rating System & Flood Warning System

Since 2008 The City of Oviedo has been an active participant of the Community Rating System (CRS) governed by FEMA. The City's rating in the program allows premiums on flood insurance policies through the NFIP to be reduced by up to 25% for homes within a Special Flood Hazard Area. Most homeowners insurance policies do not cover flooding. Check with your agent to ensure flood coverage through the National Flood Insurance Program. The City's assigned number is 120293. Your insurance agent may request this number when you apply for flood insurance coverage. For homes not in a SFHA the premiums for coverage is minimal compared to the cost of a loss. 

Building Maximum Coverage

Contents Maximum coverage 

Rating for the Oviedo Community 

Class 5

This outstanding rating for the Oviedo community allows residents within a Special Flood Hazard Area (SFHA) who hold an insurance policy through the NFIP up to 25% of their premium.

Flood Details

The City strongly recommends all residents regardless of flood zone location or lender requirements to protect their investment and hold flood insurance for their home. Having an elevation certificate for your property is a valuable tool and allows insurance companies and lenders to appropriately assess the premium. Remember, a flood insurance policy takes 30 days to procure before a claim can be made, and flood insurance cannot be purchased during the onset of a natural disaster. 

For homes built pre-FIRM (Flood Insurance Rating Map), the home is required to be floodproofed should the structure receive damages from flooding exceeding 50% of the fair market value within a 10 year period. Building permits cannot be issued for substantial improvement or substantial loss until the requirement has been met. 

The City encourages residents and business owners to inquire if you reside within a specified FEMA Flood Zone or a Flood Prone area. You can reach the City's Floodplain Manager at 407-971-5682 or akortus@cityofoviedo.net. Those properties that fall within a Special Flood Hazard Areas or Flood Prone areas are at greater risk of encountering flooding from rising water due to daily thunderstorms, tropical storms or any other sever weather event. The City also advises homeowners to be informed of historic flood risks and events. The City encourages all residents to consider holding flood insurance coverage.

You may also wish to visit the FEMA website and review the content related to flooding, and also review the FEMA Flood Insurance Rate Map. This information can be found by visiting floodsmart.gov.

Flood warning system notification

The City of Oviedo Emergency Management will also provide reverse 911 message alerts for potential disaster events focusing on those homes or businesses that are specified within a Special Flood Hazard Area. To register, the property owner must have a landline telephone with a published phone number. Non registered or private numbers are not included in the alert method. 

Other Alerting Methods Suggested

We strongly recommend that all residents and business owners incorporate other alerting methods for potential Flood Watches or Warnings. These include a "weather alert radio", registering with a local news media website for "email or text message alerting" and monitoring local daily weather from both television and radio media outlets.

Wildlife Whereabouts

The City of Oviedo recognizes the importance of floodplain areas and the wildlife that live within them. The Floodplain Habitat & Species Plan is a way for residents of Oviedo to connect with their local wildlife and build awareness for the benefits the natural floodplains hold. Protecting these areas and preserving the wetlands can be achieved by reducing impacts from non-point source pollution, facilitating groundwater recharge and natural flood and erosion control. Additionally, preserving our natural floodplains and wetland areas reduces property damage for residents and business owners. Through this initiative, residents and visitors can submit photographs of their wildlife sightings by filling out the "Floodplain Species Sightings" form provided on this page or at signage in parks located around wetlands and floodplains in Oviedo. Once photograph submissions are approved and the species verified, they will be displayed on the interactive GIS map provided.

Property Preparation for Storm Season - floodsmart.gov

The City of Oviedo wants to inform residents about Flood Insurance and how to obtain information about their property and potential risks before a storm comes.

All properties, regardless of location, can flood. Where it rains, it can flood. Most basic homeowners insurance policies do not cover damages from flooding, even from roof damage. Check your policy to ensure you are covered, even if your lender does not require flood insurance coverage.

It is a good time now to be Flood Aware to ensure your home is covered from flood damages and your insurance policy is set as it needs to be in place 30 days before a major storm event for any flood related claims. Residents should know how they can prepare their property before summer storms and hurricane season is here. Listed below is some information the City can provide to help you navigate through the insurance process.  

• Staff can let you know if your property is shown on the most current Flood Insurance Rate Map (FIRM) and if there are any known unmapped flood risks or history of flooding. Flood risks can arise from wetlands, conservation areas, ponds, open space, rivers, streams, lakes, or any areas subject to localized flooding. Florida has a very flat topography with many rivers and lakes, and floods can occur even outside of the published SFHA's. 
• Additional flood data for a site, such as the base flood elevation or depth, can be provided by The City.
• The City maintains elevation certificates for new and substantially improved structures in the SFHA since January 1, 1987. The elevation certificates are stored at 1655 Evans Street, Oviedo FL. You can also get a copy by calling the Floodplain Administrator at 407-971-5682. 
• The City updates the Flood Insurance Rate Maps whenever revisions are made.
• The City also has information not shown on the FIRM, flood depth data, special flood-related hazards, historical flood information, and natural floodplain functions.
• One of the best protection measures for a building with a flood problem is a flood insurance policy under the National Flood Insurance Program, which can be purchased through any licensed property insurance agent. If the building is located in a floodplain, flood insurance will be required by most federally-backed mortgage lenders. Ask an insurance agent how much a flood insurance policy would cost.

If you would like to make an inquiry or need a copy of an elevation certificate or require a letter as verification, please tell us the street address and, if available, the subdivision, lot and block number. The City of Oviedo does not charge for this service. We are open from 7:00 a.m. to 4:00 p.m. Monday through Friday. Please contact the Floodplain Administrator at 407-971-5682 or e-mail at akortus@cityofoviedo.net.

Hurricane Preparedness Guide (LINK)

The City’s Stormwater staff serve the citizens of Oviedo by effectively managing, maintaining, protecting, and improving the public stormwater drainage system to prevent damage to life and property from storms, floods, and hurricanes. We also work to protect the water quality and safeguard our natural resources for future generations.

Flooding

The City of Oviedo can provide floodproofing advice for older homes built before current building code standards, or homes that have a higher flooding risk due to the proximity of special flood hazard areas or sensitive areas more prone to flooding. To inquire if a property is in a special flood hazard area or if an elevation certificate is available, please email Amanda Kortus, Stormwater Administrator.

The City of Oviedo is proactive in local watershed monitoring, such as monthly lake levels and water quality. For more information, please visit the Seminole County Water Atlas website.

ILLICIT DUMPING

Introducing anything other than water into the City’s storm system, ponds, or ditches is considered illicit dumping and subject to punitive action by law. Please report any illicit dumping to Code Enforcement at 407-971-5789. Provide pictures, if possible. You may remain anonymous if you so desire.  

Flood Hazard: Check Before You Buy

Flooding and other surface drainage problems can occur well away from the coast. If you're looking at a property, it's a good idea to check out the possible flood hazards before you buy. Here's why:

• The force of moving water or waves can destroy a building.
• Slow-moving floodwaters can knock people off their feet or float a car.
• Even standing water can float a building, collapse basement walls, or buckle a concrete floor.
• Water-soaked contents, such as carpeting, clothing, upholstered furniture, and mattresses, may have to be thrown away after a flood.
• Some items, such as photographs and heirlooms, may never be restored to their original condition.
• Floodwaters are not clean: floods carry mud, farm chemicals, road oil, and other noxious substances that cause health hazards.
• Flooded buildings breed mold and other problems if they are not repaired quickly and properly.
• The impact of a flood—cleaning up, making repairs, and the personal losses—can cause great stress to you, your family, and your finances.

Floodplain Regulations

The City of Oviedo regulates construction and development in the Special Flood Hazard Areas (SFHA) to ensure that buildings will be protected from flood damage. Filling and similar projects are prohibited in certain areas. Houses substantially damaged by fire, flood, or any other cause must be elevated to City Standards (2 feet above base flood elevation) when they are repaired. More information can be obtained from the Stormwater Administrator at 407-971-5682.

Check for a Flood Hazard: Before you commit yourself to buying property, do the following:

• Ask the City of Oviedo if the property is in a floodplain; if it has ever been flooded; what the flood depth, velocity, and warning time are; if it is subject to any other hazards; and what building or zoning regulations are in effect.
• Ask the real estate agent if the property is in a floodplain, if it has ever been flooded, and if it is subject to any other hazards, such as sewer backup or subsidence.
• Ask the seller and the neighbors if the property is in a floodplain, how long they have lived there, if the property has ever been flooded, and if it is subject to any other hazards.

NPDES - National Pollutant Discharge and Elimination System

Under the Clean Water Act of 1972 all counties and municipalities are required to have a permit to discharge stormwater drainage to Surface Waters of the State. Surface Waters of the State are defined as natural waterbodies protected and governed by local, state and federal agencies. The City of Oviedo was issued its first NPDES permit in 1997 as a co-permittee with Seminole County. The Florida Department of Environmental Protection (FDEP) governs the permit and all the regulations required for compliance includes but is not limited to:

• Identify Major Outfalls (mapping and inspections)
• Inventory the entire city’s storm system (mapping) including, treatment ponds, ditches, storm pipes, inlet boxes.
• Detect and eliminate non-stormwater discharges (enforcement of illicit discharges)
• Surface water sampling to ensure quality of recreational river and lakes.
• Inspections of stormwater treatment areas (ponds and ditches)
• Perform routine inspections to underground infrastructure (pipes, drains, culverts)
• Provide public outreach and educational materials
• Reduce pollutants and nutrients from the city stormwater runoff , by methods such as street sweeping and jet vacuuming pipes and drains.
• Evaluate and implement restoration plans for waterbodies with an adopted Total Maximum Daily Loading (TMDL)

TMDL

As part of the city’s NPDES program the city’s natural water bodies (Class III surface waters) are subject to a State and Federal process to ensure they are in good health. Any Class III surface waters that indicate elevated levels of nutrients is labeled impaired (unhealthy). Based on specific criteria, steps must be taken to reduce nutrients from entering the natural waterbody, this criteria is part of a reduction plan is called a Basin Management Action Plan. The pollutant reduction goals are called Total Maximum Daily Loads.

In February 2025, the following water bodies were included on the Comprehensive Verified Listing of Impaired Water Bodies by FDEP;

• Lake Charm – Impairment - Total Nitrogen, Total Phosphorus and Chlorophyll-a.
• Long Lake - Impairment – Total Nitrogen and Chlorophyll-a.
• Sweetwater Creek – Escherichia coli.

For viewing water quality results, you can visit the Seminole County Watershed Atlas at Water Quality Dashboard - Seminole.WaterAtlas.org

One of the largest contributors to water pollution is fertilizer, please help the City cut down on the use of all chemical fertilizers, if you have reclaim water it already has a nutrient value that greens your lawn. For planting landscaping that requires little to no fertilizer and is climate and wildlife friendly please visit Florida Friendly Landscaping at https://ffl.ifas.ufl.edu.

If you have more questions regarding the stormwater and NPDES Program please contact the Stormwater Administrator at 407-971-5682 or by e-mail to akortus@cityofoviedo.net
