Wash Water & Stormwater Regulation — Florida
Florida Department of Environmental Protection (FDEP) — NPDES Stormwater Program
FDEP administers Florida’s National Pollutant Discharge Elimination System (NPDES) stormwater permitting program, authorized by EPA in October 2000 under Section 403.0885 of the Florida Statutes. This program governs what can legally enter a storm drain or waterway, including runoff from pressure washing. Wash water carrying detergents, surfactants, or cleaning chemicals is treated differently under this program than plain rainwater runoff.
FDEP — NPDES Stormwater Program →FDEP — Mobile Wash Water Best Management Practices
FDEP’s guidance on mobile washing operations (including pressure washing) explains when wash water discharge requires a permit, and the best management practices — such as minimizing water use and avoiding repeated discharge to the same landscaped area — that responsible operators follow to avoid pollution of state waters.
FDEP — Mobile Washing BMPs (PDF) →City of Jacksonville — Local Stormwater Authority
City of Jacksonville Chapter 754 — Stormwater Management Utility Code
The consolidated City of Jacksonville’s own ordinance governing what may legally discharge into the city’s Municipal Separate Storm Sewer System (MS4). The code explicitly prohibits illicit discharges — including commercial wastes and chemical runoff — into storm drains anywhere in Duval County, and requires anyone with an NPDES permit authorizing MS4 discharge to register it with the City Engineer’s Office. This is the local authority behind our commitment to responsible water use and runoff practices on every job — see Our Process for how this plays out on-site.

Severe Weather & Hurricane Data — Federal Sources
NOAA National Hurricane Center — Atlantic Hurricane Season
The federal authority setting the official Atlantic hurricane season dates: June 1 through November 30 each year, a window chosen because it accounts for the overwhelming majority of Atlantic tropical storm and hurricane activity based on long-term NOAA storm climatology. This is our source for every hurricane-season timing reference across our Jacksonville pre- and post-storm cleaning content.
NOAA — Tropical Cyclone Climatology →National Weather Service — Jacksonville Forecast Office
The NWS office responsible for weather forecasting, climate normals, and severe weather warnings across Northeast Florida, including Duval, Clay, St. Johns, and Nassau counties. NWS climate data for Jacksonville is the basis for our references to the area’s average humidity levels and subtropical climate patterns that drive mold and algae growth on exterior surfaces — see our guide on why Jacksonville’s humidity turns driveways green fast for the full picture.
National Weather Service — Jacksonville, FL Office →Mold, Fungus & Landscape Science — University Extension Sources
University of Florida IFAS Extension — Artillery Fungus in Florida Landscapes
UF/IFAS Extension’s published guidance on artillery fungus (Sphaerobolus stellatus) in Florida specifically notes that spore masses can be ejected up to 20 feet wide and 15 feet high, that the fungus is more commonly found on the north side of a residence due to its preference for cooler temperatures, and that hardwood mulch during Florida’s wet season is its primary host. This is our source for every claim we make in our artillery fungus guide about behavior, distance, and mulch-based prevention on Jacksonville properties.
UF/IFAS Extension — Artillery Fungus, Small But Mighty →University of Delaware Cooperative Extension — Artillery Fungus and Mulch
Independent university extension research confirming artillery fungus fruiting body size (approximately one-tenth of an inch), its cup-shaped structure holding a single spore mass (peridiole), and its light-seeking (phototropic) spore-ejection behavior. Used alongside UF/IFAS data to cross-verify the biological mechanics we describe.

Mold Growth & Moisture — Environmental Health Data
U.S. Environmental Protection Agency (EPA) — Mold, Moisture, and Your Home
EPA’s published guidance on indoor mold and moisture control establishes that mold can begin growing on a damp surface within roughly 24 to 48 hours of water exposure. This is our source for the moisture-intrusion timelines referenced in our guidance on DIY pressure washing risks, particularly around water forced behind siding or into wall cavities.
EPA — A Brief Guide to Mold, Moisture, and Your Home →Population & Local Housing Context
U.S. Census Bureau — QuickFacts, Jacksonville City, Florida
The federal source for Jacksonville’s population and housing stock data, drawn from the American Community Survey and Decennial Census. Referenced for general population and housing-age context across our neighborhood-specific service area pages, including older housing stock common in historic areas like Riverside & Avondale and San Marco.
U.S. Census Bureau — Jacksonville, FL QuickFacts →Our Data Commitment
We don’t publish a regulation, a climate figure, or a scientific claim without a named source behind it. Every stormwater statement traces to FDEP or the City of Jacksonville’s own ordinance. Every hurricane-season date traces to NOAA. Every fungus or mold claim traces to a university extension program or the EPA. If a source updates — a code is amended, a climate normal is revised, new research is published — we update our content to match it, not the other way around.
Frequently Asked Questions — Resources & Data
Who regulates pressure washing wash water runoff in Jacksonville?
The Florida Department of Environmental Protection (FDEP) administers the state’s NPDES stormwater permitting program, and the City of Jacksonville enforces its own Chapter 754 Stormwater Management Utility Code, which prohibits illicit discharges — including chemical-laden wash water — into the city’s storm drain system.
Is Jacksonville really in an active hurricane zone?
Yes. Jacksonville sits within the Atlantic hurricane season’s coverage area, which NOAA’s National Hurricane Center defines as running from June 1 through November 30 each year, based on decades of Atlantic storm climatology.
Where does the artillery fungus distance and behavior information come from?
Primarily from University of Florida IFAS Extension’s published research specific to Florida landscapes, cross-referenced with University of Delaware Cooperative Extension data on the fungus’s biological mechanics.
How quickly can mold actually start growing after water damage?
According to EPA guidance on mold and moisture control, mold can begin growing on a damp surface within approximately 24 to 48 hours, which is why moisture intrusion from improper pressure washing technique is treated as a real, time-sensitive risk rather than a minor concern.
