Gutters in Sea Ranch Lakes, FL
In a 10-year five-minute downpour, rain falls in Sea Ranch Lakes at 11.1 inches an hour, and a 100-year burst reaches 16.1. Gutters that handle a light shower can overflow in one of these bursts. Sizing and downspout placement matter more here than most people assume.

Sizing the system
How gutter size depends on rain intensity here
Gutter capacity is set by the flow from the roof, which is driven by short, heavy rain. The plumbing code sizes horizontal gutters from the roof surface flow rate, and its capacity table runs from 4-inch to 8-inch half-round profiles. In Sea Ranch Lakes the design rain is the burst, not the daily total.

Going from a 5-inch to a 6-inch half-round gutter at the same slope lifts capacity by about 49 percent, from 74 to 110 gallons per minute. That step matters most on the roof sections that drain into the longest runs. Downspouts must match the gutter, and a 2-by-2-inch leader carries only 30 gallons per minute.
- Measure the roof area that drains to each gutter run.
- Check slope, since 1/8 inch per foot is the table basis here.
- Match leader size to the gutter, not the other way around.
- Count any wall above the roof that sheds rain onto it.
Keeping water off the foundation
Downspout discharge and where the water goes
The building code requires each downspout to end at least 1 foot out from the wall, whether through buried pipe, a tail extension or a splash block. Water that lands at the foundation of a Sea Ranch Lakes home can work toward the slab over a 96.8 percent owner-occupied housing stock built mostly before 1980.
Many of these homes sit on lots near the two lakes, where ground drains toward low spots. Confirm the discharge route with the Village of Sea Ranch Lakes permit office before you change a downspout.
Broward County normal rainfall is 60.95 inches a year at Fort Lauderdale-Hollywood International Airport, and 71.9 percent of it falls from May through October. Downspout runs should be checked before that wet season starts.
Keeping gutters clear
Leaves, trees and cleaning schedule
Live oaks drop leaves and fruit that become a litter problem in gutters, and oaks and pines are major pollen producers from January to June. Pine needles peak from September through November. Gutter cleaning should follow those seasons.
One insurer's guidance is to clean gutters at least twice a year, and more often under overhanging trees or during frequent storms. Water that backs up in clogged gutters can reach fascia, soffit and foundation edges. Ask your insurer or agent what maintenance your policy expects.
Rain on your roof
Preset: 9.61 inches, the 10-year 24-hour rain (NOAA Atlas 14 at Sea Ranch Lakes).
11,974 gallons run off that roof, all of it toward the gutters and downspouts.
Math: square feet × inches × 0.623 gallons.

Do gutters need downspouts on my house in Sea Ranch Lakes?
Yes, when eaves project less than 6 inches, the Florida Building Code requires gutters with downspouts, except at gable end rakes or where a roof sits above another roof. Each downspout must end at least 1 foot out from the wall. In Sea Ranch Lakes, where 80.0 percent of housing units were built before 1980, check your eave depth and permit file before making changes.

How often should I clean gutters near oak trees in Sea Ranch Lakes?
Plan on two cleanings a year at minimum, with extra passes if a canopy hangs over the roof. Live oak leaves and fruit make litter, and pine needles peak from September through November. In Sea Ranch Lakes, where 94.1 percent of housing units are single-family detached homes, a gutter run under a canopy collects debris fastest. Cleaning after the spring pollen season and before the June to September storm season is a sensible rhythm.
