Alamo, CA
Pavers in Alamo, CA
Alamo is unincorporated, so Contra Costa County, not a city, handles permits: building and grading through the County (County) and encroachment permits for work in the road right-of-way through County Public Works (Public Works). Projects here tend to be larger: pool decks, long driveways and big patios.
Large lots, bigger surfaces
Alamo's large lots mean bigger paved areas: pool surrounds, motor courts and long driveways. Size changes the math. A big area spreads fixed costs, but it also moves more water, and once a remodel creates or replaces 2,500 sq ft or more of impervious surface, the Contra Costa Clean Water Program's C.3 runoff measures apply. Pervious pavement, dispersing runoff to landscaping, rain barrels or cisterns, and bioretention are the accepted options (C.3 small projects guide).
Pool decks
Replacing a tired concrete deck is one of the most common requests. Light, textured surfaces stay cooler and grippier; HomeGuide notes travertine runs 20%–30% cooler than concrete in direct sun, and lists travertine decks at $13–$30+ per sq ft (HomeGuide). Plan the coping edge before the deck. Pool deck pavers.
Driveways at the road
Where a driveway meets a County road, the apron sits in the County right-of-way, and construction there needs a County encroachment permit (County Public Works). Private lanes and HOA roads have their own rules; ask before changing the entrance.

FAQ
Alamo questions
Who issues permits in Alamo?
Alamo is unincorporated, so Contra Costa County handles building and grading permits (County overview) and County Public Works issues encroachment permits for construction in the public right-of-way (County Public Works).
Is a permeable patio worth it on a big Alamo lot?
If you are converting lawn with EBMUD's rebate it is required: new patios and paths must be permeable. On large remodels that create or replace 2,500 sq ft or more of impervious surface, Contra Costa's C.3 runoff measures also come into play, and pervious pavement is one accepted option.
