What Southpark is
The SOUTHPARK Specific Plan covers about 126 acres and was last amended by Ordinance 1619 on February 4, 2025. It calls for offices, commercial space and light industrial uses, and it allows up to 1,100 residential units shared across three of its six planning areas.
Planning areas D, E and F allow no residential use. Area D is limited to commercial uses such as discount, membership and home-improvement stores. The plan also names Talbert Avenue, Euclid Street and Slater Avenue as special landscaped streets and mentions the Santa Ana River in a setback rule.
The plan text we reviewed gives no written boundary description, so we do not state exact edges here. Use the streets above as a rough guide and confirm your address with the city.
Plumbing questions that come with commercial space
These are general points that apply to commercial buildings anywhere in the city.
Tenants and landlords
Your lease decides who pays for a repair. Read it before you call, and tell the property manager in writing so there is a record of when you reported the problem.
Offices and shops
Restrooms, break rooms and small water heaters are the usual plumbing in an office or store. Slow drains and running toilets are worth fixing early because they affect everyone in the space.
Food service tenants
A restaurant or food counter may need a grease interceptor. The city and the Orange County Sanitation District set the rules, so ask them before you plan the work.
Larger stores and warehouses
Big spaces can have many fixtures, floor drains and long drain runs. A scheduled inspection finds small problems before they stop the business.
Commercial plumbing question?
Call and give the street address and suite number.
Jobs worth planning for
Commercial plumbing covers the same trades as home plumbing at a larger scale. Each link goes to a full guide.
Water service and backflow
Commercial buildings often have water service and backflow equipment that needs attention. Start with the commercial plumbing guide.
Drains and sewer lines
A stopped main line can close a restroom or a whole suite. See sewer line cleaning and hydro jetting.
Hidden leaks
A leak in a ceiling or slab can run for weeks before anyone sees it. See leak detection for how plumbers find one.
Water heaters
Offices and shops rely on a heater for sinks and cleaning. See water heater repair and replacement.
Tenant, owner or property manager: who calls first
In a leased space, call the property manager first unless the lease says otherwise. The manager may already have a contractor, and a repair made without permission can cause a dispute.
Owners and managers can call us to ask about a repair, an inspection or a repeat problem. Give the street address and suite number, and say whether other tenants are affected.
Before you call
Commercial calls move faster when the details are ready.
Street address and suite
Give the full address, the suite number and the cross street.
Which fixtures
Say which restrooms, sinks or drains are affected and whether other suites share the line.
Who is responsible
Check the lease or ask the manager who handles plumbing, and who can approve work.
Access details
Note the hours the space is open and who can let a plumber in.
Map of the Southpark Area
The map is centered where Euclid Street and Talbert Avenue meet, two of the streets named in the plan. It is a locator and not a boundary.
Permits and inspections
Tenant improvements and water heater changes can need a permit. The Fountain Valley Building Division, at 10200 Slater Avenue and 714-593-4429, can tell you what applies to your project.
Ask about backflow protection and any sanitation district requirements at the same time, since commercial work can involve more than one agency.
Local note
The plan facts come from the SOUTHPARK Specific Plan on the City of Fountain Valley website, as amended by Ordinance 1619. A public encyclopedia article also describes Southpark as a commercial district near the Santa Ana River.
The plan does not describe individual buildings or their plumbing, so everything else on this page is general guidance.

Common Questions
Mainly no. The city plan treats it as a mixed-use district for offices, commercial space and light industrial uses. The plan allows up to 1,100 residential units in three of its six planning areas, and three areas allow none.
Your lease decides, so read it first. We cannot say who is responsible, but the plumber can explain what is wrong and what the repair involves.
