Water and the sink line in Tempe

Tempe produces most of its potable water at two conventional surface-water treatment plants - the Johnny G. Martinez Treatment Plant and the South Tempe Water Treatment Plant - fed by SRP water (Salt and Verde river watersheds, diverted into SRP canals at Granite Reef Dam) and CAP Colorado River water, with groundwater wells supplementing supply (https://www.tempe.gov/government/public-works/water/water-quality/faq-water - HTTP 403 to our datacentre IP, bot protection on the correct city source). The city notes that the Salt River source is characteristically higher in total dissolved solids and chlorides while the Verde River source is higher in hardness compounds (CaCO3), so water character shifts with the seasonal blend and year-to-year runoff - worth knowing before specifying stone that will be regularly rinsed outdoors.

Soil, drainage and the base

Tempe sampling (USDA-NRCS Soil Data Access) returns a mix of Avondale clay loam, Gilman loam, Laveen loam and Rillito gravelly loam - calcareous Torrifluvents (Avondale, Gilman) sitting alongside calcic Haplocalcids (Laveen, Rillito) (https://soilseries.sc.egov.usda.gov/OSD_Docs/A/AVONDALE.html and https://soilseries.sc.egov.usda.gov/OSD_Docs/G/GILMAN.html, both HTTP 200). All four are well drained to somewhat excessively drained, which is good news for drainage and means the cemented calcic layer, where it is present, is what stops a trench rather than the topsoil.

What the local stock means here

Tempe sits in Maricopa County, served by City of Tempe Water Utilities. Phoenix is a 110 F-plus summer metro with an extreme-UV load and a storm-peaked monsoon. The NWS Phoenix forecast office publishes daily probability tiers for the metro at 100, 105, 110 and 120 F and keeps a running yearly count of Phoenix days at or above 110 F (https://www.weather.gov/psr/heat, HTTP 200), and the monsoon season runs through September 30, bringing the dust storms (wind gusts 40-60 mph) and thunderstorms NWS calls the most dangerous weather period of the Southwest year (https://www.weather.gov/psr/MonsoonSafety, HTTP 200). Sun load is the second half of the exposure: on EPA's UV Index scale everything at 8 and above is 'very high to extreme', where EPA advises extra protection even outside of peak hours (https://www.epa.gov/sunsafety/uv-index-scale-0, HTTP 200). The practical consequences for an outdoor kitchen are that shade and heat/UV tolerance drive material selection rather than looks, and that the usable season inverts: roughly October through May is the comfortable cooking season, while June through September is the survival season for both people and finishes.

What to check in this town

Tempe bills water, sewer and solid waste on one monthly municipal utility bill, and its 24/7 water outage or main break line is 480-350-2837 (https://www.tempe.gov/government/public-works/water, HTTP 403 to our IP).
Permits: Inside Phoenix, residential outdoor-kitchen work is permitted by the City of Phoenix Planning & Development Department (PDD), which issues residential building, gas, plumbing, mechanical and electrical permits, runs plan review and inspects, from the permit centre at 200 W. Washington St. (https://www.phoenix.gov/administration/departments/pdd/residential-building.html, HTTP 200). PDD's own guide puts detached structures without utilities of 200 sq ft or less and uncovered patio slabs or decks less than 30 inches above grade outside permit scope, while attached patio covers or ramadas, gas lines and gas-fired equipment, electrical circuits, sinks/sewer/water lines and change-of-drainage conditions all require one (How to Obtain a Residential Permit, https://www.phoenix.gov/pddsite/Documents/TRT/dsd_trt_pdf_00823.pdf, HTTP 200). Properties in unincorporated Maricopa County are permitted by the county rather than the city (https://www.maricopa.gov/1385/Permit-Application, HTTP 200).
Call 811 before anyone breaks ground for the island footings, the gas run or a water line — free locate, several days' notice.
In Phoenix, a new or extended natural-gas line feeding an exterior gas appliance off the natural-gas meter is listed by PDD as an over-the-counter 'Express Permit', while every propane installation must be routed through Residential Plan Review staff (PDD, Residential Over the Counter Permits Guideline TRT/DOC/00366, rev. 06/17, https://www.phoenix.gov/pddsite/Documents/TRT/dsd_trt_pdf_00366.pdf, HTTP 200). Buried fuel-gas piping must meet the adopted IFGC: minimum 12 inches of earth cover for insulated ferrous gas pipe and 18 inches for polyethylene (PE) gas pipe, with an insulated 18 AWG tracer wire run adjacent to the PE and terminated above ground at each end, and no gas piping in or on the ground underneath any building or structure (Maricopa County detail DD-5001-01, which also sets LP-gas container separations - portable containers of 5 lb/gallons or less used for outdoor appliances such as barbecue grills are exempt from the separation chart) (https://www.maricopa.gov/6487/Liquefied-Petroleum-Gas-Containers-and-F, HTTP 200). Two easement points before the trench opens: check the recorded plat and title report for rear/side lot-line utility easements and canal rights-of-way (SRP canal and CAP turnouts are common in the Valley, and an HOA approval never overrides a utility easement), and have underground facilities located free of charge through the 811 one-call service - in Arizona, Arizona 811 - before digging (https://call811.com/, HTTP 200). One more Valley rule worth knowing: Maricopa County's residential burning restrictions (Ordinance P-26 and Rule 314) exempt any device that burns only natural gas, propane or LP-gas, so a gas fire feature or grill is not affected by no-burn days the way a wood-burning chiminea or fire pit is (https://www.maricopa.gov/7032/Rule-314---Outdoor-Fires-and-Commercial-, HTTP 200).
HOA approval is the most commonly skipped step on Valley outdoor kitchens and it is close to universal in the master-planned neighbourhoods. Before construction, get the CC&R architectural submittal - plot plan, elevations, material and colour schedule, and often the gas-fire-feature detail - approved in writing. Arizona regulates this under the Planned Communities Act (A.R.S. Title 33, Chapter 16): § 33-1817(B) requires the design or architectural committee to include at least one board member serving as chairperson and provides that approval of a construction project's architectural designs and plans 'shall not unreasonably be withheld' (https://www.azleg.gov/ars/33/01817.htm, HTTP 200), and § 33-1803 requires notice and an opportunity to be heard before penalties are imposed and caps late-payment charges (https://www.azleg.gov/ars/33/01803.htm, HTTP 200). Check the recorded plat for what the association actually owns or controls - walls, view fences, common-area landscape strips and easements - because the association cannot approve construction that a utility easement forbids.
