None of the three is better than the others; each fits a different set of priorities. The Energy Corridor puts you closest to the office towers on Eldridge Parkway, in 1970s and 1980s homes, townhomes and apartments, much of it inside the City of Houston and at the edge of two federal flood-control reservoirs. Memorial gives you older homes on large wooded lots, either in one of six independent Villages with their own zoning and police arrangements or in Memorial West inside Houston, downstream on Buffalo Bayou. Katy gives you new construction in master-planned communities about 11 freeway miles west, usually with a utility district on the tax bill.

This guide is written by Energy Realty, a west Houston brokerage with offices in the Energy Corridor, at 1111 Eldridge Parkway, and in Katy, at 23033 Grand Circle Boulevard. Our agents lease, buy and sell in all three areas, and every rate below carries its source and year.

First, what each name actually covers

The Energy Corridor is a management district, legally Harris County Improvement District No. 4, operating since 2001. It describes itself as more than 2,000 acres along Interstate 10 from Kirkwood Road to west of Barker Cypress Road, extending south along Eldridge Parkway to south of Briar Forest Drive. Much of it lies inside Houston’s city limits. The homes are in the subdivisions, townhomes and apartments around it, which our Energy Corridor guide covers by name.

Memorial is two kinds of place. The six Memorial Villages (Hunters Creek, Piney Point, Bunker Hill, Hedwig, Hilshire and Spring Valley) are separate cities that incorporated in 1954 and 1955. Memorial West, to their west, lies in the City of Houston’s Super Neighborhood 16, which the City names Memorial and bounds by I-10, the Villages, Buffalo Bayou and, approximately, State Highway 6. The management district begins farther east, at Kirkwood Road, and the City’s own description of Super Neighborhood 16 places Energy Corridor office centers along I-10 in its northern portion, so the two overlap along I-10 between Kirkwood and Highway 6. Our own guides list Nottingham Forest and Memorial Thicket under both names.

Katy is also two places. The City of Katy incorporated in 1945 where Harris, Fort Bend and Waller counties meet, and had an estimated 28,373 residents on July 1, 2025, in the Census Bureau’s Vintage 2025 estimates, on about 15.3 square miles. The Katy area is the far larger territory of master-planned communities with Katy mailing addresses in ZIP codes 77449, 77450, 77493 and 77494, mostly unincorporated land spanning portions of Fort Bend, Harris and Waller counties.

The three side by side

We print no home prices, and our area guides print none either: price is set street by street, and any single number is stale within a month.

How the tax bills compare: three worked examples

Texas has no state income tax; Article VIII, Section 24-a of the state constitution prohibits one. A property tax bill is the sum of every taxing unit whose boundary contains the parcel, each with a rate per $100 of taxable value. Every Harris County address pays five county-level lines and a school district, and usually a city, a utility district or both.

The tables use 2025 adopted rates, the latest year in which every unit in each column has published a rate. They are sums before exemptions and exclude emergency services, community college and water authority lines, so treat each total as a floor. For a homestead, the school exemption is $140,000 under Tax Code Section 11.13(b), and appraised value cannot rise more than 10 percent a year under Section 23.23. Our MUD and property tax guide goes deeper.

Energy Corridor and Memorial: Harris County addresses inside a city

The five Harris lines are the county at 0.380960, flood control at 0.049660, the port at 0.005900, Harris Health at 0.187610 and the Department of Education at 0.004798. In the Energy Corridor, which the district says all three school districts serve, the school line swings by about 0.24 per $100. Inside Houston there is usually no utility district, though exceptions exist where a district predates annexation. The Energy Corridor District itself appears on the appraisal district’s 2025 list as HC ID 004 at 0.100000, but state law bars a management district from assessing single-family detached homes, duplexes, triplexes and fourplexes unless its voters approve the levy (Local Government Code Section 375.161, applied to this district by Special District Local Laws Code Section 3814.006). For other property, the parcel’s jurisdiction list shows whether it applies.

In Memorial, living in a Village does not mean paying no city tax; it means paying that Village’s tax. The six 2025 Village rates ran from 0.205164 in Hunters Creek to 0.529226 in Hilshire, slightly above Houston’s 0.519190, so the choice of Village moves the total by about 0.32 per $100. The Memorial Villages Water Authority, whose board seats belong to Hedwig, Hunters Creek and Piney Point Villages plus one at-large member, levied 0.022920 for 2025; a parcel inside it takes the Hunters Creek example to about 1.88. Bunker Hill Village runs its own water service, and the parcel’s jurisdiction list shows whether the authority applies.

Katy: inside the city and outside it, on both sides of the county line

Fort Bend County’s line is 0.412000 plus 0.010000 for its drainage district; the Harris side carries the same five lines as above. The two utility districts are the examples our MUD guide uses, and both listed no debt-service rate for 2025, which is what a mature district looks like. Swap in a young one and the picture changes. A district still paying off its construction bonds can levy 1.00 or more per $100. At a 1.00 district rate, the unincorporated Harris column rises to about 2.75, and an unincorporated Fort Bend stack without a drainage district to about 2.54. Texas Water Code Section 49.452 requires the seller to give you the district’s rate and bonds in writing before you sign a binding contract.

What 2026 has changed so far

The four county-controlled Harris lines rise from 0.624130 to 0.671470, about 0.047 per $100, on every Harris County address. Spring Branch ISD’s net increase of 3.32 cents, driven by its 2025 bond program, reaches every address in that district. The City of Houston, Houston ISD, the City of Katy, Fort Bend County and our example utility districts had not posted a 2026 rate we could read, so full 2026 columns are not yet possible.

Flood setting, area by area

No area here can be described as low risk as a whole. The Harris County Flood Control District counted 154,170 homes flooded in Harris County in Hurricane Harvey in August 2017, and 68 percent were outside the mapped 100-year floodplain. Our flood zone guide covers each step.

Energy Corridor: beside the reservoirs

Addicks Reservoir lies north of I-10 and Barker Reservoir south of it, at the corridor’s western edge, both federal dry dams run by the Army Corps of Engineers. The government bought the land behind Addicks up to about 103 feet of elevation and behind Barker up to about 95 feet. On August 30, 2017 the pools crested at a record 109.1 feet in Addicks and 101.6 feet in Barker, beyond the government’s land, and the federal trial’s test properties included the Lakes on Eldridge subdivision in the Addicks flood pool. The Court of Federal Claims found a taking in 2019, and the Federal Circuit affirmed liability in December 2025.

Memorial: downstream on Buffalo Bayou

The Flood Control District’s Harvey report records record flooding at every bridge crossing along Buffalo Bayou. At Piney Point Drive the bayou peaked at 15,000 cubic feet per second, against a prior record of 7,990 set in April 2009, with levels influenced by the Corps’ emergency releases. The report counts 190 flooded homes in Hunters Creek Village, 170 in Piney Point Village and 20 in Bunker Hill Village. Inside Houston, the 2018 Chapter 19 changes presented by Houston Public Works put new construction in the 500-year floodplain at the 500-year elevation plus 2 feet.

Katy: upstream of Barker

The Harvey report records record flooding along upper Buffalo Bayou and Cane Island Branch through the City of Katy to Barker Reservoir, and 630 flooded homes in the city’s Harris County portion. It adds that about 15,000 more homes flooded where its watersheds reach into seven neighboring counties, with one of the largest concentrations in Fort Bend County in the Barker flood pool. The trial’s Barker test properties included Kelliwood Manor Lane and four other Katy streets. Fort Bend County began adding plat warnings in the early 1990s that a subdivision is subject to controlled inundation from Barker Reservoir, so read the plat. In unincorporated Harris County, the lowest habitable floor of a new home in the regulated floodplain must sit at least 24 inches above the 500-year flood elevation.

The commute to the Energy Corridor

The district says more than 60,000 people commute into it daily; living inside it can keep the commute on local streets such as Eldridge Parkway, Dairy Ashford and Memorial Drive. From Memorial, I-10 and Memorial Drive both run west through Memorial West into the corridor, and Terry Hershey Park’s 11.05 miles of trail follow Buffalo Bayou along that stretch.

From Katy, I-10 is the direct route. Its exit numbers are mile-based: Katy Fort Bend Road is exit 742 and Eldridge Parkway exit 753, about 11 freeway miles, and the drive depends heavily on the hour. The Grand Parkway, SH 99, is the north-south bypass on the Katy side; TxDOT’s 2026 toll at its Colonial Parkway ramps is 56 cents with a toll tag. The Westpark Tollway runs a few miles south. If one job is downtown, the I-45 exit is 768, about 15 miles from Eldridge and 26 from Katy, and METRO runs park and ride from Addicks and from two Katy lots. Drive the route at 7:30 a.m. and 5:15 p.m. from the actual address before you commit.

Choose the Energy Corridor if…

• The shortest drive to an office on Eldridge Parkway or Dairy Ashford is worth more than a newer house.
• You want to lease first. The corridor’s apartments, townhomes and furnished corporate housing put a lease close to the office, and our relocation guide recommends leasing first for a two- or three-year assignment.
• Parkland matters daily: Terry Hershey Park covers 496 acres, and George Bush Park, 7,800 acres inside Barker Reservoir, sits just west.
• You are comfortable with a 1970s or 1980s house and a foundation report, since parts of the corridor sit on shrink-swell clay.
• You want City of Houston services and, usually, no utility district line.

What you accept: reservoir-edge flood homework, I-10 traffic for any job outside the corridor, and a market that moves with the energy industry’s hiring cycle.

Choose Memorial if…

• An established lot and mature trees matter more than new construction. Hunters Creek Village describes itself as about 1,460 homes on two square miles; Bunker Hill Village as a city of 1,250 homes.
• You want a small city’s own rules. Hunters Creek Village’s zoning chapter, for example, bars building on any lot under 22,500 square feet, and its Planning and Zoning Commission hears changes to it.
• You plan to build or rebuild; the Villages run on a teardown-and-rebuild cycle in which the lot is often the asset.
• You want Memorial City Mall, CityCentre and Memorial Hermann Memorial City Medical Center close by.

What you accept: a Village tax line above or below Houston’s, and a bayou flood history that differs street by street. Our Memorial guide covers each Village.

Choose Katy if…

• You want new construction, a builder’s warranty and your own finishes. Bring your own agent to the first model-home visit; the sales representative works for the builder.
• Builder incentives matter to you. They often move with interest rates, so compare offers in writing.
• You are comfortable reading a utility district notice before you sign.
• You want the Katy area’s retail cluster, including LaCenterra at Cinco Ranch and the Katy Boardwalk District.

What you accept: the mailing address does not tell you the county, city or tax stack, and the Barker flood pool reaches subdivisions that do not look like a floodplain on a dry day. Our Katy guide covers the communities.
