A buyer touring The Reserve at St. Charles Bay usually asks one question about ongoing costs: what are the HOA dues. It's a fair question, and it has an answer, sort of. Recent listings inside the community have shown quarterly dues in the neighborhood of $1,950 to $2,070 for certain homes, while at least one owner has reported paying closer to $1,200 a quarter. Both numbers are real. Neither is wrong. And neither is the full bill.
The Reserve sits inside its own small unit of Texas government, a special water district with an elected board, its own tax roll, and its own aging pipes. That district doesn't show up on the community's amenities page. It shows up on your property tax statement, and lately, in a notice addressed directly to Reserve residents about the water coming out of their own faucets.
The Dues Range Isn't a Typo, It's a Product Line
The Reserve isn't one house type sold at one price point. The community offers turnkey Villas, generally in the 1,600-square-foot cottage-style range, alongside a Luxury Collection of custom single-family homes that can run past 2,700 square feet with private yards and private docks to maintain. Villa dues typically bundle in landscaping and exterior maintenance. Custom-home owners on the Luxury Collection side carry more of that upkeep themselves, which is one reason the quarterly number moves around depending on which product a listing describes.
That's useful context if you're cross-shopping. A $1,200 quarterly figure and a $2,070 quarterly figure aren't two different eras of pricing at the same community. They're two different ownership structures, and asking which one applies to the specific address you're considering is a better question than asking for "the" HOA fee. The management company on record for the association is FirstService Residential, and a written fee schedule tied to your exact lot and product type is the only number worth budgeting against.
The Government You Didn't Know You Were Joining
Here's the part that doesn't show up on a listing sheet at all. The Reserve sits within the Lamar Improvement District, a special district created by an act of the Texas Legislature in 2007. It covers 411.617 acres across two separate tracts of land on the Lamar Peninsula, one of which borders Goose Island State Park and St. Charles Bay, which is exactly where The Reserve sits. The district isn't part of the City of Rockport or any city's extraterritorial jurisdiction. It has its own board, currently five seats, and that board meets the third Thursday of most months at the Lamar Volunteer Fire Department to handle the district's business, including its own water utility.
The Aransas County Appraisal District lists Lamar Improvement District as a separate taxing entity, alongside the City of Rockport, Aransas County MUD #1, and the local school districts. That means a Reserve property tax bill can include a line item most buyers moving from a standard subdivision have never seen before. And in 2024, the district issued new unlimited tax bonds, a sign it's still funding infrastructure rather than winding down its obligations.
None of this is a red flag by itself. Plenty of Texas coastal communities sit inside special districts. It's a fact that changes how you should read the dues sheet: the HOA fee and the district's tax rate are two separate bills from two separate governments, and only one of them is negotiable through the developer's sales office.
What Happens When a Small Water System Has a Bad Month
Special districts are only as reliable as the infrastructure they run, and Lamar Improvement District's water utility has had a rough stretch worth knowing about before you close. In September 2025, the Texas Commission on Environmental Quality required the district's public water system to issue a boil water notice to its customers, later lifted once lab results confirmed the water no longer needed boiling. Around the same period, the district's wholesale water provider had a main well pump go down, pushing Lamar Improvement District into what it called Stage 5, its emergency water shortage tier, which barred all landscape irrigation until the wholesale provider could truck in water and lean on interconnections with neighboring systems.
More recently, the district posted a notice specifically to homeowners inside The Reserve about the condition of the pipes themselves. In the district's own words:
"Residents of The Reserve, recent tests have confirmed concerns about corrosion in our water system."
The notice cites an analysis from the engineering firm Thornton, Musso & Bellemin, Inc. identifying low pH and high chloride levels as contributing factors, and states the district is exploring proactive measures while maintaining the water remains safe to use. That's a small, transparent utility doing what it's supposed to do when it finds a problem. It's also a useful data point for a buyer weighing a $2,070 quarterly HOA payment against a separate tax bill and a water system serving a community with a couple hundred residents. Small systems can be nimble. They can also be stretched thin faster than a municipal utility with a much larger customer base and reserve capacity.
The Exclusivity Pitch Met the Rental Market
The Reserve's marketing has long leaned on privacy and low density, a place for a family to have the water to themselves. That pitch has shifted in practice. A homeowner review posted publicly states the HOA now permits short-term renters, a change from what the reviewer understood the rules to be when they bought. That's consistent with what's visible on the ground: professionally managed vacation rentals inside the gates through Vacasa, with named properties like "No Time to Worry" and "Grateful and Gracious," and through Homes & Villas by Marriott Bonvoy, listing units such as "Innisfree" and "Reserve Lane Retreat."
For a lifestyle buyer who wants quiet, that matters. The neighbor's driveway may have a rotating cast of weekend guests rather than a familiar face. For an investor evaluating STR income potential, it matters differently and more favorably, since active third-party management already exists inside the community and rental permissibility isn't purely theoretical. Either way, the rule as marketed at launch and the rule as currently enforced aren't necessarily the same rule, which is exactly the kind of thing a CC&R review should confirm rather than assume.
What To Actually Request Before You Write an Offer
Given all of this, the standard advice to "get the HOA packet" undersells what you actually need here. Before an offer at The Reserve, ask for:
- The current written fee schedule for the specific product type and lot, not a community-wide average
- The most recent resale certificate, which will show any special assessments tied to the water system work
- The HOA's current written rental policy, since practice has moved past the original marketing
- Confirmation from the title company on which taxing entities appear on that specific parcel's bill, including the Lamar Improvement District rate
That last item is the one most out-of-area buyers skip, because they're used to a single property tax line and a single HOA line. At The Reserve, the real carrying cost is the sum of both governments, not just the one with the nicer website.
FAQ
Is the Lamar Improvement District tax separate from my Aransas County property tax bill? Yes. The district is its own taxing entity, distinct from Aransas County, the City of Rockport, and the local school district, and it appears as its own line on the appraisal district's list of taxing entities for parcels within its boundaries.
Does the HOA fee include water service? Water is delivered through the Lamar Improvement District's utility, operated under contract, not bundled into the HOA's landscaping and amenity dues. Confirm current utility rates separately from the HOA fee schedule.
Can I still buy a custom homesite at The Reserve, or is it built out? The community has continued to market both a Villas product and a Luxury Collection of custom single-family plans and homesites, so availability depends on current inventory rather than a fixed cutoff.
