Seller preparation

What Sienna buyers will ask, and what to have ready

1. Your section's MUD, the LID and the city

   Sienna has no single tax rate. Sections on HAR's tax tables pay Fort Bend County ($0.412 per $100, 2025), the drainage district ($0.01), Fort Bend ISD ($1.0569, 2025) and Sienna Parks and LID ($0.4125, 2025). Then the section's MUD is added: the developer lists MUDs 3, 4, 6, 7, 10 and 12 and a no-MUD section called the Woods, and FBCAD's 2024 table shows rates from $0.4075 to $1.05. HAR's tables show Shipman's Landing, Waters Lake and Sienna Acreage Estates also paying Missouri City ($0.570825, 2025). If the proposed Sienna MUD No. 3 annexation is approved, city taxes would start there in fall 2027. School districts exempt $140,000 of a homestead's value, and the seller's bill is not yours.

   • The MUD number and any city levy are on the FBCAD account.
   • Ask whether the MUD has new bonds authorized but not yet sold.

   What buyers will do: Pull the FBCAD account for the exact lot and total every unit's adopted rate before you compare Sienna homes.

   What to have ready: Your latest tax statement with its list of taxing units and your exemptions. Buyers know their own bill will be figured on their own value and exemptions, so a clear breakdown helps.

2. The levee district and the Brazos

   Sienna sits along the Brazos River behind the Sienna Plantation levee district (Fort Bend LID 14 on the county's river corridor list). During Hurricane Harvey in 2017, KHOU reported that officials found an eroded section on the Sienna Plantation levee as the Brazos crested; the river reached a record 55.19 feet at the Richmond gauge on Sept. 1, 2017. The National Weather Service lists street flooding on Sienna Parkway and McKeever Road at a 53-foot stage. Risk differs by section and lot.

   • Ask the seller for the elevation certificate, flood disclosure and any claims history.
   • Price flood insurance even outside the mapped high-risk zone.

   What buyers will do: Check the lot on FEMA's map and the county's levee and inundation maps, then get a flood insurance quote before you offer.

   What to have ready: Your seller’s disclosure flood answers, any elevation certificate, your flood insurance declarations page and records of any claim, repair or mitigation work.

3. Which association, and what it costs

   Non-gated homes belong to the Sienna Residential Association or Sienna Community Association; get the current assessment from the association or the resale certificate. Gated neighborhoods and townhomes add their own assessments (2022 schedule: $382 to $8,202 a year for gated sections, $1,800 a year for townhome units). The 2022 schedule also listed a $210 transfer fee, a $1,307 resale reserve capitalization fee and a 0.5% enhancement fee paid by the seller on resales. Exterior changes go through the Modifications Committee, and a certificate of compliance must be ordered through HomeWiseDocs before closing.

   • Current gated and resale fees come from the resale certificate, not the 2022 schedule.
   • Association office: Club Sienna, 9600 Scanlan Trace, 281-778-0778.

   What buyers will do: Ask for the resale certificate and the section's current assessment early in the option period.

   What to have ready: The management company’s contact, an early order for the resale certificate for every association on the lot, and approval letters for exterior changes.

Insurance and disclosures: buyers will price homeowners and flood insurance before they commit. Have your current declarations pages, any elevation certificate and any flood-claim history ready; Texas sellers also answer flooding questions on the seller’s disclosure notice (Texas Property Code §5.008).
