Post-Harvey Frequently Asked Questions

1. Why don’t LID 15 and LID 19 operate as one LID? Why the separation?

LID 15 and LID 19 were created at separate times.  Although they serve the same community, due to the timing related to federal approval of floodplain reclamation plans and wetlands mitigation, it was determined the two districts should not be combined.

2. Why can’t we stop LID 15 from dumping water into our LID 19 area?

LID 19 and portions of LID 15 share detention and drainage facilities.  Other than the natural topographic separation that separates the Alcorn Bayou watershed (LID 15) from the Steep Bank Creek watershed (LID 19 and part of LID 15), there is no physical separation between the two districts.  LID 19 does not have the authority to restrict flows from LID 15 (or any other property) to the extent post-development flows are shown not to exceed pre-development flows.

3. Why can’t we pump the Riverstone lakes dry in anticipation of a rain event?

Without the pressure from the lake water, the bulkheads would potentially fail and fall into the lake causing damage/erosion to the area surrounding the lake.  Ensuing property damage could occur as a result.

4. How much pump capacity do we have now?

In the Steep Bank Creek watershed there is 80,000 gallons per minute of total permanent pumping capacity at the pump station (60,000 gallons per minute plus 20,000 gallons per minute as a spare pump).  In addition, LID 19 recently purchased trailer mounted pumps to provide an additional 81,000 gallons per minute of capacity.  Total pumping capacity (utilizing the spare pump and temporary pumps) is 161,000 gallons per minute.

5. How much pump capacity do we need to Harvey-proof our LID 19 houses?

Detailed modeling is required to determine the pumping capacity.  That modeling is currently underway.  The scale of additional pumping capacity required to prevent structural flooding during an event similar to Harvey would be an additional 4 to 5 times more than the fixed pumping capacity currently available in the watershed. Generally speaking, permanent facilities require approximately 6 to 9 months for design and regulatory approvals and an additional 18 months for construction.

6. Do we own the temporary pumps that are now at the pump station?

Currently, the temporary pumps are owned by LID 19.  Beneficial ownership may extend to LID 15, subject to LID 15’s financial contribution towards its appropriate share of costs.

7. Will our taxes increase to pay for the temporary pumps?

The LID 19 Board has determined to pay for the temporary pumps from available funds on hand.  At this time, the LID 19 Board does not foresee a need to raise LID 19 tax rates to pay for the temporary pumps.

8. How will we be notified in the event of an evacuation?

As soon as LID 19 is made aware of any evacuation order from Fort Bend County, information will be posted on LID 19’s website and emergency text/voicemail/email will be distributed to anyone who has registered to receive notices.  If you are interested in signing up for emergency notices, please click here.

9. Can we fire any consultant that we have that has not met expectations?

Yes.  Except in rare instances, most consultants/professionals engaged by LID 19 can be terminated with or without cause upon 30 days’ notice.

10. When will the third-party remediation recommendations be available? How long before they are implemented?

Phase 1 of the Third-Party Engineering Review is posted here.  Phase 2 and 3 are anticipated before the end of 2018.

11. Why doesn’t LID 15 pay for LID 19 improvements?

LID 15 pays for its pro rata share of drainage improvements based on their relative share of the total acreage within the Steep Bank Creek watershed.  LID 15 paid for 54.4% of engineering and construction costs for the Steep Bank Creek pump station, and continues to pay 54.4% of ongoing maintenance costs.

12. I’m having trouble signing up for emergency notices.  Please help.

Currently, verification for LID 19’s emergency notices is based on ownership records that are intended to be updated monthly from the Fort Bend Central Appraisal District.  At this time, we have identified delays that have affected some residents’ ability to sign up to receive notices.  If this happens to you or you have other problems signing up, please select the Help link or Contact link located at, or send an email to You may also request that Classic Messaging mail a registration form directly to you.  The Board will continue to work with Classic Messaging to improve this issue.

13. Why does the LID own and maintain parks?

In an effort to incentivize the development of public parks and recreational facilities for the public benefit, Texas law allows developers to build and finance parks and recreational facilities for water districts, including MUDs and LIDs. To protect the LID taxpayer from potential abuse of this authority by a developer, the Texas Commission on Environmental Quality and the Texas Attorney General must review and approve all park projects built and financed in this manner prior to any repayment to the developer by a water district. Additionally, the law does not allow the transfer of ownership to non-government groups such as an HOA. Maintaining legal rights and ownership to certain park areas is especially critical where the park serves dual purposes – such as providing critical drainage or detention, as well as recreational, purposes.

Recognizing the burden of a “newly” formed district, the Riverstone HOA, under no obligation, agreed to operate and maintain the LID 19 park areas. Meant to be a temporary arrangement, this agreement is renegotiated annually. Prior to the renewal of this agreement, the district evaluates options to ensure we are continuously providing the best service at the best cost to the district.
