Long Term Flood Recovery

Planning Study Background

The City of Jersey Village is located in the upper portion of the White Oak Bayou watershed, and the bayou flows from the headwaters near U.S. Highway 290 west of Huffmeister Road southeast to its confluence with Buffalo Bayou in downtown Houston.

Major flooding occurred along White Oak Bayou in the City of Jersey Village in 1998, 2001, 2002, and 2016.

In the last 20 years, the Flood Control District has implemented more than $95 million worth of improvements to address channel flooding in the White Oak Bayou watershed, including completion of the Jersey Village diversion channel in 2010, as well as completion of multiple stormwater detention basins upstream of Jersey Village. In the last decade, the City completed over $25 million of street and drainage reconstruction efforts, with the primary goal of reducing localized neighborhood flooding.

Despite these significant efforts on behalf of the City and the Flood Control District, more than 230 structures within Jersey Village experienced flooding during the most recent “Tax Day” flooding event on April 18, 2016. The City responded to this severe flooding event by initiating the Jersey Village Long-term Flood Recovery Planning Study. For a cost benefit analysis on the cost of this study, click here.

About the Flood Recovery Planning Study

The Jersey Village Long-term Flood Recovery Plan is an accelerated flood damage reduction study led by Dannenbaum Engineering Corporation with Crouch Environmental Services, Inc. and Kuo and Associates to address repetitive flooding in the City and the surrounding area. In September 2016, the City contracted Dannenbaum Engineering Corporation to rapidly deliver the Jersey Village Long-term Flood Recovery Plan by Summer 2017.

The goal of the Jersey Village Long-term Flood Recovery Planning Study is to develop a flood damage reduction plan that balances social acceptability with economic, hydraulic, and environmental feasibility. The plan will identify both short-term and long-term flood damage reduction projects that can be designed and implemented as funding allows.

Long Term Flood Recovery Projects

The Long Term Flood Recovery Plan recommended four main projects:


There are other additional projects the City is undertaking to further flood mitigation:


Golf Course Berm and 

Drainage and street improvements in the Wall Street Neighborhood

In the study the results from the HEC-HMS models showed that every storm frequency except for the 500-year event was contained within the Golf Course by the berm. Based upon the modeling in the study the total reduction in damages for the 100-year storm was $757,580 for a single event. Additionally, constructing a berm around the Golf Course for detention purposes prevented sheet flow from reaching Wall Street and the surrounding neighborhood, thereby reducing localized flooding.
In February 2018 the City had a survey of the Golf Course completed. That survey information, along with the impact areas based upon possible berm elevation, can be viewed here


As part of the study, the capacity of the storm sewer system in the Wall Street neighborhood was determined by analyzing the smaller storms and comparing the hydraulic grade line (HGL) to the gutter elevations of the streets. After the existing system capacity was determined, the study team developed proposed models that increased the number of inlets and the storm sewer pipe sizes and reduced the HGL to acceptable levels for the smaller storms. The study team performed a mitigation analysis that utilized the proposed storage in the Jersey Meadow Golf Course to ensure no adverse impacts to E127-00-00. The street study also included a phasing plan for construction of the improved storm sewer system. The full analysis and report for the Wall Street System Drainage Improvements is in Appendix 7J.

The berm project and Wall Street Neighborhood project have been rolled into one project for the grant process. It was rolled together as the benefits of the project are closely tied together.


Project Information
The City has had survey work done on the golf course, to ensure the proper design of the berm. 
The City applied for a grant to help with this project. The grant is through TDEM Hurricane Harvey DR-4332 Hazard Mitigation Grant Program.


On July 16, 2018 the City Council voted on the proposed berm design. You can view the proposed design here. You can read the full memo to the Council starting on page 165 of the Council Packet. As such the berm has been designed with these perimeters. 

On September 14, 2018 the City was notified Phase I FEMA grant funding has been approved. FEMA funding is approximately $523,000. It is estimated Phase I (design work and bidding) will take approximately 6 months to complete. After design work is completed FEMA will review the designs and may award funding to do the construction.  

On June 3, 2019 the City received the final design of the Berm Project. The design was forwarded to TDEM and FEMA for their review. It is currently under review. 

CDBG-DR Funding

The City applied for $1,792,344 in funding as part of the Community Development Block Grant - Disaster Recovery (CDBG-DR) program to assist in the construction of the berm and Wall Street neighborhood drainage improvements. On July 19, 2019 the city received the contract for those funds. The environmental work that is required as part of the CDBG-DR program will begin immediately. 



Home Elevation and/or buyout grants

The Plan identified approximately 60 homes that could be candidates for home elevations/buyouts. 
FEMA offers financial assistance to local sponsors for property acquisition and structure demolition (also called a buyout) to create open space in frequently flooded areas. The purpose of the program is to alleviate flood-prone property owners from frequent flooding by purchasing the property and either demolishing or relocating the structure. Although relocating the structure to another site is an option, simply acquiring the land and demolishing the existing structure requires minimal environmental review and is considerably less expensive. Additionally, for a structure to be eligible for a buyout, the property cannot be part of any future planned development project and the owner must be selling the property voluntarily. Any incompatible easements must be extinguished before acquisition.

If FEMA funds are used for demolition or relocation projects, the law requires the property to be maintained as open space by the local sponsor submitting the application. Once the structure is demolished or relocated, the property must be dedicated to uses compatible with open space, recreation or wetlands management practices. No new structures may be built on the property with the exception of a few: public buildings open on all sides, public restrooms or structures compatible with open space, recreation or wetlands management use and applicable floodplain management policies and practices. All of these structures must be elevated or flood proofed to the Base Flood Elevation (BFE) plus one foot of freeboard.

Structure elevation is another FEMA program provided through the HMA program. The purpose of the structure elevation program is to raise an existing structure to an elevation that is equivalent or higher than the Base Flood Elevation (BFE). All structures being elevated must be structurally sound and able to be elevated safely. FEMA requires that structure elevation projects be designed in accordance with NFIP standards in 44 CFR Part 60 and with ASCE 24-14. Distribution of funds for approved projects falls under the same cost share process as the buyout program.

The home elevation program application must include the scope of work, the schedule of the project, and a cost estimate for construction. The scope of work requires specific data such as the physical address and property owner’s name, the name and location of the flooding source, the existing and proposed finished floor elevation, the BFE, the existing foundation type, the proposed elevation method, and a statement that the project will be designed according to NFIP standards in 44 CFR Part 60. FEMA has completed a Sample Engineering Case Study for Elevation to demonstrate all the information typically required in a structure elevation application.

Federal FY17 Project Information
On September 11, 2017 the City Council held a special meeting to discuss elevations and buyouts. You can find the presentation from that meeting here. 

The City Council authorized an application to seek funding to elevate 18 homes in Jersey Village. As this is a very competitive grant program funded by FEMA the City must phase the applications. This will be a multiyear projects where the city will seek funding for home elevations year after year.
The City submitted their application in September 2017. As of March 26, 2018 the elevation projects for the City of Jersey Village have been “Identified for further review” by FEMA.


As of September 2019 the City has requested the funds from the state to begin the 9 elevations. It could take 3 months for the money to reach the city. Once the money reaches the city the elevations will commence. Once the first 9 elevations are at 75% completion the city can request the funds for the last 9 home elevations.  


Federal FY18 Project Information

On October 8, 2018 the City Council held a work session to discuss the FY18 application for home elevations. You can view that presentation here.  Video from that work session can be found here. The work on the E100 project has changed the outlook for this and future years. 

This year staff recommended elevations for 4 homes on Jersey Drive, and mitigation reconstruction grants for homes on Jersey Drive between Lakeview and the pool. Staff also recommended applying for a grant to design the deepening and widening of the E127 through Jersey Village, which was included in the HCFCD Bond Program. Council authorized these grants and the grants were submitted in November 2018. It is anticipated there will be an award date of spring 2019. 

The home elevations for 4 homes was approved by FEMA. The application is still under further review. The mitigation reconstruction grants were not funded. The City was identified for further review for the design work of the E127. It is anticipated final approval of these grants will be given in Spring 2020. 

Federal FY19 Project Information

On November 18, 2019 the City Council will hear a recommendation from staff to apply for grant funding to elevate 31 homes. The application is due to the state in late November 2019. Grant approvals are anticipated in May 2020, but final grant awards will likely not happen until Spring 2021. 

The City will be applying for funding from FEMA for more elevations and/or buyouts as funding becomes available. 

Widening and deepening the bayou


The White Oak Bayou is controlled by the Harris County Flood Control District (HCFCD). The city is in communication with them about deepening and widening the bayou. This is a project that is currently on their list. However, they must complete work downstream of us before they can do the work on the portion of the bayou that runs through Jersey Village.

The Bipartisan Budget Act of 2018 (Act) passed February 9th did contain substantial appropriation amounts and provisions that favor Texas, Harris County, and the U.S. Army Corps of Engineers/HCFCD partnered White Oak Bayou flood risk reduction project. The City and Harris County Flood Control District are very grateful for what our Texas delegation accomplished.

Here is a breakdown of the $17.39 billion in funding approved for the U.S. Army Corps of Engineers:

  • $15.055 billion for repairs to ongoing construction projects, and to expedite construction projects that will help mitigate future disaster damage
    • The completion of ongoing projects, such as Project Brays, would be at full Federal expense.
    • $10.425 billion of the construction funding will be used to expedite construction of projects for flood and storm damage reduction in areas affected by Hurricanes Harvey, Irma, or Maria. All authorized projects in Harris County, such as White Oak Bayou, are eligible for this funding.
    • $4.63 billion of the construction funding will be used for projects in states that have had more than one flood-related major disaster since 2014. Harris County would also be eligible for this funding.
    • Construction funds could be used for projects that are studied as a result of the investigations the bill allows for. This will allow us to undertake studies for potential new projects such the 3rd reservoir, and have the funding available to begin construction.


On Monday, March 26, 2018 City officials attended the County Commissioners Court meeting to advocate for allowing HCFCD to begin negotiations to deepen and widen the White Oak Bayou E-100 from Tidwell to FM1960, which includes through Jersey Village. We are excited the Commissioners approved this. HCFCD will begin negotiations and will have a contract brought to the Commissioners at a later date. Design work should be completed in March 2020, and the construction work will take another year. HCFCD believes construction will begin in Summer 2020. 

According to HCFCD the plan is to widen the E-100 channel to 30 feet (at the base of the bayou) through Jersey Village, and the E-200 (the bypass) Channel to 20 feet. The City has been in contact with HCFCD about whether or not more land is required to widen the bayou. HCFCD has stated at this time no home buyouts within Jersey Village are needed to widen E-100. The design of the project is still on going. 

On July 6, 2018 it was announced that the Army Corps of Engineers has allocated about $45 million to the deepening and widening project. 

The City is working closely with HCFCD to ensure this project is completed. You can view project information on the HCFCD website.


Widening and deepening the bayou


As part of the Harris County Flood Control District (HCFCD) Bond Program the City of Jersey Village worked closely with HCFCD to have a deepening and widening of the E127 channel through Jersey Village be a part of the program. This project was included in the Bond Program.  

In November 2018 the City applied to FEMA for a grant to do the design piece of this project. In May of 2019 the city was "identified for further review" for this grant. This review process could take up to 1 year. After that the city will work with HCFCD to begin the design process. 

Tear Down and Rebuild

The City is working to find home builders or developers that maybe interested in partnering with the city to buy homes that are in the flood plain and rebuild homes that would be above the flood plain. This project would not have federal funds attached to it, and would be an incentive from the city to a home builder. 


Community Rating System (CRS)

As part of the commitment to flood mitigation the City of Jersey Village has been working to join the National Flood Insurance Program’s (NFIP) Community Rating System (CRS). CRS is a voluntary incentive program that recognizes and encourages community floodplain management activities that exceed the minimum NFIP requirements.

As a result, flood insurance premium rates are discounted to reflect the reduced flood risk resulting from the community actions meeting the three goals of the CRS:
Reduce flood damage to insurable property;
Strengthen and support the insurance aspects of the NFIP, and
Encourage a comprehensive approach to floodplain management.

Based upon the draft verification report, the City is anticipating to be a Class 7 Community. The verification report is subject to acceptance by FEMA. When that occurs the City’s participation in CRS will be effective May 1, 2020. 

Being a Class 7 Community means people living in the Special Flood Hazard Area (SFHA) (the 100 year or 500 year flood plain) will see a 15% discount on their flood insurance premiums. Anyone living outside of the SFHA would receive a 5% discount on their flood insurance premiums. These discounts would be reflected on policies after May 1, 2020. 

Being a part of CRS also provides more points in the scoring criteria for grants, such as home elevation grants, the city applies for from FEMA.

Long Term Flood Recovery Plan Cost Benefit Analysis

The Long Term Flood Recovery Plan evaluated several possible projects. Each one of the projects was measured by how it reduced flooding and the benefit-cost ratio of the project. A benefit-cost ratio (BCR) is an indicator, used in cost-benefit analysis, that attempts to summarize the overall value for money of a project. A BCR is the ratio of the benefits of a project, expressed in monetary terms, relative to its costs, also expressed in monetary terms.


If the cost of a project outweighs the benefits of a project, the project has a BCR of less than 1. If the benefits of a project are higher then the cost of the project, the project has a BCR of greater than 1. A score of 1 means the project simply breaks even.


Using the Long Term Flood Recovery Plan the city has been able to apply for seven different grants, as of June 2019. One grant was not funded. The City has been successful in five of those grants so far, and another one has been submitted.  The city has been awarded $6,553,093 in grant funds. The cost of the Long Term Flood Recovery Plan was $620,917. Applying the same benefit-cost ratio to the Long Term Flood Recovery Plan shows a BCR of 10.55. This shows the benefits that were received from conducting the Long Term Flood Recovery Plan outweigh the costs by a factor of more than 10. 

 Graph showing Cost-Benefit of Long Term Flood Recovery Plan

Having the Long Term Flood Recovery Plan completed gave us the data that is required to make successful grant applications. The timing of the completion of the study put us in a much better position to make early and compelling applications which is what led to the awarding of these grant funds. Without having the data from the Long Term Flood Recovery Plan the grant applications would not have been as complete or as comprehensive, which means we most likely would not have received funding without the data.

Below is a listing of the grants that have been applied for and the grant amount requested for each project.
Grant Amounts Awarded
FY17 Home Elevation Grant  $        3,355,448
Wall Street and Berm Grant (Phase I) - HMGP  $            523,298
E127 Deeping and Widening Plan  $            100,000
Home Elevation 2019 Grants  $            782,003
Wall Street and Berm Grant - CDBG-DR  $        1,792,344
Total Awarded  $        6,553,093
Benefit Cost Ratio (Grant Amounts Awarded Divided by Cost) 10.55
Grants Submitted (Not Yet Awarded)
Wall Street and Berm Grant (Phase II) - HMGP  $        3,704,150
Home Elevation 2020 Grants $         9,223,850
Total Grants Submitted And Not Yet Awarded  $       12,928,000
Cost of Long Term Flood Recovery Plan  $            620,917


Utilizing the data from the Long Term Flood Recovery Plan the city will continue to apply for grants as they come available. Implementation of the Long Term Flood Recovery Plan is a high priority for the city.
