Levee Raising Construction Project
First Colony LID#2, (FCLID#2) expects to begin raising the levee surrounding Commonwealth in early December. We will be adding select fill to the western and southern legs of our Levee. The amount of raising will vary from 6” to 24”. The different fill amounts are based on the current differences in elevation along the 2 mile stretch of levee. The western leg will require the most fill dirt. The very eastern portion of our Levee, the portion that parallels Commonwealth Blvd. from St. Michaels to Palm Royale, is already high enough and will not need to be raised. We expect to install about 40,000 cubic yards of fill on our Levee. This will bring our flood protection to at least the 500-year flood level. Currently we are protected to the 100-year flood elevation. We have plenty of room to add the additional height and don’t expect to have to remove any existing trees on our Levee easement. If any trees should need to come down, we are planning to plant new trees in other areas of our community to make up for any trees removed. The construction access points for the earthmovers and dump trucks to raise the levee are shown on the attached map.
On the northern side of our community, Fort Bend County LID#2 (FBCLID#2) will also be raising their southern levee and will be installing about 69,000 cubic yards of select fill. There will be some selective tree removal on their levee, as they don’t have as much room and the natural growth of trees over time has encroached on their levee. The construction access points for FBCLID#2 are also shown on the attached map.
You will be seeing the top layer of grass removed and stockpiled next to the levee. Dump trucks will then bring in select fill and the fill will be placed in lifts or layers and compacted. This compaction is necessary, and you will feel and hear the compactors rolling across the top of the levee. After the layers are complete and inspected by surveyors and geoscience techs, the stockpiled topsoil will be reinstalled. Once all traffic has ceased and the work is completed, we will re-seed the levee to speed up the return of grass growth. Since we typically re-seed and fertilize every spring, we will have that additional bump to get us into the growing season. We will have a good stand of grass this summer and the deep root system should return by next summer.
