Having lived through devastating floods over the last four years, Houstonians have rallied to rebuild and recover. That includes looking for new ways to reduce flood risk.
One of the most promising involves using nature to fight flooding. Those measures include creating more parks and open spaces; making ample room for water in our bayous; conserving natural areas; restoring grasslands and forests; and smaller-scale projects such as permeable parking lots, green roofs and new lawn grasses with longer, water-absorbing roots.
No, nature-based solutions alone will not eliminate flooding. But combined with more traditional engineering projects — levees, constructed detention ponds and drainage-improvement structures — they can do a great deal to manage and diffuse the effects of flooding while also providing major side benefits: scenic and recreational amenities, improved water quality, boosts to tourism and locally grown food from community farms.
Not to mention that nature-based solutions also are highly cost-efficient, often several times more so than traditional flood-control public works. A National Wildlife Federation study indicated that every $1 spent in preventive measures saves $4 in disaster recovery costs. The study also noted that protecting open space and existing natural habitats are among the most cost-effective ways to reduce risks to communities.
