Floodplain

I. Summary A. Why we exist 1. The Harris County Permit Office began issuing development permits in 1973. 2. Permits are issued in accordance with Harris County regulations to ensure that unincorporated areas of Harris County are able to qualify for flood insurance through the National Flood Insurance Program. 3. The residential department is diligently working to minimize the loss of life and property from high water events (i.e. Floods, Tropical Systems, and etc.) 4. The importance of flood plain management i. During the 20th Century, floods were the number one natural disaster to cause the loss of lives and property, according to the USGS ii. Floodplain management reduces the risk of losing life or property to high water. B. Mission Statement…

Due to the flooding in Lower Onion Creek, Eric Rangel, 17, had to drop out of school due to the financial burden that flooding has imposed on his family. The Lower Onion Creek area flooded twice, once on October 31, 2013, and October 30, 2015. Many Lower Onion Creek residents are living in condemned homes five months after the latest flood. Eric Rangel said after the floods, the city condemned his home. His home was no longer inhabitable, and his family had to seek other shelter options.…

similar ecosystems. Wherein, they may have similar elevations, soil types, sun/shade exposure, and slope aspects. B). The two communities that are the most dissimilar are Saylorville and Prospect Park Floodplain. There is 1.3% similarity between Saylorville and Prospect Park Floodplain (Table 4). This suggest that Saylorville and Prospect Park Floodplain have dissimilar ecosystems. Wherein, the proximity to a body of water that frequently floods, soil-water drainage, soil type, landscape…

Congaree National Park The Forest is the largest hardwood forest in Southeast United States. It is home to thousands of state champion trees and the Wateree and Congaree rivers. The Congaree National Park in Hopkins South is widely known for its history and park culture widely because of its floodplain. Hunter’s since the prehistoric ages, hunters used in to fish. This park is named after the Congaree tribe that inhabited the park, until Spanish explorer Hernando De Soto and the Spaniard…

Voluntary home buyouts are used by the Harris County Flood Control District to reduce flood damages in areas hopelessly deep in the floodplain where structural flood damage reduction projects, like channel modifications or detention basins, are not cost effective and/or beneficial. Generally, these are homes that should have never been built. More than 60 percent of the county was developed before floodplain regulations were implemented in the 1980s. The Flood Control District’s Voluntary Home…

In the world richest biotope, wetlands, and specially floodplains, remain particularly active zones in terms of nutrients, biodiversity, flows spreading, sediment transfer and human activities. Today, these sensitive zones are facing increasing human pressures and augmentation in frequency and intensity of extreme hydrological events. The impact of such extreme events on floodplain ecology and biogeochemistry is still difficult to assess. In this context, hydrodynamic models are attractive tools…

flood maps will add approximately 36,000 buildings to New York City’s 1% annual chance floodplain, a 101% increase over the previous maps. In addition, Congressional changes to the National Flood Insurance Program, enacted in 2012 and 2014, now require owners to pay higher flood insurance premiums for buildings that predate the flood maps, putting financial stress on many homeowners who cannot easily retrofit their buildings to meet NFIP standards. Changes to City codes, most notably Appendix G…

The purpose of this lab was to test for which soil type would be best for food production. The tests included Forest Soil, Floodplain Soil, and Garden Soil. We predicted that garden soil will have the best properties for food production because we expected it to have the highest value of nutrients for plants to grow in and a soil composition that is fit for food production (ex. Water Holding, etc). To test our hypothesis, we ran tests measuring Percent Water Content, Organic Material, Nitrates,…

0D, 1D, 1D+, 2D-, 2D, 2D+, and 3D (Pechlivanidis, Jackson, Mcintyre, & Wheater, 2011). The 0D model involves no physical laws or processes, the flood surface is simply the difference between the terrain and the modeled water surface, where the water surface may be flat or an inclined plane. 1D models, as found in HEC-RAS (U.S. Army Corps of Engineers, http://www.hec.usace.army.mil/software/hec-ras/) and Mike 11 (DHI, http://www.mikebydhi.com/products/mike-11), are based on 1D solutions of Saint…
