Proposals for sheet flow pathways, likewise, did not address whether the <br />City had the easement necessary to utilize the proposed sheet flow path; the sheet flow <br />path identification was based only upon apparent need and availability of open land for <br />the pathway. Detention ponds, likewise, assumed that acquisition of land could be <br />accomplished at locations where ponds might be located. <br /> <br />However, when making cost estimates for proposed improvements, account was taken of <br />reasonably likely cost for land acquisition. For channel widening, land acquisition for <br />maintenance berms (20-feet on each side of the channel) was assumed. Sheet flow <br />pathways assumed land acquisition would be required for a path 20 feet wide the full <br />length of the proposed pathway. For ponds, estimates of pond area were provided based <br />upon detention requirement and representative pond depth with 30-foot maintenance <br />berms; these areas defined minimum land acquisition requirements for the ponds. <br /> <br />Buy-out of lands with homes was not specifically identified as alternative for addressing <br />flooding problems. Channel widening was limited to estimated existing channel widths, <br />sheet flow paths were selected to avoid existing residents, and detention sites were <br />limited to currently undeveloped lands. Thus buy-out of homes is not being proposed as <br />part of this CWDS though some solutions will require that some portion of selected <br />nearby properties be acquired. <br /> <br />It is recognized that home buy-out is sometimes proposed as a flood control remedy; such <br />buy-out may become necessary in the future, but the current plan is intended not to rely <br />upon this strategy. <br /> <br />5.2.11 Ownership and Maintenance of Drainage Facilities <br /> <br />Within the three watersheds (Clear Creek, Armand, and San Jacinto/Galveston) which <br />compose the City, there are numerous named bayous and ditches.
