17. Developers will be responsible throughout their development
activities for obtaining compliance with the provisions of Texas Water Code,
Sect. 11.086, and this shall include having appropriate drainage studies and
plans prepared and sealed pursuant to the PROFESSIONAL ENGINEERS DISCIPLINARY
RULES DR 1.1, 2.2 and 3.1 and ETHICAL CONSIDERATIONS EC 6.3 and 6.4. Water
concentrated in streets, pipes, drains, culverts, and channels will be moved
to a recognized watercourse without damage to intervening structures or undue
spreading across intervening land.
A "recognized watercourse" shall herein be defined as either an open
channel with hydaulic characteristics which provide capacity for at least a
la-year frequency storm after ultimate development of it's watershed, or an
underground storm drain with capacity for at least a 5-year frequency storm
plus overlay relief sufficient to safely discharge up to a combined la-year
frequency flow (based on ultimate watershed development) without damage to
adjacent property. Such la-year capacity shall extend downstream from the
point of discharge or the developer s property line which ever is greater,
a distance of at least 100 ft. Typical examples of such "recognized watercourses"
are the main channels of Mackey, Calloway, Walker, Big Fossil, Little Bear,
and Mesquire Branch Creeks, or those tributary creeks, streams, channels or
underground storm drains which meet the hydraulic capacity requirements of a
"recognized watercourse". The developer is responsible for constructing all
offsite channelization or underground storm drain with overland relief, required
to discharge concentrated stormwater from the low end of his development to the
reconginzed watercourse, and also to obtain all necessary easements from
intervening land.·owners. Calculations will be required to show that connecting
off site drainageways are capable of handling any increase in runoff due to
development, concentration, or diversion for at least the la-year storm frequency.
