(25) acres or less shall be designed using the Rational Method of
calculating runoff in accordance with the City's Stormwater Design
Manual.
2.
Developments where the area contributing runoff is four hundred
(400) acres or less shall be designed using the Rational Method of
calculating runoff or other methods approved by the City Engineer,
or other parties as assigned.

Missouri Guide to Green infrastructure.
3.
Streets, blocks, depth of lots, parks, and other public grounds
shall be located and laid out in such a manner as to minimize the
velocity of overland flow and allow maximum opportunity for infiltration
of stormwater into the ground. By reasonably mimicking pre-construction
runoff conditions, this should be accomplished through methods that

Design discharges to existing and proposed streams and channels
to minimize increases in velocity and peak flows.
5.
Whenever possible, place detention basins, streams and floodplains
within parks and other public grounds.
D.
Enclosed Systems And Open Channels. Unless otherwise permitted by
the City Engineer, or other parties as assigned, the design shall
conform to the criteria in the City of Troy, Storm Sewer Design Standards,
which by reference made a part hereof as though expressly written
and incorporated in this Chapter.
1.
Design the secondary storm drainage system, in single-family
and duplex residential areas, to accommodate the peak flow from a
10-year, 24-hour storm.
2.

(greater than two (2) attached units), commercial, and industrial
areas, to accommodate the peak flow from a 10-year, 24-hour storm.
3.

flood plains, to accommodate the 100-year flood.
4.

detention, provided the developer's professional engineer provides
a hydraulic study showing detention will increase the overall peak
flow in a receiving stream more than development without detention.

A.
Disclaimer Of Liability.
1.
The performance standards and design criteria, set forth herein,
establish minimum requirements which must be implemented with good
engineering practice and workmanship.
2.
Use of the requirements contained herein shall not constitute
a representation, guarantee or warranty of any kind by the City, or
its officers and employees, of the adequacy or safety of any stormwater
management structure or use of land.
3.
The approval of a stormwater management plan and the issuance
of a drainage permit shall not imply that permitted land uses will
be free from damages caused by stormwater runoff.
4.
The degree of protection required by these regulations is considered
reasonable for regulatory purposes and is based on historical records,
engineering, and scientific methods of study. Larger storms may occur
or stormwater runoff heights may be increased by manmade or natural
causes.
5.
These regulations therefore shall not create liability on the
part of the City or any officer with respect to any legislative or
administrative decision lawfully made hereunder.
