STORM WATER MANAGEMENT PLAN ADDENDUM i
Urban development activities increase impervious surfaces, alter the hydrologic
response of local watersheds, and without mitigation may increase stormwater runoff
rates, volumes and pollutant loads. stormwater discharged from Springfield urban
racilities will be governed oy and meet the requirements of all applicable federal, state,
county and local regulations current at the time of development. ,
Landowners are entitled to have the normal course of natural. drainage maintained on
their properties. Downstream landowners must accept water that naturally comes to
their land from upstream, but they are entitled to not have the changes in the drainage
unreasonably impact their property.
The City will, through its development and permitting processes, strive to assure that
the normal course of drainage is maintained, and to the maximum extent practicable,
.manage changes in stormwater characteristics by mimicking the flows and volumes to
match the predevelopment hydrologic regime. Additionally, the City will require
stormwater treatment best Management Practices be employed upon development,
consistent with applicable codes and standards, such that pollutant loads resulting. from
the development do not have a detriments! impact on receiving waters. If attainment
of these objectives is not practicable, the City will involve affected property owners to
develop measures to address their concerns. Mitigation may be required. A ~ analysis
of drainage impacts of the development upon affected downstream owners, including
the contribution of the development to the cumulative impact based upon current
planning assumptions, will be conducted and appropriate mitigation, if needed, wilt be
determined by the City Engineer..
When the drainage design for a development requires downstream mitigation,
performance standards will be determined at the time of development design, and
either drainage easements shall be obtained from the affected property owners or other
means shall be provided to maintain the function and character of the drainage way.
