(2) The owner shall file with the registry of deeds such legal
instruments as are necessary to allow the City or its designee
to inspect or maintain the stormwater management systems
for compliance with the O&M plan.

K. Litter, debris, yard waste, and all other nonstormwater
discharges except for those listed in Subsection J above are
prohibited. [Added 6-26-2018 by Ord. No. O-18-015]
§ 190-216. Easements.
Where a subdivision is traversed by or requires the construction of a
watercourse or a drainage way, an easement of adequate width shall
be provided for such purpose.

to the MS4. If these discharges are identified as significant
contributors to the MS4, they must be addressed in the illicit
discharge detection and elimination minimum contro] measure
described. [Added 6-26-2018 by Ord. No. O-18-015]
(1) Water line flushing;
(2) Landscape irrigation;
(3) Diverted stream flows;
(4) Rising groundwaters;
(5) Uncontaminated groundwater infiltration [as defined at 40
CFR 35.2005(20)];
(6) Uncontaminated pumped groundwater;

All temporary erosion and sediment control measures shall be
removed after final site stabilization. Trapped sediment and
other disturbed soil areas resulting from the removal of
temporary measures shall be permanently stabilized within
30 days.

[2] Drainage locations which serve 10 or more disturbed
acres at one time and where temporary sediment
basins or equivalent controls are not attainable,
smaller sediment basins and/or sediment traps should
be used. At a minimum, silt fence, vegetative buffer
strips, or equivalent sediment controls are required
for all downslope boundaries (and for those side slope
boundaries deemed appropriate as dictated by
individual site conditions).

G. Redevelopment. Redevelopment of previously developed sites
must meet the stormwater management standards to the
maximum extent possible to be determined by the Planning
Board. The goal is to reduce impervious area by a minimum of
20% or meet the open space requirement in that zoning district.
The application shall include a certification by a registered
professional engineer as to compliance with this standard.

described in Subsection E(1) above, within areas with high
potential pollutant loads:
(a) Source reduction; and
(b) Pretreatment.
The following are prohibited within areas with high potential
pollutant loads located in a Conservation Zone:
