HomeMy WebLinkAbout2025 12 18 Public input - Documents submitted by Art Gallo7.6. Proposed Maintenance Programs
The City currently performs maintenance on an as needed basis through work orders as
described in Stormwater Related Work Orders. The City also performs maintenance
necessary to remain in compliance with their MS4 permit and FDOT requirements. The City
does not currently perform maintenance on a proactive basis through a comprehensive
plan.

The City desires to create a proactive maintenance program for stormwater assets that the
City owns and operates. These assets include public and private ponds, stormwater pipes,
channels and ditches, and bridges. The establishment of a maintenance program will enable
the City to track the status of its assets and preemptively identify assets in need of
maintenance before they fail, resulting in better stormwater management and reduced
costs. The creation of a proactive maintenance program requires the addition of staff
dedicated to performing prescribed inspection and maintenance activities in addition to
existing City maintenance staff.
MNT-001 — Pond Inspection & Maintenance
Numerous stormwater ponds, both publicly and privately owned, existing within the City and
help manage stormwater runoff and improve water quality. Regular maintenance is required,
including mowing, removing sediment and vegetation, and inspecting or repairing berms to
keep these ponds operating effectively.
To improve the management of these ponds, the City is encouraged to create a formal
inspection and maintenance program. This program should ensure that all ponds are
inspected and maintained regularly by the responsible entity. Inspections are recommended
at least twice per year and after major storm events. A GIS database would be used to track
each pond within City limits, recording details such as ownership, current condition,
relevant permits, and the maintenance schedule.
For public ponds, the City should develop and follow its own maintenance schedule. For
private ponds, as well as hybrid ponds where both public and private interests are involved,
the maintenance policy is still to be determined as of the time of this report. If inspections
show that maintenance standards are not met, corrective actions such as sediment removal
or restoring vegetation may be needed. The City may impose fines on owners who are
noncompliant with maintenance requirements.
MNT-002 — CMP Program
The City of Winter Springs has an estimated 3,405-LF of CMP throughout its limits. CMP has
a relatively limited lifespan compared to alternate materials and require additional O&M
considerations. It is therefore recommended that the City develop a program to identify
intervention requirements for the City's CMP system. Intervention requirements will be
based on pipe age and condition, which can be implemented into a GIS-based database that
the City can manage internally. Intervention methods will include additional condition
assessment, investigation for condition, replacing positions of pipe, slip lining, and
additional monitoring. The program will begin with the City's older CMP pipes and work into
more recently installed CMP in later years.

Existing Level of Services Analysis
The floodplains generated from the Howell Creek Watershed Model depict flooding of
Vistawilla Drive in the 25-year and 100-year storms. This crossing does not meet the 25-year
LOS in existing conditions due to overtopping of the road. This crossing also fails to meet the
100-year LOS in existing conditions due to inundation of several structures.
Proposed Improvement
This project proposes removing the existing 24-inch RCPs and replacing them with three 60-
inch x 38-inch elliptical RCPs. This improvement does not propose any improvements to the
channel upstream or downstream of the Vistawilla Drive crossing. See Figure 32 for a
diagram of the proposed improvements.

Areas of Concern
Jetta Point Park
Jetta Point Park, located in the northeast Howell Creek Watershed, was identified by Ardurra
as impacted by Hurricane Milton in 2024. During the storm, runoff overflowed from
neighboring subdivisions, causing the pond level to rise and local drainage to backflow into
streets and yards. Proposed solutions include berm restoration and an interceptor swale,
designed to discharge through a drop structure upstream of Vistawilla.
