Tab 4 - Approach / Methodology
<br />Existing Conditions and Basis of Design
<br />CTS will begin by defining the functional and operational requirements of the assignment and
<br />documenting existing roadway, drainage, utility, structural, site, access, and maintenance conditions.
<br />Depending on the project, this may include:
<br />• Survey, SUE, utility-record research, and subsurface investigation;
<br />• Drainage-system inventory and condition assessment;
<br />• Hydrologic and hydraulic analysis;
<br />• Pump station, well, force-main, control, and power-system review;
<br />• Pavement, sidewalk, curb, structural, or facility assessment;
<br />• Water and wastewater system review;
<br />• Right-of-way and property-access evaluation; and
<br />• Review of existing permits, maintenance records, prior studies, and flood complaints.
<br />For drainage and pump-related assignments, CTS will evaluate rainfall, tailwater and groundwater
<br />conditions, system capacity, pump reliability, redundancy, emergency operation, backflow prevention,
<br />maintainability, access, controls, power requirements, and interaction with adjacent drainage
<br />infrastructure. Current and reasonably foreseeable future conditions will be incorporated when
<br />appropriate so improvements support the City’s broader flood-resilience and adaptation objectives.
<br />Alternative Development and Design
<br />CTS will develop solutions that balance technical performance with the realities of working in a densely
<br />developed coastal municipality. Alternatives will consider:
<br />• Flood reduction and system reliability;
<br />• Roadway, pedestrian, bicycle, and ADA needs;
<br />• Utility conflicts and service continuity;
<br />• Right-of-way and easement limitations;
<br />• Access to residential towers, businesses, parks, beaches, and public facilities;
<br />• Construction staging and emergency access;
<br />• Environmental and regulatory requirements;
<br />• Long-term maintenance and life-cycle cost;
<br />• Compatibility with active and planned City projects; and
<br />• Available capital and grant funding.
<br />For work near Collins Avenue, Sunny Isles Boulevard, North Bay Road, Atlantic Boulevard, and other
<br />constrained locations, CTS will identify active City, FDOT, County, utility, and private-development
<br />projects. This will help avoid conflicting designs, repeated construction, utility relocations that interfere
<br />with future work, and unnecessary disruption to residents and businesses.
<br />Once the City selects an alternative, CTS will advance the design through the required milestones.
<br />Roadway, drainage, water, wastewater, structural, electrical, mechanical, geotechnical, survey, utility,
<br />landscape, and traffic elements will be coordinated before each submittal. City comments will be
<br />recorded in a comment-resolution log and tracked through closure.
