A. Surveying Standards and Requirements

Requirements for Topographic Surveys within City right of way

The survey will be performed by a Professional Land Surveyor in the State of Florida pursuant to Chapter 472.027 of Florida Statutes and shall meet the minimum technical standards identified in Chapter 61G17-6, FAC.  All survey files will be prepared in AutoCAD format using City of Miami Beach Standards.

General Requirements:  As a minimum, topographic surveys will address the following:

• Establish a baseline with 100-foot stations, monuments as required by the Chapter 61G17-6, Florida Administrative Code and Chapter 472.027 of Florida Statutes shall be set by the Surveyor along the baseline at all changes in alignment, points of curvature, block corners and at all street intersections .  The baseline of the survey shall be tied to the right-of-way and sectionalized land monuments.  Each surveyor will be responsible for obtaining right-of-way information from available records

• The surveyor will set benchmarks at convenient locations along the corridor to be used during the design and construction phases of the project.  As a minimum, permanent benchmarks shall be set at 1,000-foot intervals along the alignment.  The surveyor shall tie-in at least two existing government county monuments to the vertical circuit and take cross sections at 100-foot intervals along the entire project corridor.  Benchmarks shall be derived from existing government benchmarks and carried into the proposed system using Second Order, Class II procedures.  A full listing of benchmark locations shall accompany the survey data.

• Cross section elevations shall define all grade breaks such as intersections, swale, edge of pavement, pavement centerline, curb and gutter, edges of sidewalk, driveway connections, right-of-way line, edge of the 25-foot right-of-way offset, encroachments (both natural and built-in), etc.

• The surveyor shall locate and identify all visible surface improvements and topographic features that exist along the width of the corridor, such as the following:

• Existing valve boxes, water / electrical meter boxes, electrical pull boxes, telephone / cable risers, fences, hydrants, etc.

• Aboveground and underground utilities, invert elevations of accessible underground utilities, wood / concrete utility poles, culverts, guardrails, pavement limits, headwalls, end-walls, manholes, vaults, mailboxes, driveways, side streets, trees, landscaping, traffic signage and any other noted improvements.  Note that survey will identify fence material / height, landscaping plant material limits and driveway construction materials; as well as private property encroachments (i.e. landscaping, overhangs, improvements, etc.)

• Survey limits shall include the entire right-of-way and an additional overlap of 25-feet on either side of the right-of-way.

• All locations shall be tied to the Florida State Plane Coordinate System, East Zone (NAD 83/90).

• All vertical control shall be City of Miami Beach Datum (Mean Low Water Bay Datum).

• Survey data will indicate geometry of perimeter private property plats (inclusive of fences, landscaping and driveways).

The surveyor shall coordinate with each utility agency in an effort to identify the location of all existing underground utilities in case that this information is needed.
