1. Introduction
This document provides requirements for surveying performed for projects associated with
the City of Baton Rouge/Parish of East Baton Rouge (C-P) Sanitary Sewer Overflow (SSO)
Control and Wastewater Facilities Program. The term Engineer is defined as an engineering
design firm under contract with the C-P and producing engineering design work on the
Program. These requirements are provided to encourage consistency in the design approach
used by various Engineers.
While the purpose of these requirements is to assure uniformity, it is not intended to stifle
Engineer’s creativity, design innovation, and ingenuity. Engineers shall review these
requirements and adopt them for design of the facilities for which they are responsible.
Engineers are ultimately responsible for their design, and this responsibility is in no way
diluted or absolved by these requirements.
It may be necessary for the Engineer to deviate from these requirements. In such cases, the
Engineer shall immediately bring this matter to the attention of the Program Manager (PM)
by completing and submitting the form included in the Program Requirements for Engineers.
The PM reserves the right to allow or disallow the deviation from the requirements. If the
deviation will impact design contract terms, then a Supplemental Agreement will be
negotiated between the Engineer, the PM, and the C-P.

2. General
The surveyor shall follow the current standards of practice as outlined in the Laws and
Rules of the Louisiana Professional Engineering and Land Survey Board in conducting
surveys. As such, all work shall adhere to modern surveying theory, practice, and
procedures. Surveys shall be performed in English units and all data collected shall be
reduced to state plane coordinates.
If right-of-way or servitude maps are required for the project, they shall be prepared in
accordance with the Program Right-of-Way Map/Real Estate Standards.
MKE/092380086 3-1 REV. 1 / AUGUST 2009
3. Control Points
Horizontal and vertical control points for design, topographic, boundary, and construction
surveys shall meet the accuracy of surveys for a Class A (Urban) Survey as outlined in the
Rules of the Louisiana Professional Engineering and Land Survey Board. Horizontal control
shall be NAD 83 (92) and vertical control shall be NAVD 88. Surveyor shall only use EBR 88
monuments.
As part of the C-P SSO Program, the C-P Department of Public Works (DPW), in
conjunction with the U. S. Army Corps of Engineers, New Orleans District, has established
20 vertical control benchmarks to be utilized for surveying performed as part of the
Program. Information related to these benchmarks including their locations is available on
the Program Web site at www.brprojects.com/sewer/pages/contractor_guidelines.htm.

4. Survey Limits and Cross Sections
The Engineer shall perform survey work to determine all surface features and at or below
ground elevations at the project site and/or located within the right-of-way along the entire
alignment and other areas as may be necessary to develop plan and profiles and site plans
for the recommended project. The Engineer may choose to utilize Global Positioning System
(GPS) data for mapping of x-y coordinates. The scope of the surveying work shall include,
but not be limited to:
• Determining boundary conditions (site property boundary, temporary and permanent
servitude widths determined, and rights-of-way-widths).
• Confirming existing facilities controls and elevations with current survey and
Establishing additional survey control points where required.
• Identifying mapping options and develop preliminary and/or final design mapping.
• Performing field survey in State Plane Coordinate control. All existing surface features
within the project limits shall be shown. Surface features include, but are not limited to,
edge of pavement, pavement type, curb, gutter, sidewalks, retaining walls, driveways,
parking lots, utility poles, utility towers, overhead electric lines, pavement markings
(including type of pavement marking), traffic lights, traffic signs, all other signs, tree
type and trunk diameter, drainage channels (including invert and water surface
elevations at sewer line crossing), water bodies (ditches, streams, creeks, rivers, ponds,
etc.) including invert and water surface elevations at sewer line crossing, railroads,
structures, bridges, columns, telephone boxes, fences, gates, and all other surface
features. The size and type of all surface features shall be shown.
• Performing phased or final design level mapping.
• Defining legal issues and constraints (ownership’s, zoning, servitudes, etc.).
• Obtaining parcel maps and ownership information within the project limits. Property
corner surveys shall be conducted within the project limits. All existing lot numbers and
plat information shall be shown.
• Field surveying pavement match points (curbs, gutter, sidewalk, pavements, etc.).
• Researching and showing records of existing adjacent public utility systems.
• Plotting all existing utilities (see Louisiana R.S. 38:2223).
• Field surveying and showing on drawings all underground features and utilities within
the project limits. These include, but are not limited to, sanitary and storm sewers,
water, gas, electric, telephone, cable, fiber optic, traffic loops, services (water, sewer, gas,
and all other services), manholes (including top and invert elevation), utility vaults
(including top and invert elevation), valve boxes (water valves, sewer valves, gas valves,
and all other valves, including top and invert elevations), storm inlets (including top and

invert elevation), junction boxes (including top and invert elevation), utility
appurtenances, cleanouts, water meters, lift stations (wet wells, dry wells, and aboveground
piping and valves, including top and invert elevations for wet wells and dry
wells and surface drains and centerline elevations for above-ground piping and valves),
septic systems, storage tanks, and all other underground features. The type, size,
alignment, depth, and top and invert elevations of the underground features shall be
noted. Slopes and flow lines shall be noted for existing sewer lines. Materials of
construction of underground utilities shall be provided where available.
• Survey existing building floor elevations at all identified pump station sites. Provide one
XYZ coordinate on flat open ground in the immediate vicinity of each of the identified
existing and proposed pump stations.
If applicable, special areas or elements to be mapped (using GPS data) include:
• Hazardous materials
• Archaeologically important areas
• Wetlands/endangered species
• Flood plains
• Geotechnical exploration drill holes and test pits

5. Utility Locations
The Engineer shall collect as-built utility drawings and utility inventory from the Program
Manager. The surveyor shall collect all visible utilities and utility markers and show them
on the survey plans. The surveyor shall also call LA One Call and collect location of the
underground utilities as indicated by LA One Call. Surveyor shall submit call or reference
number received from LA One Call to the Program Manager as verification of the request
for utility locations. If additional utility location activities are included in the Project scope,
such as potholing, the surveyor will also include the locations of all utilities located by these
additional activities on the survey plans and profiles, as applicable.

6. Deliverables
The survey shall include the following deliverables, to be submitted with other design
deliverables, as appropriate.
• Copy of all survey notes and field roll
• Plan and profiles broken into 24 x 36-inch sheets with station and offset to all utility
poles, fire hydrants, building corners, headwalls, and drainage structures
• Vertical profiles showing the existing centerline ground surface above the proposed pipe
or structure, drainage pipes, pipeline crossings, utilities, ditch centerlines, and other
critical information
• AutoCAD drawings, in accordance with the Program CAD Requirements, showing all
collected data in three dimensional coordinates along with the required pen setting files
