Hydrographic Survey. The Parties shall complete a detailed hydrographic 7 survey of all historic and existing water uses on the Reservation within four years of the 8 Enforceability Date. The costs of preparing a hydrographic survey in the amount of 9 $1,000,000 shall be part of the federal obligation in this Agreement. The Navajo Nation 10 shall be responsible to lead the survey effort and perform or contract for such survey. The 11 approach, and method to be used, shall be reviewed with and approved by the State and 12 the United States. The survey shall document all available water measurements and the 13 Parties shall develop Depletion estimates where actual measurements are not available.
Hydrographic Survey. (a) Carrying out of a hydrographic survey within the designated traffic separation scheme in the Strait of Malacca within the Project Area.
(b) Provision of training to the hydrographic surveyors of the hydro-oceanographic services of the Republic of Indonesia, Malaysia and the Republic of Singapore.
Hydrographic Survey. This task includes performing a condition survey as part of the Project Study Report submittal in order to account for any shoaling that may have occurred since the 2005 survey and to update the quantities that Xxxxxxx & Xxxxxx Associates (GBA) calculated in 2005 GBA will utilize the same control, confirm that the elevations are still valid, and apply a weighted average adjustments to the tidal water surface elevations based on a previous tidal study. GBA will monitor tidal elevations at the upstream and downstream locations simultaneously to within a maximum 0.1’ change in tide or every 4 minutes (whichever is more stringent) either manually or with use of an automatic tide gauge. The horizontal positioning system will be NAVSTAR GPS with U.S. Coast Guard Differential Beacon. Plane, grid, bearings and coordinates will be based on the State of California Coordinates System (Xxxxxxx Conformal Projection), Zone III, NAD 83 as described in Special Publication No. 253, published by the National Ocean Survey. For the condition survey sounding lines will be run perpendicular to the channel centerline will be obtained at not greater than 200’ increments and at all channel angle points with soundings not greater than 5 feet apart along the survey line (most soundings will be obtained at an interval of 1.5’ to 2’). Approximately 85 cross-sectional survey lines are planned for the condition survey. All cross-sectional survey lines will be run a minimum distance of 50 feet beyond the toe of the channel where accessible. Additionally, survey lines will be run parallel to and along the dredging prism toes and centerline. • Condition Survey (as a section in the PSR)
Hydrographic Survey. Consultant shall conduct a hydrographic survey of Xxxxxx Creek in the project vicinity. The survey will include the researching of available survey monuments, establishment of local survey control, and collection of topographic and bathymetric survey data for use in updating the effective FEMA hydraulic model. The survey would begin at cross section “A” on the effective FIRM (approximately 2,000 feet upstream of Old Portland Road) to a suitable location downstream of the proposed project. WEST will coordinate with the City of St. Helens regarding access to private properties, as necessary, located upstream of the project site.
Hydrographic Survey. A. Final products of a survey shall be field notes, raw data files, edited ("cleaned") data files, electronic drawing files in AutoCAD™ format (version 2002 or earlier), and 11" x 17" or other sizes paper drawings plotted from CAD files. Such drawings shall show depths and 1 foot contours in relationship to the base map furnished by the Port, at a scale of 1 inch = 100 feet (100 scale), unless otherwise directed by the Port Engineer. Numbers representing depths shall be written at a scale to display no less than 0.9" high in a 100 scale plot, and shall spaced as closely as possible without overwriting.
B. Survey lines shall be run perpendicular to the face of the pier, the berth of which is to be dredged, or to the channel (where applicable) at twenty-five foot (25') maximum intervals, including one line 25 feet landward of the dredge limit, where possible. Such survey lines shall terminate not more than ten feet (10') away from the pier face, nor extend less than fifty feet (50') outside the dredge limit, except where prevented by adjacent piers, in which case, they shall terminate not more than ten feet (10') from such adjacent pier. Surveyed lines shall not vary from planned survey line by more than twelve feet (12') either side of planned line. Additionally, one survey line shall be run parallel to the face of the pier, the berth of which is to be dredged, as close to said pier as safely feasible, but not more than six feet (6') away from the face, and extending the full length of the portion of the pier adjacent to the dredge limit.
C. Field notes shall indicate the location of each sounding line, the date and the time (hour and minutes) each sounding line was taken, and explanation for any line terminated early. Notes shall also include tidal data, i.e., height of tide (Port of San Francisco Datum), bar checks, time of the tide readings and date and location of the tide gauge. Field notes may be made on electronic media.
