RIVER DES PERES CSO TUNNEL

Surveys performed in support of the River Des Peres CSO tunnel design were generally divided into five categories; control, aerial surveys, strip maps, boundary surveys and topographic surveys.

  • A closed field traverse, tied to State Plane Coordinates, was performed and adjusted to Modified State Plane Coordinates in accordance with MSD Standards.  A level loop was performed and tied to an existing MSD benchmark. Both the horizontal and vertical control closed well within acceptable tolerances.  A project Blue Book was prepared showing three point ties for each control point as well as an aerial photograph showing the control point location.

  • Aerial surveys were performed for the CSO tunnel alignment corridor. Approximately 45 target points were surveyed and tied to the project traverse. Aerial mapping and planimetrics were provided for a 560 acre area at a scale of 1”=50’ and a 1’ contour interval.

  • Strip maps were divided into preliminary (50%) and final submittals.  The preliminary strip map was prepared to indicate property lines and ownership to allow the planning of the consolidation sewers and tunnel drop shaft locations to begin before final information was available.  The final strip map was based on a review of available records, surveys and plats from agencies including the City of St Louis, MoDOT and MSD.  A review of all easement searches was performed. The final strip map was prepared meeting MSD standards.

  • A boundary survey was prepared for the River Des Peres right-of-way from Broadway to approximately 1600 feet east of Macklind. Information used to establish the right-of-way included the original City of St Louis ordinance which established the River Des Peres Drainage Works, City dedication plats and assessors maps, deeds from adjoining property owners and District records. The Boundary Survey drawing includes descriptions of the right-of-way parcels. Property corners were monumented in the field in accordance with Missouri Minimum Standards.

  • Topographic surveys were prepared in limited areas to provide data required for preliminary design,and included utility and sewer surveys.  Missouri One Call was contacted to locate utilities in selected areas. Marked utilities and top and flow line of sewers were collected in the field. Surveys in support of the geotechnical program were also performed.  Boring locations and elevations were collected as requested.

JEFFERSON BARRACKS TUNNEL

Surveys performed in support of the preliminary consolidation sewer design were generally divided into three categories; control, strip maps and topographic surveys.


  • A closed field traverse, tied to State Plane Coordinates, was performed and adjusted to Modified State Plane Coordinates in accord with District Standards.  A level loop was performed and tied to an existing MSD benchmark. Both the horizontal and vertical control closed well within acceptable tolerances. A project Blue Book was prepared showing three point ties for each control point as well as an aerial photograph showing the control point location.


  • Strip maps were divided into preliminary (50%) and final submittals. The preliminary strip map was prepared to indicate property lines and ownership to allow the design of the consolidation sewers and tunnel drop shaft locations to begin before final information was available. The final strip map was based on a review of available records, surveys and plats from agencies including St Louis County, MoDOT and the District. Additional records research by the title company was necessary to determine the location of the property line between the Piatchek and Riverfront, LLC properties, in the area south of I-255. A review of all easement searches was performed. The final strip map was prepared meeting District standards.


  • Topographic surveys were prepared in limited areas to provide data required for preliminary design,and included utility and sewer surveys.  Missouri One Call was contacted to locate utilities in selected areas. Marked utilities and top and flow line of sewers was collected in the field. The field team was unable to locate several sewers. The District is assisting with sewer locations in critical areas. Surveys in support of the geotechnical program were also performed. Boring locations and elevations were collected as requested.  A survey of the bluff at the Bussen Quarry site and along the railroad tracks north of I-255 was also performed to identify rock elevations.

CITY OF FESTUS WATER MAIN

Kowelman Engineering, Inc. performed detailed topographic surveys for more than sixteen different reaches of proposed water main improvement projects throughout the City of Festus.  Kowelman Engineering, Inc. employed the use of Global Positioning Satellite (GPS) surveying procedures to establish uniform control throughout the entire program area.  Upon establishment of the horizontal and vertical control for each reach of water main improvements, Kowelman Engineering was able to develop topographic maps that were overlayed onto aerial photographs of the entire area, in one coordinate system.
