Site Data That Supports Accurate Building Plans
Design Support Surveys in the Quad Cities and surrounding areas for architects and engineers requiring topographic and boundary data
Floodplain properties and river valley development sites along the Mississippi River corridor demand certified existing conditions surveys and elevation data before design work can advance through municipal and regulatory approval processes. Abbitt Survey & Development, PLLC conducts topographic and boundary surveys with AutoCAD deliverables for architects and engineers designing site improvements and buildings in the Quad Cities and surrounding areas. Licensed surveyors provide interior and exterior measurements, elevations, and topographic detail that integrate directly into design plan sets for grading, drainage, and building layout decisions.
The survey captures existing site conditions—structures, utilities, surface features, vegetation, and elevation changes—that determine how stormwater moves, where foundations can be placed, and what grading adjustments are required. Topographic data shows slopes, drainage patterns, and features that affect construction feasibility, while boundary surveys confirm property limits and easements that constrain design options. The AutoCAD format allows architects and engineers to overlay design elements directly onto surveyed conditions, avoiding conflicts between proposed improvements and existing site realities.
Schedule a site evaluation to coordinate survey scope with your design timeline and permitting requirements.

What Design Professionals Receive from the Survey
Licensed surveyors measure interior and exterior dimensions, record elevations at key points across the site, and map topographic features using total station and GPS equipment. The resulting AutoCAD file includes boundary lines, easements, building footprints, pavement edges, utility locations, tree canopy limits, contour lines, and spot elevations at intervals that match the design scale and project complexity.
Once the survey is complete, you work from a file that layers directly into your design software, eliminating guesswork about where existing features sit relative to proposed improvements. Design decisions about building placement, driveway grades, stormwater detention sizing, and utility routing are made with accurate elevation data and spatial relationships, reducing the likelihood of costly field changes during construction. Municipal reviewers and permitting agencies require this certified data to evaluate grading plans, floodplain compliance, and stormwater management strategies.
Survey deliverables also include a legal description of the boundary and a certification from the licensed surveyor, supporting title work and zoning reviews. Properties near the Mississippi River or within mapped floodplains require elevation certificates and flood zone documentation, which are prepared using the surveyed site data.
Questions Architects and Engineers Ask
Design professionals working on site improvement and building projects often ask about survey scope, deliverable formats, and timing before coordinating with municipal review processes.
What level of topographic detail is included in the survey?
The survey captures contour intervals and spot elevations appropriate to the project scale, typically one-foot contours for grading design and spot elevations at building corners, utility connections, pavement edges, and drainage features.
How does floodplain location affect the survey scope in East Moline?
Properties within FEMA-mapped floodplains or adjacent to the Mississippi River require elevation certificates and floodway data, which are prepared using surveyed elevations and certified by the licensed surveyor for submittal to regulatory agencies.
Can the survey file integrate with my design software?
AutoCAD deliverables are provided in formats compatible with architectural and engineering software, allowing direct import of boundary lines, topographic features, and existing site elements into your design plan set.
What boundary information is included?
The survey establishes property corners, boundary lines, easements, and right-of-way limits, confirming the area available for design improvements and identifying access constraints or utility corridors that affect site layout.
How soon can fieldwork begin after project authorization?
Licensed surveyors typically schedule fieldwork within one week of authorization, with AutoCAD deliverables completed within ten to fourteen days depending on site size, access conditions, and the level of topographic detail required for your design phase.
Abbitt Survey & Development, PLLC coordinates survey timing and deliverable format with your design schedule and permitting deadlines. Request a project consultation to confirm survey scope and AutoCAD format requirements for your site improvement or building design work.
