Allen TX Drainage & Utility Plans

@christopherm0620

Hi, Primary risk is mismatch between the supplied topo/site layout and City of Allen drafting conventions that cause permit portal rejects; I will eliminate that by validating coordinate systems, title block layers, and City of Allen sheet standards before detailing plan content. I have produced permit-ready Civil 3D DWG plan sheets, plan & profile layouts, and HydroCAD/SWMM detention reports for commercial sites in the Dallas-Fort Worth region, delivering files formatted to municipal title blocks and checklist items for direct portal upload. My background includes setting finished floor elevations, balancing cut-fill with grading contours, sizing storm detention using hydrology/hydraulic modeling, and preparing editable calculation worksheets and an opinion of probable construction cost in spreadsheet form. I will begin by importing your topographic survey and architectural footprints into Civil 3D, confirm coordinate and sheet standards to City of Allen conventions, then produce the Grading / Drainage Plan, Utility Plan with plan & profile sheets, and Stormwater / Detention Plan with HydroCAD or equivalent model and outlet details sized to Allen storm criteria. Deliverables will include PDF and Civil 3D DWG files per sheet, the calculation report with editable worksheets, and the cost spreadsheet formatted for your permit upload. - Do you have the City of Allen checklist you want me to use or should I use the current published checklist from the city portal? - Are there any existing easements, HOA requirements, or off-site analyses included in the project data set? Feel free to reach out if you want to talk through next steps. Christopher
