Allen TX Drainage & Utility Plans

@jacob745

Hello, I am a licensed Civil PE with over 20 years of experience in grading, drainage, utility, detention, and municipal site-development design. I can prepare the three permit-ready sheets required for your City of Allen project and coordinate them with the supplied survey, site plan, and architectural footprints. My scope will include: • Finished floor elevations, spot grades, and contours • Cut/fill-conscious grading and positive drainage • Water, sanitary sewer, and storm utility layouts • Plan/profile information and city-standard appurtenances • Detention sizing and outlet structure design • Hydrologic/hydraulic calculations • Civil 3D DWG and permit-ready PDF files • Editable calculation worksheets • Opinion of probable construction cost I work primarily in Civil 3D and can use HydroCAD/SWMM or equivalent tools for detention modeling. I will format the package around City of Allen submission requirements and coordinate normal review comments. Please send the survey, site layout, and architectural footprint files.

Hi, Your Allen, Texas project is a strong match for my civil site-design background. I can take the project from base survey through coordinated grading, utility, and stormwater/detention plans suitable for permit submission. Deliverables will include: • Grading/Drainage Plan • Utility Plan • Stormwater/Detention Plan • Water, sanitary, and storm profiles • Detention and outlet calculations • Construction details and notes • Civil 3D source files and PDFs • Editable hydrology worksheets • Construction cost estimate I have extensive experience with commercial and residential site development, drainage modeling, storm sewer sizing, utility coordination, and municipal plan review. My goal will be to minimize conflicts, provide practical grading, and develop a detention solution that satisfies release-rate and storage requirements without unnecessary construction cost. I can provide a firm schedule after reviewing the project data set and site acreage.

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
