Engineering Services We Provide

The first step toward successful land development is due diligence.

We Have What It Takes

At AEG, we have the knowledge and experience to see your project through to success.

 With the ability to approach each unique project with foresight, we are committed to providing our clients excellent civil engineering services in the greater Denton area and beyond.

Our Approach and Coordination


First, Seek To Understand

your vision, goals & objectives

Visit The Site

and design the project by visualizing how it will fit on the site.

Prepare A Design Drawing

and present it to you to verify that we have captured your vision.


Process The Application

through the appropriate agencies

Continued communication with you is a priority in our coordination efforts.

Due Diligence

  1. Research ordinances, regulations, and federal requirements applicable to your project.
  2. Conduct an initial analysis of the site.
  3. Investigate available utilities.
  4. Determine transportation characteristics and requirements.
  5. Confirm that the desired improvements will be acceptable in accordance with local building restrictions.
  6. Investigate drainage requirements based on the project location.
  7. Investigate any hindrances that would stall the project moving forward.
  8. Prepare a Concept Site Plan

Land development 101

Creativity and common sense are two key ingredients when it comes to Land Development. AEG has both in abundance. We’ll make sure to meet all City ordinances and requirements for your project while keeping you and your desires at the forefront. Successful and efficient Land Development doesn’t need to be a rocky road.

1. Create a Preliminary Plat

  1. After the Due Diligence Process has been completed, we take the client approved Concept site plan and create a Preliminary Plat, complete with property description including proposed lots and streets, initial Drainage Analysis and layout of probable storm sewer system, Wastewater analysis and proposed improvements, and Analysis of water requirements such as irrigation and fire hydrants.
  2. Submit the Preliminary Plat to the City or County for review.
  3. Address all review comments by making modifications and resubmitting for further review.
  4. Upon approval by the City/ County, the process for Final Plat can proceed.

2. Create a final Plat

Based on field surveys, including Boundary, Topographic and Tree, the Final Plat depicts the geometry of the site layout and any public right-of-ways and easements.

  1. The Final Plat must be submitted along with a set of Construction Plans which may, depending on the scope of the project, include:
    • Drainage Analysis of existing and proposed conditions
    • Grading plans
    • Street paving plan and profile
    • Sanitary sewer plan and profile
    • Water plan
    • Storm drain plan and profile
    • Detention pond design
    • Traffic control plan
    • Erosion control plan
    • Detail sheets of city construction standards
  2. Submit the Final plat and Construction plans to the City/ County for review.
  3. Address all review comments by making modifications and resubmitting for further review.
  4. Receive Approval letter from the City/County.
  5. Advertise and award the project to your chosen contractor.
  6. Construction takes place.
  7. Final City/County Inspection of the Public Works Improvements.
  8. Submit Record Drawings
  9. Receive Letter of Acceptance
  10. File the Plat with Public Records
