  • Drainage Design

Drainage Design

Drainage plans are required by most municipalities as part of a building permit application or by NYSDEC/Town Wetlands for an environmental permit. Our expertise extends to:

  • Drainage plans for municipal, DEC, and wetlands board permits
  • High groundwater drainage techniques including shallow retention systems, gravel beds, and french drains
  • Areaway and lightwell draining

  • SWPPP’s

SWPPP’s

The owner/operator of any NYS construction project that will involve soil disturbance of one or more acres must obtain coverage under the State Pollutant Discharge Elimination System (SPEDES) General Permit for Stormwater Discharges from Construction Activity. DAE helps identify when a Stormwater Pollution Prevention Plan (SWPPP) is required and guides you through the entire process. This includes:

  • Stormwater Pollution Prevention Plan preparation
  • SWPPP management through MS4 acceptance and DEC approval
  • SWPPP inspections

How We Help Make Your Project a Success

Our dedicated civil engineering team works expertly with residential and commercial projects to integrate solutions for complex site concerns. These services leverage cutting-edge tech and comprehensive team support to emphasize industry standards and success. These capabilities are integral to our civil engineering projects:

3D Modeling & Analysis

We utilize Civil 3D to create 3D site plans for better accuracy and coordination throughout the entire site. This technology creates virtual replicas of physical assets and systems, simplifying the visualization of specific civil engineering services and large-scale infrastructure projects.

Collaboration & Communication

Our civil engineers work closely with architects, owners, and designers, from creating individualized design criteria to customized engineering approaches that ensure a practical design inline with every project.

Innovative Approach

Work with a civil engineering team experienced in leveraging various non-traditional materials and analysis processes that accommodate even the most challenging site conditions in an environmentally conscious manner.

Construction Experience

Backed by real-world residential and commercial construction experience, our civil engineers are familiar with robust challenges faced in the field. From comprehensive site visits to local permit know-how, we ensure your project is the best and most sustainable solution to any complex problem.

"DiLandro Andrews Engineering was indispensable in the civil engineering of an onsite wastewater treatment system. This septic system is located in an environmentally sensitive bay front location of our beach club. As a result, a state of the art system was needed to replace a 55 year old cesspool. As a further constraint, the system is located under an active parking lot where space is a premium. DiLandro Andrews worked tirelessly through multiple evolutions in requirements by the County Department of Health and our Club. Turnarounds and responses were executed on a same-day basis. In the end, they delivered a perfect solution. We feel confident in saying that less talented engineers would have failed to deliver a solution given the regulatory and practical demands of the site. We strongly recommend DiLandro Andrews for any commercial onsite water treatment system project in Suffolk County. You will need professional talent and perseverance, and they provide it every step of the way."
