Landmark Science & Engineering
Providing solutions to all of your land development needs

Landmark Science & Engineering, in operation since 1987, is a successful consulting firm offering fully integrated planning, civil engineering, site design, and environmental services. We are committed to providing the highest quality services with a comprehensive focus on sustainable design practices.

We serve public and private-sector clients in Delaware, Pennsylvania, Maryland, and New Jersey from regional branch offices, where our local knowledge combines with technical expertise and integrated, cost-efficient services.

We achieve success for our clients' municipal, commercial, industrial, institutional, educational, residential, and transportation development projects by applying our expertise in planning, surveying, engineering and design, environmental investigation and mitigation design for wetlands and brownfields.

Sustainable design is incorporated into all aspects of our projects across all market segments, including: ecosystems and habitat design, stormwater management Green technologies, water conservation and "grey water" reuse, wetland mitigation, low impact land planning and design, environmental sciences and permitting, and on-site renewable energy generation.

When a project requires disciplines outside of our areas of expertise, we can assemble and administer a multidisciplinary team of specialized consultants or work as part of a design team assembled and led by others.
