The Riverside Retreat project stands as a hallmark of AXA Engineers’ proficiency in handling complex residential developments situated in flat terrains near sensitive environmental areas. Spanning 149 acres in Pitt County, North Carolina, this project presents distinctive challenges due to its proximity to streams and wetlands. Effective stormwater and wastewater management, along with balancing cut and fill volumes, are essential for the project’s success.
Project Vision and Challenges
The Riverside Retreat is envisioned as a serene residential community that harmoniously integrates with its natural surroundings. The flat terrain and minimal elevation difference between the site and the adjacent stream and wetland areas present significant engineering challenges.
01
Stormwater Management
The arrangement and design of Stormwater Control Measures (SCM) ensure that stormwater flowing into the pond from the storm system is not lower than water surface elevation (WSE) in the pond.
02
Wastewater Management
Located in a low-lying area, the project faces challenges in wastewater management as gravity sewer systems cannot be fully employed to connect with existing sewer manholes.
03
Balancing Cut and Fill Volumes
Ensuring a balance between cut and fill volumes across the project site is crucial to maintaining site integrity and cost-effectiveness.
Strategic Solutions
To address these challenges, AXA Engineers has devised comprehensive solutions:
1. Strategic Placement of SCMs and Roadway Profile Adjustments
To maintain effective stormwater management, SCMs will be placed in low-lying areas near streams and wetlands. This strategic placement ensures that stormwater can naturally flow into the ponds without compromising the water surface elevation (WSE). Additionally, roadway profiles will be adjusted to facilitate proper drainage and balance cut and fill volumes. These adjustments will optimize earth movement and promote site stability.
2. Combination of Gravity Sewer Systems and Pump Stations
Given the site’s low-lying nature, a combination of gravity sewer systems and pump stations will be employed to manage wastewater. This hybrid system ensures that areas unable to rely on natural drainage can still efficiently connect to the existing sewer infrastructure. Pump stations will be strategically placed in low-lying areas to facilitate the movement of wastewater, ensuring compliance with environmental regulations and maintaining hygiene.
3. Comprehensive Earthwork Planning
Balancing cut and fill volumes is essential for the project’s structural integrity and cost management. Careful planning of earthwork operations, including adjusting roadway profiles and strategic placement of infrastructure, will ensure that the site remains stable and construction remains efficient.
