Question

explain the general steps in stormwater management design from existing conditions (pre-development) through post development.

Answer 1

The general steps in stormwater management design include assessing existing conditions, developing goals, designing stormwater controls, preparing construction plans, implementing controls, and inspecting and maintaining the controls.

Step-by-step explanation:

The general steps in stormwater management design from existing conditions (pre-development) through post development include:

1. Assessing existing conditions: This involves gathering data on the site's topography, soil types, and hydrological characteristics to understand how stormwater currently flows and is managed.
2. Developing stormwater management goals: Based on the assessment, goals are set for managing stormwater, such as reducing runoff volume, promoting infiltration, or preventing erosion.
3. Designing stormwater controls: Strategies and practices are selected and designed to achieve the goals, such as bioswales, detention ponds, or rain gardens.
4. Preparing construction plans: Detailed plans and specifications are created for the implementation of stormwater controls, including layout, materials, and dimensions.
5. Implementing stormwater controls: Construction of the designed stormwater controls takes place, including excavation, installation of infrastructure, and planting vegetation.
6. Inspecting and maintaining stormwater controls: Stormwater controls are periodically inspected to ensure they are functioning as intended and are properly maintained to prevent clogging or failure.
