Title: Protecting Water Quality from Urban Runoff Author: US EPA, OW, OWM, Water Permits Division, Municipal Branch Subject: This fact sheet explains how urbanized areas affect water quality through increased runoff and pollutant loads and what homeowners can do to . SECTION 7 - EROSION AND SEDIMENT CONTROL METHODS June Erosion Control BMPs BMPs for erosion control are measures that have been proven to work on construction sites when they were properly planned and constructed. These measures reduce erosion potential by stabilizing exposed soil or reducing surface runoff flow Size: KB.
The Stormwater Design Manual is compatible with the Minimum Design Criteria (MDC) that are codified in the stormwater rules, which went into effect on Jan. 1, The Stormwater Program will periodically update the Manual to provide better guidance on meeting the stormwater rules. Stormwater Control Measure Credit Document (11/7/): This Phone: Runoff increases in proportion to the impervious area of the site. If less than 5 per cent of a site is paved or compacted, the impact on the quantity of the surface runoff will be negligible. Reducing the amount of runoff also reduces the wash-off of pollutants. Rainwater harvesting can remove runoff from the drainage system altogether.
measures is to prevent or reduce the amount of contaminants released to surface waters; however, the pollutant reduction that can be attributed to these measures has not been quantified (WEF, ). This discussion of non-structural BMPs emphasizes practices to achieve source control, and pollution containment and prevention. Chapter 4: Hydrology Anchor: #i Section 1: Hydrology’s Role in Hydraulic Design. In the context of hydraulic design, hydrologic analysis provides estimates of flood magnitudes as a result of precipitation. These estimates consider processes in a watershed that transform precipitation to runoff and that transport water through the system to a project’s location.

A stormwater management facility (SWMF) is a control measure that manages stormwater runoff and changes the characteristics of that runoff including, but not limited to, the quantity and quality, the period of release or the velocity of flow and may also be called a best management practice (BMP).

versions to divert surface water runoff to temporary sediment traps and temporary sediment ba- sins where the sediment-laden water can be treated.
Most measures illustrated in this section are associated with proper site management. The proper use of BMPs is essential to effectively handle stormwater runoff from construction activities. These practices should be implemented in site-specific SWPPPs to identify and promote stormwater pollution prevention.
Surface Flow Fundamentals. Surface water flow is simply the continuous movement of water in runoff or open channels. This flow is often quantified as discharge, defined as the rate of flow or the volume of water that passes through a channel cross section in a specific period of time.
The practice standards and specifications are guidelines, intended to minimize the time required to design practices for use under typical site conditions. This manual is intended for periodic updates. Therefore, sections of the manual may change as practices for erosion and sedimentation control Phone: such planning.

The standards and specifications apply to lands within New York State where housing, industrial, institutional, recreational, or highway construction, and other land disturbances are occurring or imminent.
INTRODUCTION TO STORM WATER RUNOFF 4 Chapter 1 October Precipitation that reaches the surface of the earth is either absorbed by the soil through percolation or flows overland as runoff.
Vegetative cover enhances absorption by intercepting the rainfall, slowing runoff, and providing root channels that promote Size: KB. The control of sedimentation from construction sites is accomplished through the utilization of a variety of erosion and sediment control Best Management Practices (BMPs).
Essentially, any device, practice, or procedure that has demonstrated to effectively control either the quality and/or quantity of stormwater runoff while maintaining compatibility with the planned land used are classified.
