Maintain Site-BasedStormwater Detention Systems

Issue:Site-based stormwater diversion anddetention systems must be properly maintainedto be a reliable component of the citys storm-water infrastructure.

Recommendation:Establish maintenance standards for site-basedstormwater systems, and require property owners toverify compliance.

Encourage InnovativeStormwater Practices

Issue:Modern stormwater control systems incorporateboth civil engineering strategies, such asunderground detention tanks, and landscape-based strategies, such as green roofs and naturallandscaping. New York Citys regulations, however,do not properly account for the impact oflandscape-based strategies.

Recommendation:Revise stormwater regulations to account forlandscape-based strategies.

Collaboration: Feature Requests

Incorporated Requests:

1. Bases for columns2. Parameters: number of columns; ratio of opening toenclosure; variable column radius; column radius linked

to height3. Larger openings for shorter columns (to reflectincreased drainage to these columns) --In progress--

Water Quality Volume: amount of water that must beretained for 24 hours to improve stormwater conditions

WaterQualityVolume = P*Rv*A/12P = 90% Annual Rainfall Event number (1.3)

Rv = Runoff = .05*.009*Percent Impervious CoverA = Acres (or ft2*43,560sf/acre)

User Guide

1. Instantiate the powercopy (cgs2132RainRoofPC3)from the catalog:

four input pointsone reference plane

The relative positions of the points is important - take

note. The reference plane should be normal to the surfaceon which you are instantiating, with the normal pointingupward from the surface (up from the roof panel).

2. Execute the knowledge patterns contained in the PC.

3. After adjusting the parameters, run the knowledge pat-terns again.

Basic types of parameters:1. Four input points (can be changed and moved out ofplane)2. Global Parameters (executed using knowledge patterns)3. Local Parameters (parameters of individual UDFs canbe changed)

Outputs:The volume of water collected/retained and the weight ofthe components can be used to drive additional elements.
