BMP Optimizer VA v2.0 – This easy-to-use software will first simply and graphically solve the Virginia Runoff Reduction Method for New or Redevelopment Sites. You enter in the site characteristics and catchment data, then graphically place your BMP(s) and the runoff and phosphorus reductions are calculated. In addition, it can use the input information and your preference of performance metrics to evaluate the optimal solution of BMP(s) that will satisfy these criteria, including treatment trains of BMPs.
This short video will describe the features of the BMP Optimizer VA v2.0:

- Full compliance with Virginia Runoff Reduction Methodology
- Easy to use graphical interface improves upon VRRM Spreadsheets to allow visual tracking of complex BMP treatment trains
- Ability to evaluate millions of BMP combinations in a matter of minutes
- Objective, repeatable results simplify the review process by balancing regulatory compliance with other important criteria
- Ability to identify installation and maintenance costs as optimization parameters
- Can export all design and site parameters directly to VDEQ VRRM Spreadsheets
The BMP Optimizer allows its users to specify the total number of proposed stormwater BMPs, along with their proposed linkages and contributing land area characteristics, to arrive at an optimized configuration that achieves compliance with Virginia Runoff Reduction Methodology while also considering physical site constraints and user-specified optimization parameters such as installation and maintenance cost. But, do you really need software to identify the right BMPs for your projects? Let’s do the math…
Consider various development scenarios for which you are seeking to evaluate BMP options to meet phosphorus removal requirements.
- Installations may be singular, stand-alone BMPs or combinations of BMPs in series (“treatment trains”)
- The site may have one or more distinct outfalls and each outfall may receive runoff from multiple contributing drainage areas (CDAs)
- To keep the math simple, let’s assume that we only have 10 competing BMP options (in reality, Virginia DEQ recognizes nearly 30 different BMPs!).
For the simplest scenario we’ll consider a single outfall with only one CDA. We only have 10 possible solutions, i.e. the 10 available BMPs. That’s a manageable number, and approachable in terms of thoroughly evaluating each option and objectively identifying the best one. What happens if we keep a singular outfall but now say that the outfall has two separate CDAs? Would you believe that we now have 100 possible BMP configurations? Probably need to plan on working through lunch to get through all of those, but it’s still reasonably possible. If we were to look at a more complex site with 2 outfalls comprised of 3 CDAs each, we now have 1,000,000 possible BMP combinations! The inclusion of a fourth outfall or finer scale CDAs can easily push the number of possible BMP configurations beyond a billion. Could even the most dedicated site engineer be expected to evaluate a billion or more possible BMP combinations to identify the single best configuration among all competing options? And if so, could it be done objectively or would the designer’s past experiences bias the selection?
The most common scenario is that engineer is challenged with employing his or her best balancing act to identify a design that:
- Meets regulatory compliance
- Minimizes cost for the client (Installation? Maintenance? Both?)
- Considers all relevant physical site constraints
- Is constructible and regionally and aesthetically appropriate
Further, the engineer is almost always facing this balancing act under time constraints that preclude thorough evaluation of the numbers of competing options of the magnitude described. Thus, the engineer understandably relies on past experiences and biases to, necessarily, achieve regulatory compliance while often neglecting to adequately consider other important criteria. While this incomplete evaluation process is occurring, and until the engineer arrives at a solution that meets regulatory compliance, time is wasted evaluating options that are discarded as invalid. Further, a solution may be identified that meets regulatory compliance but ends up being prohibitively costly for the client over the BMP life cycle. Or, perhaps the engineer’s biases conflict with those of the review authority and the plan review process is delayed. The BMP Optimizer is capable of addressing these and other issues to improve upon and expedite delivery of your designs.
