Have you considered use of an underground Manufactured Treatment Device with
filters? Stormwater360 makes the Stormfilter and Aquashield Inc. makes the
Aquafilter.

They do get large and expensive for large drainage areas, but you can
install a diversion structure to divert the "first flush" to these units.

Need more information.

Source of Nitrogen and Phosphorus?

How tight is tight for real estate?

A modified design for vegetated pond (that I have developed) may be
appropriate, but I do not know the site constraints.

Most important, why is phosphorus and nitrogen leaving the site?

I would be interested in talking about a modified vegetative pond, if I knew
the constraints and the source. It may be unpractical, but worth a thought
for other projects.

I am looking into some alternatives for Nitrogen and Phosphorus
removal from stormwater. Real estate is tight and we're generally
lookign at vaults and piping. A vegetated pond is least desirable due
to the real estate invovled, and groundwater is high such that
infiltration is not likely effective. Are there off-the-shelf
products such as inserts available that can treat generally urban
runoff to 0.5 mg/L Nitrogen and 0.1 mg/L Phosphorus? I've had little
luck locating a simple solution.
