Ponder This Traditional Cache
Pearbro: No, I no longer work nearby, but I did get another job after shutting down the pond business over a year ago. Due to the feature no longer running and problems with maintaining the cache, I have decided to archive the cache. Thanks to all of those who visited over the years.

Beautiful AND Functional, you can have it all! This incredible water feature has eye-popping, traffic-stopping beauty.
Located on the street-side wall of a warehouse location, it is being enjoyed by all. Feel free to hunt around during business hours. The cache owner, "Pearbro", works inside the pond supply warehouse. This project was designed to divert the roof runoff through a constructed wetlands system, filtering it through the rocks, gravel and wetland plants as it pours over the enchanting falls and into what appears to be a small pool. Actually, the retention basin connects to the other side of the sidewalk so that in a rain event, even more water can be contained and filtered before returning to the environment. The overflow from the lower wetland runs into a rain garden, which is a filter in and of itself. The rain garden facilitates peculation and ground water recharge to the areas aquifer.
Heavy-duty underlayment was used to line the upper wetland due to the use of railroad ties to build up the height of the wetland to facilitate larger cascades. 45-mil. EPDM rubber liner was used throughout the whole project excluding the rain garden, which wasn’t lined due to its function in percolating rainwater. 8 ½ tons of gabions were used to fill the wetlands, 7 tons of mixed ¾ -1 ¼ River Wash Cobble were used to over fill the Gabions in the wetlands and also for the steam and cascades, and a total of 20 tons of Fieldstone Moss Rock as the feature rock for the feature. That’s 35 tons of rock and gravel! The single largest bolder was ?
The filter system is rather unique to this project in that 2 roof drains were diverted through both wetlands. The roof drains capture water from a total of >2500sq. ft. of surface area. The wetlands incorporate the Snorkel and Centipede Modules to facilitate the filtering of the water and the removal of suspended solids from the roof drains. Both wetlands are planted with a large selection of wetland plants designed to not only filter the water (by removing nutrients, pathogens, heavy metals, trace organics), but also to demonstrate the different verities of plants available for wetlands. The feature is run using a 3000 and 4500 gallon per hour pump which are useful in demonstrating 3 different flow characteristics.
This whole project was constructed in 2 days as an advanced pond/waterfall building class attended by contractors from around the state and taught by some of the best builders in the nation.
The site can be visited day or night. Parking is available. Bike, wheelchair, dog, kid friendly. There is a bench for sitting and pondering or having lunch. After dark, the waterfalls are lighted but very late, the pumps and lights shut off until the morning.
This is a featured site on the annual Parade of Ponds benefiting Hospice Caring Project.
GPS jumps around alot because of building and trees, so use the hint if you need.
