The water runs

The very first water from the solar pump ran the other day and Tommie was there to see it. It's a very satisfying system because you can hear the energy of the sun as the pump has more or less power and you can "see" the sun by the volume of water in the stream, though much delayed.

through the new solar pump system

It was very cute. She immediately called up her brother (who took an interest in the project early on) and held the phone inside the pump house so he could hear the pump wind up with the sun (more power) and down with the clouds (less power)! The solar panels were cranking out 39.6 volts on a mostly clear November day, moving about 800-1000 gallons per hour.


The solar pavilion on the far side of the main retention pond.
It will pump almost twice this volume during the summer months. But there's no battery, so when there's no sun, there's no stream. Unless it's raining, in which case there's still quite a flow!

Here's a little video of the first water running down the creek.

Within a few days of getting the system finished, it rained. And hard. It's easy to forget that this project isn't about making a "water feature". It was about controlling the water because this property was flooding. Last year there was standing water all around the buildings and water running across the driveway. With the work we've done there are no longer an water issues. All excess water after being collected, running the stream, and filling the large 'variable edge' lined retention pond where it can over flow into a restored wetland with a modified outflow (we created a small dam with the glacial till we excavated from the main pond) allowing the wetland to fill up with almost 3' feet of water.  Several hundred thousand gallons.

After the first big rain of 2010, the wetland had about 6" of 
water and the rest of the property had none. Perfect!

Pump House

PASSIVE SOLAR PUMP HOUSE
RECYCLED MATERIALS

A little add on to the solar pavilion was an enclosure for the pump. In all the design work dbBrad and Whidbey Sun and Wind did to get a maintenance/trouble free solar pump and structure, it never occurred to us that with a pump of this type needing to be primed, we would have a freezing issue.

Insulating inside the permanent forms. This insulation's buried about 12" below the top of slab.

It wasn't until we hooked the system for a trial run that I realized water stayed in the pump housing as well as the feeder line. Obviously it was going to need to be protected from freezing. Because I wanted a user friendly (no user required) system, turning valves, draining, priming, flipping switches, etc., wasn't an option.

I used corrugated metal as the inner perma-form (non removable form). It's dark rust color will be better for insulation, absorption of the suns energy which will be stored in the 5" thick concrete walls and slab.

So I did what I do. I gathered a bunch of recycled materials and built a pump house. We designed it to be earth bermed with passive solar heating using lots of insulated thermal mass with long overhangs to prevent over heating in the summer. The old metal window provides access.

Matt finishing up the forms and getting ready to pour concrete.
Materials:
  1. 2x8 scraps left over from FrEdLey -- too nice to throw away but not nice enough for milling;
  2. A bunch of nice T & G 2x6 pine left over from the Mason remodel;
  3. Corrugated steel scraps;
  4. Salvaged flashing;
  5. Rusty re-bar;
  6. An old window;
  7. Damaged insulation contributed by Hansons Building Supply; and
  8. The only purchased item, 24 bags of concrete.
The result is one stout little structure.


The pump house and the solar pavilion

Thermal mass was the objective. We needed to provide enough heat storage to keep the pump from freezing during cold spells. Here on Whidbey Island in Washington state, the weather is pretty mild. We do get snow occasionally but typically when it gets really cold, it's clear. Clear and Sun go together well in a passive solar scenario.

The lower retention pond can be seen beyond with the hybrid steel-wood support for the solar arbor in the foreground and the pump house in the middle.

The pump and the motor are separate pieces mounted together on a plate, all supplied by Sun Pumps. The wiring, plugs, and mechanics of the system were all provided by Whidbey Sun and Wind and went together great. The pond/stream design was by Fran Abel Landscape design and installed by DEW and the Pavilion and Passive solar pump house were designed and built by dbBrad.

Solar Pavilion



The how and the why of a solar pavilion!

Matt and Brad carry the second solar panel towards the creek and pavilion. The first panel can be seen already mounted on the transparent membrane creating a covered outdoor space over by the creek.

My project referrals keep unfolding leading to new projects, with Greenbelt Consulting connected me with these clients -- two wonderful people who have entrusted me to help them make their land right.

The main pond was completed just this summer. When more funds are available we hope to finish planting with the help of Fran Abel Landscape Design. The plants shown were salvaged from areas where we excavated.
On a piece of property at the bottom of a long slope from the Greenbank plateau down towards the west side of Whidbey Island, my clients had built a house and it had a serious water problem. Water flooded their land all last winter.
The stream, looking good, not far after completion.
Phase I was to regrade the topography so water could flow. Phase II was to collect the water and put it in a lined pond with an overflow area and get it operational as soon as possible. We are now in phase III, though the solar pavilion is a bit of an add on!

The upper pond early on. Surface water and water from the residence are collected here.
Collecting the water from the roofs and French drains, we created a lined collection pond, a lined stream, a lined retention pond and an over flow wetland. And though we are just beginning rainy season here in the Northwest, we've had enough over the last 8 months to see that it's working very well. There has been no flooding since we completed Phase I and II


15,000 gallons of water we pumped into the wetland this summer. Absorption was better than 1" per hour.
except when we pumped the main pond this summer to patch a small hole in the liner! We dumped 15,000 gallons of water into the wetland and I was encouraged to see it able to absorb all of this water in less than 24 hours.

Salvaged 5x5 treated fir posts with angle iron corners and pinned connection at top. Large retention pond and solar arbor site visible beyond hoops and perlins.

Of coarse, during the winter it won't be able to absorb so much, so the wetland will get wetter -- way wetter -- and deeper! It's capacity is several hundred thousand gallons which I anticipate it will occasionally need. Most of this water will come via the stream that should actively flow most of the winter.

One of the reasons I love salvaged lumber. To those that recognize it, it's old growth, clear, vertical grained fir. For those that don't, it's what I'd like to call a 'honey' or a 'BAPOW' (Bad Ass Piece of Wood)

During the summer the stream is nice for other reasons as well. It's refreshing and tranquil with the trickle of water, the shimmer of light, the flutter of birds, the croaking of frogs and the buzz of a healthy mix of insects. But, when there's no rain, to have a stream you have to pump the water and that takes energy.

The solar pavilion taking shape. A true wood and steel hybrid structure.

In an effort to make this project 100% green, the clients committed to a solar pump. I immediately suggested we create a solar pavilion to highlight the solar panels and pump rather than use traditional and less attractive pole mounting hardware. Of coarse the structure wanted to be sustainable too.

Looking under the solar panels. The aluminum brackets are mounted to the wood mullions which are sealed with glazing tape to the crystalite and then screwed from below. No fasteners visible on top, save for four holes for the solar feet.

Local steel work, local solar consulting, local wood from my salvage pile, low impact construction with sturdy steel and wood design I'll guarantee remains standing for longer than the life of the solar panels, makes this as sustainable as it can get!

Renovating an old building

In Langley there is an old orange house on a piece of property with wonderful potential for affordable/alternative living which Langley badly needs. It's right on the bus stop, walking distance to downtown Langley, already in an area of fairly high density and with very conscious and community oriented owners. Until such a time as Langley solidifies it's strategy for development, nothing can happen; but in the mean time it couldn't have a better, more fun use, than to be the home of RE-ART. More than any house in Langley, I enjoy driving by this one. Not because it's fancier than the others and impresses the 'Jones', but because it's real, and because it changes. The property is dynamic. Probably the best example of a vacant house that adds to it's community I've ever seen!!


Southwest corner of addition to original building made of salvaged barn wood and telephone tie pieces. It was just about to fall over, had a rotten floor, and was wetter inside than outside.


On the back of this property is a building that was falling apart because the roof was leaking. Leaking roofs, the demise of most old buildings, can cause lots of damage over time. In this building, most of the roof decking on both 'shed' extensions had so much rot you couldn't walk around on them. Even without maintenance, a steeper pitch here would have decreased damage (increased longevity)

The North addition, also added onto the original structure. The roof was too shallow and inadequately framed. As a result, water puddled and created permanent deformation (a sag) in the 2x4 rafters which encouraged more puddling, then leaking, then severe dry rot. (Note to self, why do they call it dry rot if it's always from water damage?)

On the north side open air addition, the original 2x4's (inadequate for a 10' span) had been nailed to the original building's rafter/truss tails. We installed a temporary wall down the middle where the sag was greatest, and the rafters straightened right up. We then slid new 2x4's (crown up) along side these and nailed them to the other side of the rafter tails creating a pair of 2x4's every 24" securely fastened to the original buildings roof and walls. Better looking and twice as strong!


Since the 4x4 posts were off the ground and rotten on the bottom anyhow, we replaced them with pieces 8" shorter. When we knocked the center wall out, the building settled nicely, rotating slightly at the connection between original buildings roof and new rafter pairs. Finally, we went back and put hurricane clips at all the connections.



The South addition gets separated from the original building, cutting out the rotten parts, creating light and allowing us to increase the pitch of the now free standing shed.

The building was one, and now it's two. The shed on the south side, built of salvaged telephone pole cross pieces and barn siding, was very rough and had a roof with not enough slope. Our solution gave it more slope.


The South addition, now separate. You can see the telephone ties which made a great floor and would still be there (no pun intended) if the roof hadn't been leaking for 20 years. The window was twice as wide--I just slid the window to the side, cut the frame with a sawz-all and now there's an insulated window half as big!



We did this at John's suggestion by 'detaching' the buildings. The area we cut out was the area of greatest damage, so it worked out great. When we replaced the multi-piece header with a single salvaged beam, we raised the pitch of the existing rafters by about 5 degrees. This makes all the difference in the world in how it drains. After patching some of the roof decking with salvage pieces from around the property, we clad the top in salvaged metal, also from the property.




The building had an interesting prow. It was a cantilevered beam with a cable running to the back of the structure where a cement block, a cast iron stove part, a few window weights and a crank shaft were all wired together serving as a counter weight for the garage door. Seeing potential for outdoor covered space and additional building protection, we framed the roof out to this point and what a difference that made to the aesthetics. Quite a handsome little building now!



Finally, we sheathed the original building with new 1/2" ply-wood (dbBrad doesn't use OSB), nailed off to 6Perim/8Field and covered with 30# felt. Only a few dollars more per square than 15# and such a better product.

Furniture

The Whidbey Island Arts Council 'studio tour 2010' features 84 artists at 44 locations. dbBrad had furniture at one of the stops, Lois's studio which we remodeled last year.

Turn out was good but sales were not. But with all the happy people, good art, beautiful weather it is really a nice family event.

'The Machine' in Lois's kitchen incorporated contemporary steel counters, an old tractor implement and a ceramic heater housed at the center (not seen in the picture)
I didn't sell much but the response was very encouraging. Everyone loved my furniture and told me they'd never seen anything like it. I get that allot!!

The counter part to 'The Machine', the studio table has the same top and open feel but utilizes flat file cabinets from her mom's old art studio. The pipe were all remnants and the stainless steel legs are from Ikea.
In fact Lois mentioned she thought more people were commenting on her house than on her art. I must say that the thing I heard the most from people was that they loved both.

'2 legged' table is a piece of maple from Rob Hetler's 'not good enough' pile and two steel remnants with my little recycled block and rubber band card holders.

That her house and her art seemed to go together. The timeless architecture of dbBrad with trademark wood and steel and the soft impressionistic natural pastels of Lois's abstract photographs
.

The Captain's Table, so named because the pipe flange base was surplus from Nichols Brothers boat yard via Island Recycling. In the background you can see Lois house with her outdoor art on the recycled steel screens.

And with that the tour was wonderful. Thank you to Lois for letting me show furniture in her driveway and for the extended use of the garage as a shop.


My new and most favorite piece yet, the 'Squalicum Beach Table', this piece of wood was obtained in a creosote clean up, the pieces of pipe were remnants from a previous dbBrad project and the channel was salvaged.
Squalicum beach table. Though the wood has a strong patina, it's very sleek and clean. Because the piece of wood was so heavy, the table tressell is designed to flex enough for the wood to be removed from the steel. No fasteners at all.
Unfinished and awaiting an owner to guide the design of the base, this table is 48" x 96" and features glass insets on woven wire mesh. Leftovers from Island Sash and Door, Chery's Living Gate, FrEdLey railing and candlestick from my dad;s wood pile. In the background the 'Flintstones Table' is visible, with it's 30" wheels and block accessory stools.


Elementary Union Table. Base from Elementary school in Seattle and top from Salvaged Pier Beam on Lake Union.

Squiggly Library Table defies gravity with the wood and the steel seeming to not touch.
DESIGN QUOTE: I am very honest with my (found) materials and pay close attention to what they are and what they want to be. My desire is to change my salvage pieces as little as possible but maintain high resolve in the design/connection.
Brad Hankins is dbBrad.

Tension Table was a fairly successful experiment to use steel in tension and bolts only in sheer. Minimal fasteners on this very strong, but some what top heavy table.



These last two pieces I made several years ago but I'm still very fond of them.

Stream one day, pond the next


Reworking FrEdLey's lower pond.



After draining, the edge had to be cleaned and prep'ed for new work.
With too much liner showing and a concrete retaining wall which wasn't wearing well either, we are draining the pond for re-working.  Even though the liner and concrete wall were underwater when the pond is full, they could be redily seen through the clear water. With good weather and a bunch of new rock, the time had come to fix it.

A 'not so dry run' of new creek.
 At the FrEdLey residence, as with all my ponds, they are  primarily functioning water collector systems, but with aesthetic and habitat features often more noticable.  And when you add Fran Abel Landscape Design into the mix, the aesthetic component becomes so overwhelming that often people don't realize it's a functional and necessary water collection system.

It all starts at the upper pond where we collect the water from all three roofs (242,000 gallons per year) and any surface water runoff. However, with the healthy soil, mulch and bountiful plants, there has been no surface water to speak of since completion of site work two years ago.

Upper pond where water collects.
From the small upper collection pond, the water travels down a stream between the buildings to a larger pond. This larger pond then drains to an adjoining fen or wetland where the water can linger until it is absorbed by the earth.

Everything works and looks great. The reason we're renovating the lower ponds is mostly because of water clarity. It wasn't until this summer that we began running a pump to have water in the stream when it wasn't raining. This water is drawn through a simple filter of PVC pipe with holes buried under pea gravel. Although simple. it works so well that our water has become crystal clear.  Too clear, highlighting more than the fish!


So we've done two things. We've extended the stream up to the vegetable garden so that water from the ponds can be used for irrigation, and we've renovated the edges of the large pond to accommodate varying water levels and to provide more visual interest for viewing as well as a more natural lining for our Koi.


A little lesson in absorbtion.

New stream extension between greenhouse
and upper pond.
 In order to do the work on the lower pond, we had to pump  out most of the water. We pumped the water into our new (still unlined) creek bed over a three day period (it kept refilling with rain!)

Here is what we found. Our pump, by the way is modest, moving only 300 gallons per hour.

On the first day we pumped water for 6 hours lowering the main pond by 18" moving a total of 2200 gallons. Though the new stream is 30' long, only half of it ever saw water. It just vanished into the sand.

On the second, day we pumped water for 3 hours moving 1100 gallons of water. Interesting that the land had lost much of it's ability to absorb water from the previous day's pumping and the entire stream saturated and began to overflow into our upper pond.  One day later, half the water and way less absorption because the soils were already saturated.

On the third day, we only pumped for 2 hours, about 700 gallons and the stream immediately began to overflow.  Absorption had now entirely diminished.
What this says to me is even with sandy soil that appear to initially have superior drainage, watch out! The ground can become saturated quickly.

So even if you have loose sandy soils, if it's saturated and if there's hard pan (clay layer) below and when adjacent compaction prohibits lateral movement, then in floods, onto the streets, into the storm drains and out into the sound.

And shouldn't this water be dealth with on site anyhow? After all, the site was handling the water prior to clearing and building

 At FrEdLey, this was our goal and the pond was designed to have a variable water edge and when it floods, it does so into a controlled wet land (fen) where the water can linger until the ground can absorb it, regardless of what's happening at the neighbors.

Lois's Pond


Water Lily in Bloom. "Even when a project isn't finished, there is beauty in the process if one just takes the time to notice it."--dbBrad


Lois is one of the many artists who participated in the Whidbey Island Arts Council, Open Studio Tour (Sept 25th and 26th). She presented beautiful photos with an impressionistic twist printed on canvas in steel frames, made by dbBrad.

Lois's pond, crystal clear before yesterday's work


Some of the canvas was sealed and hung outside on the metal screens. Her art and the rusty corrugated screens are quite a wonderful combination.

We also put some 'trim' on the yard. The landscaping was never supposed to be part of the house remodel we did last year but, due to groundwater, a landscape plan by Fran Abel, and improvements to how the house relates to the land, we added it to our scope of work.


Stream with liner to catch surface run off and roof water installed over french drain
The pond still needs a little work around the edges. We'll use rocks, plants and wood to shape the stream and hide the liner. 50-100 tour visitors are expected to stop by most studios which will be great exposure for all the artists, and for dbBrad.




Edge work happening along the stream which is also a filter for the Koi Pond

Here's how it all started
When we installed a French drain to mitigate a small stream which ran inside the perimeter of her crawl space all winter. Part of this was from surface water, but most of the water is from her own roof. When we tore off the old poison asphalt torch down roof and insulated a new, installed metal roof, we decided we could no longer dump this water onto the street (day light tight line is Island County standard water control) where it would just run down to the sound.


View from Deck off Lois's bedroom.



We also saw just how much water was generated from the roof so decided to make a pond. It was never intended to be a Koi pond but habitat for wildlife was our second objective to retention. Because of the minimal grade and the surface water we also made a collector stream that receives downspout water and yard water along the entire edge of the house.

Lois installed some color for the Studio Tour
Lois' pond has continued to evolve, but slowly. With very limited funds we've nursed the project along with an hour here and a few rocks there.

But a lot of liner was still showing so we spent a lovely half day in the warm rain of early fall rearranging rocks and plants we had on hand to 'pretty up' for the art tour. We didn't finish and don't have nearly enough plants or rock, but it will look looks much better for the art show and most of the liner is hidden/protected.
