Vernal pools are temporary pools of water. Most pools are dry for at least part of the year and fill with the winter rains or snowmelt. This habitat relates to the infiltration pits featured in our stormwater management system. Like a vernal pool, the level of moisture present will vary dramatically throughout the year, however standing water will not occur.
Flora: Vernal pools are home to many endemic species because of the unique environmental niches created. Different species are suited to different moisture levels, and as water evaporates from the edges of a pool, rings of flowers blossom around it. The color patterns change as the wet season wears on. The rings may form swirls and layers, with the green of new grass surrounding the whole pattern.
Flora commonly found at vernal pools include Downingia and lupine species, yellow pansies, several sweet-scented clovers, a variety of goldfields, button parsleys, yellow and bright lavender monkey-flowers, star lilies, yarrow, and endangered grasses such as Solano grass. A large number of rare, endangered species, and endemic species occur in vernal pool areas.

Vernal pool flora best suited to the project’s environment:
Large leave lupine (lupinus polyphyllus).
Ecology: moist to wet open habitats, stream side, wet meadows, disturbed sites
Other Notes: Fix nitrogen and fertilize poor soils
Small-flowered lupine (lupine polycarpus).
Ecology: open, gravelly and sandy sites at low elevations
White clover (trifolium repens).
Ecology: disturbed sites (field, roadsides), low to sub-alpine elevations
Springbank clover (trifolium wormskjoldii).

Chickweed monkey-flower (minmulus alsinoides),
Ecology: vernally moist, often shady, mossy ledges, cliffs, rocky slopes, found mostly at low elevations
Other Notes: annual herb
Yellow monkey-flower (mimulus guttatus).
Ecology: wet ledges, crevasses, weeping rock faces, seepage areas, along streams, near springs, gravel bars, wet ditches and clearings, common from lowland to high elevation
Other notes: annual (fibrous roots) or perennial (from creeping stolons)
Pink monkey-flower (mimulus lewisii).
Ecology: common in and along streams, especially cold ones, wet clearings, forest in avalanche tracks, mid to high elevations
Other Notes: perennial
White fawn lilies (erythronium oregonum).
Ecology: well-drained ,open often grassy areas, open to fairly dense, rocky woodlands, low elevation
Other notes: perennial herb
Yarrow (achillea millefolium).
Ecology: on dry to moist, well drained, open sites, meadows, rocky slopes, gravel bars, roadsides, open forest, low to high elevations, often weedy at lower elevations, common and widespread
Other notes: possibly too invasive for this application

Readers- Please let us know if you have additional information of interest regarding the plants above (invasive species, non-hearty plants, etc.).
Other plants of interest:
Musk-flower (mimulus moschatus).
Ecology: stream banks, moist meadows, rocky seepage area, thickets, road sides, other moist shaded areas, low to mid elevations
Other notes: perennial
Fern (cystopteris fragilis).
Ecology: cool, moist to dry, often calcium rich, rocky forest and openings, rock cliffs/crevasses/ledges, talus slopes
Maidenhair Fern (adiantum pedatum).
Ecology: shady, hummus-rich sites, and moist often rocky forests, on steam banks, cliffs, and in the spray zone of waterfalls

Comfrey (also comphrey) is an important herb in organic gardening, having many fertilizer and purported medicinal uses. Comfrey is a particularly valuable source of fertility to the organic gardener. It is very deep rooted and acts as a dynamic accumulator, mining a host of nutrients from the soil. This plant is present on the proposed installation site, and may be incorporated into the design.

Monthly inches and hours given are averages over a 50 year period.
January: 7.9in / 143hrs = .055in/hr
February: 5.5in /112hrs = .049in/hr
March: 5.3in /118hrs = .045in/hr
April: 3.1in /73hrs = .042in/hr
May : 2.3in / 54hrs = .043in/hr
June: 1.4in /32hrs = .044in/hr
July: .5in / 9hrs = .055in/hr
August: .9in /16hrs = .056in/hr
September: 1.4in / 25hrs = .056in/hr
October: 3.6in /65hrs = .055in/hr
November: 7.5in /126hrs = .057in/hr
December: 8.3in /140hrs = .059in/hr
Site A: Peak stormwater volumes accumulated in 1hr from the Urban Garden ceramics shed roof.
Roof area = 150 sq ft
Average Peak Volume (December) = .059in/hr = .036gal/hr
Max Recorded Volume = 1.14 in/hr = .71gal/hr
Surface Area of Roof X volume of stormwater gives:
AVERAGE 5.52gal/hr = .09gal/min
MAX RECORDED 106.59gal/hr = 1.78gal/min
Site B: Peak stormwater volumes accumulated in 1hr from the Urban Garden potting shed roof.
Roof area = 288 sq ft
Average Peak Volume (December) = .059in/hr = .036gal/hr
Max Recorded Volume = 1.14 in/hr = .71gal/hr
Surface Area of Roof X volume of stormwater gives:
AVERAGE 10.59gal/hr = .18gal/min
MAX RECORDED 204.48gal/hr = 3.41gal/min

Stormwater drainage system and infiltration bed in context
your efforts and designs are a great contribution to the urban farm, and will certainly inspire people to think creatively about storm water. I also think that this type of intervention could become a eugene vernacular. I also love your integration of the system into the landscape, and it is good to see that the design involves other improvements to the site.
ReplyDeleteIt is interesting that your systems are made of commonly available building materials and can be adapted to work on small structure. When I walk the alleys of eugene i can imagine the array of garden sheds, garages, and small structures with these type of whimsical creations. I would encourage you to reach out to the community in the form of workshops, or other displays of your creation. The BackYard Farmer may be a good place for you to display your work.
ReplyDeleteThe issue of regulating water flow to the planted vessels is an are that could use a bit more research as I am not sure how you are going to control the flow of water in large and small precipitation events. Lets set up a meeting at the farm to discuss this further..
i curious to see how you solve this problem.
great work!!!!!!!!!!!!
