ESSEX COUNT Y IN SPRING

RENDERING: INUNDATING CAREFULLY SELECTED SECTIONS OF ESSEX FARMLAND IN SPRING

However, despite the technical
advances, ultimately it was the policy
and financial incentive for municipal
drainage infrastructure that transformed
the landscape. The result for Essex
has been a 97 percent loss of historic
wetlands. Currently, 72 percent of the
land is agricultural, the majority of which
is tile drained.
BLOCKING PHOSPHOROUS
AT ITS SOURCE
The Lake Erie Basin receives 44 per
cent of the phosphorus entering the
Great Lakes. Rather than address the
phosphorous once it is already in the
lake, there is tremendous opportunity
to reduce the phosphorus at the source.
While landscape architects certainly
have the skills to design landscape
infrastructural solutions, the dispersed
nature of phosphorus runoff and limited
capital of farming municipalities, leave
large-scale interventions too expensive
with minimal impact. Designing
for a broad scale often requires an
understanding of the legal and political
landscape that, in many cases, becomes
a more challenging design project.
In Essex County, this places pressure
on individual farmers to apply green
infrastructure and amend their
practices. Real change will hinge on
using policy, incentives, and a knowledge
of the farming economy to design
a regional program that will assist
individual farmers in implementing
strategies without economic loss.

MAKING LANDS WET
ON A BROAD SCALE
Wet Lands suggests that to counter
the effects of centuries long drainage
practices for agricultural land use, we
must make lands wet again. Spring
rainfall events are the most critical
time to prevent agricultural runoff
from entering waterbodies. This can
be accomplished by holding water
on farmlands and within drainage
infrastructure. A series of bermed
fields would be used during the wet
season by pumping nutrient-rich
spring runoff from the municipal
drains - preventing the immediate
entry of nutrient rich water into Lake
Erie. This method allows nutrients to
bond with soil particles over a period
of one to three months, enriching the
soil and cleaning the water: a mutually
beneficial endeavor for farmers and
Lake Erie.
Parametric design offers a dynamic
way of spatially modelling scenarios
and calculating outcomes to adjust for
potential effects and varying numbers
of farmers adopting the suggested
practices. To develop the model,
geographic information systems (GIS)
datasets of property lines, municipal
drains, soil type, and land cover were
exported from ArcGIS into the 3D
modelling software Rhino to work
with using the parametric modelling
plug-in Grasshopper, a visual coding
software developed for users who are
unfamiliar with code.

MAPPING IDEAL SITES
To identify properties adjacent to a
municipal drain for strategic inundation,
a basic Grasshopper script was created
to select all closed curves of the property
lines containing part of a municipal
drain within its boundary. The search
was narrowed by eliminating properties
with small footprints or sandy soil, and
highlighting properties which already
contain wetland or forest cover. This
categorization produced a map of ideal
inundation sites to calculate the potential
area of seasonal wetlands and the volume
of water held within them. 473 sites, equal
to 18,200 hectares of land, were identified
for potential inundation. By pumping
nutrient-rich spring runoff into these
areas for the wet spring season, farmers
would not only enrich their farmlands
and mitigate flooding, they would create
habitat during the peak migratory bird
season while clarifying the drainage
headed for the lake.
This method of modelling is helpful to
understand the scale and effects of
the proposed interventions in reducing
phosphorous in Lake Erie, using measures
such as the volume of spring runoff
that might captured during an average
spring season in relation to land area.
According to our study, if only 25 per
cent of the farms adjacent to a municipal
drain adopted the proposed practices,
41 per cent of the spring rainfall would be
captured and the habitat area available to
migratory birds would increase from 7 per
cent to 16 per cent.
