  We explore the environment of a combined set of $367$ grand-design and $619$
flocculent spiral galaxies. We introduce a novel estimator called the
\textit{local geometric index} to quantify the morphology of the local
environment of these $986$ spirals. The local geometric index allows us to
classify the environment of galaxies into voids, sheets, filaments, and
clusters. We find that grand-designs are mostly located in dense environments
like clusters and filaments ($\sim 78\%$), whereas the fraction of the
flocculents lying in sparse environments like voids and sheets is significantly
higher ($ > 10\%$) than that of the grand-designs. A $p$-value $<$ $10 ^{-3}$
from a Kolmogorov-Smirnov test indicates that our results are statistically
significant at $99.9\%$ confidence level. Further, we note that dense
environments with large tidal flows are dominated by the grand-designs. On the
other hand, low-density environments such as sheets and voids favor the growth
of flocculents.
