Drivers heading north and south on Interestate 55 through Soulard and Benton Park see grass covered embankments. Every spring the embankments bloom with thousands of bright yellow daffodils. Volunteers plant the flowers. City crews (or are they from MoDOT?) mow the embankments.
The steepness of the slopes on the I-55 embankments look close to the same as those lining the River Des Peres. Unfortunately, the banks of River Des Peres don't look anywhere near as nice as the embankments along I-55 from Arsenal to Gravois.
The ones along the River Des Peres are covered mostly by broken up shards of rock, not trees, green grass, and flowers. Is there anything from a landscape design or soils and erosion control standpoint that would prevent the banks of the River Des Peres from achieving a similar green appearance?
