Site restoration - roadsides

Site restoration - roadsides

(OP)
I was just looking through the NYSDOT bid price catalog. Item 610.1601, Establishing Turf - Roadside, is $5/SY. Item 610.17, Wildflower seeding, is too new to have a bid history yet, but the item it replaced averaged $8000/acre, or under $2/SY.

Assuming the wildflowers would mmet the requirements of our SWPPP permit, is there any reason not to specify them?

I must confess that I'm motivated as much by anticipation of the look on the Deputy Commissioner's face when I suggest it as by any potential savings.

RE: Site restoration - roadsides

I doubt wildflowers would provide the level of erosion protection that grass would. Also, you will probably need a specialist to recommend the seed mixture. They usually need to be native seed appropriate to the climate at the site. Might take some time to harvest the seed.

You're probably right. I'd bet there are other groundcovers that would work that are cheaper than grass, but I don't know enough about horticulture to even begin to write a spec for them.

TxDOT used to sow wildflowers on roadsides, then not mow in the spring and summer. It supposedly saved them money and generated tourism. I don't know if they still do that.

RE: Site restoration - roadsides

If they have a spec number for the seed, they probably have a seed mixture in there also. I know MNDOT had seed mixes in the book.
