Several of us were asked to review the latest plans for the Gorge road improvement project and make our comments today after the trout meeting at Pequest. The division is finally close to beginning work to stabilize the road and improve the parking issues. Lots of ground to cover, so here's my take on the project:
The road will be closed from the bottom up to the RR Trestle parking lot. There will be a gate on the lower end and one immediately downstream of the Trestle parking lot which will effectively close 2/3 of the road to car traffic. Emergency vehicles and stocking trucks will have access via a key.
Beginning upstream first, the current tiny parking lot on the Hoffman's side will see 100' of new asphalt. While asphalt is not the perfect answer, it seems to all to be the best compromise for this short stretch. Proper drainage will be addressed along the entire road, even the closed off areas.
At the Trestle parking area (just below the RR trestle itself), 3 trees will be removed as will that big rock we've all seen cars and trucks get hung up on. Additional parking will be the end result and TU volunteers will plant a native riparian buffer between the lot and the river, explaining what trees and shrubs were used and why in the kiosk.
I think I saw 3 handicapped platforms to be built and several of us expressed concerns over their current design which is wood decking on concrete pillars. We suggested the time-tested platforms that TU's Fred Burroughs/North Jersey chapter designed and built on the Pequest TCA and on the Flatbrook at 3 Bridges. If the division does not adopt these changes, I fear we'll see them tear out at the first flood event. Great to see the division address the needs of the handicapped, whatever design they go with!
On the lower end of the Gorge, new parking will be built to accommodate additional cars and I think 2 more trees will need to be removed (total of 5 as I counted for the entire project). TU volunteers will replant several areas between Trestle parking lot and the lower gate where cars pull in now. We'll see if it is feasible to plant/replace some of the native hemlocks, especially in light of those that have been lost to the Woolly Adelgids. We'd need to make certain the state can get us the beetles that feed on the woolies before we waste time and money on hemlocks. If not hemlocks, then native spruce and/or white pines.
Here is the one area that all of us who know and understand the flooding issues in the Gorge still have major concerns with:
The current plans call for adding asphalt over a several hundred yard stretch beginning at the Trestle parking area and extending upstream past that tight spot where a large rock slab comes down to the current road. We feel asphalt will fail during the first high water event and chunks will fall into the river. Asphalt also emits oils over time and is just not the best choice (at least I don't believe it is). Other engineered products were discussed and I think most agreed that steel-reinforced "porous" concrete could be used instead. At least if the concrete was undermined in a flood event, the division could get back in and shore it up to a large extent. We could also use the porous type that will help minimize additional impervious surfaces.
The next area of concern is the gabions called for along the bank under the Trestle itself. They are clearly under-engineered and would be a mess with the first flood. We made several suggestions as to alternatives.
So that's about the current state of events/design with the gorge road. I hope others who stuck around to review plans and comment will add/correct my post. This has been a long time coming, I hope the division will get it right as I know they certainly want to! With some modifications, we think they can.
