RE: Rip-rap slopes
(OP)
For a marina project, we have boat slips with 8" to 12" rip-rap on the land side (end of slip). Currently, the rip-rap slope is 1:2. Can we make steeper, say 1:1-1/2, or even 1:1?

1.)Do you have funds to use other materials?
2.)If so, pour a sea wall and use the riprap as a bank stabilizer.
3.)Use Gabions, You can stack Gabions to what ever slope you desire.
4.)Drive sheet pile.
5.)Where I fish we have used interlocking retaining wall stones.
It depends on what your objective is and how much money you want to throw at it.

Although as many posts have noted, 2:1 has become the standard for ungrouted rip-rap, we have had several projects where environmental agencies have conditioned no grouting, and economics have prevented walls. Select placement of the stones to decrease the voids and create effective point-to point contacts will allow steeper slopes. But a larger skeleton size (i.e larger stones), within intermediate filler sizes will be required, with good field control.
