The scope of next year's project is in three phases. In addition to our annual Josh the Baby Otter water safety / literacy project, we are adding two projects to the Little Su River in Houston. During our annual river clean up, this is the area where we end the float and get out of our rafts, kayaks, and canoes. Due to the nature of the riverbank in this area, we have encountered numerous capsizes, endangering volunteers. This project will create a family friendly place to safely launch canoes, kayaks, and rafts. This project will not allow vehicle access, and will not be suitable for powered boat traffic. Some of the tree falling has already been done but there is more to do and the trees that are left are going to be felled w/ the assistance of an excavator. Because of the Covid 19 that interrupted the normal timing of some of our anticipated project work, some of our work that had been planned will now be done at a different time to ensure minimal impact to the river. The water safety interpretive site will be designed to provide a safe place out of the weather to house life jacket loaner board, Josh the Otter Safety material, and perhaps a couple of picnic tables (provided by the city of Houston.)
Last year, Susitna Rotary worked with several entities to obtain permits to proceed with the pavilion project. There was a substantial cost and time for these services but are now completed. With some of the work completed on the land clearing and all the permits in place, and the Covid delays that transpired, it is still the plan for Susitna Rotary to continue with the project as outlined below.
The area (in yellow) we would like to clear is approximately 100 ft long and 50 ft wide. We would like to remove the remaining trees, overburden, and 1/2 of that material. That works out to 740 yds of material. The majority of the trees that we have already fallen were cut up for firewood and used by the local Houston Community residents. We expect to cut the remaining trees into firewood and make it available to folks that need it as proven successful from the first batch. The rest of the clean fill, including stumps can be buried and used to bring up the grade in low spots (in blue) on the same parcel.
We would rent an excavator with a two yard capacity bucket. There are many options available, but average rental rates are $500/ day and $2000/ week. Robert Hall has offered us his dump truck as a donation. 740 yards of material will be accomplished with 74 loads in his 10 yard truck. The material will be transported approximately 200 ft, and I estimate that we could accomplish an average of 10 trips per hour. That would indicate two days of excavator rental to remove the material, and then I suggest another day to prep the subject area for concrete, one day to grade the fill material, and one final day to take care of remaining trees.
In addition to the $2000 excavator rental expense, we should expect to buy fuel at 4 gals / hour for an estimated 160 gals of diesel at $3.00/gal. The excavator will need to be delivered and picked up, and that is normally another $200 each way. We should fill Robert's truck when we are finished, as well ($ 90.)
We'll plan for a 9" concrete slab that is 24ft x 24ft. We can use 16 2" x 10" x 12ft ($19) common boards, We can put #5 rebar ($15.75) on 24" centers both directions, that is 50 pieces.
To protect the water safety interpretive material, I suggest a simple 20ft x 20ft open air pavilion of pressure treated common lumber.
