Ramp Construction


Here is the coping after the ramp was completed. Sitting perfectly and secure between decking and masonite.

Here is the layout of the 4 quarter pipes and the 2 flat sections. 2x4s used in the flats and 2x6s used in the transitions.
Here is the genius design of Jeff and Jim. This is when you need some nice construction gear. Its just not possible with a skill saw. There was another 2x6 placed behind these two studs but wasn't cut at the angle (you can see the screws on the side holding it).
Here is our first step. The transition was a 7'2" radius and is 3'8.5" tall (we just cut the full plywood sheet).

Here you see the thread from the u-bolt (clothesline bolt) coming out of the 2x6. We drilled 6 holes in each coping (2 3/8 inch Outer diameter used black pipe) and then stuck the hook end of the u-bolt in the holes. Once we drilled the holes in the 2x6 we just stuck the threads right through. On this side we placed a large square washer, a large round washer, a locking washer, and two nuts. Boo-yah. The coping isn't going anywhere.
The decking is beveled to meet the coping perfectly.

We placed the first two layers of 3/8 inch plywood horizontally on the ramp and made sure every seam had at least one 2x6 underneath it. We offset the second layer of plywood to make sure the seams did not double up.
Here you can see the underside of the decking. 2x6 and 3/4 inch plywood. You can also see that the entire ramp is placed on 12x12 concrete blocks.
The finished product.

Decibel Scale of Common Sounds

CHECK IT OUT HERE:
Motorcycle, power lawn mower, garbage truck - 100 DB
Diesel Truck, urban street - 90 DB
Garbage disposal, dishwasher - 80 DB
Freeway traffic at 15 M, vacuum cleaner - 70 DB
Skateboarding 55-65 DB at 50 feet (see study below)
Conversation in restaurant, office, background music - 60 DB

Check out this quote from HERE:
"A noise meter reading conducted by the former Director of Safety at TRW showed skate parks to be the same as or quieter than swimming pools when comparing decibel levels."
"It was also reported that there are 16 million skateboarders in the US compared to 9 million registered little leaguers."

Another study done HERE:

"The result of a rider hitting the nose or tail on another hard surface creates a sound that one might compare to the short instantaneous sound a baseball makes when hit by a bat Instantaneous sound levels for an individual skateboard making the tail popping type of sound range from approximately 65 to 71 decibels (dBA Fast) at fifty feet. This sound is very short in duration and easily controlled by the use of any basic barrier or obstruction."


"One of the goals that modern skateboarders attempt to achieve is sliding along metal surfaces in the skateboard park on their trucks. The noise can best be described as a metal grinding type of sound. Imagine rubbing two pieces of steel together. This sound can be minimized by pumping in a sand like substance into the actual metal pipes that the skateboarders ride over. r The sand or some other resilient material limits the ability of the metal to resonate sound into the community. A little engineering work up front can help to virtually eliminate this source of sound from being a concern. This sound ranged from 54 to 63 decibels (dBA Fast) at fifty feet."


"The loudest sound level predicted above is 65 dBA. This sound level is comparable to the level of a moderate conversation between two individuals. Average conversational levels have been noted in my experience to range from 59 ABA to 63 dBA."

And check this out from HERE:
"a similar study from an October 20, 2006 newsletter of the LifeTips Web site found the following: "One of the most common misperceptions about skate parks is that the noise created by their users will surpass code limits and upset the community. But the reality is quite different. In a recent study, it was found that peak skate park noise levels averaged 70 decibels from 50 feet away. In comparison, from the same 50 feet away a dishwasher and toilet produce comparable decibel levels. A football game produces 117 decibels, heavy traffic 85 decibels and a home refrigerator 50 decibels. All in all, a skatepark is no more noisy than similar recreation areas like a basketball court or children’s playground" (LifeTips 2006)."

An example case in Kern County

SUMMARY OF PROCEEDINGS DIRECTOR'S HEARINGS Conference Room Date: January 18, 2007

Hearing Officer: James E. Ellis Staff: Kathe Malouf Kern County Roads Department: Warren Maxwell

The hearing convened at 10:00 a.m.

Mr. Ellis explained the purpose of the hearing and appeal procedure; noting that existing zoning determines the use of the property and the density; and the hearing is to ensure that development is in accordance with Ordinance and PD standards.


5. Consideration of violation findings – 6625 Dogwood Avenue, Lake Isabella – Categorically Exempt, Section 15303(e) – Debbie Herrera

The applicant was not in attendance; however, had informed Staff prior to the hearing that she would be unable to attend due to her work schedule. Mr. Ellis stated he had reviewed the request and would allow the retention of the skateboard ramp during the processing of the conditional use permit; however, he would allow the skateboard ramp to be used no more than one hour per day and used exclusively by the applicant’s son.

There being no one else wishing to be heard, pro or con, hearing closed. The Hearing Officer approved the retention of the skateboard ramp while formal land use approval is being sought (Notice of Decision #10-07) subject to the submittal of surcharge fees and a signed Acknowledgment of Land Use Violation document that will allow adoption of the findings.

Meeting adjourned at 10:45 a.m.
