2 Pound Ln. A customer called in a complaint that every >me it rained, his driveway was flooded from the water coming off the roadway. Driveway

5 16 th Ave. A customer complaint was received that water had been flooding out the storage units and residence on the north side of 16 th Ave.

6 16 th Ave. A water conduc>vity test was performed to determine the exact course of the water, and to what extent it would have to be diverted.

7 16 th Ave. In addi>on, across the road we also had an issue with an exis>ng storm drain. The drain had chronic problems of filling with sediment and debris washed down from the Ashley ditch line. Drain Grate

8 16 th Ave. From the field informa>on gathered, MaP was able to develop a plan for the proposed asphalt berm and swale installa>on.

9 With the help of the Road Crew, we proceeded to install the berm and swale.

12 16 th Ave. Finally we returned to the area and excavated an area at the end of the berm. This area was then refilled with coarse drain rock for the ousall.

Hallgren Dr. The problem is obvious by the picture. On the leu side of the photo there is an exis>ng catch basin which pipes across the road to the west.

13 Hallgren Dr. The problem is obvious by the picture. On the leu side of the photo there is an exis>ng catch basin which pipes across the road to the west. The water is obviously not making it to the exis>ng drain. Exis>ng basin On the right side of the photo there is no drainage, and this pond persists in front of this residence every >me it rains.

14 Hallgren Dr. We u>lized the exis>ng underground piping and excavated an area above it across the road. Underground piping

15 Hallgren Dr. A custom concrete form was constructed to pour a short basin above the pipe. AUer pouring of the basin, the top half of the piping was cut, essen>ally crea>ng another in line basin.

16 Hallgren Dr. AUer comple>ng the basin, we shot grade on both sides of the roadway and hand graded to flow to the basins.

Rolling Hills Ln. A resident was having issues with water shee>ng across the road and being diverted down his retaining wall and onto his property.

17 Rolling Hills Ln. A resident was having issues with water shee>ng across the road and being diverted down his retaining wall and onto his property. AUer surveying the site, it was determined that a berm needed to be installed to divert water down to the corner, where it could be infiltrated into the exis>ng shrub line. Current Water Flow

20 Marilyn Way AUer a heavy rain storm hit the area, several small drainage issues became much bigger ones. This instance on the bike path intersec>ng Marilyn Way, washed the en>re contents of the gravel swale out onto the bike path.

21 Marilyn Way It was determined that a check dam applica>on was appropriate to negate this problem, and prevent it in future heavy rain events.

Vineland Dr. Another chronic problem area that manifested itself auer that rain storm was Vineland Dr. The problem started at the cemetery and expanded as it went toward the golf course.

26 Vineland Dr. Another chronic problem area that manifested itself auer that rain storm was Vineland Dr. The problem started at the cemetery and expanded as it went toward the golf course. Rain water would gain momentum dependent upon storm volume, carrying with it ditch line and roadway sediment. By the >me it reached the storm drains near the golf course, most of it was traveling at such a velocity and volume, it would plug and overrun the drains.

27 Vineland Dr. It was decided that the best way to negate the problem was star>ng at the source of the problem, and slow the runoff from there.

28 Vineland Dr. The project was to remove years of sediment from the ditch line, and install check dams to slow and collect as much runoff as possible. This in effect would eliminate the runoff from the cemetery, from reaching the drains near the golf course.

33 Vineland Dr. The catch basin at the bopom of Vineland, near the golf course, was also an issue. Water would pool on both sides allowing very liple to enter the catch basin, un>l it was almost over the curb line. The road crew came in and cut and removed the surrounding pavement in prepara>on for installa>on of a new curb line. In addi>on, the exis>ng catch basin was to be lowered by 4 inches to allow for beper drainage of the area.

The Ridges While inves>ga>ng eroded patches in the pavement, it was found that this problem was caused by improper sealing of the catch basins to the surrounding concrete

36 The Ridges While inves>ga>ng eroded patches in the pavement, it was found that this problem was caused by improper sealing of the catch basins to the surrounding concrete curb. While only one curb was in need of replacement, all of the catch basins in the next few slides were in need of repair from the inside to stop the problem from progressing.

47 Florence & Rolling Hills The pipe to this drywell at the intersec>on was not properly grouted and sealed into the drywell. As a result, the underlying base rock around the structure and under the pavement, was eroded away. The problem was repaired by cu_ng out a pavement patch and cemen>ng the pipe into the structure.

50 Greenbelt Trail This storm manhole had been paved over and was crea>ng a trip hazard on the walking path due to the pavement sepling. In addi>on it is impossible to inspect this structure in this condi>on. A simple addi>on of risers and repaving around the structure took care of the problem.
