Proposed drainage improvements, Chapter 6, part 2, 1964
On heavily to serve as major flood channels for the Master Drainage System here proposed.  In CHAPTER 5 it was pointed out that these creeks now are capable of carrying only limited amounts of storm runoff, and that channel enlargement will likely be necessary over most of their lengths.  Detailed determination of channel dimensions will come with final design, but from the preliminary studies and the data compiled, estimates of cost have been prepared for proposed right-of-way and construction along these two creeks.  Salt Lake County has had exploratory meetings with representatives of the U. S. Army Engineers, Sacramento District, regarding federal participation in the storm drainage system and in channel improvements for Mill Creek and Big Cottonwood Creek.  The Army Engineers have indicated that the present flood control laws give authority for federal participation in improvements of this nature.  They have promised to review the Master Plan as soon as it is completed and assist the County in every way possible.  With regard to the design of the creek channels for the anticipated future flood flows when ultimate development has taken place over the areas, the Corps of Engineers requires that major flood channels be adequate to pass a 100-year frequency flood.  We have, therefore, based our proposed improvements for Mill Creek and Big Cottonwood Creek with regard to the size of channel and consequent right-of-way required on the channel capacity for a 100-year frequency.  Because of the large volume of water anticipated from a 100-year frequency storm over the tributary area to each creek, it has been found that velocities will result in extensive scouring in the natural channels.  It will therefore be necessary to provide channel lining for the ultimate design flows, Inasmuch as there is no real alternative, no comparative cost studies have been made as part of this report, but it is possible that the saving in right-of-way achieved by lining the channels, 85  will offset the cost of the much wider right-of-way width required to convey the anticipated flood flows in a natural earth channel.  The approximate 100-year flow quantities and the required right-of-way to provide for these flows is as follows: On Mill Creek, the flows will vary from 250 cfs at the mouth of the canyon to 1800 cfs below Interstate 15.  This will require a right-of-way width of approximately 30 feet at Wasatch Boulevard, increasing to a possible width at State Street of 100 feet.  The flows in Big Cottonwood Creek will range from 350 cfs near the mouth of the canyon to 3500 cfs at the Jordan River.  Right-of-way widths along the channel also will vary from 30 to 100 feet.  These figures include an allowance for the normal flows out of the canyons.  If a peak snow-melt runoff coincided with a heavy rainstorm over the valley, greater volumes could be generated than are reflected in the foregoing figures.  However, it is possible that at the time ultimate development has taken place in this portion of the County, storage facilities on the mountain watersheds will have been constructed, as is now being discussed.  This would provide flood control protection for the downstream areas.  Surplus Canal Outflow  In CHAPTER 3 reference was made to the fact that no direct outlet to Great Salt Lake exists for the Surplus Canal.  Also, that from a point just north of North Temple Street to the Goggin Drain diversion at 1100 North, the present improved channel has no slope.  To adequately dispose of the anticipated flood flows in excess of 5000 cfs will require an outlet for the Surplus Canal.  It is therefore proposed to construct additional channel and extend the Canal to Great Salt Lake as shown in FIGURE 11.  The length of new channel required is approximately 8 miles.  It will require a bottom width in the new channel of 200 feet and a total right-of-way 86 of 400 feet.  The design water surface in Great Salt Lake was assumed at elevation 4204.0, which is expected to be the maximum elevation when the Lake is diked off.  The reader will note that the existing right-of-way widths on the Surplus Canal between the dam at 21st South and the end of the Surplus Canal at 1100 North is 260 to 290 feet.  This was based on a flow of 3200 cfs, but in accordance with the previous discussion on the Jordan River, it will be possible to enlarge the Surplus Canal to carry 5000 cfs within the existing right-of-way.  87 ESTIMATE COST OF PROPOSED STORM DRAINAGE IMPROVEMENTS MILL CREEK AREA (NOTE: All total cost figures have been rounded off to the nearest $100.00) SYSTEM “B” ITEM QUANTITY UNIT COST

Transcript On heavily to serve as major flood channels for the Master Drainage System here proposed. In CHAPTER 5 it was pointed out that these creeks now are capable of carrying only limited amounts of storm runoff, and that channel enlargement will likely be necessary over most of their lengths. Detailed determination of channel dimensions will come with final design, but from the preliminary studies and the data compiled, estimates of cost have been prepared for proposed right-of-way and construction along these two creeks. Salt Lake County has had exploratory meetings with representatives of the U. S. Army Engineers, Sacramento District, regarding federal participation in the storm drainage system and in channel improvements for Mill Creek and Big Cottonwood Creek. The Army Engineers have indicated that the present flood control laws give authority for federal participation in improvements of this nature. They have promised to review the Master Plan as soon as it is completed and assist the County in every way possible. With regard to the design of the creek channels for the anticipated future flood flows when ultimate development has taken place over the areas, the Corps of Engineers requires that major flood channels be adequate to pass a 100-year frequency flood. We have, therefore, based our proposed improvements for Mill Creek and Big Cottonwood Creek with regard to the size of channel and consequent right-of-way required on the channel capacity for a 100-year frequency. Because of the large volume of water anticipated from a 100-year frequency storm over the tributary area to each creek, it has been found that velocities will result in extensive scouring in the natural channels. It will therefore be necessary to provide channel lining for the ultimate design flows, Inasmuch as there is no real alternative, no comparative cost studies have been made as part of this report, but it is possible that the saving in right-of-way achieved by lining the channels, 85 will offset the cost of the much wider right-of-way width required to convey the anticipated flood flows in a natural earth channel. The approximate 100-year flow quantities and the required right-of-way to provide for these flows is as follows: On Mill Creek, the flows will vary from 250 cfs at the mouth of the canyon to 1800 cfs below Interstate 15. This will require a right-of-way width of approximately 30 feet at Wasatch Boulevard, increasing to a possible width at State Street of 100 feet. The flows in Big Cottonwood Creek will range from 350 cfs near the mouth of the canyon to 3500 cfs at the Jordan River. Right-of-way widths along the channel also will vary from 30 to 100 feet. These figures include an allowance for the normal flows out of the canyons. If a peak snow-melt runoff coincided with a heavy rainstorm over the valley, greater volumes could be generated than are reflected in the foregoing figures. However, it is possible that at the time ultimate development has taken place in this portion of the County, storage facilities on the mountain watersheds will have been constructed, as is now being discussed. This would provide flood control protection for the downstream areas. Surplus Canal Outflow In CHAPTER 3 reference was made to the fact that no direct outlet to Great Salt Lake exists for the Surplus Canal. Also, that from a point just north of North Temple Street to the Goggin Drain diversion at 1100 North, the present improved channel has no slope. To adequately dispose of the anticipated flood flows in excess of 5000 cfs will require an outlet for the Surplus Canal. It is therefore proposed to construct additional channel and extend the Canal to Great Salt Lake as shown in FIGURE 11. The length of new channel required is approximately 8 miles. It will require a bottom width in the new channel of 200 feet and a total right-of-way 86 of 400 feet. The design water surface in Great Salt Lake was assumed at elevation 4204.0, which is expected to be the maximum elevation when the Lake is diked off. The reader will note that the existing right-of-way widths on the Surplus Canal between the dam at 21st South and the end of the Surplus Canal at 1100 North is 260 to 290 feet. This was based on a flow of 3200 cfs, but in accordance with the previous discussion on the Jordan River, it will be possible to enlarge the Surplus Canal to carry 5000 cfs within the existing right-of-way. 87 ESTIMATE COST OF PROPOSED STORM DRAINAGE IMPROVEMENTS MILL CREEK AREA (NOTE: All total cost figures have been rounded off to the nearest $100.00) SYSTEM “B” ITEM QUANTITY UNIT COST
