Two (2) consequences of construction and development are the increased runoff created by the changed properties of the ground surface and the rate of discharge of this increased runoff. These are both of great relevance to stormwater management. The natural condition of the land before development is in relative balance with the natural capacity of the receiving creeks. Normally, the undeveloped conditions provide greater permeability and longer times of concentration. By modification of the ground surface from the irregular, pervious and vegetation-covered, the areas are changed to more impervious, more quickly drained and, in some cases, denuded of vegetation. It is the policy of the City to protect and promote the public health, safety and general welfare. The management of stormwater will reduce the erosion on land and creek channels, will reduce the possibility of damage to public and private property, will assist in the attainment and maintenance of water quality standards and will preserve the environmental quality of the watercourses in the City.

3. 
Bedding Under And Around The Pipe. All pipe shall be bedded in MSD 1 or 2 bedding unless otherwise directed by the City.
4. 
Earth Backfill, Flowable Fill And Jetting. The permissible trench backfill materials and compaction methods and criteria are subdivided into those associated with sewer maintenance and new construction of sewers. All trenches not considered part of new construction as defined below will be backfilled according to the maintenance standards and at the direction of the Director of Engineering or his/her designee.
a. 
Maintenance. Where maintenance/repairs require excavation to existing sewers.
(1) 
Flowable Fill (inside Paved Areas). Where maintenance is required to existing sewers in paved areas, flowable fill will be used as backfill (except as approved by the City) from the top of the bedding material six (6) inches above the pipe to the surface or to within one (1) foot of grade in landscaped areas.
(2) 
Earth Backfill (outside Paved Areas). As an alternative to flowable fill, earth backfill (meeting MSD standards) may be used outside paved areas, from the top of the bedding material six (6) inches above the pipe to the surface. Earth backfill should be placed in maximum eight-inch loose lifts and shall be mechanically compacted to a minimum density equal to that of the adjacent, undisturbed earth.
b. 
New Construction. To include sewer construction in new residential subdivisions, new residential lots and new commercial developments with the exception that any excavations within existing paved areas or any off-site construction excavations are to be treated as a maintenance excavation as stated above.
(1) 
Earth Backfill (Outside Paved Areas). Earth backfill for new construction may be used outside paved areas and must be properly jetted to achieve proper compaction. [See Subsection (A)(4)(b)(4), Jetting, below.]
(2) 
Earth Backfill (Inside Proposed Paved Areas). Earth backfills inside paved areas shall be placed in maximum eight-inch loose lifts and shall be mechanically compacted to a minimum density equal to that of the adjacent undisturbed earth. Prior to paving operations, subgrade must be prepared and compacted to City standards per Chapter 405 of this Code.
(3) 
Granular Backfill (inside Proposed Paved Areas). Granular backfill under proposed paved areas and two (2) feet beyond proposed edge of pavement shall consist of well graded three-fourth (3/4) inch minus crushed limestone. Granular materials shall be free from organic, deleterious or earth materials such as silt or clay. Granular materials must be properly jetted to achieve proper compaction. [See Jetting in Subdivision (A)(4) below.]
(4) 
Jetting. Granular materials and earth materials associated with new construction outside of pavements may be jetted, taking care to avoid damage to the newly laid sewers. The jetting shall be performed with a probe route on not greater than seven and one-half (7 1/2) foot centers with the jetting probe centered over and parallel with the direction of the pipe. Trench widths greater than ten (10) feet will require multiple probes every seven and one-half (7 1/2) foot centers.
(a) 
Depth. Trench backfill less than eight (8) feet in depth shall be probed to a depth extending to half the depth of the trench backfill, but not less than three (3) feet. Trench backfill greater than eight (8) feet in depth shall be probed to half the depth of the trench backfill but not greater than eight (8) feet.
(b) 
Equipment. The jetting probe shall be a metal pipe with an exterior diameter of one and one-half (1 1/2) to two (2) inches.
(c) 
Method. Jetting shall be performed from the low surface topographic point and proceed toward the high point and from the bottom of the trench backfill towards the surface. The flooding of each jetting probe shall be started slowly allowing slow saturation of the soil. Water is not to be allowed to flow away from the ditch without first saturating the trench.
(d) 
Surface Bridging. The contractor shall identify the locations of surface bridging (the tendency for the upper backfill crust to arch over the trench rather than collapse and consolidate during the jetting process). The contractor shall break down the bridged areas using an appropriate method such as the wheels or bucket of a backhoe. When the surface crust is collapsed, the void shall be backfilled with the same material used as trench backfill and re-jetted. Compaction of the materials within the sunken/jetted area shall be compacted such that no further surface subsidence occurs.
5. 
Cast-Iron Covers. Concrete covers on structures will not be allowed. Only cast-iron covers are permitted.
6. 
Joints. All pipe joints and joints on new structures shall use City approved rubber compression type joints. Water stops are required at all points of connection not using rubber compression type joints such as connections to existing structures.

f. 
Creeks. Creeks to be piped under any public road shall be sized to account for a fifty percent (50%) blockage of the pipe for pipes and boxes with a design size (including the percent blocked) up to six (6) feet in diameter. For pipes and boxes six (6) feet and larger, the percent blocked may be reduced at the direction of the Director of Engineering or his/her designee.
2. 
Stormwater Overflow Systems.
a. 
Definition. The purpose of the overflow system is to provide a drainage path to safely pass flows which cannot be accommodated by the design system without causing flooding of adjacent structures.
b. 
100-Year Storm Events. Flood areas shall be evaluated and shown on the plans so that if the designed storm sewers are exceeded by a storm event, the flooded area will contain the 100-year, 20-minute and 100-year, 24-hour event. The depth in parking lots may not exceed eight (8) inches and no part of any flooded area may be within thirty (30) feet of a building. A permanent drainage easement is required for all areas within the flood area of a 100-year storm event and must be recorded on the subdivision plat.
c. 
100-Year Flood Elevation. One (1) vertical foot of freeboard shall be maintained between the 100-year high water elevation and the low sill elevation of any adjacent structure or building.
d. 
Overflow Facilities. Sewers or structures designed as part of an overflow system for flood areas shall be designed for the 100-year, 20-minute peak flows. Where conditions do not allow this, the overflow system shall be considered on a site specific basis by the City Engineer.
