Engineering / Stormwater
Polluted stormwater runoff is commonly transported through Municipal Separate Storm Sewer Systems (MS4s), from which it is often discharged untreated into local water-bodies. To prevent harmful pollutants from being washed or dumped into an MS4, operators must obtain a National Pollutant Discharge Elimination System, (NPDES permit), and develop a stormwater management program.
- Phase I, issued in 1990, requires medium and large cities or certain counties with populations of 100,000 or more to obtain NPDES permit coverage for their stormwater discharges.
- Phase II, issued in 1999, requires regulated small MS4s in urbanized areas, as well as small MS4s outside the urbanized areas that are designated by the permitting authority, to obtain NPDES permit coverage for their stormwater discharges.
- Generally, Phase I MS4s are covered by individual permits and Phase II MS4s are covered by a general permit. Each regulated MS4 is required to develop and implement a stormwater management program (SWMP) to reduce the contamination of stormwater runoff and prohibit illicit discharges.
- These regulations were developed to ensure compliance with the federal Clean Water Act and work to increase the number of water bodies that can safely be used for swimming and fishing.
Design Standards, Construction Specifications and Standard Details
The City of Ozark Engineering department has developed engineering design standards, construction specifications, and standard drawing details for public improvement projects. All of these documents shall be used as guidelines for design and construction of public improvements within the City of Ozark. See a copy of these documents.
ReviewThe City of Ozark Engineering department is included in the review process for all site plans, plats, annexations requests and construction plans to ensure compliance with design requirements and to evaluate for potential issues.
CoordinationThe engineering department provides necessary coordination between engineering consultants, utility providers, developers and property owners during the construction phase.
Construction InspectionsDuring construction, the engineering department staff makes periodic inspections to check the quality and reliability of the work in progress. The City of Ozark requires developers to provide a minimum of 24 hours notice for inspection of all work items requiring notification, including but not limited to water/sewer connections, placement of fill, road subgrade/base, curb and gutter forms, curbs and gutter, road paving, sidewalk forms, sidewalks (includes driveway aprons) and drainage structures prior to backfilling as well as stormwater management facilities.
Acceptance of Public ImprovementsAfter the completion of construction and approval of public improvements and record drawing approval, the engineering department initiates the process for acceptance of the installed improvements once the following conditions are met:
- Public Works certifies that the improvements are complete and comply with the Construction Documents requirements, the final plat is approved and the developer has posted the maintenance bond, initiating the 1 year warranty period
