§ 36-9-27-68 — Urban drains; duties of county surveyor

The county surveyor shall perform the
following duties with respect to all urban drains within the county
surveyor's jurisdiction:
(1) Prepare and make available to the public design standards of
rainfall intensity and frequency for urban land, design standards
of storm water runoff for urban land, or both. In preparing these
standards, the county surveyor shall consider official weather
bureau information, design criteria of the Indiana department of
natural resources, the published recommendations of the United
States bureau of public roads, and all available local,
topographical, geological, and statistical information that may
affect the design standard of runoff from urban land. The county
surveyor may give special consideration to those weather events
in which rainfall occurs under conditions when soil tends to be
impervious due to frost or other natural causes.
(2) Prepare hydraulic calculations for the channel design of the
urban drain, taking into consideration hydraulic gradients, friction
factors, dimensions, and other engineering variables.
(3) Design the channel or dam required for the urban drain,
including any necessary rerouting and taking into consideration
the structures and structural characteristics of the soil.
(4) Furnish design information for all new drainage structures
(including local flood control dikes) that may be needed to
properly drain urban land or impound water in a small lake in the
most efficient and economical manner.
(5) Keep available maps, listings, or other information showing
current land use and projections of future land use in the area
affected by the urban drain. In preparing this information, the
county surveyor shall consider recommendations of state and
local planning agencies, plan commissions, zoning boards, and
similar bodies.
(6) Include in the county surveyor's report to the board on the
construction or reconstruction of an urban drain the county
surveyor's recommended designation of each parcel of affected
land in the watershed of the urban drain as either urban land or
rural land.
