Caledonia City Zoning Code

PRESERVATION REQUIREMENTS

§ 153.240.- SOIL EROSION AND SEDIMENT CONTROL.

The following standards shall apply to all development and activity that necessitates the grading, stripping, cutting, filling or exposure of soils:

(A)

The development shall conform to the natural limitations presented by topography and soil so as to create the least potential for soil erosion.

(B)

Erosion and sedimentation control measure shall be coordinated with the different stages of development. Appropriate control measures shall be installed prior to development when necessary to control erosion.

(C)

Land shall be developed in increments of workable size such that adequate erosion and siltation controls can be provided as construction progresses. The smallest practical area of land shall be exposed at any one period of time.

(D)

The drainage system shall be constructed and operational as quickly as possible during construction.

(E)

Whenever possible, natural vegetation shall be retained and protected.

(F)

Were the topsoil is removed, sufficient arable soil shall be set aside for respreading over the developed area. The soil shall be restored to a depth of four inches and shall be of a quality at least equal to the soil quality prior to development.

(G)

When soil is exposed, the exposure shall be for the shortest feasible period of time. No exposure shall be planned to exceed 60 days. The time period may be extended only if the Planning Department is satisfied that adequate measures have been established and will remain in place.

(H)

The natural drainage system shall be used as far as is feasible for the storage and flow of runoff. Stormwater drainage shall be discharged to marshlands, swamps, retension basins and other treatment facilities. Diversions of stormwater to marshlands and swamps shall be considered for existing or planned surface drainage. Marshlands and swamps used for stormwater shall provide for natural or artificial water level control. Temporary storage areas or retension basins scattered throughout developed areas shall be encouraged to reduce peak flows, erosion damage and construction cost.

(Ord. 164, passed 9-14-1982)

§ 153.241. - TREES AND WOODLANDS.

The following restrictions shall apply to all development:

(A)

Structures and other amenities shall be located in a manner that the optimum number of trees shall be preserved.

(B)

Prior to the granting of a building permit, it shall be the duty of the person seeking the permit to demonstrate that there are no feasible or prudent alternatives to the cutting of trees on the site and that if trees are cut, he or she will restore the density of trees to that which existed before development but in no case shall he be compelled to raise the density above ten trees per acre.

(C)

(1)

Forestation, reforestation or landscaping shall utilize a variety of tree species and shall not utilize any species presently under disease epidemic.

(2)

Species planted shall be hardy under local conditions and compatible with the local landscape.

(D)

Development including grading and contouring shall take place in a manner that the root zone aeration stability of existing trees shall not be affected and shall provide existing trees with a watering equal to one-half the crown area.

(E)

Notwithstanding the above, the removal of trees seriously damaged by storms or other acts of God or diseased trees shall not be prohibited.

(Ord. 164, passed 9-14-1982)

§ 153.242. - WETLANDS.

(A)

To the extent possible, all wetlands including marshlands and swamps shall be retained in their natural state to serve as a stormwater runoff basin and also as a wildlife habitat.

(B)

(1)

No part of any sewage disposal system requiring on-land or in-ground disposal of waste shall be located closer than 150 feet from the normal high water mark unless it is proven by the applicant that no effluent will immediately or gradually reach the wetland because of existing physical characteristics of the site it the system.

(2)

Organic waste which would normally be disposed of at a solid waste disposal site or which would normally be discharged to the wetland.

(3)

Stormwater runoff from construction sites may be directed to the wetland only when substantially free of silt, debris and chemical pollutants and only at rates which will not disturb vegetation or increase turbidity.

(C)

(1)

The lowest floor elevation of buildings if used for living quarters or work areas shall be at least three feet above the seasonal high water level of the wetland.

(2)

Development, which results in unusual road maintenance costs or utility line breakage due to soil limitations, including high frosts action, shall not be permitted.

(3)

The minimum setback for all buildings shall be 75 feet from the wetland.
