Summary

Olmsted County's zoning code bars placing any structure on a significant historic site within the shoreland overlay in a way that affects the site's value, unless the county has removed and documented adequate information about the site in a public repository first. The rule reaches only unincorporated shoreland, not city historic districts.

These county ordinances apply to unincorporated areas of Olmsted County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

3. Significant Historic Sites: No structure may be placed on a significant historic site in a manner that affects the value of the site unless adequate information about the site has been removed and documented in a public repository.

Full Breakdown

14(F)(3) of the Olmsted County Zoning Ordinance protects significant historic sites inside the Article IX Shoreland Overlay District, the regulated strip near public lakes, rivers and streams in unincorporated Olmsted County. 10 for any building, building addition, deck, sign or sewage treatment system in shoreland. 04 reaches only land outside incorporated cities, this protection applies in county-zoned shoreland, not inside Rochester, Stewartville, Byron, Oronoco or the county's other cities, and the county itself administers zoning directly in only Eyota, Marion, Oronoco and Quincy townships; the remaining townships plan through the Township Cooperative Planning Association or their own codes.

10 permit application before ground is disturbed. 10, with each day of a continuing violation charged as a separate offense, and the County Board or Zoning Administrator can seek injunctions, corrective orders or after-the-fact permits in addition to prosecution.

Violations & Fines

Building, adding to, or altering a sewage system on a significant historic site in shoreland without documenting the site first is a misdemeanor under Sections 3.08 and 3.10 of the Zoning Ordinance. Each day the violation continues counts as a separate offense. The Zoning Administrator or County Board can pursue prosecution, fines, injunctions, corrective-measure orders, or require an after-the-fact permit, and flood or shoreland violations are also forwarded to the DNR Commissioner.

Frequently Asked Questions

Does this rule apply inside Rochester or Stewartville?
No. Section 1.04 limits the Olmsted County Zoning Ordinance to unincorporated land, so this shoreland historic-site protection never reaches Rochester, Stewartville, Byron or the county's other cities, which run their own codes. The county itself only zones directly in Eyota, Marion, Oronoco and Quincy townships; the rest plan through the Township Cooperative Planning Association.
What counts as a significant historic site under this rule?
Section 9.14(F)(3) does not define the term itself; it requires that before a structure disturbs one, adequate information about the site must be removed and documented in a public repository. Property owners should confirm site status with the Zoning Administrator during the Section 9.10 permit review before building.
What happens if I build without documenting the site?
Building on a significant historic site without documenting it first is a zoning violation under Section 3.08, punishable as a misdemeanor under Section 3.10, with each day counted separately. The County Board or Zoning Administrator can order corrective measures, require an after-the-fact permit, or pursue an injunction on top of prosecution.
Is this the same as the county's floodplain and shoreland permit process?
No. The general Floodplain and Shoreland Development Permit for shoreland construction lives in Chapter 3750 of the county code, covering setbacks and flood elevations broadly. Section 9.14(F)(3) is the narrower historic-site protection layered on top of that shoreland review for parcels containing a significant historic site.
