Objective zPrepare maps needed for CNMP y Location map (optional) y Soils map (optional) y Farm map (required) y Topo w/ reference to nearest town (required for permit only)

Objective z This can be a difficult task, know who will and can assist: y NRCS y Consultant y County Extension agent z Learn necessary information to provide planner or map maker

Location Map z Computer road maps z Photocopy road map z Add arrow and dot to mark farm location z Add North arrow z Add title - Location Map at bottom z Scale

Soils Map Joe Blow Farm N Soils Map - Joe Blow Farm 1 inch =900 ft

Farm Map zInformation required y Farm property lines y Land use - cropland, pasture, etc y Field boundaries y Unique field identifiers y Surface water features y Arrows showing water flow direction y Buffers or setbacks

Farm Map zInformation required (cont.) y Well locations y Residences or public gathering places* y Road names* y North arrow y Date prepared y Legend y Bar scale * Probably off of farm property

Information Sources z FSA maps z Aerial photos z Internet free - fee based - free (rudimentary) – free, requires practice z NRCS Toolkit z Other Software

NRCS Toolkit Map

Creating a Handmade Map z Obtain aerial photo, or other base map z Put a 1-inch bar scale on map before photocopy

Creating a Handmade Map

Calculating Spreadable Acreage z Mark buffers on map z Use dot grid, planimeter, etc to measure z Subtract from total acres in field *Benefit of NRCS Toolkit and other advanced software – will calculate acreages

Spreadable Acres zSurface flow directions zConcentrated flow areas zFilter strips zFrequently flooded soils zRiparian forested buffers z Setbacks ÛProperty line ÛHouses or public areas ÛWell ÛRoad z Irrigation patterns

Introduction to Buffers and Setbacks for Manure App. z Required (GA) y 35 ft vegetated or 100 ft from surface water, wet areas and ditches y100 ft from wells - separate from AFO rules z Recommended y 25 ft from property lines y 50 ft from public road (situational) y See Farm*A*Syst Improving Drinking Water for the Rural Resident for additional well setback recommendations.

Summary z Farm map is required z Has to be scaled to calculate spreadable acres z NRCS Toolkit provides best maps z Handmade base map from FSA or internet y preparer adds required information z Buffers, setbacks, and application method affect spreadable acres
