To minimize issues, after the last usage event of the day, it is MANDATORY to follow these best practices at ALL fields:

Best Practices Following Field Use (Game or Practice)

• Spot rake and smooth out the infield dirt all high-use / high-traffic areas:
• Batters boxes
• Catcher / Umpire area
• Pitching circle
• Running/sliding pits leading to and departing from all bases
• Spot rake and smooth out any areas where players may have played with dirt (writing words/symbols with feet, gathering dirt into mounds, etc.)
• Spot rake and smooth out any areas where buckets, nets, other equipment left indentations in the infield dirt.
• Following the last game of the day, rake out all chalk lines (batters boxes, baselines, pitching circle), as rain combining with lime causes it to cake and clump.
• Clean out dugouts
• Close and LOCK field boxes
• Turn off field lights, if necessary

Best Practices for Field Lining

• Leave a gap of about 6-12" between the outfield grass and the end of the 1st and 3rd base foul lines. Getting lime into the grass makes cleanup/removal of that lime extremely difficult. This is especially problematic if the foul line is not perfectly aligned with home plate and the outfield field pole at HS / park fields. [On a personal note, I always found it easier to line foul lines by starting near the OF, then lining toward home plate, rather than starting at home plate.]
• Avoid all other instances of dropping/spilling lime into grassy areas. For example, do not fill the liner in the grass. Do that outside the field.
• The use of string to create straight foul lines is encouraged, however, if you have to line without aids, consider standing up a bat as the end-point target location of the line.
• Pitching circles are 8' in radius from the pitching rubber, and will be in different places for 18u, 12u, and 10/8/6u. Rake out and re-draw the pitching circle as necessary if a field is shared by different age groups back-to-back.

General Raking Best Practices

• The goal of raking is to create a smooth, even surface to minimize water collection on the infield.
• IMPORTANT: Always rake in parallel to grass borders. Pushing dirt toward a grass border (e.g. the outfield) can create a dangerous lip which can cause sharp ground balls to shoot up into an outfielder's face (see Wakefield Park #8). Also rake in parallel at the grass/dirt border near the foul lines.
• Think golf bunkers and not gardening - raking should only affect the very top surface of the infield. Do not "till the soil". The only thing you will find inches under the infield is more water.
• NEVER rake standing water.
• NEVER rake a ditch or path for water to drain off the field. This creates future runoff issues.
• DO NOT RAKE if you are leaving footprints deeper than 1/4" in the area being raked.
• DO NOT RAKE if the infield dirt is forming large clumps. This is a sign the infield is too wet to rake.
• To dry out an infield, the ideal raking process is to just slightly turn over the top 1/4" of dirt. Then the air and sun conditions can quickly dry out these turned over areas. In this situation it's best to rake at minimum 1-2 hours before field usage. 
• Rake baselines perpendicularly to the direction of running, being careful not to push dirt into grassy border areas along 1st and 3rd base lines.
• Rake pitching area parallel to the rubber (e.g. 1B - 3B direction, not home plate to 2B direction)
