Letter in Lieu of Improvement Plans

In certain situations, Improvement Plans may not be required. This usually occurs when the Improvement Plans have been previously approved by the health district and no changes are being made to the utilities by the current mapping process.

For example, amended maps with no new Improvement Plans being submitted, or cases where health district has approved the Improvement Plans, but more than one year has elapsed since the date of approval (and Final Map Mylar has yet to be signed by health district).

If an engineer’s letter in lieu of Improvement Plans is to be submitted, the following guidelines must be followed:

• The letter must be original and on company letterhead
• Owner/Developer must be copied
• Must be signed and wet stamped by the P.E.
• Must include one of the following paragraphs exactly as follows:

For Amended Maps:

“The initial improvement plans (water, sewer, storm drain) for [project name] that were previously approved by the Southern Nevada Health District have not been affected nor revised by this Amended Map.”

OR

For Improvement Plans approved over one year ago:

“The initial improvement plans (water, sewer, storm drain) for [project name] that were previously approved by the Southern Nevada Health District on [date of approval] have not been affected nor revised since the date of approval.”
