The Founders

Trimble Surveyors was established by twin brothers David and Philip Trimble. After graduation from Penn State University and working for Huth Engineers, the brothers began the business in 1976. Working out of their garage on West Woods Drive, the Trimbles established a strong reputation for precise work throughout the Susquehanna Valley. In 1995, the firm was moved to North Lane, Lititz into the historic “Ice House”. The Ice House was the firm’s home for 21 years before the company downsized and returned to West Woods Drive. In 2013, former Trimble employee, Jeff Bowlby was hired as a partner in the firm. David and Philip retired in 2015, and Jeff Bowlby has taken over as President of the company.


The President

Jeff Bowlby was raised in Lititz and graduated from Warwick High School in 1997. After graduation from James Madison University with a Bachelor of Science in Mathematics in 2001, Jeff began his surveying career at Trimble. In 2004, Jeff was hired at Diehm & Sons, Inc. and worked as a surveyor and project manager for nine years. He is grateful to his mentors, Tim Diehm, P.L.S., Mike Kotay, P.L.S. and Jim Ober who took a rookie and turned him into a professional. While obtaining his S.I.T. and P.L.S. credentials through the state of Pennsylvania, Jeff became a partner at Trimble Surveyors in 2013 and took over leadership in 2015. The current Trimble Surveyors office is located at 307 East Lexington Road, Lititz, PA.

How much does a survey cost?


Each individual property has many factors that we take into account. The first piece of information is the property address. Using the address, we check the deed of record for the property. This allows us to see important information such as: subdivision plans, metes and bounds, deed calls, exceptions and acreage. Looking at a property deed allows us to better estimate the complexity of the possible survey. A typical fee for finding all property corners ranges between $300 - $1,000. We can provide a more accurate proposal with the above information.

What does a survey entail?

A survey entails the following:

- Online deed research at the Lancaster County Recorder of Deeds

- Field search for property evidence on your property along with your adjoining neighbors’ properties (this allows us to verify that the property corners are true and correct)

- Field survey to locate all boundary evidence found

-  Analysis of deed, subdivision plans and survey plans with current survey locations (This information can sometimes be completed in the field, other times it we bring it back to the office to better analyze the boundary solutions)

- Set 24” rebars with a yellow (“Trimble Surveyors 717-626-0028”) cap on top of property corner in grass, mag nails in macadam, concrete monuments or drill holes in curb. Most property corners are marked with a three foot wooden lath beside them The lath can be removed after property owners and adjacent owners are aware of the corner location.

How long does a survey take?


We typically can finish a survey within one to three weeks after given authorization to proceed by the client. We try to accommodate if immediate scheduling is needed.

How do I pay?


We typically send invoices at the end of each month. Our preference is a PDF invoice emailed out to you with the understanding of payment within 30 days of receiving the invoice. We do not accept credit card and prefer check payment.


Does anyone need to be home?


No, all our work is around the property and we will not need any access to anything in your home. When our work is completed, we will happily schedule a time in the evening or weekends to review our survey with you at your property if you would have any questions.


How do I preserve my survey?


There are multiple ways to document the survey:
- Letter of Survey Certification – Ask for a letter and we will write a letter stating the property was surveyed by Trimble Surveyors showing a surveyor’s signature and seal.

- Plot Plan – simple drawing showing details of the survey and property.

- Legal Description – allows the newly defined property to be recorded as the deed for the property.
