Working with Eastside Environmental Pros has been an absolute lifesaver during the wetlands study and permitting process for my property in Blaine, WA. The permitting requirements with Whatcom County can be incredibly frustrating, and the entire process ended up taking multiple years—but Eastside Environmental Pros stuck with me every step of the way and continued to be a steady, reliable source of support. They not only completed a thorough review and write-up of my environmental studies, but they also took the time to communicate clearly, answer every question, and tailor the report to meet the needs of both the county and myself. Their attention to detail and willingness to explain each step truly set them apart. On multiple occasions, Ashley Moyer and Kellen guided me through what to expect and helped clarify the often-scary process of dealing with wetlands on my property. One standout moment was when Kellen led a meeting with Whatcom County, cutting through the red tape and helping push through a permitting stalemate that had been holding everything up. I couldn’t have asked for a better team to work with. They were timely, realistic, supportive, and consistently advocated on my behalf. I highly recommend Eastside Environmental Pros to anyone needing environmental studies or help navigating permitting—they are exceptional.

Excellent communication which is a rare trait and much appreciated! If you are in need of their services I highly recommend contacting them and discussing your project!

We needed support for a permit, and the team at Eastside Environmental Pros was truly on our side. They helped us think through the challenge, prepared a thorough report, provided a sign-off letter, and made the permitting process far less stressful.

Eastside Environmental Pros did a critical areas report for us on our undeveloped forest land. The process was exceptionally smooth, professional in all dealings, and the final report was of an extremely high quality. We used this report to facilitate both the creation of a forestry management plan as well as the county permitting process. I highly recommend them for ecological work here in western WA.

Kellen Maloney arrived at my home as scheduled, was very easy to work with and professional. I walked the property with him and he thoroughly eplained everything he was doing. He submitted his report to me in about one week as he promised. the report will be used to help me with the King County Permitting process.

Kellen and Rebecca were a pleasure to work with! Very responsive and knowledgeable. They assisted me from the beginning of the construction process while I was looking for lots by compiling a detailed wetland report that allowed me to make an informed decision on whether to proceed with the purchase. On top of that, with their knowledge of the local building guidelines they were able to double the buildable area on my lot! Additionally, when I received a request from the building department to provide additional documentation, Rebecca assisted with the required forms at no additional cost. Can't say enough good things about Eastside Environmental Pros!

Kellen and his team are wonderful. It was a pleasure working with them. We had so much to learn, we were expertly guided through decision making every step of the way. This allowed us to make informed decisions for our project, and to honor our personal values. The team responded quickly to our many questions, and completed the documentation in a timely fashion.

We worked with Eastside on a small engagement. They are super professional and always gave the right advice w/o even worrying about their revenue. Eastside looked at our parcel and previous wetland report and gave us good pointers to move ahead with permitting process. They didn’t charge us a dime and supported the thoroughness of previous report. We would definitely use them for our future projects.

P\Reasonably priced and professional across the board; from our initial call, subsequent emails and site visit. I sought out a few quotes for residential permitting (a home addition), and Eastside Environmental Pros really stood out in listening to my needs/concerns and offering realistic and reasonable expectations.

Kellen at Eastside Environmental Pros is a GREAT person to work with. Responsive, knowledgeable, timely, and an active listener. We're building a tiny cabin on a tiny lot in a tough location, and he is paying attention to all of the unique and challenging details.

I had a very good experience with them. I engaged them to reevaluate wetland buffers for my parcel as previous evaluation came in at 225ft buffer. Kellen from Eastside did a new study and came in at 110ft buffer which opened up a lot of buildable space on my land. Their study also got credibility with king county when they approved the new buffer. I am glad that I engaged them and truly recommend their expertise in doing wetland studies.

Kellen and his team went above and beyond for us. They came out to the sight within two days of contacting them. They also corresponded with the city to verify a few key details that saved us potential time and headaches down the road. Definitely recommend their services!

Eastside Environmental is great to work with and I'm definitely looking to do business again in the future. Kellen is great to work with and his co-workers/assistances are very professional as well. Very honest and follows up on services performed. As a homeowner it can hard trying to decide which company to conduct business with in this type of field. As some won't return calls or perform subpar services. I didn't get that from Eastside, instead I received nothing but outstanding service from Eastside. And also no inflated prices after the services were performed. At this present day in time it seems challenging to find honest services and I feel that Eastside delivers highly in that area. Keep up the great work Eastside. Federal Way, WA . Anthony

Top notch experience from start to finish with Kellen and his team over at Eastside Environmental. I recently purchased a piece of land with the intent of building an Airbnb Container home; the land had a small portion of wetlands on site and after searching around for firms to perform a critical area study. After searching around online I found EE and saw that they had incredible reviews and decided to proceed. Kellen not only got me the final report within 3 weeks of initial contact but kept me in the loop throughout the whole process. I cannot wait to work with Kellen again on the next site! Cannot recommend enough.

Kellen and the team at Eastside Environmental Pros are far above the rest. In the overwhelming process of purchasing land there are many questions, especially in this area. The property we are purchasing particularly had some big question marks for us regarding wetlands and streams and we knew before making a final decision we would need professional help. We also knew that beyond the purchase we would still require professional help to properly prepare the land for building and landscaping. We called several places where we simply got the voicemail of “some guy” or other places were simply far too busy to give us the time of day. We called Kellen who answered right away and assured us that his team understood the time sensitive nature/ process of making an offer on land and the feasibility phase of the purchase. He informed us that they setup their scheduling in a way that enables them to prioritize reconnaissance studies just for this reason and got us onto the schedule right away. Not only was the customer service provided top notch from the get go but Kellen really listened to our questions and ideas and carefully addressed all of them in a timely manner. This team demonstrates true partnership and we feel confident in moving forward because we have found a reliable business that can help us a long the way. Professionalism is very important and based on the experience we had in looking for a company to work with, I can say with certainty that this business operates with excellence and professionalism which is critical when taking on such a large and potentially risky project. Thanks for “having our back” Eastside Environmental Pros!!

Eastside Environmental Pros is great. Kellen at Eastside Environmental Pros walked me through the process of critical area surveying and explained me the scope of the work in a clear manner. They were responsive through all the steps and delivered what they promised. If you are looking for a professional service with a great value, look no further.

Hello Kellen, I wanted to share my gratitude for a job well done in helping me get started on the process to be able to meet Snohomish County’s requirements so that I can develop more of my property. I was overwhelmed by what they were asking for and you really took the pressure off of me in handling the critical area review and researching all of my setbacks and requirements with the county. Now I know what I need to do to move forward with my septic contractor and with the county. You were professional, responsive and accurate with your estimate of costs. I will be sure to recommend you and your company to my family, friends and church community. Thank you again- T. Andreica Snohomish, WA

Eastside Environmental Pros are exactly as the name suggests: professionals. Amazing work (and I mean amazing), up front about everything (costs, timelines, etc), and an absolute joy to work with. This is my first time needing such a service, but the quality of the work isn't lost on me. Plus, all of the contractors and other people I've needed to pass the work onto have made comments like "this is great, who did you get to do this? I'm using them next time I need an environmental study I'm using them" Also, not only is the work amazing, but customer service is clearly a priority. I can't recommend working with them more. Seriously look no further.

I am trying to think of the right words, or where to even start in this review, as my partner and I were absolutely blown away by how amazing Eastside Environmental Pros were in completing our required Wetland Study for our new home build. Previously, my partner and I purchased a lot in Seattle to build a single family home on, and after submitting for permits, we received an alert from KC that there was a stream near our home and that a Critical Areas Report needed to be completed in order to move forward with our permits. After searching all over in Seattle for an available Wetland surveyor, we contacted over 11 different ones, only 5 returned my calls, and the 4 out of those 5 said they wouldn't have our survey completed until 4 - 6 weeks, which we could not wait any longer. But, thank goodness Kellen from Eastside Environmental connected with me and presented a great offer, and said he would have it done within 10 working days, which was way better than everyone else I spoke too. After agreeing to go with Kellen, we were absolutely blown away as he actually completed our Wetland Study earlier than expected, and kept us updated every step of the way. I usually don't write a lot of reviews, but really felt the need to showcase our amazing experience with Kellen from Eastside Environmental Pros, Inc. As he was truly a pleasure to work with, and provided one of the best customer experiences we have had throughout our construction process.
