GREELEY CO Project Narrative The proposed project is located at 16876 Longs Peak Road, Greeley, CO, Weld County. The existing property is approximately 2.8 acres, with 300 feet of frontage onto Longs Peak Road and 130 feet of frontage on Pikes Peak Drive. The existing property is comprised of a single-family residential dwelling, an existing barn structure that is approximately 2000 square feet, gravel driveway, and yard / pasture (see attached map). The proposed Business Name is High Plains K-9 Connections. A Site -Specific Development Plan and Use by Special Review Permit for a kennel (up to 20 dogs four (4) months of age or older to include a dog training facility with allowance for 2 classes each evening Monday through Thursday and Saturday for obedience classes for up to ten (10) dogs and their respective owners per class. A full-time kenneling option for Clients for up to twenty (20) dogs to board their dog in order to receive one-on-one obedience training 7 -days) inside of subdivisions in the A (Agricultural) Zone District. It is proposed at this time to apply for a USR for the property in order to add an additional use: dog training / boarding. Ms. Schriefer is a certified dog trainer and intends to carry out dog training classes on the property. The classes will be held outside in the evenings during the warmer seasons. One class will run at a time for approximately one hour, with a maximum group size of ten (10) dogs per class. A full time kenneling option for Clients for up to twenty (20) dogs to board in order to receive one-on-one obedience training 7 -days per week. The future vision for the property will be to add a new structure of approximately 3500 SF. This structure will be the business portion of the property, and would include an indoor, open area for indoor dog training classes, an office area, a restroom, and a small area for kennels where clients could have their dogs boarded. This business is not intended to be a kennel for long-term stays such as when pet owners leave for holidays. The intention of the kenneling is for clients to leave their dog with Ms. Schriefer so that she can work one-on-one for more than an hour class and train the dog while he/she is under her care. As such, there wouldn't be more than twenty (20) kennels proposed for the property. An added benefit of the future facility would be that the training space would be indoors. This would allow year-round operations as well as limit the noise concerns for surrounding neighbors. The current property has an entrance / exit as with a large area available for parking. There is also a second gated access on the west side of the property that can be opened as an emergency exit. The current configuration for parking allows for approximately 15 vehicles, which is adequate for the proposed use where classes are limited to 10 dogs. For the future indoor training facility structure, a gravel parking area is proposed with fifteen (15) parking spaces (18'x9') including one (1) ADA accessible space. The parking area and laneway access will be illuminated with decorative lamps (pole -mounted). The proposed indoor training structure will have wall -mounted lighting on the east and west sides. The pole and wall -pack luminaires will be LED, downcast with low BUG rating (low Kelvin, no glare). The lighting will be pedestrian - scale for safety and to minimize impact to adjacent properties. The character of the property will improve with the Schriefer Family's vision and has already improved since their purchase of the land in April 2021. They intend to remain living in the home and envision an aesthetically pleasing barn for the future indoor dog training facility architectural style. High Plains K-9 Connection will be a family -run local business to help pet owners train their dogs to be better companions. Kimley»>Horn USR TO ADD ADDITIONAL USE: DOG TRAINING/BOARDING 16876 LONGS PEAK RD. GREELEY CO Project Support An informal neighborhood meeting was held August 6, 2021 at 6:00pm at the Schriefer Property. The meeting had a successful turnout, and the sign -in sheet from the meeting has been included in this application. Representatives from Kimley-Horn attended the meeting, and many questions from adjacent property owners were answered. Common questions received were: 1) How many dogs are proposed to be approved for the business? The applicant is proposing to have classes held weekday evenings with 10 dogs maximum at each class. It is proposed to allow up to 20 dogs for kenneling at a time. 2) Will this USR affect the zoning of adjacent properties? No, this USR will only apply to the applicant's property. 3) How long will it take for the USR to be approved? Generally, USR approval takes 6-8 months. The proposed USR has received support from multiple neighbors of the Schriefer property as well as many prospective Clients. Support letters have been incorporated to this application. Finally, the proposed USR is supported by the Weld County Charter and County Code. The site is in the Agricultural Zone District which includes uses by right for animal boarding and training facilities. The proposed meets the intent of the Agricultural Zone District and will promote the growth of a local small business, which also meets the economic development goals and objectives of the County. Supplemental Information for Kennels A. Waste Disposal The Owner will dispose of all canine waste in a trash bag within a closed garbage can every day. The garbage is collected on a weekly basis by Bunting Garbage Disposal. B. Cleaning and Sanitation for Rodent and Insect Control The Owner will use Spartan Chemical Consume Eco-Lyzer Disinfectant/Deodorant to sanitize and disinfect all dog surfaces including yards. All dog food and treats will be kept in sealable hard plastic containers to prevent any rodent or insect problems. All water bowls and food dishes will be sanitized daily. C. Drainage Facilities / Improvements to Protect Adjacent Channels Please refer to Drainage Narrative included in this application. Kim ey>>>Horn Page 2 PROPOSED USR: ADDITIONAL USE TO PROPERTY DOG TRAINING/BOARDING 16876 LONGS PEAK RD. GREELEY CO 1. Explain the Proposed Use and Business Name. The proposed Business Name is High Plains K-9 Connections. A Site -Specific Development Plan and Use by Special Review Permit for a kennel (up to 20 dogs four (4) months of age or older to include a dog training facility with allowance for 2 classes each evening Monday through Thursday and Saturday for obedience classes for up to ten (10) dogs and their respective owners per class. A full-time kenneling option for Clients for up to twenty (20) dogs to board their dog in order to receive one-on-one obedience training 7 -days) inside of subdivisions in the A (Agricultural) Zone District. The Owner / Applicant is a certified dog trainer who seeks to permit a dog training facility at the family residence located on a 2.75 -acre parcel within a platted subdivision. The proposed business will host dog obedience classes (weekday evenings), with classes held for one hour and including up to ten (10) dogs per class and their respective owners who are active participants in the class. The proposed business will also have a kenneling option for Clients to board their dog with High Plains K-9 Connections in order to receive one-on-one obedience training while being boarded. The purpose of the boarding will be training focused (i.e. the business is not proposed to be a vacation boarding facility for Owners to use while on their holidays). The future vision for the business is to develop a new structure on the property that would include a large open area inside the building to allow the classes to be held indoors. The building would also include an office, a restroom, and a separate kennel area for the boarding Clients, with a plan to eventually be able to board up to fifteen (20) dogs. 2. Explain the Need for the Proposed Use. New dog / puppy owners often need guidance on the best way to train their dogs to be good companions. This is especially true for rescued dogs who had poor experiences with previous owners. High Plains K-9 Connections intends to be a family -run, local business to serve residents in Greeley and surrounding Cities with a variety of class options to help them develop their dog's listening and obedience skills and house manners. All dogs in High Plains K-9 Connections' care will be worked with and supervised at all times. The goal of the business is a family training facility to train family orientated and well-mannered dogs. 3. Describe the Current and Previous Use of the Land. The current and previous use of the land is single family detached residential. There are pasture fields at the rear and eastern portions of the property. 4. Describe the proximity of the proposed use to residences. The proposed use is approximately 200' to the adjacent residences. 5. Describe the surrounding land uses of the site and hoe the proposed use is compatible with them. The surrounding land uses of the site include rural residential properties and agricultural fields. The proposed use of the site will be to maintain the current residential use and add the additional use of Canine Training and Kenneling. This use is common in agricultural and rural areas. It will be a benefit to the community to have a local, family -run dog training business offered in Greeley. The property has ample space for the business in addition to the existing residential use. The family running the Kim ey>>> Horn Page 3 business will remain living on the property, as it is their home. 6. Describe the hours and days of operation. Monday —Thursday: Group Dog Training Classes will be held in the evenings to accommodate the daily work schedules of most clients. Classes will be from 5:00-8:30pm. There will be no more than 2 classes per night, 4 nights a week. Maximum of two (2) classes may be held on Saturdays. For Clients requesting Boarding & Training, the business will request all dogs be dropped off in the morning (8-11 am) and picked up in the evening (2-5pm) Monday — Friday. Drop off and pick up times are reserved with the owner in advance. Weekends will be by appointment only. The business will not have more than 1-2 clients on the property for arrival or drop off at a time. 7. Describe the number of employees including full-time, part-time, and contractors. If shift work is proposed, detail number of employees, schedule and duration of shifts. No shift work is proposed. The business may need to hire one additional person in the future (part- time with potential to be full-time depending on business demand). The current staff are John and Megan Schriefer (i.e. business owners and property owners). 8. Describe the maximum number of users, patrons, members, buyers or other visitors that the site will accommodate at any one time. The maximum number of patrons at any one time will be for the Group Dog Training Classes, which will be maximized at ten (10) people per class. 9. List the types and maximum number of animals to be on the site at any one time. The maximum number of animals to be on site at any one time would be ten (10) dogs for the Group Dog Training Class plus twenty (20) dogs in the kennel program being boarded for Boarding & Training (i.e. 30 dogs total). The training for the dogs being kenneled as Boarding & Training clients would take place separately from and at different times than the Group Training Classes. 10. List the types and number of operating and processing equipment. No operating or processing equipment is anticipated to be required for this business. 11. List the types, number, and uses of the existing and proposed structures. The existing structures include the residential dwelling and the detached garage / barn (2000 SF). There is one (1) proposed structure: a 3500 SF building which will be used for indoor dog training, kenneling, and will have an office space and restroom. 12. Describe the size of any stockpile, storage, or waste areas. A small (3'x3') trash location is proposed on the southeast corner of the existing garage / barn structure. Kimley»>Horn Page 4 13. Describe the method and time schedule of removal or disposal of junk, debris, and other wastes associated with the proposed use. The business disposes of all canine waste in a trash bag in the garage every day. The business uses Bunting Garbage Disposal, which is collected on a weekly basis. 14. Include a timetable showing the periods of time required for the construction of the operation. At this time no construction is proposed. It is intended in the future (approximately 1-2 years after USR approval) to build the proposed 3500 SF indoor training facility. It is anticipated that the construction of this structure and associated parking area would be approximately 2-3 months after all approvals were in place. 15. Describe the proposed and existing lot surface type and square footage of each type (i.e. asphalt, gravel, landscaping, dirt, grass, buildings). The existing property is comprised of one (1) single residential dwelling, one (1) detached garage, driveway, and agricultural pasture lands. The existing entrance around the residence is gravel laneway, approximately 200' long and 19' wide. A 65' x 75' gravel parking area would be proposed in the future to support the future indoor training facility building (approx. 3500 SF). The parking area would be accessed by a proposed 17.8' wide x 200' long laneway from the entrance to the site. See attached map for reference. 16. How many parking spaces are proposed? How many accessible parking spaces are proposed? Fifteen (15) 9'x18' parking stalls are proposed with one (1) being ADA van accessible. 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. The existing fencing includes split rail and steel rail fence. It is proposed to have privacy fencing for the site around the proposed dog training area (see map). 18. Describe the existing and proposed landscaping for the site. The existing landscaping includes mature trees and shrubbery. The majority of the existing landscaping will be maintained. 19. Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity. Kimley>»Horn Page 5 Minor restoration of the landscaping and driveway may be required after construction has completed. The contractor that is hired to construct the future indoor facility and parking area will be required to include restoration costs in their contract bid. 20. Describe the proposed fire protection measures. There is an existing fire hydrant at the northwest corner of the property. The laneway to the parking area will be wide enough for a fire truck to maneuver. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. Sec 22-2-10 — Guiding Principles: Respecting Agricultural Heritage; Promoting Economic Growth and Stability: • The existing property is within the Agricultural Zone District. Canine training and boarding is a common use within Agricultural Zones and will be well -suited for this large property. There is plenty of pasture space, plenty of room for buffering from the adjacent properties, and will not detract from the existing character of the neighborhood. • The code promotes Economic Growth and Stability. This proposed business will be a family - owned and operated business. The business will allow the family to maintain their home in Greeley and will provide for their stability. Local businesses are essential to the growth and prosperity of communities and this will be a great addition to the local businesses in Greeley. Section 22-2-40 — Economic Development Goals and Objectives Promote small business incentive programs to encourage small business owners. The approval of this USR would encourage the small business owners of High Plains K-9 Connections to grow their business and operate under proper authorization. 22. Explain how this proposal is consistent with the intent of the zone district in which it is located. (Intent statements can be found at the beginning of each zone district section in Article III of Chapter 23 of the Weld County Code.) Section 23-3-10 — Intent The Agricultural Zone District is established to maintain and promote agriculture as an essential feature of the County. Section 23-3-20 outlines the Uses By Right within the agricultural zone district which includes: Animal Boarding and Animal Training Facilities where the maximum number of animal units or household pets permitted in Section 23-3-70D is not exceeded and traffic to and from the facility does not exceed 60 daily trips. Dogs are not included in the animal unit table (Table 23.1A); the total number of dogs proposed on the site include 10 dogs per class and 15 dogs to be boarded at a time. The traffic letter prepared for this file outlines the estimated trip generation as 44 daily trips. Therefore, the proposed complies with the traffic requirements of Section 23-3-20. Kimley»>Horn Page 6 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. The intent of the area is to remain as zoned (A S-52). As it is within the Agricultural Zone District, the proposed use should preserve the intent of that district; this USR is consistent with the intent of the district. 24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. The proposed USR should not negatively impact the health, safety, and welfare of inhabitants of the neighborhood / County. The approval of this USR will positively impact the welfare of the applicants, as it will allow them to own and operate their proposed business. They will maintain a healthy and safe property and business through their disposal and sanitation practices, property maintenance and upkeep, and proposed fencing around the property. 25. Describe any irrigation features. If the proposed use is to be located in the A (Agricultural) Zone District, explain your efforts to conserve prime agricultural land in the locational decision for the proposed use. The proposed USR shows that the majority of the property will be maintained as pasture fields, conserving prime agricultural land. Dog training and kenneling is an allowed use by right in the agricultural zone district, so using a portion of the property for this use will still maintain the intent of the district. 26. Explain how this proposal complies with Article V and Article XI of Chapter 23 if the proposal is located within any Overlay Zoning District (Airport, Geologic Hazard, or Historic Townsites Overlay Districts) or a Special Flood Hazard Area identified by maps officially adopted by the County. The proposal is not within any of the overlay zoning districts described above. The FEMA Firmette included with the Drainage Letter shows that the property is not identified as a Special Hazard Area. 27. Detail known State or Federal permits required for your proposed use(s) and the status of each permit. The Owner and Operator of any dog training and / or kenneling business should be a licensed dog trainer. Megan Schriefer is a certified AKC Evaluator and has been since 2010. She also graduated as a Professional Dog Trainer in October 2014 from the Karen Pryor Academy. Megan completed a Trick Training course and received a certification in June 2020. She is certified in Canine CPR and is a member is good standing with the Association of Professional Dog Trainers. Provide a copy of any application or permit.

CO 80525 Kimley»>Horn WASTE MANAGEMENT PLAN PROPOSED USR: ADDITIONAL USE TO PROPERTY DOG TRAINING/BOARDING 16876 LONGS PEAK RD. GREELEY CO High Plains K-9 Connections will be implementing a Waste Handling Plan for our proposed dog kenneling and training business. Wastes will be generated by the dogs on -site and will be stored in sealed bags within an enclosed standard large garbage can (96 gallon) located adjacent to the kenneling building. The new kenneling building will not be installed with the initial operations; however, the standard large garbage can will be located in the area where the proposed new building will be constructed in the future. The expected volume of waste generated will be limited to dog waste and miscellaneous refuse from the visitors on -site for the training classes as well as employees of the business (i.e. lunch containers, beverage containers, etc.). The current employees of the business are also the residents of the house. The volume will be collected in the 96 gallon Polyethylene Outdoor Garbage Can and collected weekly by the waste handler (Bunting Garbage Disposal). The waste handler and facility where waste will be disposed is as follows: Waste Handler: Bunting Disposal, Inc.

Learn why this is important August 9, 2021 Dear Caitlin, Our names are Dale and Sherrie Jay and we are neighbors to the Schriefers in Pinnacle Park. We are in full support of Megan running her dog training business from their home. This is a young, hard-working couple who are just trying to make a living like everyone else. They have made tremendous improvements to their property that also benefits the entire neighborhood. I have seen no increase in traffic and we live right at the entrance. I might add that we have lived here for 35 years so we would know if there was a difference. I see absolutely no reason why she shouldn't be able to run her business from her home as they have proven themselves to be kind, conscientious neighbors. And, given their ages, I am more than impressed with how they have presented themselves. Feel free to contact us if you have any questions.

Learn why this is important To Whom it May Concern, This letter is being written in support of Megan and John Schriefer and their business, High Plains K9. We were surprised to hear that anyone in the neighborhood had concerns that led to letter of complaint when they first moved in. They have made huge improvements to the property, fencing, and driveways to be used for the facility and their future plans are well thought out and respectful to all of their neighbors. We have no concerns about traffic, dog noise, or future expansion plans. Our hope is that our neighbors would engage in a conversation with Megan and John who are a wonderful couple who desire nothing more than to run their business AND maintain good relationships with the neighbors. We look forward to watching High Plains K9 open and bring new life into our community!

Since they have moved in, their property has only seen continued and noticeable improvements and enhancements, which has only added to our efforts to keep our neighborhood looking good. They are very mindful of our tiny community and any action they take in pursuit of their dream. They have gained respect and friendships from neighbors throughout our community. We have had no concerns whatsoever in them planning their business to be conducted from their private property. We see no concerns in the future and have asked questions whenever we were curious as to how they would handle various issues that may arise, including any additional traffic that may occur. We are confident changes made to the property, be it for personal or business reasons, will only add to our neighborhood and we welcome this motivated couple without hesitation to Pinnacle Park. Feel free to reach out directly if you have any additional questions. We wish the Schriefer family the best of luck in successfully settling this in a positive manner that allows them to continue their dream and being our neighbors.

I Icr ample experience in her field has personally helped both my clog, Beau, and 1. Megan came highly recommended to me from a coworker when I was inquiring about the necessary obedience training to make my golden retriever a therapy dog. I reached out to Megan in regards to whether therapy would be a good fit fur my dog and it all went uphill from there. We participated in her Canine Good Citizen (CGC) class, as well as her CGC Community Class. Both classes were handled professionally, ran with structure, and were obviously well planned prior. High Plains K-9 Connections helped Beau and I not only prepare for the AKC tests we had to take at the end of our class' duration, but it also prepared us perfectly for our therapy (log exam. Beau is now a registered therapy dog, with a "job" at a UcHcalth hospital. In our therapy team evaluation, the evaluator made a point to mention that most brand new teams rarely do well enough to score a "complex" rating. This is the highest rating, which allows us to be able to visit any environment and Beau and I received the complex rating. I would not have been able to get there without all of Megan's hard work. She truly helped me reach my personal goal with Beau in every way she could. I can confirm that Megan is extremely dedicated to High Plains K-9 Connections and each individual teams that comes to her, She is an incredible problem -solver, thinks on her Feet, is honest, reliable and is flexible to as many individuals' schedules as she can bc.Without a doubt, Megan deserves the rezoning permit to be able to expand and run I liglt l'Iains K-9 Connections.

We took our 4 -month -old puppy to them for basic training and socialization. Megan Schriefer did an amazing job with helping our puppy have basic manners and caught some bad behaviors developing that we did not notice. We now have a wonderful, well-behaved one -year -old that Is on her way to becoming a therapy dog. After having a great experience with our puppy, we decided to do their AKC Good Citizen Certification class with our puppy and 4 -year -old dog. It was a challenge to have two dogs in one class, even with two handlers, because our dogs look to me for guidance. However, Megan was understanding and made it easy to train both dogs in one class. She even accommodated our need for additional training while around other dogs, as well as my need to handle both dogs during the examination. We have since participated in at least one of their classes every session. We plan to continue to work with them with our current dogs and future dogs. I have recommended them to friends, family, and strangers that see how well behaved my dogs are in public settings. We have gone to multiple trainers over the years. However, after our class was done, we have moved on to a new trainer. We could not find one that worked well with our dogs; they were either too lenient, too rigid, or just poor trainers. High Plains K-9 Connections has been the perfect fit. They tailor training to the dog and come up with ways to help each type of situation, as well as catching early negative behavior signs before they become a problem. Because of them, we are working towards therapy certification with two of our dogs. Once complete we will volunteer at schools, hospitals, and other places that need therapy dog services. Through their dedicated work with our community's four -legged family members, High Plains K-9 Connections has, and continues to, positively impacting the community. There would be a huge loss of quality dog training in Northern Colorado without them. Sincerely, Amber Sampson — August 2"d, 2021 August 2, 2021 To Whom it May Concern: This letter is in reference to Megan Schriefer, owner of High Plains K-9 Connections, who is requesting rezoning of her Greeley property to allow for enhancements to her business. I have known Megan for almost three years, in which time my dog and I have completed four of her AKC training classes. Megan is an exceptional teacher and dog trainer, who makes class time very productive, but also fun. My dog gets frequent compliments from family, friends and strangers on his excellent obedience and good behavior. i have also used Megan's daycare and boarding services on a regular basis. It is a great comfort to leave my dog with Megan because she goes out of her way to make my dog feel like part of the family and give him the attention he needs while I'm away. I completely endorse Megan's business plans for her new location, where she can provide expanded training opportunities and continue to provide excellent daycare and boarding for her clients. Megan Is a great asset to the community.

She has been a blessing to us with the care and love she gives to our two boys, Trex and Drake over the years (Trex (8 yrs old) Is a rescue black lab mix and Drake (3 yrs old) is a white lab). Our boys both have gone through training with Megan and Drake even stayed with her for a couple weeks to help him get over his timidness around children and being a well-behaved pup in our home. We depend on Megan a lot when we travel as she is the only one we trust to take our boys. I cannot tell you how much it means to us to have someone like her to care for our boys like she does. We could not have children, so they really are our babies and to know we are leaving them with her Is truly a relief on me and my husband. *Any time someone is looking for a reference for dog training or boarding/day care, I immediately give them Megan's information. I pray that her business can grown so others can feel such comfort like we do.

We have known and worked with Megan for the last 2 years. Megan was recommended to us by Progressive Dog School when my Corgi was a baby. We had not had a dog before and wanted to ensure we began his training off correctly. Megan came to our house for a 15' lesson and gave us homework. When her puppy classes began, we immediately signed up. We have taken several of her classes and were amazed how she taught to the differences in each dog in our class. Megan quickly learned each dog's personality and taught from their strengths. Megan is a great trainer of dogs and teacher for their parentsl High Plains K-9 Connections is also where we take our dog for boarding. My dog loves to go there, even jumping out of the car before we can grab him. He never looks back at his parents, just the adventure ahead. As new dog parents, we have never had any concerns about his care or safety. Megan is careful to put dogs together who will play well together, and fully monitors them In the yard. When on a trip, we get periodic updates by text, pictures of him playing and even have received a paw print picture to celebrate an upcoming holiday. We would encourage you to quickly provide the Schriefers and High Plains K-9 Connections with the appropriate permits to continue their service to dogs and their parents. High Plains K-9 Connections is a needed service, and the Schriefer Family will be great neighbors. Feel free to contact us for any additional information at 970-381-3069.

Megan has assisted our family in training our two Labrador Retrievers, and we have frequently boarded our puppy at High Plains. Lab puppies are a bit trying for the first year+ of their lives, and Megan has been instrumental in helping us train Grace to become a valued and much - loved member of our family. Our puppy Grace has taken part in High Plains' dog daycare, puppy school, Beginner Obedience Training I and II, and Canine Good Citizen, as well as participated in some additional private training. We value the High Plains' business model and appreciate the fact that High Plains is a family -owned business. We hope to be able to continue our support of High Plains in the future, as we feel very comfortable leaving Grace in Megan and her family's care. Should you have additional questions, please do not hesitate to contact me. Sincerely, Kiimberly Tregoning Kimberly Tregoning :kt August 1, 2021 Weld County Planning Department 1555 N 17" Avenue Greeley, CO 80631 Rezoning Application Support Letter To Whom this Concerns, I met Megan Schriefer in September of 2020. I needed help and guidance in crate training my new puppy, so I asked my 18 year - old granddaughter who she had gone to for instruction. Her reply, almost word for word, "Nana, you gotta call Megan Schriefer. She is the best trainer I have ever been to." So, I gave Megan a call and have been with her ever since. My pup, Kirby, who is now a year old, is a happy, energetic golden doodle. Megan knows and understands how to help me train her. Megan is kind and patient. Not only that, it is apparent she truly adores her dog clients and wants the best for them. Therefore, her focus is not only on them but on their parents too, so we can also offer them our best. We just returned from Kirby's first camping trip. She did great! She appeared to love her hikes and rides on the pontoon, as well as on the kayak with the grandchildren. I wish I could show you a picture. Kirby is well adjusted and is a valued family member. Her good behavior and sweet attitude are all due to Megan's training and the socialization she receives with other dogs and people while participating in class instruction and boarding. It is evident Kirby has been loved and cared for well while she is with Megan. I would not entrust my beloved pet to her if this were not the case. I have witnessed that High Plains K-9 Connections is a family affair. Megan and her husband, John, are an adventurous, entrepreneurial young couple as they strive to make their passions and dreams become reality. Their two young sons are involved as they enjoy and play with the boarding dogs. This family is refreshing to be a part of. Why? Because it is not often that I personally run into this particular kind of hard- working spirit that this family offers. Megan is a professional in all aspects of her career. She received her education from one of the best trainers and boarding facilities in Northern Colorado, Liz Blazio, Progressive School for Dogs. Therefore, from my perspective, Megan is developing a similar reputation as to that of Liz. It is my belief that just as Progressive Schools for Dogs is a quality, beneficial asset for Greeley and our extended community, so will this be true of High Plains K-9 Connections. I am asking that you allow rezoning to occur on behalf of Megan Schriefer and her property; so that she might receive the appropriate permits and rights to run and expand High Plains K- 9 Connections. Thank you for your time. Respectfully, Patricia Weber-Malpiede 970-381-8633 August 7, 2021 To Whom it May Concern: We are writing to you, regarding Megan Schriefer, from High Plains K-9 Connections. We are currently taking our second class with our dog, Gunnar. Megan and her husband seem to be very responsible landowners... and very good neighbors to the development. From the very first class we attended, she stressed that we be respectful of the neighborhood. She made sure we did not park in other's yards. She stressed the importance of observing the speed limits posted. She keeps her dog training classes limited to help in this endeavor. We believe she will continue to do this as she and her family develops their dream. She loves what she does..... and it shows! We have been dog owners in the past, but never had a puppy before and Megan has been very helpful and instrumental in assisting us to train our dog. She gave us tips the first class we had, to teach Gunnar not to pull, when walking. Her methods of training are very positive and interactive. He works with us individually and in a group. She is very supportive and wants everyone to be successful dog trainers and owners. We will be recommending Megan as a trainer to anybody who asks! We hope you consider approving Megan Shriefer's application for land -use for the property her family has purchased. Thank you for consideration of his letter. Sincerely, Bill and Sue Sinnwell wjsinnwell@aol.com 8/5/2021 Rezoning Application Support Letter To Whom it May Concern, I am writing in support of the rezoning application for 16876 Longs Peak Rd Greeley CO 80631, High Plains K-9 Connections. They have been a helpful business to our family, allowing us to access dog training programs a short distance from our home. Dogs that are trained benefit not only the family owning them, but also neighborhoods and communities as they are less likely to cause problems, get loose or bother neighbors. Our experience with them has been very positive and I hope to continue to utilize the programs from High Plains K-9 Connections in this convenient location. Thank you for your consideration.

We decided to take training classes from Megan Schriefer at High Plains K-9 Connections. We benefitted so much in our first six -week puppy class that we signed up for her second six -week classes. Our puppy has learned so much and more importantly myself and my husband have learned how to training and interact with Maggie Mae. Her activity level was so much more than we had planned on but the training we received from Megan has made the difference for us. Maggie was getting a little too active with our 10 - year -old Bulldog and Megan has helped Maggie learn how to properly interact with an older dog. Our entire household has benefited from Megan Schriefer at High Plains K-9 Connections Recently we have taken Maggie to doggy daycare at High Plains K-9 Connections and love the activity that Maggie gets there. The kennels are clean and the play areas are safe and excellent for dog interactions. She gets play time but just as importantly kennel time to relax and unwind. Maggie loves it there. We are looking forward to having a place to kennel our dogs, if we ever need to do that, once High Plains K-9 Connections are approved to expand their kennel facility. Sincerely, Debra LeFeber Weld County Planning Department 1555 N. 17th Ave Greeley, CO 80631 Rezoning Application Support Letter Dear Planning Department, This letter is in support of the rezoning request by High Plains K-9 Connections for the property at 16876 Longs Peak Rd, Greeley Colorado. Megan Schriefer has been the trainer and kennel provider for our 2 year old dog since she was a puppy. We've had other puppies with other trainers who never came close to achieving the training, manners and loving character of our current dog. I attribute this to Megan. She trains in a gentle, loving, playful manner which always made our dog eager to spend time with her and obey her. She achieved this in a short period of time while also helping me continue her training on my own. If I had a problem or concern, Megan was always available and willing to help. Luckily our association with Megan did not end upon training. Her boarding facility became a wonderful, homelike atmosphere where we could board our dog with complete confidence. You always knew her first concern was for the dogs in her care from the cleanliness, to the safety features and the activities. It was such a welcome change from the other kennel options we had used. Our dog can hardly wait to go to the "doggy motel." Please use this letter of recommendation to support the rezoning request for High Plains K-9 Connections. The service, expertise and professionalism they provide for Greeley dog owners is so needed and unsurpassed. Thank you for your consideration.

The project site is located near the northwest comer of the State Highway 392 (SH-392) and Pikes Peak Drive intersection. The site currently consists of one (1) single family residence and the property owner is submitting for a use by right application to permit a dog training and boarding facility on the existing property. The training classes are proposed to include up to 10 dogs while the boarding kennel has a capacity of 20 dogs. A site plan is attached for reference. Background Information The owner is a certified dog trainer with plans to provide dog training services and boarding on their 2.75 -acre property. The dog boarding is not intended for daily boarding or boarding for dogs while owners go on vacation. The boarding is intended for dogs that are being trained on site for a minimum of two weeks. Dog training classes will occur in the evenings starting at 6:00 pm for a maximum of 10 dogs. These classes are scheduled for two separate sessions three evenings a week occurring Monday through Friday. The classes will be held one class at a time for one hour with the first class anticipated to occur 6:00-7:00 pm and the second class from 7:15-8:15 pm. There is an existing 2,000 square foot barn that is anticipated to be replaced with a 2,400 square foot new structure. This new structure will provide an indoor area for dog training, an office area, a restroom, and a small kennel area for dogs to be boarded for long-term dog training. With the new facility, dog training will occur indoors which allows for year-round operations and limits noise for surrounding neighbors. The owner of the property will be training dogs and additional staff will not be added to the company. Site Access and Circulation The existing residence currently has two driveways along Longs Peak Road with access to the property. The west access along Longs Peak Road is proposed for client use to gain access to 15 proposed parking spaces located in the middle of the property south of the existing house on site. It is believed that 60 percent of clients will originate from the east from Greeley and Easton and 40 percent of the clients will originate from the west from Windsor, 1-25, and those surrounding areas. It is anticipated that most vehicles will use SH-392 to access Pikes Peak Drive but there is an additional route to the site via CR-35 to Longs Peak Road. Kim ley >>> Horn Traffic Assessment Letter 196238000 Page 2 Trip Generation Site -generated traffic estimates are determined through a process known as trip generation. Rates and equations are applied to the proposed land use to estimate traffic generated by the development during a specific time interval. The acknowledged source for trip generation rates is the Trip Generation Manual' published by the Institute of Transportation Engineers (ITE). ITE has established trip rates in nationwide studies of similar land uses. Given the specific nature of this site, a methodology separate from the typical ITE Trip Generation Manual and Handbook was developed based on user specific data to determine the trip generation potential of the proposed site. The trip generation for the project was based on the size and schedule of training classes as well as dog boarding schedules and capacity. The two evening training classes of up to 10 dogs per class are expected to occur three nights per week outside of the peak hour of the adjacent street. With training classes at full capacity, a total of 20 vehicle trips in and 20 vehicle trips out of the site are expected in association with the training classes. The boarding is intended for dogs that are being trained on site for a minimum of two weeks; therefore, approximately one (1) dog would arrive and one (1) dog would depart the facility each day if training visits averaged three weeks in duration (minimum of two weeks required). This equates to four vehicle trips per day as a vehicle trip in and a vehicle trip out is two trips. However, vehicle trips would occur less frequently for dog boarding if long-term training visits extend longer than an average of three weeks. It should also be noted that dog boarding trips can also occur outside of the peak hour of the adjacent street. To provide a conservative analysis, it was assumed that dog boarding trips each day would occur during the peak hour of the adjacent street; therefore, one (1) vehicle would arrive and depart during the morning peak hour for dog boarding/training and one (1) vehicle would arrive and depart during the afternoon peak hour for dog boarding. Table 1 summarizes the estimates trip generation for the project. Table 1 — High Plains K-9 Connections Project Traffic Generation Use, _Weekday Vehicles Tilpe Daily AM Peak our PM Peak Houk 1n �it fi+ tal In . Out ''Fatal Project Traffic: User Specific Data 44 1 1 2 1 1 2 As shown in the trip generation table, the High Plains K-9 Connections project is anticipated to generate approximately 44 daily trips with two (2) trips occurring during both peak hours. A traffic impact study is typically not required for a development if daily vehicle trip -end generation is less than 100 trips per day or the peak hour trip generation is less than 25 trips. Therefore, it is anticipated that a traffic impact study will not be required for this development due to the project being a very low traffic generator. Additionally, no new major street intersections are proposed, and the project is not anticipated to adversely impact the roadway network adjacent to the property. It is believed that the project will be successfully incorporated within the existing roadway network. 1 Institute of Transportation Engineers, Trip Generation Manual, Tenth Edition, Washington DC, 2017. Adjacent Use Trip Generation Traffic Assessment Letter Kimley>>> Horn 196238000 Page 3 CDOT Access The threshold for requiring an access permit along Colorado Department of Transportation (CDOT) roadways occurs when project traffic is anticipated to increase existing access traffic volumes by more than 20 percent. Based on traffic projections, the addition of High Plains K- 9 Connections project traffic along SH-392 on the north leg at SH-392 and Pikes Peak Drive intersection is not anticipated to increase existing access traffic volumes by more than 20 percent. Of note, the trip generation (attached for reference) for the number of single-family homes (29) in the area that currently use the SH-392 and Pikes Peak Drive intersection during the peak hours was calculated to determine how much the project traffic could potentially contribute to the intersection. Project traffic at the north leg of Pikes Peak Drive at SH-392 is anticipated to increase existing traffic by eight (8) percent (2 project/25 existing) during the morning peak hour and six (6) percent (2 project/31 existing). Therefore, a CDOT access permit is not anticipated to be required at the intersection in association with this project.

This letter has been prepared to describe the drainage basin revisions associated with the proposed improvements to the Site. The High Plains K-9 Connections Improvements project consists of 2.84 acres located at 16876 Longs Peak Rd. in Weld County. The Site currently consists of a single-family residential structure, an approx. 2000 SF barn structure, gravel driveway/parking, and undeveloped grass pasture/landscape area. The proposed development add an additional approx. 3000 SF detached training structure, as well as additional gravel parking, and will maintain the existing zoning and use. The composite imperviousness of the existing Site is 10%, denoted in the attached Drainage Plan as Basin A-1. The site drains to the south and east at slopes between 1-2% and is tributary to the adjacent Greeley Number 2 Canal, denoted in the attached Drainage Plan as Design Point A- 1. This site is located on FEMA FIRM map number 08123C1530E, dated 1/20/2016, and lies within Zone X, which is defined as areas determined to be outside the 0.2% annual chance floodplain. This site is composed predominantly of NRCS Soil Type A. The composite imperviousness of the developed Site is 14% and will maintain the historic drainage patterns of the existing site. The attached calculations show minimal increases in runoff during the Minor (5 -year) and Major (100 -year) storm events, and are also summarized below: RATIONAL CALCULATIONS SUMMARY DESIGN POINT TRIBUTARY BASINS TRIB. AREA (AC) PEAK FLOWS (CFS) Q2 Q5 Q100 On -Site Basins Al Existing -Al 2.84 0.23 0.30 2.12 Al Proposed -Al 2.84 0.34 0.46 2.53 As shown in the table above, and in the attached Standard Form Calculations, the proposed development will increase the Minor (5 -year) Peak Flows by 0.16 CFS and the Major (100 -year) Peak Flows by 0.41 CFS. These flow increases are minimal, and do not merit implementation of full -spectrum detention facilities. In order to attenuate these flows, a grass buffer shall be implemented along the southern side of the property, as noted in the attached Drainage Plan. Final Drainage Compliance Letter High Plains K-9 Connections Improvements — Weld County, CO This grass buffer shall follow Mile High Flood District (MHFD) design and construction recommendations Calculations and recommendations for this buffer have been included as attachments to this letter Implementation of a grass buffer will help to attenuate the fractional increase in runoff from the site, as well as provide sufficient Water Quality treatment to this runoff As summarized above, the Applicant is requesting a detention exception per Weld County — Charter and County Code Section 8 XI I on the basis that the developed flow increases proposed are minimal, and shall be mitigated through the use of a MHFD Grass Buffer facility The historic drainage patterns will be maintained for this development — discharging to the adjacent Greely Number 2 Canal It is our determination that the development of the High Plains K-9 Connections Improvements will have minimal impacts on the existing improvements surrounding the Site, based upon the negligible increases in peak runoff resulting in the development of this project, and implementation of a Grass Buffer facility for flow attenuation and Water Quality treatment No further stormwater infrastructure improvements are proposed at this time Sincerely, KIMLEY-HORN AND ASSOCIATES, INC Kevin Johnk, P E Project Engineer Attachments — FEMA Firmette, NRCS Soil Survey, NOAA Point Rainfall Data, Standard Form Calculations (1, 2, & 3), MHFD Grass Buffer Summary & Sizing, Drainage Plan 21 Page National Flood Hazard Layer FIRMette FI'1.\ Legend 0 250 500 1,000 1.500 2,000 (. t)' V V V Basemap: USGS National Map: Orthoimagery: Data refreshed October, 2020 SEE FIS REPORT FOR DETAILED LEGEND AND INDEX MAP FOR FIRM PANEL LAYOUT Without Base Flood Elevation (BFE) Zone A, V.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. Rating Options Aggregation Method: Dominant Condition 97.4% 2.6% 100.0% USDA Natural Resources Web Soil Survey 8/5/2021 Conservation Service National Cooperative Soil Survey Page 3 of 4 Hydrologic Soil Group —Weld County, Colorado, Southern Part Aggregation is the process by which a set of component attribute values is reduced to a single value that represents the map unit as a whole. A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not. For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of 60 indicates that the corresponding component typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Dominant Condition" first groups like attribute values for the components in a map unit. For each group, percent composition is set to the sum of the percent composition of all components participating in that group. These groups now represent "conditions" rather than components. The attribute value associated with the group with the highest cumulative percent composition is returned. If more than one group shares the highest cumulative percent composition, the corresponding "tie -break" rule determines which value should be returned. The "tie -break" rule indicates whether the lower or higher group value should be returned in the case of a percent composition tie. The result returned by this aggregation method represents the dominant condition throughout the map unit only when no tie has occurred. Component Percent Cutoff., None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. Tie -break Rule: Higher The tie -break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie.

Properly designed grass buffers play a key role in LID, enabling infiltration and slowing runoff. Grass buffers provide filtration (straining) of sediment. Buffers differ from swales in that they are designed to accommodate overland sheet flow rather than concentrated or channelized flow. Site Selection Grass buffers can be incorporated into a wide range of development settings. Photograph GB -1. A flush curb allows roadway runoff to sheet flow Runoff can be directly accepted from a through the grass buffer. Flows are then further treated by the grass parking lot, roadway, or the roof of a swale. Photo courtesy of Muller Engineering. structure, provided the flow is distributed in a uniform manner over the width of the buffer. This can be achieved through the use of flush curbs, slotted curbs, or level spreaders where needed. Grass buffers are often used in conjunction with grass swales. They are well suited for use in riparian zones to assist in stabilizing channel banks adjacent to major drainageways and receiving waters. These areas can also sometimes serve multiple functions such as recreation. Hydrologic Soil Groups A and B provide the best infiltration capacity for grass buffers. For Type C and D soils, buffers still serve to provide filtration (straining) although infiltration rates are lower. Designing for Maintenance Recommended ongoing maintenance practices for all BMPs are provided in Chapter 6 of this manual. During design the following should be considered to ensure ease of maintenance over the long-term: ■ Where appropriate (where vehicle safety would not be impacted), install the top of the buffer I to 3 inches below the adjacent pavement so that growth of vegetation and accumulation of sediment at the edge of the strip does not prevent runoff from entering the buffer. Alternatively, a sloped edge can be used adjacent to vehicular traffic areas. ■ Amend soils to encourage deep roots and reduce irrigation requirements, as well as promote infiltration.

November 2010 Urban Drainage and Flood Control District GB -1 Urban Storm Drainage Criteria Manual Volume 3 T-1 Grass Buffer ■ Design and adjust the irrigation system (temporary or permanent) to provide water in amounts appropriate for the selected vegetation. Irrigation needs will change from month to month and year to year. ■ Protect the grass buffer from vehicular traffic when using this BMP adjacent to roadways. This can be done with a slotted curb (or other type of barrier) or by constructing a reinforced grass shoulder (see Fact Sheet T-10.5). Design Procedure and Criteria The following steps outline the grass buffer design procedure and criteria. Figure GB -1 is a schematic of the facility and its components: 1. Design Discharge: Use the hydrologic procedures described in the Runoff chapter of Volume 1 to determine the 2 -year peak flow rate (Q2) of the area draining to the grass buffer. 2. Minimum Width: The width (W), normal to flow of the buffer, is typically the same as the contributing basin (see Figure GB -1). An exception to this is where flows become concentrated. Concentrated flows require a level spreader to distribute flows evenly across the width of the buffer. The minimum width should be: _ Q2 Equation GB -1 W 0.05 3. Where: W = width of buffer (ft) Q2 = 2 -year peak runoff (cfs) Benefits ■ Filters (strains) sediment and trash. • Reduces directly connected impervious area. (See Chapter 3 for quantifying benefits.) ■ Can easily be incorporated into a treatment train approach. ■ Provides green space available for multiple uses including recreation and snow storage. ■ Straightforward maintenance requirements when the buffer is protected from vehicular traffic. Limitations ■ Frequently damaged by vehicles when adjacent to roadways and unprotected. ■ A thick vegetative cover is needed for grass buffers to be effective. ■ Nutrient removal in grass buffers is typically low. ■ High loadings of coarse solids, trash, and debris require pretreatment. Length: The recommended length (L), the distance along ■ Space for grass buffers may not the sheet flow direction, should be a minimum of 14 feet. be available in ultra urban areas This value is based on the findings of Barrett et al. 2004 in (lot -line -to -lot -line). Stormwater Pollutant Removal in Roadside Vegetated Strips and is appropriate for buffers with greater than 80% vegetative cover and slopes up to 10%. The study found that pollutant removal continues throughout a length of 14 feet. Beyond this length, a point of diminishing returns in pollutant reduction was found. It is important to note that shorter lengths or slightly steeper slopes will also provide some level of removal where site constraints dictate the geometry of the buffer. GB -2 Urban Drainage and Flood Control District November 2010 Urban Storm Drainage Criteria Manual Volume 3 Grass Buffer T-1 4. Buffer Slope: The design slope of a grass buffer in the direction of flow should not exceed 10%. Generally, a minimum slope of 2% or more in turf is adequate to facilitate positive drainage. For slopes less than 2%, consider including an underdrain system to mitigate nuisance drainage. 5. Flow Characteristics (sheet or concentrated): Concentrated flows can occur when the width of the watershed differs from that of the grass buffer. Additionally, when the product of the watershed flow length and the interface slope (the slope of the watershed normal to flow at the grass buffer) exceeds approximately one, flows may become concentrated. Use the following equations to determine flow characteristics: Sheet Flow: FL(SI) <1 Concentrated Flow: FL(SI) > 1 Where: FL = watershed flow length (ft) SI = interface slope (normal to flow) (ft/ft) Use of Grass Buffers Sheet flow of stormwater through a grassed area provides some benefit in pollutant removal and volume reduction even when the geometry of the BMP does not meet the criteria provided in this Fact Sheet. These criteria provide a design procedure that should be used when possible; however, when site constraints are limiting, this treatment concept is still encouraged. Equation GB -2 Equation GB -3 6. Flow Distribution: Flows delivered to a grass buffer must be sheet flows. Slotted or flush curbing, permeable pavements, or other devices can be used to spread flows. The grass buffer should have relatively consistent slopes to avoid concentrating flows within the buffer. A level spreader should be used when flows are concentrated. A level spreader can be a slotted drain designed to discharge flow through the slot as shown in Photo GB -2. It could be an exfiltration trench filled with gravel, which allows water to infiltrate prior to discharging over a level concrete or rock curb. There are many ways to design and construct a level spreader. They can also be used in series when the length of the buffer allows flows to re - concentrate. See Figure GB -2 for various level spreader sections. Photograph GB -2. This level spreader carries concentrated flows into a slotted pipe encased in concrete to distribute flows evenly to the grass buffer shown left in the photo. Photo courtesy of Bill Wenk. November 2010 Urban Drainage and Flood Control District GB -3 Urban Storm Drainage Criteria Manual Volume 3 T-1 Grass Buffer Photos GB -3 and GB -4 show a level spreader that includes a basin for sedimentation. Concentrated flows enter the basin via stormsewer. The basin is designed to drain slowly while overflow is spread evenly to the downstream vegetation. A small notch, orifice, or pipe can be used to drain the level spreader completely. The opening should be small to encourage frequent flows to overtop the level spreader but not so small that it is frequently clogged. 7. Soil Preparation: In order to encourage establishment and long- term health of the selected vegetation, it is essential that soil conditions be properly prepared prior to installation. Following site grading, poor soil conditions often exist. When possible, remove, strip, stockpile, and reuse on -site topsoil. If the site does not contain topsoil, the soils should be amended prior to vegetation. Typically 3 to 5 cubic yards of soil amendment (compost) per 1,000 square feet, tilled 6 inches into the soil is required in order for vegetation to thrive, as well as to enable infiltration of runoff. Additionally, inexpensive soil tests can be conducted to determine required soil amendments. (Some local governments may also require proof of soil amendment in landscaped areas for water conservation reasons.) Photograph GB -3. This level spreader includes the added benefit of a sedimentation basin prior to even distribution of concentrated flows from the roadway into the grass buffer. Photo courtesy of Bill Wenk. Photograph GB -4. Maintenance access is provided via the ramp located at the end of the basin. Photo courtesy of Bill Wenk. 8. Vegetation: This is the most critical component for treatment within a grass buffer. Select durable, dense, and drought tolerant grasses to vegetate the buffer. Also consider the size of the watershed as larger watersheds will experience more frequent flows. The goal is to provide a dense mat of vegetative cover. Grass buffer performance falls off rapidly as the vegetation coverage declines below 80% (Barrett et a1.2004). GB -4 Urban Drainage and Flood Control District November 2010 Urban Storm Drainage Criteria Manual Volume 3 Grass Buffer T-1 Turf grasses such as Kentucky bluegrass are often selected due to these qualities' Dense native turf grasses may also be selected where a more natural look is desirable Once established, these provide the benefit of lower irrigation requirements See the Revegetation chapter in Volume 2 of this manual with regard to seed mix selection, planting and ground preparation Depending on soils and anticipated flows, consider erosion control measures until vegetation has been established Irrigation Grass buffers should be equipped with irrigation systems to promote establishment and survival in Colorado's semi -and environment Systems may be temporary or permanent, depending on the type of vegetation selected Irrigation application rates and schedules should be developed and adjusted throughout the establishment and growing season to meet the needs of the selected plant species Initially, native grasses require the same irrigation requirements as bluegrass After the grass is established, irrigation requirements for native grasses can be reduced Irrigation practices have a significant effect on the function of the grass buffer Overwatering decreases the permeability of the soil, reducing the infiltration capacity and contributing to nuisance baseflows Conversely, under watering may result in delays in establishment of the vegetation in the short term and unhealthy vegetation that provides less filtering and increased susceptibility to erosion and nlling over the long term 10 Outflow Collection Provide a means for downstream conveyance A grass swale can be used for this purpose, providing additional LID benefits Construction Considerations Success of grass buffers depends not only on a good design and long-term maintenance, but also on installing the facility in a manner that enables the BMP to function as designed Construction considerations include • The final grade of the buffer is critical Oftentimes, following soil amendment and placement of sod, the final grade is too high to accept sheet flow The buffer should be inspected prior to placement of seed or sod to ensure appropriate grading • Perform soil amending, fine grading, and seeding only after tributary areas have been stabilized and utility work crossing the buffer has been completed • When using sod tiles stagger the ends of the tiles to prevent the formation of channels along the joints Use a roller on the sod to ensure there are no air pockets between the sod and soil • Avoid over compaction of soils in the buffer area during construction to preserve infiltration capacities • Erosion and sediment control measures on upgradient disturbed areas must be maintained to prevent excessive sediment loading to grass buffer 1 Although Kentucky bluegrass has relatively high irrigation requirements to maintain a lush, green aesthetic, it also withstands drought conditions by going dormant Over -irrigation of Kentucky bluegrass is a common problem along the Colorado Front Range, and it can be healthy, although less lush, with much less irrigation than is typically applied November 2010 Urban Drainage and Flood Control District GB -5 Urban Storm Drainage Criteria Manual Volume 3 T-1 Grass Buffer W U IL Z O' OI G VV.

This letter has been prepared to describe the drainage basin revisions associated with the proposed improvements to the Site. The High Plains K-9 Connections Improvements project consists of 2.84 acres located at 16876 Longs Peak Rd. in Weld County. The Site currently consists of a single-family residential structure, an approx. 2000 SF barn structure, gravel driveway/parking, and undeveloped grass pasture/landscape area. The proposed development add an additional approx. 3000 SF detached training structure, as well as additional gravel parking, and will maintain the existing zoning and use. The composite imperviousness of the existing Site is 10%, denoted in the attached Drainage Plan as Basin A-1. The site drains to the south and east at slopes between 1-2% and is tributary to the adjacent Greeley Number 2 Canal, denoted in the attached Drainage Plan as Design Point A- 1. This site is located on FEMA FIRM map number 08123C1530E, dated 1/20/2016, and lies within Zone X, which is defined as areas determined to be outside the 0.2% annual chance floodplain. This site is composed predominantly of NRCS Soil Type A. The composite imperviousness of the developed Site is 14% and will maintain the historic drainage patterns of the existing site. The attached calculations show minimal increases in runoff during the Minor (5 -year) and Major (100 -year) storm events, and are also summarized below: RATIONAL CALCULATIONS SUMMARY DESIGN POINT TRIBUTARY BASINS TRIBUTARY AREA (AC) PEAK FLOWS CFS Q5 O100 On -Site Basins Al Existing —Al 2.84 0.30 2.12 Al Proposed —Al 2.84 0.46 2.53 Final Drainage Compliance Letter High Plains K-9 Connections Improvements —Weld County, CO ' It is our determination that the development of the High Plains K-9 Connections Improvements ,will have minimal impacts on the existing improvements surrounding the Site, based upon the negligible increases in peak runoff resulting in the development of this project No further stormwater infrastructure improvements are proposed at this time Sincerely, ((]]Ppp REGIS 11.

Warning: Soil Map may not be valid at this scale. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for map measurements. Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required. This product is generated from the USDA-NRCS certified data as of the version date(s) listed below. Soil Survey Area: Weld County, Colorado, Southern Part Survey Area Data: Version 19, Jun 5, 2020 Soil map units are labeled (as space allows) for map scales 1:50,000 or larger. Date(s) aerial images were photographed: Jul 19, 2018 -Aug 10, 2018 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. Rating Options Aggregation Method: Dominant Condition USDA Natural Resources Web Soil Survey 8/5/2021 Conservation Service National Cooperative Soil Survey Page 3 of 4 Hydrologic Soil Group —Weld County, Colorado, Southern Part Aggregation is the process by which a set of component attribute values is reduced to a single value that represents the map unit as a whole. A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not. For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of 60 indicates that the corresponding component typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Dominant Condition" first groups like attribute values for the components in a map unit. For each group, percent composition is set to the sum of the percent composition of all components participating in that group. These groups now represent "conditions" rather than components. The attribute value associated with the group with the highest cumulative percent composition is returned. If more than one group shares the highest cumulative percent composition, the corresponding "tie -break" rule determines which value should be returned. The "tie -break" rule indicates whether the lower or higher group value should be returned in the case of a percent composition tie. The result returned by this aggregation method represents the dominant condition throughout the map unit only when no tie has occurred. Component Percent Cutoff: None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. Tie -break Rule: Higher The tie -break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie.
