Signature. i Printed Name Kari C/: fit- Date C e 30 - /fot Approval or Denial 11l be issued hi I l;eyl c'd Date V29/1(� Approved by Rezoning Questionnaire for Coastal Chemical Co., LLC Introduction Coastal Chemical Co., LLC is a subsidiary of Brenntag, a chemical distributor with locations in 72 countries. Locally in Northern Colorado, Coastal Chemical Co., LLC operates a small facility east of Greeley with a physical address of 122 E. 4th Street Road, Greeley, CO 80631. On site, we store various chemicals, coolants and lubricants and supply them to our oil and gas customers in the field. These field locations include drilling rigs, compressor stations, compressor plants, refineries, upstream and midstream pipelines. At our current location, Coastal Chemical Co., LLC maintains an office, indoor storage for some of our products, a tank battery as well as three distribution trucks. These trucks consist of two fluid "bob trucks" and one "stake bed" truck. In 2014, our Greeley facility received Coastal Chemical Co., LLC's 2014 "Safety Facility of the Year" recognition. (Exhibit A) Space is tight at our current location. Business projections for 2019 show the volume of our onsite storage increasing by 400% with approximately 10 trucks (at full build out) utilizing our site at one given time. We anticipate that one of these trucks will be a transportation truck (a semi- trailer truck). In May 2014, Coastal Chemical Co., LLC purchased the lot immediately to the south of our current location, which is zoned Commercial (C-1). (Exhibit B) Our current lot is known as Lot 6, and our new lot is known as Lot 2. Our new southern lot adds about five and 1/2 acres of needed space for our growing operations. Our location on Lot 6 is zoned Industrial (I-3) along with our neighbors on E. 4th Street Road. To the east and southeast, our neighbors are zoned Industrial (I-2). Our neighbors to the west and south of our new property (Lot 6) are located in the City of Greeley and zoned Industrial medium intensity (I -M). (Exhibit D) By this application, Coastal Chemical Co., LLC respectfully requests the County to permit a change of zone from Commercial (C-1) to Industrial (I-3) for our new southern lot. We desire to use the southern lot for added storage facilities and to allow room for distribution trucks to load and unload. We expect about 30 employees to use the combined northern and southern lots, and the hours of our operation will be 5:00 a.m. to 7:00 p.m. In time, we plan to install an above ground tank farm for future use, two or three steel sheds and concrete containment stations for above- ground storage. Size estimates include 30'x100' for the concrete pads, two 30'x80' concrete slabs, two 30'x80' lean to shed and a steel 30'x80' building. Coastal Chemical Co,, LLC has submitted a Site Plan Review (SPR) application to the Planning Department to approve these uses. Page 1 Rezoning Questionnaire for Coastal Chemical Co., LLC Question 1: How is the proposed rezoning consistent with the policies of the Weld County Code, Chapter 22? If the proposed rezoning is not consistent with the Comprehensive Plan, explain how the proposed zoning will correct what the applicant perceives as the changing conditions in the area. Permitting the change of zone is consistent with the Weld County Comprehensive Plan by allowing conversion of commercial land to industrial uses where industrial uses already exist. The property is completely boarded by Industrial zoned areas: Industrial (I-3) in Weld County and Industrial (I -M) in the City of Greeley. Changing the zone to Industrial (I-3) from Commercial (C -I) makes the zoning congruent with the surrounding parcels boarding this lot. Rezoning the property is consistent with the Comprehensive Plan's guiding principles (§ 22-1- 120) to employ land use policies which are flexible enough to adapt to the specific location and circumstances, and respect the right of property owners to make beneficial use of their property. Coastal Chemical Co., LLC will continue its record of maintaining exceptional safety at its Greeley facility, which earned it the 2014 Safety award in the company. We also believe the cumulative impact on the surrounding area will be nominal. We obtained support from many of our neighbors, and their consent to use our access on E. 4th Street Road to reach the change of zone area. (Exhibit C) Permitting the change of zone is consistent with the County's goal of establishing industrial areas to support a balanced and diversified economy. (§ 22-2-70.A). It will further the County's policy of promoting industrial uses within municipalities, County Urban Growth Boundary areas, Intergovernmental Agreement urban growth areas, growth management areas as defined in municipalities' comprehensive plans, the Regional Urbanization Areas, Urban Develop Nodes, along railroad infrastructure or where adequate services are currently available or reasonably obtainable. (§ 22-2-80.A I.Goal.l) The change of zone area falls within a development node (Exhibit E), and already has access to adequate services because it is connected with our northern lot. The City of Greeley provides water and sewer service to our northern lot, and would provide the same for Lot 2 if necessary. Changing the zone will encourage industrial development within this existing industrial area. (§ 22-2-80.A. 2. I. Policy 1.2). Finally, rezoning is also consistent with recognizing that the oil and gas industry plays an integral part in Weld County's economy -- with substantial direct and indirect impacts on current and future land use. (§ 22-5-90.A). While Coastal Chemical Co., LLC is not an oil and gas production company itself, we supply necessary components for oil and gas companies in the fields of Weld County. Permitting the change of zone allows Coastal Chemical Co., LLC to grow our capacity to meet the supply needs of oil and gas operations in Weld. Page 2 Rezoning Questionnaire for Coastal Chemical Co., LLC Question 2: How will the uses allowed by the proposed rezoning be compatible with the surrounding land uses? Include a description of existing land uses for all properties adjacent to the subject property. To the north, the change of zone area is boarded by parcels owned by the applicant (Coastal Chemical Co., LLC), Sharp Bros. Seed Company, and John and Antoinette Schiestel. All three northern parcels are part of the Geisert Industrial PUD and zoned Industrial (1-3). (Exhibit B and B-1) Lawrence and Lois Monroe own the parcel directly to the east, which is zoned Industrial (1-2). Plains Marketing LP own the two lots to the west, which are mostly within the City of Greely and zoned Industrial medium intensity (I -M), but the eastern third of these parcels lie outside the city and are zoned Commercial (C-1). (Exhibit B and Exhibit D) BGT Properties LLC owns the parcel to the south and is zoned Industrial medium intensity (I -M) by the City of Greeley. The Sharp Bros. operate a seed supplier business, maintaining a storage warehouse and an office building on site, To the best of our knowledge, our northern neighbor, John and Antoinette Schiestel, operate an environmental restoration / cleaning company on their property. Our western neighbor, Plains Marketing, operates a crude oil hauling business. On site, they maintain, store and dispatch their trucks to pull oil from drilling rigs and deliver to transfer stations. Our southern neighbor, BGT Properties, LLC runs a farm equipment sales and repair business. On site, they sell, repair, and service farming equipment. To the east, Lawrence and Lois Monroe (Rocky Mountain Inspection Services), run a drill pipe supply and inspecting business. On site, they inspect drilling pipes for the oil and gas industry, sell drill pipe and deliver them to customers in the field. From a bird's eye view, the change of zone area is an island because the surrounding land is zoned industrial. Rezoning Lot 2 to industrial will be compatible with the adjacent areas because they are already zoned industrial, and permit industrial uses. It will also form a cohesive industrial area, strengthen the industrial economic base and add jobs to the local economy. The parcel is located within the City of Greeley's Long Range Expected Growth Area, and the City's Northeast industrial land use guidance area. (Exhibit G). Question 3: Will the property use a septic system or public sewer system? Adequate sewer or septic systems can be made available to Lot 2, but Coastal Chemical Co., LLC does not plan to require either on Lot 2. Our employees will access them from our office building on Lot 6. The City of Greeley provides water and sewer service to Lot 6. Question 4: Who will provide adequate water, including fire protection, to the property? Adequate water can be made available to Lot 2, but as stated above, Coastal Chemical Co., LLC does not intend to supply Lot 2 with water because Lot 6 provides adequate water for use of both properties. The City of Greeley supplies water to Lot 2. Given that both lots are Page 3 Rezoning Questionnaire for Coastal Chemical Co., LLC located just outside the eastern boundary of the City of Greely, the Western Hills Fire Protection District is responsible for providing fire protection, The website for the Western Hills Fire Protection District states that it provides fire protection through a contract with the City of Greeley Fire Department. For emergency vehicle access, there is a 30 foot wide permanent easement connecting Lot 2 with 1st Avenue to the west. (Exhibit I) We will keep access to Lot 2 locked through a lock box. Question 5: Does the property have soils with moderate or severe limitations for construction? If yes, the applicant shall submit information which demonstrates that the limitations can be overcome. The geotechnical report by CTL / Thompson Inc. shows that the soils do not present moderate to severe limitations to planned construction provided its recommendations and design criteria are followed. Coastal Chemical Co., LLC will follow the recommendations contained in the report (Exhibit F) and conditions set through the Site Plan Review process. CTL Thompson, a geotechnical engineering consultant, will also be retained as a third -party inspector to perform open -hole soils inspections and density testing during construction. Its proposed service agreement is attached. (Exhibit H) Question 6: Is the road and/or highway facility providing access to the property(ies) adequate to meet the requirements of the proposed zone district? If not, the applicant shall supply information demonstrating the willingness and financial capability to upgrade the road and highway facilities. The road providing access to our northern lot on E. 4th Street Road is adequate in size to provide access to our southern lot. Coastal Chemical Co., LLC will construct a 300 foot asphalt road through our northern lot connecting E. 4th Street Road with our southern lot. We desire to make our trucks access the southern lot in this way to maintain onsite security. Given that we are a distributor of chemicals to the oil and gas industry, we must ensure onsite security of the chemicals stored. Requiring our trucks to enter through the northern lot maintains security by helping us monitor who comes in, goes out, and otherwise accesses our worksite. Driving across 300 feet of asphalt will also help abate dust and debris from trucks leaving the southern lot before entering public roadways from E. 4th Street Road. There is also a 30 foot wide permanent easement connecting Lot 2 with 1st Avenue to the west. However, it is not practical, on a routine basis, to access Lot 2 across the easement because it does not provide adequate turning radius for tractor trailer units. Northbound trucks making a right turn into the Industrial PUD area must then make an immediate right turn onto 1st Avenue. Then, after making the turri, the trucks must make an almost immediate left turn onto the easement. The short distance between the right turn onto 1st Avenue and the left turn onto the easement does not provide enough turning -room for large hauling trucks, Page 4 Rezoning Questionnaire for Coastal Chemical Co., LLC Question 7: Is the change of zone area located in a Flood Hazard Overlay District? The change of zone area is located in a Flood Hazard Overlay District. Coastal Chemical Co., LLC has requested a Flood Hazard Development permit from the Department of Planning Services. All required materials have been submitted for approval. Question 8: Is the change of zone area located in a Geologic Hazard Overlay District? The change of zone area is not located in a Geologic Hazard Overlay District Question 9: Is the change of zone area located in the AP (Airport) Overlay District? The change of zone area is located in the AP (Airport) Overlay District. Page 5 Monday, July 21, 2014 via Hand Delivery To all Neighbors -of Coastal Chemical, As you may already know, your neighbor, Coastal Chemical, Co., LLC, has purchased a lot directly south of its current building. That lot and property is better described and defined as Lot 2 on the map included with this letter. Coastal Chemicals intent is to rezone Lot 2 and create a storage and warehousing facility for its current and future business needs. hr order to facilitate safety and security and best business practice, Coastal Chemical desires to have access only through its already owned and existing property and having such traffic move south into Lot 2. In order to accommodate that, an increase in traffic may likely occur through the PUD east on 4th Street Road and the access as it currently exists. This increase ovill be nominal, however in order to rezone Lot 2, the County is requesting us to have all business owners and property otvrrers that access off of East ea Street Road to give their, consent in order to move forward with the rezoning process. Included with this letter is an acknowledgment and consent form, If you are an owner or authorized agent of the company or property at your location, please sign the consent form and return to our office as soon as possible, As always, we can be contacted at our facility if you have any E iiestions regarding this process and how it may impact the surrounding area F ". will be coming around to each one of you individually, to explain the process and to outline our future intentions. If you need further clarification, please do not hesitate to call. Thank you in advance for your time on this matter. Very Truly Yours, Robert Cl.

COASTAL CHEMICAL FACILITY CIL IT PROJECT NO. FC06005.125 i SCOPE This report presents the results of our Geotechnical Investigation for the proposed chemical storage facility in Greeley, Colorado. The purpose of the In- vestigation was to evaluate the subsurface conditions and provide foundation recommendations and geotechnical design criteria for the project. The scope was described in our Service Agreement (FC-14-0386, dated October 22, 2014). The report was prepared from data developed during field exploration, la- boratory testing, engineering analysis and experience with similar conditions. The report Includes a description of subsurface conditions found in our explorato- ry borings and discussions of site development as influenced by geotechnical considerations. Our opinions and recommendations regarding design criteria and construction details for site development, foundations, lateral earth loads, pavements and drainage are provided. If the proposed construction changes, we should be requested to review our recommendations. Our conclusions are summarized In the following paragraphs. SUMMARY OF CONCLUSIONS 1, Soilsencountered in our borings consisted of approximately 4% to 6 feet of sandy clay over 4% to 7 feet of clayey sand overlying sand and gravel. Weathered claystone bedrock was encountered in Tll- 1 at a depth of about 26 feet. Groundwater was encountered in all three borings during drilling at depths of 171 to 19 feet. Ground- water was measured several days later at a depth of 151/2 feet in one boring. Existing groundwater levels are not expected to signifi- cantly affect site development. 2, The 4'A to 6 feet of sandy clay encountered in our borings was considered probable fill. Information from our client indicates that fill placement at the site was uncontrolled; the existing fill is not considered suitable for structural support. Fill material In the area of proposed construction should be over -excavated down to the na- tive soil and recompacted according to the Fill Placement section of this report, C(3RS, INC. COASTAL CHEMICAL FACILITY CTL IT PROJECT NO. FCO6805-125 1 3. We believe the proposed structures can be constructed on a rein- forced mat foundation placed on properly compacted fill, Founda- tion design and construction recommendations are presented in this report, 4. The presence of expansive soils and bedrock constitutes a geologic hazard. There is risk that foundations will heave or settle and be damaged, We believe the recommendations presented in this re- port will help to control risk of damage; they will not eliminate that risk. SITE CONDITIONS The site is located southeast of the intersection of Highway 85 and 4th Street in Greeley, Colorado (Figure 1), The site is relatively flat with a small drainage passing roughly east -west across the approximate center of the lot. The Cache la Poudre river flows about %-mile to the south and several small reservoirs lie 1/4 -mile to f2 -mile to the east, Ground cover consisted of natural grasses and weeds. PROPOSED CONSTRUCTION Based on conversations with our client, we understand the proposed con- struction will consist of a containment slab for liquid chemical storage tanks and several concrete paved off-loading aprons. Preliminary sizing indicates the con- tainment area will be about 45 feet by 135 feet. INVESTIGATION Subsurface conditions were investigated by drilling three borings to depths of approximately 20 to 30 feet, The approximate locations of the borings are shown on Figure 1. Our field representative observed drilling, logged the soils and bedrock found in the borings and obtained samples. Sampling was per- formed by driving a 2.5 -inch O,D, modified California sampler with blows of a 140 -pound hammer falling 30 inches. This method is similar to the standard CURS, INC. COASTAL CHEMICAL FACILITY CTL I T PROJECT NO. FC06806. t2S 2 penetration test, and is typical for local practice. Groundwater measurements were taken during drilling and several days after drilling. Summary logs of the borings, including results of field penetration resistance tests, are presented on Figure 2. Samples obtained during drilling were returned to our laboratory and visu- ally examined by the geotechnical engineer for this project. Laboratory analyses included moisture content, dry density, swell -consolidation, and particle -size analysis, Results of laboratory tests are presented in Appendix A and summa- rized in Table A -I. SUBSURFACE CONDITIONS Soils encountered in our borings consisted of approximately 4% to 6 feet of sandy clay over 4% to 7 feet of clayey sand overlying sand and gravel. Weath- ered claystone bedrock was encountered in TI -I-1 at a depth of about 26 feet. Groundwater was encountered in all three borings during drilling at depths of 17% to 19 feet. Groundwater was measured several days later at a depth of 15% feet in one boring. Existing groundwater levels are not expected to significantly affect site development. Further description of the subsurface conditions Is pre- sented on our boring logs (Figure 2) and in our laboratory testing (Appendix A). Existing Fill The 4% to 6 feet of clay material found in our borings was considered probable fill. Information from our client indicates that placement of the fill was uncontrolled; the existing fill should be considered unsuitable for structural sup- port, Swell -consolidation testing on two samples of the fill indicated swells of 5.0 and 6.9 percent after welling under approximate overburden pressures. The ex- isting fill should be over -excavated down to native soil and recompacted accord- ing to the Fill Placement section of this report, CURS, INC. COASTAL CHEMICAL FACILITY en l T PROJECT NO. PC06805 125 3 Natural Soil Native soils encountered in our borings consisted of clayey sand over sand and gravel, Based on field penetration test results, the clayey sand classi- fied as loose to medium dense while the underlying sand and gravel classified as medium dense to dense. The sand soils encountered are considered low - swelling to non -expansive based on laboratory testing and our experience, Bedrock Weathered claystone was encountered in TH-1 at a depth of about 26 feet. The claystone is considered expansive; however, bedrock at this depth is not likely to have a significant effect on the performance of shallow foundations. GEOLOGIC HAZARDS Our investigation addressed potential geologic hazards including expan- sive soils and seismicity that should be considered during planning and construc- tion. None of these hazards considered will preclude proposed construction, The following sections discuss each of these geologic hazards and associated development concerns. Expansive Soils Expansive soils and bedrock are present at the site. The presence of ex- pansive soils and bedrock, collectively referred to as expansive or swelling soils, constitutes a geologic hazard, There is a risk that ground heave will damage slabs and/or foundations. The risks associated with swelling soils can be miti- gated, but not eliminated, by careful design, construction, and maintenance pro- cedures. We believe the recommendations in this report will help control risk of foundations and/or slab damage; they will not eliminate that risk. CO RS, INC. COASTAL CHEMICAL FACT LIP/ CILIT PROJECT NO. FCI?BSQ5-126 4 Seismicity This area, like most of central Colorado, is subject to a low degree of seismic risk, As in most areas of recognized low seismicity, the record of the past earthquake activity in Colorado is incomplete. According to the 2012 International Building Code and the subsurface conditions encountered In our borings, this site probably classifies as a Site Class D. Only minor damage to relatively new, properly designed and built build- ings would be expected. Wind loads, not seismic considerations, typically govern dynamic structural design in this area. SITE DEVELOPMENT Fill Placement The existing onsite soils are suitable for re -use as fill material provided debris or deleterious organic materials are removed. If import material is used, it should be tested and approved as acceptable fill by CTLlThompson. In general, import fill should meet or exceed the engineering qualities of the onsite soils. Ar- eas to receive fill should be scarified, moisture -conditioned and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D698, AASHTO T99). Sand soils used as fill should be moistened to within 2 percent of optimum moisture content. Clay soils should be moistened between optimum and 3 percent above optimum moisture content. The fill should be moisture - conditioned, placed in thin, loose lifts (8 inches or less) and compacted as de- scribed above. We should observe placement and compaction of fill during con- struction. Fill placement and compaction should not be conducted when the fill material is frozen. CG RS, INC. COASTAL CHEMICAL FACILITY OIL IT PROJECT NO. FC08805-i25 5 The existing fill presents a risk of settlement or heave to structures, We recommend the fill be removed and recompacted in the building area. The fill removal area should extend beyond the building footprint at least 5 feet. The ex- cavation can be filled with on -site soils, moisture -conditioned and compacted as described above. The existing fill can also affect pavements and exterior flatwork. The low- est risk alternative for exterior pavement and flatwork would also be complete removal and recompaction, The cost could be significant. If the owner can ac- cept a risk of some movement and distress in these areas then partial depth re- moval is an alternative. We suggest removal of the existing fill to a depth of 1 to 2 feet below existing grade, proof rolling the exposed subgrade, and additional removal or stabilization of areas where soft, yielding or organic soils or debris is encountered. After this, fill placement can proceed to construction grades. Site grading in areas of landscaping where no future Improvements are planned can be placed at a dry density of at least 90 percent of standard Proctor maximum dry density (ASTM D 698, AASHTO T 99). Example site grading spec- ifications are presented In Appendix B. Excavations The materials found in our borings can be excavated using conventional heavy-duty excavation equipment. Excavations should be sloped or shored to meet local, State and Federal safety regulations. Excavation slopes specified by OSHA are dependent upon types of soil and groundwater conditions encoun- tered. The contractor's "competent person" should identify the soils and/or rock encountered in the excavation and refer to OSHA standards to determine appro- priate slopes. CORS, INC. COASTAL CHEMICAL FACILITY CIL IT PROJECT NO, FCO8605.125 6 FOUNDATIONS The proposed structures should be constructed on a reinforced concrete mat foundation. Design criteria for a mat foundation developed from analysis of field and laboratory data and our experience are presented below. The builder and structural engineer should also consider design and construction details es- tablished by the structural warrantor (if any) that may impose additional design and installation requirements, Reinforced Concrete Mat 1. The reinforced concrete mat should be constructed on properly compact- ed fill following excavation of the existing fill as discussed in the pill Placement section of this report. The reinforced concrete mat foundation should be designed for a not allowable soil pressure of 2,000 psf if con- structed on the natural soli and/or properly compacted fill The soil pres- sure can be increased 33 percent for transient loads such as wind or seismic loads. 2. Reinforced slabs are typically designed using a modulus of subgrade re- action to account for slab flexibility. We recommend a modulus of 75 pounds per square inch per inch of deflection (pci), provided the existing fill is over -excavated as described previously, 3. The soils beneath foundations can be assigned an ultimate coefficient of friction of 0.4 to resist lateral loads, The ability of foundation backfill to resist lateral loads can be calculated using a passive equivalent fluid pressure of 300 pcf. This assumes the backfill is densely compacted and will not be removed. Backfill should be placed and compacted to the cri- teria in the Fill Placement section of the report. A moist unit weight of 120 pcf can be assumed for natural soils and compacted fill. These values are considered ultimate values and appropriate factors of safety should be used, Typically, a factor of safety of 1.5 Is used for sliding and 1.6 for lateral earth pressure. 4, The edges of the mats should be thickened or turned down for structural strength, 5. Materials beneath the mat foundation should be protected from frost ac- tion, We believe 30 Inches of frost cover is appropriate for this site. 6. We should be retained to observe the completed excavations for mats to confirm that the subsurface conditions are similar to those found in our borings. Coss, INC, COASTAL, CHEMICAL FACILITY CTL I T PROJECT No, FC0c605-125 7 IF BELOW GRADE AREAS No below -grade construction is planned. For this condition, perimeter drains around the foundation are not usually necessary. We should be contacted to provide foundation drain recommendations if plans change to include base- ment areas. PAVEMENTS The project will include concrete paved off-loading aprons adjoining the chemical storage tank slab. Existing fill at the site poses a threat of damage to pavements by settlement and/or heave. Fill in planned pavement areas can be either partly or completely excavated and recompacted for improved support, as described in the Fill Placement section of this report. For Portland cement con- crete (PCC) pavement at the site, we recommend a minimum 6 -inch thick pave- ment section. Pavement Maintenance Routine maintenance, such as sealing and repair of cracks, is necessary to achieve the long-term life of a pavement system. We recommend a preven- tive maintenance program be developed and followed for all pavement systems to assure the design life can be realized. Choosing to defer maintenance usually results in accelerated deterioration leading to higher future maintenance costs, and/or repair. A recommended maintenance program Is outlined in Appendix D. Excavation of completed pavement for utility construction or repair can destroy the integrity of the pavement and result in a severe decrease in service- ability. To restore the pavement top original serviceability, careful backfill com- paction before repaving is necessary. CGRS, INC. COASTAL CH MM. FACILITY CALlYPROJECT N0, FC0660S-125 8 SURFACE DRAINAGE Performance of foundations, flatwork and pavements are influenced by changes in subgrade moisture conditions, Carefully planned and maintained sur- face grading can reduce the risk of wetting of the foundation soils and pavement subgrade, Positive drainage should be provided away from foundations. Backfill around foundations should be moisture treated and compacted as described in Fill Placement, GEOTECHNICAL RISK The concept of risk is an important aspect with any geotechnical evalua- tion primarily because the methods used to develop geotechnical recommenda- tions do not comprise an exact science. We never have complete knowledge of subsurface conditions, Our analysis must be tempered with engineering Judg- ment and experience. Therefore, the recommendations presented In any ge- otechnical evaluation should not be considered risk -free. Our recommendations represent our Judgment of those measures that are necessary to increase the chances that the structures will perform satisfactorily, It is critical that all recom- mendations in this report are followed during construction, Property owners must assume responsibility for maintaining the structures and use appropriate practic- es regarding drainage and landscaping, Improvements performed after construc- tion should be completed in accordance with recommendations in this report. LIMITATIONS Although our borings were spaced to obtain a reasonably accurate picture of subsurface conditions, variations not indicated in our borings are possible, We should observe foundation excavations to confirm soils are similar to those found in our borings. Placement and compaction of fill, backfill, subgrade and CORS, INC. COASTAL CHEMICAL FACIu1Y CTL T PROJECT NO. FC06605-125 9 other fills should be observed and tested by a representative of our firm during construction. This report was prepared from data developed during our field exploration, laboratory testing, engineering analysis and experience with similar conditions. The recommendations contained in this report were based upon our understand- ing of the planned construction. If plans change or differ from the assumptions presented herein, we should be contacted to review our recommendations. We believe this investigation was conducted In a manner consistent with that level of skill and care ordinarily used by members of the profession currently practicing under similar conditions in the locality of this project. No warranty, ex- press or implied, Is made, If we can be of further service in discussing the contents of this report or in the analysis of the proposed construction from the geotechnical point of view, please contact the undersigned.

DESCRIPTION This item shall consist of the excavation, transportation, placement and compac- tion of materials from locations indicated on the plans, or staked by the Engineer, as necessary to achieve building site elevations. 2. GENERAL The Geotechnical Engineer shall be the Owner's representative. The Geotech- nical Engineer shall approve fill materials, method of placement, moisture con- tents and percent compaction, and shall give written approval of the completed fill. 3, CLEARING JOB SITE The Contractor shall remove all trees, brush and rubbish before excavation or fill placement is begun. The Contractor shall dispose of the cleared material to pro- vide the Owner with a clean, neat appearing job site. Cleared material shall not be placed in areas to receive fill or where the material will support structures of any kind. 4. SCARIFYING AREA TO BE FILLED All topsoil and vegetable matter shall be removed from the ground surface upon which fill is to be placed. The surface shall then be plowed or scarified to a depth of 8 inches until the surface is free from ruts, hummocks or other uneven fea- tures, which would prevent uniform compaction by the equipment to be used. 5. COMPACTING AREA TO BE FILLED After the foundation for the fill has been cleared and scarified, it shall be disked or bladed until it is free from large clods, brought to the proper moisture content and compacted to not less than 95 percent of maximum dry density as deter- mined in accordance with ASTM D 698 or AASHTO T 99. 6. FILL MATERIALS On -site materials classifying as CL, SC, SM, SW, SP, GP, GC and GM are ac- ceptable. Fill soils shall be free from organic matter, debris, or other deleterious substances, and shall not contain rocks or lumps having a diameter greater than three (3) inches. Fill materials shall be obtained from the existing fill and other approved sources. CORS; INC. COASTAL CHEMICAL FACILITY CTL IT PROJECT NO. FC0604b•125 B-1 7. MOISTURE CONTENT Fill materials shall be moisture treated. Clay soils placed below the building en- velope should be moisture -treated to between 1 and 4 percent above optimum moisture content as determined from Standard Proctor compaction tests. Clay soil placed exterior to the building should be moisture treated between optimum and 3 percent above optimum moisture content. Sand soils can be moistened to within 2 percent of optimum moisture content. Sufficient laboratory compaction tests shall be performed to determine the optimum moisture content for the vari- ous soils encountered in borrow areas. The Contractor may be required to add moisture to the excavation materials in the borrow area if, in the opinion of the Geotechnical Engineer, it is not possible to obtain uniform moisture content by adding water on the fill surface. The Con- tractor may be required to rake or disk the fill soils to provide uniform moisture content through the soils. The application of water to embankment materials shall be made with any type of watering equipment approved by the Geotechnical Engineer, which will give the desired results, Water jets from the spreader shall not be directed at the em- bankment with such force that fill materials are washed out. Should too much water be added to any part of the fill, such that the material is too wet to permit the desired compaction from being obtained, roiling and all work on that section of the fill shall be delayed until the material has been allowed to dry to the required moisture content. The Contractor will be permitted to rework wet material in an approved manner to hasten its drying. 8. COMPACTION OF FILL AREAS Selected fill material shall be placed and mixed in evenly spread layers, After each fill layer has been placed, it shall be uniformly compacted to not less than the specified percentage of maximum dry density. Fill materials shall be placed such that the thickness of loose material does not exceed 8 inches and the com- pacted lift thickness does not exceed 6 inches, Compaction, as specified above, shall be obtained by the use of sheepsfoot roll- ers, multiple -wheel pneumatic -tired rollers, or other equipment approved by the Engineer. Compaction shall be accomplished while the fill material is at the specified moisture content. Compaction of each layer shall be continuous over the entire area. Compaction equipment shall make sufficient trips to insure that the required dry density is obtained. CGRS, INC. COASTAL CHEMICAL FACILITY CTL IT PROJECT NO. EC06B06.125 B-2 9, COMPACTION OF SLOPES Fill slopes shall be compacted by means of sheepsfoot rollers or other suitable equipment. Compaction operations shall be continued until slopes are stable, but not too dense for planting, and there is no appreciable amount of loose soil on the slopes. Compaction of slopes may be done progressively in increments of three to five feet (3' to 5') in height or after the fill is brought to its total height. Permanent fill slopes shall not exceed 3:1 (horizontal to vertical), 10. DENSITY TESTS Field density tests shall be made by the Geotechnical Engineer at locations and depths of his choosing. Where sheepsfoot rollers are used, the soil may be dis- turbed to a depth of several inches, Density tests shall be taken in compacted material below the disturbed surface. When density tests indicate that the dry density or moisture content of any layer of fill or portion thereof is below that re- quired) the particular layer or portion shall be reworked until the required dry density or moisture content has been achieved. 11. COMPLETED PRELIMINARY GRADES All areas, both cut and fill, shall be finished to a level surface and shall meet the following limits of construction: A. Overlot cut or fill areas shall be within plus or minus 2110 of one foot. B. Street grading shall be within plus or minus 1/10 of one foot. The civil engineer, or duly authorized representative, shall check all cut and fill areas to observe that the work is in accordance with the above limits. 12. SUPERVISION AND CONSTRUCTION STAKING Observation by the Geotechnical Engineer shall be continuous during the place- ment of fill and compaction operations so that he can declare that the fill was placed in general conformance with specifications. All site visits necessary to test the placement of fill and observe compaction operations will be at the ex- pense of the Owner. All construction staking will be provided by the Civil Engi- neer or his duly authorized representative. Initial and final grading staking shall be at the expense of the owner. The replacement of grade stakes through con- struction shall be at the expense of the contractor. CORS, INC. COASTAL CHEMICAL FACILITY CTLIT PROJECT NO, FC46BO5.125 B-3 13. SEASONAL LIMITS No fill material shall be placed, spread or rolled while it is frozen, thawing, or dur- ing unfavorable weather conditions. When work is interrupted by heavy precipi- tation, fill operations shall not be resumed until the Geotechnical Engineer indi- cates that the moisture content and dry density of previously placed materials are as specified. 14. NOTICE REGARDING START OF GRADING The contractor shall submit notification to the Geotechnical Engineer and Owner advising them of the start of grading operations at least three (3) days in advance of the starting date. Notification shall also be submitted at least 3 days in ad- vance of any resumption dates when grading operations have been stopped for any reason other than adverse weather conditions. 15. REPORTING OF FIELD DENSITY TESTS Density tests performed by the Geotechnical Engineer, as specified under' Den- sity Tests" above, shall be submitted progressively to the Owner, Dry density, moisture content and percent compaction shall be reported for each test taken. 16. DECLARATION REGARDING COMPLETED FILL The Geotechnical Engineer shall provide a written declaration stating that the site was filled with acceptable materials, or was placed in general accordance with the specifications, CGRS, INC. COASTAL CHEMICAL FACILITY CTI.I T PROJECT NO. FC06805•125 B-4 APPENDIX C PAVEMENT CON$TRUCTIQN RECOMMENDATION SUBGRADE PREPARATION Moisture Treated Subgrade (MTS) 1. The subgrade should be stripped of organic matter, scarified, mois- ture treated and compacted to the specifications stated below in Item 2. The compacted subgrade should extend at least 3 feet be- yond the edge of the pavement where no edge support, such as curb and gutter, are to be constructed. 2. Sandy and gravelly soils (A -1-a, A -1-b, A-3, A-2-4, A-2-5, A-2-6, A- 2-7) should be moisture conditioned near optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698, AASI-HTO T 99). Clayey soils (A-6, A-7-5, A-7-6) should be moisture conditioned between optimum and 3 per- cent above optimum moisture content and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698, AASI-ITO T 99). 3. Utility trenches and all subsequently placed fill should be properly compacted and tested prior to paving. As a minimum, fill should be compacted to 95 percent of standard Proctor maximum dry density. 4. Final grading of the subgrade should be carefully controlled so the design cross -slope is maintained and low spots in the subgrade that could trap water are eliminated. 5, Once final subgrade elevation has been compacted and tested to compliance and shaped to the required cross-section, the area should be proof -rolled using a minimum axle toad of 18 kips per ax- le. The proof -roll should be performed while moisture contents of the subgrade are still within the recommended limits. Drying of the subgrade prior to proof -roll or paving should be avoided. 6. Areas that are observed by the Engineer that have soft spots in the subgrade, or where deflection is not uniform of soft or wet subgrade shall be ripped, scarified, dried or wetted as necessary and recompacted to the requirements for the density and moisture. As an alternative, those areas may be sub -excavated and replaced with properly compacted structural backfill. Where extensively soft, yielding subgrade is encountered; we recommend a representative of our office observe the excavation. GO RS, INC. COASTAL CHEMICAL FACILITY CTLIT PROJECT NO. FC0G805-12& C-1 PAVEMENT MATERIALS AND CONSTRUCTION Portland Cement Concrete (PCC) 1. Portland cement concrete should consist of Class P of the 2011 CDOT - Standard Specifications for Road and Bridge Construction specifications for normal placement or Class E for fast -track pro- jects. PCC should have a minimum compressive strength of 4,200 psi at 28 days and a minimum modulus of rupture (flexural strength) of 650 psi, Job mix designs are recommended and Periodic checks on the job site should be made toyeri& compliance with specifica- tions. 2. Portland cement should be Type Il "low alkali" and should conform to ASTM C 150, 3. Portland cement concrete should not be placed when the subgrade or air temperature is below 40°F. 4, Concrete should not be placed during warm weather if the mixed concrete has a temperature of 90°F, or higher. 5. Mixed concrete temperature placed during cold weather should have a temperature between 50°F and 90°F. 6. Free water should not be finished into the concrete surface. Atom- izing nozzle pressure sprayers for applying finishing compounds are recommended whenever the concrete surface becomes difficult to finish. 7 Curing of the portland cement concrete should be accomplished by the use of a curing compound. The curing compound should be applied in accordance with manufacturer recommendations. 8. Curing procedures should be implemented, as necessary, to pro- tect the pavement against moisture loss, rapid temperature change, freezing, and mechanical injury. 9 Construction joints, including longitudinal joints and transverse joints, should be formed during construction or sawed after the concrete has begun to set, but prior to uncontrolled cracking. 10. All joints should be properly sealed using a rod back-up and ap- proved epoxy sealant. CORS, INC. COASTAL CHEMICAL FACILITY CTL I T PROJECT NO. FC0eoo5-125 C-2 11. Traffic should not be allowed on the pavement until it has properly cured and achieved at least 80 percent of the design strength, with saw joints already cut. 12. Placement of portland cement concrete should be observed and tested by a representative of our firm. Placement should not com- mence until the subgrade is properly prepared and tested. CG RS. INC. COASTAL CHEMICAL FACILITY CIL IT PROJECT NO. FC8680S-126 C-3 APPENDIX D PAVEMENT MAINTENANCE PROGRAM MAINTENANCE RECOMMENDATIONS FOR FLEXIBLE PAVEMENTS A primary cause for deterioration of pavements is oxidative aging resulting in brittle pavements. Tire loads from traffic are necessary to "work" or knead the asphalt concrete to keep it flexible and rejuvenated. Preventive maintenance treatments will typically preserve the original or existing pavement by providing a protective seal or rejuvenating the asphalt binder to extend pavement life, 1. Annual Preventive Maintenance a. Visual pavement evaluations should be performed each spring or fall. b. Reports documenting the progress of distress should be kept current to provide information on effective times to apply pre- ventive maintenance treatments. c. Crack sealing should be performed annually as new cracks ap- pear. 2. 3 to 5 Year Preventive Maintenance a. The owner should budget for a preventive treatment at approxi- mate intervals of 3 to 5 years to reduce oxidative embrittlement problems. b. Typical preventive maintenance treatments include chip seals, fog seals, slurry seals and crack sealing. 3. 5 to 10 Year Corrective Maintenance a. Corrective maintenance may be necessary, as dictated by the pavement condition, to correct rutting, cracking and structurally failed areas. b. Corrective maintenance may include full depth patching, milling and overlays. c. In order for the pavement to provide a 20 -year service life, at least one major corrective overlay should be expected. CGRS, INC. COASTAL CHEMICAL FACILITY CTLIT PROJECT NO, FC068OS-125 D-1 MAINTENANCE RECOMMENDATIONS FOR RIGID PAVEMENTS High traffic volumes create pavement rutting and smooth polished surfac- es. Preventive maintenance treatments will typically preserve the original or ex- isting pavement by providing a protective seal and Improving skid resistance through a new wearing course. 1, Annual Preventive Maintenance a, Visual pavement evaluations should be performed each spring or fall. b. Reports documenting the progress of distress should be kept current to provide information of effective times to apply preven- tive maintenance. c, Crack sealing should be performed annually as new cracks ap- pear. 2 4 to 8 Year Preventive Maintenance a. The owner should budget for a preventive treatment at approxi- mate intervals of 4 to 8 years to reduce joint deterioration. b. Typical preventive maintenance for rigid pavements includes patching, crack sealing and joint cleaning and sealing. c. Where joint sealants are missing or distressed, resealing is mandatory. 3. 15 to 20 Year Corrective Maintenance a. Corrective maintenance for rigid pavements Includes patching and slab replacement to correct subgrade failures, edge dam- age, and material failure. b. Asphalt concrete overlays may be required at 15 to 20 year in- tervals to improve the structural capacity of the pavement. CARS, INC. COASTAL CHEMICAL FACILITY CIL I T PROJECT NO.
