• Include an Existing Site Plan or a copy of the topographic survey as part of the Civil Plan Package 
• All easements and setbacks shall be shown and clearly labeled on all plan sheets. Any encroachment into an easement will require a written authorization from the owner of easement allowing the encroachment. If the owner of the easement is the City of Pearland than encroachment must be approved by either with the engineering or public works department 
• Engineer shall provide the City of Pearland with proof of acceptance of the development by any other municipal agencies (i.e. TxDOT, Harris County Flood Control District, and Brazoria Drainage District 4) which have jurisdiction over the subject tract and require review and approval of all or part of the design. No permit will be issued until such proof of approval has been provided to the City of Pearland 

Cover sheet (All Commercial Development Civil Plans shall include a Cover Sheet) 

The cover sheet shall include at a minimum: 

• The Project Title 
• A Vicinity Map with a North Arrow 
• The Key Map Number 
• A Floodplain note which references the effective FEMA FIRM map number, the date of the map, and the Zone(s) which the subject site lies within. This note should also include reference any effective LOMRs, LOMAs, or CLOMAs that are relevant to the subject tract. 
• A note detailing which benchmark(s) and temporary benchmarks are used as part of the survey of the subject site. All benchmarks must either be on the same datum as the effective FEMA FIRM map or the datum adjustment must be reflected on all surveyed elevations 

Site Plan

• Clearly label all proposed buildings and existing buildings that are intend to remain. Note all proposed building footprint areas and finished floor elevations 
• Clearly show the location of all building entrances and exits and handicap accessible parking stalls 
• Label all paving area and note each pavement type 
• Label all property lines and lot lines 
• Label all adjacent properties, rights-of-way, and drainage easements 
• Clearly label the dumpster pad location(s) 

Dimension Control Plan

• The plans shall clearly dimension all drive aisle widths, driveway widths and radius returns, typical parking stalls lengths and widths, and turning radii along fire lane. 
• The building location shall be dimensionally located to a surveyed property line. 
• Include bearing and distance of all property lines and lot lines 

 Regional Offsite Drainage Area Map

• Include a Regional Drainage Area Map which shows at a minimum 2-foot contours and drainage flow path arrows which illustrates the historic drainage patterns of the areas surrounding the subject tract that may have an effect or be effected by the proposed development 
• Design shall ensure that the development shall have no adverse effects to any properties adjacent to the subject tract 

Onsite Drainage Area Map

• Include extreme event flow path arrows 
• Include 3-year drainage calculations for the proposed development 
• Include 100-year cumulative drainage calculations for all critical areas 

Paving, Grading And/Or Drainage Plan

• Grade site such that the extreme event runoff has an unobstructed flow path to the detention facility which serve the proposed development. 
• Ensure all areas required to be handicap accessible are graded in accordance with all relevant ADA criteria. 
• Ensure all driveways are in conformance with the City of Pearland criteria 
• No slope shall not have a horizontal to vertical slope ratio steeper that 4 to 1 
• Provide proof that proposed driveway culverts have sufficient capacity to serve the associative drainage. Driveway culvert shall extend to the end of the driveway radius return and shall include safety end treatments. 

Stormwater Pollution Prevention Plan 

• Include filter fabric fencing in all locations required to ensure proper filtering of all storm water runoff during construction 
• Include inlet protection for all existing and proposed inlets which will collect drainage from the subject tract during construction 
• Include reinforced filter fabric fencing at 100-foot spacing along any ditches adjacent to the subject tract 
• Provide or locate a stabilized construction entrance 

Detention Facilities

• Include all calculations related to the detention facilities either on the plans or in a report which accompanies the plan submittal 
• Detention Pond side slopes shall not have a horizontal to vertical slope ratios steeper than 4 to 1 
• Detention Ponds shall have a minimum freeboard depth of 0.5-feet 
• Proposed Detention Facilities 
  • Ensure that all proposed detention facilities have an emergency overflow path that will that will direct all runoff in excess of the capacity of the detention facility will towards the nearest right-of-way, drainage channel or area determined by the engineer to be appropriate and in conformance with historical drainage patterns 

• Existing Regional Detention Facilities 
  • Engineer must ensure that the regional detention facility was adequately sized to include the proposed development of the subject tract 
  • Engineer must ensure that the extreme event runoff has an unobstructed path to the regional detention facility. 
  • If regional detention pond was designed by others, than add information to the plans explaining the status of the detention for this project (i.e. existing or currently under construction.) Note the name of the engineering firm who designed the detention facilities, the project name, and the project number. 

• On-Line Storage / Detention Exemptions 
  • Engineer must submit a drainage study, sealed by a qualified engineer, to the City of Pearland which details the justification of on-line storage or detention exemption and must provide the City of Pearland with proof of that this study has been reviewed and approved by the municipal agency which maintains the receiving system (i.e. Brazoria Drainage District 4 or Harris County Flood Control District) 

Project within the 100-year Floodplain

• Include cross-sections of critical areas of the site showing at a minimum the existing grade, the proposed grade, and the 100-year floodplain elevation 
• Provide proof of reported floodplain fill volumes and mitigation volumes provided
