1. Prior to any ground disturbance on the site one 'inspection with LDAP staff is required. Issuance of this plan does not relieve the permit holder and or the 15. Approval of this Erosion Sediment Control Plan ESCP does not constitute an approval of permanent road or drainage design systems e.g. size and location
contractor from all other permitting requirements. Prior to beginning construction activities, all other necessary approvals shall be obtained. of roads, pipes, channels, retention facilities, utilities, etc.).
2. The erosion and sediment control measures shown on this Erosion Sediment Control Plan (ESCP) are the minimum requirements for anticipated site 16. The erosion and sediment control measures shown on this Erosion Sediment Control Plan (ESCP) must be constructed in conjunction with all clearing and
conditions. During the construction period, these measures shall be upgraded as needed for unexpected storm events and to ensure that sediment and grading activities in such a manner as to insure that sediment and sediment laden water does not enter the stormwater system, roadways, or violate applicable
sediment -laden water does not leave the site. A copy of this ESCP must be kept on site. Changes to the ESCP must also be submitted in the form of an water standards.
Action Plan to DEQ or its Agent for approval. (Schedule A.71)
17. All work performed by utility companies for this project, including placement of appropriate erosion and sediment control measures, finished groding,

The implementation of the ESCP and construction, maintenance, replacement, and upgrading of the erosion and sediment control measures is the responsibility of seeding, mulching and clean up is governed by the conditions and requirements of this erosion control permit. The assurance that these requirements are met

registrant shall be responsible for maintenance after the lots are approved, until the lots are sold and the 1200 -C permit is terminated. (Schedule A.4.a.) and
(Schedule D.3.) 18. Soil stockpiled during the wet weather season (October 1 through April 30) shall be covered with polyethylene plastic sheeting and secured tightly in place
with an approved anchoring system, to ensure the stockpile is not exposed to rain or creating sediment laden run -off. Energy dissipaters and other control

responsibility of the permit holder and or the contractor until all construction is completed and accepted and vegetation / landscaping is established.
19. Stabilized construction entrances / exits shall be installed at the beginning of construction and maintained for the duration of the project. Additional
5. The boundaries of the clearing limits shown on this plan shall be clearly flogged in the field by the engineer prior to construction. During the construction measures may be required to insure that all paved areas are kept clean for duration of the project.
period no disturbance beyond the flagged clearing limits shall be permitted. The flagging shall be maintained by the applicant / contractor for the duration of
construction. 20. Catch basin / curb inlets shall be protected by an approved method to prevent sediments from entering the stormwater system. Approved bamer methods
6. The erosion and sediment control measures on active sites shall be inspected and maintained at least once every seven (7) calendar days, before weekends
& hollidays and within the 24 hours after any storm event of greater than 0.5 inches of rain per 24 -hour period. Measures shall be inspected by contractor
after each rainfall and at least daily during prolonged rainfall. Any required repairs or adjustments shall be made immediately.
7. All erosion and sediment control measures shall be protected from damage at all times. Control measures shall remain in place until permanent
re- vegetation has been stabilized. Any measure that is damaged or destroyed shall be repaired or replaced immediately.
8. Any areas of exposed soils, including roadway embankment, that will not be disturbed for two days during the wet season (October 1 to April 30) or seven
days during the dry season (May 1 to September 30) shall be immediately stabilized with an approved ECS method (seeding & mulching with straw, bark,
compost, or plastic covering, etc.)
9. Street sweeping shall be performed as needed or when directed by the City inspector to insure public right-of-ways are kept clean and free of debris.
10. When trucking saturated soils from the site, either water -tight trucks shall be used or loads shall be drained on site until dripping has been reduced to no
more than one gallon per hour. Sediment laden water will not be allowed to enter the stormwater system.
11. Extracted ground water from excavated trenches shall dispose of in a suitable manner without damage to adjacent property. Dewatering systems shall be
designed and operated so as to prevent removal of the natural sails and so that the groundwater level outside the excavation is not reduced to the extent that
would damage or endanger adjacent structures or property. Approval of the system does not guarantee that it will meet the outcomes or be acceptable for use
in all situations. Modifications to the system will be required if the compliance can not to met. At no time will sediment laden water be allowed to leave the
construction site.
12. A supply of materials necessary to meet compliance and implement the LDAP or other best management erosion practices under all weather conditions shall
be maintained at all times on the construction site.
13. No hazardous substances, such as paints, thinners, fuels and other chemicals shall be released onto the site, djacent properties, or into water features, the
City's storm water system, or related natural resources.
14. The ESC facilities shall be inspected by the contractor and maintained to ensure continued proper functioning. Written records shall be kept of weekly
reviews of the ESC facilities during the wet season (October 1 to April 30) and of monthly reviews during the dry season (May 1 to September 30).

is achieved.
22. Issuance of the erosion permit does not relieve the permit holder from all other permitting requirements. Prior to beginning construction activities, all other
necessary approvals shall be obtained.
23. BMPs that will be used to prevent or minimize stormwater from being exposed to pollutants from spills, no discharge of concrete truck wash water, vehicle and equipment
